SOLUTIONS FOR A SUSTAINABLE FUTURE

WHAT KIND OF ENERGY DO WE USE FOR HEATING? WHAT ENSURES HYGIENICALLY CLEAN AIR AND HOW MUCH WATER DO WE NEED? AGAINST THE BACKGROUND OF SCARCE ENERGY RESOURCES, PANDEMICS AND CLIMATE CHANGE, THESE QUESTIONS ARE MORE RELEVANT THAN EVER BEFORE

In 2022, many related industries started again with trade fair presentations, showing how important and necessary personal exchange still is. ISH, the leading innovation show for Heating, Ventilation and Air Conditioning (HVAC) and Water will be back in March 2023. Four questions for Stefan Seitz, Director ISH Brand Management, about the relevance of the upcoming international industry meeting place.

THE TIME UNTIL ISH 2023 IS PASSING QUICKLY. WITH WHAT EXPECTATIONS ARE YOU LOOKING FORWARD TO THE UPCOMING EVENT?

S.S.: Anticipatory, very attentive and excited. I think that sums it up quite well. There was an ISH digital in 2021, but the personal encounter was simply missing. In this respect, I am very much looking forward to visiting our exhibitors at their stands, discovering the innovations for a sustainable

future for myself and entering in direct exchange about them. After all, the themes of the ISH absolutely hit the nerve of the times. At the leading international sanitary and HVAC event, national and international companies present the industry’s marketable solutions for water, heating and air. But I am also realistic and know that we are currently influenced by external factors, whether geopolitical or economic. Therefore, I am at the moment very focused on how the situation will develop further, but my basic attitude is of course optimistic.

WHAT TOPICS WILL BE IN FOCUS?

S.S.: The motto of ISH 2023 is “Solutions for the future”. Everything revolves around innovations that contribute to the achievement of climate protection goals and enable the responsible and efficient use of available resources. Sustainability is the very big topic. It is the connecting element between ISH Energy, consisting of heating, air-conditioning and ventilation, and ISH Water. In the Energy segment, this means that in the future we will have to become less dependent on fossil fuels and quickly increase the share of renewable energies. However, sustainable use and security of supply is also necessary with regard to our drinking water. The last extremely dry and hot summers have clearly shown this to us. In the area of Water, however, sustainability also refers to the materials used, both in production and installation. It includes an efficient hot water supply and extends to durable concepts for bathroom design. In the future, bathrooms should be designed for all generations and needs.

WHAT KIND OF ISH CAN WE EXPECT IN 2023? WILL THE MARKET LEADERS BE THERE?

S.S.: The last regular ISH took place in 2019. A lot has changed since then. This concerns both the dynamics of the industry and the trade fair as a marketing instrument. Corona, geopolitical developments and the partly gloomy economic forecasts in submarkets of the ISH have led to the participation decision being made at much shorter notice by both visitors and exhibitors. For this reason, the planning work is still in progress and new enquiries are coming in daily. In parallel, it leads to individual exhibitors deciding at short notice to withdraw from their participation in ISH. Unfortunately, this is currently the case, but only in the Water sector and mostly with national manufacturers. The main reasons given by the companies are the declining willingness to invest in the sanitation market, higher energy prices and the general global political situation. Nevertheless, they all continue to

emphasize the importance of the ISH as the leading trade fair for the sector and that the decisions were very difficult for them. This development is of course very regrettable.

Fortunately, the majority of the leading companies are still present in all areas of ISH. Currently, 1,250 companies have already signed their contracts. This corresponds to 70% compared to 2019. In addition, there are 320 companies that currently have a placement proposal or will receive one in the next few days. Therefore, it is currently difficult to estimate the final number of exhibiting companies.

Today, I can say that we have the support of the majority of all ISH exhibitors. At the moment, the reporting will focus on which cancellations have to be announced. However, it is worthwhile to look at who will be there. Because that is still the majority of companies, and they are looking forward to ISH in March 2023.

WHAT WILL ISH 2023 LOOK LIKE? WHAT IS NEW AND WHAT THEMES CAN BE SEEN WHERE?

