Press Release

EIT InnoEnergy’s student start-up, ReLi, wins the first edition of the Battle of Green Talent!


Since November 2020, 250 students from EIT InnoEnergy Master School and partner business schools have been competing in the Battle of Green Talent, an online entrepreneurial game which came to a conclusion on April 8th 2021. The goal of the Battle of Green Talent was to immerse students in a world of entrepreneurial, innovative thinking, assisted by virtual investors and experienced advisors.


This resulted in 25 sustainable start-ups, created by EIT InnoEnergy Master’s students competing for a spot in the final and the main prize to receive real cash funding of €10 000 and a chance to enter the EIT InnoEnergy student incubator services with a starting fee of €5 000. The winning investor, a role played by MBA students from ESADE Business School, London Business School, Grenoble École de Management and Nyenrode Business Universiteit, took home a prize of €10 000 in cash and a €5 000 travel and expense budget for The Business Booster, EIT InnoEnergy’s yearly state-of-the-art business event.


On April 8th 2021, during the online final event, 6 finalist teams got a chance to show their start-up pitch video and participate in a short Q&A with the audience. After careful deliberation by the EIT InnoEnergy jury, the winning team and the winning investor were chosen and revealed. Also, during the event, the audience could vote for their favourite team, which took home an original public’s favourite award!


The winning start-up of the 2021 edition of the Battle of Green Talent is team ReLi. They plan to manufacture sustainable and affordable energy storage solutions for solar PV homeowners by upcycling retired EV batteries. The team consists of Laura Laringe (Master’s in Smart Electrical Networks and Systems), Krishna Kumar Rathinam (Master’s in Smart Electrical Networks and Systems), Emilia Chojkiewicz (Master’s in Smart Electrical Networks and Systems), Ashish Baskar (Master’s in Sustainable Energy Systems), Mateusz Sierakowski (Master’s in Energy Storage) and Wojciech Godlewski (Master’s in Energy Storage).
