Green energy that does not emit CO2 and other greenhouse gases, one that replaces heating with fossil fuels. It is ALSO ideal for your company’s heating development aimed at getting greener.
Emission-free and carbon-neutral
Due to the closed loop system, gas production known from other deep geothermal systems does NOT occur here with the extraction of thermal water. Unhealthy combustion products, gases are not produced or extracted either. No extracted or generated by-products have to be disposed of, that is why simpler machinery solutions are used. Simple solutions are the features of the convenient and user-friendly system. Running expenses and maintenance costs are negligible.
Not harmful to the environment
The operation of the closed loop system does not harm the environment, causes no O&G, hence it does not affect the underground water. Thermal water reserves are finite, and underground water flows are sensitive! A wasteful extraction where there is no re-injection does not comply with the principles of sustainability of geothermal energy utilization! Closed loop water circulation has a smaller energy volume, but, on the other hand, it does not affect the vulnerable system of underground thermal waters, either with regard to quality or quantity.
Sustainable and self-regulating
Operation of WeHEAT systems is limited to the normal geological frames of sustainability. The heat transportation processes of the geological environment can be utilized, but cannot be overproduced. The sustainable production scale is set through transient modeling, so the depth system can be exploited only up to the maximum of the renewal scale. It makes stable and long-term productivity possible in such a self-regulating way.
REUSE OF ABANDONED DEEP DRILLINGS
Most of the deep-drilled wells in Hungary that are deeper than 1800 m were established to extract some kind of raw material. These wells are used as long as they operate efficiently. As the raw material is further and further produced, the deep wells of the depleted fields are abandoned, production is discontinued and the wells are closed. Thus, the structure of both dry holes and depleted wells is left without any functions. The highest cost element of geothermal investments is reaching the heat sources, that is, implementation of the drilling(s) and deep drilling(s). When using an unused deep drilling, this element can be reduced and replaced by a well evaluation / well completion task, which has a cost that is lower by an order of magnitude.
Temperature rises by 30 deg.C on average with every kilometer when moving down towards the center of the Earth. In Hungary, this rate reaches an average of as much as 50-60 deg.C; therefore, at the depth of 2 km the average temperature is often higher than 100 degrees. Besides that, heat transfer is a lot faster in the underground aquifers than in nonpermeable formations. The Pannonian age sedimentary layers ensure the proper level of heat flow. The WeHEAT technology utilizes, among others, Hungary’s outstanding geothermal gradient and its unique geological environment that involves rich saturated water supplies.
GEOTHERMAL ENERGY - FOR HEATING AND HOT WATER
Taking domestic geothermal conditions into consideration, the most efficient use of the geothermal heat is direct heating of buildings and supply of hot water. In this case, the extracted heat can be fully utilized, and in case of a closed loop system, its temperature can be maintained in the highest temperature range. The efficiency of the system is very high, and it decreases by only a few percent when heat exchanger(s) is/are used, or if the system is segmented. The WeHEAT systems are especially suitable for local heat demands, but also for institutional size heating needs.
