Catalytic combo converts CO2 to solid carbon nanofibers while offsetting emissions 2024 Jan 11 Phys.org techxplore.com/news/2024-01-catalytic-combo-solid-carbon-nanofibers.htmlThe carbon nanofibers are a useful concrete additive, storing the carbon for a long time. The process also produces H2 for the hydrogen economy. Process heat required is but 400 ºC, easily obtainable.

Gravity Energy Storage Systems: Transforming Defunct Mines Into Efficient Energy Producers John Nieman 2024 Jan 07 EEPower eepower.com/news/gravity-energy-storage-systems-transforming-defunct-mines-into-efficient-energy-producers/Not ‘producers’ but rather stores, please. It looks like ABB is going to do the engineering involved in these mine shaft lifts. Nothing is said about the site remediation which is at least desirable if not required for disused underground mines. As for efficiency, I opine around 70% of the energy used to hoist the weights is recoverable in the descent.
