What Is FOAK in Climate Tech? From Pilot to First Commercial Deployment

This guide defines FOAK and explains why the first commercial plant is a different decision. For the stage-by-stage comparison, read FOAK vs Pilot vs Demonstration vs NOAK: What Is the Difference?.

FOAK stands for first-of-a-kind. In climate technology it names a company's first commercial-scale deployment of a new technology or configuration, after laboratory, pilot and demonstration work. At FOAK the question moves from whether the technology works to whether one specific asset can be built, financed, operated and paid for.

What does FOAK mean in climate tech?

The boundary varies by sector and by project. A project can be first at a particular scale, first in a geography, first in a specific configuration, or the first commercial use of a technology that has already run elsewhere. Two companies can both call their next plant FOAK and mean quite different things. The useful question for any team is what is genuinely first in the project and what has already been proven.

Governments, funds and industrial buyers all watch who builds the first plant in a category, because the first plant sets the reference point for every plant after it. Its delivered cost becomes the number the next lender starts from. Its schedule becomes the benchmark for the next contractor, and its operating record becomes the evidence the next buyer asks to see.

For a founder, the definition matters less than what it implies. A FOAK project is where a company stops asking investors to believe in a technology and starts asking a wider group of institutions to commit to an asset. Those institutions include buyers, lenders, engineering contractors, host sites, insurers and public funders. Each one reads the project through its own mandate and its own exposure.

Why does the decision change at FOAK?

A pilot asks whether the technology can work under relevant conditions. A first commercial project has to answer a longer list. It has to show that the plant can be built at this site, delivered on schedule, integrated with the surrounding system and run to specification. It needs a buyer for the output on defined terms. It needs a clear view of who carries construction and performance risk, how the project is financed, and what happens when costs or timelines move.

Each of those questions has a different owner. The technical team can answer the first. Only a buyer can answer the second, and only a financier can say whether the risk allocation works for their capital. A company can leave a pilot with good data and still face a long road to its first plant. The IEA titled one of its commentaries Energy innovation has a commercialisation problem, and FOAK is where that problem arrives on a balance sheet.

The evidence a company holds changes status at this point too. Pilot data stays valuable, and its job shifts from destination to exhibit. Our piece on moving from pilot evidence to project evidence covers that shift.

Where FOAK sits in the scale-up sequence

Terminology differs by sector and funder, but most climate hardware follows a similar path. Laboratory and prototype work shows that a mechanism can work. A pilot shows that it can operate outside the lab at limited scale. A demonstration runs a larger integrated system in conditions closer to commercial use, often for longer periods, and sometimes produces material for customer qualification.

FOAK is the first commercial-scale project, with real counterparties, contracts and economics. J.P. Morgan's 2026 climate tech report places it in the same position, at the first commercial-scale facility between demonstration and repeated expansion. The projects that follow are sometimes called early-of-a-kind, when the design is repeating but costs and schedules still move quickly. Nth-of-a-kind, or NOAK, describes later deployments that can draw on a genuine reference class of built projects.

These stages are working categories. No legal or engineering standard fixes them, and commercial scale for a direct air capture plant has little in common with commercial scale for a fermentation facility or a thermal storage installation. The comparison in FOAK vs pilot vs demonstration vs NOAK sets out what each stage tries to prove and what each one leaves open.

1. 01Lab and prototypeThe mechanism can work.
2. 02PilotIt operates outside the lab at limited scale.
3. 03DemonstrationAn integrated system runs close to commercial conditions.
4. 04FOAKThe first commercial-scale project, with real contracts and economics.
5. 05NOAKLater plants draw on a reference class of built projects.

Labels vary by sector and funder. What each stage proves stays the same.

How large is the jump?

The financing scale can change before the company feels ready for it. MaRS opened Canada's first-of-a-kind lab in May 2026 for ventures preparing their first full commercial-scale deployments. It estimated that dozens of Canadian climate tech companies could be preparing projects in roughly the $50 million to $200 million range by 2028. A project of that size has left the logic of a venture round and still looks unfamiliar to infrastructure finance.

The US Department of Energy approaches the same transition through its Pathways to Commercial Liftoff reports. They pair technical readiness with market formation, demand, investment and deployment conditions. The shared lesson is that commercialisation is a system problem. A working technology is one input among several, and the others belong to people outside the company.

