RenU Fuel Solutions, a Spanish startup, aims to reprocess spent nuclear fuel to generate hydrogen through a process called radiólisis, utilizing the radiation emitted by the fuel. The company won €12,500 in awards at the EIT Jumpstarters competition in November.

Their approach requires no external electricity and could lead to hydrogen production costs below one euro per kilogram. They plan to build a pilot reactor by 2030, with market entry targeted by 2035, focusing initially on the French market and potential collaborations with existing nuclear technology firms.
