Energy network must evolve to incorporate renewables more effectively

Australia faces an energy paradox as the country pursues its net zero targets. The Federal Government has enshrined into law an emissions reduction target of 43 per cent from 2005 levels by 2030 and net zero emissions by 2050. This is a significant target, one that industry estimates will require 6 GW of new renewable energy and storage each year. However, the current network is struggling to handle renewable energy fed to the grid, especially from wind and solar farms. A recent study by Australian National University found that solar is the worst affected, with almost double the curtailments compared to wind energy, despite having a smaller installed capacity. This puts the country’s net zero targets under pressure as network congestion is causing large volumes of cheap renewable energy to be curtailed, meaning Australia has an “overgeneration” problem when it comes to renewables, particularly solar. This may lead to financial losses for clean energy generators and make investment in future projects a risky prospect. Regulators face a myriad of challenges in managing a centralised grid – challenges ranging from power outages, modernisation, cybersecurity, demand management and transmission losses. Australian Energy Market Operator (AEMO) estimates that around 10% of the electricity leaving an Australian power station never reaches consumers, which adds to the end consumers’ costs as this lost energy must still be paid for. Grid tariffs are also a concern as they may slow down the country’s path to net zero as renewable energy generators are saddled with legacy grid costs. Grid tariffs are currently based on amortising 25-year investments in national transmission cost. However, renewable energy sources can function cost effectively at the local level using microgrids, which are being implemented across Australia. Kalbarri in WA is now powered by a 100% renewable energy-intelligent microgrid with wind energy, solar […]

Redefining recycling sorting technology with Australia’s first AI-powered robot

A robot that uses artificial intelligence to sort used Tetra Pak beverage cartons has been installed at APR Kerbside’s Material Recovery Facility (MRF) in Truganina, Victoria. Aimed at advancing the circular economy, this innovative recycling sorting technology has been funded via a joint investment between Tetra Pak and APR Kerbside. As part of APR’s future plans, aspirations for upgrade and expansion include the opening of new Material Recovery Facilities in Victoria and the commissioning of additional AI-powered robots to be rolled out over the next two years. In an Australian first, food and beverage processing & packaging company Tetra Pak has partnered with (Australian Paper Recovery (APR) Kerbside to implement an AI robot that can identify, and sort used Tetra Pak beverage cartons. The robot has been commissioned at the APR Kerbside Material Recovery Facility (MRF) in Truganina, Victoria. This glass-out facility has the capacity to process up to 20,000 tonnes of materials annually and mainly sorts items from the kerbside stream. Such items collected from residents’ yellow lidded recycling bins include paper and cardboard, steel, aluminium, plastics (bottles and containers). The robot has been training, learning to recognise all the different types of beverage cartons, like milk, soy, oat, almond, stock and juice ahead of its final deployment in the coming weeks. The councils that are working with APR Kerbside are excited about this opportunity to divert more valuable resources from landfill. They are eager to expand the current kerbside service offering to their respective residents. Darren Thorpe, Managing Director of APR Kerbside. Vikas Ahuja, Sustainability Director at Tetra Pak Australia and New Zealand said: “Tetra Pak is incredibly proud to be pioneering this exciting recycling innovation with APR to further advance the circular economy in Australia. For us at Tetra Pak, to be the first market outside […]

Australia hasn’t figured out low-level nuclear waste storage yet – let alone high-level waste from submarines

