Energy generation system for non-traditional combustible fluid source

An energy generation system comprising:

• a pump configured to move a combustible fluid from a combustible fluid source to a fluid storage system;
• the fluid storage system comprising:
• a compressor,
• a first set of one or more storage tanks, wherein the first set of one or more storage tanks are configured to receive the combustible fluid from the pump and store the combustible fluid at a first pressure, and
• a second set of one or more storage tanks, wherein the compressor is configured to pressurize the combustible fluid from the first set of one or more storage tanks to at least one second pressure for storage in the second set of one or more storage tanks;
• and
• an energy recovery system configured to receive the combustible fluid from the second set of one or more storage tanks, the energy recovery system including:
• an expander configured to produce depressurized combustible fluid by depressurizing the combustible fluid received from the second set of one or more storage tanks, and
• a motor-generator configured to receive the depressurized combustible fluid and generate electrical energy from the depressurized combustible fluid.
