Now the Group’s second largest market, the Global biogas upgrading market is growing rapidly. According to a recent report it is anticipated to reach $1.97 billion by 2022, which represents a compound annual growth rate (CAGR) of 28.7%. Government regulations, greenhouse gas emission targets, an increased need to treat residues and wastes coupled with a growing demand for renewable energy are driving growth in this market. These drivers exist as part of the world’s commitment to reduce its greenhouse gas emissions, concern over air and water pollution, security of energy supply and reducing reliance on fossil fuels while continuing to meet rising energy demands.
Biogas is produced naturally when organic matter such as food waste from households, manure, or crops from agriculture is broken down by micro-organisms in anaerobic digesters (AD), landfill and wastewater treatment plants. It is a mixture of around 60% methane and 40% carbon dioxide. Upgraded biogas, known as either biomethane or Renewable Natural Gas (RNG) can then be used as a vehicle fuel or injected directly into the gas grid network. It uses existing waste and infrastructure to create a renewable energy within a relatively short time frame and in addition creates a profit for the gas producers.
There are four main biogas upgrading technologies, water-wash, pressure swing adsorption (PSA), chemical scrubbing and membrane separation. Water-wash is the most widely used technology, accounting for around 40% of the market, closely followed by PSA at 25%, with membrane separation taking a growing market share. Greenlane is a market leader in water-wash and the only company to also supply PSA and membrane, making it technology agnostic.
The opportunities for biogas upgrading are world-wide. Europe is the most mature market for biomethane and further significant growth opportunities exist here driven by Government targets and support. In France for example, the vision of the French Environment and Energy Management Agency is to produce 70 TWh biogas annually by 2030, with 50% of the biogas produced, injected into the grid. North America is expected to see a major expansion in biogas upgrading where the scope for upgrading is substantial. Greenlane is a market leader in Europe and North America.
