Remondis Hygrogen Waste Collection truck

REMONDIS Australia’s global breakthrough with zero-emission hydrogen powered waste collection truck

REMONDIS Australia has achieved a global breakthrough by introducing one of the world’s first hydrogen powered waste collection trucks to its operations. After extensive trials, the carbon emission-free truck has participated in its first scheduled residential waste collection in the Illawarra region of New South Wales. The Fuel Cell Electric Vehicle (FCEV) relies on hydrogen which combines with air to generate electricity for motor function. Only water vapour is emitted, and nothing harmful to the environment.

REMONDIS Australia CEO Björn Becker said the truck going into formal operation was historic. “We’re demonstrating that carbon-free transport can and does work in industrial settings,” Mr Becker said. “We’re hopeful that this is the start of a bigger journey whereby companies around the world follow REMONDIS’ lead and turn to fleet decarbonisation. “This should be likely as economies of scale take effect, making the take-up of such technology the norm and not the exception. “REMONDIS has gone all-out to deliver this ground-breaking environmental initiative at the earliest possible time and it’s something we’re very proud of.” REMONDIS NSW South Coast Region Manager Chris Wade said the truck would be fine-tuned through collaboration with its maker, Hyzon Motors, in coming months. “The ultimate aim is to have the hydrogen truck matching our current diesel trucks in all facets,” Mr Wade said. “That includes completing about 1,000 bin lifts over about eight hours. “Trial runs in recent months have been promising, giving us confidence to put the truck into formal operation, serving many of the 300,000 residents in the region. “Putting the truck through full commercial paces will give us additional information and enable adjustments to be made if necessary. “With distinctive markings indicating that it […]

NSW Government seeks to enhance energy savings in hot water system upgrades

The NSW Office of Energy and Climate Change (OECC) has announced several proposed changes to the current Energy Savings Scheme (ESS) for hot water system upgrades. The changes are intended to improve energy savings in hot water system upgrades, ensure consumers have more stake and thus interest in their upgrade process, and align current ‘hypothetical’ energy savings calculations with real world results. Through this exercise, the government hopes to enhance customer engagement whilst also ensuring energy savings are more accurately calculated. Co-Payments: Increasing Customer Engagement Some upgrades under the ESS have required co-payments since 2014. These payments have helped make upgrades under the ESS more accessible to householders and businesses. However, the current $30 (ex GST) co-payment for residential hot water system upgrades and the lack of similar co-payments for small businesses and commercial upgrades have presented challenges. These include reduced customer engagement, perceived lack of legitimacy, and increased instances of high-pressure sales tactics. Efficient Energy Group (EEG) is an Accredited Certificate Provider (ACP) and the company’s CEO Joshua Liptak says the rationale behind co-payments is sound. “They’re there to encourage customer participation in their upgrade projects and help offset the cost of the upgrade. However, the problem for the OECC, and the government, is that when it’s set too low, customers may not be engaged enough to ensure they receive a quality product. Conversely, set the co-payment too high, and it may deter them from getting upgrades done at all. “The effectiveness of co-payments therefore depends on the right balance being struck between these 2 elements, and that’s what these proposed changes are trying to do.” He added, “The current co-payment also doesn’t adequately factor in the high value of the products being installed, which then risks sub par upgrades.” The New NSW ESS Hot Water System Upgrade Co-Payment […]

Shoalhaven business helps lower homeowner energy cost

A Shoalhaven business is working to address the cost of living crisis for households by targeting the energy performance of existing homes across the region. Mantle Sustainable Homes are a Huskisson-based business that specialise in the assessment of energy performance of buildings, and the delivery of advice around how to make those buildings more energy efficient in cost effective ways. “We’re very good at finding opportunities to save money through improved efficiency, even in the oldest of homes” said Mantle Director, Rodrigo Hidalgo. “We can inspect and assess your home by using the best available tools to detect issues like air leaking, thermal bridges, sources of condensation, poor ventilation, or poor performing glazing. Addressing these issues will lower your energy bills”. According to Mantle Sustainable, the Shoalhaven has a large number of older homes that could be easily retrofitted to bring them up to modern standards for energy efficiency. “In every street in every town, we see examples of poor energy efficient design with huge opportunity to improve” said Rodrigo. “Much of our work and recommendations will result in immediate cost savings, while other outcomes will be middle to long term, as we lower energy consumption while delivering a comfortable temperature at home year-round”. Aside from older homes, Mantle Sustainable are also experts in the design and sustainability assessment of projects at any stage, including new builds, renovations and retrofits. Mantle Sustainable partner, Rosario Carrasco, said their mission is to make the Shoalhaven the best region in Australia for energy effiency. “We love where we live. It’s such a beautiful area, with amazing character homes. There’s no reason why the Shoalhaven can\’t become a centre for energy efficiency, to match its natural beauty”.

