We invite start-ups and SMEs to submit their ideas for digital solutions for clean energy challenges from leading companies. Deadline for submissions is 28 September. Selected start-ups/SMEs will be invited to the Clean Energy Hackathon, held in Linz/Austria on 14-15 November (they will receive a travel voucher). The Hackathon is part of the Urbantech project, an EU funded initiative, which offers up to 54,000 Euro to selected start-ups/SMEs in different funding stages. In addition, they will contribute to energy security and climate neutrality!
