Schneider Electric (SE) has been awarded the Energy & Sustainability 2022 Microsoft Partner of the Year Award for its EcoStruxure platform. These awards are given out to Microsoft partners that have used Microsoft-based applications, services or devices in particularly successful and innovative ways.

SE’s EcoStruxure platform is a software suite that helps users keep track of their systems and analyse their energy usage and expenditure. The company claims the software has helped its customers reduce their carbon emissions by 84 million tonnes — a saving of 347 million tonnes since 2018.

Olivier Blum, Executive Vice-President Energy Management at Schneider Electric, said: “Receiving the 2022 Microsoft Energy & Sustainability Partner of the Year Award is a great recognition of the collaborative impact we are making together, to tackle climate change.

“We are at a critical juncture. Unless immediate action is taken to reduce emissions, we will shortly pass the point of no return. Companies are central to avoiding this; however, alone the impact will not be enough. That is why collaborations such as the one between Schneider and Microsoft are needed to supercharge innovation efforts and create the technology which can turn the tide.”

Nick Parker, Corporate Vice President of Global Partner Solutions at Microsoft, said: “I am honoured to announce Schneider Electric as the 2022 Microsoft Energy & Sustainability Partner. Schneider Electric were outstanding among the exceptional pool of nominees.

The Australian Renewable Energy Agency (ARENA) has announced that it has invited 12 projects to submit applications to the Large Scale Battery Storage (LSBS) Funding Round.

The LSBS is a funding scheme that is part of the Advanced Renewables Program, and will see $100m doled out to selected projects that are able to store energy and release it back into the grid using advanced inverted technology.

The 12 shortlisted grid-scale batteries have an aggregate capacity of 3050 MW/7000 MWh and a total ARENA grant request of $297m.

ARENA Acting CEO Chris Faris said the expressions of interest submitted for the funding had exceeded ARENA’s expectations.

“We are really encouraged by the number and quality of applications to the round; it’s shaping up to be very competitive. The 12 shortlisted projects represented the strongest of an impressive field and we’re looking forward to seeing their full applications.”

The LSBS scheme is being developed on the back of the identification of the importance of advanced inverters for the country’s swap to renewable energy, with the Australian Energy Market Operator publishing studies in 2021 and 2022 that looked at its use in an energy market with predicted increased power requirements.

“Advanced inverters that can help stabilise the grid are the missing piece of the puzzle that will support the transition to 100% renewable energy penetration for short periods,” Faris said.

Unsurprisingly, with such a large amount of money on the table, the scheme has been quite stringent with its eligibility requirements and expectations, with the most salient one here being that the funded project must be able to store 70 MW of energy at a minimum.

Shortlisted applicants will now be required to submit their full applications by 20 July 2022, and the winning applicants are expected to be announced in late 2022.

There is a sense of urgency to achieve hydrogen production at scale because it is considered an important part of most pathways to achieving global net zero emissions. The International Energy Agency has forecast we will require more than >500 Mta of hydrogen production globally by 2050 to achieve emissions targets. This is equivalent to more than three times the current global LNG industry and a daunting task in such a short period of time.

This is compounded by the crisis in Ukraine, which is changing the economics of hydrogen and making it increasingly important as an alternative fuel. In this future energy economy, Europe, South Korea and Japan are shaping up to become net hydrogen importers while the Americas, the Middle East, Africa and Australia are in a strong position to become hydrogen exporters.

Hydrogen hubs have emerged as arrangements and mechanisms to drive the viability of producing hydrogen at scale.

Following a significant amount of work to set the right policy and funding conditions, the concepts of hydrogen clusters, hydrogen hubs and even hydrogen valleys have materialised quickly in Australia — despite the pandemic.

It is now accepted that hydrogen hubs will be the catalyst that will unlock wider economic benefits of hydrogen activities in an identified region. Hydrogen hubs concentrate activity locally and enable infrastructure to be shared, scale to be increased and costs to be reduced. They also help coordinate and maximise engagement of local communities. They have the potential to facilitate industry investment and drive regional growth, allowing us to scale up faster.

Australia is not alone, with the US Government seeking to develop at least four hydrogen hubs. In Australia, hydrogen technology clusters exist in every state and territory.

