Hydrogen

Australia’s biggest energy retailer Origin Energy will team with Japan’s largest oil refiner Eneos to explore the potential of establishing a commercial-scale green hydrogen supply chain between Australia and Japan.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.

Two hydrogen platforms have launched in Australia to connect hydrogen producers with consumers, ultimately trying to catalyse projects and the industry more broadly. The first, NERA’s HyCapability, maps hydrogen capability across Australia, while the other focuses on New South Wales and the developments of its hydrogen hubs.

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.

The Australian government’s green bank has reaffirmed its intent to evolve beyond investing in solar and wind, expanding its focus to include green hydrogen, energy storage and transmission projects after finalising a string of investment firsts in the past 12 months.

In a campaign style speech, Andrew ‘Twiggy’ Forrest, founder of Fortescue Metals and one of Australia’s richest men, outlined his ambition of producing mammoth quantities of green hydrogen, a task he sees as imperative to stop the “planet cooking” while also cornering a market he believes will soon be worth trillions.

A new study from Stanford University and Cornell University shows that blue hydrogen can produce more greenhouse emissions than heat produced by coal and gas. The modelling classifies blue hydrogen emissions as carbon dioxide and unburned fugitive methane, as well as lifecycle emissions linked to the mining, transport, storage, and use of methane.

Australia’s proposed 26 GW Asian Renewable Energy Hub has encountered what appears to be a governmental double standard, as the country’s environment minister has rejected an expanded proposal. Thankfully, the project’s proponents have not become discouraged in the face of this double standard; in fact, they’re doubling down.

A bp Australia study partially supported by the Australian Renewable Energy Agency has confirmed the technical feasibility of large-scale renewable hydrogen and ammonia production for export in Australia, particularly in Western Australia’s Mid-West. However, the development of such an industry, says bp, requires strong government policy support, including a carbon price or emissions cap.

Researchers at the Indian Institute of Technology Bombay (IIT Bombay) have devised a method that increases hydrogen production up to three times while significantly lowering the energy required for water electrolysis.
