As a part of the change towards higher usage renewable energy sources, which naturally deliver intermittently, need for storage systems is increasing. For compensation disturbance in power production due to inter-day seasonal weather changes, long-term required. In spectrum systems, one out few geographically independent possibilities use heat store electricity, so-called Carnot-batteries. This...

As an essential component of the SCO2 recompression Brayton cycle, recuperator has a significant impact on efficiency and stability entire cycle system. The printed circuit heat exchanger (PCHE) is most suitable for in cycle. To investigate effects structural parameters asymmetric airfoil fins thermo-hydraulic performance PCHEs, simplified three-dimensional numerical simulation models PCHE with...

A novel liquefied natural gas (LNG) fueled power plant is proposed, which has virtually zero CO2 and other emissions and a high efficiency. Natural gas is fired in highly enriched oxygen and recycled CO2 flue gas. The plant operates in a quasi-combined cycle mode with a supercritical CO2 Rankine-like cycle and a CO2 Brayton cycle, interconnected by the heat transfer process in the recuperation ...
