We are Planeteers: Engineers for the planet

Planeteers is a strong team of passionate people driving change. We are scientists, engineers, and problem-solvers that are brave enough to innovate and create solutions that work outside of the lab to combat the climate crisis.

Planeteers developed the first all-in-one carbon capture and storage solution for industry ready to scale. We take inspiration from nature, rely on science for direction, and use technology to scale what works to create real-world impact.

Our vision & mission

Planeteers‘ vision is to be a key lever for a planet worth living on by growing a thriving company that delivers innovative solutions for all of us.

Our mission is to remove CO₂ where it matters most, from global industries to regional emitters. We build technology that can scale, with the goal of removing CO₂ on gigaton scale safely and permanently at the most significant sources.

R&D

„Planeteers’ solution closes a technological gap for capturing and storing CO2. As a municipal wastewater operator, it opens new revenue streams from negative emissions for our existing infrastructure, while simultaneously preparing us for future decarbonization regulation.“

Julia W. (Planning & Construction Lead, Wastewater Treatment)

„Planeteers’ approach stands out for its ability to integrate carbon capture and storage into existing industrial water streams, unlocking a cost-efficient and scalable pathway for durable CO2 removal. This type of infrastructure-enabled deployment model is critical for bringing high-quality carbon removal to gigaton scale.“

Frauke K. (Head of Science, Frontier)

„Planeteers’ end-to-end approach to decarbonization closes a technological gap for industrial plants. Especially for us as a lime producer, it opens up new opportunities to integrate this CCS solution into our existing facility, permanently remove CO2 economically, and even put our own waste materials from lime production to use.“

Arnt S. (Managing Director, Lime Producer)

Award-winning impact

Our work has been recognized with two of Germany’s most respected awards for entrepreneurship and sustainability:

The Hamburg Founder Award 2024 (Hamburger Gründerpreis 2024) and the German Sustainability Award 2025 (Deutscher Nachhaltigkeitspreis 2025).

These honours validate our mission to drive rigorous science into scalable, measurable CO₂ removal – with integrity, transparency, and real-world implementation at the core.

In addition, we have also been recognized by the European Innovation Council for our disruptive, breakthrough technology.

Partner with Planeteers to make carbon removal part of your operations. Our technology integrates with existing industrial and municipal systems, enabling measurable, permanent climate impact.
