ABSTRACT

The thesis is based upon a prototype of the larger infrastructures of Carbon Capture, Utilisation and Storage (CCUS), which are utilized in order to tackle the rapid escalation of climate change and emissions. The prototypes explore carbon capture as small-scale urban factories, rather than the megastructure which may be expected. Running off the city as a resource (CO2), the manufacturing process (CCUS) materialises emissions into a tangible, informative asset. Thus, the thesis asks if urban production can contribute to the benefit of our climate and urban environment. Through technology and innovative discoveries, the Industrial Revolution introduced our urban environment to both new opportunities and new environmental challenges. Globally connected industries and manufacturing, large infrastructural networks and cheap energy - all technologies crucial to our cities and economy’s rapid growth - were developed during this period. Similarly, my thesis is based on exploring the synergies between new technology, the urban environment and environmental challenges through global, urban and local scales. The thesis is therefore a hypothetical project about climate change measures and urban industry in symbiosis. UN countries have agreed to try to stop global warming at 1.5 degrees. They will achieve this by emitting net zero greenhouse gases by 2050. Norway has announced to cut 55 percent of our greenhouse gas emissions by 2030. Det Norske Veritas (DNV) published a report that displays what measures are needed in order to achieve the goal. The report states that developing countries, aviation, shipping, heavy transport, and some heavy industries will not be able to have zero emissions by 2050, demanding for other sectors to be emission-free earlier. Instead, Europe and North America must become carbon negative by 2042, eight years before the goals of the Paris Agreement. Meaning that they not only have to cut their emissions to zero, but also capture carbon from the air. However, according to DNV, the technology that exists today is indeed sufficient to be able to achieve the climate goals. In 2019, Oslo had 1 267 060 tons of carbon dioxide being released into the air. This is roughly the average yearly emission-rate in the Municipality.

Translating this number into something more tangible, we can compare this to forest efficiency. To capture 1 millions tons of CO2 you would need over 800 square kilometers of forest, an area larger than the whole city of New York. In contrast, a carbon capture facility can capture the same amount on a 0.4 square kilometer footprint. In comparison, Oslo Municipality has about 300 square kilometers of forest, in theory enough to nearly absorb half of Oslos yearly emissions. However, the majority of Oslos trees and forests are dislocated from the urban center and polluting zones. The polluting epicenters in the denser urban area makes up the negative form of Oslos forests. My argument for climatic solutions needing to be locally embedded around its source of emissions are thus based on efficiency and size. My hypothesis is based on exploring carbon capturing in fragmented, smaller scales - closer to that of trees - which utilizes the city as a resource. The project is therefore conceptualized as a network or series of acupuncture projects, responding locally to the same challenges which similar large scale industries address in non-urban contexts. The thesis aims at exploring these potentials through the development of a prototype which is applied, calculated, and tested through varying case studies and scales in polluted city-zones in Oslo, Norway. Based on previous mapping exercises in which emissions, topographical conditions, and site categories were researched, the project is narrowed down to sites in particularly high pollution zones in Oslo. There are three site typologies, three corresponding utilisation concepts, and three corresponding urban strategies. For the strategy to be applicable to different cities and geographical conditions, I have chosen to work with a group of generic sites, which I assume can be found in many cities. The three generic sites are; Industrial buildings and areas, today very few in Oslo are not yet developed for housing or retail; unintended urban spaces, commonly found as voids appearing between infrastructure and development; and temporarily vacant buildings, which in Oslo are mostly owned by the Municipality, but not developed nor used at the moment.

