speaking balance: gold is Shayle, purple is the guest (3 minute bins)
Sharpest disagreement ▶ 38:37 Rafi sharpens the claim on green premium limitations
When Kann qualifies that green-as-icing is mostly a US trend, Garabedian directly asserts that it is universally true everywhere except possibly China.
Hardest push from Shayle ▶ 18:23 Shayle challenges the industry use of the word modularizationKann pushes Garabedian to clearly differentiate chemical-scale modular systems from the classic solar model of repeating hundreds of small identical units.
Biggest teaching moment ▶ 14:00 Rafi breaks down why EPC scope doubles plant costsGarabedian details how site prep, buildings, chillers, and power electronics outside the stack scope balloon overall project CapEx to over three dollars a watt.
Shayle holds their own ▶ 2:43 Shayle articulates the three core failures of the first hydrogen waveKann provides an incisive industry overview detailing delivered cost overruns, poor market selection, and weak green premiums across the industrial landscape.

| Host Framing: The Green Hydrogen Reality Check | 7 | 1 | 0 | 0 | Host Shayle Kann sets a comprehensive framing for the green hydrogen hype cycle, delivered project costs, and industrial feedstock fundamentals before welcoming the guest. | |
| Analyzing Cost Inflation: Power Prices and CapEx Escalation | 4 | 7 | 1 | 0 | Garabedian educates the host on how wholesale power price escalations and doubling EPC capital costs pushed delivered hydrogen to six dollars per kilogram. | |
| Rethinking Plant Design Through High Density and Modularization | 7 | 5 | 2 | 3 | Kann probes deeply into electrolyzer CapEx stacks and tests the analogy of solar modularity, prompting Garabedian to explain why chemical-scale density beats distributed containerization. | |
| Mid-Show Sponsor Messages: Bloom Energy, Engie, and Energy Hub | 6 | 4 | 1 | 1 | After mid-roll sponsor spots, Garabedian discloses Electric Hydrogen's sub-one-thousand-dollar target and addresses Kann's question regarding Chinese manufacturing competition. | |
| European Regulatory Support and the Transition to Fossil Parity | 5 | 4 | 1 | 0 | The conversation covers European RED III and RFNBO transposition, with both agreeing that policy support is merely an on-ramp to unsubsidized fossil parity. | |

Kann: Industrial hydrogen represents a $70 billion annual market
“We already have a seventy billion dollar annual market using hydrogen in industry, predominantly in petrochemicals and ammonia production.”
Garabedian: Green hydrogen is slowly emerging from the trough of disillusionment
“Green hydrogen went through this just incredible Ballooning of the bubble, and I would say since then the bubble has burst, and you know, I can't say whether right now we're at the nadir of green hydrogen hype, or whether we're starting to come out of it. It f…”
Garabedian: Unsubsidized Green Hydrogen Costs Roughly $6/kg in Southern Europe
“If you look at the cost of making a kilogram of green hydrogen today, let's say in southern Europe, it might be unsubsidized. It might be maybe six dollars U.S. A kilo. I think rough numbers, that might be about right. That can be broken down Roughly fifty-fif…”
Garabedian: ERCOT green power prices doubled to $65/MWh amid AI demand
“If you look in West Texas and you were to sign a solar and wind kind of affirmed green power purchase agreement in, in Texas and Urquhart territory three years ago, you might've paid 35 dollars a megawatt hour for that product. Today you're paying 65, maybe mo…”
Garabedian: Western green hydrogen plant capital costs doubled to over $3/W
“We've seen those capital costs go from You know, an early promise of something like 1500 dollars a kilowatt, buck 50 a watt, to now even over three dollars a watt of capital cost.”
Garabedian: EPC accounts for roughly half of hydrogen plant installed costs
“And in a typical project like we're discussing, roughly half of the total installed cost goes to the EPC.”
Garabedian: Deploying hundreds of small containerized electrolyzers is highly cost-inefficient
“The idea of integrating onto a site hundreds and hundreds of very small containerized electrolyzers, it turns out to be quite expensive. And in no small part, it's expensive because it's very hard to drive the cost out of those units, but also because the foot…”
Garabedian: Electric Hydrogen prices European plants just over $1,000/kW installed
“So, we're pricing in the European market today with a total installed cost just north of a thousand dollars a kilowatt. Inclusive of EPC. That's everything from the substation, the civil works, all of our equipment, the installation and commissioning.”
Chinese electrolyzer systems in Europe cost just over $1,500/kW installed
“We see integrators building or promising to build using Chinese equipment systems in the European market at a total installed cost, you know, right around maybe a little north of 1500 dollars a kilowatt.”
Garabedian: China's low-cost solar manufacturing playbook will fail in hydrogen
“So long story short I don't think the same game that worked in solar works in green hydrogen.”
Garabedian: Subsidized green molecule market is unsustainable long term
“That is not a sustainable market in my view in the long term. It's a necessary first step for the P to X or green molecule industry to get going.”
Garabedian: Brazil imports over 90% of its nitrogen, primarily from Russia
“Brazil, it turns out, imports over 90% of its nitrogen. Its biggest import partner for fertilizer is actually Russia.”
Garabedian: Electric Hydrogen can produce Brazilian ammonia at $700-$750/ton today
“Brazil's grid is around 90% green already. And power prices at least away from the coastal economic centers are quite low. 30 to 35 dollars a megawatt hour. That in and of itself allows us to make on the order of seven to 750 dollar a ton of ammonia today with…”
Garabedian: Electric Hydrogen will beat fossil hydrogen costs by early 2030s
“Now, if you take our technology roadmap a little further out, and you think about scale and also improvements we have in our, coming in our technology, along with what we expect to see in terms of continued cost reduction in wind and solar, we think we can get…”
Garabedian: Next five years of green hydrogen will be policy-driven European projects
“So I think the next five years looks like very, very tactical kind of one-off projects that are policy-driven in places like Europe. That have the policy frameworks in place or emerging to motivate consumption of these molecules.”
