Electricity explained Energy storage for electricity generation
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
Hydrogen in power generation
At the moment, hydrogen is the most promising candidate of the P2X fuel for power plants. Hydrogen is carbon-free, has the highest production energy efficiency of the P2X fuels and with time it is predicted to become the most cost competitive due to low renewable electricity prices. Of course, there are several issues still to be tackled.