Australian Hydrogen Council charts way forward for national hydrogen strategy

The Australian Hydrogen Council (AHC) welcomes the Albanese Government’s review of the National Hydrogen Strategy (NHS), and has today offered a comprehensive position paper with 53 key recommendations and supplementary reports to chart a clear way forward. The paper forms AHC’s response to the consultation paper released by the Department of Climate Change Energy Environment and Water on the Refreshed NHS published on 7 July 2023. Much has changed since the original strategy from 2019. The effects of the pandemic and the war in Ukraine have forced a reassessment of how nations consider the strategic overlaps between decarbonisation, national security, and self-sufficiency. In Australia we have also had a change of government, with a new approach to climate change and net zero. Importantly, and as a fundamental outcome of these factors, the US Inflation Reduction Act (IRA) – also a response to these global issues – requires a form of policy response to ensure Australia can continue to attract capital in a competitive environment. Australia cannot match the IRA in terms of the quantum of support, but a targeted policy and funding approach is needed. “All of this is much larger than the question of hydrogen. However, clean and green hydrogen has a key role to play to decarbonise key sectors of the Australian economy, to support the decarbonisation of our trading partners’ economies, and to support our own fuel self-sufficiency. “The lessons learned since 2019 have only amplified the need to focus our attention on how we can best effect the energy transition for Australia,” AHC’s CEO Dr Fiona Simon says. Overall, our position is that the revised National Hydrogen Strategy must be viewed as a key element of the Australian Government’s net zero strategy. This is logical given that hydrogen is itself the means to decarbonise the parts […]

CSIRO’s GenCost report reaffirms wind and solar as Australia’s most cost-effective electricity generation

Renewables, led by wind and solar, have retained their position as Australia’s cheapest new-build electricity generation despite a 20 per cent average rise in technology costs, according to the latest GenCost report. The 2022-23 report marks the first time that all technology costs have increased from the previous year since GenCost commenced in 2018. The report highlights industry concerns that the rapid pace of the global energy transition will contribute to escalating cost pressures. This is attributed to the immense scale of manufacturing, raw materials and labour required to develop and deploy clean energy technologies consistent with net zero goals. GenCost modelling projects that technology cost pressures felt in Australia will revert to normal levels by 2027 but are delayed to 2030 in global scenarios where the speed of the energy transition is highest. GenCost is an annual collaboration between CSIRO and the Australian Energy Market Operator (AEMO) that actively consults industry stakeholders to revise domestic electricity generation and storage, as well as hydrogen production costs. CSIRO’s Director of Energy, Dr Dietmar Tourbier, said GenCost’s rigorous scientific and engineering analysis represents Australia’s most comprehensive projection of electricity generation costs. “Australia’s energy challenge lies in the transformation of our existing energy system, while ensuring the continuing delivery of sustainable, reliable and affordable energy as we strive to achieve net-zero emissions by 2050,” Dr Tourbier said. “This imperative is not only essential for environmental stewardship, but also to maintain Australia’s economic competitiveness in the global market,” Dr Tourbier said. CSIRO’s Chief Energy Economist and GenCost lead author, Paul Graham, said that the COVID-19 pandemic had resulted in lingering global supply chain constraints which impacted the prices of raw materials required in technology manufacturing as well as freight costs. The Ukraine war exacerbated the global supply chain inflationary pressures by raising energy input […]

