Completed Projects
The Efficiency for Access Research and Development Fund has supported 38 organisations with over £5 million in funding and facilitated a further £1.5m to 12 electric cooking projects with funding from UK aid. Here are the completed projects.
The Efficiency for Access Research and Development Fund was launched in November 2018 and aims to accelerate innovation in off-grid and weak grid appliance technologies.
Efficiency for Access is investing funding into research and development (R&D) projects with the aim to accelerate the availability, affordability, efficiency and performance of a range of low energy inclusive appliances that are particularly suited to developing country contexts and promote social inclusion.
Launched in 2018, there have been three calls for funding: the Open Call, the Cooling Call and the Enabling Technologies Call. Some of our projects have now been successfully completed, with the impacts of the projects measured.
First Open Call 2018
