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 […]

Reducing plastic waste at Christmas

A world-first open platform to help reduce plastic waste and encourage sustainable solutions is being launched in time for the biggest waste dump of the year – Christmas. With approximately 30 per cent more waste produced at this time of year, now is the perfect time to start. I’M PLASTIC FREE www.implasticfree.com is a free platform to find eco services and products for consumers and businesses and provides up-to-date independent research – no greenwashing – and information for living more sustainably and ethically. Its values are simple: all materials and products are treated with value, and the circular economy is an integral part of our everyday life. ‘If every person made one or two easy changes using eco-friendly materials instead of single-use plastics, the impact would be enormous,’ says founder, Simona Paganetto. ‘Reuse and repurpose are first so there’s no waste, but when it’s time to replace your item, we provide a platform that makes finding and choosing an alternative easy.’ At Christmas this can really add up. Australians use an average of eight metres of paper for Christmas gifts. That might not sound like much, but it adds up to around 150,000 kilometres of wrapping paper. Enough to circumnavigate the globe four times. ‘We’re talking about something that is just ripped away and discarded, and if it’s got any type of foil or shine on it, it can’t be recycled,’ says Simona. ‘Don’t forget the ribbon and tinsel too, which are made from plastic.’ A different approach can make a huge difference. ‘Firstly, reusing paper, ribbon and tinsel is great,’ she says, ‘but if you don’t have any to reuse, there are many alternatives.’ I’M PLASTIC FREE has a handy Christmas checklist to help. ‘If every Australian family wrapped just a quarter of their presents in reused or alternative-paper […]

Four easy ways to make your office greener

As more businesses choose to go green and be environmentally responsible, the process can seem a little overwhelming given the plethora of greening solutions. Below are four easy ways to go green in the office, and save money and achieve efficiencies in the process. 1.Eliminate the printing of forms We are all too familiar with filling in office forms. Typically, these are often supplied in a paper format, and completed and signed manually before being returned to their point of origin. The process is both time and resource intensive. According to the National Waste Report 2020, prepared for Australia’s Department of Agriculture, Water and the Environment by Blue Environment Pty Ltd, 5.9 Megatonnes of paper and cardboard waste was generated between 2018-2019 in Australia.1 Paper manufacturing leads to deforestation, increased carbon emissions and climate change. The use of paper can also be operationally expensive for firms. Apart from the cost of the paper itself, once the completed paper forms have been processed, they are usually assigned to the inevitable – filing cabinets and storage facilities – which add to operational costs. Software solutions however, can eliminate the need for paper forms and help your office go green. Common software programs such as Microsoft’s Word allow you to quickly and easily create digital forms. Better still, software solutions such as Kofax Power PDF, let you convert the form into a PDF for greater flexibility and collaboration. Power PDF even converts images into fillable PDF forms. Colleagues can then easily access the PDF form to quickly complete details, highlight data, or leave comments. And the software’s inbuilt digital signature capability lets businesses capture signatures electronically. What’s more, the forms can then be filed electronically and also integrated directly into document management systems. This negates the need for filing cabinets and physical storage […]

Victorian opposition recognises gas for cleaner energy future

Australia’s oil and gas industry has noted the return of a balanced discussion about Victorian energy policy, with recognition from the State Opposition that natural gas is central to the cleaner energy future. The Australian Petroleum Production & Exploration Association (APPEA) today said Opposition Leader Matthew Guy’s pledge to end natural gas bans and use the energy source to replace coal and partner with renewables on the road to net zero was a sensible position backed by experts. APPEA Chief Executive Samantha McCulloch said: “This position understands the fundamental energy system changes occurring globally – with natural gas widely acknowledged to have a central, and even wider, role in the future energy mix than it does today. “Natural gas will replace higher emitting coal and firm renewable power generation, support manufacturing, help make everyday products as well as act as a feedstock for hydrogen. “As the Federal Government’s special adviser on low emissions technology, former chief scientist Dr Alan Finkel, said recently, gas can even speed up the journey to a cleaner energy future.” Ms McCulloch said Mr Guy had called out the untenable position of Victoria relying heavily on coal-powered electricity while having minimal onshore gas production because of a decade of development bans, which have deprived Victorians of the cheapest gas available to them. “Victorians currently pay $2 extra for every gigajoule of gas to be transported from Queensland under this policy, which ignores the fundamental rule that the cheapest gas is the gas produced closest to the customer,” she said. “The industry has announced over $20 billion of new supply investments over the past two years. But little of that has been in Victoria because of a decade of uncertainty, moratoriums and bans. We need certainty and the investment policy settings to be right. “As well as […]

