green hydrogen

A 600 kW, container-based solar array will be used to electrolyze green hydrogen at a mine in Limpopo, South Africa after Engie signed a two-year lease for the mobile system, at Anglo American’s Mogalakwena site.

Moreover, two big Russian corporations have unveiled plans to produce hydrogen and Portuguese utility EDP said it wants to set up a a pilot project for a green hydrogen plant in Brazil.

Australian hydrogen vehicle manufacturer H2X will unveil the Warrego, a fuel cell electric hybrid pickup truck, in November.

H2 Energy Europe is building a power-to-gas project in Denmark and Everfuel wants to put hydrogen refueling stations in Sweden. Chinese energy giant Sinopec said it wants to invest massively in hydrogen and the Australian Energy Market Operator (AEMO) has said hydrogen will be the main driver for “very quick” growth in electricity demand.

Conceived by Swiss researchers, the battery shows good stability over 50 cycles, with an average energy efficiency of 68% and a water-splitting voltage efficiency of 64.1%. According to its creators, the device produces pure hydrogen that only needs to be dried and compressed for optimal storage.

Origin Energy, Australia’s biggest energy retailer, has agreed to team with Japan’s largest oil refiner, Eneos, to explore the potential for a commercial-scale green hydrogen supply chain between their respective home markets.

Furthermore, the Indian government is proposing to mandate using green hydrogen in fertilizer and refining and Japanese automotive manufacturer Toyota wants to assemble integrated dual fuel cell (FC) modules in the United States.

A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolyzers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.

Spanish energy giants Repsol and Enagás are planning to build an electrolyzer based on photoelectrocatalysis at an industrial complex owned by the oil company in Puertollano in 2024. The device receives direct solar radiation and with a photoactive material it generates the electrical charges that cause the separation of the water molecule into hydrogen and oxygen.

Australia has the sun, the wind and the space to become one of the world’s green hydrogen export superpowers in coming decades. However, the Sunburnt Country does have a dearth of one ingredient in the green hydrogen equation – freshwater. Thankfully, researchers from Monash University and a group of national water utilities are joining forces to find a way to use wastewater for the process of electrolysis.
