Algae photovoltaics for hydrogen production
South Korea researchers have developed a cell by merging green algae with carbon nanofibers, in order to generate 9.5 W per cell and achieve a peak efficiency of 0.9%. They claim this is enough to power a micro-generation system for hydrogen production.
Solar-plus-storage outperforms diesel in military survivability analysis
The NREL evaluation of solar plus Antora Energy storage system meets the U.S. Military’s exacting standards, revealing that these systems significantly outperform emergency diesel generators in survivability probabilities.
Quasi-solid-state magnesium-ion battery achieves energy density of 264 Wh/kg
Researchers at the University of Hong Kong (HKU) have developed a quasi-solid-state magnesium-ion battery with a voltage plateau at 2.4 V and an energy density of 264 Wh/kg. It surpasses the performance of current magnesium-ion batteries and almost matches the performance of lithium-ion batteries.

HPS Home Power Solutions unveils hydrogen residential storage system
Germany’s HPS Home Power Solutions says its new 15 kW system uses surplus power from PV installations to produce hydrogen via electrolysis.
Install grid-connected solar, rinse, repeat
Will a redeployable solar and energy storage solution be the answer to unreliable grid electricity across much of Africa, as its developer proposes? Or will it merely be a temporary solution that will see cash-strapped utilities kick the can of universal energy access further down the road?
Ensuring a just and inclusive energy transition for the Global South
Amid calls for an immediate transition to renewable energy, it’s important to ensure that aspects such as domestic resource utilization, the cost of transition, and the impact on the population are not overlooked.
Investigators still uncertain about cause of 30 kWh battery explosion in Germany
A lithium iron phosphate (LFP) battery system recently exploded in a home in central Germany, preventing police and insurance investigators from entering due to the high risk of collapse. The explosion may have been preceded by off-gassing, but it remains unclear whether an external ignition source was the cause. Some scientists say thermal runaway may have triggered the blast.
