EIT InnoEnergy
Welcome to EIT InnoEnergy EIT InnoEnergy is the innovation engine for sustainable energy across Europe supported by the European Institute of Innovation and Technology. For us, true sustainability also means an industry that’s commercially viable, endlessly innovative, and highly competitive. We make this possible by helping Europe adopt pioneering new technologies, without risk or complexity. From mobility to construction - from renewable energy sources to smarter storage solutions - our commercially-attractive technologies are the product of a trusted ecosystem for sustainable energy. We’ve invested 275.5 million euros into more than 480 assets, which have forecasted sales amounting to 5.3 billion euros. In addition, 1,100 alumni have graduated from our Master's and PhD School programmes, many of whom work for prestigious companies such as Tesla, Siemens, Total and Procter & Gamble. We also bring together 500+ key players from across the energy value chain, from 18 different countries, who have indirect access to 150 million energy consumers. The result is the proven, landmark innovation you need to reduce energy costs, increase system performance, decrease greenhouse gas (GHG) emissions, create jobs, and increase competitiveness. It’s a reflection of our reputation for delivering practical innovation and, above all else, supporting the industry as it undergoes transformation for the future.
