Aussie invention could save old coal stations by running them on zero-emissions ‘Lego’ blocks – The Conversation Australia
The blocks can be used to run steam turbines at power stations as a clean alternative to burning coal, and at a fraction of the price of storing energy in batteries.
As climate change worsens, the future of fossil fuel jobs and infrastructure is uncertain. But a new energy storage technology invented in Australia could enable coal-fired power stations to run entirely emissions-free.
The novel material, called miscibility gap alloy (MGA), stores energy in the form of heat. MGA is housed in small blocks of blended metals, which receive energy generated by renewables such as solar and wind.
The energy can then be used as an alternative to coal to run steam tu…
