The safety and cost benefits of an autonomous mining industry

Gaurav Sharma, Head of Industries Business for ANZ, Cognizant Employee safety is a major concern for Australian mining corporations. Even today, with arguably the best mining safety regulations in the world, there continues to be serious injuries and sometimes fatalities. Fortunately, the industry is in a good position to address these concerns with the help of technological advancements in automation. The benefits of automation stretch beyond safety McKinsey estimates that digital innovation in the mining industry can be worth $370 billion per year worldwide in 2025. A key element of digital innovation is automation ― automation of operating equipment, technology functions, and business processes. Already Australia is a world leader in mining equipment automation, including automated trucks, drill rigs, trains and port operations. Implementing automation across various facets of the mining industry can improve safety and improve productivity. While autonomous mining equipment requires companies to inject significant capital, it is balanced by lower operating costs. Automating mining equipment including haul trucks can mitigate the danger of driver fatigue and boost the efficiency of long-haul transportation, adding much more value to the supply chain of the industry. Sensor technology is now so advanced that autonomous trucks could sense even the smallest of hazards — like a bird flying in front of it — and react accordingly. The future has already arrived for autonomous driving in the sector Autonomous operations are now a working reality within the Australian mining sector. One of Australia’s leading mining corporations is a world leader in autonomous mining equipment technology. Since deployment, the company has had zero injuries, highlighting the major safety and productivity benefits that autonomous mining trucks provide. Are autonomous trucks the canary-in-the-coal-mine for other mining jobs? While there is a concern that autonomous trucks will replace jobs in Australia’s mining industry, the good news […]

Brighsun’s Li-S Batteries to enter industrial trials

Lithium Sulfur (Li-S) Battery Technology Breakthrough Through nearly 8 years of research, the Australian company Brighsun’s team, developed lithium-sulfur (Li-S) batteries with an energy density 5-8 times higher than conventional secondary batteries. According to results from an internationally accredited testing agency (SGS), Brighsun’s new technology allows an Li-S battery to keep 91% of its initial capacity after 1,700 cycles at a rate of 2C (being fully charged/discharged in 30 mins). That means the capacity decay per cycle is as low as 0.01%. Even at a more aggressive rate of 5C (being fully charged/discharged in 12.5 mins), Brighsun’s Li-S battery retains 74% of its initial capacity after 1,000 cycles (capacity decay per cycle of 0.026%). The cathode energy density for the 1th cycle after activation at charge rate of 1C is 2103.8Wh/kg. Driven by the growing markets world-wide for EVs, the battery industry has explored a range of chemical combinations: lithium iron phosphate, lithium cobalt oxide and, currently, nickel manganese cobalt. However, current battery systems still suffer from the major disadvantages of relatively low energy density, high raw material costs and secondary pollution during recycling. A Game Changer Brighsun’s advanced Li-S chemistry, offering high energy density and resultant low raw material costs, will be a game changer in the EV industry. Li-S batteries also have the potential to become the most promising energy storage systems for future railways, ships and airlines. Industries such as electric supply grid storage, mobile phones, drones and AI will also benefit from dramatically higher energy density storage provided by Brighsun’s new battery system. Companies in the US, Germany, Korea and China have been developing Li-S batteries and have achieved promising breakthroughs. However, these systems still face a number of challenges, including volume expansion of cathode materials during cycling, the shuttling effect of polysulfides, and the dendritic […]

Australia’s natural sanitiser: Lemon Myrtle in demand

A lemon myrtle farm in Far North Queensland has retooled its entire operation to meet the growing demand for hand sanitiser and cleaning products in the wake of coronavirus. Lemon myrtle has natural antibacterial, antifungal and antimicrobial properties. To keep up with a spike in customer enquiries, Australia’s largest producer, Australian Native Products, has shifted its entire Mareeba production from turning 95% of its harvested lemon myrtle into dried leaves to distilling 100% of the crop into lemon myrtle essential oil. Lemon myrtle essential oil can then be used as a natural antibacterial in hand sanitiser and cleaning products. The farm expects to produce more than 300kg of lemon myrtle oil between now and June. CEO James Gosper can discuss the installation of the new still and how the farm has reworked its entire crop away from drying to distilling. As a whole, the company is working to make use of the bi-products of lemon myrtle. They have developed manufacturing processes to extract hydrosol from the plant which can be used in fragrances, as well as microfibre which they hope to market into body scrubs and cosmetics.

