Project Definition A 500 MW power plant is designed and fueled by natural gas. Chemical Looping technology will be used to produce CO2. This project consists of three parts: a Chemical Looping Combustion, Carbon Dioxide capturing and electricity generation. Electricity and CO2 will be sold as products and H2O will be re-engaged in the process. Electricity is generated from steam turbines. To be a beneficial supplier to Wyoming, Colorado and Utah this plant will be located between Green River and Rock Springs because it is near by several natural gas pipelines and the Green River as a source of water while CO2 is captured and stored. 1.1 Business Opportunities To have a sustainable economy that is environmentally friendly, it is necessary to find a clean, cheap, and abundant energy supply. Chemical looping is an environmentally friendly process, and if the efficiency is high enough, it can be a competitor for other electricity production processes. The projected energy supply through year 2030 will be drawn from oil, coal, natural gas; renewable forms of energy; and nuclear energy, in that order. Competition for the chemical looping process includes traditional combustion processes. Among these, fossil fuels account for more than 86% of the world’s energy supply. For primarily economic reasons, fossil fuels will continue to play a dominant role in the world’s energy supply for the foreseeable future. Natural gas has been a common energy source for heating, electricity generation, and hydrogen production. The price of natural gas varies significantly with locations and source. It is projected that the natural gas price will decrease from $4.44/MMBtu in 2014 to $4.11/MMBtu in 2015 [U.S. Energy Information Administration, 2014]. Despite the projected price decrease, the share of natural gas in world energy consumption is expected to remain at 24% from year 2005 up to 2030 [ Fan,NJ,2010]. 1.2 Key assumptions The effective performance of the chemical looping particles or oxygen carrier particles is important to have a successful operation of chemical looping process. Metal oxide, support, and agent are effective particles of the chemical looping. These particles have to have desired properties in order to be effective ones [Fan, 2010].
