Transporting natural gas presents significant logistical challenges due to its physical properties, requiring advanced infrastructure to ensure efficient and safe delivery. Unlike crude oil, which can be transported relatively easily by tankers, natural gas must either be compressed into pipelines or cooled to extremely low temperatures to become liquefied natural gas (LNG) for shipment. These processes involve high costs and specialized equipment, making natural gas trade heavily reliant on infrastructure investments.

Russia holds a strategic advantage in natural gas exports to Europe due to its extensive pipeline network, which provides a direct and cost-effective supply route. Pipelines like Nord Stream and the Yamal-Europe network allow Russia to deliver large volumes of gas without the added expense and complexity of liquefaction and shipping. This proximity and infrastructure give Russia a dominant position in the European market, offering competitive pricing compared to LNG shipped from distant producers like the United States. In contrast, the U.S. exports natural gas primarily as LNG, which involves costly liquefaction facilities, shipping in specialized cryogenic tankers, and re-gasification at the destination. While U.S. LNG provides European nations with diversification and energy security, it typically comes at a higher cost than Russian pipeline gas.

Global production of dry natural gas was 145,000 Billion Cubic Feet (BCF) per annum. USA and Russia are the worlds largest producers of natural gas by a long shot, and make around 40% of world supply. Since the year 2000, roughly 21% of all dry natural gas came from USA, followed by Russia (19%), Iran (5%), Canada (5%), China (3%), Qatar (3%), Norway (3%), Saudi Arabia, and Algeria (3%).

According to the Energy Information Administration (EIA), global natural gas reserves stand at just over 6.922 million BCF, with the largest reserves being Russia (24%), Iran (17%), Qatar (13%), USA (5.3%), Saudi Arabia (4.2%), Turkmenistan (4%), United Arab Emirates (3%), Nigeria (2.6%) and China (2.4%). The remainder of the world makes up only around 24% of global dry natural gas reserves.

Based on the current annual production rate, and the estimated global reserves, there is c.47 years remaining of natural gas supply and could be reduced future given EIA growth forecasts, potential carbon tax, and natural gas’s preference over coal as a cleaner hydrocarbon for heating.

Natural gas, a fossil fuel, with a long history and a promising future, has played a crucial role in global energy mix and systems for centuries. Its transformation into liquefied natural gas (LNG) revolutionized its transport and use, making it a key player in the modern energy landscape.

The story of natural gas begins in ancient times, but its systematic use and exploration for energy purposes only took shape in the modern era. This period of discovery set the stage for the eventual realization of natural gas’s potential.
Natural gas has been known to humans for thousands of years. Ancient civilizations in Persia, China, and Greece encountered natural gas seeps, which sometimes ignited and created perpetual flames. These occurrences were often attributed to divine or supernatural forces.

The 19th century marked the beginning of natural gas’s use for industrial purposes. Technological advancements enabled its extraction, transport, and utilization on a larger scale. The first commercial natural gas well was drilled in 1821 in Fredonia, New York, by William Hart. Hart’s well was shallow, reaching only 27 feet, but it marked the beginning of natural gas extraction for commercial use. This gas was primarily used for lighting streets and buildings in the local area. By the 1880s, natural gas infrastructure began to expand in the United States. Pipelines were constructed to transport gas from production sites to urban areas, allowing for its use in lighting, heating, and cooking.
