Europe’s energy storage boom stalled last year due to a slowdown in large-scale schemes designed to store clean electricity from major renewable energy projects, according to the European Association for Storage of Energy (Ease).
A new study by consultants Delta-EE for Ease found that the European market grew by a total of 1 gigawatts per hour in 2019, a significant slowdown compared with 2018, when the energy storage market exceeded expectations to grow by 1.47GWh.
The slowdown in 2019 has emerged amid rising concern that the outbreak of the coronavirus may stall the rollout of clean energy technologies in 2020, dealing a double blow to the clean energy industry.
The 2019 downturn was particularly marked for large-scale energy storage projects which connect directly to energy grids, and can help make better use of renewable energy by storing the clean electricity to use when wind and solar power is not available.
These large, utility-scale projects often require planning permission, government financial support or procurement tenders to move ahead. Meanwhile, the rollout of home battery kits, which relies far less on policy support, remained a fast-growing market.
Patrick Clerens, the Ease secretary general , said: “The message is clear: even if energy storage is a key enabler of the energy transition and clearly seen as a major tool to achieve the emissions targets linked to the Paris agreement, more support is needed.”
