BioUpp provides a patented biomethanation system that captures surplus renewable electricity and CO₂ from biogas plants to produce injectable biomethane via a gas‑liquid bioreactor and proprietary microbial catalyst. The technology boosts methane yields, stores excess energy as gas, and reduces emissions, enabling utilities, agricultural digesters, and renewable producers to integrate low‑carbon gas into existing natural‑gas networks.

Problem
Renewable electricity generation often produces excess power that cannot be stored, leading to curtailment, while biogas facilities release a significant portion of CO₂ from the raw biogas into the atmosphere. This results in wasted renewable energy and unnecessary greenhouse‑gas emissions.
Solution
BioUpp’s patented biomethanation technology captures surplus renewable electricity and the CO₂ emitted during biogas production, converting both into injectable biomethane. The process uses a gas‑liquid bioreactor with pneumatic agitation, a protected microbial catalyst, and immobilisation supports that enable continuous regeneration of the catalyst. By integrating power‑to‑gas conversion with CO₂ capture, the system increases methane yields, stores excess energy in gas form, and reduces overall CO₂ emissions. The resulting biomethane can be injected directly into existing natural‑gas networks, providing a flexible, low‑carbon energy carrier for utilities, agricultural digesters, and renewable‑energy producers.
Target Audience
Primary customers are utility operators, agricultural biogas digesters, and renewable‑energy producers seeking to enhance methane output, store excess electricity, and lower carbon footprints.
