In Situ Geothermal Energy Technology: an Approach for Building Cleaner And Greener Environment

Hossain M. F.

Geothermal energy is abundant everywhere in the world. It certainly would be a great benefit for human being once it is produced by a sophisticated technology. Consequently, it would be the biggest console for earth considering environmental sustainability. Unfortunately, the current status of commercial production of geothermal energy primarily from hydrothermal, geopressured, hot dry rock, and magma are limited to a few countries due to technological difficulties and production cost. This paper describes a simple technology where an in situ geothermal plant assisted by a heat pump would act as a high-temperature production (>150°C) to provide excellent capacity of energy generation. The issue related to costs is interestingly cheaper on production, comparing to other technologies, such as solar, hydro, wind, and traditional geothermal technology as described in this article. Therefore, it is suggested that heat pump assisted in situ geothermal energy sources has a great potentiality to be a prime energy source in near future. Since the technology has a number of positive characteristics (simple, safe, and provides continuous baseload, load following, or peaking capacity) and benign environmental attributes (zero emissions of CO2, SOx, and NOx), it certainly would be an interesting technology in both developed, and developing countries as an attractive option to produce clean energy to confirm a better environment.
