Caravel Bio Innovates Carbon Capture Technology

Caravel Bio, a forward-thinking company specializing in protein engineering, is making notable strides in carbon capture technology. By harnessing innovative biocatalyst developments, the company aims to provide more efficient and cost-effective solutions to this pressing environmental challenge. This breakthrough comes as Caravel actively participates in the Shell GameChanger program, receiving crucial funding to explore the potential of its pioneering biocatalyst technology aimed at lowering carbon capture expenses.

Overcoming Traditional Carbon Capture Challenges

The traditional carbon capture methods have often been economically unviable, despite significant investments and development endeavors over the decades. Such projects have frequently underperformed or faced scalability issues primarily due to the high costs involved in the processes. Nevertheless, the current federal policy environment is increasingly supportive. In July 2025, the U.S. government preserved a key incentive, maintaining a $85 per ton tax credit for carbon capture under the Inflation Reduction Act. This initiative also expanded the utilization rate for carbon used in enhanced oil recovery or product conversion, further incentivizing cost reductions in this field.

Historically, the high energy demands related to carbon capture deployment have been the major economic barriers. Many companies have been utilizing amine-based solvents for CO2 capture due to their established efficiency in various environments. However, these amine solvents impose considerable energy costs after CO2 capture, significantly inflating the overall expenses.

The Breakthrough of Potassium Bicarbonate

Caravel’s new protein engineering platform suggests a revolutionary approach by utilizing potassium bicarbonate as a more efficient solvent alternative. This material can drastically reduce energy costs involved in the carbon capture process and lower the overall economic burden of establishing such systems. During its development, potassium bicarbonate proved its potential to cut energy requirements, yet it has always depended on robust enzymatic processes to function effectively.

With the aim of developing reasonably priced and high-performing enzymes, Caravel seeks to unlock the capabilities of potassium bicarbonate in a way that outperforms amine usage. According to Dr. Trevor Nicks, founder and CEO of Caravel, their cutting-edge technology doesn’t simply teach enzymes to perform tasks; it redefines their functional capabilities to maximize their potential. “While others have tried teaching enzymes to swim, we’re building the enzymes a boat and training them to sail,” he elaborated upon their innovative strategy.

Propelling Forward: Caravel’s Momentum

Since formally launching in October 2025, Caravel Bio has secured a $7.8 million grant from the National Science Foundation, showcasing its capacity to deliver pioneering products in DNA synthesis, animal health, and non-pollutive chemical manufacturing. The venture also focuses on uniting the historically fragmented protein discovery and delivery processes into an integrated system. This approach tackles significant industry inefficiencies that have caused costs to escalate and breakthroughs to remain confined to research laboratories.

The company's unique bioengineering technology seamlessly merges cell-free protein synthesis with bacterial spore display, dramatically expediting the evolution of protein creation and testing. By enabling researchers to examine millions of protein variants in parallel, Caravel is producing the data necessary to enhance machine learning models aimed at the field's advancement.

Collaborative Efforts and Strategic Partnerships

Caravel has garnered vital endorsements from eminent figures in the scientific community and has partnered with renowned institutions such as Avery Bio, Caltech, Rutgers University, and Oregon State University. Additionally, the company has joined the vHive Animal Health Incubator at the University of Surrey and established collaborations with Avery Bio and Rubi Labs, highlighting its position at the forefront of bioengineering innovation.

Overall, Caravel is not just aiming to revolutionize carbon capture but seeking to redefine the boundaries of what's possible with modern protein technologies. By combining cutting-edge science with strategic partnerships, the future looks bright for Caravel as it leads the charge toward a more sustainable industrial landscape.
