The U.S. nuclear sector just received another strong signal of federal backing.
On February 21, the U.S. Department of Energy (DOE) finalized a $303 million Technology Investment Agreement with Kairos Power to advance its Hermes demonstration reactor in Oak Ridge, Tennessee. The deal supports the company’s selection under the Advanced Reactor Demonstration Program (ARDP), first announced in December 2020.
But this is not a traditional federal grant. Instead, DOE structured the agreement as a performance-based, fixed-price milestone contract. Kairos will only receive payments once it achieves clearly defined technical milestones.
This funding model was previously used by the Department of Defense and NASA’s Commercial Orbital Transportation Services (COTS) program. It aims to accelerate innovation while protecting public funds. Now, DOE is applying that same discipline to advanced nuclear technology.
Hermes: The First Gen IV Reactor Approved in Decades
At the center of the agreement is Hermes — a low-power demonstration reactor based on Kairos Power’s fluoride salt-cooled high-temperature reactor (KP-FHR) design.
In December 2023, the U.S. Nuclear Regulatory Commission (NRC) granted Hermes a construction permit. That approval marked a historic milestone. Hermes became the first non-light-water reactor approved for construction in the United States in more than 50 years. It is also the first Generation IV reactor cleared for building.
The reactor is expected to be operational in 2027. While it will not generate commercial electricity, it serves a critical role. Hermes will demonstrate Kairos Power’s ability to safely deliver low-cost nuclear heat and operate a fully integrated advanced nuclear system.
Its design combines two established technologies that originated in Oak Ridge: TRISO-coated particle fuel and Flibe molten fluoride salt coolant. Together, these systems enhance safety and simplify operations.
The molten salt coolant improves heat transfer and stability, while TRISO fuel provides strong containment of radioactive materials. The result is a reactor design that emphasizes inherent safety without relying on overly complex backup systems.
Significantly, Hermes represents Kairos Power’s first nuclear build, and it acts as a stepping stone toward commercial deployment.
Mike Laufer, Kairos Power co-founder and CEO, said:
“With the use of fixed-price milestone payments, this innovative contract provides real benefits to both Kairos Power and DOE to ensure the successful completion of the Hermes reactor. It allows us to remain focused on achieving the most important goals of the project while retaining agility and flexibility to move quickly as we learn key lessons through our iterative development approach.”
Risk Reduction and Private Capital Alignment
The DOE’s investment complements significant private funding already committed by Kairos Power. Since its ARDP selection, the company has built extensive testing facilities and manufacturing infrastructure to support its Engineering Test Unit series. It has also advanced its fuel development and molten salt coolant systems.
Unlike traditional large-scale nuclear projects that often suffer cost overruns, Kairos is pursuing an iterative development pathway. This approach allows the company to test, refine, and improve reactor components before full commercial rollout.
Fuel manufacturing plays a key role in that strategy. Kairos Power is working in partnership with Los Alamos National Laboratory to produce fuel for Hermes. Through its Low Enriched Fuel Fabrication Facility (LEFFF), the company aims to control quality, reduce delays, and manage costs more effectively.
Vertical integration is central to its business model. By managing more of the supply chain internally, Kairos hopes to deliver greater cost certainty for future commercial reactors — an area where traditional nuclear projects have struggled.
Key Features
Nuclear’s Return to the Energy Spotlight
The Hermes agreement comes at a time when nuclear energy is regaining political and investor attention.
Federal policy has shifted in favor of accelerating the development of next-generation reactors. In 2025, the U.S. administration introduced measures to shorten licensing timelines and rebuild domestic nuclear fuel supply chains. The Department of Energy has articulated an ambitious goal: expand U.S. nuclear capacity from roughly 100 gigawatts in 2024 to 400 gigawatts by 2050.
Programs such as the Energy Dominance Financing initiative aim to provide additional support for nuclear infrastructure. Once built, reactors can operate for up to 80 years, making them long-term strategic assets.
