The Energy Catalyst programme accelerates the innovation needed to end energy poverty. Through financial and advisory support, and by building strategic partnerships and uncovering new insights, Energy Catalyst supports the development of technologies and business models that can improve lives in Africa and Asia. Energy Catalyst is an Innovate UK programme with co-funding from the Foreign, Commonwealth and Development Office, Global Challenges Research Fund, the Department of Business, Energy and Industrial Strategy and the Engineering and Physical Sciences Research Council. Over the two years 2019, when GCRF began funding Energy Catalyst, and 2020, £8.4 million GCRF funding was dispersed through the Energy Catalyst Programme. The UK is an active member of the International Energy Agency and has worked to ensure that the Agency has a strong focus on helping its members and the wider energy sector accelerate the clean energy transition drawing on its world-leading analysis and convening power. In 2021 the UK commissioned the production of the IEA's 2050 Net-Zero Road Map for the energy sector. The report is the world's first comprehensive study of how to transition to a net zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth. Pollution Management and Environmental Health (PMEH) programme. However, as the programme moved into implementation, it was found that the target countries already had suitable equipment, and the programme was insufficiently flexible to allow for alternative activities (within the agree scope of the UK funding) to be supported. The UK's evidence collection at business case stage has since become more robust, with the UK collecting evidence of demand from a range of sources. Unused funds from the PMEH Programme were re-directed to other ICF Programmes.