Two public first plants, Climeworks and Carbios

Direct air capture offers a clear public sequence. Climeworks launched Orca in Iceland, broke ground on Mammoth in June 2022 and later switched Mammoth on. Each plant was a first at its own scale, and each became the reference point the next design was measured against. For a buyer or financier, the useful information sits under the scale headline, in the operating data, the delivered cost and the lessons carried into the next design.

Carbios shows a different side of FOAK. The company has advanced commercial contracts, public support and financing for its Longlaville PET biorecycling plant in France, and it adjusted the plant's timeline in late 2024 while financing was completed. In August 2026 Carbios reported that several banking partners had received credit committee approval, and that its earlier financial close target would not be met. The case resists a simple success or failure reading. Different parts of a FOAK project move on different clocks, and the story has to show each clock honestly.

Why are FOAK projects hard to finance?

FOAK projects sit between capital models. A first commercial plant can be too capital-intensive for venture equity alone while still lacking the operating history, contracts and risk profile that conventional project lenders expect. Some of its uncertainties also have no commercial-scale reference class, which makes them hard to price. Waiting for someone else to go first can be a sensible choice for each individual financier, even when it leaves the market with no first plant at all.

A venture investor backs a company because they believe the team, technology and market can create value. A project financier evaluates one asset, its location, its builder, its buyer, its contracts, its cash flows and what happens if it underperforms. A company can therefore be fundable while its project is not yet financeable on the terms the team wants, and that gap opens at FOAK. The full argument, including the difference between risk and ambiguity, sits in why FOAK climate projects are hard to finance.

What changes in the story at FOAK

Earlier climate storytelling usually concentrates on the problem, the technical breakthrough, the pilot result and the size of the market. At FOAK the story widens into six connected cases, which we set out in the FOAK Story System.

Technology: what has been demonstrated and what has not.

Commercial: who needs the output and on what terms.

Project: site, integration, engineering and delivery.

Risk: what can be priced, transferred or mitigated, and what stays ambiguous.

Capital: which investors or lenders can hold which exposures.

Scale: what this first project proves for the next one.

The cases matter because different people read them. An offtaker reads the commercial case first, and a lender reads the signed offtake too, because it shows who will pay for the output. A lender also reads the risk and capital cases. An engineering contractor reads the project case, and a public funder reads the scale case for what the first plant does for the sector.

Which parts of the project are actually first?

A project can be novel in one dimension and familiar in several others. The core equipment may be new while the civil works and construction method are conventional. The process may be proven while the feedstock and site integration are new. The product may meet specification while no buyer has yet purchased it at this volume.

Financiers, buyers and partners can accept some novelty. They need a clear account of which elements have precedent and which do not. Presenting the whole project as one large innovation makes the risk look larger and harder to assess than it is. Pretending nothing is new fails in the other direction, because a project with nothing new would not be first-of-a-kind. Breaking it apart shows where adjacent evidence applies, where contracts move risk to a party better placed to hold it, and where genuine ambiguity remains. Industrial biotechnology adds its own layer, because scaling a fermentation process changes the biology as well as the engineering.

What should the first plant prove for the second?

The first commercial project is an asset and an evidence base at the same time. The data it produces sets the terms of the second project, so the team should decide before construction what project one needs to record. For most climate hardware the list looks like this.

• Delivered capital cost against the estimate, line by line
• Construction schedule and the causes of any delay
• Availability, reliability and maintenance needs in operation
• Product specification and customer acceptance
• Integration issues with the host site and utilities
• Risk events and how contracts and insurance responded
• The capital structure that was actually usable

A project that records these deliberately changes the story of the next deployment. That record is what turns a first plant into a repeatable programme, and it is the start of the reference class that later projects will be financed against.

How to test your own FOAK case

Start by writing one page on what your next project is first at. Keep it short enough that a lender, a buyer and an engineer could each read it in five minutes and agree on the facts. Name the scale, the configuration, the geography and the market, and mark each one as first or precedented. Then list the evidence you already hold against each of the six cases, and be strict about status. A signed offtake, a letter of intent and a customer conversation carry different weight, and a reader who finds them blended will discount all three.

Then find the weakest case. Credible FOAK communication makes uncertainty legible. It separates what is proven, what is estimated, what transfers from adjacent evidence, what is covered by contract and what remains unresolved. No page can guarantee a yes. A clear one gives a decision-maker a case they can assess. Share the page with one friendly financier and one prospective buyer before any deck is designed. Their questions will show which case they read first and where the evidence runs thin.
