Brewing beer can be a highly polluting activity because gas boilers are normally used to create the enormous volumes of steam required for the process. Now, Heineken is teaming with a battery and electric company on a new solution at its Lisbon, Portugal brewery. They’re building a 100MWh grid- and solar-powered heat battery that will generate the steam while reducing carbon emissions, Heineken announced.
Heat batteries use materials like ceramics to store and then release heat, much as a regular battery stores and releases electricity. Heineken’s brewery will employ a Rondo Heat Battery (RHB) built with refractory bricks that capture heat, then convert it to steam. When completed, it will be powered by onsite solar and renewable electricity from EDP and supply 7 MW of steam — enough to run the brewery 24 hours a day. When the system goes live in April 2027, it will be one of the largest heat battery systems in the beverage industry.
It’s a significant milestone for the industry, as high temperature steam is one of the hardest things to produce with electricity. It’s a key part of Heineken’s goal to hit net zero carbon emissions by 2040 while also being a win for Portugal, which aims to reduce greenhouse gas pollution 55 percent by 2030.
The system will be hands-off for Heineken, as EDP will take care of building and running it, and Rondo will supply the battery technology. “This project not only helps us reduce our reliance on conventional energy, it shows how practical innovation and strong partnerships can deliver meaningful improvements across our supply chain,” said Heineken VP Magne Setnes.
