Geothermal energy has an ancient history. The Roman bathhouses relied on it to heat the water and also heat their homes. Geothermal was commonly used in Iceland and New Zealand to prepare meals.
In North America, some native tribes were able to use geothermal vents for heat and cooking. The exploitation of existing geothermal vents was a common means to tap into this source.
Now, the Hague has unveiled plans to employ geothermal heating, in this case, water from a hot well that is deep underground, to warm 4,000 homes and a number of industrial buildings. The introduction of geothermal heating is a part of the plan to reduce the city’s greenhouse gas emissions. The Hague aims to be CO2-neutral by 2050.
Geothermal may have an ancient lineage but this will be the largest such effort in the Netherlands, in addition the design is unusual.
A discovery was made that has rendered this possible. Water of 75 degrees Celsius (170 degrees Fahrenheit) was found at a depth of 2,200 meters (7,200 feet) in the southwest of the city.
"This geothermal energy will be transported to the district heating network through heat exchangers Via this network of pipes the energy eventually will be distributed to the houses," which would be equipped with under floor heating instead of a radiator.” The Hague's housing department
The project is projected to be able to be completed for a cost of euro46 million (US$62.6 million), or euro11,500 (US$15,640) per house. The Hague has stated that residents will be given a guarantee that their heating bills will be, equal to or less than those of people using regular heating.
There is a need to use some electricity to run the pumps but the project would result in a net savings of 4,000 tons of carbon dioxide annually. This is an inexhaustible source and will not emit any hazardous gases.
There are geothermal projects established in Reykjavik, Iceland, and Boise, Idaho. This is a growth industry and smaller projects are opposing up in many places.
