Huntorf’s CAES has 290MW capacity with around 40% of efficiency. The plant includes one 290 MW turbine, 60 MW compressor, and two reservoirs which are called caverns. The CAES has significant merits including a practical solution for large/small scale, low-cost, and long lifetime.
One of the main technical barriers is related to the topological properties of the deployment location. Topology is associated with assessing the geometrical properties of the ground. It has a direct relationship with the increase in the capital expenditure of deploying plant.
The two caverns have been placed in around 240 meters depth under the ground and the pipelines which are used to sending and releasing air from close to 198-meter depth. These two caverns have an approximate volume of 310,000 m3.
it runs on a daily cycle with 8 hours of compressed air charging and 2 hours of operation at a rated power of 290 MW. This plant provides black-start power to nuclear power plants, back-up to local power systems and extra electrical power to fill the gap between the electricity generation and demand.
A black start is a process of restoring partially or completely shut down power plants to power generation without relying on the external electric power transmission network.
