From Stony Brook to Global Climate Tech: Alum Helps Scale Carbon Removal from Lab Concept to Commercial Reality

For Siddhartha "Sid" Gadiraju, the path from Stony Brook engineering student to climate technology leader was as much about executing fundamental research as it was about learning how ideas move from lab benches into real infrastructure that can operate in the world at industrial scale.

Today, Gadiraju serves as the director of product at climate tech startup Carbo Culture, where he helps lead the commercialization of biochar-based carbon removal systems. The company converts waste biomass, such as agricultural byproducts that would otherwise be burned, into a stable carbon material that can store carbon for thousands of years while improving soil health and supporting energy production through process byproducts.

Gadiraju credits Stony Brook University, particularly the Department of Mechanical Engineering and its strong ties to industry, with preparing him for the technical and strategic demands of scaling "hard tech" solutions from concept to deployment.

"While I was learning thermodynamic cycles and core engineering theory, I was also gaining real industrial exposure working alongside industry veterans," Gadiraju said. "That combination made a huge difference in how I approached problems later in my career."

Building a Foundation in Industry-Connected Research

Gadiraju earned his master's degree in mechanical engineering from Stony Brook in 2014 before going on to complete a PhD at Virginia Tech. During his time on Long Island, he worked closely with Mechanical Engineeringfaculty and industry partners through the Advanced Energy Centerand the university's startup and Clean Energy Business Incubator (CEBIP).

His master's thesis work was conducted in partnership with ThermoLift, a startup with roots in Stony Brook's innovation programs. While many graduate students focused solely on academic research, Gadiraju was embedded in a startup environment, collaborating with experienced industry veterans with decades of field experience, and presenting technical work to company leadership early in his career.

That early exposure shaped how he viewed engineering problem solving. He points to a lesson from his graduate advisor that still guides his approach today: strong engineers combine theory, simulation, and experimentation rather than relying on a single method.

"The real world does not operate in just theory or just simulation," Gadiraju said. "You need balance across multiple approaches to build something that actually works outside the lab."

The experience helped him understand a broader reality that now defines climate technology development: technical success alone is not enough. Policy, market forces, and commercialization pathways all shape whether new technologies can succeed.

From Lab Scale to Commercial Scale

After completing his PhD and gaining additional industry experience, Gadiraju joined Carbo Culture at an early development stage, when the company's carbon removal technology was still at the proof-of-concept phase and far from large-scale deployment.

His role focused on one of the most difficult transitions in climate technology: scaling from lab or pilot systems to commercial infrastructure.

"When you move from lab scale to commercial scale, that is where many technologies fail," Gadiraju said. "It requires technical expertise, but also a different mindset about reliability, cost and operations."

Under his technical leadership, the company advanced toward full commercial deployment. Carbo Culture is now developing one of the world's largest biochar-based carbon removal facilities, with its first major commercial plant planned for construction in Europe later this decade.

The work represents a full pipeline example of how university-trained researchers can contribute to global infrastructure projects addressing climate and energy challenges.

What Green Jobs Really Look Like

Gadiraju emphasizes that the future workforce entering climate and energy fields should understand how green jobs differ from traditional engineering roles.

Many climate technology roles exist in startup environments, where teams are smaller and engineers must work across technical, operational, and strategic functions. Early-stage innovation frequently occurs in research environments, but long-term impact depends on teams that can translate those breakthroughs into real-world systems.

"Most green technology innovation is happening in startups and small teams," he said. "Students should understand that scaling technologies requires not just technical skill, but also adaptability and collaboration across disciplines."

He stresses the importance of policy literacy for engineers entering climate-related industries. Recent international carbon removal policy developments, he noted, highlight how regulatory frameworks can accelerate or limit technology adoption.

The Role of Stony Brook's Research and Innovation Ecosystem

Gadiraju points to Stony Brook's strong connections between research, industry collaboration and energy policy expertise as a key differentiator in preparing students for real-world technical careers.

Industry partnerships, applied research opportunities and exposure to professional networks helped shape his understanding of how technology, business and policy interact in energy and climate sectors.

He recalls how participation in energy conferences and research center programming expanded his understanding of climate challenges beyond technical design, including economic and policy considerations that influence deployment decisions.

For the Office of Research and Innovation and the Department of Mechanical Engineering, alumni trajectories like Gadiraju's reflect a broader institutional focus: supporting research that translates into real-world solutions while preparing graduates to lead technical innovation in industry.

From Stony Brook to Global Impact

Gadiraju's journey from graduate student to commercial climate technology leader underscores the growing importance of universities as launch points for the commercialization of advanced technologies.

From early industry exposure in graduate school to leading deployment of large-scale carbon removal systems, his career reflects a full innovation pipeline, one that begins in university labs and ultimately contributes to global infrastructure addressing climate and energy challenges.

"Stony Brook gave me the opportunity to work with industry while I was still learning core engineering fundamentals," he said. "That experience shaped everything that came after."
