There has not been anywhere near sufficient growth to become a profitable business opportunity for the two major players in the field -- WPRT & CLNE.
I don't understand the analogy to power and phone.
You and I have had many debates over the years about government subsidies of the power business. My position has been that without government subsidies, the electrification and the communication infrastructure would have never occurred that made the USA the world leader it became. You consistently oppose ANY AND ALL forms of government subsidy. Where would we be today without those subsidies and the Interstate Highway System paid for by either government subsidies or outight direct funding?
Because both are spending significant money expanding their infrastructure beyond the current demand. They are building to be in place to capture the future market.
If they were more worried about today's profits, they would not build out the infrastructure so far advance of the users. But then they would lose out on future market share. They are in it for the long haul.

I view it differently. It wasn't subsidies. It was a guarantee of profits paid by the users through creating regulated monopolies.
