Reversible Fuel Cell System Powerbox

  • Electrolysis and fuel cell principles in one device that can be placed inside
  • Hydrogen storage in high pressure storage tanks, placed outside
  • The system is designed to convert electrical renewable energy (solar/wind) or energy from play-the-grid mode, into green hydrogen (electrolysis process) that can later be converted again into electricity and heat (fuel cell process)
  • All the Solenco Power products have a CE declaration and are in conformity with the essential requirements for hydrogen systems and hydrogen storage.
  • With our dashboard, the customer can constantly follow up on the performance of the box, the hydrogen level, pressure, water temperature, energy consumption etc. Projected yearly savings can be monitored.

Working principle

  • Electricity needs are covered by the solar panels during day time and only the surplus is sent to the SPB™ to be stored as hydrogen. When there’s no sunshine, electricity, and heat are produced by the SPB™ from the stored hydrogen.
  • Hydrogen can be stored for days, but also for months or even entire seasons.
