There is a growing need for batteries to power electronic systems within the aerospace industry. Interestingly, there is a significant overlap between drilling industry battery requirements and future commercial aircraft. Batteries in the drilling industry do everything from powering sensor systems with wireless communication to driving large motor-controlled valves. Whether the battery powered system is 30,000 ft underground or 30,000ft in the air, the system must work. This paper presents the practical requirements that aerospace battery engineers need to know in order to develop new high-temperature batteries for subterranean wells, both for the oil industry and for geothermal energy generation.

It is well known that the drilling industry is a diverse industry with huge power needs for drilling deep wells. This paper discusses the drilling industry in general and the future need for HT power electronics to enable such activities as tractor drive drilling of deep horizontal wells. The discussion is geared at applications for drilling within the earth at ambient temperatures of 150°C and above.