S.S.: In the ISH Energy segment, we are placing an even stronger focus on the technologies of the future in the heating market. Electrification is progressing strongly in this segment. That is why we are concentrating suppliers of heat pumps, home energy management systems and energy storage, as well as manufacturers of complete heating systems, in Hall 12, whereas in Hall 11.0 we are focusing on suppliers of wood heating, waste gas technology as well as heat generation and heat transfer. In Hall 10, visitors will continue to find everything to do with home and building automation, energy management, together with monitoring, control and regulation technology, as well as testing equipment. As at the previous event, the focus in Hall 9 will be on solutions for heat distribution and in Hall 8 on refrigeration, air-conditioning and ventilation technology.

The Eastern part of the fair ground is all about Water. The absolute novelty here is Hall 5, where the ISH is one of the first events to feature the newly built hall with installation technology and software. Installation technology will also be on show in Halls 4 and 6. Tools and mounting materials are also to be found in Hall 6. The Bathroom Experience is at home in Halls 2, 3, 4 and the Forum. The International Sourcing section will be located in Hall 1. Thus, the unique, practical and international range of products for the sanitation, heating, ventilation and air-conditioning sector in March 2023 invites visitors to discover solutions for the most important questions of our time.

A SYSTEM CAPABLE OF REVERSING THE COURSE

EXAMPLES OF CIRCULAR ECONOMY IN THE ENERGY SECTOR

“

The world has a finite volume of natural resources and a limited ability to produce new resources”. (From the report “The use of natural resources in the economy: A Global Manual on Economy Wide Material Flow Accounting”, prepared by the United Nations Environment Programme). Our planet is not in possession of anything that is “unlimited”, and this also goes for its ability to produce new resources. The considerable increase in the demand for raw materials and energy and the increase in consumption suggest a dramatic situation in the near future, so much so that, according to NASA, at least 3 habitable planets are needed annually to meet the current demand for resources (source: Dennis Bushnell, Chief Scientist at the NASA Research Centre in Langley 2018). The issue of sustainability can no longer be considered as a “secondary aspect” of the industrial processes and development of our society. If at one time the protection of the environment could not be included among the objectives of economic manoeuvres and technological development, today it must be the starting point and must represent a constraint that, when not respected, vetoes any operation carried out within the economic and social system.

A NEW MODEL

It is evident that a system capable of reversing the course is needed. The new economic model to be adopted should aim to redefine the concept of “growth”, focusing on the benefits it can bring to society, the environment and the economy at the same time.

According to the “National Report on the Circular Economy” produced by the Circular Economy Network (CEN), the shortage and increasing price of raw materials (phenomena exacerbated before the pandemic, now even more so by the international geopolitical situation following the war in Ukraine) can only be countered thanks to a large-scale implementation of an economic model, called “Circular” (Figure 1).

“Circular Economy” means that modus operandi through which everything that is extracted or obtained from the environment and used in order to create a product, a service or energy useful for their own realisation, can

continue to be part of the economic cycle even after the satisfaction of the need for which it was conceived.

According to estimates relating to the need for industrial raw materials until 2030, at the end of the next decade the gap between demand and supply of commodities will be around 8 billion tons, and then gradually increase from year to year. Therefore, the need to adopt efficient waste management systems and reuse of waste is evident. Analysing the proposal from a strictly pragmatic and not only moral point of view, in addition to the improvement of climatic conditions, the introduction of a circular model would be a significant economic advantage. In addition to the decrease in waste materials, there would be the possibility of economic growth (an estimated increase in GDP of 0.5%) and an increase in jobs (in the EU, thanks to the circular economy, 700,000 new jobs could be created by 2030). Although it does not pass through easily viable paths in economic terms, the energy transition we need can take place through several paths, each one devoted, despite their differences, to the same purpose. The optimal energy transition must be effective, immediate and have an incisive approach. This will be possible globally only by adopting various solutions, which provide for different speeds, depending on the specific contexts.

BIOREFINERIES

Among the many renewable energy sources, biomass is the most sophisticated form of solar energy storage. Through the process of chlorophyll photosynthesis, plants are able to convert solar energy into chemical energy, then store it inside high-energy molecules. Biomass is a versatile, renewable and, above all, programmable energy source. In the last decade, biomass has also proved to be, after solar photovoltaic and wind, the renewable source with the greatest development, and the production of energy related to it has registered a constant growth.

