Study on new trends in enhanced, hybrid and integrated geothermal systems

The most important challenge for the global energy sector is to rapidly transform the entire system to one less dependent on fossil fuels and so reduce the harmful effects on the climate. In sharp contrast, the global energy demand, mainly being met by fossil fuel resources, is continuing to grow, primarily in response to population and economic growth. Therefore, finding, developing, and utilizing effective, economical, and practical solutions to the ongoing and emerging challenges is essential.

Meeting the global energy demand and simultaneously minimizing the negative consequences of climate change and the threat of global warming requires a transition to energy systems largely based on noncarbon renewable energy sources (e.g., solar, wind, geothermal, and hydro). Geothermal energy installations—shallow, deep, or a combination of both—provide sustainable and environmentally friendly energy. Exploiting this source consists of extracting and/or storing the Earth’s thermal energy for use in meeting electricity and heating/cooling needs for a variety of applications, including to heat and cool dwellings and greenhouses, provide warm and/or cold water for agricultural products in greenhouses, and even to de-ice roadways and parking areas.

The main goal of this Special Issue has been to address the existing knowledge gaps and help advance the deployment of geothermal energy projects worldwide. Of the twelve articles submitted, eight were accepted for publication after the peer-review process, an acceptance rate of ~67 percent. The published articles, briefly described in the following section, cover a range of topics and applications central to geothermal energy.
