The final speaker of gasworld’s ‘Europe CO2 Summit 2022’, Rob Niven – Chair and CEO of CarbonCure Technologies, discussed CarbonCure’s efforts to remove 500 million tonnes of CO2 annually by 2030.
Providing context, Niven stated that cement is responsible for around 7% of annual global greenhouse gas (GHG) emissions, primarily due to process emissions.
“Cement makes up only 12% of the weight of concrete, but is responsible for 95% of concrete’s carbon footprint, revealed Niven.
How can industry reduce emissions for cement?
Niven stated that carbon capture, utilisation, and storage (CCUS) is where the vast majority of decarbonisation of industry will occur.
With an aim to reduce and remove 500m metric tonnes of annual CO2 emissions by 2030, CarbonCure takes CO2 supplied by the industrial gases industry and injects it into concrete following mineralisation.
The technology used by CarbonCure is retrofitted via installation, integration, and injection.
“The CO2 is sourced from the industrial gas industry, that CO2 is then used to supply concrete producers, just as it would with any other regular CO2 consumer whether it be food and beverage, or other industrial applications,” Niven explained.
“Typically, on a concrete truck, around 91kg of CO2 will be saved per truckload.”
Various projects across the globe are using CarbonCure’s technology, including ExxonMobil’s gasification plant in Singapore, Amazon’s HQ2 in Arlington, Virginia, and the LinkedIn Campus in Mountain View, California.
“Technologies like these are critical to help this industry transition and continue to supply this product which is essential for humanity to continue to develop,” Niven concluded.
All sessions of gasworld’s virtual ‘Europe CO2 Summit’ will be available to watch on-demand.