Through our involvement in several hubs across Australia, including Port Bonython in South Australia, Bell Bay in Tasmania and the Middle Arm Sustainable Precinct in the Northern Territory, we have identified several common elements that will help accelerate the development of hydrogen hubs:

Industrial ecologies: This concept is based on the notion of enabling an existing industrial precinct to transition to a future community utilising future energy and has the potential to de-risk developments. It consists of three elements:

1. Blending or changing the energy feedstock; for example, shifting from gas power to blended or converting energy-intensive processes to use green hydrogen.
2. Reskilling human capital to adapt to the changes necessary to utilise the change in technology and feedstock.
3. Creating local markets for the green products manufactured; for example, transport refuelling, green ammonia as a fertiliser or green steel for construction. This ecology can then grow and develop into an export hub as production increases.

Investor capital: While public sector approvals and investment are critical, hydrogen hubs will be capital-intensive and require significant investment from the private sector. It is important to bring private investors on the journey and get their buy-in early. Overlaying commercial models to inform decision-making and investment pathways has proved highly beneficial. For example, the modelling we have undertaken for projects such as the Geraldton Export Scale Renewable Investment Project tells us that scale is critical for export markets. Emerging thinking regarding the potential of local hydrogen ecosystems is worth exploring; however, most investment decisions will rely on a scalable proposition for viability.

Stakeholder engagement: While there is widespread acknowledgement and even support for hydrogen as a critical clean-burning energy source, large-scale infrastructure required for hydrogen hubs has broad implications for both the environment and the community. Our recent experience has shown that a facilitated, collaborative approach can be valuable in extracting stakeholder perspectives upfront and unlocking insights early.

Clear and efficient approval pathways: As we charter new territory, having defined approval pathways in place will facilitate the expediency with which these projects can evolve. The planning phase should not be underestimated in its ability to determine success.

Although bankability is not there yet, we need to capitalise on the progress and momentum generated. Creating reliable technology and productivity of electrolysers to meet their anticipated performance will help build confidence in long-term demand.

Australia has all the key attributes to be a major producer of clean energy servicing both the domestic and international market, particularly those countries with less natural advantage. We have ample space, energy sources such as sun and wind, extensive coast lines, low population density and high technology know-how. As a collective we can unlock more of the industry potential faster and set a benchmark for the global stage.

Researchers from Sweden’s Chalmers University of Technology have developed a circular economy technique that sees mixed waste converted into raw carbon atoms to be used in the production of plastic.

Mixed waste usually ends up in landfills or being incinerated. The Swedish scientists were looking to develop a technology that could utilise molecules in plastic, paper, wood and food waste, all of which are full of useful carbon atoms that otherwise go unused.

“There are enough carbon atoms in waste to meet the needs of all global plastic production. Using these atoms, we can decouple new plastic products from the supply of virgin fossil raw materials,” said Henrik Thunman, Professor of Energy Technology at Chalmers and one of the authors of the new study.

“If the process is powered by renewable energy, we also get plastic products with more than 95% lower climate impact than those produced today, which effectively means negative emissions for the entire system.”

Plastic recycling is generally inefficient and only reclaims a relatively small amount of material for further use. The advanced recycling method proposed by the researchers uses thermochemical technologies and sees waste being heated to 600–800°C to convert it to gas, after which hydrogen is added to subsequently produce plastic.

“The key to more extensive recycling is to look at residual waste in a whole new way: as a raw material full of useful carbon atoms. The waste then acquires value, and you can create economic structures to collect and use the material as a raw material worldwide,” said Thunman.

The researchers were inspired by the natural carbon cycle, whereby plants absorb CO₂ for nutrients and then release it back into the atmosphere when they die, where it is used again to grow more plants in the future.

“However, our technology differs from the way it works in nature because we don’t have to take the detour via the atmosphere to circulate the carbon in the form of carbon dioxide. All the carbon atoms we need for our plastic production can be found in our waste, and can be recycled using heat and electricity,” said Thunman.

The researchers suggest that renewable energy can be used to power this advanced recycling process, which would be more energy efficient that currently used methods for disposing of mixed waste. Unused heat from the process could be harvested for use elsewhere too.

The research was carried out as part of the FUTNERC project, which is helping the chemical industry reduce greenhouse gas emissions. The processes have been tested through collaboration with a plastic manufacturer, Borealis.

“Our goal is to create a circular economy for plastics,” said Anders Fröberg, CEO of Borealis. “Our plastic products are key to the transformation to a sustainable society, so it’s important for us to support research like this. We already have projects that create circularity for our plastic products, but more solutions are needed. Therefore, we are pleased with these excellent results, which can help bring us a step closer to our goal.”

The study describing the technique was published in the Journal of Cleaner Production.