First up is an industrial building and area in Oslo. These are buildingtypologies known for their flexible and large spaces for machinery and production. Filipstad in Oslo is an area under planning. As industry and production today has little to no presence in the city, the industrial areas are one by one being developed for housing. For industrial buildings, I propose a program adapted to the building's spatial qualities, in which the typology now becomes a concrete casting factory. Storing carbon in cement for concrete has been one of the first ways of commercialising capturing-waste. It allows for concrete to become a zero-emission building-material, through capturing CO2 both from the process of making cement, situating the factory in a polluted area capturing local emissions, and materializing carbon in the casting process. I exemplify how the factory mainly can produce concrete elements for urban use. These elements are bigger things such as whole facades, basketball courts and structural elements, or smaller objects flexible to be set in dense urban contexts, for people to use and interact with. The spaces surrounding the new factory will act as temporary storage. Urban elements form a dynamic concrete park after production whilst waiting for their final destination. The park will be in constant change as production changes, as each element later will be moved and become a permanent part of the urban fabric. The park can be experienced by bypassers - and depending on the element in production - interacted and played with. Post-storage, the concrete elements will be moved to their permanent spot. Urban furniture, so small they can be placed anywhere in the city and can be interacted with. Due to the carbon capacity of the material, the urban furniture acts as miniature carbon capturing elements scattered all over the city. Second up, are unintended urban spaces. These are places between infrastructure and development, left over as voids often inaccessible to the public. This particular site is jammed between the historic old town, new waterfront development, and heavy infrastructure projects. The second storage and utilisation strategy is based on plants and trees as natural carbon storage and carbon utilised in greenhouses. Plants are about 45% pure carbon, stored from absorbing carbon dioxide from the air. For this site, I propose storing and utilising carbon in a greenhouse, aiming to plant trees for the urban environment. On this site, the greenhouse acts as a tree nursery. This is a place where tree-seedlings are planted and grown to a sufficient size in a high-concentration carbon dioxide environment.

As trees grow out of the greenhouse, they need to be conditioned for harsher weather and environmental impacts found in urban contexts. Just outside the greenhouse, the seedlings or small trees are transplanted in order to strengthen and acclimatize. The outside nursery forms an ever changing forest, consisting of different species of medium sized trees - all to later be transplanted in different urban contexts. The forest and nursery forms a pathway and park-like forest for people to safely move between infrastructure and chaos. Today there are about 700 000 trees in Oslo, more or less one tree per Oslo-inhabitant. Oslo Municipality has now decided to plant 100 000 more trees in the urban area. I propose here that the tree nursery can be an extension of this plan, in which growing, grooming and planting the trees locally in the city can take place. Finally, the trees are planted in their permanent location somewhere in the urban environment. The final site category holds temporarily vacant buildings. Oslo Municipality today owns 94 buildings which are left empty and unused in the city. These unused buildings amount to over 77 000 square meters. 74 of the 94 empty properties are "unresolved", according to an overview from the Real Estate and Urban Renewal Agency (EBY). This means that future use is not finally decided by the municipality. In carbon capture-processes, water is seized when filtering humidity from the air. The harvested water is then used to cool down the processes rising to more than 900°C, further cooling the gases to 325°C and producing steam for power generation. Power produced by the facility can be utilised in different manners. Step one is utilising the energy in a circular manner, output = input for the carbon capture process. Excess energy can then be sold to the grid, or be utilised directly for immediate surroundings, be it cheap electricity to private homes, a facilitator for low rent public programs, or illuminating dark public areas. On this site I propose a streetlight strategy. The site's carbon capacity equals 102 tonnes of CO2 annually, this corresponds to an energy production that can generate electricity for 23 158 street lights or 17.1 households/public programs. With this urban strategy, I illustrate a lighting-scheme along the entire length of Akerselva, on both sides of the river with an interval of 20 meters adding up to 800 lights. With this strategy, there is still capacity for 22 358 more lights, or about 16 households or public programs. In closing, I have wanted to explore how carbon capture infrastructures are scalable from mega-structures to integrated small scale urban industries. This is based on a historic analysis of the relationship between the industrial

revolution and the urban impact of new technology. In parallel, I have developed a deep technical understanding of carbon capture technology today. The thesis has then explored the architectural potentials and potential relationship to urban contexts that carbon capture infrastructures entail, suggesting that a sustainable carbon capturing future can integrate within urban development and planning. Through my research I identified many potential answers and possible scales applicable to the hypothesis. In order to study possible scales and applications, the thesis applies the prototypes to three possible scenarios. These scenarios are generic conditions that can be found in cities throughout the world, which for this research case are deployed in Oslo, Norway. The scenarios are industrial buildings, unintended urban spaces, and temporarily vacant buildings, which the thesis argues could be replicated in many other urban contexts. The thesis then designs a proposal for each site. The proposals have the goal of demonstrating how carbon capture can generate urban and architectural form - ranging from large and small urban furniture, to trees and street lights - thus creating interactive and tangible components within the rest of the city. The thesis then posits a potential methodology of site-specific architectural proposals based on a technical CO2 analysis of each site, with the ambition to inspire other cities, architects, planners, and policymakers on realistic and tangible strategies to integrate urbanism and architecture with carbon capture technology. This will be a vital component of achieving the crucial goal of carbon neutrality in the very near future, and the thesis believes to demonstrate that architecture and urbanism have an important role to play.

