Our new report from Lorenzo Sani finds CO2 emissions from Blue & Gas- projects could be 2-3x higher than reported - when considering upstream from gas extraction, processing & transport https://buff.ly/4c7q2KF

"The current plan puts roughly 15 of MACH2’s 25 projects in southeast . These include facilities that will produce using steam reformation, nuclear energy, and renewable energy sources such as solar.

Spotlight PA interviews with a dozen stakeholders and a review of feedback from public meetings overwhelmingly show concern, rather than enthusiasm."

Honest question: I measure gases as a career, and I’m always fixing leaks in my instruments*. How do people who push #hydrogen as a home heating solution propose to avoid catastrophic leaks?

*I use Swagelok fittings, the same ones used on airplanes and in industrial settings.

" has emerged as a leader in producing the cheaper way using abundant supplies of natural gas without capturing the carbon dioxide.

Little hydrogen is made from gas with or from water in the state — or the rest of the country.

Environmental groups worry the federal funding will prop up oil and gas companies, when the emphasis should be on making hydrogen from water or creating clean power another way."

‘Blue’ Hydrogen Could Produce 50% More Warming than Burning Fossil Fuels

"[Canada] “is betting big on #BlueHydrogen, a fossil fuel-derived chemical masquerading as an energy solution."

This research should finally lay to rest the unfounded hope that creating incentives for fossil #hydrogen production in Canada is any kind of solution for the climate, or for economic development.”

#Germany's steel manufacturers turn to #hydrogen for low-carbon steel.

" Global #steel production today accounts for at least 7 per cent of global greenhouse gas emissions. In Germany, it emits more than a quarter of the country’s total industrial carbon dioxide."

Today in Labor History January 31, 1950: President Truman ordered the development of thermonuclear weapons (Hydrogen bombs). The U.S. tested the first thermonuclear weapon in 1952. It was developed by Edward Teller. H-bombs consist of a nuclear fission primary stage, much like older atomic bombs. The fuel for this stage is usually 235U or 239Pu. This is followed by a nuclear fusion reaction using the heavy hydrogen isotope deuterium and tritium. Modern thermonuclear weapons use lithium deuteride. The nuclear fission stage creates a temperature of over 100 million Kelvin (180 million degrees Fahrenheit), flooding the radiation channel with X-rays. The X-ray energy implodes a plutonium spark plug, compressing the secondary stage and driving the plutonium into a supercritical state that drives a fission chain reaction. The fission products heat the thermonuclear fuel to 300 million Kelvin, igniting the fusion reactions.

    MAN CEO Vlaskamp: “Green hydrogen is not available for transportation and there is no point in switching from diesel to hydrogen if the energy source is not sustainable.”

    Just true.

    The industry knows it. All the talk about hydrogen as an alternative to E-traction - it's just a distraction to slow down the transformation in order to sell fossil fuels even longer.

    Green hydrogen was once an interesting idea. But since 99% of hydrogen on the market is simply fossil fuel in disguise, it seems that those promoting hydrogen as the future are the very people who are selling us fossil fuels.

    @WolfgangFeist Batteries are just a distraction from serious discussion about green heavy transportation.

    The CEO of MAN is just defending his parent company's bad business decisions. BEV trucks are destined to fail due to the fundamental contradiction of trucking and batteries. They will go with trucks, either by force or by realizing the obvious.

    The main reason the hydrogen hype is in overdrive: Big Oil n Gas wants to make money converting fossil gas into hydrogen.

    "Before looking at why legacy #automotive companies, resource tycoons and the politicians that represent them, have been such huge advocates for hydrogen-powered vehicles, it’s important to firstly outline why #hydrogen cars are so fundamentally flawed and will never come close to competing with #battery electric vehicles."

    There is a place for . But blindly applying it everywhere turns it into a solution looking for a problem.

    "According to the Renewable Energy Institute (REI), a Japanese environmental think tank, this push to use hydrogen in every conceivable energy sector is actually doing more harm than good. "

    Everybody knows - I hope everybody knows - that fully two thirds of the energy you pour into the gasoline / diesel tank of your ICE car gets lost as heat. It's like buying three pounds of vegetables and immediately throwing out two before you start to cook with the remaining pound.

    Turns, out, cars have the same inefficiency: 34% - 37%.

    Battery e-cars have a 87% efficiency. The same solar field can power nearly three times more EVs than hydrogen cars.

    It is much more efficient and cheaper to pump the #renewable electricity directly into a vehicle #battery."

    It was always the industry pushing for hydrogen even in places where it makes no sense. Now has the receipts.

    How the hype fizzled out

    "A seductive hydrogen narrative has been replaced with one in which the fuel’s complexities and limitations are more apparent. But even its much reduced role could still prove challenging to deliver."

    – Despite all the subsidies, the production is way less than needed for the 2030 goal;
    – It's expensive, $200 /MWh
    – Other tech has developed faster, e.g. batteries
