Industrial decarbonization through a sustainable energy mix
The energy decarbonization of the brewing sector is already a reality thanks to the combination of different energy sources. Beyond electrification, the challenge lies in jointly addressing both electrical and thermal demand—two key areas in production processes.
In the brewing industry, a large share of energy consumption is dedicated to process heat (for example, wort boiling, steam generation, or cleaning), which makes it essential to integrate various technologies capable of meeting these needs efficiently and sustainably.
To achieve this, the model is structured into two major energy blocks:
Electrical Scope
Electrical demand can be met through renewable solutions such as:
- On-site photovoltaic installations, which allow energy to be generated directly at the plant.
- BESS (Battery Energy Storage Systems), storage solutions that maximize energy coverage and reduce power peaks.
- PPA contracts, which guarantee long-term supply of renewable electricity.
These tools help reduce indirect emissions and provide greater stability against electricity price volatility.
Thermal Scope
Process heat represents the main challenge. To decarbonize it, the energy mix combines different technologies:
- Solar boilers, capable of generating steam from solar energy (Fresnel – LFR requires less space, has lower wind exposure, and low reflectivity compared to Parabolic Trough – CSP).
- Industrial heat pumps, which improve efficiency by using waste heat or low‑temperature sources.
- Biomass, a dispatchable renewable source using local resources with a low logistical footprint.
- Electric boilers, which enable partial electrification of thermal demand.
- Biomethane, obtained from the digestion of industrial waste or through guarantees of origin.
Combining these solutions allows for the progressive replacement of gas and the adaptation of the energy system to the specific needs of each brewing process.
A More Efficient and Resilient Model
This energy‑mix approach not only reduces emissions but also:
- decreases dependence on fossil fuels
- improves energy efficiency
- provides greater cost stability
- strengthens the plant’s resilience to changes in the energy environment
Conclusion
Decarbonizing the brewing sector is achievable through an integrated approach that combines electrical and thermal solutions. Using a diversified energy mix enables progress toward more sustainable, efficient production models that are prepared for future energy challenges.