INTRODUCTION

Through technology and innovative discoveries, the Industrial Revolution introduced our urban environment to both new opportunities and new environmental challenges. Globally connected industries and manufacturing, large infrastructural networks and cheap energy - all technologies crucial to our cities and economy’s rapid growth - were developed during this period. Similarly, my thesis is based on exploring the synergies between new technology, the urban environment and environmental challenges through global, urban and local scales. The thesis is therefore a hypothetical project about climate change measures and urban industry in symbiosis. There is urgency for a counter-reaction to the urban, social and environmental consequences of the Industrial Revolution, and the polluting traditions which this generation caused. As new technologies emerge and we enter a modern era of industrialisation, definitions and approaches to industry change. Heavy industry has been relocated away from city centres, due to globalization, pollution, changes in production and newer demands for dwellings and leisure in cities. Our cities no longer contain the resources or spaces conventional production requires, and these factories provide little prosperity in an urban context. Still, infrastructure and consumer trends remain, still contributing to air pollution in our urban areas.

A BRIEF INTRODUCTION TO CLIMATE CHANGE

Climate change has by the World Health Organisation been identified as the greatest threat to global health in the 21st century2. Human activity is the main cause of climate change. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland - releasing carbon dioxide into the atmosphere. Climate change is mainly caused by radiation being trapped in the atmosphere by greenhouse gases that would otherwise escape into space. Since the Industrial Revolution, carbon dioxide (CO2) emissions have increased by 50%, not decreasing with population growth and continuous burning of fossil fuels3.

INDUSTRIALISATION AND CITIES

In the mid 18th century, the Industrial Revolution began in Britain, through improvement of technologies, infrastructure and utilisation of raw materials4. It led to the uprising of factories and heavy industry, resulting in massive migration to the cities where the job opportunities were. As a consequence, industrialisation was a major driving force for urbanisation. Additionally, the high demand for factory labor generated demands for more housing, access to education, social reform and retail facilities, causing cities to grow economically and physically over a short period of time5. The urban experience was soon dominated by pollution, disease, poverty and crime, and soon thereafter, industries left the city centres and kept developing in suburbs and industrial parks on the periphery of city-borders. There were several benefits of migrating industry from residential areas, such as reducing immediate social and environmental impacts of the cities. However, opposed to the centralised factories, the industry parks lacked public transportation, closeness to their workers homes, less regulation on polluting their immediate surroundings and a lack of availability of a skilled workforce6. There are now more than thirty megacities in the world with a population of more than ten million7. In 2019, humans emitted more than 35 billion tons of carbon dioxide (CO2) into the atmosphere by burning fossil fuels. The current average global population increase is estimated at 81 million people per year, and according to researchers, by 2050, the global population is projected to rise to 9.7 billion9, leading to increased demand for resources, resulting in skyrocketing levels of emissions. Together with this development, new technologies emerge, and we enter a new era of industrialisation, which some researchers have referred to as the fourth Industrial Revolution10. How can this new wave of industrialisation and new ideas generate better urban spaces, social- and living conditions in the cities, opposed to the consequences of the Industrial Revolution?

