About us

Company details


Empowering generations with clean energy forever, is the vision of Nel. Our technology allows people and businesses to make everyday use of hydrogen, the most abundant element in the universe.

Our business

Nel is a global, dedicated hydrogen company, delivering optimal solutions to produce, store and distribute hydrogen from renewable energy. We serve industries, energy and gas companies with leading hydrogen technology. Since its foundation in 1927, Nel has a proud history of development and continual improvement of hydrogen plants. Our hydrogen solutions cover the entire value chain from hydrogen production technologies to manufacturing of hydrogen fueling stations, providing all fuel cell electric vehicles with the same fast fueling and long range as conventional vehicles today.


Why we believe renewable hydrogen will be number 1 in the future:

  • The world needs a new energy carrier to replace oil and gas
  • Hydrogen is the element with the highest energy density
  • Through electrolysis hydrogen can be produced from water and renewable energy
  • Access to renewable energy is practically infinite
  • The electric grids do not have the capacity to handle the entire future energy demand alone
  • The demand for stable energy supply diverge from the fluctuating nature of renewable energy production in general
  • Large scale introduction of renewable energy is dependent on energy storage solutions
