The Stanford Energy System Innovations (SESI) project is a $438 million major transformation of the campus district energy system. The transformation is from gas fired combined heat and power with steam distribution to electrically powered combined heat and cooling with hot water distribution. When completed in April 2015, the new heat recovery system will be 52% more efficient than the existing cogeneration system

Test system design and measurements of the thermal conductivity for composite pipesA significant fraction of human energy consumption is used for heating purposes thus efficient and durable insulation is a necessity. Although different materials have been used to insulate district heating pipes over the last decades only few studies have been conducted on the long-term aging effects.

Before heating season 2009/10. PUC “Beogradske elektrane” burns up to 10.000 tons of coal per year. Besides high emissions of SO2, CO, NOx and particulates there is a serious problem of ground contamination with coal and ash during transport, handling and storage. This is another important reason for introduction biomass in coal fuelled boilers and thus further decreasing the consumption of coal and introduction of renewable.

The subject of our application is a district cooling system in the city of Velenje, Slovenia. There the cooling energy is produced in absorption chillers. The heat for their operation is supplied from an existing district heating system. In it the supply temperatures are sufficient to power the absorption chillers through the whole year, due to industry consumers.

Integration is the hallmark of District Energy St. Paul’s system. From its inception, District Energy St. Paul envisioned a future that used district heating and cooling infrastructure to integrate a variety of local, renewable energy sources and technologies. District Energy has doubled the amount of buildings served from 1985, yet is producing less carbon thanks to the incorporation of biomass, CHP, and solar.
