It seems like it's a MOF amine approach which does have some benefits against the MEA used in submarines, such as lower corrosive properties potentially, lower heating requirements as you don't have to heat an aqueous solution, and it can be easier to discard the remnants once its co2 absorbing properties are diminished.

Sharing this for the community's take on whether it has potential or is just another non-viable option.