GLOBAL FRAMEWORK

UN countries have agreed to try to stop global warming at 1.5 degrees. Member states claim they will achieve this by emitting net zero greenhouse gases by 2050. Norway has announced to cut 55 percent of its greenhouse gas emissions by 2030. Det Norske Veritas (DNV) recently published a report that demonstrates measures are needed to achieve this goal. The report states that developing countries, aviation, shipping, heavy transport and some heavy industries will not be able to have zero emissions by 2050. This means that other countries must be emission-free earlier. Europe and North America must therefore become carbon negative by 2042, eight years before the goals of the Paris Agreement. g that they not only have to cut their emissions to zero, but also capture carbon from the air14. Today, 80 % of our energy comes from fossil sources. In DNV's scenario, we will in the future have 80 % renewable energy. According to DNV, the technology that exists today is sufficient to be able to achieve the climate goals. But it needs to be scaled up and fast. To do that, strong political control is needed.DNV points to a number of tools that states must used: - A carbon tax to be introduced in all countries. In Europe, this should be at $ 250 per. tonnes by 2050. (This tax is higher than the price of carbon capturing per tonnes, which today is at $ 90-200 per tonnes) - A number of prohibitions and injunctions must be introduced. I.e, power plants based on oil and coal must be banned by the 2040s. - Streamlining of existing technology. Everything that can be electrified should be. The sectors that are difficult to electrify must switch to hydrogen, synthetic fuel or biofuel. - It must be expensive to invest in fossil energy and industry. - In addition, the state must subsidize or contribute to financing the development of renewable technology, energy storage, zero emission cars, hydrogen production and carbon capture and storage. - In addition, 20 % of the climate cuts in DNV's calculation will take place through carbon capture and storage, both from the combustion process, but also from the air. 20

CARBON CAPTURE, STORAGE AND UTILISATION

New and environmentally friendly technologies are currently being developed, including solar panels, wind turbines, batteries for electric vehicles, power-to-X and carbon capture, utilisation and storage. All of these are essential technologies for our present and future, but to reach the goals countries have pledged under the Paris Agreement, Carbon Capture, Utilisation and Storage (CCUS) is the only technology radical enough to have an impact as rapid as required17. We are still dependent on the energy from fossil fuels, and the process industry needs time to develop new production methods18. Therefore, carbon capture and storage is important to limit man-made climate change. Several pilot-projects are being done in this field, and there is common consensus that this is a necessary technology for our immediate future. Across the studies being done, there is a great need for large spaces and heavy machinery, therefore either existing factory or industrial structures are utilised, or small scale prototypes of the infrastructure are being built independently for efficiency testing. To this day the technology only exists as an experiment and testing facilities at selected industrial plants. Carbon Capture, Utilisation and Storage (CCUS) is first and foremost the process of plants and trees pulling carbon dioxide out of the air, binding it up in sugar and releasing oxygen. This is one of the most essential technologies we have. Modern technology has developed more efficient methods based on catching and storing CO2from the atmosphere, or directly from a polluting industrial plant. After the CO2 is caught it is either transported to storage facilities utilising empty oil-tanks - left dry as a result of an aggressive oilindustry - and pumped two to three kilometers underground into bedrock. Until now the technology is only tested and used in close relation to existing industries, but research shows there is potential for the industry to even Utilise (U) the material caught, exploring the possibilities of creating new materials such as bricks or energy from the waste.

To show an analogy between other early technologies which have developed exponentially, may look at solar cells and the photovoltaic effect. Solar cells were discovered as early as the 1800s,further researched, and finally in 1954 presented as a solar panel of cells that relied exclusively on light power, running a 21-inch Ferris wheel as a proof of concept. Later solar panels have evolved to be an integrated part of our lives, creating jobs, a major source for renewable energy, and is becoming both affordable and accessible. Researchers at MIT have now demonstrated the thinnest, lightest solar cells ever produced, which are 400 times more energy efficient than today's standardised panels20. Similarly, it is predicted the carbon capture technology will double its efficiency in only a few more years of development.

Scalability The structure functions much like a plant, in which a surface in contact with polluted air will absorb and bind carbon to a specific amino-liquid, before releasing pure oxygen back into the atmosphere. The carbon capture technology consists of four major unit operations: the contractor, pellet reactor, calciner and slaker23. The contractor, or surface area, brings ambient air through a filter, and will be the most visible part of a closed carbon capture plant. In high pollution zones a contractor can run on as low as 1 m/s, resulting in little to no noise pollution in the immediate surroundings24. The components are set by modular-based processes, which according to Joule Carbon Engineering means their performance varies slightly from 1Mt-CO2/year down to sizes as small as 10 kt-CO2/year, and their capital cost per unit capacity is nearly constant down to 100 kt-CO2/year, beneficial to the studies on scalability and performance.25 The diagram shows dimensions based on carbon capacity. Mini-plants will relate to the smallest dimensions that exist of the various processes, but as the plant grows, modules are added.

