The research discusses making coal cleaner by using advanced technologies to reduce harmful emissions when burning coal. Both China and the United States are focusing on developing ways to use coal more cleanly for producing power and chemicals. The U.S. has been a leader in cleaner coal technologies, but now China is also investing heavily in this area. Despite challenges like lower natural gas prices and environmental concerns, coal is still expected to be a significant part of the global energy mix. The research highlights the importance of advancing coal gasification technology to make coal a more environmentally friendly energy source for the future.
