Proxima Fusion / RWE / Bavaria / Max Planck IPP

Proxima Fusion, RWE, the Free State of Bavaria and Max Planck IPP signed an MOU to build Europe's first commercial stellarator fusion plant. It starts with 'Alpha', a €2B (~$2.3B) demonstration stellarator in Garching aiming to be the first stellarator to reach net energy gain (Q>1) in the 2030s; a commercial 'Stellaris' plant would follow at RWE's decommissioning Gundremmingen nuclear site. IPP leads physics, Proxima engineering, RWE plant construction.
