DIMES DISTRIBUTED INTEGRATED MULTI-VECTOR ENERGY SYSTEM
Dr Seema Dave & Beth Dawson Innova2on & research 28th November 2017
Challenges that shaped the Project • Mee2ng increasing energy demand (both in power and transport with increasing EVs)
• Grid restric2ons • Clean Energy Supply and climate change targets
Why Hydrogen and Fuel Cells? Hydrogen is an excellent energy carrier. It’s not a primary energy source but can be used to store, transport and provide energy. Its energy density is high per unit mass. One of the advantages of hydrogen is that it can store energy from all sources, both renewable, fossil and even nuclear power – it’s very flexible. Hydrogen is very likely to play a key role in the necessary transi2on from fossil fuels to a sustainable energy system.

DIMES DISTRIBUTED INTEGRATED MULTI-VECTOR ENERGY SYSTEM
Energy
Biogas
Natural gas
• H2 Generated from organic waste • Using chemical process, H2 is separated out from N gas
Hydrogen fuel-‐cell
Heat
Hydrogen
• Island type independent energy network • Solve grid constraint issues • Heat generated is captured from the process & use for domes2c purposes
• Use as a energy storage • For transport as a fuel
Creates Sustainable -‐ resilient energy system, integrated within the urban systems
DIMES: System Configurations
Project Context • 12 Month Feasibility Project at Bicester Phase 2 developments • Won £60,000 funding for this study from Innovate UK’s ‘CiJes Integrated by Design’ compeJJon • Demonstrate “Island” based electrical system using mul2-‐ MW Fuel Cell Systems • Follow-‐on project expected in 2018-‐19 in Oxfordshire
& Metropolitan Infrastructure Limited are DIME partners
Expected Project outcomes

•
local organic waste sustainable recycling system-‐ reducing landfill sites pressure
•
Rapid InstallaJon Jme, Easy to stack up the capacity in same amount of Space
•
Energy resilient sustainable system
DIMES : Challenges Developer Engagement The environmental creden2als + Fuel & Energy Efficiency + Storage costs savings+ Heat Network integra2on+ Old grid infrastructure upgrade costs savings + Island type grid network-‐ grid connec2on costs savings Energy Resiliency will definitely stack up,
Will the figures add up?
DIMES : Early outcomes Report based upon the Himley Village development by P3Eco: 1700 residenJal units, plus 14,478m2 of commercial properJes. Scenario 3: the ‘today’s best in class’ approach 2 x CHP gas engine (1 large, 1 small) (with gas boiler back up) 9,461 kWth total capacity Local genera2on has beher efficiency and CO2 savings above central genera2on (-‐1342 tonnes CO2 per annum against regulated baseline) 30 year IRR of 15% -‐ with standard developer contribu2ons Good net cashflow
DIMES : Early outcomes Scenario 1: the ‘fuel cell only’ approach 2 x large sta2onary fuel cell CHP units (with gas boiler back up) 10,800 kWth total capacity Most expensive to install and run Lowest CO2 and other emissions (-‐2424 tonnes CO2 per annum against regulated baseline) Op2on for island-‐power Op2on for hydrogen for transport 30 year IRR of 15% -‐ with higher developer contribu2ons Poor net cash flow
Relative Emissions
DIMES : Early outcomes Scenario 2: the ‘jigsaw’ or ‘Goldilocks’ approach 2 x medium sta2onary fuel cell CHP units 2 x CHP gas engine (1 large, 1 small) (with gas boiler back up) 9,676 kWth total capacity Approx 40% more expensive to install and run Lower CO2 and other emissions (-‐1744 tonnes CO2 per annum against regulated baseline) Op2on for island-‐power 30 year IRR of 15% -‐ with increased developer contribu2ons Small effect on net cashflow
DIMES : Lessons Learnt Urban energy systems are undergoing a drama2c transforma2on. Ci2es must take ac2on on carbon emissions, adapt to a new reality, and plan intelligently for the future. There is a need for new collabora2on models in the sector, and u2li2es must start thinking outside of the box. Technology alone will not solve a problem. However, by bringing together a pornolio of innova2ve tools into integrated solu2ons, we can create powerful outcomes and Local Authori2es can play a big role in this change to happen.
