SUMMARY

The conversion of energy storage from gigawatts per billion cubic feet (GW/bcf) to joules per cubic meter (J/m³) is established through a systematic calculation. Given the storage capacity of 500 GW in 535 billion cubic feet, the energy stored over a half-day period is approximately 2,592,000 J/m³. This calculation utilizes the relationship between watts and joules, where 1 GW equals 1x10^12 watts, and the conversion factor of 1 cubic meter equaling 35.31466672 cubic feet. The importance of considering the time period for energy conversion is emphasized for accurate results.

PREREQUISITES
  • Understanding of energy units: Watts, Joules, and their conversions.
  • Familiarity with volumetric measurements: cubic feet to cubic meters.
  • Basic knowledge of power storage concepts in energy systems.
  • Ability to perform unit conversions and dimensional analysis.
NEXT STEPS
  • Study the principles of energy storage in pressurized systems.
  • Learn about the calculations involved in converting power to energy over time.
  • Explore the implications of energy density in various storage mediums.
  • Investigate advanced energy storage technologies and their efficiency metrics.
USEFUL FOR

1.They claim that it is possible to store over 500 GW of power (presumably for part of a
day) in pressurized caverns of 535 billion cubic feet. If the storage time is one half day,
what is this in Joules per cubic meter?



2.Watt=J/s
GW=1x10^12 Watts
1 cubic meter = 35.31466672 cubic foot



3. 500GW/535 BFC= .934 W/CF=.934j/s/CF=aprox 2592000J/m^3

Im not sure if the solution i worked out was correct or not just wanted to make sure.

You need to take into account the half-day time period, to go from power to energy. Once you figure out how many Joules of energy it takes to generate that power for half of a day, you will be able to them figure out how many Joules per cubic foot of storage that equates to. Don't just write down random combinations of variables trying to divine the answer. Think the problem through step-by-step.
