Infrastructure & publication requirements Networks Natural gas supply General information about natural gas as an energy source Natural gas is a primary energy. That means: The energy can be used directly without conversion. Underground lines bring it directly to the consumer. Compared to the other fossil fuels, natural gas is the most environmentally friendly and low - emission fuel. Burning natural gas produces 20 to 30 percent less carbon dioxide and virtually no fine dust. The advantages of natural gas at a glance: environmentally friendly funding without conversion stages can be used directly as primary energy environmentally friendly provision through underground transport domestic storage space is not required versatile economical in use clean and convenient Low in pollutants, residue-free, low-emission Where does our natural gas come from? Our natural gas network Natural gas in use Natural gas is a flammable natural gas that was created around two to three and a half billion years ago under elevated temperature and high pressure from dead and sunken animal and plant remains. Over the course of millions of years, these deposits were covered by layers of sand and rock. So-called digested sludge was initially formed under this top layer. Over time, a natural gas mother rock formed from this. Over very long periods of time and lengthy chemical processes, the gaseous hydrocarbons were pressed out of the natural gas mother rock and rose to the top of impermeable rock layers. Today's reservoirs, the storage rock layers, can reach depths of up to 7,000 m. The German gas industry obtains around 20% of its total natural gas requirements from its own domestic sources (mainly from Lower Saxony). There is an increasing tendency for deliveries from production areas such as the North Sea and Russia as well as from the production of renewable raw materials and the storage of excess wind energy.
