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

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.