The society in which we live is strictly dependent on oil, which is used for the production of goods or derivatives useful for the production of the same, but also and above all for fuels. Oil consumption over time

(mainly gasoline and medium distillates) is constantly increasing. The global population is projected to reach 9.7 billion in 2050, and it is expected that there will be a sharp increase in fuel demand in the near future, exacerbated by a shift towards higher standards of living even in developing countries.

According to the ENEA (National Agency for New Technologies, Energy and Sustainable Economic Development), currently the concentration of CO2 in the atmosphere is equal to about 390 ppm, with a considerable growth rate. Among the multiple causes that can be investigated, the use of fossil fuels for energy production is the main responsible for massive CO2 emissions, also representing 77% of total GHG emissions (Green House Gases). Biomass could become an economically and, above all, ecologically credible alternative.

According to the International Energy Agency (IEA), biorefining is “the sustainable transformation of biomass into a spectrum of marketable products and energy”. The biorefinery operating process guarantees a drastic reduction – greater than 70% compared to the traditional production cycle – of the emissions of polluting substances.

In biorefinery, biomass is transformed into energy, biofuels and products of basic chemistry, fine chemistry, biopolymers and bioplastics, through technologies and processes that produce minimum waste and have a low impact on the environment. The approach has similarities with traditional oil refining in fuels and oils, the only substantial difference being the starting material: biomass.

Biomass, just like petroleum, has an articulated composition, which requires a suitable split into several groups of substances, whose subsequent treatment will lead to a complete variety of products. The initial organic material (such as agricultural and forestry residues, food and other solid waste) can be broken down into multiple compounds through a cascade of reactive phases.

Currently, there are about 298 biorefinery plants throughout Europe that are dedicated to the production of biofuels, bio-oils or green chemistry intermediates.

GREEN HYDROGEN

To date, there are many reasons why hydrogen is considered one of the key energy carriers for the future energy transition:

• it is the most abundant element in the entire Universe and constitutes 75% of normal matter by mass;

• a single kilogram of H2 is capable of developing 142 MJ of energy; a considerable value compared to 56 MJ for natural gas, 45-46 MJ for petrol, diesel or kerosene, 30-32 MJ for coal and 16 MJ for wood;

• its combustion does not produce CO2 emissions or other pollutants.

Paradoxically, the fact that an element is widely present on Earth does not imply that it is readily available in the required form. Different extraction technologies give names to different types of hydrogen. The term “Green Hydrogen” refers to the production of molecular hydrogen through a process powered by energy from renewable sources. In this case, water (H2O) is split into biatomic hydrogen (H2) and oxygen through electrolysis. Scientists believe that this technology can meet 24% of the world’s energy needs and contribute significantly to the zeroing of net emissions by 2050. However, the main obstacle to achieving these goals is cost, despite the fact that the actual costs of the electrolysis process have decreased by 50% in the last five years. The main feature of this process is that it has zero environmental impact.

BLUE HYDROGEN

Although green hydrogen represents a more than viable long-term solution, analysts suggest that in the short term (until about 2045), it may not be as economically beneficial as blue hydrogen.

Blue Hydrogen refers to the production of hydrogen by fossil fuels, such as natural gas. In this case, the production plant is coupled with a system for capturing and permanently storing the CO2 produced in the process. In this way hydrogen can be generated, without emissions that are harmful to the climate. Blue hydrogen could be the key element for the transition to low-carbon energy production (Figure 2).

CCS

It is undoubtedly the technology with the greatest potential for a massive reduction in CO2 emissions in the short term (10-20 years).

The acronym CCS (Carbon Capture and Storage) indicates the entirety of all the techniques that allow:

• for the geological containment of carbon dioxide (CO2) from large combustion plants;

• the fluidisation of CO2, to allow it to be transported to a storage facility;

• the storage of CO2, i.e. its conservation, ensuring that no dispersion into the atmosphere occurs.

The International Energy Agency says that it is necessary, by 2025, to reduce current carbon dioxide emissions by at least ten times, in order to achieve the goals set for the global protection of the environment and health. The Global CCS Institute estimates that, by 2040, 2,500 CCS facilities are expected to be operational worldwide, each with a capacity to process about 1.5 million tons of CO2 per year. At the moment, CCS is the only technology available that is capable of massively reducing emissions

from large industrial plants

The invitation is to take advantage of all possible elements to become fully aware of the defects of the current system and the possibilities of renewing and reorganising it in the best possible way. The aim is to promote a more livable and, at the same time, economically and socially sustainable system. Technological development and environmental protection cannot and must not be regarded as diametrically opposed concepts, but rather their substantial complementarity must be recognised.

