The first part of this analysis on the recently released life-cycle assessment of “blue” hydrogen covered the provenance and background for the paper, as well as the significant and questionable assumptions that the authors make about both expected demand for “blue” hydrogen and the scalability of carbon capture and sequestration it would demand. This second half continues the analysis of assumptions and statements in the paper.

“In general, large-scale blue hydrogen production will be connected to the high-pressure natural gas transmission grid and therefore, methane emissions from final distribution to decentralized consumers (i.e., the low-pressure distribution network) should not be included in the quantification of climate impacts of blue hydrogen.”

The first problem with this is the assumption that massive centralized models of hydrogen generation will be preferable to the current highly distributed creation of hydrogen at the point of consumption. The challenges with distributing hydrogen are clear and obvious, so it’s interesting that they make an assumption that is completely contrary to what is occurring today, and wave away the significant additional challenges — including carbon debt — of creating a massive hydrogen distribution system essentially from scratch.

This also assumes that there will continue to be a distribution network for natural gas. Electrification of heat will continue apace, eliminating this market. But supposing that it does continue, this assumes that perpetuating the leakage problem is in line with actual climate mitigation, which is decidedly not the case. This is not the point of the paper, but is in line with the rest of the paper’s assumptions.

“… natural gas supply must be associated with low GHG emissions, which means that natural gas leaks and methane emissions along the entire supply chain, including extraction, storage, and transport, must be minimized.”

This is in context of what requirements “blue” hydrogen would have to meet in order to be low-carbon hydrogen per the paper.

I agree with this statement, but further say that there is zero reason to believe that this will be widely adhered to as the fossil fuel industry is already lagging substantially in maintenance with declining revenues in regions impacted by the Saudi Arabian-Russian price war, the history of the industry consists of a Ponzi-scheme of paying for remediation with far distant and non-existent revenues — witness the $200 billion in unfunded remediation in Alberta’s oil sands as merely the tip of the iceberg, and as long-distance piping and shipping of natural gas requires a great deal of expensive monitoring and maintenance to maintain that standard.

In other words, while the statement is true as far as it goes, it is so unlikely to be common as to be irrelevant to the actual needs of the world for hydrogen, something that the authors barely acknowledge.

“Our assessment is that CO2 capture technology is already sufficiently mature to allow removal rates at the hydrogen production plant of above 90%. Capture rates close to 100% are technically feasible, slightly decreasing energy efficiencies and increasing costs, but have yet to be demonstrated at scale.”

Once again, 90% is inadequate with over a thousand billion tons of excess CO2 already in the atmosphere. Second, carbon capture at source has been being done since the mid-19th century. It’s not getting magically better. The likelihood that approaching 100% capture rate technologies will be deployed by organizations and individuals who think 90% is good enough and are likely to be rewarded handsomely for achieving that level approaches zero. After all, Equinor has received what I estimate to be over a billion USD in tax breaks for its Sleipner facility, which simply pumps CO2 they extracted back underground, and ExxonMobil touts its Shute Creek facility as the best in the world when it pumps CO2 up in one place then back underground in another place for enhanced oil recovery, benefiting nothing except their bottom line.

Removal of carbon from the atmosphere to draw down CO2 levels toward achieving a stable climate will not be realized by “good enough,” and close to 100% will be so rarely realized globally that it’s not worth discussing.

“It is important to reiterate that no single hydrogen production technology (including electrolysis with renewables) is completely net-zero in terms of GHG emissions over its life cycle and will therefore need additional GHG removal from the atmosphere to comply with strict net-zero targets.”

The authors appear to think that the current CO2e emissions from purely renewable energy are going to persist. As mining, processing, distribution, manufacturing and construction processes decarbonize, the currently very low GHG emissions of renewables full lifecycle will fall. This is equivalent to the common argument against electric cars, that grid electricity isn’t pure. It’s also a remarkable oversight for a group of authors committed to a rigorous LCA process.

The argument that “blue” hydrogen at its very best in the best possible cases will be as good as renewably powered electrolysis as it decarbonizes fails the basic tests of logic and reasonableness.

“… natural gas with CCS may be a more sustainable route than hydrogen to decarbonize such applications as power generation.”

This is so completely wrong that it’s remarkable that it made it into the document. First, there is no value in hydrogen as a generation technology. That’s a complete and utter non-starter beginning to end, making electricity vastly more expensive to no climate benefit. Secondly, all bolt-on flue capture programs for electrical generation have cost hundreds of millions or billions and failed. They increase the costs of electrical generation to the level where it was completely uncompetitive in today’s markets.

When wind and solar are trending to $20 per MWh, long-distance transmission of electricity using HVDC exists in lengths thousands of kilometers long and underwater around the world, and there are already 170 GW of grid storage and another 60 GW under construction at the bare beginning of the development of storage, assuming that either natural gas with CCS or hydrogen have any play in electrical generation makes it clear that the authors are simply starting with the assumption that natural gas and hydrogen have a major part to play in the future, and have created an argument for it.


