To demonstrate the feasibility of capture of CO2 and production of H2 in an IGCC that uses solid fossil fuels and wastes as main feedstock.
To obtain economic data enough to scale it to the full Puertollano IGCC capacity in synthetic gas production.
Project of pilot plant in existing IGCC of Puertollano is part of a Spanish national initiative, “Advanced technologies of CO2 conversion, capture and storage” and it is coordinated with other related projects:
Project # 2 is to explore CO2 capture with oxyfuel technology in a 20MW pilot plant. To be built in El Bierzo, NW of Spain (coordinator CIUDEN)
Project # 3 is to study and regulate geological storage in Spain (coordinator IGME)
Project #4 is to study public awareness of CCS technologies (coordinator CIEMAT)

5. CONCLUSIONS
IPCC Unless greenhouse gas emissions are cut by 50-80% by 2050 (especially CO2), the impact of global warming will be disastrous.
World energy demand Expected to double by 2050.
So We must act fast using a portfolio of solutions (mainly, energy efficiency improvement, renewables and CCS) to reduce CO2 emissions in the requiredmassive scale.
IGCC technology can contribute to this aim because:
Existing IGCC plants are an opportunity to develop cleaner electricity with fossil fuels
Diversification of fossil fuels use according to the reserves and total life cycle is absolutely necessary
Clean co-production of H2 and electricity is possible and can be adapted to market demand
Massive H2 production is currently possible and technology is available
