Alternatives to CAES that provide arbitrage, balancing, ancillary, stability and other services include Demand Side Response (DSR), power stations, pumped hydro-electric stations, batteries, interconnectors and

The role hydrogen plays will be significant in zero-carbon economies in the future. To achieve all this, electrolysis needs to get much cheaper and higher

Storelectric’s CAES plants are usually designed as stand-alone plants with stand-alone profits based on buying electricity from the grid and selling it back to the

Adiabatic and isothermal CAES are two different processes which sometimes get confused. The way each process treats heat during the compression and expansion processes is

Reports have claimed that baseload power is not necessary in Europe, only grid flexibility. The basis for this thinking is Germany, which has achieved moments

The Energy Transition The energy transition to a zero-carbon economy is, quite correctly, seeing widespread roll-out of tens of GW of renewable generation. We’re already

CAES or Batteries: Which is Better? Many people have suggested that batteries are a viable way forward for grid-scale electricity storage, and some have cast

As renewables are more widely adopted, how will they change utility companies’ business models? It depends which utility companies: those involved in generation, transmission/distribution, or

What would a decarbonised energy system look like? There is no single answer or “magic bullet”, no “winning technology” for powering the world: a decarbonised

Decarbonisation by 2040, where a country is run by 100% renewable energy, is a target for energy systems. If achieved by 2030, then so much
