The 22nd World Hydrogen Energy Conference is in Rio de Janeiro from 18-21 June. E4tech Director David Hart will join fellow experts from around the world to assess progress and look forward. He'll be busy - presentations on the fuel cell and electrolyser industries, a plenary talk on Hydrogen Roadmapping, and plenary roundtables on energy systems models and on transportation. But he'd love to see you and catch up, if you're there. For more information about E4tech’s work in the fuel cells and hydrogen sector, click here.