Crucial role for gas for decades

Gas will play a crucial role for decades as a stabliser for the electricity grid in a cleaner energy future, according to a new 30-year roadmap by the national energy market regulator. The Australian Petroleum Production & Exploration Association (APPEA) today said the Australian Energy Market Operator (AEMO) had confirmed the long and enduring value of natural gas partnering with renewables with the release of its 2022 Integrated System Plan (ISP). APPEA Acting Chief Executive Damian Dwyer said the Plan showed the key role of gas as the world decarbonises by citing the mid-2040s as a time when gas would back up electricity largely powered by renewable generation after the retirement of coal-fired power. “As a sector strongly committed to economy-wide net zero by 2050, the oil and gas industry recognises the growth of renewables and the importance of multiple energy sources working together to ensure the power generation sector can continue to decarbonise,” Mr Dwyer said. “The plan confirms the central role of gas in that future as a reliable and flexible stabliser for renewable power generation when the wind doesn’t blow and the sun doesn’t shine. “Coal won’t get you to the goal and this plan details how gas will step up and take over from coal and also be a cleaner source of energy in the grid.” Mr Dwyer said this firming role was exemplified in the Plan’s modelling showing how gas would be needed during low and high outputs of renewables during peak demand periods. “Even at a period of high renewable output, AEMO says gas will be required to firm renewables during high demand just after sunset and through the night to cover wind variability,” he said. Mr Dwyer said the need for rapid gas during recent energy system pressures – when coal outages combined […]

Henkel Australia powers adhesive sites with 100% renewable energy

Henkel Australia has begun using electricity generated fully from renewable energy sources at its adhesive plants in Seven Hills, New South Wales, and Kilsyth, Victoria. The adhesive plants serve a wide range of industries, such as flexible packaging, engineered wood, food and beverage, steel, paper, mining, and maintenance, repair and overhaul. Thanks to more than 2,000 solar panels on their rooftops and renewable energy contracts, the sites are expected to realise more than 50 percent savings in carbon emissions in 2022, compared to last year. “Globally, Henkel is accelerating its climate actions. In line with this, we have successfully switched to using 100 percent renewable electricity to power our adhesive plants in Australia. In tandem, we are exploring more ways to improve energy efficiency and decarbonise our operations as we progress towards becoming a climate positive company,” said Daniel Rudolph, President of Henkel Australia and New Zealand. To optimise energy consumption and drive energy savings, new boilers, air compressors and scrubbers that come with variable speed drive (VSD) smart controllers are being used. Passive infrared (PIR) motion sensors are also being installed. Henkel is pursuing ambitious goals to make its production processes climate positive by 2030. By 2025, the company aims to reduce the carbon footprint at its sites worldwide by 65 percent compared to the base year 2010. Furthermore, the electricity used is to be generated 100 percent from renewable sources by 2030.

Study to research opportunity of carbon capture and storage in WA

A new study investigating opportunities in Western Australia for carbon capture, utilisation and storage (CCUS) and carbon capture and storage (CCS) is a positive step in finding pathways to decarbonise the economy, according to Australia’s oil and gas industry. The Australian Petroleum Production & Exploration Association (APPEA) today backed the study commissioned by the Western Australian LNG Jobs Taskforce, supported by APPEA members bp, Chevron, Eni, Santos, Shell, and Woodside. APPEA WA Director Claire Wilkinson said the research would provide critical intelligence on how best to deploy CCUS and CCS to decarbonise not just the state’s gas industry but many other sectors as well. “The oil and gas industry is committed to achieving net zero greenhouse gas emissions by 2050, with several companies targeting even earlier timeframes,” Ms Wilkinson said. “Decarbonising our existing and future operations means there is a need to invest in renewable energy and lower emission technologies and this study will help inform the investment opportunities in this space. “CCUS and CCS have key roles in lowering the carbon intensity of gas production and in supporting the development of a blue hydrogen industry here in WA, a key enabler to a viable hydrogen industry. “The study will help us chart a way forward with natural gas set to be a key part of a cleaner energy mix.” The study will be conducted by the CSIRO and the Global Carbon Capture & Storage Institute and is expected be completed in the second half of this year. The Western Australian LNG Jobs Taskforce aims to maximise local jobs and establish WA as a global LNG hub. Originally established by the WA Premier in 2018, it comprises of the Minister for State Development, Jobs and Trade; heads of Woodside, Chevron, Shell, Santos, and INPEX, and representatives from APPEA and UnionsWA.

