A hybrid Liquid Air Energy Storage (LAES) system is being developed to respond to grid frequency events within one second.
The system – designed and developed in the UK by Highview Power Storage – has been awarded funding of GBP1.5 million ($1.9m) from Innovate UK, the UK’s innovation agency.
The UK government’s sudden interest in battery technology became a little clearer last week. If the country meets its commitment to phase out all petrol and diesel vehicles by 2040, it could need the equivalent of six nuclear power plants to charge all the electric vehicles.
The UK National Grid’s solution, outlined in its ‘Future Energy Scenarios’ report (published last month), is smart charging which, it says, could substantially decrease the pressure on the system at peak times, reducing additional demand from electric vehicles to 3.5GW by 2030 from a potential scenario of 8GW of extra demand.
A wind farm in the Irish Sea is integrating a 2MW battery system.
The first-of-its-kind wind power and battery hybrid system at an offshore wind farm is to provide frequency response to the UK grid.