The case of the missing microns

With 85% of Australia’s population living within 50km of the coast, sand and fine grit are ever-present problems in municipal and industrial water and wastewater systems. At the Ozwater’20 exhibition Stand N04 (to run from 5-7th May in Adelaide), local wastewater and screening authority CST Wastewater Solutions will be showcasing the latest advances in fine screening, grit removal and clarifier technologies, including globally proven Smith & Loveless technologies, for which it is Australian distributor. According to Smith & Loveless, as much as 40-80% of the grit contained in municipal wastewater is in the 105-200 micron size range, but most grit removal systems are designed to remove grit in the 200-300 micron range. “This discrepancy has meant that grit removal systems have been stuck in the 20th Century, but Smith & Loveless has new, superior technology to advance grit removal and improve local wastewater systems,” says Mr Michael Bambridge, Managing Director of CST Wastewater Solutions. Bringing grit removal into the 21st Century Smith & Loveless’ latest PISTA® VIO™ system removes 95% of grit down to 105 microns, and features full variability of the inlet and outlet channels. This technology – which CST will be displaying at Ozwater’20 – features a hydraulic vortex grit chamber design that utilises a new baffle system. This type of grit removal system – one of the first of its kind in the industry – provides the ability to design the inlet and outlet channels at any variable angle up to the full 360° of the chamber. Designers can arrange the system to fit existing sites, or maximise space during construction on new sites. The choice is clear for clarifier technology In addition to grit removal, CST will also be displaying its range of Smith & Loveless clarifier technologies at Ozwate’20, including centre feed clarifiers, peripheral feed […]

Morrison government will use purchasing power to encourage plastics recycling

The Morrison government will use its procurement policy to encourage the recycling of plastics, as well as committing financial assistance for upgrading infrastructure to boost the capacity for this waste to be reused. Scott Morrison will announce the initiatives to a national conference in Canberra today that is looking at the challenge of dealing with this escalating and environmentally destructive problem. The meeting is attended by industry, government and community representatives. The prime minister, who has previously highlighted better management of plastics waste as a priority for his government, will emphasise that for major change “the only way forward is in partnership – working with our neighbours; state, territory and local governments; industry, our manufacturing sector and supermarkets; waste operators, and with consumers and communities”. In a speech circulated ahead of delivery he proposes “three pillars” for tackling the problem: taking responsibility for the waste; encouraging demand for recycled products; and expanding industry capability. Plastics “are choking our oceans. Scientists estimate that in just 30 years’ time the weight of plastics in our oceans will exceed the weight of fish in our oceans. That’s appalling. “Taking responsibility means recognising the problems we are contributing to – and it also means keeping faith with the Australian people who recycle,” Morrison says. “Only 12% of plastic put out in the yellow bin for recycling is actually recycled. Australians don’t expect their waste to be exported to someone’s village or waterway.” Morrison will meet state and territory leaders at the Council of Australian Governments (COAG) next month to finalise a ban on the export of waste plastic, paper, glass and tyres. He stresses this isn’t to ban the export of value-added recyclable materials. Morrison says more investment is much needed in the recycling industry; this and collection systems are under “severe strain”. Investment […]

Oomiak Refrigeration opens office in Kuala Lumpur

The Melbourne Markets Epping plantroom is concepted, designed, installed and maintained by Oomiak Refrigeration. The company started in 2006 in Adelaide, South Australia, and has established a presence in every mainland Australian state with its expertise in the design and manufacture of industrial and commercial refrigeration. Oomiak already has several clients in Asia including in Sri Lanka, South Korea, Philippines and major Malaysian frozen food manufacturer Kawan. Co-founder and Chief Executive Officer Cate McGuire said establishing a permanent presence in Asia had always been part of Oomiak’s growth plan. She said the new Kuala Lumpur office had already attracted interest from the Malaysian government, which has recognised the need for sustainability in fresh produce. “The Asian market has a rapidly growing appetite for fresh fruit and vegetables, and with that comes the need to adequately cool and store produce to ensure it maintains maximum freshness for customers,” McGuire said. “Our leading-edge industrial refrigeration equipment and fresh produce ripening systems, as well as the expert advice we give to clients, has been extremely well received in Asia. Oomiak was engaged by Perth Shipbuilder Austal to supply and commission air conditioning systems for two Cape Class Patrol Boats for the Royal Australian Navy. “We see enormous growth in the region over the next decade and we feel we’ve really got something to offer in terms of reducing wastage, preserving the shelf-life of food and adding value for them.” The use of natural refrigerants such as ammonia and its engineering capacity to design efficient systems tailored to specific client needs has been key to Oomiak’s success. Oomiak has about 65 employees with about 25 of those based at its Adelaide headquarters