Ian Lowe, Emeritus Professor, School of Science, Griffith University Within ten years, Australia could be in possession of three American-made Virginia-class nuclear submarines under the AUKUS agreement with the United States and United Kingdom. The following decade, we plan to build five next-generation nuclear submarines. To date, criticism of the deal has largely focused on whether our unstable geopolitical environment and China’s military investment means it’s worth spending up to A$368 billion on eight submarines as a deterrent. But nuclear submarines mean nuclear waste. And for decades, Australia has failed to find a suitable place for the long-term storage of our small quantities of low and intermediate level nuclear waste from medical isotopes and the Lucas Heights research reactor. With this deal, we have committed ourselves to managing highly radioactive reactor waste when these submarines are decommissioned – and guarding it, given the fuel for these submarines is weapons-grade uranium. Where will it be stored? The government says it will be on defence land, making the most likely site Woomera in South Australia. What nuclear waste will we have to deal with? Under this deal, Australia will not manufacture nuclear reactors. The US and later the UK will give Australia “complete, welded power units” which do not require refuelling over the lifetime of the submarine. In this, we’re following the US model, where each submarine is powered by a reactor with fuel built in. When nuclear subs are decommissioned, the reactor is pulled out as a complete unit and treated as waste. An official fact sheet about this deal states Australia “has committed to managing all radioactive waste generated through its nuclear-powered submarine program, including spent nuclear fuel, in Australia”. What does this waste look like? When Virginia-class submarines are decommissioned, you have to pull out the “small” reactor and dispose of it. Small, in this context, is relative. […]

Sensing the future of energy

Michael Jary – Managing Director, APAC and EMEA, Sense Energy retailer business models have faced extraordinary pressures for over a decade. Even before the war in Ukraine prompted a global crisis in energy markets, retailers were facing a very difficult environment. An inexorable rise in energy costs, together with regulatory intervention and increased customer churn, have eroded retail margins and prompted several exits. Attempts at diversification to adjacent businesses such as home services have often failed because the necessary competencies can be starkly different. At the same time, grid edge intelligence and real-time, appliance-level load disaggregation are generating huge interest in the energy sector. Advances in technology and AI mean that this long heralded technology is now a compelling proposition. Testament to its potential, Sense has recently closed the biggest funding round yet in the sector – a $127m Series C. With millions of next generation smart meters due to roll out with Sense capability in North America, decision makers worldwide are now giving the technology serious consideration for future rollouts. As more than three million Sense-enabled meters begin to roll out in the US, this technology is now coming to Australia, where it can integrate with local smart meters. This is particularly timely, with the Australian Energy Market Commission (AEMC) proposing 100% uptake of smart meters by 2030. Intelligent decisions made today will build an efficient and effective energy monitoring and management system for the future. The benefits to consumers and the energy transition are clear. Sense intelligence represents a powerful tool for reducing both their energy bills and their carbon footprint. It also reduces the overall cost of managing, maintaining, and balancing the energy system. However, the potential to transform retailer business models is what’s seizing the imagination of the industry. So how does Sense intelligence work? Intelligent […]

Women breaking down barriers in engineering

Engineering has long been a male-dominated field, but in recent years, women have been breaking down barriers and making significant contributions to the industry. Australian owned and operated Humiscope, who specialise in controlling indoor environments through energy-efficient solutions, is one example of this progress. However, despite the increasing number of women joining the engineering industry, there is still a significant gender gap. According to the latest statistics from the Australian Bureau of Statistics, only 14% of engineers in Australia are women. This is a concerning figure, particularly when compared to the number of women studying engineering at university. In 2020, 22% of bachelor\’s degree students in engineering were women, which suggests that there is a significant drop-off in the number of women pursuing engineering careers after graduation. There are several reasons for this disparity. One factor is the lack of female role models in the industry. When young women don’t see themselves represented in the field, they may be less likely to consider engineering as a career. Another is that many people are unaware of the myriad industries in which engineering can be applied and the diverse avenues that can be undertaken when studying engineering. In celebration of World Engineering Day, Humiscope champions the importance of recognising women in the field of engineering and wants to showcase the three female engineers on its team. Ladan Bage, a mechanical engineer with a Masters of Science in Mechanical Engineering, works on several large projects for Humiscope. Ladan offers practical mechanical designs while always considering a client’s requirements. She specialises in drafting, documentation, mechanical design, reverse engineering, manufacturing, and its supervision. Ladan works closely with Paula Andrea Gil who is a drafts(wo)men, with a Bachelor’s Degree in Architectural Drafting and Design and over six years’ hands-on experience. Highly skilled in BIM modelling, Paula […]

