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.

RIZON class 4 and 5 electric MD trucks arrive in Canada

RIZON class 4 and 5 electric MD trucks arrive in Canada

Daimler’s new, all-electric truck brand made its Canadian debut this week with the official market launch of its battery electric class 4 and 5 medium duty work trucks.

After making its North American debut at the 2023 ACT Expo in Anaheim, California, Daimler Truck’s RIZON brand has continued on a steady march towards production with initial preorders set to open this June. But it won’t just be Americans who can order a new RIZON electric box truck – Canadians will be able to add them to their fleets at the same time.

“Canada is very advanced regarding green energy and infrastructure and is a natural next step for RIZON’s second market,” explains Andreas Deuschle, the Global Head of RIZON. “We are very happy to bring our zero-emission solution to Canadian customers. They are proven OEM trucks with the latest technology from Daimler Truck.”

Modernism and mandates

Along with California and a handful of other US states, the Canadian government has plans to limit (or outright ban) the use of diesel trucks on its roads. In the case of Canada, the nation has committed to a zero emissions goal by 2050 – but Daimler could have gotten there without launching a new brand.

So, why is Daimler launching a new brand?

RIZON is about reaching new customers with a chassis that’s been designed from the ground-up to be an EV. These customers might be new to Daimler, or looking to replace an aging fleet of Isuzu or (more likely) Mitsubishi Fuso cabovers with something a little more modern.

What they’ll find in a RIZON, then, is a smooth, quiet, and car-like ride that will make the “step up” from something like a Ford E-Transit easier than they might think.

Our own Jameson Dow got to drive a RIZON e18L model at an event hosted by Velocity Truck Centers at Irwindale Speedway last year, and came away impressed with the truck’s smooth acceleration and adjustable regenerative braking.

RIZON will offer four model variants for Canadian customers, the e16L, e16M, e18L, and the e18M, with a range of configurations and options ranging from 7.25 to 8.55 ton GVWRs.

Electrek’s Take

There’s definitely a place in the North American market for an agile, easy-to-drive medium duty truck like the RIZON, and Daimler’s nationwide network of Freightliner and Western Star dealers should give first time MD buyers a bit more peach of mind than they might get from a startup brand.

You can check out the specs on each of the RIZON electric models, below, then let us know what you think of these new cabover EVs in the comments.

777 hp electric overland concept from Italdesign bows in Beijing [video]

777 hp electric overland concept from Italdesign bows in Beijing [video]

The all-new, all-electric Italdesign Quintessenza concept is a high-tech Italian take on the Porsche Dakar concept that’s just begging to be put into production.

Making its debut at the Beijing Auto Show, the Italdesign Quintessenza concept embodies both the dynamic prowess of a GT and the versatile adaptability of a pick-up truck. At least, that’s what its makers say. And, if your idea of a pickup truck leans more towards “Subaru Brat” than “Ford F-150 Lightning,” that’s probably right!

The rear section of the Quintessenza converts from a “hatchback” to an open “pickup” bed in true Brat fashion. The rear seats are designed to flip 180-degrees backwards, providing a rear-facing, panoramic “stargazing” mode that promises, “(the) experience and feeling of connection with nature and the outside world.”

Stargazing mode

In its more conventional GT “mode,” the Quintessenza is arguably the best-looking Italdesign concept to come out in years, with vertical lighting elements up front and aggressively-sculpted rear haunches that this writer thinks would be a natural for Audi.

Those design elements aren’t just aesthetic – they’re loaded with electronics. “Two aerodynamic fins that integrate the ADAS systems are present on the upper back of the roof, at the level of the C-pillars,” reads the official release. “They map the surrounding environment when the satellite signal is poor, and offer multifunction lights indicating the car’s driving mode and braking when the hard top is removed.”

Quintessenza vertical elements

So, what kind of vehicle is the Italdesign Quintessenza? Is it a true overland GT, in the style of the Porsche Dakar or 911 SC/RS (the rally car that became the 959)? Is it a high-end spin on the classic Subaru Brat? A futuristic Ute for traversing the Australian outback? Or is it something else entirely?

That’s above our pay grades – but you, dear readers? You guys know what’s up, so check out the official Quintessenza launch video (below), then let us know what you think of Italdesign’s latest in the comments section at the bottom of the page.

The new Momentum Cito E+ dares you to leave the car at home [Video]

The new Momentum Cito E+ dares you to leave the car at home [Video]

All the cool suburbanites are already taking their kids to school, loading up at the farmers’ market, and making deliveries on clever and capable cargo e-bikes, but the new Momentum Cito E+ from Giant raises the cargo bike bar even higher — and makes leaving the car at home easier than ever.

Momentum is a new brand of “lifestyle” e-bikes from Giant Group designed to deliver premium features to customers while still hitting that $3,000-4,000 market “sweet spot.” Their latest bike, the all-new for 2024 Cito E+ utility bike, does just that, coming to market with a premium battery, Bluetooth technology, a suite of high-end safety features, and a $3,200 starting price.

Premium battery

Getting the most out of your e-bike often means getting the most out of your battery — and Momentum absolutely gets that. The Cito E+ ships with a 780 Watt-hour Panasonic battery pack with 22700 cells that have been optimized for e-bike use.

Compared to other ebike batteries with similar power ratings, the Momentum’s Panasonic battery promises to be lighter and more durable, with superior IPX7 weather protection, thermal regulation, and other safety features built-in (in fact, Panasonic was the first e-bike supplier to score a UL safety rating for its batteries).

The battery is easily removable for charging at home or in an office, but it can be charged while it’s in the bike, too. Either way, charging won’t take long — from 0 to 80% of charge (approx. 60 miles) of range is available in 3.5 hours, while a full (75 mile) charge takes less than 5 hours.

Connected cargo bike

As our test rider highlights in the video (above), the Momentum Cito E+ uses a proprietary battery management system, or BMS, to monitor the battery pack for maximum efficiency and reliability down to the individual cell level.

The BMS uses Bluetooth connectivity to transfer battery health data, state of charge, and other important information straight to the RideControl app, which enables the bike’s owner to get an in-depth look at the overall state of their e-bike and provides valuable diagnostic data to both the technicians tasked with servicing the bike and Giant themselves, to help develop even better e-bikes in the future.

That connection to Giant Group is a huge potential benefit to Momentum Cito E+ buyers, by the way, as it gives them access to support from more than 1,200 brick and mortar Giant dealers across the US alone (above).

That’s a serious advantage that online-only bike brands simply can’t match.

Safety first … and maybe second, too

Momentum’s commitment to safety doesn’t stop at the battery. The Cito E+ features confidence-inspiring 4 piston hydraulic disc brakes and a heavy duty suspension for predictable handling even under heavy loads — important if you have to suddenly haul the bike down from its electronically assisted 28 mph top speed with precious kids and cargo on the back.

LED head and taillights with a lever-activated taillight ensure Cito E+ riders will be seen, too, helping you stay safer after hours.

Accessories and add-ons

Momentum’s Cito E+ offers a comprehensive selection of accessories to help optimize it for each rider’s unique use case — whether that’s hauling up to 132 lbs. of cargo on the rear rack and 33 lbs. on the optional front basket (shown, above), or adding 2 Thule Yepp Maxi seats and getting the little ones to school five times a week.
