Technical feasibility of a proton battery with an activated carbon electrode
Appears to use an activated carbon electrode as a hydrogen store, paired with a reversible fuel cell, to make a complete proton battery

Chinese researchers achieve breakthrough in nuclear energy -
So the main trick behind ADANES is using a tungsten grain based solid neutron spallation target that pumps like a liquid, giving fluid properties but solid heat capabilities (to better survive beam trip transients), and the potential to be a windowless particle beam target (improving lifetime).

Interesting filtering trick, to sieve out cracked hydrogen ions. May be useful for fuelcell fuel production and avoiding fuel poisoning.

GTAT (of Apple sapphire fame) acquired these guys and improved on their high current/energy particle accelerator tech. Allegedly 10x better than equivalent accelerators and very compact at version 3. Should be useful as an injector stage for a larger particle accelerator.

Towards a ‘proton flow battery’: Investigation of a reversible PEM fuel cell with integrated metal-hydride hydrogen storage
Now that's smart, integrating a metal hydride hydrogen sponge as an electrode in a PEM fuel cell to skip a step. Though it turns the setup essentially into a closed cycle battery, fixed to the capacity of the metal hydride electrode's internal storage capacity, hence the "battery" nomenclature.

TRU burner ADSR molten salt reactor design, using triple strong focus cyclotrons and a sodium chloride salt. Kinda interesting in comparison to various lead cooled FFAG type ADSR's.

Apparently these guys have a proton accelerator that operates at both high voltage and current, approximately 10x better than current proton accelerators (for what I assume are semiconductor applications...). Useful for making thin wafers for semiconductors, but the proton accelerator part is more interesting.

Very Big Accelerators for Energy Production
I wonder if the upfront expense of an accelerator complex can be justified by designing in multiple beam splitters feeding multiple small subcritical thorium breeder reactors (LFTR?), to allow a slow ramp up of plant capacity? Taking the next big leap, put the accelerator complex onboard a tanker deck, and gradually fill the holds with small nuclear reactors, and drive the energy tanker to cities needing power.

Neat trick of using a two layer optimized blanket to reduce the amount of accelerator input power required for a accelerator driven subcritical reactor, though how practical it would be is up for debate. Admittedly, this is more oriented for transmutation/actinides burning. For power, you might end up with an inner blanket, lead-bismuth coolant, and a separation/heat exchanger vessel for the main liquid fuel (like a LFTR), and finally an outer heat exchanger from lead to steam (though I would rather use supercritical CO2). There may be an advantage to going to a liquid blanket as well.
