The study aims to show how methanol can be made from coal underground to replace petroleum. Scientists have made better ways to turn coal into gas using new technologies like gas turbines. They want to see if the methanol they produce can compete with petroleum in terms of money and performance. Methanol is seen as a good fuel that doesn't harm the environment as much as other fuels. The researchers hope to prove that making methanol from coal underground can be a good alternative to using petroleum.
