IMDEA Conference at GENERA + MATELEC 2025
Master Battery calls for simplification of regulations to boost energy storage
Madrid, 25 November 2025. Master Battery participated in the conference ‘Storage and conversion for manageable renewable energy’ organised by IMDEA Energy as part of the International Week of Electrification and Decarbonisation - GENERA 2025.
Master Battery's CTO, Miguel Manjón, took part in the panel discussion to warn of the impact that current energy storage regulations are having on the development of large projects: ‘The technology needed to develop these projects is now fully mature and continues to advance at a rapid pace. However, the main obstacle is not technical, but regulatory.’
Manjón stressed that ‘the absence of a clear regulatory framework, coupled with complex administrative procedures and delays in granting permits for large facilities, is causing uncertainty and delays. This situation increases uncertainty when it comes to mobilising financing and accessing subsidies, thus hindering the effective deployment of new investments’.
Other speakers agreed on the need to introduce regulatory changes to alleviate the ‘regulatory bottleneck’ and facilitate the deployment of key projects for the energy transition.
The session was moderated by Jesús Palma, deputy director of IMDEA Energy, who highlighted the positive aspects of the Ciudadenergía initiative, promoted by Master Battery in Móstoles.
Conference proceedings
The conference analysed the key technologies for achieving manageable renewable energy, focusing on solutions such as wind-solar hybridisation, battery energy storage and green hydrogen, all of which are essential for reducing costs and increasing the share of clean energy in the electricity system. The meeting brought together R&D specialists, manufacturers, integrators and end users from sectors such as automotive, industry and electrical and thermal storage.
The event kicked off with a presentation of the SOLENER-CM project by Marina Villegas, Director General of Research and Technological Innovation for the Community of Madrid, who explained the objectives of transforming the regional energy system into a more sustainable, efficient and affordable model. Jadra Mosa, programme coordinator and scientist at the CSIC, elaborated on its progress and lines of work.
The panel included representatives from the scientific and business ecosystem —including H2Greem Global Solutions, IMDEA Energy and the UPM— who discussed new hybrid storage technologies, the integration and backup of renewables in the grid and the role of green hydrogen. They also analysed the future of energy storage, where electrochemical storage will continue to play a leading role, with lithium still at the forefront but with growing interest in alternative materials such as sodium.
Master Battery researches sodium batteries
In this context, Miguel Manjón announced the work ‘State-of-the-art analysis of industrial developments and characterisation of sodium batteries’, which is being carried out by the Master Battery Chair - Polytechnic University of Madrid.
The interest in sodium batteries stems from the fact that, unlike lithium—which is scarce and expensive because it is concentrated in a few countries—sodium is an abundant and easily accessible resource. This makes it a more sustainable alternative with less supply risk, which explains its growing attention in the energy sector.
However, Manjón stressed that, despite its appeal, sodium technology still presents challenges to be overcome: ‘It looks like a solution for the future, but at present it is not mature enough for use in large-scale storage.’
