Europe’s energy crisis shows no signs of easing. With imports from Russia drastically reduced, industrial electricity prices soared 124% between 2019 and 2023 in the UK and 93% in France. In the UK, the average annual household bill will hit £1,755 from October 1st, a £35 hike from the previous cap set three months ago, while small businesses face mounting pressure from skyrocketing costs.
But amid the turmoil, a new wave of energy startups is stepping up. These companies are not only helping to cushion the immediate blow but are also laying the groundwork for a cleaner, more resilient and secure energy system in Europe.
From renewable generation (solar, wind, nuclear) to efficiency solutions in buildings, heating and cooling, to breakthroughs in storage, green hydrogen and heat pumps — these are the startups shaping Europe’s energy future, according to investors from Planet A Ventures, Blume Equity, Voyager Ventures, Kompas VC and Extantia Capital.
