On 12 November 2026, the kick-off meeting for the MARRS project is taking place in Arlington, Virginia, with representatives from the “Jožef Stefan” Institute attending alongside the University of Szczecin. The “Mechanisms for Increasing the Rate of Fusion Reactions in Solids” initiative MARRS is funded by the US Defence Advanced Research Projects Agency (DARPA) and aims to investigate mechanisms that increase the rate of nuclear fusion reactions, with potential applications for low-cost, clean and safe fusion reactors for a sustainable future. The MARRS project intends to investigate the latest breakthroughs in theoretical predictions and experimental evidence relating to nuclear fusion reactions in metallic lattices, also known as ‘Lattice Augmented Nuclear Reactions’, ‘Low Energy Nuclear Reactions’ or ‘Cold Fusion’. These results show that fusion rates increase significantly when deuterium atoms are embedded in a metallic lattice. The selection of these two European institutions is the result of the exceptional findings produced by the European Union’s ‘CleanHME’ project; these findings have demonstrated the existence of a previously unknown deuterium-deuterium fusion channel. This is an exceptional honour for the researchers and their work at the JSI.
