When a CHP plant is combined with heat storage, the possibility to transition to green hydrogen with gas turbines such as the SGT-700 and SGT-800 enables further decarbonization of thermal energy use and at the same time provides renewable balancing power to the grid to allow a large share of wind and solar, he said.
Interest in hydrogen energy can be traced back to the 1800 century, but it got a keen interest in 1970 due to the severe oil crises [4], [5], [6].
