Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Ion Cyclotron Wall Conditioning (ICWC) has been performed in KSTAR. Fuel retention and removal, impurity removal have been investigated in a dedicated session. By varying pressure (mixture rate) and duty cycle, parameter study has been done. An average hydrogen retention rate of ~2 × 1020 H/sec is measured. The ratio of Himplanted/Dpumped is found to be ~5-15 depending on the operation conditions. Other impurity removal rate is of the order of ~1016-1017 molecules/sec. It is shown that inter-shot ICWC is a powerful tool for superconducting tokamaks like KSTAR and ITER.
