Today, up to 95% of hydrogen (H2) produced is termed grey H2 as it is formed via steam methane reforming (SMR) using fossil fuels such as natural gas. This hydrogen is used in producing everything from fuels to plastics and is aptly named grey H2 as the carbon dioxide (CO2) from this reaction is expensive to capture and is often released or sent to the stack to be burnt off. With the global net-zero CO2 emissions target looming, there is an urgent need for technologies that can improve the efficiency of processes using grey H2 and economically capture the released CO2 making grey H2 into blue H2.

This technology offer is a hydrogen separation membrane that reduces the cost of hydrogen purification and carbon capture. It is a temperature and corrosion-resistant membrane that is able to selectively filter out H2. By splitting syngas into H2 and CO2-rich streams, it simultaneously purifies hydrogen and pre-concentrates the CO2 for transport and sequestration. Furthermore, there is an additional benefit that waste H2 can be inexpensively recovered to improve the overall process efficiency. Hydrogen plants incorporating this technology now produce blue H2 and can generate additional income through higher efficiencies, hydrotreater margins, and carbon credits.

The technology owner is seeking partners and collaborators, especially those in the oil and gas refineries or other H2 intensive industries, for pilot trials of their technology.


This technology offer is a proprietary polymer membrane that enables carbon capture via hydrogen separation. The features and specifications of the technology are as follows:

  • Hollow fibre membranes (polymer-based)
  • H2 selective (up to 99.95% pure)
  • Temperature resistant (up to 150oC)
  • Corrosion and contaminants resistant (e.g. H2S, C4-C6 hydrocarbons)
  • Able to process 5-500m3/hr of gas (per module, based on 36km fiber in a 10" by 1m configuration)
  • Widely applicable to H2 purification and readily scalable modular design
  • Can generate carbon credits through supporting COcapture  


This technology can be applied to almost all industrial processes that produce or use H2. The potential applications are (not limited to):

  • H2 recovery (hydrotreater and refinery off-gas, green hydrogen storage etc.)
  • Sustainable hydrogen generation (bio-conversion, pyrolysis, and biomass gasification)
  • Enabling carbon capture via H2 separation (SMR etc.)
  • H2 separation process (petrochemical production, plastics manufacturing, hydrogenation of fats, solid oxide hydrogen engines etc.)

Market Trends & Opportunities

Global efforts to decarbonize are expected to cause the demand for blue and green H2 to grow enormously over the next couple of decades, taking this $100B market to more than $500B by 2050. However, today, as much as 99% of the H2 produced is from syngas or SMR. These grey H2 processes are of enormous scale, integrated within large refineries and chemical plants, and are not easily replaced by emerging green H2 production methods. Coupled with the difficulties associated with recovering valuable H2 from off gases that are currently flared, there is a massive opportunity for technologies that can operate in these conditions to make grey H2 blue.

Unique Value Proposition

  • Simple and cheap separation method for H2
  • Carbon credits from carbon capture
  • Process and cost recovery from recycling of H2

This technology offers a more energy-efficient method of capturing hydrogen from industrial gas streams, replacing costly Pressure Swing Adsorption (PSA) units and pre-treatment processes required by other membranes in these applications.
