(138b) Green Hydrogen from Green LNG

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. One idea to reduce the CO2 emission for energy production, hydrogen from green LNG is considered. Hydrogen is a representative fuel for fuel cell of FCV and various electrical power generation for industrial and municipal use, which will not cause the CO2 emission.

• 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 liquefied as green LNG and transferred to consumer site by LNG tanker.
• Receiving Terminal and Hydrogen Generation: application of autothermal reactor to produce hydrogen, CO2 recovery by amine process from autothermal reactor.
• The CO2 is compressed by compressor, liquefied and transferred by LCO2 tanker and recycled to the SNG synthesis.

This concept would lead to higher energy costs for the consumer compared to fossil fuel, however it will solve the global warming issue, which has been started since industrial revolution at 18^th century in UK.
