The first commercial pilot of a world-leading molten silicon energy storage system, developed by South Australian innovator 1414 Degrees, was started at SA Water’s Glenelg wastewater treatment plant in 2019.

The 1414 Degrees’ biogas thermal energy storage system (GAS-TESS) stores energy from biogases created by wastewater treatment to increase the plant’s energy self sufficiency.

The project is funded by 1414 Degrees and the South Australian government’s 2017 renewable technology fund, while SA Water will allow the 1414 system to integrate energy storage and heat with its industrial operations.

1414 Degrees, now listed on the Australian securities exchange, expects the use of GAS-TESS in 2019 and give immediate returns for SA Water while building a foundation to apply the technology at similar sites worldwide.

1414 Degrees technology delivers heat as well as electric power. Energy is sourced from renewables or the grid, and is stored as latent heat at constant temperature. The energy is then dispatched on demand. This breakthrough technology is set to disrupt energy storage globally because it provides the world’s most common form of energy: heat.

1414 Degrees’ original technology was developed with a focus on electrical input, such as solar or wind power. In 2017, the company’s engineering team started developing an extra offering – the GAS-TESS – in response to a request from SA Water for technology enabling a biogas input to store energy.

SA Water has been used biogas produced by its wastewater treatment at Glenelg to generate electricity and cover up to 80% of the plant’s needs. The 1414 technology will increase that energy self-sufficiency, support South Australian innovation and lead a global charge to reduce the costs and environmental impacts of energy-intensive wastewater treatment.

1414 Degrees’ listing on the Australian Securities Exchange in September 2018, followed an initial public offering (IPO) that raise more than $16.3 million.

Besides preparing the GAS-TESS at Glenelg, 1414 Degrees has been commissioning its 10MWh TESS-IND and assessing sites for the company’s 200MWh TESS-GRID product line. Across the past two years, 1414 Degrees has raised $30 million in capital privately and through its IPO to support the business’ push into commercial industries.

1414 Degrees is developing joint ventures to commercialise its technology, incorporating generation, thermal storage and industry with heat energy requirements.

The GAS-TESS 10MWh+ is designed to burn biogas and store the energy for recovery as electricity and heat for waste management utilities and entities requiring efficient gas management.

The GAS-TESS idea started in 2009 when Adelaide businessmen Harold Tomblin, John Moss and Robert Shepherd engaged a former CSIRO scientist to develop a device to harness silocon for energy storage. With research funding, mechanical engineer Matthew Johnon developed the technology, and Kevin Moriarty from the mining industry helped commercialise it.

Light and team resign, form own firm, when commissioners want quicker survey method

About 150,000 acres had been surveyed by William Light’s team by June 1838 when George Kingston returned from England to tell that the colonial commissioners’ had rejected therequest for more resources. Light was told to abandon trigonometrical work in favour of running surveys. Light resigned with all but two of his staff. He became principal in Light, Finniss & Co. with Boyle Travers Finniss, Henry Nixon, William Jacob and Robert Thomas, who drew the first map of Adelaide city.


State-wide electronic health records (EPAS) system paused due to rising costs and delays

SA Health’s EPAS (Enterprise Patient Administration System), an electronic health record of patient history, has run into schedule and cost blowouts (from $220 to $500 million) and patient safety concerns. The incoming Liberal government paused the rollout of the system in 2018. EPAS, besides replacing paper records, also aimed to be a single state-wide system unlike in Victoria, NSW and Queensland where individual hospital systems cannot talk to each other.

Miethke's school of the air – and flying doctor – powered by Alfred Traeger's technology

Adelaide Meithke formed and drove the setting up the world’s first school of the air for outback children in 1950. Miethke, a friend of John Flynn, was the (Royal) Flying Doctor Service’s South Australian branch’s first woman president in 1941 and edited Air Doctor. This pedal technology for the radios used by both the flying doctor and the school of the air was developed by another South Australian of German heritage: Alfred Traeger.