CCUS AND NORWAY

In 2007, the former prime minister of Norway, Jens Stoltenberg, claimed that carbon capture (CCUS) would be Norway's “moon landing”27. Ten years later, the technology was up and running with a facility at Mongstad oil refinery, today acting as an international training station and investment hub for foreign stakeholders. Shortly after, two new pilot projects were set to be realised, CCUS at the cement factory in Brevik in Porsgrunn and the waste facility at Klemetsrud28. At Klemetsrud in Oslo, bordering Viken municipality, lies a waste incineration plant, run by Fortum Oslo Varme, a 50% state-owned power company. The plant is alone responsible for the processing of Oslo's waste, and about 400 000 tonnes of CO2 emissions each year, one third of the municipality's yearly emissions. An industry which is now seeking funding for a pilot project within carbon capturing. Their goal is to capture 100% of the emissions produced, which will also cut large parts of the municipality's annual emissions. Such a large scale pilot project was set to cost 6.8 billion NOK, partly funded by the company themselves, and a 3 billion NOK contribution from the Norwegian state. The European Commission decided to spend NOK 11 billion (1.1 billion euros) to support decarbonisation projects, but it was concluded in November 2021 that the Norwegian pilot project was not on this list29.

OSLO AS A CASE STUDY

Oslo Municipality has several goals and initiatives in play to reduce the yearly emissions. The goal was to not exceed 766 000 tons of CO2 in 2020. Reducing emissions by 50% by 2020, and reducing all emissions by 95 % by 2030, compared with 1990-levels)31. Oslo's climate action areas consist of general principles and strategies covering several fields. These areas represent many solutions to the same common problem, and emphasizes that the effect is greatest where there are many small interventions that cover a larger field of application. My project fits into this mindset, as I have worked with small-scale, urban interventions in dense city contexts, rather than mega-facilities with a scale closer to one of suburban areas and industrial parks.

In 2019, Oslo had 1 267 060 tons of carbon dioxide being released into the air33. This is roughly the average yearly emission-rate in the Municipality. Translating this number into something more tangible, we can compare this to forest efficiency. To capture 1 millions tons of CO2 you would need over 800 square kilometers of forest, an area larger than the whole city of New York. In contrast, a carbon capture facility can capture the same amount on a 0.4 square kilometer footprint. In comparison Oslo Municipality has about 300 square kilometers of forest, in theory enough to nearly absorb half of Oslos yearly emissions. However the majority of Oslos trees and forests are dislocated from the urban center and polluting zones. The polluting epicenters in the denser urban area makes up the negative form of Oslos forests. Efficiency- and sizewise, this is my argument for climatic solutions needing to be locally embedded around its source of emissions.

Mapping For the strategy to be applicable to different cities and geographical conditions, I have chosen to work with a group of generic sites, which I assume can be found in many cities. The three generic sites are; Industrial buildings and areas, today very few in Oslo are not yet developed for housing or retail;unintended urban spaces, commonly found as voids appearing between infrastructure and development; and temporarily vacant buildings, which in Oslo are mostly owned by the Municipality, but not developed nor used at the moment.

Based on previous mapping exercises in which emissions, topographical conditions, and site categories were researched, the project is narrowed down to sites in particularly high pollution zones in Oslo. There are three site typologies, three corresponding utilisation concepts, and three corresponding urban strategies. The three strategies branch from their sites and form one large fabric covering the city.

In order to study possible scales and applications, the thesis applies the prototypes to three possible scenarios. These scenarios are generic conditions that can be found in cities throughout the world, which for this research case are deployed in Oslo, Norway. My thesis is focused three sites and urban strategies - Filipstad, Sørenga and Grünerløkka.

On this site, the factory acts as a concrete casting space. This is a place where carbon dioxide is materialized in cement and urban elements, before each element later is moved and becomes a permanent part of the urban fabric.

