Air Liquide and TotalEnergies are innovating, in the context of the conversion to a biorefinery of the TotalEnergies’ Grandpuits site, to produce and valorize renewable and low-carbon hydrogen. Under a long-term contract, committing TotalEnergies to purchase the hydrogen produced for the needs of its platform, Air Liquide will invest over 130 million euros in the construction and operation of a new unit producing hydrogen. This unit will partly use biogas from the biorefinery built by TotalEnergies, and will be delivered with Air Liquide’s carbon capture technology, CryocapTM. These innovations will prevent emissions amounting to 150,000 tonnes of CO2 a year compared to current processes. TotalEnergies’ biorefinery will use the unit’s hydrogen to produce sustainable aviation fuel.
In line with the two companies’ shared ambition to reach carbon neutrality by 2050, this project is based on an innovative sustainable and circular approach:
Air Liquide will build and operate at the Grandpuits site a new hydrogen production unit with an annual capacity of more than 20,000 tonnes. By recycling, in part, residual biogases from Grandpuits’ biorefinery as a substitute for the natural gas traditionally used, the hydrogen produced by this unit will be partly renewable.
In addition, this unit will include, from its start-up, an Air Liquide Cryocap™ H2 carbon capture unit. This will enable to capture, for reuse in agri-food and industrial applications, over 110,000 tonnes of CO2 per year contributing to reducing the site’s carbon footprint.
Most of the renewable and low-carbon hydrogen produced will be used by the biorefinery to produce sustainable aviation fuel. This hydrogen could also be used to support sustainable mobility in the Ile-de-France region.
Pascal Vinet, Senior Vice President and a member of Air Liquide’s Executive Committee, supervising notably Europe Industries activities, said : "This innovative project is characterized by the combination of several solutions in order to produce renewable and low-carbon hydrogen, and contribute to the decarbonization of TotalEnergies’ Grandpuits site. It also provides the opportunity to recycle CO2 as part of a circular economy approach while securing its supply for agri-food applications. This project illustrates Air Liquide’s expertise in working with its customers on customized solutions to help them reduce their carbon footprint and actively participate in the fight against global warming. It provides yet another example of the key role that hydrogen will play to succeed in the energy transition".
"By recycling the biogas produced by the biorefinery into renewable hydrogen, this innovative project makes full use of the conversion of the Grandpuits refinery into a zero crude platform harnessing the potential of biomass, especially in the production of sustainable aviation fuel,” said Bernard Pinatel, President, Refining & Chemicals, TotalEnergies."Combined with the production of low carbon hydrogen and the capture of CO2, this project contributes to TotalEnergies’ ambition to decarbonize all of the hydrogen used by its European refineries by 2030."
