Solar-powered hydrogen refuelling station for unmanned aerial vehicles: Design and initial AC test results

Once the detailed design was completed, all components were installed and assembled, including a bespoke control system for self-governing off-grid operation. Grid-connected tests were then carried out to assess the components integration and acceptance prior to any unsupervised off-grid operation. It is expected that the system will provide enough field data to act as a test-bed towards a fully autonomous refuelling solution for UAVs.
