Gas turbine air inlet cooling + ice energy storage
In 2017, 30% of U.S. electricity was generated from natural gas power plants, an increase of 20% from 2011. The increase in electricity generation from natural gas is one of the primary drivers for decreasing carbon footprint of the power grid. Gas turbines, especially on hot summer days, will pre-cool the air before combustion to increase their power output.
Ice energy storage provides gas power plants new peaking capabilities
How? Efficient ice energy storage can help complement gas power plants by linking them to renewable power generation. When the sun is shining or wind is blowing, excess power can be used to make ice for the natural gas plant. Later, that ice can be used to pre-cool the air used by the gas turbine, increasing the power output of the plant by up to 35%!
