“Hydrogen from electrolysis, called green hydrogen, typically costs more than $5 per kilogram, or more than five times the price when produced from natural gas.”

“The U.S. Inflation Reduction Act offers an astounding subsidy of $3 to produce a kilogram of green hydrogen, three times the market price. Imagine a subsidy of $150,000 to purchase a $50,000 electric car or a subsidy of $12 to produce a $4 gallon of gasoline. There appears to be no end to the cash governments will pay to try to establish a hydrogen economy.”

World leaders tout “green hydrogen” as an essential fuel in the renewable energy transition. Today, heavy industries use huge amounts of coal and natural gas to produce products needed by society. Governments propose to replace hydrocarbon fuels with hydrogen fuel, using hundreds of billions of dollars in subsidies.…

“Koonin is … not REMOTELY qualified to dispute the conclusions of thousands of working scientists…. Koonin will say whatever he is paid to say.” (Paul Bryan, below)

“Bryan offers only  ad hominem attacks. Sadly, so characteristic of the public conversation about climate science.  If he’d made a specific criticism of what I said about climate science, it might be worth responding to.” (Koonin, below)

Emotions run high in the climate debate between the ‘settled-science’ alarmists and cautious, data-driven critics. There is every reason to listen and learn in a quite unsettled area (climate models?) and not be crude and offensive, much less engage in angry hate speech.

“Fossil fuel troll” … “You are simply shilling for the addiction model of energy and the dealers that profit from it” … “Your arguments are tired, old, oft-debunked pages from the Denier’s Playbook.…

This is the final installment of the course syllabus of Pierre Desrochers’ Energy and Society class.

Part I explored the course description as well as the videos and readings from the first two weeks of the class; Part II covered carbon-based energy. Part III yesterday was on electricity generated from non-carbon sources (Hydro, Nuclear, Renewables, Biomass).

This continues a series on the syllabus of Pierre Desrochers’ course at the University of Toronto Mississauga, Energy and Society, which gets my vote as the single best course on its subject in North America if not the world.
