We aim to develop a “plug and play” power storage system with a 1 MW electrolyser integrated that stores the energy generated by existing idle renewable power plants (e.g., hydropower plants) during off peak hours through green hydrogen production and utilization of batteries as power support. The stored energy will be converted back to electricity through a fuel cell generator technology to supply local grids during hours of peak demand. We plan to perform a pilot project with Industrial Promotion Services (IPS) in Uganda. IPS is the owner of WENRECO, a utility company in the rural West Nile region of Uganda. The pilot project will consist in developing, testing and validating our plug and play system at the 3.5 MW Nyagak I hydropower plant that serves 21,000 local customers in the West Nile region, demonstrating the technical, operational, environmental and socio-economic viability of the system to effectively satisfy energy demand during peaks.