Capture technologies separate CO2 from other gases at the emission source

This can be a coal or gas fired power station or an industrial plant such as a steel mill or cement factory. Sufficiently high carbon prices or taxes create a business case to capture and store CO2

TRANSPORTATION STORAGE

Once captured and separated, the CO2 is prepared for transport.

In most cases, CO2 would be pumped through a pipeline to an onshore or offshore storage location lt may also be transported by a vessel.

lf CO2 is stored offshore it is transported to an injection platform or (former) oil/gas rig.

oil or gas rig

CO2 can also be used instead of stored. Researchers are exploring future use options that could generate revenue.

Permanent storage may occur in deep geological formations (saline aquifers) or depleted oil or gas fields. CO2 can also be injected into oil or gas fields to enable ‘enhanced oil recovery’: injecting CO2 squeezes out remaining reserves. In this case, CO2 is a commodity that can generate revenue

HEAT PUMPS AND REDUCTION OF DEPENDENCE ON NATURAL GAS

THE RESULTS OF A STUDY SHOW THAT HEAT PUMPS IN A RESIDENTIAL ENVIRONMENT COULD BE CRUCIAL IN A DECARBONISATION PERSPECTIVE. TO GET THEM OFF THE GROUND, A LONG-TERM STRATEGIC PLAN WOULD BE NEEDED

Michele De Carli*, Marco Marigo*, Laura Carnieletto* and Filippo Busato**

**Università Mercatorum Roma. Presidente AiCARR

In 2007, the 4th Assessment Report (chapter “The physical science basis”) of the IPCC (Intergovernmental Panel on Climate Change) established the anthropogenic responsibility of climate change due to the accumulation of CO2 in the atmosphere.

A few years later, Figure 1 appeared, “the figure that changed everything…” (Macchi, 2022), which illustrates with disarming evidence how the concentration of carbon dioxide in the atmosphere has increased indisputably (observe the last section, which is almost vertical) due to human activities and the development of energy demand that resulted after the industrial revolution. The need for decarbonisation is therefore not one of the possible scenarios, it is an imperative. To the environmental aspect, which is far from negligible as it could cause objective difficulties for humankind (starting from the agri-food sector), the geopolitical factor has recently been added, with a war that threatens, among other things, the security and the conditions of supply of natural gas in our country. From these considerations comes an investigative stimulus on the contribution of heat pumps in the residential sector to the decarbonisation of Italy. This analysis, which is addressed to our nation and cannot and should not be generalised, has

fallen into the specificity of gas consumption in the residential sector and the climatic and urbanisation variety of the peninsula, which must be taken into account in the interpretation of the most suitable plant solutions in the different areas.

NATURAL GAS CONSUMPTION FOR RESIDENTIAL HEATING

Natural gas consumption in the residential sector is 19.7 billion cubic metres (ARERA Source) [1]. The use made of gas at the residential level is about 80% for heating needs, while the remaining 20% can be considered divided between domestic hot water production and cooking food.

On the basis of regional gas consumption for distribution networks and taking into account climatic conditions, gas consumption was distributed at regional level. In this way, it was possible to find an indicative value of gas consumption per building, also taking into account the ISTAT data of population, residential area and average household composition [2]. The gas values, broken down regionally and by residential unit, are shown in Figure 2 in terms of specific energy.

FIGURE 1. Evolution of CO2 concentration in the atmosphere

FIGURE 2. Average specific energy demand for average accommodation in the different regions (Sardinia is not present as it does not have a natural gas distribution network)

