Understanding the critical role of CO₂ sensors in carbon capture – interview with an operational DAC project

Octavia Carbon plant site in Kenya
Carbon capture
Two sessions to choose from

Welcome to the premiere episode of "Measurement Matters", Vaisala's new customer stories series.  You can't manage what you don't monitor, and in this series, we explore what that means in real world industrial applications. First up: carbon capture. 

Join us for an exclusive 30 minute conversation with Octavia Carbon, the Global South's first Direct Air Capture company, as they share how they overcame one of the most demanding measurement challenges in carbon capture: accurately monitoring CO₂ concentrations from ambient air (~430 ppm) all the way to 99.99% captured CO₂.

During this interview, you'll discover how Octavia Carbon's Process Optimization Lead evaluated multiple sensor technologies before finding the measurement solution that delivered the accuracy, stability, and reliability their scalable DAC process demanded, without constant recalibration.

What you'll learn:

  • Why measurement accuracy across extreme concentration ranges is critical for DAC process control and optimization
  • How the right CO₂ sensors eliminate costly recalibration cycles, save time and labor, and enable real time process decisions
  • The direct impact of sensor performance on sorbent efficiency, energy consumption, and overall process economics
  • How accurate, stable CO₂ measurements build confidence and credibility in carbon credit verification and third-party accreditation
  • Real world insights and practical advice from an operational DAC facility powered by renewable geothermal energy

Who's the webinar for:

  • Carbon capture operators and DAC developers
  • Climate tech startups scaling carbon removal technology
  • Engineering firms and system integrators designing carbon capture plants
  • Carbon credit and verification professionals
  • Renewable energy companies integrating carbon capture processes

If you can't watch the live session, go ahead and register anyway as we will later share the recording with you!
