Schlumberger has entered into an agreement with RTI International, a non-profit research institute, to accelerate the industrialisation and scale-up of its proprietary non-aqueous solvent (NAS) technology, which enhances the efficiency of absorption-based carbon capture.
The NAS technology will be applicable to capture CO2 across a broad variety of industrial emissions.
Gavin Rennick, president of Schlumberger’s new energy business, said: “With the world’s carbon budget running out, reducing emissions is a societal imperative.
“Carbon capture technologies are a key enabler in realising a low carbon future—and we are excited about this exclusive agreement to work with RTI on industrialising and scaling this innovative carbon absorption technology and bringing it to market.”
The NAS technology offers a compelling alternative to conventional aqueous solvent technologies for carbon capture, as it consumes less energy while retaining high CO2 capacity, resulting in a material reduction in operating costs.
The NAS technology is also less corrosive—eliminating the need for high-grade corrosion-resistant alloys and the associated increase in capital costs. This enhances the overall economics of carbon capture, utilisation and storage (CCUS) projects.
Dr Marty Lail, senior director of RTI’s decarbonisation sciences programme, said: “RTI has developed the innovative NAS technology over the past 12 years, progressing from lab scale to large engineering scale.
“NAS technology uses as much as 40 percent less energy during the CO2 capture process. High capture efficiency at lower energy cost is critical for widespread commercial use of carbon capture solvents.”
As part of an engineering-scale carbon capture demonstration funded by the US Department of Energy, NAS technology was able to remove >99 percent of the CO2 from natural gas combustion exhaust streams—the highest capture efficiency reported for any carbon capture solvent technology for this application.
RTI and Schlumberger will collaborate to develop models that enable fast design and process customisation to achieve a step-change in CO2 capture operations while leveraging Schlumberger’s global footprint to expand market opportunities for the technology.
