A novel methanol-based power system with Chemical-Looping Combustion (CLC) is proposed in this paper. CLC system is a promising approach to greatly decrease the energy penalty for CO2 removal, where iron oxides circulate between two reactors and an inherent CO2 separation occurs. The combustion...

The energy saving mechanism and the potential of efficiency improvement for coal to synthetic/substitute natural gas and power plant with different schemes and CO2 capture is disclosed through exergy analysis, and the effects of key parameters on exergy losses and system performance are...

The broadly applicable equations for estimating learning rates of cost variables in energy systems with CO2 capture (CC) are formulated, in which the effect of overall plant efficiency upgrade on learning rates is reflected. Based on the equations, as a case study, we estimate the learning...

Recently, interest in chemical-looping combustion (CLC) has grown because it is a technique that could allow cost-effective carbon capture and storage. Recently, the chemical-looping process was also proposed for the production of hydrogen. Chemical-looping hydrogen (CLH) generation, which is a...

The coal based polygeneration with CO2 capture (PG + CC) technology is expected as one of the possible options to mitigate CO2 emissions with low cost and low energy. This work assesses the cost reduction potential of PG + CC technology based on learning curve method, and finds out what...

For both energy security and CO2 emission reduction, synthetic natural gas (SNG) production from coal is an important path to implement clean coal technologies in China. In this paper, an overview of the progress of coal to SNG technologies, including the development of catalysts, reactor...

This paper proposes a polygeneration system based on a multi-input chemical looping combustion system, which generates methanol and electricity, through the use of natural gas and coal. In this system, the chemical looping hydrogen (CLH) production system and the coal-based methanol production...

Reviewing the progress of CO2 capture and storage (CCS) technology, the main obstacles and the potentials of greenhouse gas control in China are identified. An important point can be drawn is that the innovative energy systems, besides simple implementation of existing technology, are needed for...

In this paper, a novel combined cycle with synthetic utilization of coal and natural gas is proposed, in which the burning of coal provides thermal energy to the methane/steam reforming reaction. The syngas fuel, generated by the reforming reaction, is directly provided to the gas turbine as...

The distribution of energy and industry in China is extremely uneven. The western region is rich in energy resources but relatively economically backward, while the eastern region, particularly, the southeast coastal area, is an industrially-developed area but is short of energy resources. On...
