An integral part of the transition to green energy is sensibly utilizing the occasional surplus electricity generated by renewable sources. One possibility is using such surplus energy to produce hydrogen via electrolysis. This green hydrogen can then either serve as an energy carrier itself or be used in further synthesis reactions.
One possible example of such a reaction entails using carbon dioxide to produce methane, which would also help reduce CO2 emissions. The methane can then in turn be used as a replacement for natural gas. However, there are some technical challenges along the way. For example, the reaction releases a lot of heat, which can cause problems.
