6 FAQs about [Luxembourg cryogenic energy storage system]
What is cryogenic energy storage?
Cryogenic energy storage (CES) is the use of low temperature (cryogenic) liquids such as liquid air or liquid nitrogen to store energy. The technology is primarily used for the large-scale storage of electricity.
What is stored liquid cryogen?
Stored liquid cryogen is capable of providing part of the refrigerating demand in large storage warehouses or food factories, being thereby heated for the purposes of power generation.
How long does a cryogenic energy storage system last?
The design was based on research by the Birmingham Centre for Cryogenic Energy Storage (BCCES) associated with the University of Birmingham, and has storage for up to 15 MWh, and can generate a peak supply of 5 MW (so when fully charged lasts for three hours at maximum output) and is designed for an operational life of 40 years.
What is CES Energy Storage?
CES is a known but still rather underdeveloped energy storage principle, where excessive or renewable power is used to liquefy and store a cryogenic gas. This liquid cryogen is then pumped and boiled at low temperatures to run turbines and produce electricity for either on-site use or feeding the power grid during peak demand periods.
Where should a cryogenic plant be located?
To achieve the greatest efficiencies, a cryogenic plant should be located near a source of low-grade heat which would otherwise be lost to the atmosphere. Often this would be a thermal power station that could be expected to be also generating electricity at times of peak demand and the highest prices.
How efficient is a cold storage system?
In isolation, the process is only 25% efficient. This is increased to around 50% when used with a low-grade cold store, such as a large gravel bed, to capture the cold generated by evaporating the cryogen. The cold is re-used during the next refrigeration cycle.
