“Sustainability” can be considered to give long- term energy product without interruption at power generation. Each power factory type may bear specific operation and conservation conditions, but the common thing is to attain and remain at the targeted energy product position for a long time. Sustainability is an important element of continued energy product at geothermal power systems, because there are numerous thermodynamic conditions that bear nonstop control during the power product period. Icing sustainability in geothermal power shops consists of two main stages sustainability of geothermal budgets and sustainability of the power factory. For force protection, well optimization, reinjection, force pressure control and mineral scaling are critical parameters, while controlling face outfit and face outfit – fluid relations are important to continued energy product and therefore the sustainability of the power factory [1].

Sustainability of geothermal budgets

Geothermal budgets can be classified as water- dominated or brume- dominated, and both types of systems are suitable for electricity product in high-temperature geothermal systems. A geothermal force may be likened to a vehicle’s gas tank As long as there's energy in the tank, the vehicle keeps running, and when there's no energy in the tank, it stops in a moment [2]. Long- term geothermal power generation also requires the nonstop product of geothermal fluids, and it can only apply an effective product script at the morning of the commissioning of the factory.

Geothermal force systems are controlled by fractures and cracks, and these fracture systems can be linked by some models, similar as the separate fracture network (DFN), in the field of force engineering. Natural water recharge has generally not been enough by itself to feed the geothermal force, and force performance, heat recovery, well distribution and reinjection are also critical parameters during the long power product period. In addition to the product phase, the waste hot or condensed water must be fitted to the reinjection area after brume product to give sustainability in water-or brume- dominated budgets. At the first phase of the feasibility study, during the assessment of geothermal budgets, the conditions of product must be estimated, as must the conditions of reinjection. During the reinjection operation, geothermal fluids are exposed to a series of thermodynamic changes, similar as temperature and pressure, after the separation systems, so the operation must be controlled by hydro geochemistry to understand the changing of geothermal fluids in its path.

Resource and force assessment styles have been examined grounded on the literal or single- point data for geothermal fields. Reservoir threat operation may be classified as disquisition and operation pitfalls at geothermal budgets [3].

The reinjection of non-condensable feasts into geothermal budgets can be a good option to drop hothouse gas emigrations similar as CO2 and H2S, while guarding the force pressure and potentially adding the permeability of the force at depth. Some geothermal emigration abatement styles that may help to increase force pressure after a long product period in a geothermal field have been bandied by experimenters. Some of these experimenters have tried to model absorbing H2S and CO2 by a packed immersion column in water under high- pressure conditions. The other approach is to mix noncondensable feasts and water at different proportions and shoot them to the reinjection wells. New approaches similar as artificial neural networks have begun to be used for reinjection well placement

Geothermal mineral scaling is another problem that directly affects fluid product in water- dominated budgets. The fluids correspond of largely mineralized hot water, brume and non-condensable rudiments, and when total pressure is measured as lower than P gas P liquid, the boiling process begins, and some minerals in the fluids after the release of dissolved feasts similar as calcite and alumina silicates precipitate in boreholes [4]. Geothermal budgets have dynamic thermodynamic conditions and bear nonstop hydro geochemical monitoring, and to break mineral rush problems, chemical inhibition systems are used in each font in a geothermal field.

Sustainability of geothermal power shops

A number of power technologies have been developed for geothermal power product, similar as the double organic Rankin cycle (ORC), flash cycle, multi-flash and advanced ( flash binary) systems, dry brume and hot dry gemstone (HDR) system grounded on geothermal force types for medium-high temperature systems [5].

The sustainability of geothermal power shops generally depends on brume quality and the harmony of geothermal fluid and outfit, in addition to geothermal fluid product. Mineral scaling due to the pressure and temperature of geothermal fluids and erosion due to high non-condensable gas goods are the main functional problems for outfit at the power factory.
