Techno-Economic Comprehensive Review of State-of-the-Art Geothermal and Solar Roadway Energy Systems

Road infrastructure is a vital constituent element in the transportation network; however, roadway surface ice and snow accumulation leads to huge traffic accidents winter. Geothermal energy systems (GRES) solar (SRES) can increase or decrease temperature for de-icing removal of winter, mitigation heat summer. Technology performance economic evaluation GRES SRES are reviewed this paper based on numerical models, experimental analyses. Three crucial aspects technology assessment, i.e., temperature, consumption key factors, explored different regions countries. Economic approaches net present values payback periods investigated. The recommendations potential future developments two technologies deliberated; it demonstrated that could by around 5 °C winter about 6 summer, with 4 8 years 2.3 years, respectively.
