Renewable natural gas supply contracts. Applications: In contrast to being renewable, biogas creates similar environmental pollutants as ordinary natural gas fuel, such as carbon monoxide, sulfur dioxide, nitrogen oxide, hydrogen sulfide and particulates. Any unburned gas that escapes contains methane, a long lived greenhouse gas. The key difference from ordinary natural gas is that it is often considered partly or fully carbon neutral, the carbon dioxide contained in the biomass is naturally renewed in each generation of plants, rather than being released from fossil stores and increasing atmospheric carbon dioxide. Renewable natural gas Renewable Natural Gas (RNG), also known as Sustainable Natural Gas
Natural gas storage reservoirs; up to 80% of the total gas volume. Most aquifer storage facilities were developed when the price of natural gas was low, meaning this cushion gas was inexpensive to sacrifice. With rising gas prices aquifer storage becomes more expensive to develop. A consequence of the above factors is that developing an aquifer storage facility is usually time consuming and expensive. Aquifers are generally the least desirable and most expensive type of natural gas storage facility. Underground salt formations are well suited to natural gas storage. Salt caverns allow very little of the injected natural gas to escape from storage
