The SOFC systems can already be operated with eco-friendly biogas or natural gas – and are already hydrogen-compatible for the energy system of the future. For cities and conurbations with high energy requirements, SOFC systems can ensure sustainable power supplies – with zero emissions of nitrogen oxides, particulates, and CO2.

SOFC is an energy exchange device which can directly convert the chemical energy of fuel and oxidant into electrical energy through an electrochemical

Mitsubishi Power''s latest innovation in this space came in the form of a solid oxide fuel cell (SOFC) called MEGAMIE.

Conversely, thermal power plants require significant amounts of water for cooling. In fact, the number one use of water in the U.S. is for cooling power plants. To produce one megawatt per hour for a year, thermoelectric power generation for the U.S. grid withdraws approximately 156 million gallons of water more than our platform.

Overall, the use of DME with T RF = 300 C yields higher power output, whereas the power output of the methanol fuelled SOFC-MGT power plant does not practically depend on T RF.
