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?

A new experimental facility at the University of Wisconsin-Madison, the Dual-Advanced Ion Simultaneous Implantation Experiment (DAISIE), has been designed and constructed to examine tungsten surface damage phenomena. These include microstructure formation and erosion due to helium bombardment as well as the retention of hydrogen gas while under the simultaneous bombardment of helium and deuterium ion beams, as would occur in ITER or other deuterium-burning fusion devices. DAISIE features two ion guns angled at 55° to the sample normal. These guns are independent with respect to beam current, allowing for a high degree of control over the separate D and He beams fluxes and fluences and the composition ratio of these ions impinging upon the tungsten sample surface. Preliminary results are available for helium-only implantations at energies of 30 keV to average fluences of 3 × 1018 He/cm2 in tungsten samples at temperatures of 900°C. As in prior experiments, surface damage appears to be highly-dependent on the crystallography of the individual grains. although a distinct set of helium-induced microstructures from past experiments is observed. Erosion yield is consistent with prior, similar helium irradiation experiments at the University of Wisconsin, but exceeds that predicted by physical sputtering yields and other past sputtering experiments.
