Hydrogen

Burning biomass – essentially, wood – is defined by the Australian government and the United Nations as a renewable energy source. As Australia’s hydrogen pipeline balloons, projects proposing to produce the ‘future fuel’ by burning waste wood have begun to appear. It’s a model that has immediate benefits, complicated drawbacks and significant carbon emissions along the way.

More than half of regional Queenslanders believe clean energy industries will be major employers by 2030, according to a new survey, while just shy of half support transitioning to a renewables-dominated grid in the next 15 years or sooner. The survey focussed only on regional Queensland, excluding greater Brisbane area and Gold Coast, an area renowned for conservatism.

The number of residential home batteries in Queensland has doubled while electricity bill cost concern has almost halved, found the “biggest survey of its kind” conducted in the state. The survey’s findings, which set to be released in full later this week, were summarised this morning by Queensland Minister for Energy, Renewables and Hydrogen, Mick de Brenni, at a virtual event.

What’s happening around the states? Western Australia to welcome big battery; South Australia developer plans major expansion; NSW solar farm rejected; and feasibility study supports Queensland green hydrogen project.

According to a new study from the Massachusetts Institute of Technology, hydrogen-fired gas plants will compete with lithium-ion storage for seasonal storage and their competitiveness will strictly depend on the heat rate of the gas power plants they may replace.

The generator can be combined with batteries, solar panels, or small wind turbines. It is based on a proton exchange membrane fuel cell technology and is claimed to have a minimum lifetime of 5,000 working hours.

Hydrogen vehicle maker, Hyzon Motors, has signed an agreement to deliver five fuel cell-powered heavy-duty trucks to Ark Energy Corporation, the Australian subsidiary of the world’s largest zinc, lead, and silver producer, Korea Zinc Ltd.

The proposed mega-project would be the world’s largest renewable hub if realised, with a massive 50 GW of solar and wind being used to produce either 3.5 million tonnes of green hydrogen or, alternatively, 20 million tonnes of green ammonia yearly. The $100 billion Western Green Energy Hub, as its called, is being proposed by two of the same companies behind the 26 GW Asia Renewable Energy Hub, which last month had its environmental approvals rejected by the federal environment minister.

Japanese giant Marubeni Corporation is backing Providence Asset Group’s plan for 30 regional projects which will integrate LAVO’s ‘green hydrogen batteries’, a new technology developed at the University of New South Wales.

Global infrastructure developer AECOM has run analysis on every petroleum fuel refinery and storage & import terminal in Australia and New Zealand as a novel means of locating sites well suited to future renewable development and hydrogen industries. “Some sites that were really suited to a wide range of end uses and those were our so-called ‘unicorn sites,’” AECOM’s Craig Bearsley told pv magazine Australia.
