Hydrogen, an emission-free gas, can play a key role in achieving the European and global decarbonisation targets by 2050
Hydrogen is a gas that has been used in industry for decades. Being the most abundant element in the universe, it can play a key role in ensuring the achievement of European and global decarbonisation targets by 2050: the hydrogen molecule does not contain carbon atoms and its use does not generate emissions of climate-changing gases, which would be harmful to humans and environment.
As highlighted by a study commissioned to Navigant by the “Gas for Climate” Consortium, most hydrogen in Europe will initially consist of the so-called "blue" hydrogen, the carbon-neutral hydrogen produced from natural gas through the carbon capture and storage (CCS). During the energy transition towards a completely decarbonised system, this type of hydrogen will be able to play a "bridge role" to achieve faster reductions in global carbon dioxide emissions. Blue hydrogen will then be gradually replaced by green hydrogen, produced (by electrolysis) from renewable sources such as wind and solar power, so achieving a fully renewable and sustainable energy mix. Green hydrogen will allow these non-programmable resources to benefit from the widespread gas transportation and storage network, enabling electric-gas sector coupling solutions and thus helping to meet the challenge of intermittency. According to the Gas for Climate study, by 2050 the potential for producing green hydrogen from renewable electricity in excess could reach 200 TWh (equivalent to 19 billion cubic meters of natural gas).
