CARBON CAPTURE & HYDROGEN STORAGE

I have been doing some reading:

This is from proactive 7/7/2021
The Applications for nanomaterials based on Andromeda halloysite-kaolin include carbon capture and conversion, energy storage, hydrogen storage and transport and water purification.
The patent application covers the processing pathways for conversion of the natural clay nanotube halloysite and halloysite-kaolinite admixtures of varying proportions, into selectively functionalised and chemically activated carbon nanomaterials.
Selective functionalisation refers to intended high technology uses for the nanomaterials, with positive signs seen so far for selective CO2 adsorption and for specific capacitance and energy storage.
Ongoing optimisation of the process continues for hydrogen storage, water and wastewater treatment and agricultural applications.

Below is some questions, I would like to ask James Marsh.

So what is the different between Carbon Capture and Hydrogen Storage and how does ADN's product help?

Now that we have 100% of nanotech, which one is more exciting and which one is the most advanced and likely to reach commercialisation. If we become successful at a commercial scale, what numbers could we be looking at?

I am interested in any GURU'S who have an opinion and can put it into a language blind Freddie can understand.
