TOTALENERGIES ONETECH

Their core work

TotalEnergies OneTech is the technology and R&D arm of the TotalEnergies group, focused on developing and deploying carbon capture, utilization, and storage (CCUS) solutions for heavy industry. They contribute industrial expertise in CO2 capture processes, combustion emissions reduction, and integration of low-carbon technologies into petroleum refining and energy-intensive sectors. Their H2020 involvement spans from testing chemical looping and DMX-based capture at industrial sites to exploring quantum computing applications and renewable fuel integration for transport.

What they specialise in

How they've shifted over time

Early H2020 work (2017–2019) centered on established CCS technologies — chemical looping combustion for petroleum refineries, heavy fuel emissions, and the DMX CO2 capture process demonstrated at a blast furnace site in Dunkirk. By 2020–2021, the focus broadened significantly toward next-generation carbon dioxide removal across diverse industrial sectors (cement, pulp and paper, waste-to-energy), enzymatic solvents, and concrete recarbonation. This shift signals a move from fossil-fuel-specific emission fixes toward wider industrial CCUS deployment and circular carbon approaches.

TotalEnergies OneTech is expanding from oil-and-gas-centric carbon capture toward becoming a broad CCUS technology provider for hard-to-abate industries like cement, waste-to-energy, and biorefining.

How they like to work

TotalEnergies OneTech participates exclusively as a consortium partner — never as coordinator — which is typical for large energy corporations contributing domain expertise and industrial test sites without taking on project management overhead. With 94 unique partners across 19 countries in just 5 projects, they operate in large, multinational consortia. This makes them an accessible partner: they bring major-industry credibility and real-world deployment context without competing for project leadership.

Despite only 5 projects, TotalEnergies OneTech has built a broad network of 94 partners across 19 countries, reflecting their involvement in large-scale demonstration consortia. Their geographic reach extends beyond Europe through the CHEERS project's China collaboration.

What sets them apart

As a technology division of a major energy company, TotalEnergies OneTech offers something few academic or SME partners can: access to real industrial sites (refineries, chemical plants) where CCUS technologies must actually work at scale. Their portfolio demonstrates willingness to test emerging capture methods — from chemical looping to enzymatic solvents — under actual operating conditions. For consortium builders, they bring both the technical depth and the industrial validation environment that turns lab research into deployable solutions.

Highlights from their portfolio

• CHEERS
  Largest funded project (EUR 685K) addressing China-Europe cooperation on industrial CO2 reduction — rare cross-continental scope combining petroleum refinery decarbonization with chemical looping technology.
• 3D
  Landmark DMX CO2 capture demonstration at ArcelorMittal's Dunkirk blast furnace site with full CCS chain including North Sea storage — one of Europe's flagship industrial CCS pilots.
• ACCSESS
  Most recent and forward-looking project, targeting flexible CCUS deployment across five different industrial sectors including concrete recarbonation and enzymatic solvents.
