🌎 Fervo and X-energy's IPOs draw clean firm's cost curve #295

Happy Monday!

We went through Fervo and X-energy's S-1 filings so you don't have to. The numbers are the clearest window yet into what clean firm actually costs.

In deals, $140m for wave power, $60m for ultra-fast charging, and $40m for EV battery repurposing.

In other news, regulatory tailwinds for microreactors, Blue Energy gas-to-nuclear hits new milestone, and European batterymaker Morrow goes out of business.

IPO season featuring Fervo and X-Energy

It’s a big moment for our sector. Two darlings are making their debut: advanced nuclear reactor company X-energy has officially IPOed, and enhanced geothermal systems developer Fervo Energy has filed to. 

Luckily for us, these IPO and SPAC filings bring more disclosure on costs, timelines, and project economics. So we took a peek at the S-1s, and they give us the clearest window yet into what clean firm actually costs to build.

What happened

Why it matters

Fervo and Google's deal stands out. Google is the first to lock down the first real shot at scalable clean firm in a while. Fervo has better economics, earlier revenue, and cheaper capital than any comparable startup, and Google wants to get a piece of that pie. The GFA signed in March gives Google right of first refusal over part of Fervo's uncontracted pipeline and downside cost protections. Given Fervo is the only developer likely to bring hundreds of megawatts online in the coming years, it's a solid bet.

Fervo doesn't need to hit its cost targets to build a big business. Even at $5,000/kW — short of the $3,000/kW goal — its LCOE would be around $100/MWh, a price point with massive demand. With low operating losses, project finance capability, and $7.2bn in contracted revenue not far off, Fervo is in great shape.

X-energy, meanwhile, is a bet on nuclear licensing — notoriously tough, lengthy, and expensive. The company is burning cash before the hard part starts: a $390m net loss before FOAK construction has begun, a construction licence not expected until 2027, and an analogue project that took 11 years to reach commercial operation. It will need billions more in equity before it generates meaningful power revenue.

Key takeaways

• These are the first real price signals the sector has ever had. Fervo is the first EGS company to go public, and it has set the industry’s benchmarks: $7,000/kW FOAK OCC. Meanwhile, X-energy’s filings reveal $4.75–5.75bn for a 320MW SMR, even though those estimates are from 2023, so they could be even higher today. Still, X-energy was the largest nuclear IPO in history with a 27% pop. Whatever comes next gets benchmarked against these numbers and that's a big deal for every developer still in private markets.
• X-energy is betting on tech, Fervo on resources. Unlike most clean energy startups, Fervo's competitive advantage isn't a patent portfolio or proprietary technology. Its best moat is the 596,000 acres of high-quality geothermal resource in the western US. That's a pattern that oil and gas has well-established. Fervo’s developer business model could pay off in the near term, but it’s ultimately bounded by how much it can drill. X-Energy’s capital requirements are substantially larger, its timeline extends into the early 2030s at best, and its DOE funding is not guaranteed, but if it executes, the licensing model allows for rapid scale. Each deployment could generate technology fees, engineering services revenue, and upfront recurring revenue.
• Hyperscalers are moving from offtaker to architect. Google structured an agreement that brings new restrictions on who Fervo can work with. Amazon and X-energy also have an interesting deal: Amazon is simultaneously the anchor customer, major shareholder, and strategic partner with an option on 5GW of capacity. For the data center end use case that both are targeting, SMRs have two major advantages over EGS; they’ll likely have higher capacity factors and aren’t restricted to remote areas of the western US. But in an industry that mostly cares about speed right now, Fervo has the edge.

Reading list

☢️ The NRC proposed Part 57, a new regulatory framework that would actually make microreactors viable. It removes barriers around shipping fuel loaded reactors, eases site security requirements, and introduces fleet licensing instead of individual approvals. [Link, Link]

This is the unlock the microreactor space has been waiting for and Radiant looks like the biggest winner here. Pair this with DIU's recent Advanced Nuclear Power for Installations selections and you have an emerging procurement + regulatory tailwind for the category.

☢️ Blue Energy announced GE Hitachi as its nuclear partner for its 2.5GW Texas FOAK, with 1GW of gas power potentially online by 2030 and nuclear coming in 2032 at the earliest. [Link]

GE Hitachi is arguably the best partner Blue Energy could have landed, aligned with its heavy deployment and financial risk mitigation focus. The gas bridge to nuclear sequencing also leapfrogs many advanced nuclear FOAKs that are still pre-construction. 

🔋 Morrow files for bankruptcy, the latest European battery maker that can't compete with China on price. [Link]

European battery startups are stuck between two impossible options: compete on price against vertically integrated Chinese giants (CATL, BYD have cost advantages at every stage of production), or differentiate on sustainability/supply chain security and hope premium buyers show up. So far, the premium and state-level support haven't been enough.

💨 Fertiberia signed a deal to supply PepsiCo with up to 150,000 tonnes of green hydrogen-based fertilizer annually. [Link]

It’s a significant offtake agreement for green hydrogen, which has been struggling. But big F&B investments could help unlock this use case for hydrogen, and the scale here alone is meaningful for one of the toughest hydrogen offtake categories. 

📊 SEC is scrapping climate risk reporting requirements, but also moving away from quarterly reporting. [Link]

Killing the public company climate disclosure rule is the headline - but Republicans have long been fighting against this rule. Meanwhile, the shift away from quarterly reporting could have potential benefits, as quarterly cycles are capital intensive and punish long-payback climate investments. Less short-term focus could benefit to long-term climate projects.

⛽ Gulf state sovereign wealth funds may be exploring war related force majeure to exit binding climate finance commitments. With ~40% of global sovereign wealth coming out of the Gulf, this could put trillions in pledged climate project finance at risk. [Link]

The projects in the region mostly include data centers, alt fuels, SAF, and CCS.  Force majeure clauses don't apply selectively, but if possible, the ones most likely to be abandoned are the ones whose economics have soured.

⛏️ USGS finds eastern US hard rock lithium reserves could replace imports for "a century or more." [Link]

Permitting, infrastructure, and processing capacity timelines for developing these resources mean minimal short-term impact on critical mineral security or domestic battery supply chains.

🚢 US mounts another new bid to block international shipping carbon tax. [Link]

🌎 Ted Turner: a media mogul who tried to repair the land. A profile of the largest individual landowner in the US and his decades-long bet on bison, conservation, and ecological restoration. [Link]

⚡ New IRENA report: solar + BESS is now eating clean firm power's lunch on economics. [Link]

🛢 Meanwhile, Fermi's gas-to-nuclear strategy unraveled, CEO ousted after stock slid. [Link]

💡 Hannah Ritchie's latest take on AI electricity demand, with a more measured read of the data than most. [Link]

🚗 EVs in Europe going gangbusters, with sales accelerating despite the broader auto market crunch.
