The current issue of the scientific journal Energy contains “A global coal production forecast with multi-Hubbert cycle analysis,” by Tad Patzek and Gregory Croft which discusses the latest research on coal reserves. Based on scientific modeling, global coal production is expected to peak in 2011, which does not mean that coal will run out, but that economically-feasible, easily reached coal will run out. Carbon dioxide emissions related to coal burning are also expected to peak in 2011 and decline as production of coal declines.
Key findings from the study include:
1. Global coal production is likely to peak in the year
2. The global CO2 emissions from coal will also peak in 2011,
3. The estimated CO2 emissions from global coal production will
decrease by 50% by the year 2050
4. Between the years 2011 and 2050, the average rate of decline of
CO2 emissions from the peak is 2% per year, and this decline
increases to 4% per year thereafter
5. It may make sense to have carbon capture and sequestration
(CCS) to alleviate the highest CO2 emissions between now and
the year 2020 or so.
