"If we lived in some imaginary post-partisan Bizarro world where we had the prospect of spending as much money on clean energy as we ought to based on the realities of climate science and peak oil, then cutting the hydrogen doesn’t wouldn’t be needed. We’d just increase the R&D and deployment programs for energy efficiency and renewable energy and electric drive vehicles several times.
Similarly, if the anti-science, pro-pollution conservatives and their enablers hadn’t killed the climate and clean energy jobs bill, again, we would have had more than enough money to fund even the implausible clean energy strategies.
But we’ve entered a period where political and budget realities mean we have to focus resources on the clean energy technologies and low carbon strategies that deliver the biggest bang for the buck. Hydrogen not only has massive technological problems that will require large amounts of continued R&D funding. It has a staggering infrastructure costs that would require tens if not hundreds of billions of dollars to jumpstart a genuine hydrogen economy."
