Based on the technological developments and experiments conducted in recent years, we can conclude that hydrogen will contribute to the energy and ecological transition in four major ways:
- Hydrogen offers solutions for improved, more flexible power grids ;
- The storage options made possible by hydrogen technology offer new opportunities for self-consumption within a building, a city block or a small community ;
- Onboard hydrogen offers new solutions for electric transportation ;
- The industry is currently using more than 900,000 tonnes of hydrogen per year, produced from fossil fuels; that represents 7.5% of the greenhouse-gas emissions attributable to French industry. The challenge is to improve existing processes and replace fossil-fuel hydrogen with hydrogen from renewable resources whenever possible.
