Mokai is blessed with a sturdy geothermal resource. The Mokai geothermal power field is situated beneath the Trust’s land exactly where hot rock heats underground water to over 380°C. Deep wells enable the hot water and steam to be piped to the surface for commercial use.
Creating electricity with standard steam turbines requires operating fluids at temperatures of at least 150 °C. This is only possible with higher temperature geothermal sources of steam or superheated water which can be flashed to steam. The diagram under shows some of the doable variants when higher temperature water or steam is offered.
Rigs are hired from the oil business, so drilling will take place 24 hours a day to minimise the price. It will take around 20 weeks per properly. The rig will be one particular particularly for use in a populated area and heavily soundproofed, generating up to 45dBA at 200m. In the course of operation, the generator will make a continual noise: a maximum of 30dBA at a distance of 200m. But due to the fact buildings are low, the noise can be tempered by landscaping.
Iceland requires advantage of its incredible geological structure to use geothermal energy to their advantage. Not too long ago, it has been reported that 17% of Iceland’s total electrical energy production comes from geothermal energy. Iceland has reached uniquely high levels in the utilization of geothermal power, but the resource could be better utilized globally. Iceland is incredibly fortunate when it comes to energy as it gets virtually all of the rest of its electrical energy from Hydro-power dams.
Of course, the proper or lack thereof is immaterial for most homeowners. The simple fact is that the majority of residence owners currently don’t own a house that has flowing water on it, and geothermal vents are even rarer than flowing water as a percentage of land location. This leaves home solar panels and small scale wind power as the most extensively viable option energy choices on a personal level. Solar panels are additional versatile than wind turbines, simply because the wind flow is not uniform across all places of the country, whereas the sunlight that an area receives is relatively uniform, barring substantial land attributes that obstruct the sun in some locations.
