Abstract: Energy can be stored by directing fluid into an expandable receptacle that has a relatively heavy mass above it. The fluid fills the receptacle such that it expands and lifts up the heavy mass above it. At a time when energy is needed, the fluid can be allowed to flow out of the receptacle and through a turbine or hydraulic motor to generate power or electricity. Intermittent or unreliable sources of power can be used to fill the receptacle, or power from a power grid can be used to fill the receptacle at times that are off-peak. During peak-load times, the potential energy of the fluid in the receptacle can be converted to power. The receptacle can also be used to control water flows and can provide a source of power and potable water to a community.

Abstract: A method and arrangement are proposed for injecting CO2 into a subterranean aquifer for storage therein. In order to reduce the effects of water evaporation from brine in the aquifer when dry CO2 is injected into the aquifer, the CO2 is supplied mixed with a salt-lean fluid, i.e. a fluid that contains a low concentration of ions that can precipitate out as salts. The mixing may take place at the wellhead, with the CO2 salt-lean fluids supplied via separate low-grade material pipelines. The proportion of CO2 and salt-lean fluid in the mixture is such as to obtain a CO2 composition that is saturated with salt-lean fluid at the site of injection into the aquifer. By injecting saturated or “wet” CO2, less water is evaporated from the brine and the salt precipitation is greatly reduced, so keeping the pore spaces clear and providing an increased accessible pore volume for CO2 storage.

Abstract: A water detention system comprises a sub-base of crushed rock or stone overlying an impermeable layer which may be naturally-occurring, as in an impermeable sub-grade, or may be formed by an impermeable membrane laid over the sub-grade prior to the sub-base layer.

Abstract: A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern.

This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal.
