Does UCG Syngas Production:
Produce consistent & continuous gas?
Yes - over 18 months continuous operation of UCG Panel 2 at Bloodwood Creek.
No - less than 3 months continuous
operation per reactor.
Have a long duration?
Yes - a single panel will last for over 10 years on air, 5 years on oxygen/steam.
Deliver a consistent gas quality,
critical for downstream processing?
Yes - gas quality is consistent and stable after initial ignition for the entire duration of the UCG panel.
No - to date recorded gas quality decreases constantly over the life of the reactor.
Efficiently convert coal to gas?
Yes - keyseam’s design provides a constant gasification front, offering the highest production efficiency over the life of the UCG panel.
No - as the reactor “vessel” constantly changes size and shape, this reduces the gasification efficiency.
Work without physical intervention
Yes - once built, the keyseam gasifier does not require any physical intervention throughout the life of the panel.
No - traditional designs require repeat drilling or manual retraction of injection points.
Minimise surface subsidence?
Yes - operational depths limit surface subsidence.
Have minimal impact on the environment?
Yes - operating the gasifier below the pressure of the outside groundwater ensures by-products remain within the panel cavity.
Yes - negative water pressure in the reactor ensures gasification products remain within cavity.
