Process flow diagram for indirect-fired Brayton cycles for coal and natural gas.

•  Applicable to advanced combustion boilers
•  >50% cycle efficiency (work out/heat in) possible
•  High fluid density, low pressure ratio enable compact turbomachinery
•  Ideally suited to constant temperature heat source
•  Adaptable for dry cooling

Direct-fired process includes combustor, turbine, recuperator, water separator, compressor, cooler and CO2 storage.

•  Applicable to coal gasification or natural gas
•  Fuel flexible: coal syngas and natural gas
•  95% CO2 capture at storage pressure
•  Net water producer, if dry-cooled
