In this episode of Catalyst, host Shayle Kann and carbon expert Dr. Julio Friedmann examine the technical, economic, and logistical landscape of carbon management, analyzing how captured carbon dioxide can be permanently sequestered in deep geological formations or converted into construction materials, e-fuels, and advanced nanomaterials.
How this conversation actually went
Every chapter scored 0–10 on four independent dynamics. Hover any point for the reasoning behind the score. Shayle holds 27.1% of the talking time here. How this is scored →
Shayle as informed peer 4.6 Guest teaching 2.6 Guest disagreement 0.1 Shayle pushing back 1.0
speaking balance: gold is Shayle, purple is the guest (3 minute bins)
Sharpest disagreement ▶ 20:39 Guest dismisses theoretical thermodynamic optimization in executive decision-making
Julio Friedmann rejects the premise of seeking purely thermodynamic or economic optimums, pointing out that real-world CEOs and policymakers operate under entirely different supply chain and legal incentives.
Hardest push from Shayle ▶ 26:59 Host challenges assumptions on declining electricity costsShayle Kann interrupts the guest's optimistic trajectory on cheaper renewable inputs to emphasize that delivered electricity costs are moving in the opposite direction.
Biggest teaching moment ▶ 23:14 Guest details mandatory CORSIA aviation compliance deadlinesJulio Friedmann educates the host on the imminent 2027 UN ICAO CORSIA mandates, showing that global sustainable aviation fuel announcements fall far short of binding regulatory requirements.
Shayle holds their own ▶ 40:37 Host demonstrates technical depth on grid reconductoringShayle Kann immediately builds upon the guest's mention of advanced graphene materials to detail how conductive carbon composites could replace copper wiring in power lines.

Statements from this episode (18)
Friedmann: US CO2 pipelines are largely dedicated to enhanced oil recovery
“The 5000 miles of CO two pipelines in the United States are largely dedicated to that.”
Friedmann: 47 facilities globally capture 60 million tons of CO2 annually
“So we have something on the order of 47 facilities around the world that operating today that capture CO₂ and keep it out of the air and oceans for climate. Broadly, that's about sixty million tons a year.”
Friedmann: Shipping CO2 costs ~$18/ton by truck versus ~$2/ton by pipeline
“So it costs something like 18 bucks a ton or something like that to ship things by truck, where it might cost two bucks a ton to ship it by pipeline, right?”
Friedmann: Only a fraction of captured CO2 will be recycled into products
“To turn CO₂ into stuff usually takes energy or money. And so, in the same way we only recycle a fraction of our produced goods of any kind, whether it's glass or aluminum or paper or whatever, we also will only recycle a fraction of the CO₂.”
Friedmann: IPCC models show 90% of captured CO2 must go underground
“Out of the, say, six gigatons that the IPCC believes we're going to need to do, five and a half gigatons of that are going to be storage. It's something like 90%.”
Friedmann: Oil and gas geology has 10 to 20 trillion tons of CO2 storage capacity
“We have something like 10 to 20 trillion tons of storage capacity in those kinds of rocks.”
Friedmann: CO2-to-concrete is an exothermic, gigaton-scale market
“So turning CO two into concrete is a gigaton market, and it's not nuts. It actually releases energy.”
Friedmann: Hundreds of companies convert CO2 into building materials
“Now there's hundreds of companies that turn CO₂ into those kinds of products.”
Friedmann: EU Law Mandates 0.7% E-Fuels for Aviation by 2030
“0.7% of the fuels in Europe in 2030 are gonna be e-fuels for jets by law.”
Friedmann: Announced SAF plants cannot meet the 2027 global airline mandate
“If every Sustainable aviation fuel plant that had been announced were to be built, there would not be enough fuel for the twenty-twenty-seven target. Period.”
Kann predicts delivered electricity costs will rise for the foreseeable future
“The delivered cost of electricity is, The trajectory of it is the opposite direction, and I think it's going to be the opposite direction for a while.”
Friedmann: Methanol will become a major fuel for decarbonizing maritime shipping
“And the reason why is because methanol is going to be an important maritime fuel. About two, two and a half percent of global emissions are shipping stuff around the world with boats. And it turns out that they need a clean fuel too. As we've talked about befo…”
Friedmann: SABIC in Saudi Arabia already recycles CO2 into urea fertilizer
“One of them is urea, which is a massive fertilizer market today. That is super cheap and easy to do, and in fact, there's a couple of big plants around the world that do that today. In Saudi Arabia, for example, SABIC, the chemical company there, has been taki…”
Friedmann: Advanced carbon materials like graphene sell for $100k per ton
“If you can actually turn CO two into those materials, they're hard to make, but boy, are they valuable. They're like a 100,000 dollars a ton.”
Friedmann: Conductive carbon structures from CO2 possible in 15-20 years
“But these sort of, you know, superconducting carbon structures are a thing you could do, If not now, maybe in 15 years, maybe in 20 years.”
Friedmann: Tallgrass is repurposing a gas pipeline to transport Nebraska CO2 to Colorado
“One of them is, there was announcement just a couple of days ago, a portion of the summit pipeline, a company called Tallgrass, is going to capture CO₂ in Nebraska and store it in Colorado. They are repurposing an existing natural gas pipeline to do that.”
Friedmann: Community benefit agreements will become the template for CO2 pipeline approval
“I expect we're going to be seeing more of these kinds of things. That's not yes in every community, but it does mean that there will be some communities that opt in because they get the benefits themselves. So watch this space. This is no panacea or done deal,…”
Friedmann: German pipeline opposition forces CO2 transport onto Rhine river barges
“We're seeing that happening right now in Europe, where basically, instead of doing pipelines, they're doing barges. They're putting CO₂ on boats and shipping it down the Rhine, and the reason why is because they can't get a pipeline through Germany. Like, Germ…”
