Abstract
Coal has been the main energy source in China for a long period. Therefore, the energy industry must improve coal power generation efficiency and achieve near-zero CO2 emissions. Integrated gasification fuel cell (IGFC) systems that combine coal gasification and high-temperature fuel cells, such as solid oxide fuel cells or molten carbonate fuel cells (MCFCs), are proving to be promising for efficient and clean power generation, compared with traditional coal-fired power plants. In 2017, with the support of National Key R&D Program of China, a consortium led by the China Energy Group and including 12 institutions was formed to develop the advanced IGFC technology with near-zero CO2 emissions. The objectives of this project include understanding the performance of an IGFC power generation system under different operating conditions, designing master system principles for engineering optimization, developing key technologies and intellectual property portfolios, setting up supply chains for key materials and equipment, and operating the first megawatt IGFC demonstration system with near-zero CO2 emission, in early 2022. In this paper, the main developments and projections pertaining to the IGFC project are highlighted.
Highlights
Coal is the most abundant and low-cost energy carrier on the planet
Integrated gasification combined cycle (IGCC) power generation systems were designed for higher efficiency and lower CO2 emissions
In July 2017, the China Energy Group received an award from the Ministry of Science and Technology under the National Key R&D Program for a program to develop ‘‘Integrated gasification fuel cell technology with near-zero CO2 emission.’’ To complete this project, an industry–university research team was formed, led by the China Energy Group, and including a total of 12 universities, research institutes, and industrial partners, such as the China University of Mining and Technology-Beijing, the China Huaneng Group, and the National Institute of Clean and Low-Carbon Energy
Summary
Coal is the most abundant and low-cost energy carrier on the planet. This makes coal the dominant source for energy as well as greenhouse gas emissions (Wang et al 2015; Chang et al 2016; Li et al 2018). In July 2017, the China Energy Group received an award from the Ministry of Science and Technology under the National Key R&D Program for a program to develop ‘‘Integrated gasification fuel cell technology with near-zero CO2 emission.’’ To complete this project, an industry–university research team was formed, led by the China Energy Group, and including a total of 12 universities, research institutes, and industrial partners, such as the China University of Mining and Technology-Beijing, the China Huaneng Group, and the National Institute of Clean and Low-Carbon Energy. The team has been focusing on key scientific problems and technologies related to IGFCs, such as coal gasification techniques, syngas cleaning processes, high-temperature fuel cell stack and module design, fuel cell system integration and design concepts, and CO2 capture and utilization This team is technology innovation-oriented, and the objective of the project is to develop an IGFC technology that can be scaled up for 500 kW system demonstration. Traditional coal-fired power plants can be replaced by efficient 100 MW IGFC power generation systems with near-zero carbon emissions
