The modernization of the district heating system in Lodi, Italy, was among the projects honored at the annual Global District Energy Climate Awards in Estonia this week. Improvements to the 11-year-old system include the addition of thermal energy storage tanks designed to store up to 10 MWh, with a peak charge/discharge of 5 MW.
Also honored were:
• A CHP system based on renewable biomass in Braunschweig, Germany. The new Hungerkamp system replaces 34 oil- and coal-fired boilers and is projected to eliminate 8,000 tons of CO₂ a year.
• A combined heating and cooling system in Helsinki, Finland. An overall 80 percent energy saving is projected for the system, which relies on seawater for both heating and cooling.
• A deep geothermal system in Kirchweidach, Germany. The system supplies residents with renewable heat and electricity and heats a 30-acre greenhouse that grows peppers and tomatoes that would otherwise be imported.
