SNG As Renewable Energy Transport Media

In recent years, reducing CO2 emission has been the focus for addressing the concern over global warming and presumed related abnormal weather phenomena such as wildfire in California, US and Turkish, serious flooding in US, Europe and China, strong hurricanes, drought, and the melting of the permafrost of Alaska and Siberia and polar ice caps. The natural gas industry has already taken steps to reduce the CO2 emission by using high efficiency gas turbines instead of steam turbine systems. Will these steps be enough to satisfy the ever-increasing social concerns, or will further reductions be required?

To respond the social concern, following ideas are presented:

• Methane, SNG, synthesis: renewable energy, i.e., wind power generation lead to hydrogen production by electrolysis. Methane is synthesized by Sabatier reaction with recycled CO2.
• The SNG is compressed by compressor and transferred by pipeline
• Receiving Terminal and Power Generation: application of high efficiency combined cycle systems, CO2 recovery by amine process from gas turbine exhaust and CO2 is compressed for transport.
• The CO2 is compressed by compressor and transferred by pipeline and recycled to the SNG synthesis.

This concept would lead to higher power costs for the consumer as around 30 cents per kWh, it may look costly, however it will solve the global warming issue completely, which has been started since industrial revolution at 18^th century in UK.
