A new EWI Cologne study for TU Darmstadt and the DESERTEC Foundation models iron powder as a seasonal energy store and finds savings of up to 18 billion euros a year in a European system. The numbers are scenarios, and the technology is still at demonstration scale.
An Australian spin-out has won A$15m of public money to scale a ceramic tube electrolyser that runs on industrial steam. The efficiency gain is real and measured, but the demonstration is still only a few hundred kilowatts.
A 5MW system mixing alkaline and PEM electrolysers has won Chinese state recognition after field trials in Ningxia. The engineering targets fluctuating renewables, but the efficiency and cost data remain the developers’ own.
