Technology and R&D

Western Australian ocean energy company Bombora Wave Power has received an investment of $6.74 million to deliver its pilot projects and commercialise its technology from one of the world’s largest shipping companies, Japan’s Mitsui O.S.K. Lines.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

U.S.-based hydrogen vehicle maker Hyzon has announced Melbourne will soon be home to its Australian headquarters as part of a newly formed partnership with RACV, which will see the pair develop a purpose-built facility for Hyzon out of RACV’s Noble Park operation in the city’s south east.

Once thought of in a niche sense, the solar-water nexus is a rapidly expanding network of applications. They include practical tools capable of solving persistent issues like water scarcity, as well as newly pressing issues like overcoming the water challenge of green hydrogen production. Blake Matich looks at such applications here in Australia and abroad.

Lavo’s hydrogen battery technology has found monetary support from both Australian and international investors in the last year, as well as public support which has continued this week with the announcement by the New South Wales government of $5 million in funding from the Regional Job Creation Fund to boost hydrogen manufacturing jobs in the Hunter Region.

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

Scientists in Australia have analysed the state-of-the-art of all gettering technologies used in the solar industry. This technique, which is aimed at reducing defects in wafer manufacturing, may become more important in the future, as cell efficiencies increase and become increasingly sensitive to traces of metallic impurities.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm2, they achieved a record efficiency of 25.7% and high operational stability.

A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.

Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.
