TECHNOLOGY OVERVIEW

In recent years, carbon dioxide (CO2) levels in the atmosphere have reached unacceptably high levels. The CO2 in the air can be captured but a method of effectively utilising or sequestrating it remains to be found. Therefore, there is a need for a new technology that can cost effectively, and energy efficiently utilise or sequestrate CO2.

This technology offer uses a natural, low-temperature, liquid-phase processes to electrochemically convert captured CO2 into syngas, a mixture of hydrogen (H2) and carbon monoxide (CO). This is highly desired as syngas is the precursor of many useful materials such as plastics, ammonia, methane and methanol and is typically made from fossil fuel.  Any emitters of CO2 could integrate this technology into their plants to both reduce their carbon emissions and increase overall system efficiency.  The projected costs show that the syngas will be able to compete with fossil sources based on price, in many cases, without the need for a carbon subsidy or relying on any value from the oxygen (O2) produced as a co-product.

The technology owner is looking for partners in various CO2 emitting industries for further co-development and test bedding of the solution. The technology owner is also keen to license this technology as well.

TECHNOLOGY FEATURES & SPECIFICATIONS

This technology is a low temperature liquid-phase electro-conversion of CO2 to syngas. The technical features & specifications are as follows:

  • Electrochemical conversion of CO2
  • Produces syngas (H2 & CO) and O2 at separate electrodes
  • Proprietary catalysts, devices, processes and systems
  • Carbonised electrolyte (Method to convert gaseous CO2 into electrolyte)
  • Regenerative electrolyte (Decarbonised electrolyte recirculated as input in carbon capture subsystem)
  • Easy and cheap transportation of CO2 (In carbonised electrolyte form)
  • Competitive price of syngas (Margin dependent on price of electricity)
  • Remote coupling of carbon sources with syngas users

POTENTIAL APPLICATIONS

This technology is applicable for those industries which emits CO2 or has syngas precursor requirement. The potential applications are:

  • Recycling carbon emissions for high CO2 emitting industries (e.g. power plants, steam reformers, oil refineries, steel mills, aluminium, cement plants and ships)
  • Cheap and green syngas precursor (for chemicals, fuels, hydrogen, plastic use etc.)

Unique Value Proposition

  • Eliminate carbon emissions
  • Cost effective electro-conversion process (even without carbon subsidies)
  • Production of useful products (syngas and O2)
  • Circular economy (regenerative carbonised electrolyte)
  • Simple integration into existing plants and improve overall system efficiency
