Description

Novel comprehensive system for hydrogen production and power generation through carbon dioxide decomposition based on seawater
Technical Field
The invention relates to a novel comprehensive system for power generation by decomposing carbon dioxide to produce hydrogen based on seawater.
Background
Carbon dioxide is one of the greatest causes of global warming. Because carbon dioxide has the function of keeping warm, the temperature of the earth surface is gradually increased. In the last 100 years, the global temperature rises by 0.6 ℃, and as such, the global temperature is expected to rise by 1.5-4.5 ℃ by the middle of the 21 st century. The rise of sea level caused by greenhouse effect also has great influence on the living environment of human beings. The ice cubes of the bipolar ocean will also melt completely. All these changes were no different from a disaster of extinction for wild animals. By 2013, 5 months, the concentration of carbon dioxide in the earth's atmosphere has exceeded 400ppm (400 parts per million). The rate of increase in concentration between 2000 and 2009 is 2.0ppm per year and accelerates year by year. The concentration at present is much higher than the 280ppm concentration before industrialization, and human factors are the main reasons for the sharp rise of the carbon dioxide concentration. Of the released carbon dioxide, 57% enters the atmosphere and the remainder enters the ocean, causing acidification of the ocean.
The existing power grid system is difficult to meet the requirement of large-scale grid-connected consumption of renewable energy, and the problems of wind abandoning, water abandoning and light abandoning in partial areas caused by power grid constraint are serious. The electricity and light abandonment in 2018 is about 691 hundred million kilowatt hours, 277 million kilowatt hours and 54.9 million kilowatt hours. In addition, the substitution cost of replacing coal with gas and replacing coal with electricity is high, the optimal configuration of clean energy sources in the whole country is hindered, the conditions of heavy construction and light utilization are prominent, the supply and the demand are unbalanced and uncoordinated, and the proportion of renewable energy sources in primary energy consumption is still lower compared with the proportion of the renewable energy sources in advanced countries.
Among all the energy sources known at present, hydrogen energy is the cleanest energy source, and the product in the use process of hydrogen gas is water, so that zero emission and no pollution can be really realized, the hydrogen energy is regarded as one of the most promising energy sources, and is also regarded as the ultimate form of energy source use by some people. The electric energy converted from photovoltaic power, wind power and water power is very fragile as an invisible and untouchable energy medium, and the storage and transportation of the electric energy are more difficult to realize than the actual fossil fuel. The conversion of uncontrollable electrical energy into a chemical energy carrier that is as easy to store and transport as fossil fuels is an urgent need. The hydrogen energy is regarded as an optimal way, and can be produced by renewable energy sources such as solar energy, wind energy and the like, and carbon dioxide is not generated when the hydrogen energy is used. As long as the technical difficulties of storage conditions and transportation are solved, the hydrogen energy can be conveniently and efficiently converted into heat energy or electric energy.
