| Why Clean Hydrogen is Indispensable for Net Zero | 5 | 4 | 0 | 0 | Lacey references Basham's Bloomberg economic modeling regarding cost parity between green, grey, and blue hydrogen. Basham details why hydrogen is critical for the final 5-6% of hard-to-abate industrial emissions. | |
| Massive Electricity Demands and Grid Integration Challenges | 5 | 6 | 0 | 0 | Lacey probes potential bottlenecks that could derail the hydrogen economy. Basham provides extensive numerical evidence regarding power draw, showing electrolyzers could consume one-third of global electricity by 2050 and compete with other clean energy demands. |
Statements from this episode (22)
Environmental groups run Washington Post ad demanding stricter hydrogen rules
“A number of green groups, including the Environmental Defense Funds and NRDC and Evergreen Action, were posting an ad in the Washington Post saying, don't spend billions on pollution, keep climate pollution out of the clean hydrogen tax credit. So basically ar…”
BNEF estimates over $120 billion in subsidies for announced hydrogen projects
“We estimated, I think, over a hundred twenty billion dollars in subsidies that could go to all the announced clean hydrogen projects.”
Unregulated grid-powered hydrogen could double emissions compared to fossil fuels
“Without any restrictions on hydrogen production from grid electricity, the emissions of hydrogen production in the U.S. Could be double that from producing just hydrogen from fossil fuels directly.”
US consumes roughly ten million metric tons of hydrogen annually
“The U.S. Currently uses about ten million metric tons of it.”
Announced clean hydrogen projects through 2030 total 8 million metric tons
“Based on the announced projects that we are seeing out to 2030 we see about eight million metric tons of clean hydrogen, so both forms proposed, which is about 80% of what the U.S. Is using today and about 80% of the U.S. DOE's target as well.”
Air Products backs strict hydrogen rules while Plug Power opposes them
“Companies were really interested in producing large volumes of clean hydrogen, like air products, and manufacturers of electrolyzers like electric hydrogen have come out in favor of very stringent standards on, on hydrogen production. Whereas others, like Plug…”
NextEra Energy Advocates Phasing In Clean Hydrogen Grid Rules Over Time
“And then there's a bunch of companies in the middle of this debate which want some rules on clean hydrogen production from the grid, like NextEra Energy in the US, but are arguing for a phase in of these requirements over time.”
Unregulated grid-powered hydrogen would add 200 million metric tons of CO2
“The worst case is really that there's really no requirements for hydrogen production from grid electricity, which means, in the end, you end up creating more emissions than what fossil hydrogen production is already creating today. So let's say the U.S. Actual…”
Strict hydrogen rules could reduce emissions by 95% versus fossil fuels
“Stringent requirements, on the other hand, mean that your, that hydrogen production using electrolyzers is actually emissions reducing, potentially 95% lower than the fossil alternative that you have, and potentially even more if you consider all the positive …”
US hydrogen rules will likely adopt three pillars with phase-ins
“The U.S. Guidance is likely to follow these three pillars that are outlined on additionality, temporal matching, and deliverability or geographic correlation with some sort of phase in, particularly on the requirement for additionality, so for new renewable en…”
EU hydrogen import demand will set global production standards
“Because the EU is looking to become the largest importer of clean hydrogen globally that means that their rules really, really affect hydrogen production elsewhere, particularly for markets looking to export hydrogen to Europe and basically set a global standa…”
Final 5% to 6% of net-zero emissions abatement relies on hydrogen
“You can get very far in terms of emissions abatement just with clean power and electrification of end uses alone. That gets you, like, 80, 90% of the way. Then adding carbon capture and storage also gets you much closer. But the final five, six percent or so o…”
Hydrogen is essential to produce primary steel and reach net zero
“And in sectors that have no other alternative to using hydrogen, for example, as a fuel and heavy transport like ships and planes for steel production, hydrogen is one of the few options to produce primary steel. So it's absolutely essential that hydrogen gets…”
Green hydrogen will become cheaper than blue hydrogen by 2030
“If we scaled it up to potentially hundreds of gigawatts by the end of the decade and going further, we expect the cost of that equipment to decline by 50, 60, or 70% or so, which really drives cost reductions of Green or renewable hydrogen below the cost of pr…”
Producing a kilogram of green hydrogen requires 50 kWh of power
“Each kilogram of hydrogen production today requires about 50 kilowatt hours of electricity to be supplied to that electrolyzer to produce that electricity.”
Hydrogen electrolyzers convert only around 70% of electricity input
“Electrolyzers are also not that efficient, only converting about 70% or so of the electricity that you supply into energy in the form of hydrogen.”
Hydrogen electrolyzers could consume one-third of global power by 2050
“By twenty-fifty, under a net zero scenario, electrolyzers producing hydrogen take up a third of all electricity demand almost, just to power power themselves to produce hydrogen. So all of global, a third of all global electricity demand.”
2030 green hydrogen goals would consume 16% of new renewables
“If about a 20 millimetric tons or so of clean hydrogen are produced globally by the end of the decade, And we got to about 16% of all the renewables we expect to deploy this decade will just go to the production of hydrogen.”
Global electrolyzer sales stand at one gigawatt annually, mostly in China
“We're selling about a gigawatt of them every year. Most of those are deployed in China.”
Largest operating electrolyzer outside China is only 20 megawatts
“The largest electrolyzer operating outside of China is just 20 megawatts in size.”
Proposed manufacturing can meet hundreds of gigawatts of demand by 2030
“In terms of, if you look at the supply chain we think there's enough proposed electrolyzer manufacturing capacity and proposals to do, build more electrolyzers that you could supply all those few hundred gigawatts of electrolyzers by the end of the decade if a…”
