Granarium Technologies raised €1 million in pre-seed funding led by BSV Ventures. The startup uses nanocellulose from wood pulp to make supercapacitors that store energy in milliseconds. Devices charge and discharge faster than lithium batteries and cut production costs by up to 80% compared to conventional methods.
A Fraunhofer ISI study finds that weakening EU EV targets by 49 million fewer EVs by 2040 would require building 150 equivalent power plants. Fewer EVs reduce vehicle-to-grid storage, leading to 37% less solar PV installed at -51 GW between 2025 and 2040. The study shows reduced grid flexibility harms renewable energy integration and increases grid balancing costs.
