Birra Peroni
Bari
Birra Peroni, part of the global Asahi Group, is committed to achieving zero carbon emissions across its brewing facilities by 2030. In June 2023, the company commissioned a solar thermal system at its Bari brewery in southern Italy, working with Absolicon, a specialist in high-performance solar thermal technology.
The installation consists of a ground-mounted field of Absolicon’s patented T160 parabolic trough collectors, covering a reflector area of 660 m² and delivering 460 kW of renewable thermal capacity. The Absolicon T160 collectors track the sun with high precision, concentrating over 76% of direct solar radiation onto an absorber tube that converts it into heat. This produces hot water or steam up to 160 °C with long-term durability, enabling a reliable, renewable heat supply for industrial processes.
The solar field integrates with a heat exchanger and a 30 m³ hot water storage tank to supply the brewery’s pasteurisation process with renewable heat, storing up to 2 MWh for nighttime operation. The installation produces around 349 MWh of hot water or 366 MWh of steam annually, avoiding approximately 77 tonnes of CO₂ emissions per year by displacing inefficient natural gas boiler system.
Heat is half of the final energy consumption and heat accounts for 40% of the CO2 emissions. Absolicon has created a concentrating solar collector that can produce heat and steam up to 160 C that can heat both industrial processes and district heating networks. Many industrial processes consume large amount of heat. To make one kilo of textiles, two kilos of coal is used, to make one ton of tea, five tons of fire wood is burnt. Using the sun has heat source, this can be changed. The Absolicon T160 has the highest ever measured optical efficiency for a small parabolic trough (less than 2 m). Over 76% of the direct solar radiation is converted to heat. The collector is following the sun within a fraction of a degree. The result is heat and steam up to 160 C that can be used in industries, district heating or solar cooling.