Kaeser recently expanded its FBS series of rotary screw blowers with the inclusion of the FBS 720 models. The oil-free compression blower technology is designed especially for water industry applications.

With a flow rate of 18 to 72 m³/min and pressure differentials from 0.3 to 1.1 bar, as well as a selection of motors ranging from 45 to 110 kW, the series has good energy efficiency, space-saving design and automation.

The SFC version is equipped with a frequency converter and a synchronous reluctance motor — a slip-free design that combines all the advantages of high-efficiency permanent-magnet motors with those of robust, service-friendly asynchronous motors. Thanks to variable speed control, the flow rate can be adjusted as required and a control range of 1:4 is achieved, allowing good dynamic operation.

The STC version is now equipped with an energy-saving IE4 Super Premium Efficiency motor, which reduces energy consumption and therefore costs.

On both versions, power transmission from the motor to the airend takes place via loss-free and maintenance-free gearing, which results in an improvement of up to 7% in specific package input power as compared to the previous model.

Furthermore, efficiency remains constant across the entire control range and flow rate is virtually unaffected by pressure fluctuations. This allows the blowers to be regulated and adjusted at all times via the master control system.

Despite the compact dimensions, Kaeser has dispensed with the requirement for maintenance access from one side, thereby permitting side-by-side installation. This results in space savings, particularly when operating multiple blower systems.

The units are delivered ready for immediate connection, including controller and frequency converter or star-delta starter. All units are CE and EMC-certified, thereby minimising the planning, construction, certification, documentation and commissioning costs for planners, operators and plant manufacturers.

The FBS series models are available to order from September 2022.

Macquarie Data Centres has announced a partnership with ResetData, which will be providing Submer data centre cooling technology that will help reduce energy use.

The technology from Submer uses immersion cooling for servers and data centres and the company claims that it can reduce CO₂ emissions by up to 45%, while reducing the physical cooling footprint by up to 90%. The heat produced by the hardware can be recycled and the cooling process does not produce wastewater. ResetData is also providing disaster recovery-as-a-service (DRaaS) for Macquarie Data Centre’s sovereign facilities.

ResetData Co-Founder and Managing Director Bass Salah said the technology enabled efficient GPU-as-a-service (GPUaaS), which could offer advantages for 3D rendering, architectural design services, institutional blockchain and possibly even the development of virtual worlds.

“As an example, the New South Wales Government is building a digital twin of the entire state,” Salah said. “It will replicate all levels of infrastructure, street scale and built environment in a single pane, which requires significant processing power once this becomes completely populated. It’s vital that governments are leveraging the most efficient data centre technologies.

“It’s in projects like these, and the investments hyperscalers are making, where we see the beginnings of the metaverse — a virtual world with which people engage through digital avatars — take shape. Very few people and companies are thinking about the underlying infrastructure needed to power this new virtual world, including data centres which are the heart of it, and without these considerations, the real world will suffer.”

Macquarie Data Centres Group Executive David Hirst said the partnership will expand the service offering by the company.

“Our partnership with ResetData enables increasingly important technologies such as GPUaaS to drive Australia’s digital economy. It’s good to see how technologies come to market which enable the digital applications of the future.”

The Victorian Government has announced a $10 million grants program that will support projects that create electricity, heat, gas or liquid fuel from organic waste that would otherwise go to landfill. Applicable waste content includes agricultural, livestock, food and wood waste.

The $10 million Waste to Energy: Bioenergy Fund is aiming to help industries from the farming or food production sector convert organic waste into renewable energy. Projects that create jobs, create economic opportunities and foster energy independence through the safe conversion of waste into energy will be prioritised.

“Bioenergy will play a major role in delivering our targets to halve organic waste sent to landfill by 2030 and will help us on our journey to net zero by 2050,” said Minister for Environment and Climate Action Lily D’Ambrosio.

“We’re creating regional jobs and new industries and income streams for farmers through our investment in bioenergy, while diverting organic waste from landfill.”

The projects under the fund are expected to deliver around 5000 kW in renewable energy production.

The fund is taking applicants under two streams: the first concerns project development and will help applicants make progress towards new technologies, whereas the second will support projects that have already been proven but need help with constructing or purchasing infrastructure. Each stream has its own eligibility requirements and funding limits.

Funding can be applied for until 16 August 2022.

In 2003, a meeting of the United Nations Environment Programme Finance Initiative created the concept of ‘ESG’, or ‘environmental, social and corporate governance’. For a long time it remained something of a buzz phrase, understood by few and cared about by even fewer, but in recent years ESG has morphed into a global phenomenon with ESG assets tipped to surpass US$41 trillion in 2022 and US$50 trillion by 2025 — one-third of the projected total assets under management globally.

