Coal's days are numbered and our future is hydrogen, but this is an evolution: 

The transition will take decades, but in South Korea, hydrogen is already a reality. It has developed a roadmap to build a "hydrogen economy". By 2040, hydrogen gas will account for 5 per cent of its  gross energy. Korea has simultaneously begun to phase out coal and nuclear energy, driven by a national plan to captivate investment and provide renewable energy for its households and industry that by 2030 will account for 20 per cent of total electricity generation.
