Coal conversion
Phasing out the use of coal in electricity generation is a key factor in tackling climate change. Turning existing coal-fired power plants into renewable energy hubs by means of molten salt storages is one way of doing so.
Benefits
- Scalable grid-based energy storage
- Supports the green transition
- Creates balance between supply and demand
- Improved system flexibility
- Optimized efficiency
Scalable grid-based energy storage
A molten salt storage can be used as a scalable grid-based energy storage. Excess electricity is stored in molten salt during periods of surplus in the grid and discharged, when the supply is low and the demand high. The fossil fuel boiler will be replaced by two molten salt tanks. The salt has a temperature of up to 565º C and will be used for generating steam for operating a turbine which in the end will generate electricity.
Recycling of existing infrastructure
A large part of the existing infrastructure can be re-used. This includes e.g., the steam turbine, generators, condensing heat exchangers and water treatment equipment as well as high value components for switching, transforming, and transmitting high voltage power. To facilitate a complete replacement of a coal-fired boiler unit, an electric molten salt heater and two molten salt storage tanks with integrated steam generation systems must be installed.
