Adsorbed Synthesis Gas – light weight tankers for non fossil fuel shipping fuel

I am trying i to find a supplier of ready made -lightweight ro/ro tanktainers that will hold my own supply of clean syngas (no inerts) I make coconut shell activated carbon with high microporosity and hardness. 

Alternately  am looking for someone who has experience working with ASG in particular- making portable tanks- also trying to work out the totals per M3 for capacity, fuel value . The gas will be mixed with HSD fuel in 75/25 gas to fuel ratio on main ship propulsion engines.  Trying to cut the excruciating dependence and high costs of running FF in general and inter island shipping in particular- this is our lifeline and we are being strangled by new generation of the old seven sisters.  Any ideas gratefull recieved.
