Energy cost of heat activating serpentinites for CO2 storage by mineralisation

- Practical cost estimates for New South Wales serpentinites is A$ 1.25 per tonne of available active serpentine.
- Serpentinite heat activation requires an energy input of at least 541 MJ (tSerpentinite)−1.
- Practical strategy incurs CO2 penalty of ∼7%.
