The chemical industry in Spain is accelerating its efforts to transform its production processes and move away from dependence on fossil fuels. This is no easy challenge, given that we are talking about a sector with a very intensive energy consumption and emissions that come not only from burning fuels, but also from the chemical processes themselves. However, collaboration between technology companies and government is enabling solutions to emerge that until recently seemed unattainable in terms of cost-effectiveness.
In recent months, it has become clear that the transition to a climate-neutral industry is not just a matter of environmental ethics, but a pure competitiveness strategy in the European market. Through innovation in storage and the use of its own renewable sources, the sector is demonstrating that it is possible to manufacture cleanly without the energy bill skyrocketing, opening the door to a new era of chemical production in the country.
The electrification of industrial heat and thermal storage
One of the most significant milestones has occurred in the Álava region, where a chemical plant has become a pioneer by fully electrifying its heat production. This advancement involves replacing the old oil-fired boilers with a system that combines solar energy with... Thermal storage in molten saltsThis allows for continuous steam generation. The technology used is capable of reaching temperatures close to 400 degrees, meeting the factory's needs with an efficiency approaching the theoretical maximum.
This type of project relies on large-scale self-consumption photovoltaic installations that power the storage systems. Around 85% of the energy needed is generated directly from the sun, while the remainder is supplemented by the electrical grid, achieving of scope 1. In this way, more than a thousand tons of carbon dioxide are prevented from being released into the atmosphere each year, setting a real precedent for other factories in the sector that are looking for replicable solutions.
The viability of these investments would not be possible without the support of public instruments that seek to reduce financial risk. Programs such as the And the European NextGenerationEU funds are injecting millions of euros to make the energy transition a reality. These incentives not only help with the purchase of machinery, but also make projects more bankable in an environment where energy prices are often quite volatile and generate some uncertainty.
Green hydrogen as a vector for large industry
Beyond direct electrification, green hydrogen is emerging as the key to high-temperature processes that still rely on natural gas. In regions like the Valencian Community, large-scale infrastructure is being built for this purpose. which will supply both refineries and chemical plants. This move aims to replace gas with domestically produced energy, strengthening energy independence and lowering the carbon footprint of essential everyday products.
The sector's strategy involves a clear roadmap where energy efficiency is the first mandatory step. Before implementing complex technologies, companies are optimizing their current consumption, since addressing energy expenditure allows them to... reduce emissions immediately and serves as a foundation for the rest of the innovations. Furthermore, CO2 capture and utilization remains on the horizon as a necessary solution for those process emissions that, due to their chemical nature, cannot be eliminated simply by changing the energy source.
It is essential to understand that this structural change requires a coordinated effort between research centers, government agencies, and the companies themselves. The ultimate goal is to consolidate an ecosystem where circular economy and sustainability These shouldn't be just empty words, but the foundation of a strong chemical industry capable of leading the European market. The progress achieved in specific plants is already sparking interest from other industrial groups who see these solutions as the path to securing their future.
The transformation underway in Spain's chemical industry reflects a firm commitment to achieving climate neutrality in the coming decades. Thanks to a combination of electrification, thermal storage, and the deployment of green hydrogen, factories are achieving decouple its growth from emissions pollutants. The key to success lies in maintaining this pace of investment and collaboration, ensuring that each technological advance has the necessary financial and regulatory backing so that the industry continues to be the economic engine that the country needs.
