The case for aqueous zinc-ion batteries

Scientists in Germany have identified the main challenges that are preventing aqueous zinc-ion batteries (ZIBs) from becoming a mainstream storage technology for power grid applications. According to their analysis, the two main hurdles that must be overcome in future research are the increase of the specific energy of the full Zn-ion cell and the prevention of the parasitic hydrogen evolution reaction occurring during the Zn electrodeposition step.

Romania invests in PV cell and panel supply chains

A lack of trained personnel, slow overhaul of PV rules, and a weak electricity grid could slow the emergence of solar as a solution to diminish Romanian dependence on Russian gas. The next two winters will be critical.

Invasion of Ukraine an inadvertent boost for green hydrogen

Rystad Energy has joined BloombergNEF with a significant forecast for gray and blue hydrogen off the back of Russia’s invasion of Ukraine. According to the analysts, the impact of the war has sent prices of fossil fuel-tied forms of hydrogen production surging, leaving the gradual but consistent downward price trend of green hydrogen now looking remarkably competitive.

Sweden’s first rock cavern for green hydrogen storage takes shape

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-meter facility is being constructed 30 meters below ground and will begin storing green hydrogen next year.

Monolithic fuel cell with power density of 5.6kW/L

An international research group has developed a solid oxide fuel cell that may be used in vehicles. The monolith device has an active cell area of around 18 cm2 and was built through common manufacturing processes. It was found to achieve a high power density of 5.6 kW/L, which the scientists said is comparable with that of the best performing fuel cells based on ceramic anodes.
