Granarium raises €1M+ to commercialise renewable supercapacitors for grid stability

**Granarium Technologies Secures Over €1 Million to Revolutionize Grid Stability with Renewable Supercapacitors** Finnish deeptech startup Granarium Technologies has successfully raised over €1 million in Pre-Seed funding, signaling significant investor confidence in its innovative approach to grid stability. The funding, co-led by BSV Ventures and Beamline, with contributions from FiBAN, EstBAN, and LatBAN, will be instrumental in commercializing the company's proprietary renewable supercapacitor technology, which spun out from VTT. This development arrives at a critical juncture as Europe grapples with increasing grid volatility, driven by the transition to renewable energy sources and stricter EU resilience mandates. Granarium's groundbreaking technology utilizes a nanocellulose-based material platform to bind biocarbon structures for power storage, promising up to an 80% reduction in production capital expenditure. This sustainable and locally producible system is designed to offer fast-response power storage, addressing the growing demand for grid balancing, frequency response, and industrial power quality. The supercapacitors, capable of upcycling waste materials, complement existing battery technologies by managing short-duration power needs and peak loads, thereby enhancing overall energy system efficiency and reliability. The implications of Granarium's technology extend to bolstering European digital sovereignty by reducing reliance on critical raw materials and fostering local, resilient energy infrastructure. By enabling simple production using locally sourced materials, the company's self-sufficient solution bypasses complex logistics chains, aligning with the EU's strategic goals for energy independence. With pilot customers and value chain partners already secured, Granarium is poised to launch its first pilots within six months, aiming for initial commercial production at a small industrial scale and subsequent international market expansion.
