After-dark energy supply - a potential winner?
Victoria's RayGen is a finalist in the InnovationAus 2023 Awards for Excellence for its thermal energy & storage innovation. It involves a field of mirrors, used to focus sunlight onto a receiver tower with solar modules that generate electricity. Water is also pumped up and down the tower, capturing the heat in a pit of hot water nearby. This water is then used to drive a turbine and generate electricity. RayGen, based in Melbourne, has projects in regional Victoria, SA and NSW.It's backed by Equinor Ventures, SLB, Chevron Tech Ventures, Photon Energy Group, AGL Energy & Australian Gov. https://www.innovationaus.com/the-solar-thermal-storage-pioneer-capturing-energy-after-dark/

Essential shifts in Food & Agriculture - for a green future
Participants in the World-wide food chain—including farmers, agribusinesses, processors, and distributors—have made great strides in increasing overall 'caloric availability'. However, they have not yet overcome environmental challenges associated with food and agriculture. In 2019 the world’s agri-food systems accounted for about 30 percent of human-caused global greenhouse-gas (GHG) emissions, making them a critical focus for meeting increasingly bold climate targets.Five major shifts are needed to support the goals of 21st-century food and agriculture: building land value, fueling the biorevolution, eating sustainably, ESG accountability, and taking out the waste.This McKinsey article articulates these shifts:

pA Photocatalytic water splitting reactor
Adelaide-based Sparc is prototype testing its photocatalytic reactor technology to split water into its constituent hydrogen and oxygen molecules at CSIRO’s Energy Centre in Newcastle, New South WalesThe photocatalytic water splitting technology is expected to deliver cost and flexibility advantages over green hydrogen projects that use electrolysers or solar farms, given the lower infrastructure and energy requirements.Sparc executive chair Stephen Hunt said this is “a world leading demonstration of photocatalytic water splitting in a concentrated solar field"https://www.innovationaus.com/adelaide-uni-fortsecue-hydrogen-venture-starts-testing-prototype/

Reducing aircraft contrails - to fight global warming?
American Airlines have recently demonstrated what could be the world's cheapest way to fight global warming. Working with Bill Gates' Breakthrough Energy Group they have shown that avoiding “ice supersaturated regions” of the atmosphere where long-lasting airline contrails can form, they can significantly reduce their warming impact.Marc Shapiro, the head of contrails at Breakthrough Energy, said this is the “highest-leverage climate opportunity that we know of,” the equivalent of removing carbon from the atmosphere at a cost of 10 dollars per ton or less. And it will be standard practice in the very near future.https://qz.com/american-airlines-contrail-technology-global-warming-1850792287

Roof-top Solar Rules!
Despite news of reduced electricity reliability and the Snowy Hydro project delays, the consumer (and roof-top solar) has become a powerful player in the Australian market, and is probably the biggest factor in chasing coal out of the grid. And, as we add batteries, electric vehicles, and kick gas out of the home with electrification we are reshaping the grid, the utility business and the gas industry.If this can be better “orchestrated”, then the reliability forecast will be improved considerably and less utility scale assets – big batteries, pumped hydro, and peaking gas – will be needed.https://reneweconomy.com.au/rooftop-solar-takes-even-bigger-bites-out-of-diminishing-coal-pie-but-can-it-be-con

Rachel's Farm-a film about farm regeneration
A new film about Regenerative Farming and (judging by the trailer) a very appealing plea for revolutionary agriculture. From Hoyt's Synopsis:"Film director and Actress Rachel Ward is not the first person you’d expect to join a farming revolution. In this triumphant film, Rachel voyages from wilful ignorance about the ecological impacts of conventional agriculture on her own rural property, to embracing a movement to restore the health of Australia’s farmland, food and climate"Launched at the Sydney Film festival, this film is touring country cinemas and should be on wider (streaming) distribution soon.https://thenewdaily.com.au/entertainment/2023/08/01/rachel-ward-farm/https://www.madman
