The Heineken Group, through Sociedade Central de Cervejas, Rondo Energy, and EDP, signed an agreement to electrify the heat supply and decarbonize the operations of its manufacturing plant located in Vialonga, in the Lisbon metropolitan area.
The project represents the first major heat-as-a-service agreement in the country, combining solar energy and thermal storage.
Heineken's global objective is to decarbonize its operations in scopes 1 and 2 by 2030, using a solution that allows for the generation of clean, emission-free steam.
The 100 MWh thermal storage equipment to be installed at the factory in Lisbon is one of the largest of its kind in the beverage sector worldwide.
Heineken project has already avoided emission of 2 million tons of CO2
Rondo's technology stores renewable electricity in the form of high-temperature heat, providing continuous steam, which eliminates the need for fossil fuel boilers.
The battery charges with intermittent, low-cost electricity, storing it in refractory bricks and supplying steam on demand.
The energy supply will be the responsibility of EDP, which will install a 7 MWp solar power plant in an area near the brewery. Additionally, the system will be charged with renewable energy from the grid through a flexible long-term contract, totaling 25 GWh per year.
With the implementation of this solution, the factory is expected to reduce its natural gas consumption, avoiding approximately 6.600 tons of CO2 emissions per year.
Thermal batteries are gaining ground worldwide.
With the increasing adoption of renewable energy sources and the need to store energy, thermal batteries are becoming established as one of the most promising solutions in the sector.
Countries such as Finland, Germany, Spain, and the United States already use this technology on a large scale to balance solar and wind power generation and reduce the use of fossil fuels.
The principle is simple. Excess energy — usually from renewable sources — heats materials such as molten salts, ceramics, sand, or graphite, which retain heat for extended periods. isolated systemsWhen needed, this heat is reused to produce steam, heat spaces, or power industrial processes.
The main types include molten salt systems, used in solar power plants Concentration heating. Applications range from district heating — such as the Polar Night Energy system in Finland — to replacing gas and oil boilers in industry, helping to reduce emissions and costs.
