FAQS about Hot lava energy storage in power plants

Can stored heat be used to power a power plant?

Stored heat can be added to existing cycles. Finally, it can offer a second life for power plants. The system would replace generation, drawing electricity from the local grid or renewable sources, while using the existing steam cycle and operation processes.

Can volcanic rocks store energy?

John Kosowatz is senior editor. A large electrothermal energy storage project in Hamburg, Germany, uses heated volcanic rocks to store energy. Siemens Gamesa, the company behind the pilot project, says it’s a cost-effective and scalable solution to store renewable energy.

How does a hot air storage system work?

The project uses 1,000 tonnes of volcanic rock as the storage medium. Electrical energy is converted into hot air through a resistance heater and blower, heating the rock to 650 C. When demand peaks, the system’s steam turbine reconverts the energy into electricity.

Could a decommissioned thermal power plant be a viable alternative?

Decommissioned conventional thermal power plants could house such energy storage units, replacing the furnace and using existing equipment. This ETES can be a commercially viable alternative to pumped-storage hydropower and batteries, according to Siemens Gamesa.

How does a volcanic rock storage system work?

The system uses crushed volcanic rock weighing 1,000 tonnes as a storage medium. The stones are kept in a thermally insulated container and heated to 750 degrees Celsius with a resistance heater and a blower powered by electricity from the grid. During peak demand, the hot air inside is converted back to electricity by a conventional steam turbine.
