Yes. You could produce biohydrogen from a range of these different biomass feedstocks. When I refer to these feedstocks, they could be wheat, straw, the whole tree biomass or forest residues. Then there are different processes for how you can produce this hydrogen, which could be based on gasification or pyrolysis. The typical range of the cost of production that you are looking at is about $3 to $4 per kilogram of hydrogen. If I compare this with the typical cost of natural gas or SMR-based hydrogen production, you are still looking at a twofold to threefold higher cost compared to natural gas.
In terms of GHG emissions, if you look at the GHG emissions for biomass feedstocks and any biohydrogen compared to natural gas, they are much lower. You are looking at a significant reduction in those numbers, especially on the forest side. People talk about hydrogen from SMR, but they integrate CCS—carbon capture and storage—to produce blue hydrogen. We call that natural gas-based hydrogen “blue hydrogen”. If you compare that with the biomass—so SMR and CCS with biomass—you're looking at an almost 50% reduction in the case of the biomass-based hydrogen. Those are the kinds of hydrogen production numbers that we have come up with for a range of different feedstocks.
