We know that some of the industrial processes that we use the most are very difficult to decarbonize, such as the production of iron, steel, cement, and other chemical processes. Unfortunately, these processes account for a quarter of all polluting emissions, and as these materials are used more every day, they represent a significant challenge for the Climate Crisis in which we find ourselves.
That is why I found an article that appeared in Joule magazine titled: Assessing the potential of decarbonization options for industrial sectors that is quite interesting, and which can be downloaded in PDF format at: https://www.cell.com/joule/pdf/S2542-4351(24)00026-6.pdf
In this article, researchers from the University of Leeds indicate that 85% of these polluting industrial emissions could be eliminated with current means that have a medium or high degree of technical maturity. And I think that is very important and positive news.
Many of the emissions from industries come from the energy they use and the enormous heat required by certain industrial processes and that can be solved with the use of sustainable electrical energy. What happens is that in many cases this is more expensive, and industries do not do it in order to sell their products at more competitive prices.
In the case of certain chemical processes, CO2 is emitted naturally, but that CO2 could be captured at the time it is produced, and eliminated so that it does not reach the atmosphere. There are already various procedures in operation, and they should be promoted and financed to reduce their costs.
The positive message is that: decarbonizing the most polluting industrial processes is technically possible. What is needed is to have the political will to do it, and to support and finance the technologies that allow it.
The absurd thing today is that we are subsidizing polluting activities such as air transport to go on vacation, and many other activities, and we are not taking advantage of those economic resources to support the decarbonization that we so need.
The day we decide to do it, it will be much later and it will cost us much more. But dear friends, humans are fundamentally thinkers in short term.
