The beer company partnered with Rondo Energy and EDP on this first Heat-as-a-Service agreement in Portugal, combining solar power and thermal storage to decarbonize industrial processes through heat electrification.
The battery charges with intermittent solar and low-cost electricity, says Rondo, then stores electricity as heat in refractory brick, and delivers steam on demand at any conditions up to over 100 bar, with no combustion and no emissions.
Additionally, says Rondo, the heat battery harvests this electricity with a cost of storage lower than any chemical battery, to supply energy low enough in cost to replace fossil fuel steam.
It can deliver continuous 24-hour, zero-carbon steam, heat and/or electricity, serving as a drop-in replacement for fossil fuel-fired boilers or cogeneration systems.
