Solar is the cheapest power, and a literal light-bulb moment showed us we can cut costs and emissions even further
New research suggests we might be able to rethink the type of silicon needed to make high-efficiency solar cells, say researchers from the CSIRO, UNSW and Oxford University.
NT’s first hydrogen-fuelled generator piloted by Charles Darwin University
The Northern Territory is set to install its first hydrogen energy storage system as part of a pilot being operated by the Charles Darwin University in Darwin.
CSIRO steps in to provide expertise for SA natural ‘gold’ hydrogen rush
West Australian natural hydrogen startup H2EX will work with Australia’s national science agency, the CSIRO, to study natural hydrogen systems in South Australia’s Eyre Peninsula, describing the research as a “pivotal first step” for the nascent industry. Natural hydrogen proponents believe projects could deliver some of the world’s cheapest hydrogen quickly and with a minimal footprint.
Cooling down solar modules with cotton wicks immersed in water
The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.
Reverse bias – a hidden challenge for perovskite solar cell stability
Research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.
PV industry needs 12 times more polysilicon production capacity by 2050
New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.
Update: New tech to produce hydrogen from tap water
A Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilises a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.
Construction begins on world’s largest integrated green hydrogen, ammonia plant
In other news, German energy company Uniper said it will test a new salt cavern built for hydrogen storage, while Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen.
Transgrid delivers ‘critical’ interstate transmission project
Network operator Transgrid has completed a $236 million upgrade to the Queensland-New South Wales Interconnector to facilitate the increased flow of electricity between the two states and reduce constraints on the New South Wales transmission network.
Start-up unveils solar thermal panel for large-scale applications
The panel has an absorption area of 1.96 m2 and a weight of 27 kg per square metre. According to the manufacturer – Swiss start-up TVP Solar – it may be a real booster for thermal output, by combining it with photovoltaics and heat pumps to provide enhanced output per square meter, in particular for low-temperature applications such as district heating.
