The sector is already working on solutions for ‘green’ cement, i.e. produced climate-neutrally.
Das Verfahren wird aber auch durchaus kritisch gesehen. Zu Recht?
Natürlich ist CCUS nicht die Lösung für die Klimakrise. Die Notwendigkeit, CO2-Emissionen nach Kräften zu vermeiden, besteht weiterhin. Aber die Technologie ist – auch, was unterirdische Lagerung des CO2 anbelangt – sicher. Aus allen diesen Gründen ist CCUS ein wesentliches Element in den Szenarien vieler Experten und namhafter Forschungsinstitute, etwa der Internationalen Energieagentur. Auch wir bei SICK sind davon überzeugt, dass das Binden, Lagern und Nutzen von CO2 für den Klimaschutz unverzichtbar ist. Denn, das kann man nicht genug betonen: Uns läuft die Zeit davon, wir müssen handeln. Und Carbon Capture ist eine Technologie, die eben schon heute auf bestehende Anlagen über Nachrüstungen angewendet werden kann und auch neue großtechnische Anlagen ergänzt. Deshalb wollen wir uns hier mit unseren Lösungen noch stärker einbringen – auch wenn das aufgrund von Kritik am Verfahren eventuell auf den ersten Blick nicht nachvollziehbar ist.
But the process is also heavily criticized. Justifiably?
Of course CCUS does not solve the climate crisis. We still need to avoid CO2 emissions as far as possible. But the technology is safe, including the underground storage of CO2. So for all these reasons CCUS is an important component in the scenarios of many experts and well-known research institutes, such as the International Energy Agency. We at SICK are also convinced that binding, storing and reusing CO2 is indispensable for climate protection. Because, and one cannot stress this enough, we are running out of time – we have to act. And carbon capture is a technology that can already be applied to certain plants by retrofitting them, and it will also be installed in new industrial plants. That’s why we want to get more involved here with our solutions – even if this may not seem to make much sense at first glance, given the criticism of the process.
What solutions does SICK offer for CCUS applications and technologies?
Carbon dioxide is emitted from a variety of sources, collected and transported via pipelines or ships for further processing, such as storage or utilization. We already offer gas analysis devices that monitor process and emission parameters for the separation process in the CO2 scrubbing plants. Gas flow measurements are required for the subsequent transport of the pure CO2 at every transfer point: The quantity and quality of the gas, and any impurities it may contain, must be monitored – to protect health and the environment, as well as to guarantee accurate invoicing with the companies, or the calculation of CO2 levies and credits. SICK already has solutions that support these CO2 transport applications. Some of our FLOWSIC models are already suitable for use in CO2 pipelines, and measure the exact gas quantity at every transfer point in the pipeline. The next step is to further develop our products so that they are also suitable for quality assessment and, for example, can detect any traces of water that could have a corrosive effect on the pipes. So CCUS offers many potential areas of application for our sensor solutions. We see great potential for this technology – for us as a company, but also for climate protection.
