COMPANY
Planeteers was founded in Hamburg with a simple idea – to bring science and engineering together for measurable climate impact. Rooted in research at the University of Hamburg, the company grew from an early prototype built in a small garage in Hamburg-Eimsbuettel into a focused effort to translate proven geochemistry into practical climate technology.

Planeteers was founded by engineers, scientists and entrepreneurs in Hamburg in December 2022 – combining industry experience, ocean science, and entrepreneurship.
Guided by our purpose to turn the tide for a livable future, we develop science-based technologies that remove CO₂ where it matters most: directly at emission sources and within the ocean’s natural systems. We keep the emphasis on what can be measured and verified – pairing careful engineering with transparent monitoring.
What started as an experiment has grown into a mission-driven company building scalable, verifiable solutions for permanent carbon removal. We aim to advance a livable future for all – by turning rigorous science into reliable operations — project by project, site by site.



We envision a world where carbon removal is an integral part of global infrastructure — operating seamlessly across industries, cities, and coastlines.
By turning proven science into scalable solutions, we aim to make CO₂ removal as routine and reliable as clean water or renewable energy.
Our vision is to be a key lever for a livable planet — advancing a future where technology, integrity, and measurable impact align to restore balance to Earth’s systems. Together, we turn the tide from vision to action — building the foundation for a balanced, livable planet.
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 honors validate our mission to turn rigorous science into scalable, measurable CO, removal – with integrity, transparency, and real-world implementation at the core.


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.