Industrial buildings

Concrete production

Urban elements

Concrete production Cement has a huge carbon-capacity, and any concrete elements in contact with polluted air, will for over a hundred years still absorb CO2 directly from the air. I exemplify how the factory mainly can produce concrete elements for urban use. These elements are bigger things such as whole facades, basketball courts and structural elements, or smaller objects flexible to be set in dense urban contexts, for people to use and interact with. Recently manufacturers have developed a technology for the concrete industry that introduces recycled CO₂ into fresh concrete to reduce its carbon footprint without compromising performance. Once injected, the CO₂ undergoes a mineralization process and becomes permanently embedded36.

Interventions The existing structure is modified to suit the new program better. A large catchment surface tilted towards the main road and polluting source, acts as a new elevated roof. Landing on interior columns and a core with new functions which holds all capturing processes, administrative and functional programs. Facing south the large open space is preserved and extended, free from constructive elements, and easy access to the outside.

The spaces surrounding the new factory will act as temporary storage. Urban elements form a dynamic concrete park after production whilst waiting for their final destination. The park will be in constant change as production changes, as each element later will be moved and become a permanent part of the urban fabric. The park can be experienced by bypassers - and depending on the element in production - interacted and played with. Poststorage, the concrete elements will be moved to their permanent spot. Urban furniture, so small they can be placed anywhere in the city and can be interacted with.

Second up, are unintended urban spaces. These are places between infrastructure and development, left over as voids often inaccessible to the public. This particular site is jammed between the historic old town, new waterfront development, and heavy infrastructure projects. The second storage and utilisation strategy is based on plants and trees as natural carbon storage and carbon utilised in greenhouses. Plants are about 45% pure carbon, stored from absorbing carbon dioxide from the air. For this site, I propose storing and utilising carbon in a greenhouse, aiming to plant trees for the urban environment.

On this site, the greenhouse acts as a tree nursery. This is a place where tree-seedlings are planted and grown to a sufficient size in a highconcentration carbon dioxide environment40. Before they are moved outside to be conditioned for harsher weather, and finally planted in its permanent location somewhere in the urban environment.

Tree nursery A greenhouse infused with CO2 enrichments allows for crops to meet their photosynthesis potential, and will increase the yield of greenhouse crops. Ambient CO2 level in outside air is about 340 ppm by volume. All plants grow well at this level, but as CO2 levels are raised by 1,000 ppm photosynthesis increases proportionately resulting in more sugars and carbohydrates available for plant growth. Depending on space provided by the site and yearly emissions in this particular area, the size of the greenhouse can vary. One can build a small-scale greenhouse for private use, or a larger structure with increased production and carbon-capacity. A typical tree can absorb around 21 kilograms of carbon dioxide (CO2) per year, however this figure is only achieved when the tree is fully grown saplings will absorb significantly less than this. Over a lifetime of 100 years, one tree could absorb around a tonne of CO241.

Interventions The greenhouse is set on top of its main polluting source, a highway ventilation-well with adjoining towers. This saves space on site, and brings our carbon capturing surface as close as possible to its source of pollution. A beam extends between the two towers and over the well, carrying the capturing surface. An internal core extrudes from the beam, creating storage space for ccs, greenhouse-functions and ventilated rooms for staff. On top is a shell of glass, containing heat, humidity and carbonized air for seedlings within the greenhouse. As the building is elevated, access is reached through three existing structures. A main entrance from a small building used to access the tunnel, and two entrances between each ventilation-tower. The nursery is organised symmetrically around its core. Allowing daylight to pass through all parts of the building, and making the nursery visible from all sides.

The outdoor tree nursery acts as a temporary and dynamic park.

Urban strategy Today there are about 700 000 trees in Oslo, more or less one tree per Osloinhabitant. Oslo Municipality has now decided to plant 100 000 more trees in the urban area42. I propose here that the tree nursery can be an extension of this plan, in which growing, grooming and planting the trees locally in the city can take place. Finally, the trees are planted in their permanent location somewhere in the urban environment. The strategic plan illustrates an example of 800 new trees along the water.

