What is Carbon Capture and CCUS, and how does it work?
Carbon Capture refers to the process of capturing CO₂ from flue gas and industrial emissions before it enters the atmosphere. CCUS (Carbon Capture, Utilization, and Storage) includes capturing CO₂ and either storing it underground or utilizing it in products such as fuels or chemicals. Our CCUS solutions separate, purify, and prepare CO₂ streams for storage or industrial use.
How does biogas upgrading improve biogas quality?
Biogas upgrading involves removing carbon dioxide and other impurities from raw biogas to produce high-quality biomethane. This upgraded biogas can meet natural gas grid specifications or be further processed into liquified biogas such as Bio-LNG for use in transport and heavy-duty applications.
What is Bio-LNG and why is it important?
Bio-LNG (liquified biomethane) is a renewable fuel produced by liquefying upgraded biogas at cryogenic temperatures (around -160°C). Bio-LNG has a high energy density, making it ideal for heavy transport, maritime shipping, and other sectors where long-range, low-carbon fuel alternatives are needed.
What types of CO₂ can your purification and liquefaction systems handle?
Our CO₂ purification and liquefaction systems are designed to treat both high-concentration CO₂ streams and CO₂ captured via CCUS from industrial and biogenic sources. The purified liquid CO₂ meets industrial, food-grade, PtX, and EIGA Doc 70 standards, making it suitable for many applications.
How do your technologies support decarbonization goals?
Our range of solutions — including Carbon Capture (CCS/CCUS), biogas upgrading, biomethane production, CO₂ purification, and liquefaction — helps industries reduce greenhouse gas emissions, improve energy efficiency, and create value from waste gas streams. By transforming emissions into usable products like biomethane, Bio-LNG, and purified CO₂, we support the transition to a sustainable, low-carbon economy.