Eraring set to close seven years early in 2025

Chris Briggs,Research Director, Institute for Sustainable Futures, University of Technology Sydney In a major step forward for Australia’s clean energy transition, the country’s biggest coal-fired power station Eraring is set to close seven years early in 2025, Origin Energy announced this morning. Eraring has been operating for 35 years in the central coast of New South Wales. Last year, it alone was responsible for around 2% of Australia’s greenhouse gas emissions, based on calculations from electricity market and emissions data. The fundamental reason for its early closure is the brutal impact the growth of renewable energy is having on the profitability of coal plants. Origin has announced it will be building a large, 700 megawatt battery on-site in its place to store renewable energy. This announcement follows the acceleration of other major coal plant closures: Liddell power station is scheduled to close in 2023, Yallourn’s closure was brought forward to 2028, and only last week AGL Energy edged forwards the scheduled closure of two more coal plants. This is a welcome step with transition planning by Origin – but also underlines the risks of Australia’s clean energy transition accelerating without a national plan for the exit of coal. Why is this happening? Old power stations are excellent sites for batteries due to their existing connections to transmission lines and lots of electricity capacity. This has also been announced for the closed Hazelwood and Wallerawang coal power stations. Over the past 12 months, the market share of renewable energy has increased to over 30%. In particular, the rapid growth of rooftop solar and solar farms in the middle of the day has sent daytime wholesale electricity prices crashing. To stay open, coal plants are using a variety of coping strategies. This includes cycling their output down on sunny days and ramping back up for higher prices as the sun sets and demand increases at the end of […]

How the budget can deliver economic recovery and cleaner, secure energy

Australia’s oil and gas industry has urged the Federal Government to use the 2022-23 Budget to encourage continued investment in secure, cleaner energy. In a plan to bolster the investment environment, the Australian Petroleum Production & Exploration Association (APPEA) said development of both the natural gas industry and new technology could drive economic recovery, create jobs and reduce emissions. APPEA’s 2022-23 Federal Budget submission, released today, calls for economy-wide investment allowances for large projects and new technology initiatives cutting carbon emissions; the immediate deductibility of wages and salaries; as well as the removal of barriers to oil and gas project restructuring. The blueprint also includes expanding the Junior Minerals Exploration Incentive (JMEI) for junior oil and gas explorers to secure additional local supply for the future. New net zero initiatives include amending the Offshore Petroleum and Greenhouse Gas Storage Act 2006 to allow for reservoir testing for the examination of CCUS use as well as supporting carbon capture opportunities through acreage releases.  APPEA Chief Executive Officer Andrew McConville said the industry was key to securing Australia’s competitive advantage through its work ensuring energy supply and decarbonising for a cleaner energy future. “This is a plan that delivers cleaner, secure energy supplies while lifting us out of the tough times of the pandemic,” he said. “Australia and its government have a massive, once-in-a-generation opportunity to make policy decisions to provide foundations for the future growth of our economy. “A recent Ernst & Young report found national economic output could rise over $350 billion and create over 220,000 jobs in the next 20 years – but only if the settings are right. “And, of course, our industry will continue to deliver taxation revenue that helps to build the nation’s roads, schools and hospitals.” The full suite of APPEA recommendations to be […]

Rio Tinto purchases first battery-electric trains for the Pilbara

Rio Tinto has agreed to purchase four battery-electric trains for use in the Pilbara region of Western Australia as part of the company’s strategy to reduce its carbon emissions by 50 per cent by 2030. Rio Tinto purchased the four 7MWh FLXdrive battery-electric locomotives from Wabtec Corporation with production due to commence in the United States in 2023 ahead of initial trials in the Pilbara in early 2024. The locomotives, used to carry ore from the company’s mines to its ports, will be recharged at purpose-built charging stations at the port or mine. They will also be capable of generating additional energy while in transit through a regenerative braking system which takes energy from the train and uses it to recharge the onboard batteries. A full transition to net zero emissions technology of its entire fleet of rail locomotives would reduce Rio Tinto Iron Ore’s diesel-related carbon emissions in the Pilbara by around 30 per cent annually. Rio Tinto Managing Director of Port, Rail and Core Services Richard Cohen said delivery of the prototype locomotives will be an important early step for the company on the path toward a decarbonised Pilbara. “Our partnership with Wabtec is an investment in innovation and an acknowledgement of the need to increase the pace of our decarbonisation efforts. “Battery-electric locomotives offer significant potential for emissions reduction in the near term as we seek to reduce our Scope 1 & 2 carbon emissions in the Pilbara by 50 per cent by 2030.” Rogerio Mendonca, President of Freight Equipment for Wabtec, said the FLXdrive is ideally suited to support Rio Tinto’s decarbonisation targets. “This locomotive provides the power, fuel savings and emissions reductions to cost-effectively run rail networks in the mining industry. The rapid adoption of the FLXdrive by Rio Tinto and other mining operators demonstrates […]
