This isnt about market power. Hydrodesulfurization requires high pressure hydrogen, forced to react with vaporized fuel at high temperatures over catalysts.
That hydrogen comes from steam reforming cat cracker offgas and/or natural gas.
So more process streams get consumed. They have to be consumed because HDS is not selective, and thus they open every aromatic ring and double bond before they actually access the sulfur in the benzothiophene type groups.
So you need multiple extra unit operations, working in more harsh regimes, which drive capital and operational cost.
My point was about the economics of the price increase associated with low-sulfur gasoline, not the chemistry of fuel. In this case, consumers are those who buy fuel.
What I mean by market power is the more consumers you have of a product, the lower the price of a good can be. There are other obvious economic forces at play, but in general the larger the market, the more competition is available amongst sellers which can control costs.
