Normal combined cycle gas plants vent excess heat into the air and lose 40pc of the energy. NET Power is a closed loop. All is conserved. Mr Allam discovered the concept in the obscure notes of a group of Russian scientists working in the 1930. They were nearly all killed in World War Two. The plant relies on an ‘oxy-combustion’ system that burns natural gas with pure oxygen rather than with air. The twist is that it harnesses carbon dioxide itself as a fuel. This CO2 circulates constantly in a supercritical state, generating a s urplus that is drained away in usable form for industry.
