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-metre facility is being constructed 30 metre below ground and will begin storing green hydrogen next year.

Given the goings-on in the world this last quarter, Mike Jefferies, Investment Manager at Octopus Investments Australia, takes a look at the current macroeconomic environment, how this is tied to energy markets, the impacts Russia’s invasion of Ukraine has had on that energy market, what this could mean for Australia and how renewables could help address these issues.

Elsewhere, the Danish government announced a plan to deploy up to 6 GW of electrolyser capacity by 2030 and Germany and Norway agreed to conduct a feasibility study on large-scale hydrogen transport, including via pipeline.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh (AU$0.18/KWh)

German luxury carmaker Mercedes-Benz has made public its plans partner with Primobius, a 50:50 joint venture between West Australian company Neometals and Germany’s SMS Group. Mercedes has said its intention is to build a 2,500 tonne per year lithium-ion battery recycling plant in southern Germany with Primobius as its technology partner.

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyser based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyser achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.

The Korean manufacturer and the German research centre were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.

Fortescue Future Industries and Airbus have formed a partnership, saying they will work together to realise a green hydrogen-based aircraft by 2035.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.
