Rapid growth in the population, and increasing urbanization and modernization across the globe is increasing the demand for energy. Currently, major energy demand is supplied by fossil fuels such as coal, and oil & gas. Fast depleting fossil fuels, environmental concerns and rising pollution has led to steady shift to more environment friendly and renewable fuel sources of clean energy. Biogas is a clean, renewable and biological source of energy. It is produced when organic material such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste are decomposed under anaerobic conditions. It is also produced under controlled conditions in a digester chamber.
Biogas primarily consists of methane, carbon dioxide, hydrogen sulphide, moisture and siloxanes. It is purified, processed and liquefied to be used as a fuel. This process is called as liquefaction of biogas. In a biogas liquefaction plant, purified and upgraded biogas is converted to liquefied biogas under specific pressure and temperature. Purest kind of liquid biogas consists of approximately 97% methane. Liquefied biogas is approximately 600 times more space competent than in gaseous state; it is much easier to transport liquefied biogas. Liquefied biogas is produced in two main ways such as cryogenic technology and conventional upgrading technology. Certain procedures such as biogas production, pre-treatment, liquefaction, storage and transport are carried out in a biogas liquefaction plant.
The biogas liquefaction industry is expected to register significant growth in the near future. Countries such as Sweden and Netherlands have started the use of liquefied biogas for running vehicles. Certain trains and trucks also use liquefied biogas as fuel. Public transport buses in Sweden and other regions now use liquefied biogas as fuel. Cargo ships have also started use of liquefied biogas in certain regions. Production of biogas also leads to proper waste management. Liquefied biogas burns more cleanly and emits less carbon dioxide, which helps in controlling the global warming and environmental pollution. As petrol and diesel are polluting and impermanent fuels, many vehicles have switched to liquefied biogas. To support this rising demand for liquefied biogas, many biogas liquefaction plants and units have been installed worldwide.
The global biogas liquefaction market can be segmented based on the technology and geography. The two main technologies for biogas liquefaction are cryogenic technology and conventional upgrading technology connected with a small-scale liquefaction plant. Europe and North America are comparatively mature markets for the biogas liquefaction. The U.S.A, Sweden, Switzerland, Germany are the major drivers in these regions. Asia Pacific and the Middle East are in the nascent stage but are projected to register higher growth rate in the near future. In recent years, China has made huge investments in biogas plants and other alternate sources of energy. Australia has built many big and small sized biogas liquefaction plants in recent years. Rapid shift to liquefied biogas as primary source for fuel in vehicles would spur the growth of biogas liquefaction plants.
Efforts from South Korea, Indonesia, Malaysia, India and South Africa to promote the use of biogas is expected to enhance growth in these markets. High biogas demand could directly or indirectly fuel the demand for biogas liquefaction plants across the globe. As per the recent regulations in Sweden, the country imports waste to produce biogas, which may fuel additional growth in the biogas liquefaction market. As many as 11 new biogas liquefaction plants have been built in Sweden.
France, Sweden and U.K have committed to produce liquefied biogas with a goal to meet 20% of their energy demand through biogas. Comprehensive shift to renewable energy from fossil fuels may increase biogas demand. But improper waste management could confine the market growth. However, recent global shift to renewable and clean energy along with technological developments in biogas processing and applications around the globe point towards a positive outlook for the biogas liquefaction industry.
