Dugu Systems builds low‑pressure simple‑cycle gas turbines that run on oxygen and fuel, using a high‑purity CO₂ working fluid that can be captured and sold. By operating at low pressure, the turbines use inexpensive materials while delivering about 40% electrical efficiency and supporting multiple fuels, providing clean, low‑cost power and an additional revenue stream from CO₂ capture.

Problem
Conventional gas turbines rely on high-pressure, high-temperature cycles that require complex, expensive materials and components, leading to high capital costs, maintenance challenges, and limited fuel flexibility. Additionally, traditional designs emit CO₂ directly, missing opportunities for carbon capture and revenue generation.
Solution
Dugu Systems offers a low‑pressure simple‑cycle gas turbine that operates on oxygen and fuel, using a high‑purity CO₂ working fluid that can be captured economically. By reducing operating pressures, the turbine can be built from simpler, lower‑cost materials while achieving high electrical and thermal efficiencies (≈40%). The design supports a range of fuels—including natural gas, field gas, propane, and biogas—providing flexibility for diverse energy markets. In‑combustion CO₂ capture creates an additional revenue stream by selling high‑purity CO₂ to industrial users. The result is clean, cheap power with multiple value streams from a single engine platform.
Target Audience
Primary customers are utility generators, industrial facilities, and process‑intensive plants (e.g., biorefineries, chemical and food processors) seeking efficient, low‑cost power and heat, as well as companies in the CO₂ market looking for a reliable source of high‑purity carbon dioxide.
