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.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.Commissioned in 1966, Total's Grandpuits-Bailly-Carrois refinery was for a long time the only refinery in the Paris region. In September 2020, TotalEnergies launched a project to convert the site, in line with its strategy to become carbon neutral by 2050. This zero-crude project, with a total investment of more than 500 million euros, is based on the development of several future-oriented activities in the field of biomass, renewable energies, and circular economy: chemical recycling of plastic waste, production of biosourced and biodegradable bioplastics, production of sustainable aviation fuels, construction of a solar farm and electricity storage by batteries. The start-up of these new units will begin in 2022, and they should all be operational by 2025.
