“…In pre-combustion processes, hydrocarbon fuels are converted to a mixture of hydrogen and CO 2 (via gasification or reforming combined with the water-gas shift reaction) and the CO 2 separated from hydrogen, the latter being used as fuel for power generation (70). Integrated gasification combined cycle (IGCC) plants equipped with CO 2 capture, such as the Kemper County Energy Facility in the United States (582 MW), are one example of this process.…”

We review future global demand for electricity and major technologies positioned to supply it with minimal greenhouse gas (GHG) emissions: renewables (wind, solar, water, geothermal, and biomass), nuclear fission, and fossil power with CO2 capture and sequestration. We discuss two breakthrough technologies (space solar power and nuclear fusion) as exciting but uncertain additional options for low-net GHG emissions (i.e., low-carbon) electricity generation. In addition, we discuss grid integration technologies (monitoring and forecasting of transmission and distribution systems, demand-side load management, energy storage, and load balancing with low-carbon fuel substitutes). For each topic, recent historical trends and future prospects are reviewed, along with technical challenges, costs, and other issues as appropriate. Although no technology represents an ideal solution, their strengths can be enhanced by deployment in combination, along with grid integration that forms a critical set of enabling technologies to assure a reliable and robust future low-carbon electricity system.

“…Following a CO 2 separation unit is definitely required to separate CO 2 from the WGS produced gas, which is based on different configurations considered in practical operation; for instance in NGCC-PRE process, chemical absorption is generally adopted applying MEA or MDEA solvent [21,23,24]. In this work, MDEA solvent is considered as CO 2 -acceptor ascribe by its outstanding advantages in comparison with MEA solvent, such as less heat load for regeneration, lower corrosion and degradability, and higher separated CO 2 concentration [25].…”

Summary In this work, three kinds of natural gas‐based power generation processes for CO2 capture and storage, that is, natural gas‐combined cycle with pre‐combustion decarburization (NGCC‐PRE), NGCC‐PRE with calcium‐looping process, and NGCC‐PRE with chemical‐looping combustion (NGCC‐CLC), are analyzed by Aspen Plus. The effects of two decisive variables (i.e., steam‐to‐natural gas (S/NG) ratio and oxygen‐to‐natural gas (O/NG) ratio) on the thermodynamic performances of individual process, such as energy and exergy efficiencies, are investigated systematically. Based on simulation outcomes, all the three processes are favored by operating at S/NG = 2.0 and O/NG = 0.65. Furthermore, comparisons of individual system efficiencies and exergy destruction contributor are herein involved. The results show that the highest system efficiencies and lowest exergy destruction are achieved in the NGCC‐CLC process. In addition, capital investment, dynamic payback period, net present value, and internal rate of return are used for deciding the economic feasibility and surely are involved in this work for comparison purpose.

“…solar and wind) will deeply modify the energy market and, accordingly, the capacity of efficient operation at part-load will become essential for thermal power plants. Integrated Gasification Combined Cycle (IGCC) seems to be attractive for capturing CO2 [6]. The high pressure at which the CO2 separation can be carried out helps limiting the energy penalty.…”

The coproduction of power and ultrapure H2 within an integrated gasification combined cycle (IGCC) plant implementing CO2 capture offers advantages in terms of flexible operation while retaining good efficiency. The common design includes an absorption unit for removing CO2 from a high pressure syngas followed by a pressure swing adsorption (PSA) unit for purifying a part of the resulting H2-rich gas stream. A drawback of this design consists in the necessity for compression of the PSA tail gas in order to recover the energy available in the residual H2 content. This paper presents two novel configurations for power and H2 coproduction with CO2 capture, entirely based on PSA technology. The first relies on two PSA trains in series (Two-train PSA), while the other is able to carry out CO2 separation and H2 purification within a single PSA train (One-train PSA). The two systems were defined and simulated through a composite model of the whole plant. The process simulation results showed that both the configurations proposed are able to shift between the two energy products without compromising the performance of the plant. The load of the plant could be decreased by increasing the ultrapure H2 throughput, while maintaining a constant feed of coal to the gasifier. The Two-train PSA configuration achieved higher performance in terms of energy efficiency and H2 purity. The One-train PSA configuration returned slightly lower but still good performance, while its design includes a single separation stage instead of two. Additionally, both configurations enable the avoidance of PSA tail gas compression giving an advantage against the absorption-based design. A comparative analysis with results taken from the literature seems to confirm this assertion.
