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 ΓÇö
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.