New process extracts silicon from solar panels to build better batteries

Researchers have developed a sustainable and highly lucrative way to address two big issues in the clean energy transition, reclaiming one of the most valuable elements from end-of-life solar panels and reconfiguring it to build better batteries. More than 100,000 tonnes of end-of-life solar panels are estimated to enter Australia’s waste stream by 2035. Scientists from Deakin University’s Institute for Frontier Materials (IFM) have successfully tested a new process that can safely and effectively extract silicon from old solar panels, then convert it into a nano material worth more than $45,000 per kilo. This nano-silicon is then mixed with graphite to develop a new type of battery anode shown to increase lithium-ion battery capacity by a factor of 10, a critical breakthrough in energy storage technology. Lead researcher Dr Md Mokhlesur Rahman said that for Australia (and the world) to address the enormous issue of solar panel waste and develop a successful recycling program to divert it away from landfill, scientists must find a way to harvest and repurpose the panels’ most valuable components. “Solar panel cells are fabricated using high-value silicon, but this material cannot be re-used without purification, as it becomes highly contaminated over the 25 to 30 years of the panel’s life,” Dr Rahman said. “We have developed a process that returns silicon collected from used cells to greater than 99 per cent purity, within a day and without the need for dangerous chemicals. This thermal and chemical process is far greener, cheaper, and more efficient than any other technique currently on the market.” But it’s the next step that’s the real game-changer. The Deakin process then takes this regular-sized purified silicon and reduces its size to nanoscale using a special ball-milling process. Again, without the need for toxic chemicals. “We are using that nano-silicon to develop […]

Pivotal moment for Australia’s energy future

The Australian Energy Market Commission’s proposal for a 100 percent rollout of smart meters by 2030 is an opportunity for Australia to “build it right” the first time. Philip Crosby was a legendary businessman and management specialist who said it is less expensive to do it right the first time than to pay for rework. His words still ring true today. The Australian Energy Market Commission (AEMC) has embarked on a plan to deliver a more efficient and lower-cost energy system. The Commission believes that smart meters are vital to achieving this goal as they will meet the country’s decarbonisation goals while also building an energy system that will support emerging technologies and services. In November 2022, AEMC released its Review of regulatory framework for metering services. The Commission is proposing a 100 percent uptake of smart meters by 2030 in National Electricity Market (NEM) jurisdictions – a laudable and achievable target. And here, Crosby’s words are particularly relevant. By making intelligent decisions today, Australia has the opportunity to build an efficient and effective energy monitoring and management system – and build it right the first time, without expensive and avoidable rework down the line. It’s time for real time The electricity meter can be the heart of an efficient and effective energy strategy. “Intelligent meters can deliver critical benefits to consumers, grid operators, and energy retailers while future-proofing investments,” says Michael Jary, Managing Director International, Sense. “A smart meter can also improve customer engagement and satisfaction, but crucial to achieving these goals is real-time and detailed device detection, consumption insights, and in-home intelligence,” says Jary. The Commission advocates forming partnerships with new entrants to provide specialised and unique data services and Sense is one of those exciting companies in the intelligent meter space. Sense has developed novel technology that […]

Australia must plan for massive renewables growth to unlock future manufacturing boom

