Thermal-power cycles operating with super critical carbon dioxide (sCO2) nearing commercialization and are positioned to have a large role in the power generation systems in the rapidly evolving clean energy grids. Much of the associated risks have been eliminated or...

While Li-ion batteries will likely dominate immediacy requirements for Grid-support, intermediate and long term time shifting of energy will have to transition to new technologies. Currently batteries are viable for up to 4 hrs of discharge, but this will reduce over...

Process Description The earliest variant of the PTT cycle, shown in Figure 1, is characterized by a symbiotic interaction between an air-Brayton cycle and a sCO2 Brayton cycle. The air discharged by the air-cycle compressor serves as a recuperation medium and is...

Current supercritical carbon dioxide Brayton cycles are recuperated cycles because of the large amount of heat left after expansion through the turbine. The high level of efficiency of SCO2 cycles is largely owing to the use of recuperators to recapture this heat....
