South Australian CCT Energy Storage firm produces the world-first TED thermal battery

CCT Energy Storage's TED (Thermal Energy Device) battery aims to revolutionise renewable energy.

South Australia’s CCT Energy Storage launched the world’s first working thermal battery in 2019. The TED (Thermal Energy Device), battery accepts any form of electrical input to convert and store energy as latent heat. This makes it versatile, affordable and long-lasting.

TED can be scaled to power remote communities, businesses, micro grids, rail signalling or telecommunication, as a substitute for diesel generation.

CCT Energy Storage originated in 2011 in small factory in the southern Adelaide suburb of Lonsdae when a tenacious group of scientists and engineers began researching, developing and designing a large-scale thermal battery to revolutionise the market for global renewable energy.

The cutting-edge technology and its potential grew exponentially which led to Climate Change Technologies Pty Ltd being formed as a private South Australian company in 2011 and a working scale prototype in 2012 from more than $6 million in research and development.

In 2019, the company's Lonsdale plant was set to make 10 units for commercial customers that year and production expected to rise to 200 by 2020.

CCT Energy Storage’s thermal battery incorporates a unique phase change material that can store energy at more than 12 times the energy density of a lead acid battery. The stored energy can then be extracted from the thermal battery via a heat engine, to provide an electricity supply when needed.

The thermal battery is not only suitable for renewable energy such as wind and solar. It’s also adaptable to non-renewable energy sources from fossil fuels. Climate Change Technologies has found a Swedish partner in MIBA Solutions for manufacturing and distributing TED throughout Europe.

Adelaide backs William Bragg's first use of X rays probing atomic structure in crystals

The 1915 Nobel Prize for physics, shared by William Bragg and son Lawrence, had its first steps in Adelaide.The Braggs won the prize for “the analysis of crystal structure by means of X-rays”.  In 1896, Bragg showed Adelaide doctors the use of X-rays with equipment supplied locally. Philanthropist Robert Barr Smith financed radium bromide for Bragg to continue experiments. Bragg later wrote “On the ionisation curves of radium” with Adelaide University student Richard Kleeman.

SA Power Networks takes over ETSA's distribution; retailers manage the accounts

SA Power Networks (formerly ETSA Utilities), 51% owned by Hong Kong-based Cheung Kong Infrastructure part of the group of companies headed by Hong Kong-based La Ka-Shing's group of companies. The other 49% is owned by ASX-listed investment company Spark Infrastructure. SA Power Networks operates the former ETSA distribution network in mainly built-up areas of South Australia. It has thousands of kilometres of power lines and hundreds of substations within these built-up areas. SA Power Networks delivers electricity from the high-voltage network (run separately by ElectraNet) through poles and wires in built-up areas to properties or businesses; installs, maintains and reads meters; provides emergency responses to blackouts in built-up areas; and repairs street lighting. SA Power Networks also provides electrical infrastructure management, construction and maintenance for other businesses and government. Retailers, such as AGL and Origin, manage electricity consumers’ accounts, including billing and service enquiries. They organise connections and disconnections. In 2018, the federal court dismissed an appeal by SA Power Networks to charge more for distribution, meaning it will be able to raise $700 million less than sought up to 2020. The state government is responsible for off-grid power supply to remote communities.


Adelaide Oval's first sports event under lights in 1885: Adelaide v. South Adelaide footy

The first sports event under lights at Adelaide Oval was an Australian football match between Adelaide and South Adelaide on July 1, 1885, from 8pm. Adelaide engineering company F. Howard Clark and Co. supplied the six electric arc lamps, with two steam-powered dynamos for each three. Four lamps were 1,000 candlepower, made by Anglo-American company Brush, and two of 2,000 candlepower by the German industrial giant Siemens. The lamps were mounted on 30-feet poles equally spaced around the oval just outside the boundary flags. The game was well attended but the lighting didn’t allow a full view of the game, especially when the ball’s white paint wore off. There also were brief lamp failures. Adelaide won the game 1 goal 8 behinds to 8 behinds. Francis Howard Clark was manager of the engineering side of the company behind the Adelaide Oval venture. Clark, who founded an engineering shop in Port Adelaide, built windmills and pumps of his own design. His windmill was shown at the 1879 Adelaide Industrial Exhibition; his pumps were well received at the Adelaide Exhibition in 1881. A portable steam engine and well-boring equipment won prizes at the Royal Adelaide Show in 1887.

$1.8m Brabham BT62 supercars being built at Edinburgh Parks near former Holden's factory

The Brabham BT62, one of the world's most exclusive cars, has been designed in Adelaide and built in an Edinburgh Parks factory near the former General Motors-Holden’s site at Elizabeth, north of Adelaide, from 2018. Seventy of the vehicles, each priced at $1.8 million, are being made by the Fusion group and Brabham Automotive, named after Australian Formula One world champion Jack Brabham. The company's director is David, youngest of his sons. The BT 62 has carbon-fibre bodywork and is powered by a 5.4 litre V8 engine producing 522 kW. The 7.77-kilometre track at The Bend Motorsport Park in Tailem Bend is testing place for the car. The build will be limited to 70 cars to mark the years since Jack Brabham launched his racing career. The company chose South Australia due to its “rich automotive heritage” and Adelaide a “a centre of excellence for engineering capability and capacity”. The Australian Grand Prix was last in Adelaide in 1995, the year after Jack Brabham's son David raced his final season in Formula One with the Simtek team. Jack Brabham became a legend for winning the Formula One championship in his own car. The BT62’s livery was designed to celebrate Sir Jack's 1966 French Grand Prix victory at Reims in his BT19, which he made on a design by partner Ron Tauranac.  Jack Brabham died in 2014 – the year David Braham won a seven-year battle to retrieve the Brabham name from a German organisation. David Brabham was introduced to the Fusion group in Adelaide and was impressed by their advanced manufacturing capabilities and vision. for the BT62 project. 

Institute of Machine Learning at Adelaide University a computer vision world leader

The Australian Institute for Machine Learning, one of six research institutes at the University of Adelaide, is a world leader in computer vision. With more than 100 researchers, it’s the largest Australian university-based research group in machine learning. Its work follows four themes: theory of machine learning (artificial intelligence that enables computers and machines to autonomously learn how to do complex tasks without being overtly programmed), trusted autonomous systems (able to make explainable decisions, intelligently controlling autonomous vehicles, asking questions when uncertain about decisions and applying reasoning to their surrounds), robotic vision (giving machines the ability to “see” and understand the physical world, using camera hardware and computer algorithms) and visual question answering (enabling computers to give natural-language answers to natural- language questions about the content of visual images.) The Australian Institute for Machine Learning (AIML) was officially established in 2018 with investment from the state government and the university. But the institute was formed from the university’s Australian Centre for Visual Technologies, with a long history of high-impact fundamental and applied research. Its success and experience formed the core of AIML. Machine learning has potential to deliver major social, economic and environmental benefits and impact areas including health, education and finance. Adelaide University AIML’s strengths lie in artificial intelligence, computer vision and deep learning that support machine learning.
