What is a battery energy storage system?
A battery energy storage system (BESS) plays a vital role in balancing renewable energy’s intermittency during peaks of demand for electricity. It stores excess energy generated by sources such as solar power and wind during periods of low demand and releases it when needed — ensuring grid stability and preventing outages.
Why should we invest in battery energy storage systems?
As the world continues to invest in clean, resilient energy systems, BESS will remain at the forefront, helping to build a more sustainable future for everyone. Despite its benefits, deploying battery energy storage systems presents several challenges. A key issue is battery degradation over time, particularly for lithium-ion batteries.
Why is battery storage important?
As we shift toward clean energy, battery storage systems have become key to integrating renewables into the grid. 1 By smoothing out the energy supply from intermittent renewable sources, BESS enhances grid reliability, reduces reliance on fossil fuels and helps lower carbon emissions, making it a crucial player in the energy transition.
How much energy will be stored in a battery system?
Looking ahead, a sixfold increase in global energy storage capacity is needed by 2030, with 1,200 GW expected to come from battery systems, to meet climate and energy goals. 8 Reducing emissions: BESS optimises the use of renewables by storing excess energy, reducing the need for fossil fuel power generation.
