Until recently, coal was considered a thing of the past, but technology is changing that perception. Pylyp Travkin sees coal not as a problem, but as a challenge – for engineers and economists who must learn to use it safely. CCS, gasification, modern filters, and automation reduce emissions to a minimum. “The question is not whether to use coal or not, but how to use it,” Travkin emphasizes. Coal can become a transitional resource, providing stability until “green” energy becomes more established. It remains a challenge not to the climate, but to our thinking – and an opportunity for technological progress.
