Japan’s Rinnai has unveiled what it claims is the world’s first 100% hydrogen combustion technology for residential water heaters. It is currently using the hydrogen water heater in demonstration projects in Australia, prior to commercialisation.

Australia’s uptake of rooftop solar is one of the highest in the world with more than 30% of free-standing households across the nation now fitted with a PV system but the Clean Energy Regulator has revealed a “steep decline” in the number of installations in early 2022 with deteriorating economics playing a major part.

Solar installers and resellers can now access up to $250,000 on interest-free terms to increase their stocks of Australian-made solar panels after PV module manufacturer Tindo Solar teamed with business financer Moula Pay.

Scientists in the United States have developed a new model to allow utilities to use grid-forming inverters in order to better manage renewable energy intermittency. They describe the inverter main circuit representation, the droop control, and the fault current limiting function.

The Queensland government has committed $48 million to progress two pumped hydro projects in the state, declaring energy storage will play a critical role in its push towards a renewable energy future.

Swiss module manufacturer Megasol has unveiled a novel rooftop PV system in two variants — full-black and translucent. The installation consists of vertical supports, a ridge profile, and solar modules.

The battery has a rated output of 5.5 kW and can be installed in outdoor environments. It is equipped with a hybrid power conditioner, a DC-to-DC converter, and a vehicle power supply adapter with a maximum output of 1.1 kWh.

The rollout of rooftop solar in the western suburbs of Melbourne is set to get a boost with Victorian network service provider Powercor identifying the site where it will install a community battery that is expected to unlock more than 129MWh of solar PV hosting capacity.

The New South Wales government has announced its single biggest investment yet in renewable energy infrastructure, committing $1.2 billion to fast-track priority transmission and energy storage projects as the energy sector continues its rapid transformation towards a decarbonised and decentralised future.

Buildings-integrated photovoltaics maker Mitrex plans to deploy highway noise barriers with integrated solar that have 1.2 MW of capacity per kilometer. The technology is currently in the pilot phase at government entity locations in North America.
