Abstract
The current dependence on fossil fuel power generation and its developed infrastructure make fossil fuel still a crucial energy source. However, sustainable power generation is a critical need. The integrated power generation and CO2 utilization process are a power-to-X system for simultaneous power and chemical production. The well-outlined benefits and the flexibility in energy and chemical conversion give this process an encouraging technical and theoretical perspective. This chapter tries to evaluate the concept of polygeneration operation for future power plants with the aim of not only minimizing emission but also sustaining profitability. It is illustrated that by applying a polygeneration configuration, developing the most efficient integration of off-gas pretreatment, utilization of electricity, and chemical production is achievable.
