Australian-made green plane fuel closer with grant win
The innovative project, undertaken at the University of NSW, has won a $1.2 million grant to progress the technology and scientists say a prototype could be as little as six months from launch.
The announcement on Thursday comes amid increasing demand for sustainable aviation fuel in Australia and worldwide and follows the launch of several multimillion-dollar projects designed to turn waste into jet fuel.
Sustainable aviation fuel, or SAF, is typically made from agricultural waste such as sugarcane, tallow, canola and cooking oils and can reduce emissions from aircraft by 80 per cent compared to traditional jet fuel.
But the UNSW project deploys an electrolyser that uses low-cost metals, carbon catalysts and renewable energy to turn carbon dioxide and water into fuel precursors.
The approach could cut out the need for farm waste and make environmentally friendly fuel easier to produce at scale, project leader Rahman Daiyan said.
"Most of the work so far has been on bio-based sustainable aviation fuel projects," he told AAP.
"But those sort of biomass resources are limited to some extent."
The Trailblazer for Recycling and Clean Energy program, established by the federal education department, has awarded the UNSW research team an additional $1.2 million to scale up its technology.
While the electrolyser has been proven to work in a lab, Dr Daiyan said a validated prototype would be ready within six to nine months, and the project would be commercialised with industry partners Tjindu Power and Chinese energy firm Chuangqi Times.
If successful, he said, the project could help to realise Australian ambitions to become a green fuel exporter.
"One of the best aspects of this technology is that it allows us to leverage Australia's potential – we want to be a hydrogen exporter or a low-carbon fuel exporter," Dr Daiyan said.
"There is domestic demand but there is also overseas demand because apart from Singapore and Malaysia there are not a lot of places to make SAF for the Asia Pacific region."
Sustainable aviation fuel is considered to be one of the leading ways to reduce carbon emission from air travel and is in high demand worldwide after major airlines committed to using the fuel to achieve net-zero emissions by 2050.
A report by the CSIRO and aircraft maker Boeing, released in November, found Australia could lead the world in production of the sustainable fuel but warned it had made only moderate progress so far.
Sustainable aviation fuel projects are under way in Queensland and Western Australia, including a refinery planned by Wagner Sustainable Fuels and plans to transform BP's Kwinana Energy Hub in Western Australia.

Power giant warns of ‘two-speed' green shift which benefits only the rich
Millions of Australians face being left behind in the race to greener energy, one of the nation's largest power distributors has warned, as renters miss out on huge savings from solar panels while homes without off-street parking cannot install electric vehicle chargers. From this year, home-owners with solar panels stand to benefit from even bigger electricity bill cuts following the introduction of federal government rebates wiping thousands of dollars off the cost of installing batteries that can soak up their excess energy. Increasing home battery uptake has many advantages: it will enable Australia to harness more of its world-leading per-person solar panel uptake to use after sunset, drive down greenhouse gas emissions and smooth out volatile price swings across the market. But the household clean energy boom may create winners and losers, warns Ausgrid, the largest power distribution company on Australia's eastern seaboard. The company points to renters and lower-income Australians who are unable to make the switch and are forced to stay on increasingly expensive fossil fuel-based energy supplies. 'The problem we see is that if you don't own your own home, or have the financial wherewithal, you are faced with the full system cost of the transition,' said Rob Amphlett Lewis, Ausgrid's group executive of distributed services. Loading 'What we are in danger of is a two-speed transition that works for the 'haves' and is paid for by the 'have-nots'.' Ausgrid and other Australian distribution network service providers are seeking to expand their reach beyond building and maintaining the network's poles and wires and into other future-facing functions where they believe they are well placed to deliver more efficient outcomes for consumers. Their push, however, has opened a major new rift in the industry between network operators and a wide range of other electricity market participants, which are urging regulators against any waiver from 'ring-fencing' rules designed to prevent monopolies from encroaching on competitive markets, and argue it could drive up costs.

Private R&D investment by Australian businesses falling, report finds ahead of roundtable
Private investment into research and development in Australian businesses is slipping backwards and comparatively lower to similar other nations, a new report shows. The report — collated by the Business Council of Australia ahead of Treasurer Jim Chalmer's productivity roundtable next month — identified a raft of targeted policies to boost business potential. It proposes offering extra incentives for collaboration and commercialisation, cutting red tape, and consolidating grants into major national programs. The report estimates that for every $1 spent on R&D, it generates $5 in economic value and $7 billion in gross domestic product (GDP) annually. If the suite of measures are implemented, it's expected to grow productivity in Australia 0.1 per cent each year. It also recommends a simpler R&D Tax Incentive by standardising tax offsets of 18.5 per cent above the company rate and removing its current $150 million cap. It's hoped having a single, consistent rule rather than the current different benefit rates depending on company size or how much they spend, would encourage firms to invest in R&D, especially smaller players. As for scrapping the cap, the policy is designed to allow businesses to claim tax offsets for all of their eligible R&D spend rather than just the first $150 million under the current framework. BCA chief executive Bran Black said the targeted policies were designed to fix Australia's productivity problems by unlocking investment, boosting jobs and wages. He said reversing the current trend, which has seen R&D investment drop 24 per cent in the last decade, would help drive innovation and productivity nationally. He said it was important businesses were given the 'right environment' to invest: 'If we don't act now then we will keep losing innovators, capital and ideas to other nations'. 'Better tax, collaboration and commercialisation policies will give businesses the confidence to take the next step and create new Australian technologies that benefit everyone's lives,' he said. The report will form part of a joint industry submission with well-known Australian software firm Atlassian and medical device company Cochlear. Cochlear chief executive and president Dig Howitt said policy reform and 'well-funded strategies' would be critical to unlocking more R&D in Australia. Atlassian chief of staff Amy Glancey said by supporting major companies to invest in R&D it would have a trickle down effect to create a better environment for entrepreneurship and innovation. Dr Chalmer's roundtable will be held at Parliament House August 19–21 and is expected to shape a shared agenda on improving productivity, strengthening budget sustainability, and building economic resilience. It has prompted a number of state-level consultations and spin-off roundtables, including one held on Friday by Independent MP Allegra Spender involving economists and industry figures in Canberra. The BCA, along with other industry bodies, companies, and government representatives, are finalising submissions ahead of the August roundtable, outlining ideas across tax, regulation, innovation, skills, and digital transformation to help lift Australia's productivity.
