Bricks made from carbon black? (generated as a byproduct of methane pyrolysis)

[Jasper Sky]

The global market for carbon black for tyres, ink, etc. is about 15 to 20 million metric tons per year. However, if the CCGT natural gas fired steam turbine market goes toward running on burning hydrogen gas generated from methane pyrolysis on a large scale, the total amount of solid carbon (carbon black) will greatly exceed this volume. 

It would be very useful to find a suite of marketable products with decent price per ton that can be made using carbon black as a key input (especially given that half the energy inherent in methane is lost as a result of the methane pyrolysis process). 

One question is whether carbon black can be pressed into solid bricks that have the strength characteristics required for use in the building trades. Preumably, this would require a binder of some sort (e.g. novel cement that is itself generated so as to absorb CO2 on a net basis). 

Does anyone know anyone working on large-volume marketable products with carbon black as a key input?

If not - any brainstorming ideas?

Black carbons (BC) like soot and charcoal consists all of more or less ordered graphene sheets. According to its electron exchange and adsorption properties BC is very helpful in waste water treatment and  for sustainable soil improvement in agroculture. The soil and waste water microbes  like BC as a habitat just because of these properties. By oxidative activation these properties of BC may even increased. Hence I see no problem to take a helpful use of BC in  these fields
