At Pace Ventures, we’re thrilled to invest in Turnover Labs, a company revolutionizing point-source carbon capture and utilization. Their innovative electrolyzer technology transforms CO₂ emissions into valuable chemicals on-site, offering heavy industries a commercially viable path to decarbonization.

The Market Opportunity

We believe that for climate technologies to scale, they must first create economic value and then address environmental challenges. While Direct Air Capture (DAC) and other carbon capture technologies are essential, we identified a significant gap in point-source carbon capture solutions, as it remains an added cost to the emitter.

Today, most point-source capture systems are limited to separating CO₂ for storage or sale as a gas in industry. We envision a future where chemical processes are decarbonized, and point-source carbon capture provides economically viable solutions for emitters beyond reducing emissions.

The petrochemical industry, a major polluter, is actively seeking solutions to cut greenhouse gas (GHG) emissions. This underscores the need for retrofittable, cost-effective solutions. Turnover Labs addresses this need by providing a turnkey approach that converts CO₂ into useful chemicals at the source, eliminating the need for transportation of gases, and making the process both more sustainable and scalable.

The Turnover Labs Solution

Turnover Labs, founded by Marissa Beatty, is focused on making carbon capture not only feasible but profitable. They’ve developed an electrolyzer capable of withstanding harsh environments, making it far more durable and efficient in CO₂ reduction processes.

This technology eliminates the need for costly pre-processing of industrial emissions, reducing both CAPEX and OPEX for the emitter. Through a one-step process, the electrolyzer converts CO₂ from untreated waste gases directly into carbon monoxide (CO), a valuable feedstock for producing syngas or other downstream chemicals.

The result is a more robust system that can operate for longer periods without maintenance and with lower upfront costs. To put this in numbers, Turnover’s approach has yielded electrolyzers that have a > 500% increase in their lifetime and a 40% improvement in energy.

The Founder

Dr. Marissa Beatty, Turnover Labs’ founder, Forbes 30 under 30 Energy 2024, brings a unique blend of passion, creativity, and pragmatism to her work. With a PhD in Chemical Engineering focusing on Electrochemistry, she has spent her career focused on making electrochemical systems more durable and adaptable to harsh industrial conditions. Her research originally focused on seawater-to-hydrogen conversion, a project that required her to develop resilient systems capable of handling fluctuating environments — skills she has now applied to carbon capture.

When we visited her lab in Brooklyn, Marissa walked us through the whole technology right at the fumehood, explaining everything with such clarity and passion — we were so impressed! Her deep understanding of the science, coupled with her ability to consistently overdeliver on product milestones to date, really struck a chord with us. We can see why Forbes wanted to do an article on her journey.

Exciting Next Steps

Turnover Labs is at a pivotal stage, conducting lab-based trials with real industrial emissions samples. This marks the beginning of their journey toward an on-site pilot with a major industrial customer, and we are excited to support them as they scale their solution.

Our co-investors

We’re proud to be joined in this investment by other mission-aligned partners like GC Ventures, Collab’s Shared Future Fund, Gigascale Capital, Impact Science Ventures, and Sandy Spring Climate Partners, as we support Turnover Labs in making carbon capture a source of value, not just a cost, for heavy emitters.
