• Low energy consumption process
  • Non-proprietary solvent
  • No thermal and oxidative degradation

  • Simple chemistry
  • Tolerant to oxygen
  • High capture rate

  • Power generation (e.g., waste-to-energy plants, biomass power plants, etc.)
  • Industrial (e.g., cement plants, etc.)
  • Oil and gas (e.g., SMRs, utility boilers, etc.)




In December 2020, Baker Hughes signed an exclusive global licensing agreement with research group SRI International for its mixed-salt process (MSP) for carbon capture. The technology received support from the US Department of Energy’s Office of Fossil Energy and National Energy Technology Laboratory (NETL).

MSP is a post-combustion, carbon-capture process that uses a novel solvent formulation based on readily available potassium and ammonia. It has achieved a technology readiness level (TRL) of 4 according to the H2020 definition, and an MSP pilot project for demonstrating TRL 6 is under execution. Its solvent is not influenced by trace components (e.g., NOx, O2) or thermal and oxidative degradation. MSP is tolerant to oxygen, high temperatures, and flue gas impurities.