Out-of-the box thinking lifts mining safety

Hunter Valley-headquartered Hedweld Group of Companies is a recognised global leader in the design, manufacture, and distribution of products for the mining sector. Its niche products have few market competitors. With humble beginnings as a general fabricator in 1980, Hedweld made the business decision in the 2000s to focus on supplying products to the mining sector. Its aim from the get-go was to improve the safety of workers and operators, reduce machine down-time, and increase productivity in mine maintenance workshops. It has been a winning strategy. Kristy Hedley, Managing Director, Hedweld Group of Companies in the Advanced Manufacturing Workshop. Hedweld managing director Kristy Hedley (pictured) says the company’s core competencies of safety, efficiency, and innovation are evident in the Trilift® range of component-handling equipment, and the Safe-Away range of access systems. “As the size of open-cut mining equipment gets larger, accessing the components for maintenance requires greater reach and weight-handling capacity,” says Kristy. “This is where the Trilift range of component-handling equipment offers unique solutions. New mobile mining equipment comes from the OEM factory and is supplied to site with a simple vertical rung or chain ladder to climb aboard to gain access to the operator’s cabin. Our Safe-Away access systems provide a safer way to access and egress.” Hedweld has strong international patents on its Trilift products, allowing it to distribute them globally without fear of competition. “The challenge is educating customers about our unique products and solutions, regularly described as ‘out-of-the-box’ thinking,” says Kristy. “We help sites understand the cost of performing tasks using traditional and often unsafe methods and assist them to calculate and understand that they can’t afford not to use Trilift products – for reasons of safety and cost-saving.” Hunter Manufacturing Awards (HMA) appropriately awarded Hedweld the Export and Supply Chains accolade for 2022.

What is steel scrap and how can it help us reach net zero?

Recycled steel scrap is a low-emitting source of the metal – here’s how we can improve its collection and production to help decarbonise the industry. From bridges to cars to paper clips, steel is ubiquitous in our material world. It is one of the enabling materials that has led to unprecedented living standard rises and progress for humanity. Yet, as with all other emitting economic sectors and material groups, the steel industry needs to decarbonise to meet the climate challenge. Its success as a material means global crude steel production is over 1.9 gigatonnes, but it accounts for an estimated 3 gigatonnes of CO2 emissions annually (albeit this is lower-emitting than most other materials potentially used for the same applications). Steel is made from either primary sources: that is, extracting iron ore from nature and transforming it into pure iron; or from secondary sources, that is, remelting steel scrap into new steel, or a combination of both. This secondary-source steel scrap is the discarded steel that becomes available from manufacturing waste generation and from recovered steel in buildings, infrastructure, equipment, vehicles and products discarded at their end of life. The amount of steel scrap available globally is finite, constrained by the rate of disposal by society. In contrast, the availability of iron ore-based steel is expandable, as mine activity can be increased to meet growing steel demand. There are two principal methods of producing steel. Image: ArcelorMittal Innate circularity Steel has excellent circularity properties. Whereas other materials are often downcycled at their end of life, for many applications, steel scrap can be turned back repeatedly into new steel, retaining its original properties. The magnetic properties of steel make it easy to segregate steel scrap from mixed waste streams. Global emissions from steel are primarily generated while producing steel from primary source iron […]

We could need six times more of the minerals used for renewables and batteries

Rusty Langdon,Senior Research Consultant, Institute for Sustainable Futures, University of Technology Sydney; Elsa Dominish, Research Principal, Institute for Sustainable Futures, University of Technology Sydney. We are seeing the biggest changes in our energy and transport systems since industrialisation. By 2026, global renewable energy generation is expected to match total fossil fuel and nuclear output. Building the wind and solar farms, batteries and electricity networks we need to run our system on renewables will use a huge array of mined minerals, known as “transition minerals”. The numbers are staggering. The International Energy Agency estimates a sixfold increase in demand for these minerals by 2040 to meet climate targets of well below 2℃ of warming. We could need 21.5 million tonnes for electric vehicles and battery storage alone. Transitional minerals include metals such as lithium, cobalt, copper, graphite, magnesium and nickel. They also include rare earths like neodymium, praseodymium, dysprosium and terbium. Currently, mining provides almost our entire supply. The scale of demand for these minerals could result in almost 400 new mines by 2035. To put this in perspective, Australia has around 350 operating mines. More than 50% of the world’s lithium and much of its copper, cobalt, nickel and rare earths come from our mines. Australia is hosting the World Mining Congress this week. A key issue for the industry is how we can ensure the minerals needed for the energy transition are sourced responsibly. How can we manage demand? We can design energy and transport systems to minimise mineral demand. Strategies include: reducing our dependence on cars and using smaller vehicles improving energy efficiency moving to a circular economy that makes reuse and recycling a priority. All these changes can reduce the need for new mines. Recycling, for example, could reduce demand for mined materials. For lithium-ion batteries for electric vehicles, estimated reductions are 25% for lithium, 35% for cobalt and nickel, […]

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 […]
