Reducing the viscosity

of solvents to lower 

the cost of CO2 capture.​

At RoCo, we are developing an additive capable of significantly reducing the viscosity of water-lean chemical solvents to increase heat exchanger and mass transfer efficiency. As a result, we are lowering capital and operating costs for CO2 capture.


The project is aimed at a reduction in the cost of CO2 captured of $2 per tonne or greater, leading to the commercial deployment of a transformational solvent-based technology for coal-fired power plants to meet the U.S. Department of Energy's (DoE's) Carbon Capture Program goal of approximately $30 per tonne of CO2 captured with 95 percent CO2 purity.




Advanced membrane

and hybrid technology help

cut down capital cost.

RoCo developed and validated a transformational hybrid membrane/solvent system for the capture of carbon dioxide (CO2) from flue gas. The hybrid technology is a two-stage CO2 capture system which combines a membrane separation process and an absorption/stripping process with heat integration through a heat pump cycle.


To reduce capital cost, a next-generation membrane technology with higher permeance was developed. Since permeance is directly tied to membrane area and capital cost, the new interfacially-controlled envelope (ICE) membranes will reduce the capital cost of the hybrid process below that of the baseline technologies.

One-pot process cuts cost

of CO2 utilization to open up

new material possibilities.

In the past, RoCo has innovated various cost-effective technologies for CO2 separation and utilization of cyclic carbonates by developing poly(hydroxyl urethane) based binders and adhesives for various applications. More recently, we developed a new one-pot process for directly and efficiently converting olefins to cyclic carbonates.

RoCo’s patented and exclusively licensed technologies of triazolium-based ILs is used for CO2 capture by directly converting various olefins to their corresponding cyclic carbonates in the presence of an oxidative catalyst. This revolutionary method not only has the economic advantage of a one step process, but also opens up new possibilities for designing and developing novel cyclic carbonate or poly(hydroxyl urethane) based functional materials with tuneable or tailoring properties.