Commercial pilot projects fast track green cooling technology

Industrial cooling systems that utilise solar energy, thermal storage, smart technology and non-toxic refrigerants will be trialled at three major commercial sites. South Australian company Glaciem Cooling Technology has received $2 million in Australian government funding through the Australian Renewable Energy Agency (ARENA) to demonstrate the technical and economic value of integrating thermal energy storage with renewable energy into Heating, Ventilation, Air Conditioning and Refrigeration (HVAC&R) applications. The trial systems will be installed in South Australia at Pernod Ricard’s Rowland Flat winery in the Barossa Valley and Ceravolo Orchards in the Adelaide Hills, as well as in the Reef HQ Aquarium in Townsville, Queensland. The $4.95 million project will allow Glaciem to field test its Thermal Energy Storage solution in commercial and industrial HVAC&R settings. Glaciem and the University of South Australia have spent a decade developing a low cost thermal energy storage technology to store and discharge energy using a heat transfer process. This occurs at a temperature suited to the specific application using special material. The technology has the added benefit of using natural refrigerants rather than commonly used synthetic refrigerants, such as carbon dioxide, which are harmful to the environment. The air-cooled CO2 refrigeration system has been operating at The Bend Motorsport Park, about 100km southeast of the South Australian capital Adelaide, for about 15 months, providing UniSA and Glaciem with more than a year’s worth of clean data in a commercial setting. Glaciem’s technology also uses an advanced control and forecasting system to optimise the system’s operation based on weather forecasts, electricity price forecasts, and customer demand forecasts to allow the storage system to maximise savings. Glaciem CEO Julian Hudson said the three projects all demonstrated different applications across a variety of industries and would provide valuable data to prove the financial model in the field and drive the cost of […]

Enough ambition (and hydrogen) could get Australia to 200% renewable energy

Scott HamiltonStrategic Advisory Panel Member, Australian-German Energy Transition Hub, University of Melbourne Changlong WangResearcher, The Energy Transition Hub, University of Melbourne Falko UeckerdtPotsdam Institute for Climate Impact Research Roger DargavilleSenior lecturer, Monash University The possibilities presented by hydrogen are the subject of excited discussion across the world – and across Australia’s political divide, notoriously at war over energy policy. On Friday Australia’s chief scientist Alan Finkel will present a national strategy on hydrogen to state, territory and federal energy ministers. Finkel is expected to outline a plan that prioritises hydrogen exports as a profitable way to reduce emissions. It is to be hoped the strategy is aggressive, rather than timid. Ambition is key in lowering the cost of energy. Australia would do better aiming for 200% renewable energy or more. It’s likely the national strategy will feature demonstration projects to test the feasibility of new technology, reduce costs, and find ways to share the risk of infrastructure investment between government and industry. There are still a number of barriers. Existing gas pipelines could be used to transport hydrogen to end-users but current laws are prohibitive, mechanisms like “certificates of origin” are required, and there are still key technology issues, particularly the cost of electrolysis. These issues raise questions of what a major hydrogen economy really looks like. It may prompt suspicions this is just the a latest energy pipe dream. But our research at the Australian-German Energy Transition Hub argues that an ambitious approach is better than a cautious one. Aggressively pursing hydrogen exports will reduce costs of domestic energy supply and provide a basis for new export industries, such as greens steel, in a carbon-constrained world. Optimal systems cost less We used optimisation modelling to examine how a major hydrogen industry might roll out in Australia. We wanted to identify where major plants […]