Adelaide General Post Office opens in 1872 and receives Australia's first telegraph from overseas

Adelaide General Post Office opened in 1872 and became, on October 22, the place that received the first Morse-code telegraph message to Australia from overseas. This message arrived in Australia via an undersea cable from Indonesia, came ashore at Port Darwin and then down the 3178km line to Adelaide that had been completed in less than two years in 1872. The Adelaide-Darwin line project had been directed by Charles Todd who, as South Australian postmaster general, had major input into the new General Port Office, with its grand postal hall, on the corner of King William and Franklin streets, the colony’s most expensive structure so far at £55,000. Todd specified the shape of the GPO’s Victoria tower with bells, copied from Westminster Abbey, chiming on the quarter hour. The telegraph line from Darwin gave Adelaide the monopoly on  receiving news from overseas for Australia for the next 30 years. News gathering in Adelaide had become highly competitive by the mid 19th Century, with two daily morning titles competing for readers. Before the telegraph line, reporters had been sent to Port Adelaide to travel out with the pilots to board ships newly arrived from London and obtain the latest overseas news. In 1858, the telegraph line completed between Melbourne and Adelaide – via Willunga, Goolwa, Robe and Mount Gambier – enabled Adelaide reporters to send news direct to Melbourne, as well as receive interstate news. An evening newspaper, the Telegraph, was founded to mark this development.

Repower Port Augusta attracts SolarReserve huge solar thermal plant – but lost in 2019

The Repower Port Augusta campaign that attracted a major solar thermal project to the city in 2017 had a disappointing sequel in 2019 when the company behind it withdrew, citing a lack of funding. California-based company SolarReserve had chosen Port Augusta as the site for its Aurora $650 million solar thermal power plant. With the world’s largest single tower, the Aurora plant was to use technology developed by California-based company SolarReserve to store energy in molten salt for eight to 10 hours – an advantage over solar photovoltaic or wind power. Underwriting the project, SolarReserve in 2017 won the contract to supply all the South Australian government’s own energy needs (electrified trains, schools, hospitals) with a solar thermal plant. The project was also given a federal government $110 million concessional equity loan in 2016, in a deal arranged with senator Nick Xenophon. Sited at Carriewerloo Station, the Aurora 150MW plant was to generate 495 gigawatt hours of electricity each year – equivalent to servicing 90,000 homes and around 5% of South Australia’s total needs. The South Australian government was to pay Solar Reserve $75-$78/MWh for power from Aurora. South Australia has no coal-fired power plants since the Northern power station in Port Augusta closed in 2016. After the closure, Repower Port Augusta community group lobbied for the plant to be converted to renewable energy not only for clean energy but also jobs that the project might bring to the town. SolarReserve’s Crescent Dunes in the Nevada desert uses an identical technology. 


Moomba-Adelaide gas pipeline in 1960s; link to the national power grid via Heywood in 1990

The expanding electricity market in all states budged the start of a national gas pipeline network in the late 1960s. This meant building long pipelines, including a 780km natural gas line from Moomba in the Cooper Basin to Adelaide in 1969. Its gas was used at the Torrens Island power station. South Australia became linked in 1990 to New South Wales-Victoria electricity power sharing, via an interconnector at Heywood in Victoria where the Victorian ended its 500kV power line to the Portland smelter. Australia’s power grid links grew into the world’s largest, connecting South Australia with Queensland, New South Wales, Victoria and Tasmania over 5000 kilometres from Port Douglas in Queensland to Port Lincoln in South Australia. From 1998, this national synchronous transmission grid has brought into play the National Electricity Market (NEM), as the trading place for the Australian wholesale electricity market. More than $11 billion of electricity is traded annually in the NEM to service almost 19 million end-use consumers. South Australian both draws from and feeds into this national market of electricity trading. Main points of concern have been whether South Australian should have more than one main link to the national grid and whether the grid is geared to accommodate the entry of renewable energy in a market otherwise dominated by coal-fuelled power in the eastern states.
