This week has seen Carbon Brief publish analyses of the Department of Energy, Business and Industrial Strategy (BEIS) energy use. The subsequent news reports have been focused on the UK’s collapsing coal industry and the consequent impact on the environment. It has been reported that the use of coal fell by a record 50% in 2016, principally as a result of increased domestic carbon taxes. The result, a drop in carbon emissions to 19th century lows. To provide some perspective, UK windfarms generated more power than coal in 2016 – a real feat for the renewable energy industry. However, even with the decline it has been suggested that carbon emissions were still 381 million tonnes.
As more gas and coal plants are decommissioned, the reliance on renewable energy sources such as solar and wind power is increasing. Energy storage technology will play a crucial role in the management of the demand for energy supplies in the UK and will contribute vastly to the reduction of the UK’s carbon emissions.
Store it or lose it
Fundamentally, countries worldwide are actively making steps towards creating more energy efficient and yet cleaner cities. The UK is placing energy storage at the heart of its new Modern Industrial Strategy, due to its potential to support smart energy systems and the automotive sector. As the energy industry moves away from carbon-heavy production, the twin-approach of renewable energy and storage will be critical for delivering on the demand while securing the future of UK energy.
Energy storage has a central role to play in creating a new, evolved UK energy system and will make a significant contribution to decarbonising our energy supply as a whole. Falling costs of battery technology and the new opportunities opening up in this market mean that there is an ever-growing business case for investment in this area.
Storage systems can fulfil multiple roles within the energy market. Energy can be stored when prices are low and used on site when they are high to save consumers and businesses money on their bills. Given the potential of energy storage to stabilise energy supply during periods of high and low demand, suppliers and consumers would be ill-advised to ignore its significance.
Storage enables more renewable energy sources to be integrated into the UK’s overall power supply. This is in addition to helping to balance energy supply and demand more effectively and increasing energy security for an evolving power network.
The National Grid has made a significant move towards a future that embraces energy storage. By committing to support battery storage on a large scale, the increased investment will mean a reliable source of real-time energy to balance the entire grid.
