Australian researchers have analysed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

The Federal Government has added a new element to the National Electricity Market (NEM) equation by announcing it will provide up to $11 million to help progress the CopperString 2.0 transmission project in Queensland.

Chemical engineers at the University of New South Wales and the University of Sydney have made a significant technological breakthrough in the development of green ammonia. The breakthrough could not only alter the global ammonia industry, but more easily use solar to produce green ammonia for export to countries like Japan and Germany instead of straight hydrogen.

Hydro Tasmania and buyers Macquarie Group and ERM Power have signed a ‘Virtual Storage’ deal which will see the pumped-hydro company sell the rights to its highest priced periods of ‘discharge’ and buying a fixed MW block of low-priced ‘charge’. The innovative contract is the product of the ARENA-funded Renewable Energy Hub.

Unlike other nations with more limited land and faster growing populations, Australia has not yet understood the symbiotic benefits which accrue when solar PV and agriculture are combined. This week, the Victorian Government announced its Horticulture Solar Energy program and $5 million in funding for the Tatura SmartFarm to experiment with solar atop a pear orchard.

Two outages at coal fired power generators in Victoria last weekend failed to faze the energy market as strong solar uptake ensured wholesale prices actually fell into the negative despite major units going offline at the height of summer.

Throughout 2020, a fast-moving story played out in PV module technology, with the introduction of larger wafers and subsequently larger module formats seeing the industry break into two camps, backing either 182 mm or 210 mm wafers. It remains to be seen whether one or the other will become a new industry standard, and both sizes will likely be plentiful on the market for the next few years at least. pv magazine takes a look at how we got to this point.

Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.

Researchers at the Australian National University (ANU) will look to “set the pace” with the development of next-generation solar cell technology after receiving a $4.5 million funding boost.

Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that is claimed to reduce cleaning cost by around 60%. The anti-reflective and anti-corrosive coating is also said to mitigate potential-induced degradation (PID).
