Italian Company Using Trigeneration Plant for Clean Energy

Bio-on, an eco-sustainable chemical technologies company, and Gruppo Hera, one of Italy’s main multi-utility providers, have reached an agreement for the supply of clean energy thanks to the a newly designed trigeneration plant.

The 1 MW trigeneration plant will guarantee clean electric energy for the new biopolymer production plant, currently under construction outside Bologna. Trigeneration, or combined cooling, heat and power (CCHP), is the process by which some of the heat produced by a cogeneration plant is used to generate chilled water for air conditioning or refrigeration. An absorption chiller is linked to the combined heat and power (CHP) to provide this functionality.

Through the agreement, Gruppo Hera will supply Bio-on’s new plant with a) power produced and self-consumed, b) heating in the form of steam, and c) cooling. The multiannual agreement includes the realization and maintenance of the entire technological-energy hub associated with the supply of energy, for a total investment from Hera Servizi Energia of 2.4 million Euro.

The energy saving generated is over 800 TOE (tonnes of oil equivalent) per year.

Trigeneration in the US

Municipalities across the US have begun to embrace trigeneration plants for clean energy production. Last month, Lancaster General Hospital in Pennsylvania invested $28 million into a trigeneration energy center to “improve system reliability and increase energy efficiencies,” according to

And way back in 2015, M Street Homes, a Houston-based custom homebuilder, installed a “micro-trigeneration system” to power, heat and cool a 4,500-square-foot home in Texas.

In 2014, the Horseshoe Casino in Baltimore, Maryland, installed a Series 4000 CHP system along with a complementary diesel-powered Series 1600 emergency backup generator set. The system produces 1,149 kW of electricity and 4,137,000 Btu’s of heat per hour.
