Liquid hydrogen test flight could enable long-distance flights
H2FLY claims that a recent three-hour test flight, entirely powered by liquid hydrogen, could lead to sustainable long-range flights fuelled by liquefied, cryogenic hydrogen. Solaris, meanwhile, has started selling hydrogen buses in Italy.
‘No transition policy is going to be realised with current strategies’: shifting focus to existing grid’s untapped 10 GW
New digital modelling technology has made visible 10 GW of untapped capacity in Australia’s existing electricity networks. “That 10 GW number is probably achievable without any meaningful incremental cost investment,” Neara cofounder Jack Curtis tells pv magazine Australia. “This is something that’s really only come into awareness of policy makers, and even the private sector, in past six months.”
How long do residential solar panels last?
Multiple factors affect the productive lifespan of a residential solar panel. In the first part of this series, we look at the solar panels themselves.

Anode-less redox flow batteries capable of fast cycling
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
The case for hard carbon-based sodium-ion batteries
Researchers in China have summarised the technical issues hindering the development of hard carbon, which is regarded as the most promising anode for high-performance, commercial sodium-ion batteries.