The rise in profile for ESG in the investor world has undoubtedly coincided with a rise in momentum behind social causes worldwide as growth in natural disasters has fuelled the climate movement, and of course, corporations and funds have been quick to jump on the ESG bandwagon. But perception and reality of a company’s credentials can vary widely, and after years of media reports and widespread concern around ‘greenwashing’, the ASX recently announced a crackdown on ethical funds, joining ASIC to fight against those using the market disclosure system to fake green credentials.

That’s exactly what greenwashing is. What we see is certain companies pretending or promoting that they are doing the right things by ESG, but not really putting the right fundamentals in place. It’s important to note that there are myriad reasons why this practice has grown globally, not least of which is the fact that ESG doesn’t have a global standard. It can be interpreted in a variety of ways, and the result is a variable outcome for companies, investors and, of course, the environment.

Tesla, the ‘clean energy electric car’ company, recently released its 2022 Impact Report, in which the company dismissed the way ESG assessments measure sustainability and the relationship between businesses and the environment. Elon Musk used the report to commit to measuring “real world impact” instead, and called for the baseline approach of ESG to be updated beyond measuring whether an environmental issue impacts the profitability of a company.

A short time later, Tesla was kicked out of the S&P 500 ESG Index. At the same time, ExxonMobil is rated top 10 best in the world for environment, social and governance by the S&P 500. Musk has since called ESG a scam, saying it’s been weaponised by phoney social justice warriors.

But let’s take a step back and look at why people want ESG credentials to begin with. If you look at the results of the Australian Federal Election, the success of the Teal Independents running in traditionally safe Liberal seats on a platform of climate action, it’s pretty clear to see that people want to see change. Punters want to be contributing to a proactive stance on climate change and making a positive impact on the environment. As a result, an increasing number of funds want to be investing into companies that are seen to be doing the right thing.

In Australia we’ve seen quite a few companies come up and flout their ESG credentials without too much substance behind it. Up until now, there’s been very few that are really driving the change, but there’s definitely a shift happening. A younger generation wants to see change, and they are voting with their feet. So funds will have to start to provide a level of transparency and consistency around the companies they are investing in and what they are doing. We have seen recently ASX-listed mining company IGO release an entire ESG deck, including presentation materials for an upcoming ESG Roadshow. This could be seen as a watershed moment, particularly if they deliver on their promises.

The question remains around how we move towards a place where we have globally recognised ESG standards. At Envirosuite, our view is that before we get to that point, companies need to have a monitoring baseline so that investors and funds can understand and collect data around their operations, and be willing to share that in somewhat of a transparent way. We have certain customers around the world that proactively want to monitor their environmental impact, and make that available to the rest of their industry, as well as to their local communities and to government, and they are growing in number.

We believe in the importance of environmental intelligence to form this baseline. So, for example, our software platform will collect various environmental parameters like noise and vibration, air quality, water quality, dust impacts, etc. We will bring that into our platform and provide real-time monitoring for our customers, and that will then generate reports that our customers can then directly put into their ESG compliance statements. Furthermore, we’re actually helping a lot of customers around the world from airports, mining industrial facilities and waste facilities to actually provide compliance to regulatory bodies to make sure that they are not exceeding any of those parameters.

Adoption of baseline standards needs to grow, and the more people that come into this segment, the faster the industry will accelerate. Importantly, too, it’s not just about the monitoring. It’s actually now what you do with that data to drive change. It’s about getting insights from that data, and driving change, whether that’s a government body or private industry, to really drive an improvement in those ESG ratings.

If you are serious about ESG, it’s hard to argue with Elon Musk’s belief that real-world impact is the most important part. This core idea seems to have been lost as many companies have used ESG as a money-making exercise, but we feel it’s inevitable that eventually there will be global standards. The first step to getting there is to ensure that companies are collecting more and more data, and become more and more transparent. Envirosuite is not only well positioned to help with that, but we also believe that purpose is key to turning ESG into something with a more tangible impact for people and the planet.

With the increased use of solar renewable energy over the last few decades, and a limited lifespan of 30 years for solar panels, the global waste generated from silicon in end-of-life solar panels is projected to hit 8 million tonnes by 2030 and 80 million tonnes by 2050¹.

