3 FAQs about [Construction of a new energy storage project in Aarhus Denmark]
Can a new energy storage technology store green energy in water?
In collaboration with the entrepreneurial company AquaNamic, Aarhus University will now start construction of a 100 sqm demonstration facility for new energy storage technology that can store green energy in water.
Why do storage projects have surpluses?
Because maximum generation can occur at both high and low demand, surpluses are much less certain and also highly variable. That tends to stretch storage projects beyond viability when attempting anything more than short term output smoothing and grid stabilisation..
Can energy storage back up unreliable power generation?
The basic concept of backing up unreliable power generation with energy storage is going to be uneconomical, unreliable, or both. In some places, it can be cloudy for weeks at a time. This is the point. They claim to be able to store the energy for weeks. I’m dubious, but if true, it may be effective. – up to about a week.
