Most countries that burn coal – the planet’s dirtiest fossil fuel by far – usually source it from far beyond their own shores, adding even more transport emissions to those released upon combustion.
Two prominent examples: South Korea orders 90% of its coal from overseas, while Japan imports 99% of it, with the bulk of supply for both countries coming mostly from Australia.
Depending on the logistics of procuring, exporting and combustion, it is estimated that burning PKS instead of coal could slash emissions of carbon dioxide, nitrogen oxide, and sulphur oxide by a minimum of 75%!
As evidence of PKS’s ever-increasing acceptance as a cleaner, greener alternative to coal, they are burned for utility-scale power production mainly in Singapore, Japan, and South Korea.
JAPAN
The Japanese government pays a Feed-in Tariff (FiT) for PKS-enabled electricity, deeming it a type of renewable energy. Under the FiT scheme, electric power companies are required to buy power generated by companies and households using renewable energy sources, at fixed rates for periods as long as 20 years.
SOUTH KOREA
In South Korea, the Renewable Portfolio Standard (RPS) has replaced the FiT system in order to accelerate the country’s renewable energy deployment so as to create a competitive market environment for the sector. Power producers participating in the RPS system receive a certain amount of Renewable Energy Certificates (RECs) – power generated from PKS qualifies for RECs.
