Some cyclic molecules have been proposed as liquid-organic hydrogen carriers (LOHC) due to their ability undergo dehydrogenation reversibly, with ones containing nitrogen in the ring showing special stability. Here, we examined one of these, 1,2,3,4-tetrahydroquinoline (THQ), for use an endothermic fuel thermal protection hypersonic aircraft engines. The conversion and heats reaction were measu...

The world is presently confronted with the twin crises of fossil fuel depletion and environmental degradation. The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in the present context. The fuels of bio-origin can provide a feasible solution to this wo...

As the demand for alternative fuels to solve environmental problems increases worldwide due greenhouse gas problem, this study predicted liquid hydrogen fuel in aviation achieve ‘zero-emission flight’. The models of an aircraft and all sectors were produced based on prediction fleet growth through classification currently operated aircraft. Using these models, required amount total cost also ca...

We investigate the economics of coal-to-liquid (CTL) conversion, a polygeneration technology that produces liquid fuels, chemicals, and electricity by coal gasification and Fischer–Tropsch process. CTL is more expensive than extant technologies when producing the same bundle of output. In addition, the significant carbon footprint of CTL may raise environmental concerns. However, as petroleum p...

Fossil fuels depletion and increasing environmental impacts arising from their use call for seeking growing supplies from renewable and nuclear primary energy sources. However, it is necessary to simultaneously attend to both the electrical power needs and the specificities of the transport and industrial sector requirements. A major question posed by the shift away from traditional fossil fuel...
