Wind and solar power will have an increasing role in electric production. Due to their own nature, they cannot be scheduled. Energy storage will become a priority to balance production and request. Power to Gas places itself inside the electricity infrastructure: a flexible element for the energy storage.
Hydrogen produced due to the electricity overproduction can be injected in the grid being previously mixed with natural gas thanks to the blending solutions, guaranteeing the compliance with network management specifications.
Thanks to methanogen organisms, hydrogen can be alternately combined with CO2 and transformed in methane, ready for the injection into the grid: an efficient way to store energy and in the same time intercept CO2 emissions.
