Clean energy technologies

At the core of the Swanbank Clean Energy Hub will be development of new clean energy technologies to replace the coal-fired power stations of the past. In September 2023, CleanCo conducted an Expression of Interest (EOI) with the energy sector, to help us understand the suitability of various technologies. This EOI process will enable CleanCo to make decisions on the final mix of future energy options suited to the site. Recommendations about the energy mix at Swanbank will be made to the CleanCo Board in December 2023. Explore the tabs below to find out more about clean energy technologies being considered for Swanbank.

Did you know? Queensland has the highest uptake of rooftop solar in Australia. However, efficiency of grid-scale solar PV systems reduces as you get closer to the coast due to increased cloud cover.

Did you know? Lithium-ion batteries have a high energy density which makes them suitable for short duration grid-scale energy storage.

The technology uses chemicals to absorb and release energy on demand. Installing batteries with renewable energy generation allows that energy to be stored during times of low demand and dispatched at times of peak demand.

Batteries are particularly valuable because they provide flexibility to the electricity network. They can respond faster than other energy storage or generation technologies and help maintain grid stability by turning on and off in fractions of a second.

A 250MW battery is proposed for the Swanbank Clean Energy Hub.

*Neoen is one of CleanCo’s strategic partners, developing the Western Downs Green Power Hub and the Kaban Green Power Hub.

Did you know? Flow battery technology dates back to the 1880s and was demonstrated as a power source for electric cars in the 1970s.

The term ‘flow battery’ describes a form of medium duration energy storage that has potential to compliment pumped hydro or conventional lithium-ion batteries for grid-scale energy storage applications.

The main difference between flow batteries and other rechargeable battery types is that the active materials are stored in exterior tanks and pumped toward a flow cell membrane and power stack.

Did you know? The Swanbank combined cycle gas turbine is one of the most efficient, low-emission, flexible gas-fired power stations in the world.

By using highly efficient combined-cycle technology, waste heat from the gas turbine is used to generate additional electricity via the steam turbine at no extra fuel cost.

As Queensland grows its renewable generation and storage asset fleet to meet renewable energy targets, gas will continue to play an enabling role, to ensure Queenslanders have a sustainable, reliable and affordable clean energy supply even when there is no wind or sun.

Did you know? Hydrogen is the most common chemical in the universe and the first hydrogen fuel cell car was produced in 1966 by General Motors.

Hydrogen can be produced as a gas or liquid, or made part of other materials. It can have many uses such as fuel for transport or heating, a way to store electricity, or a raw material in industrial processes.

When hydrogen is produced using renewable energy or processes, it becomes a way of storing renewable energy for use at a later time when it is needed.

Did you know? Some thermal energy storage systems can store excess thermal energy for months, potentially providing energy when wind and solar technologies are not generating.

Thermal energy storage refers to the application of heating (or cooling) a medium for later use of the energy.
