Wind power is being curtailed because large scale electrical energy storage systems are not available. However, a practical, large-scale, electro-thermal in situ energy storage system has been designed. Wind energy via the grid is transferred into unconventional oil deposits, such as the oil shale, tar sand or heavy oil deposits in the USA. This stored heat eventually converts the hydrocarbons into...
The trillion barrel oil shale and oil sand deposits in North America offer the potential to make the less energy dependent on unreliable foreign sources. However, if these unconventional deposits were produced using existing combustion processes, substantial CO2 emissions would be injected into air. To avoid this green house gas problem and yet produce liquid fuels, a wind powered electrothermal...
