Unitel Technologies, Inc. has successfully demonstrated its Merlin process, a carbon capture and utilization (CCU) technology designed to produce blue methanol. By converting captured carbon dioxide into high-value fuel, the company aims to transform zero or low-cost vented waste streams into profitable commodities, offering a strategic alternative to traditional carbon sequestration methods for industrial operators.
Merlin Process CO2 Conversion Metrics
The Merlin process is engineered to consume 30,000 tons per year of captured carbon dioxide to generate 73,000 tons per year (approximately 200 tons per day) of blue methanol. Unitel is currently deploying this technology at a facility in Danyang, South Korea, which produces 10,000 tons of methanol annually. The process is specifically optimized to integrate with existing ethanol plants, leveraging consistent supplies of fermentation-derived carbon dioxide. This integration utilizes established onsite resources, including natural gas, power, workforce, and existing industrial infrastructure, to maximize the economic efficiency of the methanol production cycle.
Methanol Market Demand and Economics
The economic viability of the Merlin process is positioned against a robust North American market. In 2025, U.S. methanol demand reached approximately 11.5 million metric tons, with market prices ranging from $1,000 to $1,400 per ton. Demand is projected to climb to 18 million tons per year by 2035, driven largely by the marine fuel sector. Unlike carbon capture and storage (CCS), which yields net profits of $55–$65 per ton of CO2 after tax credits, Unitel’s CCU approach targets higher margins. Furthermore, Unitel avoids the high costs of electrolytic hydrogen, which can reach $5 per kilogram, potentially costing $1,000 per ton of methanol.
Key Takeaways
- The Merlin process converts 30,000 tons of CO2 annually into 73,000 tons of blue methanol.
- U.S. methanol demand is forecasted to reach 18 million metric tons per year by 2035.
- Unitel's technology is currently operational in Danyang, South Korea, producing 10,000 tons per year.
EnergyInsyte's Take
In our view, Unitel’s Merlin process represents a pragmatic shift from carbon sequestration to carbon utilization. By targeting ethanol plants, the company bypasses the prohibitive costs of electrolytic hydrogen that plague other CCU methods. This strategy transforms a liability—vented CO2—into a high-demand commodity for the marine and chemical sectors. For industrial leaders, this signals a move toward circularity where waste streams directly subsidize the transition to low-carbon fuel production.
Questions & Answers
How does the Merlin process compare to traditional CCS economics?
While CCS provides a net profit of $55–$65 per ton of CO2 via tax credits, the Merlin CCU process generates value by converting CO2 into methanol, which commands market prices between $1,000 and $1,400 per ton.
What makes the Merlin process more viable than hydrogen-based CCU?
Other CCU methods rely on electrolytic hydrogen, which costs approximately $5 per kilogram. This feedstock alone can cost $1,000 per ton of methanol, making the Merlin process more economically sustainable.
Which industrial sectors will drive methanol demand through 2035?
Primary demand comes from biodiesel, chemicals, and resins, but the marine fuel sector is expected to significantly increase total demand to roughly 18 million tons per year by 2035.
Where is this technology currently being deployed?
Unitel has already implemented the technology at a plant in Danyang, South Korea, which currently produces 10,000 tons of methanol per year.
