Lengshui beishan reservoir energy storage
As 41 % of China's CO2 emission comes from coastal provinces and cities, permanent sequestration of anthropogenic CO2 in offshore sediments is a priority to achieve China's national goal of net zero by 2060. I. [PDF Version]FAQS about Lengshui beishan reservoir energy storage
How a reservoir can be used to store energy?
A reservoir made in a porous and permeable underground formation can be used to store Natural Gas, CO 2, Air, Hydrogen or even Thermal Energy. Storage of an energy carrying fluid requires a phase of compression and injection in gaseous state into the reservoir: the free-phase gas pushes the formation water away from the injection wells.
What should be considered when evaluating large-scale underground energy storage reservoirs?
Thermal and thermodynamics properties and behaviour of the rocks should also be considered as part of the studies developed when evaluating large-scale underground energy storage reservoirs.
Can a geological reservoir be used as a storage technology?
After identification of the existing geological reservoirs, the feasibility of adopting a specific storage technology will be a function of a techno-economic analysis. Understanding which factors will influence more this techno-economic analysis will vary with the storage technology.