At the same time, electricity demand is rising. According to the International Energy Agency (IEA), U.S. electricity demand grew 2.8% in 2024 and another 2.1% in 2025. The country is projected to add more than 420 terawatt-hours of new demand over the next five years.
Data centers are driving much of that growth. The rapid expansion of artificial intelligence and cloud computing infrastructure could account for nearly half of total demand growth through 2030.
This dynamic is reshaping energy investment decisions. Technology companies require reliable, always-on power. However, they must also meet emissions reduction targets. Nuclear energy provides steady, low-carbon electricity, making it increasingly attractive for both policymakers and corporate buyers.
Small Reactors, Big Strategic Impact
Small modular and advanced reactors are the keys to this renewed momentum. Compared to traditional gigawatt-scale plants, smaller reactors offer shorter construction timelines and lower upfront capital requirements. Developers can deploy them incrementally, reducing financial risk and improving flexibility.
Hermes, although it is a demonstration project, it represents a critical validation step. If successful, it could pave the way for commercial-scale KP-FHR reactors that supply industrial heat and electricity at competitive costs.
Dr. Kathryn Huff, Assistant Secretary, Office of Nuclear Energy, made an important statement, noting:
“The Hermes reactor is an important step toward realizing advanced nuclear energy’s role in ushering forward the nation’s clean energy transition. Partnerships like this one play a significant role in making advanced nuclear technology commercially competitive.”
For investors, this shift signals opportunity. Supportive government policy, rising electricity demand, AI-driven load growth, and decarbonization commitments are converging. Nuclear power, once viewed as a legacy industry, is re-emerging as a strategic solution.
A Measured Step Toward a Nuclear Renaissance
The DOE-Kairos agreement does not guarantee success. Advanced reactor development remains technically complex and capital-intensive. However, the deal’s structure reflects lessons learned from past nuclear projects.
By tying federal funding to performance milestones, DOE is promoting accountability. By combining public and private capital, the government is reducing financial risk while accelerating innovation.
Hermes now stands as one of the most closely watched advanced reactor projects in the United States. If Kairos delivers on schedule, the project could mark a turning point. Not just for one company but for the broader U.S. nuclear renaissance that policymakers increasingly envision.
In a world of rising electricity demand and tightening climate targets, advanced nuclear energy is inevitably essential. And with Hermes moving forward, it is becoming tangible infrastructure.

Most businesses that decide to act on their net-zero targets reach the same point of friction. Buying carbon credits has meant tracking down brokers, sitting through sales calls, and requesting a quote just to learn a price, sometimes with limited proof of what you are buying.
The earnings calls that quietly reframed climate from sustainability question to operating risk.
Three earnings calls in the last 18 months tell the story without any help from a press release.
Hershey, May 2024: cocoa price exposure compresses margin, and the company attributes part of the cost shock to West African weather. Olam, July 2024: coffee climate exposure quantified in the annual report. JBS, January 2025: supply chain climate disclosures expanded materially in response to investor pressure and regulatory expectation. None of these companies issued the announcement as climate news. They issued it as financial news. The climate-linked supply chain risk did not arrive with a sustainability framing; it arrived as a P&L line.
You are probably reading this article because you suspect the same thing is happening to your business. This piece walks through what is showing up on which earnings calls, how procurement and finance leaders are quantifying the exposure, and what serious corporates are doing about it before the regulator asks.
Where climate risk has already appeared in earnings
The pattern is consistent across resource-intensive sectors. A weather event compresses supply, the price spikes, the cost flows through the income statement, and the analyst on the call asks whether the event is anomalous or structural. Increasingly, the honest answer is the second one.
Cocoa is the cleanest example. The 2023 to 2024 West African harvest fell sharply on the back of erratic rainfall and disease. Cocoa futures more than tripled. Companies with concentrated West African sourcing absorbed the cost; companies with diversified sourcing absorbed less. The exposure was not climate as ESG topic. It was climate as cost of goods.
