The European Association for Storage of Energy (EASE) is calling for policymakers to break the barriers that hamper the uptake of storage in Europe’s transport sector.

In a newly-published position paper, EASE explains how it believes the role of stationary storage can enable “a rapid and effective transition to a decarbonized transport sector”.

EASE argues that by coupling the energy and transport sectors, energy storage technologies can play an important role in reducing the costs of widespread electric vehicle roll-outs and also “relieve the stress that would be placed on the electricity system as a result, while enabling the transition to a decarbonized transport sector”.

EASE has found that the role of energy storage in this context is often not highlighted and understood, despite sustainable mobility becoming a hot European topic, especially with the ongoing discussions on the 2050 Long-Term Strategy for GHG Emissions Reductions.

In its paper, EASE identifies several barriers, including the lack of provisions in the EU regulatory framework that explicitly enable electric vehicle batteries to be repurposed for second use applications.

It also spotlights economic roadblocks such as energy tariffs, pricing structures or barriers to access energy and ancillary markets, which prevent a wider roll-out of storage for charging infrastructure and the provision of vehicle-to-grid services.

EASE states that “overcoming these barriers would empower three different use cases for energy storage and transport, thereby providing unique and diverse benefits for consumers, market players developing charging infrastructure, system operators, and the broader energy system”.

The three different use cases are repurposing EV batteries to give them a second life in other applications; Deploying stationary energy storage to support (fast) charging infrastructures; and facilitating vehicle-to-grid integration through smart charging and vehicle-to-grid services.

Energy storage and decarbonizing transport will be key topics at European Utility Week in Paris later this year.
