Lignite is the coal with the lowest cost and as well the lowest energy/weight. It contains a lot of humidity and hydrogen. Lignite was the main source to produce fuel in ww2 in Germany. Since then plenty of test reactors CTL and CTG were built and run. The most sucessful plants are run by SASOL. Other similar plants are the GTL plants in Khatar run by Shell and others.

$7.5 billion Kemper power plant suspends coal gasification

Apparently they've given up on the gasification plant and plan on running natural gas only now. If they had done more intermediate gasification plant prototyping rather than doing doing the small scale tests then commit to full size hardware in one go and fix it on the fly (what is this sick concurrent dev mindset that has infected US engineering, like the F-35 fighter), the outcome might have been different if a bit more drawn out.

With the coal handling system being effectively incomplete, that removes yet another chance to gain full scale ops experience with coal gasifiers within the US, which hampers CTL dev and deployment. The TRIG gasifier itself may have been a hot mess of a choice however, regardless of the coal feed system issues.

Though the root cause smells like an over aggressive schedule fueled by dreams of accelerated short term profits if completed.

Underground gasification of low/marginal quality coal may be the most cost-effective way to synthetic fuels. Use of nuclear steam as heat could cut the carbon dioxide creation. Conversion of syngas to light fuels ethanol/methanol/dme will avoid particulate matter on burning.
Once developed, it could be adopted as the standard coal usage.
Such fuel could be used for ICEs but could be evolved to fuel cells too. Syngas could be used directly as piped gas fuel.

Official announcement:

Southern Company and Mississippi Power announce suspension of gasification operations

Quote:
Southern Company and Mississippi Power today announced the company is immediately suspending start-up and operations activities involving the lignite gasification portion of the Kemper County energy facility. The combined cycle plant has been serving customers with reliable and affordable electricity for almost three years. The facility will continue to operate using natural gas pending the Mississippi Public Service Commission’s decision on future operations. This action is being taken to preserve the safety and health of the workforce and safety of the facility, while still retaining the necessary workforce to operate the combined cycle power plant. “We are committed to ensuring the ongoing focus and safety of employees while we consider the future of the project, including any possible actions that may be taken by the Commission,” said Southern Company Chairman, President and CEO Thomas A. Fanning. “We believe this decision is in the best interests of our employees, customers, investors and all other stakeholders.” Southern Company and Mississippi Power believe this is the appropriate step to manage costs given the economics of the project and the Commission’s intent to establish a settlement docket to address Kemper-related matters including the future operation of the gasifier portion of the project.


This is a bitter end for this money-draining project. It along with Vogtle has taken away much of the ambition that Southern Company had for new and advanced projects at the start of this decade.

Chemical plants have scary accidents as in Bhopal in India in a US owned Union Carbide plant. We live and learn.
