The targets for lower emissions of carbon dioxide from Europe's basic industries are out of reach, without the urgent introduction of innovative carbon dioxide mitigation technologies. Researchers at Chalmers University of Technology in Sweden draw this conclusion after several years of research into carbon-intensive industry in Europe.
"There is an urgent need to demonstrate and implement carbon capture and storage, CCS, and other carbon dioxide mitigation technologies", says Dr Johan Rootzén. "While this will involve major investments in primary production, our results suggest that there will only be marginal impacts on costs and prices in the end-use sectors."
The debate about how to reduce emissions of carbon dioxide often focuses on emissions from generation of electricity and transport. Johan Rootzén has researched another major source of emissions: energy-intensive heavy industry in Sweden and the EU, such as oil refining, and production of cement and steel.
"There is a lack of strategy from political actors about how emissions from these industries should be reduced, even though these industries are responsible for a tenth of emissions of carbon dioxide in Europe and nearly 20% in Sweden", says Johan Rootzén. "At the same time Sweden and the EU have a target in which emissions should be almost zero by 2050."
Making production more energy efficient and changing to fossil free fuels are two of the alternatives which are often mentioned, but when it comes to the production of cement and steel, it is only possible to tackle a limited amount of emissions with these measures, due to the method of production. One way to reduce emission would be to reduce production, but major investments in housing, infrastructure and renewable energy are foreseen over the coming decades which are likely to result in a continued high demand for bulk products like steel and cement.
"The clock is ticking", says Johan Rootzén. "Plants within heavy industry have very long lifespans, so implementation of new technology and new solutions take a long time. There are only a few investment cycles left to year 2050. If the EU is serious about reducing emissions by 80-90 % by 2050, then the issue of how to finance the development and implementation of innovative process technology must be brought to the table now."
"It is easy to say that we should achieve zero emissions, but this requires that we take the issues seriously and are given the opportunity to demonstrate new technologies; CCS as well as other mitigation options. There are indeed question marks concerning CCS, and large investments are required in CCS as well as in other measures. Yet, if society decides not to try then we limit the room for manoeuvring in the future. Our research suggests that without a shift in technology then refineries, steel and cement industries alone are going to be the source of up to a quarter of the emissions in 2050", says professor Filip Johnsson, who has been leading the Chalmers research.
