To reach that goal, five Renewable Energy Technologies, reaching TRL 7-8 will be improved, adapted to the local context and demonstrated in two sites in Uganda and Rwanda, reaching around 1300 refugees and persons in the local host populations. The technologies developed in SUNNY will be upgraded following circular economy and local value chain approaches in order to create economic activity locally as well as ensure relevance of the solutions and long-term sustainability. To ensure uptake, a strong focus will also be made on cost-effectiveness and adapted business models. Solar home systems will ensure the access to basic energy needs at a household level (PR1). Clean hydrogen (PR2) and biogas (PR3) cooking solutions will allow cooking to be decarbonised while improving health conditions. Refrigerated food storage (PR4) and smart solar irrigation, combined with biogas, will allow to improve food security in rural African areas and address the WEF nexus. Holistic models (PR5) and assessment methods (PR8) will allow to identify and validate the benefits and sustainability of the technologies, while social innovation through among others capacity building will support the long-term socio-economic impact (PR6) and ensure local uptake as well as a strong replicability potential. Indeed, SUNNY ambitions to widely impact humanitarian energy practices through a replication plan comprising the involvement of 15 replication cases with new interoperability of technologies, training activities towards African and EU-wide energy-access and development agencies and camps managers, and policy recommendations (PR8).
