Working Student Electrochemistry / CO₂… at Greenlyte… · Essen

Let’s build the fossil-free future

Are you ready to save the planet?

At Greenlyte, we are reshaping the global fuel economy with our novel, IP-protected, direct air capture to fuels technology, which shows superior economic potential compared to existing approaches, even reaching fossil prices. Backed by leading European VCs and with commercial agreement from Lufthansa and MB Energy, we are deploying our first commercial facilities to prove commercial viability in the next 12 months.

How you'll contribute

You join our CO₂ desorption team, which scales up an electrolyzer that releases captured CO₂ and explores how to turn that CO₂ into valuable products. Within a clearly scoped area, you work on electrode development and operate one of our electrochemical test stands.

• Fabricate, characterize, and iterate on electrodes and catalyst layers for our desorption electrolyzer, aiming for efficient CO₂ utilization.
• Operate and maintain one of our electrochemical test stands, including cell assembly, setup, and routine testing.
• Test electrode materials and cell configurations for converting captured CO₂ into valuable products.
• Ideate and run electrochemical tests together with the desorption research team.
• Prepare samples for chemical, mechanical, and electrochemical analysis.
• Analyze experimental data and summarize key findings so the team can decide on next steps.
• Keep the lab safe and organized, and support day-to-day laboratory operations.

Your first 12 months in the role

You start with guidance and a clear scope, and you take on more ownership as you grow into the work.

Month 1–3

• Get to know the team, our culture, and the fundamentals of our technology and lab setup.
• Learn lab safety standards, documentation practices, and core analytical techniques.
• Learn to operate the test stand safely and assist with cell assembly and electrolyzer testing.
• Start preparing electrodes and run electrochemical tests under supervision.

Month 4–6

• Run the test stand and standard electrochemical test protocols independently, and analyze the results.
• Fabricate electrodes from established recipes and compare their performance.
• Keep detailed experiment logs and help write reports for internal knowledge sharing.
• Support data processing, improve existing lab documentation, and begin refining procedures and basic troubleshooting.

Month 7–12

• Take ownership of one technical workstream, for example electrode and catalyst layer development, material screening, or CO₂ utilization performance.
• Contribute to hypothesis-driven experiment design and structured analysis of results.
• Collaborate with other teams, such as modeling, systems, and process engineering.
• Optionally, initiate and scope a thesis project aligned with your contributions.

About you
