low to near zero co2 production of hydrogen from Fossil Fuels status and perspectives
International Journal of Hydrogen Energy, 2017Co-Authors: Nazim MuradovAbstract:Abstract At present, practically all industrial production of hydrogen either directly or indirectly (e.g., through electricity generation) relies on Fossil Fuels (mostly, natural gas and coal) and, according to many projections, this trend will continue in the foreseeable future. As a result, hydrogen plants are and will remain a major source of CO2 emissions to the atmosphere, with potentially adverse consequences to our planet's ecosphere and climate. In view of these negative trends, there is an urgent need to substantially reduce or even completely eliminate CO2 emissions from Fossil fuel-based hydrogen production processes in order to underscore environmental advantages of hydrogen as an ecologically clean fuel. The main technological approaches to low to near-zero CO2 production of hydrogen from Fossil Fuels can be classified into three main groups: (1) coupling hydrogen plants with CO2 capture and storage systems, (2) dissociation of hydrocarbons to hydrogen and carbon, and (3) integrating hydrogen production processes with non-carbon energy sources such as nuclear and solar energy. The objective of this paper is to overview and analyze the current status of existing and emerging technological options and solutions to drastically reducing the amount of CO2 emissions from Fossil fuel-based hydrogen manufacturing plants. A near-to-mid term outlook for low to near-zero CO2 hydrogen production from Fossil Fuels in the light of new technological trends is examined in this paper.

Low-carbon production of hydrogen from Fossil Fuels
Compendium of Hydrogen Energy, 2015Co-Authors: Nazim MuradovAbstract:Currently, practically all industrial manufacturing of hydrogen is based on Fossil Fuels. However, even the “cleanest” of H2 production processes, steam methane reforming, produces close to 10kg CO2 per kilogram of H2 product. This fact may diminish the environmental appeal of hydrogen as an environmentally clean fuel. Thus, there is an urgent need to develop and implement Fossil fuel-based hydrogen production processes with low-to-zero CO2 emissions. The objective of this chapter is to analyze existing and emerging technological options and solutions for eliminating or drastically reducing the amount of CO2 emissions from Fossil fuel-based manufacturing of hydrogen. The main approaches to low-carbon production of hydrogen from Fossil Fuels discussed in this chapter include: (1) integration of Fossil fuel-based hydrogen plants with CO2 capture and storage, (2) production of CO2-free hydrogen via dissociation of methane, and (3) the combination of Fossil fuel-based hydrogen production processes with noncarbon energy sources such as nuclear and solar. Current status, emerging technological trends, and outlook for low-carbon production of hydrogen are analyzed in this chapter.

Hydrogen from Fossil Fuels without Co2 Emissions
Advances in Hydrogen Energy, 1Co-Authors: Nazim MuradovAbstract:In the nearto medium-term future, hydrogen production will continue to rely on Fossil Fuels, primarily natural gas (NG). It is generally understood that the renewable energy-based processes of hydrogen production (photoelectrochemical and photobiological decomposition of water, solar-photovoltaic water electrolysis, thermochemical and hybrid water splitting cycles, etc.) would unlikely yield significant reduction in hydrogen costs in the next 1-2 decades. The future of nuclear power systems, a relatively clean and abundant energy source, still remains uncertain due to strong public opposition. In general, given the advantages inherent in Fossil Fuels such as their availability, cost-competitiveness, convenience of storage and transportation, they are likely to play a major role in global energy supply for the next century. On the other hand, Fossil Fuels are major source of anthropogenic CO2 emissions to the atmosphere. Various scenarios of global energy use in the next century predict a continued increase in CO2 emissions that would gradually rise its concentration in the atmosphere to dangerous levels. It is clear that the industrialized world would not be able to retain present living standards and meet challenges of global warming, unless major changes are made in the way we produce energy, and manage carbon emissions. There are several possible ways to mitigate CO2 emission problems. Among them are traditional approaches including: (i) more efficient use of Fossil fuel energy resources, (ii) increased use of clean Fossil Fuels, such as NG, and (iii) increased use of non-Fossil Fuels (nuclear power and renewable sources). The novel and most radical approach to effectively manage carbon emissions is the decarbonization of Fossil Fuels. Three main scenarios of Fossil Fuels decarbonization are currently discussed in the literature:

a hydrogen energy system and prospects for reducing emissions of Fossil Fuels pollutants in the ceara state brazil
International Journal of Hydrogen Energy, 2008Co-Authors: E. M. Do Sacramento, L.c. De Lima, Celso J.b. Oliveira, Nejat T VezirogluAbstract:Abstract A model of a solar–wind hydrogen energy system was applied to the Ceara state—Brazil and the prospects for reducing emissions of Fossil Fuels pollutants in such federal state were studied. This long-term study simulates three scenarios of fast, slow and no introduction of hydrogen in the energy balance of the Ceara state. Not including nitrogen oxides, if fuel burning continues, results indicate that hydrogen energy eventually will reduce to zero all emissions of Fossil Fuels pollutants in the Ceara state by the year 2060 in both scenarios of hydrogen introduction.
