Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

Japan’s Ministry of Economy, Trade and Industry has released a draft energy plan with ambitious revisions to the nation’s previous energy and emissions targets. The proposed plan will sees a doubling of renewables compared to the previous target, and significant cuts to coal and gas, much of which it buys from Australia. Meanwhile, Australian Resources Minister Keith Pitt reiterated the Coalition Government’s “Gas-Fired Recovery is the right policy for Australia.”

Recent research has revealed a previously underestimated role for oxygen in limiting the performance of lithium-ion batteries. Newly published research from both Japan and the United States has sought to look deeper into the chemical reactions at the heart of lithium-ion storage; and to better characterise the cumulative effects that minuscule amounts of oxygen released during these reactions can have on battery performance and safety.

Japanese giant Marubeni Corporation is backing Providence Asset Group’s plan for 30 regional projects which will integrate LAVO’s ‘green hydrogen batteries’, a new technology developed at the University of New South Wales.

Wood MacKenzie’s energy transition modelling is predicting a primacy in the future low-carbon hydrogen economy for Australia. Thanks to the country’s solar irradiance and renewable energy expertise, as well as its relative proximity to major off-taker markets, Australia could be looking at export revenues of up to US$90 billion by 2050.

The pilot project is combining hydrogen fuel cell generators with a combined capacity of 500 kW with a 570 kW solar array and 1.1 MWh of lithium-ion batteries. It is planned to come online in the spring of 2022.

The new module series has a power output ranging from 370 to 380 W, a temperature coefficient of -0.26% per degree Celsius, and an efficiency of up to 21.7%.

Solar glass developer ClearVue Technologies has once again looked beyond the Western Australia horizon by inking a distribution agreement with Japanese company Tomita Technologies which will see its building integrated PV (BIPV) glazing products sold in Japan.

Giant PV and wind projects are taking shape in Australia’s north, with the aim of supplying Asia with the clean energy it needs for decades to come. The Asian Renewable Energy Hub is one such project, as it targets green hydrogen production at a cost of $1.50/kg. Sacha Thacker, chief strategy officer at InterContinental Energy – one of the companies trying to the get the ambitious initiative off the ground – says that while the scale of projects today boggles the mind, the coming demand is more boggling still.

Canadian Solar is pivoting towards energy storage and is preparing to IPO its manufacturing and Chinese solar project activity in China, under the CSI Solar operation, by July.
