SILSTORE
Very high temperature (up to 1400C) molten silicon thermal energy storage. The kicker seems to be using concentrated solar power to melt, and a thermophotovoltaic system to recover power rather than a brayton cycle turbine using an intermediary fluid.

Fuel Cells Finally Find a Killer App: Carbon Capture - IEEE Spectrum
hrm, how hot is the CO2 exhaust? Can you get it to supercritical pressure/temperatures? There's that NETpower allam cycle demo that uses an oxyfuel gas turbine with similar inputs/outputs. The MCFC is more tolerant of inputs, but the allam cycle turbine might have better power output? What is you use a MCFC as a topping cycle replacement of an allam cycle combustor?

Halotechnics - Power through storage
Current solar salts are near 585C max. New eutectic salt can reach 700C with similar materials compatibility. They also have a new glass derivative with a depressed melt point of 400C (normal window glass is 600C) that can run up to 1200C. The glass based thermal storage seems to be intended for hot air aeroderivative turbines/combined cycle setups rather than just steam turbines. Claim low cost components of the eutectic salt, discovered using advanced automated chemical mixture analysis.

Nuclear combustion combined cycle (NCCC) setup is interesting. Use a high temperature reactor with molten salt coolant loop to provide more heat than methane autoignition temperature (630C), slip a molten salt heat exchanger after the compressor but before the combustor of an open air cycle gas turbine combined cycle rig. Run on exclusively reactor heat normally, but pump in methane for peaking. May need a HRSG bypass when not peaking unless you treat the HRSG heat exchanger as a feedwater heater to the primary steam plant of the reactor. Step this up a bit with integrated ASU for oxyfuel ops, a post HRSG exhaust gas heat exchanger to preheat post compressor oxygen before hitting the molten salt exchanger, and flush stored ASU LN2 through an air turbine and pipe the cold exhaust through the steam condenser stack. Similar to the old ANP indirect cycle airplane engine, which is itself an open cycle brayton turbine running on reactor heat.

Enel Inaugerates Molten Salt Thermal Energy Storage System for Archimede Solar Thermal Power Plant « Solar Thermal Magazine
Apparently this is a parabolic trough type solar thermal plant with molten salt in the collector tubes, which is a first apparently. I wonder how they keep the salt from freezing in the tubes at night? Do they drain it, or accept the losses associated with keeping it molten directly in the tube at night? They mention a combined cycle plant, so maybe they vampire heat from the plant to keep the salt hot?

Solar Thermal Electrochemical Photo (STEP) Carbon Capture could Reduce Atmospheric CO2 to Pre-industrial Levels in Ten Years
Using an externally electrically driven molten lithium carbonate cell to crack CO2 down to C or CO, CO being fed into synthetic fuel processes, C for solid state long term sequestration/storage or as nanotube feedstock. Uses Solar CPV with thermal recovery to heat the cells and drive them electrically. Absolutely no mention of how the CO2 would be captured for input into the electrolysis cell (basically the same as a MSFC fuelcell, only without the hydrogen fuel) though.
