Ground source heat pumps work by extracting heat from the ground, which can then be used in the home for space heating or hot water.

Geothermal power involves harnessing the heat trapped within the Earth’s crust. This heat is used to convert water to steam that can drive turbines.

CHP cogeneration makes electricity & heat in one single process. Find out more about its uses in industry, district heating & power generation.

Spare Electricity within the grid is used to compress and store air under pressure, which can then be released on demand to make electricity.