HEAT PUMPS FOR HEATING: STATE OF THE ART

High-temperature heat pumps normally use the R134a fluid (Figure 3) which allows for greater temperature differences between evaporation and condensation than the R410A fluid normally used for medium and low-temperature plant terminals. Given the low heat demand in climate zone B and the low incidence of radiator installations in this area, it can be assumed that heat can be supplied by direct expansion or medium and low temperature machines. In climates C, D, E and F, on the other hand, it is assumed that systems with existing radiators and boilers are present. In these cases, for a high-temperature heat pump (usually with a scroll compressor) it could be possible to work at a limit of 70 °C of delivery temperature for the radiator system with 0 °C of external temperature. This temperature would therefore make it possible to meet energy requirements of up to 0 °C in all climatic zones. In climatic zones C and D, therefore, it is possible to cover all the energy needs required by the building by means of a high-temperature heat pump (as highlighted for a sample building shown in Figure 4 In climatic zones E and F, it may be possible to cover the energy requirement of the building by means of a high-temperature heat pump up to 0 °C for climatic zone E and up to -1 °C for climatic zone F (as highlighted for a sample building shown in Figure 5). Under these conditions, based on some work carried out on different archetypes, it can be said that it covers about 87% of the energy needs for a climatic zone E, while it reaches 72% of the total winter thermal needs in a climatic zone F, assuming that it works cautiously in alternating operation.

INTENSIVE USE OF HEAT PUMPS IN RESIDENTIAL HEATING: SOLUTIONS FOR DIFFERENT CLIMATES

Taking into account the coverage of heating needs with the above values, an analysis was carried out to verify the coverage for heating in the different regions. This first analysis did not consider the possibility of generating

FIGURE 5. Average power required by the building (solid line) and average power provided by a heat pump (dotted line) that meets the thermal peak under 0 °C design conditions for climatic zone E (green) and F (blue)

domestic hot water with the heat pump, nor the effect of the introduction of induction plans on decarbonisation at national level. The result achieved led to a 72% reduction in gas in the residential sector, corresponding to 14.2 billion Nm3 of gas. The result is very relevant because climatic zones F weigh less than other climatic zones representing areas with less population than other climatic zones. Considering an average COP of 2.8 for heat pumps, it would mean a reduction of 87 TWh of final energy (-64% of energy), 25 TWh (-18%) of primary energy, 48 TWh of non-renewable primary energy (-34%). This result means an increase in electricity consumption of 48.6 GWh, which is 17% more than the Italian electricity production of 2020 (280 TWh). With regard to costs, considering 0.86 €/Nm3 of gas and 0.25 €/kW, the conversion from boilers to heat pump would not lead to a significant difference in costs. However, the conversion from natural gas to heat pump would lead to an 18.7% reduction in natural gas in Italy, resulting in less dependence on states with reduced political stability.

A POSSIBLE FIVE-YEAR PLAN

The average installable power per housing is about 3.3 kW, which would result in a maximum installable power of 33 GW of installable thermal power. Assuming a cost of €2,000/kW for the heat pump alone and €1,500/kW for the installation, this would mean €67 billion for the production of heat pumps and €50 billion of finance directed to the plumbing sector and manufacturers. Considering the current turnover of the heat pump sector (€2.5 billion), this means that if you want to achieve the installation of heat pumps throughout the residential sector you would need to quintuple the current production of heat pumps, a goal that could be achieved if there was the political will to do so. To this end, it is necessary to think about different incentive options for the installation of these products, as well as the production and supply of standardised systems facilitating the design (of machines and the thermotechnical planner) and the installation of production systems. The plumbing sector today counts for about €20 billion, therefore the installation should not be a problem, although it is also necessary in this case to increase the manpower for this sector.

DECARBONISATION AND REDUCTION OF DEPENDENCE ON NATURAL GAS: RESULTS IN THE MEDIUM TO LONG TERM

If the prospect of decarbonisation sees a decisive contribution in the adoption of heat pumps as a generation system, it must be framed within a slower process, but with which synergy is created, of energy requalification of buildings. In addition to stimulating demand, however, it is also necessary to consider the industrial and productive aspects for which it is necessary, as is being done for renewables, to launch ambitious and long-term policies.

