Who we are

At Captured Carbon, we believe the energy transition needs more than ambition — it needs expertise, innovation, and trust. Since our founding in 2007, we’ve built a reputation as a partner that understands the commercial realities of energy and helps clients succeed in a complex market.
We sit at the intersection of trading, regulation, and strategy. By combining market insight with hands-on experience, we deliver solutions that give our clients clarity, confidence, and competitive advantage.
Our work spans the entire energy ecosystem — from independent generators to utilities, investors, and corporate energy buyers. What unites them is a shared goal: to unlock value today while building a sustainable future.
