Lignite and hard coal: Energy suppliers for world needs until the year 2100 — An outlook

Abstract

Abstract For three years, international hard coal prices have been at rather expensive levels. Some argue that these higher prices might indicate the threat of a physical scarcity of fossil fuels — similar to the situation with oil and gas. This is not true. The supply situations with lignite and hard coal appear to be largely not critical. Adjusted to the rise in global coal consumption, which is expected until 2100, nature by and large can meet the world's coal demand. This is shown for lignite in this article and it is illustrated for hard coal here, differentiated in space and time for a world divided into eight regions and viewed for the years 2005, 2020, 2030, 2050, and 2100. The only area of potential concern is Asia (especially China). But today's and coming eager efforts in China to convert coal resources into reserves will most likely deliver the coal needed for the Chinese market. Up to the year 2100, and from a geoscientific point of view, there will be no bottleneck in coal supplies on this planet.
