Top 10 Clean Energy Startups

Our top 10 clean energy startups are Enpal, Ecoflow, Freyr Energy, EHGroup, Moment Energy, Purpose Energy, Piclo, Common Energy, Liquid Wind & Rebel Energy

In a turbulent period for the energy industry, an opportunity arises for new ideas, new technologies and new companies to take a place in the future of energy. Public sector support to help start-ups get new clean energy technologies to the market has risen sharply since the Paris Agreement was signed in 2015, reports the International Energy Agency.
Almost half of the emissions the world needs to avoid to achieve net zero emissions by 2050 cannot be tackled with technologies on the market today. Rather, cutting these emissions will require technologies that are still at the demonstration or prototype stage, mostly in sectors such as heavy industry and long-distance transport. Our top 10 clean energy startups are working to be the leaders of tomorrow, cutting those emissions, and driving the energy transition to the clean energy future of tomorrow.

10. Rebel Energy

CEO: Dan Bates

Founded in 2017, UK based Rebel Energy is working to end fuel poverty in the UK on a foundation of renewable energy including wind, solar and hydro.
