Automation is transforming the way industrial systems are managed around the world, making them more efficient and sustainable. And if we add renewable energy to the equation, the result is an industrial revolution that does not compromise the environment. Industries are increasingly interested in methods that use clean energy to power their automatic systems, creating a virtuous circle of efficiency and sustainability.
Automation of industrial systems powered by renewable energy
Combining automation with renewable energy sources allows industries to reduce their dependence on fossil fuels, minimising carbon emissions. In Spain, according to the Institute for Energy Diversification and Saving (IDAE), renewable energy consumption reached 46% of the country’s total in 2021, driven by policies and regulations such as the Electricity Sector Act 24/2013.
How is automation applied in industry using renewable energy?
Today, industries are using different technologies to automate key processes on production lines. Digital control systems, smart sensors and collaborative robots are some of the tools that make it possible to integrate renewable energy, such as solar or wind, into industrial processes. Constant regulation of, for example, the energy flow optimises consumption and improves the overall efficiency of the system. This management can be done in real time, adjusting the amount of renewable energy needed according to current demand.
What are the economic and sustainability benefits of these implementations?
Adopting automated systems that run on renewable energy benefits companies in several ways. The savings in energy costs are significant, on top of the reduction in environmental impact. According to a study published by Fraunhofer ISE, the levelised cost of electricity (LCOE) of renewable energy has fallen dramatically over the last decade. In addition, by integrating automation and clean energy, industries improve their corporate responsibility and their image with consumers and customers, increasing their brand value.
What challenges do companies face in the transition to these systems?
It is not all a bed of roses, of course. The transition to automated systems powered by renewable energy can run into obstacles, such as high initial investments in infrastructure and staff training. However, the long-term benefits, both economic and in terms of sustainability, outweigh these initial challenges. It is also essential to make sure that renewable energy infrastructure is reliable and well maintained to avoid supply interruptions.
A success story in Spain
A successful example is the El Prat de Llobregat desalination plant, which uses renewable energy to run automated systems that manage the desalination process. The plant has integrated solar panels to power its systems, showing how the integration of clean technologies can increase efficiency and productivity while reducing environmental impact.
FAQ
