The paper, authored by Sai Gokul Subraveti (SINTEF), Elda Rodr\u00edguez Angel (TU Delft), Andrea Ram\u00edrez (TU Delft) and Simon Roussanaly (SINTEF), examines how CCS implementation in steel and cement production would have impacted the cost of the Lake Pontchartrain Causeway bridge in Louisiana, USA. The bridge is currently the longest beam bridge over continuous water in the world, and consists of approximately 225,000 m3<\/sup> of concrete and 24,209 tonnes of steel. This work was performed in connection with the Norwegian CCS Research Centre (NCCS)<\/a>.<\/p>\n\n\n\n

CCS would only impact part of the total cost<\/h2>\n\n\n\n

CCS has often been criticised for being too expensive. However, while many studies have already investigated the impact of CCS implementation on industrial plants, they do not examine the impact of CCS implementation on the end user. This is a significant gap, as most people do not buy raw materials such as cement or steel, but products that the cement and steel were used to create, such as houses or bridges.<\/p>\n\n\n\n

In terms of the case study, CCS initially resulted in a significant cost increase of raw materials: 60% for cement and 13% for hot-rolled coil (HRC) steel. However, as cement and HRC are only a part of the bridge construction cost, the overall cost increase due to CCS would be approximately 1%.<\/p>\n\n\n\n

\u201cCement and steel represent, in fact, only a small fraction of the total cost of building a bridge,\u201d explained Simon Roussanaly. \u201cAnd therefore, their impact is not as significant as it is perceived to be when you look solely at a cement and steel plant.\u201d<\/p>\n\n\n\n

1% increase in cost is more than reasonable for a 51% reduction in CO2<\/sub> emissions<\/h2>\n\n\n\n

For the 1% increase in cost, CCS implementation could have reduced CO2<\/sub> emissions associated with the bridge\u2019s construction by 51%. This 1% increase could be covered by a slight increase in the tolls already paid by the road user to access the bridge. Not only is this more than reasonable, the significance of a 51% emissions reduction cannot be ignored \u2013 particularly as the cement and steel industries together account for approximately 15% of the world\u2019s CO2<\/sub> emissions.<\/p>\n\n\n\n

\u201cThis case study clearly shows that a holistic approach must be applied with assessing the cost of CCS verses emissions reduction \u2013 not only at the component and material level, but as a whole,\u201d said SINTEF\u2019s Executive Vice President for Sustainability Nils R\u00f8kke. \u201cThis should encourage infrastructure developers and public purchasers to request low-emission materials in tenders and use this as a baseline for the environmental performance of new builds.\u201d<\/p>\n\n\n\n

The results from this case study illustrates how cities and governments could use public procurement of low-carbon materials to achieve their 2030 climate goals under the Paris Agreement at a reasonable cost. While more research is needed into the impact of CCS implementation on end-user products and services, we hope that this is the first step to a better understanding of the cost and benefits of CCS.<\/p>\n\n\n\n

Although not considered in this study, it is worth noting that further emission reduction could be achieved by, for example, using low-carbon hydrogen instead of coking coal as reducing agent.
