the scores for every segment, with the reasoning behind each
| Chapter | Topic | Shayle as informed peer | Guest teaching | Guest disagreement | Shayle pushing back | Why |
|---|---|---|---|---|---|---|
| Episode Preview: Historic Loan Guarantee for Hydrogen Storage | 0 | 0 | 0 | 0 | This introductory segment consists of teaser audio, sponsor advertisements, and the host providing background context on the ACES hydrogen project before welcoming the guest. | |
| Structuring the ACES Hydrogen and Power Project | 5 | 3 | 1 | 2 | The host asks Jigar to explain how the ACES project is structured and tests his understanding of the offtake model. Jigar clarifies that the project is underwritten directly against a power capacity contract rather than merchant hydrogen sales. | |
| Coal Repowering and Regional Grid Power Flows | 6 | 2 | 1 | 3 | Shayle points out that coal plants operate as baseload rather than peakers, prompting a technical discussion on how repowering frees up transmission capacity. Shayle draws an apt comparison to nodal price dislocations seen in Texas grids. | |
| Technical De-Risking and DOE's Technical Role | 5 | 4 | 1 | 2 | Shayle probes the technical risk profile of storing hydrogen in salt caverns versus the electrolysis equipment. Jigar explains why commercial banks hesitate without DOE's technical de-risking and thousands of staff scientists. | |
| Commercial Break: Community Power and Business Energy | 6 | 3 | 2 | 4 | Following mid-roll ads, Shayle questions why underground salt cavern storage is necessary if electrolyzers could theoretically run on demand. Jigar explains the cost necessity of running electrolyzers baseload to achieve sub-four-dollar hydrogen alongside seasonal grid buffering. | |
| Hydrogen Hub Logistics, Transport, and Fertilizer Economics | 6 | 4 | 2 | 2 | The conversation shifts to the logistics of hydrogen transportation versus co-locating industrial consumption near production sites. Jigar highlights the disrupted fertilizer supply chain and explains why green ammonia is currently profitable without subsidies. | |
| Electrolyzer Utilization, CapEx Amortization, and Electricity Pricing | 7 | 4 | 3 | 6 | Shayle challenges the premise of intermittent industrial processes using curtailed renewables, arguing that high CapEx amortization forces continuous 24/7 operation. Jigar counters by pointing out that real-world LMPs already offer low power prices for over ninety percent of annual hours. | |
| Battery Diversification and System-Level Decarbonization | 6 | 5 | 3 | 4 | Shayle raises concerns about lithium-ion supply crunches stalling near-term stationary grid battery deployment. Jigar dismisses the five-year delay anxiety by arguing alternative chemistries like iron and zinc are already commercializing. | |
| Investment-Grade Structuring and Developer Option Value | 6 | 3 | 2 | 2 | Jigar explains how ACES achieved an investment-grade rating and created strategic option value for renewable developers to sell molecules instead of curtailed electrons. Shayle neatly encapsulates the concept as selling molecules rather than electrons. | |
| Upcoming Loan Programs Office Sectors and Pipeline | 4 | 2 | 1 | 1 | In a quick wrap-up, Shayle asks about upcoming sectors in the LPO pipeline, and Jigar lists manufacturing, critical minerals, virtual power plants, and sustainable aviation fuel. |
Statements from this episode (18)
Kann: Total US energy storage deployed today is under two gigawatt-hours
“For reference, we have a total of less than two gigawatt hours of energy storage in the US overall.”
DOE issued conditional commitment for $500M+ loan to Utah ACES project
“It's notable that the LPO just issued a conditional commitment to guarantee an over five hundred million dollar loan to the ACES project, which would become the largest green hydrogen hub in America by a long shot.”
Shah: DOE is underwriting ACES hydrogen loan solely to power offtake
“That's exactly right. We're underwriting to the power, and, you know, and the renewed generation facility will be owned by Intermountain Power Agency and so, so that, so, so that is what we're underwriting to.”
Shah: DOE loan exclusively funds ACES hydrogen storage, not gas plant
“Our money is not being used at all for that. So our money, the project that we're funding is an electrolyzer project using a salt dome as storage, right? So none of our money is going to a new natural gas facility.”
Shah: Battery storage will relegate natural gas peakers strictly to emergencies
“The role of peaker plants is going to be moved increasingly to emergency situations, right? That you've got battery storage and lots of other technologies that are being used inside the Intermountain West. To be able to provide these sort of services. And so p…”
Shah: ACES is the first commercial hydrogen storage salt dome
“Yeah, so, I mean, I don't think there's ever been a salt dome repurposed for hydrogen in this way and so there's certainly been test facilities that have been built in the past, but to our knowledge, there's never been a commercial hydrogen storage salt dome, …”
Shah: ACES electrolyzers will initially pull grid power matched by RECs
“So for the first iteration they're just getting connected to the grid, and there's going to be a network of contracts and racks to make sure that it's a hundred percent clean energy.”
Shah: Continuous electrolyzer operation yields sub-$4/kg clean hydrogen
“When you think about using these kinds of electrolyzers and running them all the time you really can get below four dollars a kilogram for clean hydrogen, right? And so but that does require you to get affordable electricity, but also very high run times, righ…”
Shah: ACES salt cavern will provide roughly 150 gigawatt-hours of storage
“Yeah, about a 150 gigawatt hours or so of storage there.”
Shah: Liquefied hydrogen shipping costs are generally over $8 per kilogram
“So then you end up with you end up with, you know, liquefied hydrogen, you know, shipments, which generally is very hard to do at less than eight or so dollars a kilogram of hydrogen.”
Shah: Green ammonia is profitable today without any government subsidies
“Such that you know, I think green ammonia, you know, today is quite profitable without any subsidies at all even at today's cost of hydrogen, right?”
Shah: Announced hydrogen projects model power at $30 to $34 per MWh
“And remember, for a lot of the announced projects in the country, they're talking about 30 to 34 dollars a megawatt hour for the power, right? They're not talking about 12 dollars a megawatt hour for the power.”
Shah: Developers finding US sites with sub-$35/MWh power 90% of the year
“They are finding many, many, many locations across this country where you can average less than 35 dollars a megawatt hour for 90% plus of the hours of the year on the LMP.”
Shah: EV boom will starve grid storage of lithium-ion batteries
“A lot of lithium ion battery capacity is going to be unavailable to the grid capacity marketplace once autos are ramping up.”
Shah: Non-lithium battery chemistries will reach commercial scale within five years
“I think we're actually five years away from all of those technologies being available at scale to the marketplace.”
Shah: ACES secured investment-grade rating, unlike most single-B DOE LPO projects
“This project is really well structured. It was rated at investment grade for the loan, so it's actually really well structured. Many of our projects are triple C or single B in terms of its shadow credit rating”
Shah: Hydrogen and ammonia create massive option value for renewable power
“So I just think that people are so myopic in the way that they think about traditional solar and wind models, that they think that the price of this stuff is going to zero. But in fact, the option value has now just gone up substantially.”
