  • the remaining hydrogen is available for power generation by gas and steam turbines.
  • the exhaust gas that leaves the power plant in the end is therefore virtually CO2-free.
  • the combustion gas energy losses are reduced due to the elimination of the ballast content of the air nitrogen in the combustion gas, and thirdly, the nitrogen oxide emissions caused by the air nitrogen are avoided.
