Neil Crumpton, FoE UK - Zero

Friends of the Earth EW&NIUK CCS updateCopenhagen22nd Oct 2009Neil CrumptonEnergy specialist / anti-nuclearcampaigner


CCS ‘competition : launched March 2007 - closedMarch 20081.6 GW post-C ‘Kingsnorth’ scheme entered E.onPaul Goldby CEO :“By making it clear we will use our proposed Kingsnorth site todevelop CCS technology, we are addressing one of thefundamental issues in the whole debate:how can we demonstrate that carbon capture works on acommercial scale unless we first build a station which isCCS-ready and then fit the technology to that station ? “


June 2008• Government announces CCR consultation +selection four bidders pre-qualified post-CSpring 2009* Hatfield 900 MW CCGT ( IGCC ) applicationconsented (CCS part 2 ?)* Minister Miliband : ‘no more unabated coal’* proposes up to 4 x 300 MW demonstrationschemes - Treasury funds limited


June - September 2009• Government announces coal consultation• Oct 2009 (last week)• E.on withdraws its Kingsnorth proposal !• seen by NGOs as campaign ‘win’• Hatfield 900 MW CCGT could receive EUfunding…..


August 2009Underground Coal Gasification (UCG)scheme proposed Firth of Forth* access to massive coal resources soenergy security potential* near Longannet coal power stationso possibility of using shared pipeline* supported in principle from FOE


October 2009 (last week)E.On withdraws Kingsnorth proposal !Government still considering its position


UK energy supply 2008 :primary supply 2,700 / final demand 1,900 TWh/year


UK needs to radically change is energy supplysources and infrastructure -• global climate change / chaos• oil and gas sources running outFriends of the Earth advise renewable energy +Combined Heat & Power (CHP) + E Efficiency+ Carbon Capture & Storage (CCS) ‘in transition’nuclear power - a dangerous distraction


UK energy sector in figures :Primary Energy Supply 2,700 TWh/yearPower station losses 400 TWh/yearFinal Energy Demand 2007 1,900 TWh/yearElectricity 400 TWh/yearGas to homes 400 TWh/yearTransport 700 TWh/year‘replacement’ nuclear 10 GW 80 TWh/year‘ambitious’ nuclear 30 GW 240 TWh/year2020 EU ‘15%’ RE target ~ 240 TWh/year


Electricity Grid 30 – 50 GW daily variation- by 2040 larger variation but in heat/ transport


Lights going out in 2016 ?• first new nuclear station 2018 at earliest* 9 GW of new gas power stations CCGT’s* 1 GWe of industrial CHP recently consented+ 7 GWe further potential (total 15 GWe)* renewables 15% EU 2020 target ? GW* 2 – 5 GW of CCS demo schemes by 2020Yes, but an increasing UK energy securityissue by 2020 - high % of Russian gas ?


UK energy security :• methane imports high by 2020• methane running out by 2040• methane also emits carbon dioxide• convert gas power stations to run onhydrogen from CCS coal / biomass gasifiers+ possibly underground coal gasification+ alkaline fuel cells ( hydrogen )= British coal / biomass with near zero CO2* Uranium – has to be imported


North Sea gas pipelines : CCS CO2 in future +hydrogen pipelines onshore - gasifier site topower station ( turbines, fuel cells )


Final energy demand 2050 : 1,100 - 1,400 TWh/y ?RE scale-up without CCS over 1,100 TWh/y wouldbe increasingly expensive - option for CCS orSaharan imports (CSP and wind)


RES + CCS/CHP a scenario :(about 15 GWe industrial 200 TWh/y + up to 17GWe district heating 200 TWh/y)


UK final energy demand 2050 - a scenario :1,100 – 1,400 TWh/year (up to 400 CCS / CHP)wind: 450 - 600 ( 50 onshore)wave : 50+tidal : 25 - 75 (not Severn barrage)biomass : 25 (mostly CHP)solar PV : 50+ (thermal – see*)heat pumps * : 200 - 300 (COP 2–3 most buildings)geothermal : 0 - 10 ?CSP imports : 0 - 140 (up to 10 % - optional)CCS coal CHP : up to 300 – 400 (if needed)Imports : Supergrid + solar liquids, goods, biomass ?


A new role for Combined Heat & Power (CHP) ?• traditional - utilises power station reject hotwater > CHP 80 % efficient• new ? – cost-effective combination with heatpumps and solar thermal ? > storage / flexibility


About 50 % of Denmark’s electricity comesfrom CHP / district heating (heat grids)


Solar district heating > community heat pumps ?• Denmark, Marstal - 8,000 m 2 solar array in field& Copenhagen - 3,000 m 2 roofs (95 Centigrade)• Austria, Graz - 3,500 m 2 arrays on large roofs• Stockholm - 260 MW sea water heat pumps


London ‘heat map’ – up to city-wideheat grids ? eg Odense in Denmark


Barking gas power station (CCGT)• 1 GW of electricity to the grid – enough ‘turbine’heat for 350,000 homes dumped into the Thames• heat from CCS power stations > valuable low-C


Friends of the Earth Cymru• UK has significant renewable resources -especially marine (wind, tides, waves)+ heat pumps + solar thermal (possibly via urbanheat grids + storage)• heat stores / HVDC / chemicals address variability• CCS - security, low-carbon, load-following& offers ‘carbon-negative’ capability• no need for nuclear - proliferation benefit -peacemaking leadership, no new waste


A renewably powered UK and world is achievable- global nuclear currently 3 % and not needed• concentrated solar power (CSP) - Earth’s biggestrenewable resource - 1% of deserts 1/5th ofcurrent global energy (18,000 TWh/y)• renewables + CCS coal avoids proliferation,terrorism (Israel - Iran) and new ‘hotter’ nuclearwaste – with no tried or tested storage route• UK should develop CCS technologies notshowcase nuclear technologies
