At the University of Newcastle hydrogen production starts with water extracted from the atmosphere and electrolysis powered by free energy from the sun; sucking CO2 from the air is the next step to filling Angus Taylor’s beloved gas infrastructure with green methane that can bring spuds to the boil and power the economy while helping to flatten the nation’s emissions curve.
New analysis from The Australian National University along with recently published figures from the Clean Energy Regulator demonstrate that Australia remains the world leader in wind and solar deployment per capita, particularly rooftop PV. However, federal policy is failing to invest in desperately needed infrastructural upgrades.
A University of South Australia study has demonstrated that while solar panels in Australia are typically installed facing north to catch most of the sun’s arc, if you’re looking to export your solar into the grid you should really be orientating your panels to minimise the discrepancy between the times of peak use and peak production.
Scientists in Australia took a close look at the long-term performance of passivation layers in silicon solar cells, and discovered a surprising process of degradation and regeneration at work within the material. The results could have implications on the processes used in industrial scale solar cell production.
Western Australia’s Recovery Plan continues to grow greenery as more renewable aspects of the state’s stimulus package come to light, specifically solar light that is. The state government has committed $22 million toward nine green hydrogen initiatives across the state, while also bringing forward its Renewable Hydrogen Strategy targets a decade and topping up the green hydrogen fund.
Big batteries derive most their value from replacing gas peaker plants and averting the installation of excessive amounts of transmission and generation infrastructure. However, batteries cannot replace all gas plants, MIT researchers found. From a holistic economics perspective, there is a certain share of storage that is considered cost-efficient. With battery costs declining, that share is constantly increasing.
Researchers from India’s Centre for Nano and Soft Matter Sciences have developed a coordination polymer-based catalyst for hydrogen production that exhibits exceptionally high durability for 70 hours at a high current density of −300 mA/ cm2.
Researchers built the device by attaching 17%-efficient monocrystalline PV cells to a mortar roof tile that was doped with a phase-change material (PCM). The PCM solar tile provided 4.1% more power than the PV tile with no cooling agent in the winter, and 2.2% to 4.3% more during the summer.
With the disruption of Covid-19 highlighting the climatic impact of the aviation industry, a recent report from the CSIRO funded by Boeing shows that hydrogen fuel’s technological momentum could see clean hydrogen used in airports by as early as 2025, and a full transition from conventional jet fuel by 2050.
Scientists in India have taken a close look at the potential impact of growing volumes of PV waste, and have conducted surveys that suggest a lot more work is needed from manufacturers and policymakers to develop management systems for end-of-life PV products.
