The direct electrification of uses appears to be the most relevant solution to decarbonising the economy. In sectors where it is difficult (or even impossible), use of low-carbon hydrogen will be a key driver for achieving carbon neutrality. This is the EDF Group's strong belief.

Did you say low-carbon hydrogen?

Hydrogen is a form of energy, a fuel, but also a raw material for many heavy industries such as refining, chemicals, glass, etc. Today, about 95%(1) of hydrogen is produced from fossil fuels. The process is therefore a major emitter of CO₂: to produce 1 kg of hydrogen, more than 10 kg of CO₂ are emitted.
Yet there is a way to produce hydrogen that emits a lot less CO₂: by water electrolysis, provided that the electricity used in the process is itself decarbonised. This is the case for 97% of the electricity produced in France by EDF. It is this technology that the EDF Group has chosen to rely on to produce 100% low-carbon hydrogen (≤ 3kg of CO₂ per kg of hydrogen produced).

With the Hydrogen Plan, EDF is accelerating the in-depth decarbonisation of the sectors that emit the most CO₂.

Use of decarbonised hydrogen, what's the idea?

Where direct electrification of uses is still technologically difficult, if not impossible, or not economically profitable, use of decarbonised hydrogen can play a key role in achieving carbon neutrality. This is particularly the case for certain heavy industries (chemicals, refining, steel, etc.) as well as for maritime and air transport, for which e-fuels (synthetic fuels derived from electrolytic hydrogen) are a very promising way of decarbonisation. The number of projects is increasing; sustainable public support at national and European level is gradually being established. These are two strong signals that make it possible to make this future market a reality, estimated by the International Energy Agency to be worth nearly 500 Mt/year by 2050.(1)

What are the uses for decarbonised hydrogen?

EDF considers it relevant to massively expand the use of decarbonised hydrogen in industry now, to prepare for future uses in heavy transport (maritime and air) and, more in the long term, the flexibility of electrical networks.

  • Replacing fossil hydrogen with decarbonised hydrogen in industries using hydrogen as a feedstock is the main decarbonisation solution identified for these industries: ammonia and methanol production, hydrocarbon refining and steel industry.

  • Today, local mobility projects (powering bus fleets, refuse collection vehicles, trucks) with a few MW of electrolysis have already been established in France. In the longer term, the most significant opportunities will very probably be related to the use of e-fuels, synthetic fuels derived from hydrogen (e-ammonia, e-methanol or e-kerosene) in maritime transport and aviation.

  • L’hydrogène électrolytique pourrait à terme constituer une option pour la décarbonation de la production d’électricité dans les pays disposant de peu de moyens décarbonés pilotables ou dans les petits systèmes électriques isolés.

Decarbonised hydrogen and EDF... quite a story!

To achieve its ambition, EDF can rely on its long-standing expertise in electrolytic hydrogen. The first R&D work was undertaken as early as the 1970s and electrolytic hydrogen is at the heart of the expertise developed through its research institute in Germany Eifer (European Institute for Energy Research) since 2003. On the operational side, in 2018 EDF acquired a stake in the French electrolyser manufacturer McPhy to strengthen the Group's industrial expertise. Since 2019, Hynamics, a wholly owned subsidiary of the EDF Group, has been offering 100% low-carbon electrolytic hydrogen production and supply in France and Europe.