The final site category holds temporarily vacant buildings. Oslo Municipality today owns 94 buildings which are left empty and unused in the city. These unused buildings amount to over 77 000 square meters. 74 of the 94 empty properties are "unresolved", according to an overview from the Real Estate and Urban Renewal Agency (EBY)43. This means that future use is not finally decided by the municipality. In carbon capture-processes, water is seized when filtering humidity from the air. The harvested water is then used to cool down the processes rising to more than 900°C, further cooling the gases to 325°C and producing steam for power generation44. Power produced by the facility can be utilised in different manners. Step one is utilising the energy in a circular manner, output = input for the carbon capture process. Excess energy can then be sold to the grid, or be utilised directly for immediate surroundings, be it cheap electricity to private homes, a facilitator for low rent public programs, or illuminating dark public areas.

On this site, the powerhouse generates electricity for a streetlight strategy. Illuminating dark public areas nearby, and connected to the larger urban strategy of a safe path along the river.

Power distribution

Streetlight strategy

Streetlights The power of a street light differs depending on bulb-size and function, and can vary from 35 to 250 W. But it is assumed that the average streetlight utilise about 80 watts46. Equivalent to about 0.96 Kilowatt-Hours (kWh) when running the same bulb for 12 hours. A realistic time period for dark Norwegian winters. Households A study conducted by The IEA Greenhouse Gas R&D Programme (IEAGHG) in 2012 explores six different carbon capturing scenarios where power per amount of carbon captured is utilised for electricity to the grid47. With these numbers I have calculated based on amounts CO2 captured in an area, and subtracting quantity utilised for the process itself, how much power is left to be distributed to a streetlight or building. Numbers are based on average power consumption in an Oslo household, 1300 kWh48.

Interventions The existing building was previously inhabited by a nursing home. All interior walls are remaining, with bathrooms in all rooms, long halls for circulation, and no daylight passing through to common areas. All nonload bearing walls are removed, leaving vertical circulation, constructive elements, and a free plan. This operation reveals an existing internal core, which is added on to with new infrastructure for carbon capture processes, staff-functions, storage and crossing circulation. All heavy infrastructure inhabits the new reinforced core, whilst larger processes and functions utilise existing floors and structure, inhabited by power turbines for electricity production, and finally a surface area for capturing carbon. The ground floor is left as open as possible, leaving an open space for new programs, an axis from the street to the river, and a new entryway on one side, connecting the other side to an existing ramp and new stairway.

Urban strategy The site's carbon capacity equals 102 tonnes of CO2 annually, this corresponds to an energy production that can generate electricity for 23 158 street lights or 17.1 households/public programs. With this urban strategy, I illustrate a lighting-scheme along the entire length of Akerselva, on both sides of the river with an interval of 20 meters adding up to 800 lights. With this strategy, there is still capacity for 22 358 more lights, or about 16 households or public programs.

Summary In closing, I have wanted to explore how carbon capture infrastructures are scalable from mega-structures to integrated small scale urban industries. This is based on a historic analysis of the relationship between the industrial revolution and the urban impact of new technology. In parallel, I have developed a deep technical understanding of carbon capture technology today. The thesis has then explored the architectural potentials and potential relationship to urban contexts that carbon capture infrastructures entail, suggesting that a sustainable carbon capturing future can integrate within urban development and planning. Through my research I identified many potential answers and possible scales applicable to the hypothesis. In order to study possible scales and applications, the thesis applies the prototypes to three possible scenarios. These scenarios are generic conditions that can be found in cities throughout the world, which for this research case are deployed in Oslo, Norway. The scenarios are industrial buildings, unintended urban spaces, and temporarily vacant buildings, which the thesis argues could be replicated in many other urban contexts. The thesis then designs a proposal for each site. The proposals have the goal of demonstrating how carbon capture can generate urban and architectural form - ranging from large and small urban furniture, to trees and street lights - thus creating interactive and tangible components within the rest of the city. The thesis then posits a potential methodology of site-specific architectural proposals based on a technical CO2 analysis of each site, with the ambition to inspire other cities, architects, planners, and policymakers on realistic and tangible strategies to integrate urbanism and architecture with carbon capture technology. This will be a vital component of achieving the crucial goal of carbon neutrality in the very near future, and the thesis believes to demonstrate that architecture and urbanism have an important role to play.
