Deep Tech plays a key role in decarbonizing the economy. In the energy sector, some technologies are now mostly mature and need only commercial scaling as most wind and solar energy, while technological breakthroughs are still strongly needed in energy storage, hydrogen, nuclear energy and much more. We classified 180+ pushing the boundary of energy tech in Europe These novel energy startups in Europe raised $1.6B in 2022, almost 50% more than the 2021 total and 3x compared to 2020. Hydrogen startups have raised the most funding in 2022, followed by nuclear fission, new battery chemistries & supercapacitors. Segments covered in the landscape include next-gen batteries (solid state, new chemistries, physical enhancements) and innovative large-scale energy storage (flow batteries, salt storage, kinetic etc), hydrogen tech, waste heat recovery & energy harvesting, novel wind energy (bladeless, innovative materials), Novel solar tech (curve, transparent, materials), nuclear fusion & fission, heating & cooling (e.g. heat pumps), thermal energy storage and much more.
