Energy sources as a research area encompasses the systematic study, characterization, and optimization of primary and secondary forms of energy supply, including fossil, nuclear, and renewable resources, with emphasis on conversion efficiency, environmental impact, resource availability, and systems integration. It spans fundamental and applied work on solar, wind, hydro, geothermal, bioenergy, and emerging options such as hydrogen and advanced nuclear, as well as storage-coupled and hybrid systems. Research typically addresses thermodynamic limits, materials and device performance, lifecycle assessment, techno-economic analysis, grid integration, and policy-relevant modeling to enable reliable, scalable, and low-carbon energy provision.
As a combustible fuel, the burning of hydrogen gas does not contribute to global warming. Today, the majority of hydrogen gas is generated from fossil fuels, however, and this process releases greenhouse gases into the atmosphere. ...
