Finland-based energy startup Granarium Technologies has secured more than €1.0 million in pre-seed funding to commercialize a breakthrough renewable supercapacitor technology designed to support grid stability and industrial power reliability.
The funding round was led by BSV Ventures, with participation from Beamline, FiBAN, EstBAN, and LatBAN.
The company, a spin-off from VTT Technical Research Centre of Finland, has also received the transfer of the underlying technology and intellectual property from VTT.
Granarium’s patented technology uses nanocellulose and biocarbon derived from waste wood and agricultural residues to produce renewable supercapacitors that can store and release electricity rapidly.
The company says the technology offers a safer, more sustainable alternative to conventional energy storage systems while reducing production costs by up to 80%.