Solar panels are made up of solar cells, which contain a complex mix of various materials such as aluminium, copper, silver, lead, plastic and silicon. Separating such materials and recycling them each in a unique way is a complex and costly process; therefore, current recycling approaches mainly recover only the glass and metallic support structures from solar panels.

Silicon, which makes up 90% of solar cells, normally ends up in landfills. It is challenging to upcycle silicon as recycled silicon has impurities and defects, which cannot be used to create functional solar cells. This makes it difficult to recycle used silicon into solar cells or other silicon-based technologies.

The joint team turned this limitation into opportunity by developing technology to transform expired solar cells into enhanced thermoelectric material. Compared to solar cells, this technology capitalises on the contrasting properties of thermoelectrics, where the incorporation of impurities and defects serves to enhance rather than diminish their performance.

Scientists from A*STAR’s Institute of Materials Research and Engineering (IMRE) and Institute of High Performance Computing (IHPC), led by Dr Ady Suwardi, Deputy Head of the Soft Materials research department at IMRE, contributed their expertise in material properties and computational modelling, respectively, to determine the optimal composition of materials.

Scientists from NTU’s Singapore-CEA Alliance for Research in Circular Economy (SCARCE), led by Associate Professor Nripan Mathews, leveraged their expertise in extracting valuable materials from solar waste to develop the technologies required for recovery of silicon from solar panel waste.

To impart thermoelectric characteristics such as power conversion and cooling efficiency to waste silicon and to enhance the performance of the upcycled silicon-based thermoelectrics, the team first pulverised solar cells into fine powder using ball milling technology. Next, phosphorus and germanium powder were added to alter their original properties before the powder combination was processed under high heat and temperature using spark plasma sintering.

After evaluating the electrical property of various combinations, the team achieved a sample offering the most optimised thermoelectric performance, with a thermoelectric figure of merit (zT) of 0.45 at 873 K — the highest amongst elemental silicon thermoelectrics.

“This study demonstrates that thermoelectrics is a fertile ground for upcycling defect- and impurity-sensitive semiconductors,” said Suwardi.

“Our goal is to create sustainable materials, extend the life cycle of various products and reduce waste to cultivate a circular economy, and we can only do this through partnership with institutes of higher learning and other collaborators from the local R&D ecosystem,” added IMRE scientist Dr Jing Wu, who was co-corresponding author of the paper together with Suwardi.

This effort highlighted the intertwined research by SCARCE whereby silicon recovered from solar panel waste is being upcycled by A*STAR into silicon-based thermoelectrics for harvesting of electricity from heat. The team will also look to pilot the technology for large-scale upcycling of waste silicon, which can be used for high-temperature energy-harvesting applications such as converting heat generated from industrial waste processes into electricity.

A newly released report from the Australian Energy Market Operator (AEMO) shows that Australia is increasing its transition towards its 2050 net zero targets faster than had previously been expected, with the impacts of coal closures being brought forward, and renewable energy rapidly becoming cheaper.

The ‘AEMO 2022 Integrated System Plan’ also outlines investments in wind and solar capacity, in addition to storage and hydro, for the transition across the next 30 years.

Climate Council senior researcher Tim Baxter welcomed the report and said that the move towards renewables would prove helpful for employment and energy security alike.

“The adoption and transition of renewables will bring immense opportunity to Australians in terms of creating jobs, lowering emissions and ensuring security to our power supply. This transition is essential to protecting Australian lives,” Baxter said.

“Renewables will be doing the major heavy lifting in getting us to net zero emissions, and it’s great to see this report supporting further ramping up of the rollout of wind and solar backed by storage, which is the cheapest form of new generation in the country.

“Off the back of an energy crisis where Australians are being forced to rely on aging and unreliable coal plants and expensive gas, it’s critical we get the transition right and move away from fossil fuels to avoid the worst impacts of climate change.”

Climate Councillor, former President of BP Australasia, former advisor to Margaret Thatcher, and energy expert Greg Bourne said: “AEMO’s latest report reveals that the inevitable transition to renewables is speeding up. It shows wind and solar can provide more of Australia’s energy needs, as we’re seeing fossil fuels becoming more unaffordable and unreliable.

“The scenarios mapped out by AEMO also show that we can push for higher ambitions to transition even sooner than predicted. In a time of energy crisis and also seeing the consequences of a warming atmosphere, Australians want to see renewable power and storage to reduce energy prices, insulate against global energy price shocks and help avoid the worst effects of climate change.”

The ‘2022 Integrated System Plan’ can be found on the AEMO site, in addition to an infographic that demonstrates the 30-year roadmap.
