Sulphur-based redox flow battery with 15 consecutive hours of runtime
Researchers from Hong Kong have applied a novel charge-reinforced, ion-selective (CRIS) membrane to a polysulfide-iodide redox flow battery they had built in 2016. The redox flow battery showed a capacity decay rate of just 0.005% per day for 1,200 cycles, and a lifetime with over 2,000 hours’ cycling, which the academics said corresponds to approximately three months.

Floating PV and flow batteries to power highways’ junction in the Netherlands
A floating PV array coupled to flow batteries is planned to power the operations of a new road under construction to connect two highways in the Netherlands. The project is aimed, in particular, at powering ventilation, lighting, and other installations of a tunnel.
India’s NTPC launches tender for 1 GWh of grid scale storage
State-run power producer NTPC has more than 65 GW of installed capacity, including gas, coal, hydro, and renewables-based power stations.
Using the oceans’ depths to store renewables, compress hydrogen
Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.
East African renewables developers and investors need matchmaking
Lack of grid capacity and renewable energy institutions are a common lament in sub-Saharan Africa but there is no lack of cash to invest, nor eligible projects in East Africa, as a recent event heard; the problem lies in marrying the two.
World Bank supports Burkina Faso’s rural solar electrification with $168m
