Utilization of CO2 as cushion gas for porous media compressed air energy storage …
The large increase in density of CO 2 around its critical pressure at near‐critical temperature means that a PM‐CAES reservoir operated around the CO 2 critical pressure could potentially store more air (energy) for a given pressure rise in the reservoir. One‐dimensional (1D) radial TOUGH2 simulations of PM‐CAES with CO 2 as the …
Choice of hydrogen energy storage in salt caverns and
Alternatives are natural gas storage and compressed hydrogen energy storage (CHES). For single energy storage systems of 100 GWh or more, only these two chemical energy storage-based techniques presently have technological capability (Fig. 1) [4], [5], [6]. Due to the harm fossil fuel usage has done to the environment, the demand …

Theory of rotationally symmetric air cushion vehicle
My attempt at a theory is here: Air Cushion Vehicle Theory To begin with, I am interested in the relationship between vehicle weight W and air cushion thickness t. What I come up with is W = const1 - const2/t^2. That says that once a certain threshold thickness has been exceeded, the weight that the disc can carry increases with thickness …
Compressed air energy storage with liquid air capacity extension
Compressed Air Energy Storage (CAES) at large scales, with effective management of heat, is recognised to have potential to provide affordable grid-scale energy storage. Where suitable geologies are unavailable, compressed air could be stored in pressurised steel tanks above ground, but this would incur significant storage costs.
