Producing natural gas from LPG Synthetic Natural Gas Generator "PA System"

For 35 years since its development, the “PA System,” which generates natural gas from LPG without the need for an external power sources such as electricity, has played an important role in post-disaster recovery. This system can be utilized in areas facing supply instability due to natural gas shortages, as well as as a countermeasure for emergency situations such as disasters. It is suitable for use by gas utilities, hospitals, welfare facilities, evacuation shelters, and various businesses, thereby strengthening energy security assurance.

The development of this technology began in 1990, prompted by an urgent request from a customer asking, ‘Could a device be developed that mixes LPG with air to supply city gas (natural gas) in the event of an earthquake?’
Just five years later, in January 1995, the Great Hanshin-Awaji Earthquake struck the city of Kobe in Japan.

Although the equipment was still in the development stage, it was deployed to assist in restoring the gas supply in the disaster-stricken area in response to the critical emergency caused by the severe disruption to the city gas (natural gas) supply. This marked the debut of this technology, and since then it has played a vital role in supporting people’s essential infrastructure at the scenes of numerous large-scale seismic disasters, including the Great East Japan Earthquake. 

Today, this technology is not limited to Japan, a country prone to earthquakes, but is also generating growing international interest as a solution to diverse energy security needs, such as:
・Backup gas lifelines in overseas regions prone to large-scale earthquakes
・Measures against geopolitical risks in countries heavily reliant on imported natural gas
・Resolving energy supply concerns in regions facing natural gas shortages
International expectations are rising for this technology as a solution to such diverse energy security needs.
