Helion is planning to use a different fusion reaction, one where the bulk of the energy will be coming out as charged particles, not neutrons. However, D+T fusion is the only type of fusion that we have been able to sustain for any significant amount of time with reasonable energy inputs. What Helion is planning to do is completely unexplored and requires some major scientific advances.
