Technology Collaboration Programme

Advancing the research, development and commercialisation of energy technologies

The IEA Technology Collaboration Programme supports the work of 38 independent, international groups of experts that enable governments and industries from around the world to lead programmes and projects on a wide range of energy technologies and related issues.

More about collaboration on

Clean and Efficient Combustion (Combustion)

The Combustion TCP provides a forum for interdisciplinary exchange and enables international collaborative research to advance the understanding of combustion processes to: accelerate the development of combustion technologies that demonstrate reduced fuel consumption and have lower pollutant emissions in transportation, power generation, industry and buildings, and; generate, compile and disseminate independent information, expertise and knowledge related to combustion for the research community, industry, policy makers and society.

Main areas of work

Key activities and accomplishments (2017-18)

  • Fundamental combustion science advancements documented in peer-reviewed journals;
  • Advanced computer-aided design capabilities to enable clean combustor design;
  • Demonstration of low temperature combustion showing potential for 20-25% higher fuel efficiency with lower CO2 and pollutant emissions than current fleet averages;
  • Developed pathways to substantial CO2 savings and ultra-low pollutant emissions from high fuel efficiency, lean-burn natural gas engines;
  • Established gas turbine tolerance to H2 addition in the fuel stream, promoting the transition to an H2 energy economy.

Priorities and projects (2019-20)

  • Synthesising the science base needed to optimise combustion technologies for use of renewable fuels and minimal environmental impacts;
  • Promoting sustainable, economically accessible energy solutions;
  • NEW – systems analysis: placing the impact of advanced combustion and renewable fuels in the broader context of other low-carbon solutions;
  • NEW – exhaust aftertreatment: examining how closer collaboration between aftertreatment and combustion engineers can alleviate design constraints on both sides.

Multilateral collaborations

  • Current collaboration on heavy duty vehicle performance evaluation with the TCP on Advanced Motor Fuels (AMF TCP)
  • Interest in further collaboration with the AMF TCP and Bioenergy TCP, as well as in transportation energy systems analysis with the Energy Technology Systems Analysis Programme (ETSAP TCP) and Hybrid and Electric Vehicles TCPs


Why should your organisation become a member of Combustion?

Clean, efficient, cost-effective combustion technologies are key elements of a reliable and sustainable, low-carbon energy system.  The Combustion TCP provides a forum for exchange and collaborative research to advance the understanding of combustion processes, and to generate independent information, expertise and knowledge to the wider research community, industry, policy makers, and society.
