Abstract: A potential enabler of a low carbon economy is the energy vector ammonia, which is a carbon free carrier with high energy density. Hence, it is proposed that ammonia, with its established transportation network and high flexibility, could provide a practical next generation system for energy transportation, storage and use for power generation. Therefore, previous studies and ongoing research are presented to use this chemical as a viable energy vector for power applications, emphasizing the challenges before implementation and commercial deployment is achieved at a larger scale. The talk covers fundamental research results on ammonia combustion are presented including ignition delay times, laminar flame speeds, species concentration profiles, oxidation chemistry, laminar and turbulent flames structures. Ammonia flame stabilization behaviors and emission characteristics are presented and discussed by using a gas turbine combustor. Injection and co-firing strategy in swirl combustors and the combustion enhancement will also be addressed. A better understanding on emission controls over the combustion on NOx mitigation and other techniques will be revealed.

Abstract: Conventional energy sources including oil, gas, and coal are supportive to the socio-economic system of the modern world, but injurious to the human health and the climate. The present global energy account shows 26% contribution by the renewables and 74% by the fossil fuel. The futuristic scientists, researchers and investors are thinking wisely to making all-out their efforts in harnessing the renewable energy sources (Solar, Wind, Hydro, Nuclear). The projects on alternate energy or green energy were activated, got strong conceptual grip, turned into commercial business growth, but unfortunately the upward growing graph was hurdled by COVID-19. Under the impact of Climate Change and Industrial growth, it is needed to strengthen and expand the scope of operationalization of renewable energy projects. This study presents comprehensive literature on White hydrogen which is an innovative energy source. It is aimed to enhance the domain of sustainable energy resources (biomass, geothermal, solar, hydro, wind, and biofuel) and their integrated products may be explored. White hydrogen which emerged incidentally from earth (2016) from Mali area, later discoveries from US, eastern Europe, Russia, Australia, Serbia, France, Oman, are considered to be a potential futuristic revolutionary innovative energy source. Calculations and speculation suggest that tens of billions of tons of hydrogen is present in the earth’s crust. On the other hand, the energy efficiency of hydrogen has been observed as double of the gasoline engine. On the basis of efficiency, pollutant free, and naturally available, the Geological Society of America forecast that the demand for hydrogen would go quintuple by 2050. This study concludes a plausible explanation on white hydrogen, its exploration and commercial use as renewable energy source.
