Geothermal energy projects showing upward swing (IEA)

 

According to the recent report (2018) published by the International Energy Agency, geothermal energy capacity is set to grow by 28% amounting to 17 GWe by the year 2023. More and more countries are exploiting their untapped sources to reduce carbon dioxide emissions and control the use of fossil based electricity. China alone has shown the largest growth of 2 GW in the last couple of years. Indonesia followed by Kenya are the leaders in expanding their geothermal base, increasing to the tune of 30%. Although pre-development risks are still the barrier for development, such barriers can be overcome by skillful planning and good data interpretation. In addition the drilling cost are showing downward trend due to technological improvement. In future, with the advent of plasma drilling and development of Enhanced Geothermal Systems, growth of this industry will see exponential rise. Low CO2 emissions, baseload power, high efficiency and small lad foot print are some of the factors that is attracting the geothermal sector in several developing countries. Soon this sector will add additional 20% amounting to 900 MW. The main additions are from Kenya ( 180 MW) and Indonesia. Philippines and Turkey will be add another 70 MW. Countries like Japan, England, China, France and Germany have initiated EGS projects that are at different stages of development.  Direct application projects are showing a surge due to technological development in ground source heat pumps.
