Blockchain for PV module recycling

Next Energy and Marubeni are developing a blockchain tech for PV module inspection – with the support of the Japanese government – which they claim is able to provide data on a panel’s traceability and components as well as verifying that the data were not modified or tampered with.

Corporate renewable PPAs are on the rise in Asia Pacific, says WoodMac

Corporate power purchase agreements are the second most adopted purchasing method in the world, and they’re growing fast. With the U.S. and Europe picking up the pace in the last year, the Asia Pacific is not going to be left behind, with Wood Mackenzie estimating corporate PPAs in the region doubled in the last year.

Lithium-sulfur battery with shorter charging time, longer lifespan

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 revises 2030 targets, plans to double renewables and cut fossil fuels

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.”

Hold your breath for a better battery

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.

Series of ‘flagship’ projects deploying promising new hydrogen technology backed by Japanese heavyweight

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.

WoodMac forecasts Australia’s low-carbon hydrogen export revenue to reach US$90 billion by 2050

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.

Panasonic combines hydrogen fuel cell generators with PV and storage

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.

Panasonic launches 380 W heterojunction solar module compatible with its Evervolt battery

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%.

Australian PV glass developer sets sights on Japanese market

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.
