Western Australian gas utility ATCO Australia has achieved a network distribution blend of up to 10% renewable hydrogen, produced by a solar-powered electrolyzer, for 3,000 homes.

Researchers in Pakistan have tested several configurations of an offgrid PV-hydrogen system intended to power EV chargers. The system achieved the lowest levelized cost of electricity when it was combined with battery storage.

Investment confidence in Australia’s green hydrogen industry has received a $660 million boost following a joint declaration with Germany to negotiate supply chains that guarantee European buyers for Australian products.

Australia’s Clean Energy Finance Corporation has backed a hydrogen fuel cell developer $7 million to support an innovative form of technology using silicon-based bipolar plates.

A survey of 1,797 residents was used to determine the willingness to pay for low-carbon residential heating in the Netherlands. On average, respondents were willing to pay a premium of 33% for electricity-based heating. Policy recommendations were also provided as part of the study.

Researchers in Spain have made a comparative analysis of annual PV-powered hydrogen production for direct and indirect configurations and have found that indirect systems not only produce more hydrogen but also that they show higher resilience to module power losses.

The Israeli Ministry of Energy and Infrastructure has presented three scenarios for its 2050 green goals, changing in accordance with developments in solar, hydrogen, and nuclear power production. In the most solar-focused scenario, the country would have a PV capacity of 108 GW.

A German research team has compared the economic performance of an offgrid PV-electrolyser-fuel cell system with that of a standalone solar-plus-storage counterpart in a building in Niger. Its analysis showed that decentralized PV-driven hydrogen could achieve considerable lower levelized cost of energy and levelized cost of storage than the PV-battery system, with these values reaching €0.12 ($13.1)/kWh and €0.35/kWh, respectively.

Scientists in Australia have incorporated overload capacity and power-dependent efficiency of the electrolyser in a novel techno-economic model to calculate the levelized cost of hydrogen. The proposed methodology was applied to ascertain the impact of internalizing environmental costs on the cost-competitiveness of green hydrogen compared to grey hydrogen.

New research from the UK shows that Oman could utilize a floating PV farm at the Wadi Dayqah Dam for hydrogen generation. The scientist said the project is technical viabile, although only with advancements in hydrogen energy storage technology could make it economically feasible.
