de o s a o o e ec o ogyConsequence of shelving of Janschwalde Project means that Europe could lose
grounds in the development of oxyfuel combustion

Concluding Remarks - ChinaConcluding Remarks China• Success to demonstrate oxyfuel
combustion technology in China would require the following:q g• Cost effective CCS technology • Reliable CO2 Storage• Reliable CO2 Storage • Outside funding for project execution • Special power tariff / EOR or other utilisation
schemes • MOST endorsement of CCS capture technology
and storage technology
