A few years ago, reducing domestic gas production in the U.S. and Europe amid growing demand for consumer markets, meant that the supply of LNG, often from remote sources started to gain more widespread. Dependence on a few countries - including Russia, Qatar, Iran, Turkmenistan and Australia, who control much of the conventional natural gas deposits, it seemed could worsen further. The development of unconventional gas in the U.S. since 2006 has caused a revolution not only on the U.S. energy market, but also became the starting point for fundamental changes in global gas markets . Dr. Frank Umbah, Deputy Director of the European Centre for Energy and Resource Security (EUCERS) at London Royal College, has kindly agreed to share with Ukrainian readers his views on the current state and strategic perspectives of unconventional gas in Europe, which formed the basis for the next release MethaneSphere 2 (11).
