The world energy industry has reached a fundamentally new level of socio-economic development recently, when the key question has switched from “What do we use for fuel?” to “How do we fuel?”. The industry offers many different energy options from coal to tidal energy. At the same time, humanity makes its choice, turning away from the cheapest and most affordable sources that used to be the trend thirty years ago, to the most environmentally friendly and energy-efficient energy sources. The key global players such as the European Union, Japan, USA, China and Russia are now busy establishing conditions for investment in the development of new energy technologies. One of the most promising options may be the widespread use of hydrogen as fuel and energy storage.
