A concept of coal-fired power plant built around a supercritical CO2 Brayton power cycle and 90% post-combustion CO2 capture have been designed. The power cycle has been adapted to the coal-fired boiler thermal output, this boiler has been roughly designed in order to assess the power cycle...

In this paper, a new approach of converting renewable electricity into methane via syngas (a mixture of CO and H2) and CO methanation is presented. Surplus of electricity is used to electrolyze H2O and CO2 to H2 and CO by using a SOEC (Solid Oxide Electrolysis Cell). Syngas produced is then...
