CO₂ Recovery With Fuel Cell Technology

Written by Tony Leo | Aug 16, 2023 2:04:48 PM

CO2 has an important role in the supply chain of many industries from carbonating beverages to processing food, producing dry ice, cooling, producing fertilizer, and treating water. Many businesses rely on CO2 to keep their operations running, but where does CO2 come from?

CO2 is a byproduct of chemical processes or combustion. The gas can be released naturally from activities like volcanic eruptions or from industrial activities like ethanol production (or from combustion of fuels specifically for CO2 production itself). Traditionally, businesses have relied on external suppliers to meet their CO2 needs. The commercial CO2 supply can be impacted when ethanol and ammonia plants lower production output or if natural reservoirs become depleted or contaminated. These supply shocks can impact the contractual agreements of CO2 providers, resulting in unfulfilled deliveries or price increases under force majeure clauses. This poses a significant risk to businesses that rely on CO2 for their operations.

Fuel cells can help businesses avoid this risk and enhance the sustainability of their operations with on-site co-production of CO2, heat, and power. The fuel cell reactions convert methane-based fuels into hydrogen, which is used to make power in the cells. The CO2 byproduct can then be captured, purified, and used by the business rather than being emitted into the atmosphere. Self-supplying CO2 with fuel cells can ensure consistent pricing, availability, and quality. CO2 captured from the fuel cell system is already clean because of the lack of combustion products and can be easily purified to ISBT beverage-grade CO2 standards. CO2 recovered from fuel cells can also be sold, sequestered, or used directly on-site.
