Meet our selection of invited companies for Japan Energy Challenge 2019

LONDON, 31 July 2019 – After a long scouting, selection, and due diligence process, the 2019 class of Japan Energy Challenge has been selected. 

Japan Energy Challenge provides a series of energy innovation programmes aimed at helping international energy sector companies demonstrate their products with their first major customer in Japan – the world’s most dynamic and exciting energy market. While our activities are ongoing, our central event is our annual Venture Competition and, launched this year, Startup Pitch Competition.

We selected this year’s cohort by identifying the most promising trends in the cleantech sector and matching them according to their strategic fit with the sponsors’ goals and Japanese market projections. More than 600 innovative companies active within these trends were evaluated during the selection process, until a pool of promising companies were identified. 

We targeted primarily European companies and shortlisted them based on market traction, technology demonstration and project runway times. Depending on their size, traction, technology readiness level, and timeframe for a perspective collaboration, the companies were considered for either the Venture Competition – where a collaboration can be expected within one year of meeting the sponsor – or the Startup Pitch Competition – where we the goal is to showcase early stage innovation that may have future application in Japan. 

Once the invitation to take part in the program was accepted, the companies underwent a due diligence process led by the JEC team over a period of several months. Opportunities were identified and, and having explored each company remotely the sponsors and companies will now have a chance to meet face-to-face to discuss future projects. The companies that make the most progress in these discussions or present the most compelling pitch for investigating further will win a prize – a fully-sponsored trip to Japan to meet again and sign agreements.
