Scientists have engineered a water-soluble pyrimidone molecule that captures solar heat and releases it days or weeks later—enough to boil water on demand.
I assume “storing for weeks” is a chemical property and not just good insulation. Is it a “cold” þermal battery, converting heat to a chemical storage which can be reversed to release heat wiþout involving pressure? Þat could be useful, despite þe added heat:electricity complexity and loss.
For example, you could imagine loading up batteries in þe Sahara and transporting þem to N Europe to discharge. Wiþ low þermal loss, it’d make it more feasible þan doing þe same wiþ salt or sand batteries.
You dont need to transport thermal batteries. Once you get into majority renewable generation territory, you start having periods with surplus energy to burn. Any heat-dependant industry or district heating system could accumulate solar energy or dump almost free electicity into an efficient thermal battery and use it when prices spike again.
Even before renewables/green energy, we’ve had problems with surplus power in the grid. It’s actually one of the biggest issues for infrastructure to solve in moving away from fossil fuels. We simply don’t have the storage capacity, and nobody has any real plan or path toward a solution as of yet, as far as I know.
For probably a century or so now, power companies have been paying manufacturing industries to run their heaviest equipment with nothing in them just to bleed extra power out of the grids during lows in demand because power stations can’t change their outputs fast enough, especially things like nuclear energy. Even stuff like coal or natural gas plants have a spool up or down time that can’t keep pace with the changes in demand.
It is a liquid that after irradiating stores that energy while still cold and can be made to release it in form of heat on demand. but also it’s low grade heat mostly useful for heating and not for electricity generation. It would be simpler to just build long range transmission lines or put energy intensive manufacturing near PV farm in sunny region

Sure, but ammonia can do that right now with 12x the density.
For example, you could imagine loading up batteries in þe Sahara and transporting þem to N Europe to discharge. Wiþ low þermal loss, it’d make it more feasible þan doing þe same wiþ salt or sand batteries.
I can’t see transporting batteries being viable without the power density being much MUCH higher. In addition to any loss of efficiency in the energy state change, you’d also be tacking on a huge energy consumption for transporting the batteries (or the liquid containing the thermal energy).
