About the tracker

Advanced Cleantech Deployments

An open-access database tracking real-world deployments of advanced clean technologies — from direct air capture to advanced nuclear reactors.

Our mission

The energy transition requires not just mature renewables, but a second wave of harder-to-deploy technologies, including direct air capture, advanced nuclear, long-duration storage, and enhanced geothermal, to reach net zero. These projects are being built today, but they are scattered across developer websites, government databases, and regulatory filings, making it difficult to get a clear picture of where deployment actually stands.

This tracker exists to make that picture clearer. We aggregate publicly available data on individual projects, structure it consistently, and present it in a format accessible to researchers, investors, policymakers, and anyone following the clean energy transition.

We do not provide financial advice, and inclusion in the tracker is not an endorsement of any project or developer. Our only criterion for inclusion is that a project is real, identifiable, and deploying an advanced clean technology.

Technology focus

The tracker currently covers five technology buckets. These were chosen because they represent the frontier of climate technology deployment, areas where capital is being committed and projects are being built, but where the deployment picture is not yet well understood. View all technology overviews →

Direct Air Capture

Atmospheric CO₂ removal using solid sorbent or liquid solvent systems.

Point Source Capture

Carbon capture at industrial emissions sources such as power plants, cement, and steel facilities.

Next-Generation Geothermal

Next-generation geothermal including enhanced geothermal systems (EGS) and closed-loop designs.

Advanced Nuclear

Small modular reactors (SMRs), Generation IV designs, and other non-conventional reactor technologies.

Long-Duration Energy Storage

Storage technologies capable of discharging for 8+ hours, including iron-air batteries, compressed air, and thermal systems.

Methodology

Every project in the tracker is built from publicly available information. Here is how we find, verify, and maintain the data.

🔍

Project identification

We systematically scan developer announcements, government agency databases (DOE, NREL, EPA), regulatory filings, and trade press to identify projects deploying advanced cleantech. A project is included when there is meaningful public evidence of a real deployment, not a concept study or design exercise.

📰

Source review

Each data point is traced to a primary source: the developer's own press releases and website, official government grant announcements, utility filings, or wire-service press releases issued directly by the project team.

🗂️

Data structuring

Projects are categorised by technology bucket (Direct Air Capture, Geothermal, Nuclear, Point Source Capture, Energy Storage), development stage, capacity, and expected commercial operation date. Where a project has multiple build phases, phase-level data is captured separately.

🤖

AI-assisted enrichment

We use large language models to generate structured project descriptions and extract key metrics from lengthy source documents. All AI-generated content is reviewed against the cited sources before publication. The underlying sources are visible on every project page.

🔄

Ongoing maintenance

The tracker is updated continuously as new information becomes public. Each project page displays a last-updated date drawn from our database. If you notice an error or have better data, please contact us.

Limitations and caveats

Completeness. This tracker covers projects that have made enough public announcements to be identifiable. Early-stage projects under development agreement or subject to confidentiality requirements may not appear until more information becomes public.

Accuracy. Project data, particularly capacity, cost, and commercial operation dates, frequently changes as projects progress. We update records as new information is published, but there will always be a lag between real-world developments and what appears here. The last-updated date on each project page indicates when our data was most recently reviewed.

Geographic scope. The tracker has the broadest coverage in the United States, reflecting the availability of English-language public information. International coverage is expanding as the dataset grows.

No financial advice. Nothing on this site constitutes investment advice or a recommendation to invest in any project, technology, or company.
