Australia is supplying renewable energy equipment

Australian renewable energy companies are developing technology and supplying equipment. Some projects may fail, but the successes will contribute to Australia’s prosperity and security in a low-carbon world.

The work of these companies shows that Australia has the smarts and will benefit from the energy transition.

Here are some examples.

Electricity export to Singapore: Sun Cable

Australian company Sun Cable is building a submarine transmission line from Darwin to supply Singapore with electricity. This project will use tried and tested technology, but on such a large scale that it could revolutionise world thinking on energy movement.

Concentrating solar & energy storage: RayGen

RayGen is commercialising a fascinating type of concentrating solar and energy storage technology. Mirrors concentrate sunlight to generate electricity and heat. The heat warms a hot-water reservoir while the electricity chills a cold-water reservoir. Then, the temperature difference between the reservoirs powers a heat engine to generate electricity on demand.

Biochar & heat engine: Capricorn Power

Melbourne based Capricorn Power is building its first commercial heat engine. This engine can use various waste heat sources to drive pistons and generate electricity. It fits into a 20-foot shipping container, does not use water or chemicals, and produces no emissions.

Capricorn will combine a heat engine with a biochar-maker. The biochar-maker will supply heat by decomposing clean organic waste in a low-oxygen environment, producing biochar and heat. The heat engine will then use the heat to generate electricity.

Organisations like councils will be interested in using organic wastes like waste food or wood offcuts to:

  • generate electricity and cut power costs.
  • produce biochar to make soils more productive and increase the carbon stored in soils, and
  • avoid organic waste becoming landfill and producing methane as it decomposes.

Robust agriculture: Sundrop Farms

Sundrop Farm South Australia an oasis in an arid landscape

Renewable energy has enabled productive agriculture on this near-desert land, near Port Augusta in South Australia. Sundrop Farms has been growing tomatoes in these greenhouses since 2016. The company supplies Coles and grows about 15% of Australia’s tomatoes. Most Australians would have eaten some.

On the left, there are 20 hectares of greenhouses. They grow tomatoes in water, not in soil. The water is desalinated ocean water stored in the ponds in the foreground. On the right, there are over 23,000 mirrors that focus the sun’s rays on the tower to heat molten salts. The hot molten salts are kept in the storage tanks and used to generate electricity on demand. This generator is a concentrating solar thermal generator. Solar electricity is available 24 hours to power the place, including desalinating seawater.

Sundrop Farms has renewable technology know-how. This successful greenhouse is progress towards the superpower vision.

Electric commercial flight is about to takeoff

People thought that electric passenger planes were only a dream. That’s because batteries are heavy: jet fuel carries more energy per kilogram than batteries, about 100 times more. So, it’s surprising that these battery planes have already flown and could be carrying passengers in 2023.

Energy density: I have taken the energy density of aviation fuel as 45 MJ/kg (Megajoule per kilogram) and the density of Lithium-ion batteries as 0.45 MJ/kg. Note that battery technology is developing rapidly, e.g., researchers have developed a lithium-air battery with four times greater density, 1.8 MJ/kg.

Electric Rubbish Trucks: SEA Electric

Here’s a fully electric rubbish truck that started work in 2019 in the City of Casey, in Melbourne. There is a similar rubbish truck working in Adelaide too. The trucks are designed & made in Australia. Superior-Pak makes the trucks, while SEA Electric supplies the electric drives.

SEA has a factory in Dandenong where they electrify commercial vehicles: trucks, buses, and vans. SEA has won orders in the US – and has moved to Los Angeles, USA.
