Interesting article on Hydrogen and stationary engines (link below). While in Arkansas I asked Chad if it were possible that the HyRoad could theoretically replace DEF systems altogether. I am not sure if that was a brand new thought or not, but it is mentioned in the last shareholder newsletter. DEF units are required due to incomplete combustion that the HyRoad happens to correct. I would think also that engines could be brought into Tier 4 compliance simply with the application of a HyRoad unit. Of course there would be opposition to this. Just something to consider. Still holding a investing more as I am able. HBRW.
