Ergosup, a French cleantech startup founded in 2012, develops and commercializes solutions for the production and storage of green hydrogen using its own patented electrolysis technology. The company has developed HyRiS products, which are green hydrogen refueling stations for hydrogen e-drones and e-bikes, as well as a low-cost hydrogen supply solution for laboratories and small industries.
Challenges: hydrogen fuel
Hydrogen is the cleanest and most efficient energy-generating fuel, making it particularly useful for applications involving automobiles, ships, and aircraft. The use of hydrogen in the context of clean transportation requires the ability to store hydrogen at high pressures ranging from 200 to 700 bar in tanks on board transportation.
Currently hydrogen production is dominated by the steam reforming of natural gas due to its low cost. However, steam reforming releases carbon dioxide. The electrolysis of water with electrolyzers can produce green hydrogen if their power source is coupled to the renewable energy sources. Currently, the hydrogen pressures at the outlet of the electrolyzer do not exceed 80 bar, which is a minimum to be reached in order for large-scale applications in the field of transportation to be conceivable. The conventional method involves compressing the gas with a mechanical compressor, which is costly and requires frequent maintenance.
Hydrogen may be produced at large industrial plants, compressed, and then transported to distribution stations, or may be produced directly at the distribution station. Logistics-wise, on-site production is particularly advantageous.
It would be interesting from an ecological standpoint if this hydrogen production were conducted locally and centrally by electrolysis, without further compression by mechanical compressor.
Ergosup Technology
Ergosup develops electrolyzers that directly produce very highly pressurized hydrogen (over 80 bar) in a decoupled manner.
