Seawater for Sustainable District Heating Utilized in Holland
Duindorp, a small community near The Hague, Holland, has been the home of the world’s first district heating system which turns seawater into a sustainable source of energy. Realized in 2008, the system efficiently generates 15 kWh of heat from just 1 kWh of electricity. It uses intake valves to draw up to 190,000 gallons of seawater every hour into a facility that sends filtered water through five miles of pipes to 800 homes. During summer months, harbor water hovers around 70 degrees Fahrenheit, to which is boosted by in-home grid-connected heat pumps to reach 150 degrees for heating and warm water. In winter months, a 3MW exchanger is used to boost the temperature.
