Nuclear fusion is going from strength to strength, with several technological breakthroughs in recent years, including the ability to build high-temperature superconducting (HTS) magnets that can generate high magnetic fields with almost no energy loss. This is important not only because it increases the obvious net energy production, but also because it may be possible to build more compact magnetic fusion devices such as tokamaks and stellarators. The dimensions of these machines are much smaller than those of ITER, and this has attracted the attention of industry in a variety of ways, from larger and more experienced companies focused on manufacturing, to a proliferation of start-ups focused on novel reactor designs and software modelling.
Part of the industry is developing artificial intelligence (AI) solutions to fusion problems. Two of these companies, digilab and Next Step Fusion, have recently visited the Fusion Group at the Barcelona Supercomputing Center headquarters.
