EUROBAT, a trade organisation representing European Automotive and Industrial Battery Manufacturers, welcomed the European Commission initiative, saying one of the key conditions for its success will be to develop a coherent regulatory framework.
One example cited by EUROBAT is "the legislative overlap" that exists between the Battery Directive, End-of-Life Vehicles Directive and the REACH Regulation on chemical safety.
"A variety of battery chemistries and technologies exists today: lead, lithium, sodium and nickel batteries. They all answer to different demands in terms of performance, capabilities and applications," EUROBAT said, calling for "further development of all existing and new battery technologies without jeopardizing or even banning them".
Coinciding with the Commission's initiative, the European Association for Storage of Energy (EASE) published an update of its energy storage technology roadmap, a document drawn up with the European Energy Research Alliance (EERA), an EU-funded body which coordinates a massive public research effort to develop more efficient and cheaper low carbon energy technologies.
The 120-pages long document provides an overview of all existing energy storage technologies with a focus on stationary applications, and draws recommendations related to policy and research activities in Europe. Energy storage for electro mobility is also considered.
"EASE and EERA consider that a wide range of energy storage technologies will be needed to address the challenges of the energy transition," EASE and EERA write in their report, which identifies cost reduction as "the most important goal" for each type of technology.
"Another overarching theme is the need to research energy storage business cases and to clarify the technical requirements and economics of aggregating different energy storage services," the two organisations write.
