Rewiring Australia weighs in on nuclear proposal

Electrification advocacy group Rewiring Australia has urged Australia to “double down on electrification”, referring to the finding of AEMO’s Integrated System Plan (ISP) that the country can reliably run on renewable energy, but needs more of it.

“The ISP makes clear that the best course of climate action is to double down on progress made already, support the 3.8 million households with rooftop solar and not U-turn towards slow and expensive nuclear baseload power,” said Dan Cass, Rewiring Australia’s Executive Director.

“Consumer-owned rooftop solar, electric vehicles and batteries from households and businesses have the largest potential for generation, storage and firming capacity by 2050 — more potential than nuclear,” he added.

Cass described rooftop solar as the world’s cheapest delivered energy, with nuclear unable to compete. He said the next step was for governments and industry to coordinate better to deliver large-scale renewables.

“This includes communicating the benefits of clean energy to communities, negotiating with them in good faith and sharing the benefits of clean energy infrastructure more fairly with locals,” he said.

“We also need to focus more on consumers in cities and towns by super-sizing solar and storage on these distribution networks.

“Electrification is the fastest, cheapest and fairest way to decarbonise. We must seize this opportunity to ensure more Australians enjoy the benefits of household electrification as soon as possible,” Cass concluded.

ABB receives EPD status for gearless mill drive ring motor

ABB has gained Environmental Product Declaration (EPD) status for its Gearless Mill Drive (GMD) ring motor — technology used to drive large grinding mills in the mining industry.

An EPD is a standardised document that provides detailed information about the environmental impact of a product throughout its life cycle. Based on a comprehensive Life Cycle Assessment (LCA) study, the EPD highlights ABB’s commitment to transparency, environmental responsibility and supporting customers in making informed decisions on sustainability in their supply chains.

ABB analysed the environmental impact of a ring motor across its entire life cycle from supply chain and production to usage and end-of-life disposal. The study was conducted for a ring motor of a semi-autogenous grinding (SAG) mill with an installed power of 24 MW and was based on a reference service life of 25 years.

“Sustainability is at the core of our purpose at ABB, influencing how we operate and innovate for customers,” said Andrea Quinta, Sustainability Specialist at ABB. “By earning the Environmental Product Declaration for our ring motor, we emphasise our environmental stewardship and industry leadership for this technology. We adhered to the highest standards throughout this process, as we do in the ABB Ring Motor factory every day. This recognition highlights to the mining industry what they are bringing into their own operations when they work with ABB.”

The comprehensive LCA was conducted at ABB’s factory in Bilbao, Spain, and was externally verified and published in accordance with international standards ISO 14025 and ISO 14040/14044. It will remain valid for five years.

The ring motor, a key component of the GMD, is a drive system without any gears where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. It optimises grinding applications in the minerals and mining industries by enabling variable-speed operation, leading to energy and cost savings.

The full EPD for the ABB GMD Ring Motor can be viewed on EPD International.

Bee Hotels Can Help Native Pollinators Recover in the Wake of Climate-Fueled Wildfires: Study

Wild pollinator populations are declining all over the world, with increasingly severe climate change-fueled wildfires threatening their survival. These intense wildfires are also putting long-term ecosystem health and biodiversity at risk. Bee hotels are artificial nesting structures that have been specially designed to house cavity-nesting species. Often placed in backyards or gardens, they provide safe […]
