Beer with solar steam: A theoretical case of energy transition in the agrifood industry

energy transition

The transition to clean energy sources in the agrifood sector is no longer just a vision — it’s becoming a reality, driven by the need to reduce emissions, improve energy efficiency, and decrease dependence on fossil fuels. Industrial processes such as cooking, pasteurization, and cleaning require large amounts of heat, and steam generation through solar technologies is emerging as a sustainable and cost-effective solution.

In this article, we analyze the case of a brewery in Valencia that has integrated a concentrating solar thermal system based on linear Fresnel collectors. This plant now covers 10% of its thermal demand using solar energy, avoiding the emission of 1,300 tons of CO₂ per year — an investment made viable through an energy sales model and public support.