Perth, Western Australia: The Australian Hydrogen Council (AHC) has welcomed the Federal Government’s National Reconstruction Fund amid a renewed focus on domestic manufacturing capabilities but says low-cost renewable energy and hydrogen hold the key to future Australian manufacturing. AHC CEO Dr Fiona Simon will tell over 600 delegates at the Australian Hydrogen Conference in Perth that a national approach to building renewables and other vital infrastructure to produce and use hydrogen is critical if Australia is to gain a competitive advantage in the global energy transition. “This is a long-term play and Australia sits in a prime position to take advantage of the opportunities. But we need a nationally integrated policy that looks to the long term to incentivise domestic manufacturing and open up export markets. “Becoming a ‘renewable energy superpower’ will boost Australian manufacturing in the long-term, providing an economic and national security benefit. Not only can we export hydrogen, we can use it to manufacture direct reduced iron, alumina and fertiliser, both to decarbonise domestic use and to export to other nations. “Economics will favour countries that can transition quickly to low-cost renewables to enable onshore processing and manufacturing for exports. And politics will favour countries like ours that are trusted trading partners, with shared democratic values,” Dr Simon said. “This conference is the key meeting place for Australia’s hydrogen industry and Perth is a strong location given the WA Government’s vision to be a significant producer, exporter and user of hydrogen,” added Dr Simon. Hydrogen industry leaders speaking at the conference include: The Hon Alannah MacTiernan MLC, Minister for Regional Development; Agriculture and Food; Hydrogen Industry, Western Australian Government The Hon Steven Miles MP, Deputy Premier of Queensland, Minister for State Development, Infrastructure, Local Government and Planning, Queensland Government Till Mansmann, Innovation Commissioner for Green Hydrogen at […]

Decarbonise while you Digitalise

Nathan Knight, Hitachi Vantara’s Managing Director for Australia and New Zealand, makes the case for a coordinated approach to decarbonisation and digitalisation. Imagine that manufacturers have a character on each shoulder, one with the word PROGRESS emblazoned across its chest, and the other, SUSTAINABILITY. When deciding where to invest precious resources like time, expertise and money, they can feel like two competing priorities. “Pick me,” says Progress. “More digital services, more automation, more cloud, more diversification, more data analytics, more!” The other voice pleads, “But what about me? You have to consider the planet, responsible resource management, diversification of your staff and your supply chain. You have to reduce your emissions.” Sustainability’s voice is getting louder and more insistent. In the pursuit of digitalisation in the name of progress and competitive edge, the two do not have to be at odds with one another. In fact digitalisation is a powerful tool that can help manufacturers achieve the critical sustainability goal of decarbonisation. Many Eyes on the Manufacturing Sector Australia strengthened emissions reduction targets with the goal of net zero by 2050. According to Grattan Institute, decarbonising Australian industry is an “industrial revolution against a deadline” and the scale and pace of change required is unprecedented. The think tank has called for government policy change, stricter emissions limits and a focus on decarbonising heavy manufacturing and mining, which reportedly produce a third of Australia’s carbon emissions. The heavy industry sector collaborated with decarbonisation experts to form the Australian Industry Energy Transitions Initiative (ETI), which says that regional Australia’s industrial economy could cut greenhouse gas emissions by more than 80% and become centres for multibillion-dollar investments in renewable energy. It would take an unprecedented transformation of the energy system, they say. Acknowledging that the agriculture, mining, manufacturing, data centre and other sectors […]

Keeping blackouts at bay

On June 15 this year, Australian Energy Market Operator (AEMO) suspended trading across the country’s east coast electricity power network as it faced an increasingly volatile situation. AEMO was set up in 2009 and this is the first time the operator took such drastic action across the entire network that it manages. There has been much debate and discussion on the causes ranging from the onset of winter to the war in Ukraine and maintenance shutdowns at power stations. While policy makers, regulators and power generators grapple with the situation, consumers are being asked to better manage their consumption. The conversation is evolving from generating more energy to better managing the energy we produce. With domestic consumption, energy transmission terminates at the premises of the end consumer. In the current situation, a lot is being asked of this often-neglected group. They are being requested to reduce consumption by shutting down appliances in certain times or use them outside peak periods. Customers have also been warned about potential blackouts. Current policies around demand management are focused on industrial plants and other large energy consumers, and these are governed by clear policies and processes. Consumers meanwhile are bracing themselves for energy price hikes and power cuts. Fortunately, technology has advanced and, when implemented, can give consumers more visibility and control over their energy usage. A good example is Sense, which has developed AI that runs on smart meters. Over two million Sense-enabled meters have been announced in the US and this technology is now coming to Australia. Their machine-learning algorithms can assess domestic electricity right down to the appliance level in real time. According to a directions paper released by the Australian Energy Market Commission (AEMC), only 25 per cent of premises in New South Wales, Queensland, South Australia and the ACT […]