The authors’ argument boils down to that in a perfect world, perfectly monitored and perfectly maintained, “blue” hydrogen would be similar in emissions to green hydrogen today, ignoring the rapidly dropping GHG emissions per MWh of renewables and ignoring that the world of fossil fuels in no way adheres to the premise of perfect monitoring and perfect maintenance.

The authors are performing a life-cycle assessment focusing on greenhouse gas emissions, and it is not scoped to include costs. Having reviewed the costs of the technologies that they are proposing for this hypothetical perfect “blue” hydrogen world, they are vastly higher than just not bothering, shifting to renewables rapidly and electrifying rapidly.

As a contribution to the literature on what will happen in the real world, this is a fairly slight addition, one which is being promoted far beyond its actual merit by the usual suspects.

The Chevy Equinox EV is GM's breakout star, but that's not the only surprise

The Chevy Equinox EV, or “America’s most affordable 315+ range EV,” as GM calls it, is red-hot. Thanks to the electric Equinox, Chevy is solidifying its position as the fastest-growing EV brand in the US. The Chevy Equinox EV helped GM’s electric vehicle sales more than double in Q2, but there’s more to the story.

The Chevy Equinox EV is charging up GM’s sales

GM surpassed Ford and Hyundai Motor last year to become the second-best EV seller in the US. This year, it’s closing the gap with Tesla.

Led by the Equinox EV, GM’s EV sales more than doubled in Q2, and Chevy solidified its position as the number two electric vehicle brand.

Chevy’s electric vehicle sales surged 134% in the first half. In Q2, Chevy sold 17,420 Equinox, 6,549 Blazer, and 3,056 Silverado EVs. Through June, GM has now sold 27,749 Equinox, 12,736 Blazer, and 5,439 electric Silverado models. The Chevy Equinox EV is expected to be one of the top three best-selling EVs in the US.

Although Chevy’s new EVs are a hit, they are not the only growth driver behind GM’s success. The American automaker sold a total of 46,280 electric vehicles in Q2, representing a 111% increase from the same period in 2024.

GM’s share of the EV market in Q2 was approximately 16%, with growth across the Chevy, Cadillac, and GMC brands.

Cadillac notched its 12th consecutive quarter of retail sales growth, achieving its highest market share since 2014.

With a full lineup of electric SUVs, including the entry-level (Optiq), midsize (Lyriq), and full-size (Vestiq and Escalade IQ), nearly one in four Cadillac models sold were EVs. GM sold 3,224 Cadillac Optiqs, its new entry-level EV, 5,017 Lyriqs, 1,744 Vistiqs, and 1,810 Escalade IQs in the second quarter.

GMC-Sierra-EV-affordable

After launching the new 2026 Sierra EV with an over $27,000 price cut from the 2025 model year, GMC sold over 1,500 electric Sierra models. Even the GMC Hummer EV is seeing more demand, with 4,508 units sold in Q2, up 54% from last year.

Starting at under $35,000 with up to 319 miles of range, it’s no wonder the Equinox EV is selling like hotcakes. With leases starting at just $289 per month, it’s a great deal right now. Who knew an affordable EV with over 300 miles of range would sell?

Clean energy stocks jump after tax on solar and wind projects is removed from Trump’s big bill

Clean energy stocks jump after tax on solar and wind projects is removed from Trump's big bill

Clean energy stocks rose on Tuesday after a tax on solar and wind projects was removed from the Senate version of the One Big Beautiful Bill Act.

Shares of NextEra Energy, the largest renewables developer in the U.S., rose nearly 3% after the Senate narrowly passed President Donald Trump’s bill on Tuesday. AES, a leading renewable provider, rose almost 2%. The megabill will now go to the House of Representatives, where lawmakers will consider the Senate’s changes.

The clean energy industry was surprised and outraged to find over the weekend that a tax on wind and solar projects had been inserted into a version of the Senate legislation. The tax applied to projects that use components from foreign entities of concern above a certain threshold. Foreign entities of concern is widely understood to basically refer to China.

The American Clean Power Association and Solar Energy Industries Association told CNBC that the tax was struck from the Senate legislation. ACP had described the tax as punitive and warned that it would add up to $7 billion to the solar and wind industry’s tax burden.

The Invesco Solar ETF (TAN) over the past three months.

The benchmark Invesco Solar ETF (TAN) was up about 4%, while the iShares Global Clean Energy ETF (ICLN) was trading more than 1% higher after the legislation passed.

Shares of First Solar, the largest solar panel manufacturer in the U.S., slipped less than 1%. Sun tracker manufacturers Array Technologies and Nextracker jumped more than 11% and about 5%, respectively.

Residential solar installer Sunrun rose 9% while inverter manufacturers SolarEdge and Enphase were up about 8% and 4%, respectively.

But the Solar Energy Industries Association cautioned that the improvements in the Senate bill are “limited” and the legislation overall is still harmful to renewable energy.

“This legislation undermines the very foundation of America’s manufacturing comeback and global energy leadership,” CEO Abigail Ross Hopper said in a statement. “If this bill becomes law, families will face higher electric bills, factories will shut down, Americans will lose their jobs, and our electric grid will grow weaker.”