Coffee follows the same pattern. Brazilian and Vietnamese harvests have moved on weather more sharply across the last several seasons. Roasters with long-tenor supplier relationships and origin diversification have managed the volatility; roasters with spot-market exposure have not. Wheat, sugar, palm oil, beef: the same dynamic in different commodities, a pattern the IPCC AR6 Working Group II report projects will intensify across agricultural systems through mid-century.
What this means: climate risk is no longer a footnote in the 10-K. It is a line item the CFO has to explain on the call.
The three commodity exposures that hit margin first
For most companies with material Scope 3 exposure, three exposures dominate the near-term P&L risk.
- Concentrated single-origin sourcing in a climate-vulnerable region. If your tier-one supply for any material commodity sits in one geography, you have a concentration risk that climate amplifies. Diversification across origins is the obvious hedge, but it takes years to build and requires relationships you cannot acquire by tender.
- Supplier financial fragility under climate stress. Smallholder farmers, who supply a large share of the global cocoa, coffee, and palm oil market, do not carry the balance sheets to absorb yield shocks. When yields collapse, they exit. When they exit, your supply base shrinks, and the surviving suppliers raise prices. The risk is structural, not cyclical.
- Logistics and storage exposure to extreme weather. Hurricane disruptions to Gulf shipping, drought-driven Panama Canal restrictions, flooding in European inland waterways: each of these has moved input costs in the last three years, a pattern documented in Munich Re’s natural catastrophe data. The exposure shows up as a one-quarter event in the financial press but accumulates over time on the cost line.
TCFD and ISSB disclosure changes
The disclosure architecture has now caught up with the risk. The Task Force on Climate-related Financial Disclosures, whose recommendations are now embedded in the ISSB’s IFRS S2 climate standard, requires companies to disclose climate-related risks across physical and transition categories, with quantification where possible.
For physical risk specifically (the climate-linked supply chain risk you are reading about), the disclosure must address both acute exposures (extreme weather events) and chronic exposures (gradual changes in temperature, precipitation, and growing seasons). The disclosure must address the time horizon over which the risk is material, the parts of the value chain exposed, and the financial impact under different scenarios.
The CSRD imposes similar requirements under European law, with double materiality (both financial and impact materiality) embedded in the assessment. The practical effect: your auditors and your investor relations team now need a defensible answer to the climate-linked supply chain risk question, and the answer needs to be quantified.
What procurement and finance can do now
Three actions matter near-term.
Map your exposure. Most companies do not have a clear view of which tier-one and tier-two suppliers sit in which climate-vulnerable geographies. Without the map, you cannot quantify the risk, and without the quantification, you cannot disclose it credibly. The map is the foundation, and World Resources Institute climate risk research provides useful public tooling to start.
Diversify and deepen, in that order. Diversification across origins reduces concentration risk, but the deeper move is to invest in the resilience of the suppliers you already have. Regenerative practices, agroforestry, soil health interventions: these reduce yield volatility under climate stress and protect your input cost trajectory.
Embed the climate spend inside procurement, not outside it. Treating climate risk as a sustainability cost line subordinates it to the ESG budget. Treating it as a procurement and resilience investment puts it in the budget that matters, which is the cost-of-goods budget that the CFO defends quarterly.
Nature-based supply chain investments are the asset class designed for exactly this purpose. They sit inside the value chain, they reduce climate-linked supply risk, they generate verifiable Scope 3 reductions, and they produce the documentation an auditor and a regulator can both test.
If you are quantifying climate-linked supply chain risk in advance of the next earnings cycle or the next disclosure period, the carbon and sustainability experts at Carbon Credit Capital can help you map your exposure and structure a Dual-Value Model response that addresses reduction, resilience, and disclosure-readiness in a single program. Schedule a consultation.
More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.
