Rondo Energy and energy producer EDP are installing a massive 100 MWh renewable-powered heat battery at HEINEKEN’s brewery in Lisbon, Portugal. The project will deliver round-the-clock renewable steam and reduce emissions without altering the facility’s beer brewing process.
Brewing HEINEKEN with zero-carbon steam
The Rondo Heat Battery (RHB) will be the biggest deployed in the beverage industry worldwide. It can store electricity as high-temperature heat using refractory bricks, then convert that heat into 24/7 steam, all without burning fossil fuels.
At HEINEKEN’s Central de Cervejas e Bebidas Brewery and Malting Plant, the heat battery system will supply 7 MW of steam, powered by renewable electricity from onsite solar and the grid. That steam is identical to steam created by gas-fired boilers, but without the carbon pollution.
EDP is providing the renewable electricity and will deliver the steam directly to HEINEKEN via a Heat-as-a-Service model. Rondo is supplying the battery, and HEINEKEN gets to ditch fossil fuels without retooling its brewing process.
Why this matters
This project is a big win for industrial decarbonization. High-temperature steam is one of the most complex parts of manufacturing to electrify, and the beer industry runs on it. HEINEKEN’s Lisbon site already uses solar panels for electricity and electric heat pumps for hot water, and this move helps it go even further.
It’s part of HEINEKEN’s “Brew a Better World” plan to hit net zero emissions by 2040 and decarbonize all of its global production sites by 2030.
Additionally, the deployment aligns with Portugal’s national target of reducing greenhouse gas emissions by 55% by 2030.
The bigger picture
With the European Investment Bank and Breakthrough Energy Catalyst backing this and other Rondo projects with €75 million in funding, this Lisbon installation is just the beginning. Rondo’s technology enables energy-hungry industries to switch from fossil fuels to renewable electricity without compromising 24/7 operations.
Rondo CEO Eric Trusiewicz sums it up: “We are thrilled to be installing our first Rondo Heat Battery in Iberia, and to support HEINEKEN to reach its goals. We look forward to helping industries across Iberia cut costs and carbon, and help Iberia capitalize on the opportunity.”