SMART HOME THERMOREGULATION

NEW GENERATION OF HEAT PUMPS WITH R290

The completely natural refrigerant R290 is environmentally friendly due to its GWP index of 3, and thus guarantees almost zero impact on the propagation of greenhouses gases. The use of the natural refrigerant R290 allows the generation of hot water with temperatures up to 75 °C and guarantees excellent energy efficiency levels. Thanks to the MAXA control system, the entire range can generate hot water for winter heating, cold water for summer cooling, and domestic hot water for both residential and commercial applications. The range includes three different heat pumps; in fact we will have, the group dedicated to residential applications with powers ranging from 6 to 18 Kw; the group dedicated to commercial installations with the range from 19 to 28 kW and finally the larger size group with powers of 40 and 50 kW. www.maxa.it

NOBILI BRINGS THE SUN TO ISH

Nobili will present the prototype of the “Sole” mixer designed by Diego Giromini based on the archetype of the tube with a knob that recalls industrial plumbing closures. “Sole” mixer engages at the base of the sink and curves gently forward into the spout: a unicum made possible by the most innovative mixing cartridge ever, Nobili Widd® 2020. Thinned and efficient it impacts on the cleanliness of the lines but also on efficiency and durability because it works dry: water does not come into contact with the ceramic discs and other moving parts. A novelty also on the energy-saving front thanks to the opening on the cold water position, which prevents

the boiler from switching on unintentionally and wasting gas. A retractable aerator limits the consumption of “Sole” to 5 l/min (against the normal 9/11 lt min of the competitors) while maintaining a pleasant and full-bodied water jet. Also new at the fair will be the Sorgente multi-function faucet line with 3 models: Filtra, developed in collaboration with Austria’s BWT, marking the company’s official entry into the filtered water sector; Bolle for dispensing boiling water and Frizza for sparkling water. All integrate the latest generation of solutions developed by Nobili to ensure water efficiency and wholesomeness. www.nobili.it

SELF-CLEANING MAGNETIC SLUDGE REMOVER FILTER for heating pumps

MP1 by RBM ensures effective collection of impurities in the system, collecting particles from corrosion and fouling processes and preventing them from circulating. It is advised to install MP1 on the return circuit, at the inlet of the heating pump, in order to protect it from any impurities in the system, especially during the start-up phase.

MP1 removes any magnetic and non-magnetic particles that may cause damage to the system. The continuous

passage of the fluid through the filter during the normal operation of the system on which it is installed, gradually removes any dirt.

GREAT NEWS REGARDS VENTILATION

The innovative AriaSilent system by Valsir – for the air distribution in a Heat Recovery Ventilation system – is one the news displayed at ISH. Among its main features there is the unprecedented versatility of the jointing system AriaSilent Link, which allows to match different corrugated conduits with the same distribution box and plenum, regardless the type of conduit used. This means minimizing the number of parts needed for the whole system. Moreover, AriaSilent components are made of plastics with an antibacterial feature, for a superior comfort level and for a higher hygienic degree. Many patents have been developed for this product: in the distribution boxes for instance, the inner flap distributes air evenly to every conduit, the tear-off tabs that allow to use only the connections actually needed and avoid caps and a safe hooking system of the grilles. But there are further great news regarding the Heat Recovery Ventilation units. During the exhibition we will present the latest generation of our units: improved efficiency and performances, an easier installation. www.valsir.it

DRIVING INCLUSIVE AND GREEN URBAN TRANSITIONS

A new Horizon Europe project led by IIASA called Urban ReLeaf leverages citizen science for public sector innovation

Urban ReLeaf aims to co-create citizen-powered data ecosystems to support climate change adaptation, green infrastructure, and urban design planning. The project, coordinated by Inian Moorthy and Gerid Hager from the IIASA Novel Data Ecosystems for Sustainability (NODES) Research Group, is a collaboration between academic and private sector partners as well as six cities: Athens, Greece; Cascais, Portugal; Dundee, UK; Mannheim, Germany; Riga, Latvia; and Utrecht, The Netherlands.

By 2050, it is expected that 83.7% of Europe’s population will live in cities, a marked increase from the estimated 72% in 2015. While cities provide opportunities and infrastructure, city-dwellers also face threats such as harmful levels of air pollution and the heat island effect, which is becoming increasingly severe due to climate change.

Nature-based solutions such as the expansion of urban greenspace and

by IIASA

tree planting can provide cooling effects, decrease air pollution, and improve mental health, among other benefits. Several initiatives support this approach, for example the New EU Forest Strategy for 2030 and the European Green Deal. However, informed decision making is still a challenge for public authorities due to the lack of reliable data. Citizen science along with other novel data streams like Earth Observation, lowcost sensor networks, and wearable technologies can offer new insights to address this challenge.

