Technology and R&D

Researchers at the University of Wollongong in Australia have discovered a new form of graphene that will improve anode and cathode materials in lithium-ion batteries, making them cheaper and more efficient. They are collaborating with Sicona, which has agreed to buy the researchers’ intellectual property.

The record efficiency was achieved by engineering the cell with reduced copper(II) oxide (CuO) and copper (Cu) impurities in the thin-film deposition. It showed an open-circuit voltage of 1.13 V, a short-circuit current of 10.63 mA/cm2, and a fill factor of 0.696. 

Through three different transactions, AES acquired Community Energy Solar, Stem Inc bought AlsoEnergy, and Enphase took over 365 Pronto.

As Australia stares down a deluge of worn out solar panels, recycling – and indeed upcycling – programs are grinding into gear. In Victoria, a site has been found for Australia’s first facility to recover and reuse solar module materials, while Reclaim PV has extended its manufacturer partner and pickup location lists.

NTPC Limited has selected California-headquartered Bloom Energy’s electrolyzer and hydrogen-powered fuel cell technologies for the nation’s first green hydrogen-based microgrid, which will be powered by a floating solar array.

ESS announced the integration of its long-duration batteries for a microgrid project commissioned by San Diego Gas & Electric to mitigate and increase resilience to wildfires.

Engie unit Tractebel is developing the technology. Elsewhere, the European Commission has approved, under state aid rules, a €900 million German scheme to support investment in green hydrogen production for EU consumption and Spanish company H2B2 Electrolysis Technologies is developing a project to generate up to 1,000kg per day of electrolytic hydrogen in California.

The 600 kW array was built by Sungrow with 540 W solar panels and its own floating structures.

Germany’s TÜV Rheinland is investigating how photovoltaics could be used for powering railway traction networks in a 14-month research project.

Researchers from Tokyo Tech have developed an alternative to hydrogen energy storage which is smaller in size and more efficient. The system utilizes carbon as an energy source and demonstrates superior power density and charge-discharge efficiency of 38% over 10 cycles.
