The vision for the second stage is to reduce GHG emissions even more by switching from natural gas t P18 The major benefit of district energy is the ability to be flexible and opportunistic. Over time, local opportunities are expected to emerge that may lower costs or reduce GHG emissions. These may require negotiation with third parties to develop shared energy facilities like biomass or combined P19 RECOMMENDATIONS FOR WATER TREATMENT AND CORROSION PREVENTION IN DISTRICT HEATING SILHORKO-EUROWATER has supplied a new plant for producing make-up water for the district heating grid in Aalborg, Denmark.