“We are excited to work with urban authorities, opening a new chapter for citizen participation and the uptake of citizens’ observations – says Gerid Hager. With a mission-led approach, Urban ReLeaf builds new partnerships and processes where citizens collaborate alongside authorities to share knowledge and drive targeted and evidence-based decision making”.

THE GLOBAL ENERGY CRISIS IS DRIVING A SURGE IN HEAT PUMPS

Sales set to hit new records, helping save energy and emissions, but policy action is needed to unblock bottlenecks such as upfront costs and training workers

Worldwide sales of heat pumps are set to soar to record levels in the coming years as the global energy crisis accelerates their adoption, the International Energy Agency says in the report “The Future of Heat Pumps” The heat pump market has been growing strongly in recent years, due to falling costs and strong incentives. Global heat pump sales rose by nearly 15% in 2021, double the average of the past decade, led by the European Union where they rose by around 35%. Sales in 2022 are set to hit record levels in response to the global energy crisis, especially in Europe where some countries are seeing sales double in the first half of 2022 compared with the same period last year. Annual sales of heat pumps in the EU could rise to 7 million by 2030 – up from 2 million in 2021 – if governments succeed in hitting their emissions reduction and energy security goals. Heating buildings accounts for one-third of EU gas demand today. Heat pumps could reduce that demand by nearly 7 billion cubic metres (bcm) in 2025 – roughly equal to the natural gas supplied via the Trans Adriatic Pipeline in 2021. This annual gas saving would grow to at least 21 bcm by 2030 if EU climate targets are met. “Heat pumps are an indispensable part of any plan to cut emissions and natural gas use, and an urgent priority in the European Union today –said IEA Executive Director Fatih Birol. The technology is tried and tested, even in the coldest of climates. Policy makers should be putting their weight behind this technology that is witnessing unprecedented momentum at the moment”. Heat pumps typically cost less over their lifetimes than fossil fuel boilers, thanks to their higher efficiency. At today’s energy prices, annual energy bill savings for households that switch to heat pumps can range from USD 300 in the United States to USD 900 in Europe. Government policy support is needed, though, to help consumers overcome heat pumps’ higher upfront costs relative to alternatives. The costs of purchasing and installing a heat pump can be two-to-four times as much as those for a gas boiler. Financial incentives for heat pumps are already available in over 30 countries, which together cover more than 70% of heating demand today. Many of them also provide additional support to low-income households where energy savings from a heat pump can be significant, ranging between 2% and 6% of household income. In a scenario in which all

by IEA

governments achieve their energy and climate pledges in full, heat pumps become the main way of decarbonising space and water heating worldwide. The IEA estimates heat pumps have the potential to reduce global carbon dioxide (CO2) emissions by at least 500 million tonnes in 2030 – equal to the annual CO2 emissions of all cars in Europe today. Leading manufacturers are seeing promising signs that today’s momentum and policy support could put the industry on a trajectory that triples sales by 2030 – and they have accordingly announced plans to invest more than USD 4 billion in expanding heat pump production and related efforts, mostly in Europe. Opportunities exist also for heat pumps to provide low-temperature heat in industrial sectors, especially in the paper, food and chemicals industries. In Europe alone, 15 gigawatts of heat pumps could be installed across 3.000 facilities in these three sectors, which have been hit hard by recent rises in natural gas prices. The rapid expansion of heat pumps presents some challenges, but the report highlights solutions to these barriers. Heat pumps will inevitably increase electricity demand, though energy efficiency can greatly reduce the impacts on the grid, alongside improved grid planning. Global heat pump supply and installation could require over 1.3 million workers by 2030, nearly triple the current amount, raising the potential for skilled labour shortages, especially for installers. Special training programmes and the inclusion of heat pumps in certifications for plumbers and electrical engineers could help avoid the risk of shortages in skilled labour. The additional global upfront investment in heat pumps required to reach announced climate pledges reaches USD 160 billion annually by 2030. However, these costs are outweighed by the economy-wide savings on fuel, especially if energy prices remain close to their current levels. “All the pieces are in place for the heat pump market to take off, reminiscent of the trajectory we have seen in other key climate technologies like solar PV and electric vehicles – said Dr Birol. Heat pumps address many of policy makers’ most pressing concerns on energy affordability, supply security and the climate crisis. Policy measures are in place today, but they need to be reinforced urgently to allow heat pumps fulfil their significant economic and environmental potential”.
