Heidelberg Makes Concrete Carbon Reductions
HEIDELBERG MAKES CONCRETE CARBON REDUCTIONS.
The Heidelberg Cement Group has embraced the daunting challenge of only producing CO₂ neutral concrete products. The Norwegian-based company – the world’s second-largest cement producer – has embarked on an unprecedented journey to remove carbon emissions from their energy-intensive production processes. To implement their “Zero Vision” of carbon neutrality, Heidelberg Cement has set a 2030 mid-term milestone of reducing carbon emissions 30%, compared to their emissions in 1990. Mr. Per Brevik, Director of Sustainability and Alternative Fuels for Heidelberg’s Northern Group described the company’s carbon capture project in a webinar hosted by 306 Energy. The pilot, at Norcem Brevik on the Norwegian south coast, is a strategic initiative on the company’s journey to net-zero carbon emissions by 2050. Is it possible for other heavy industrial manufacturers to also become carbon neutral? The Norcem Brevik pilot carbon capture initiative is building a pathway for the cement industry and others to follow. Steel and petroleum manufacturing could similarly follow the Heidelberg lead by embracing technology to capture and reduce carbon emissions. The CO₂ from Heidelberg’s production line will be liquefied and transported for storage under the North Sea at a facility called “Northern Lights”. Northern Lights will also be used by Equinor, Total and Shell to reduce carbon emissions from their operations. Per Brevik told the webinar audience that chemical processes are responsible for ⅔ of the carbon emissions from cement manufacture. He assured them that technically feasible solutions are available today for the capture of carbon from cement production. The high concentration of CO₂ in the flue gas stream presented the company with the best opportunity. Heidelberg conducted a multi-year study of four different technologies to identify the easiest one to scale up. The research and development project will capture almost 400,000 T CO₂/year – 50% of the total CO₂ emissions at the Norcem Brevik facility. This will still leave the company plenty of scope to scale up the technology or the flexibility to prove out other solutions in their drive to achieve 100% carbon emission reductions. The decision to implement the pilot is a significant commitment by the Heidelberg Cement Northern Group. While installing the technology over a number of years, the Company will still need to concurrently produce 1.3 million pounds of cement annually. The pilot project is capital intensive
