Explore our library of global case studies to learn how Capstone microturbines are aligning with businesses across various markets to improve their energy consumption through on-site power production. Since 1988, Capstone has shipped thousands of clean-and-green microturbines to customers around the world, logging millions of cumulative operating hours in the field. After all, Capstone is committed to improving the efficiency of the world’s energy infrastructure and reducing pollutants and greenhouse gas emissions.
When faced with a surplus of milk sugar, Gefu created an opportunity to generate onsite electricity and heat. Using 12 Capstone CR65 microturbines installed in a combined heat and power (CHP) application, Gefu converts waste milk sugar to generate about 6.5 Gigawatt Hours (GWh) of electricity. "We didn't know exactly what to do with the milk sugar. So, five years ago we decided to build a biogas plant to use the milk sugar as energy, and use the biogas in microgas turbines to produce electric energy. The main point behind this idea was to produce cattle feed without using or producing CO². We wouldn't have been able to do it if we hadn't built the biogas plant, and if we hadn't chosen the Capstone turbines, a new steamer, and hot air for spray drying plant. That gives us the efficiency, and that makes us the leader in producing cattle feed without CO²."
