ELYSE ENERGY, a pioneer in low-carbon fuels: green hydrogen and e-fuels
Elyse Energy, founded in 2020, is a pioneer in the production of low-carbon fuels, focusing on the development, design, construction, and operation of green hydrogen and e-fuel plants.
In 2022, Elyse Energy launched two ambitious projects for the production of sustainable fuels:
- BioTJet: a project to produce e-biokerosene to help decarbonize air travel (SAF, Sustainable Aviation Fuel - Sustainable Aviation Fuel (SAF)EM-Rhône: a project to produce e-methanol to help decarbonize maritime transport and serve as an intermediate for the chemical industry south of Lyon.
Elyse Energy has a two-fold goal: to control costs and minimize environmental impacts
Elyse Energy faces numerous challenges in the design and construction of these two e-molecule production plants:
In order to comply with regulatory requirements for low-carbon fuels (RFNBO: Renewable Fuels of Non-Biological Origin —Renewable Fuels of Non-Biological Origin), the molecules produced by Elyse Energy’s facilities must have a carbon footprint that is at least 70% lower than that of their fossil-based equivalents.
In Europe, the “ReFuel EU Aviation ” recently adopted by the European Parliament sends a strong signal by mandating SAF quotas at European airports, starting at at least 2% in 2025, 6% in 2030, and aiming for 70% in 2050. It is therefore particularly important for Elyse Energy to be among the first players in the sector to produce e-molecules to supply the market.
E-methanol and SAF production facilities are major industrial operations, whether in terms of their connection to the power grid, hydrogen production, or chemical synthesis processes.
Managing their environmental impact (such as water and heat recovery) is a key factor in the success of these projects.
Eras, a specialist in sustainable engineering
ERAS is a sustainable, multi-disciplinary engineering firm and a subsidiary of Equans France, and as such, supported Elyse Energy as a project management consultant for the launch of the two projects between late 2022 and 2023, ensuring a well-managed design process for both plants: industrial strategy, feasibility studies, cost and risk assessments, assistance with permitting processes, and more…
In 2024, ERAS continued to support Elyse Energy through the subsequent stages of its projects’ development by conducting pre-FEED design studies.
