A hydrogen energy system and prospects for reducing emissions of fossil fuels pollutants in the Ceará state—Brazil
Abstract: A model of a solar–wind hydrogen energy system was applied to the Ceará 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 Ceará 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 Ceará state by the year 2060 in both scenarios of hydrogen introduction.
Keywords: Hydrogen energy; Fossil fuels pollutants; Ceará state
Key Variables: electric energy for desalination, fossil fuel price, hydrogen price, energy consumption/demand, gross product, hydrogen production (consumption) rate, quality of life, pollution, population, fossil fuel resources, solar insolation, fossil fuel pollution per unit energy, fraction of fossil fuels extracted per year, ratio of pollution produced by hydrogen to that produced by fossil fuels, ratio of hydrogen utilization efficiency to that of fossil fuels, Emissions of carbon dioxide in the Ceará state, Emissions of methane, Emissions of sulphur oxide, Emissions of nitrogen oxide

Environmental Valuation & Cost-Benefit News
Environmental Valuation & Cost Benefit News covers legal, academic, and regulatory developments pertaining to the valuation of environmental amenities and disamenities, such as clean air, trees, parks, congestion, and noise. We apprise the reader about ways in which costs and benefits are measured, and the results of empirical studies. We hope that this information will allow public and private organizations to comprehend the risks and benefits of various actions, help disputants to resolve conflicts equitably and efficiently, and improve the quality of public policies. We will only discuss issues related to the empirical quantification of private and social costs and benefits and damages, and summarize information from daily newspapers, academic journals, legal publications, court decisions, professional newsletters commissioned studies, and on-line services. This newsletter is dedicated to the principal that all policies place values upon life, liberty, and the pursuit of happiness. We believe that more information, explicit specification of assumptions, and rigorous analysis can help our society to better meet these ends. This site will increasingly serve, in conjunction with others, as a valuation database. We will include a wide range of studies, including non-environmental reports, because omission of a factor effectively values it at zero, and biases decisions. Heavy traffic has caused several site crashes. We are attempting to correct these problems. Apologies for any inconvenience.
