- The continuous rise in energy consumption presents a serious problem in the current context, as almost 80% of global energy production is still derived from fossil fuels.
- In Portugal, the goal is 32% renewable energy sources for final consumed energy by 2030 as well as a 40% reduction of greenhouse gas (GHG) emissions about the levels recorded in 1990.
- Portugal has the potential to produce 378 million years of biomethane and Europe could potentially produce 25727 million years of biomethane.
- The new Finnish biogas statistics were published on September 30 and contain very encouraging figures on biogas consumption in transport. The consumption nearly tripled, with an increase of 168% while the upgrading capacities tripled and many new filling stations were open. Much more is expected in the next 3 years.
- At the same time, a decrease of 2% in heat and power consumption was recorded. The new publication covers the entire period of traffic biogas utilization from 1941 until August 2014. Within the last two decades biogas production has increased 6-fold and within the last decade biogas consumption in transport has increased 5400-fold.
- Biogas typically contains 60% methane and 40% carbon dioxide. It is produced through anaerobic digestion of easily degraded biomass
- Before injection into a natural gas grid and/or use in vehicles, biogas needs to be upgraded to approximately 97% methane and purified from contaminants such as siloxanes and sulfur.

- This implies the storage of the gases within the form entry and the fermentation residue storage under membrane roofs. Only about 7 % of the plants have external gas storage.
- The results of the survey of operators in 2016 (the reference year 2015) show that around 30 % of the gas storage roofs are installed with single-layer membranes. An additional 63 % of the installed gas storage roofs are double-layer membranes.
- 2200 to 2800 biogas plants were operated with less than 30 % excrements respectively more than 70 % energy crops (mass based). Biogas plants, which are predominantly based on energy crops, are mainly designed in larger capacity ranges. In total 1000 – 1100 biogas plants were based on 100 % energy crops with an average plant capacity of 580 kWel.
- Plant operators used less than 25 % of generated heat for external heating purposes, whereas about 44 % of biogas plants showed less than 50 % of external heat utilization.
- Total Capacity: As of the latest reports, the global biogas capacity has reached over 15,000 biogas plants, with Europe leading with more than 10,000 plants, followed by the United States with around 2,200 plants.
Emerging Trends
- Increased Adoption of Upgrading Technologies: One of the significant trends is the advancement and adoption of biomethane upgrading technologies. New technologies are enhancing the efficiency of purifying biogas to meet the standards required for natural gas grid injection. Innovations such as pressure swing adsorption (PSA) and membrane separation are becoming more prevalent, allowing for higher purity and greater integration into existing energy infrastructures.
- Growth in Waste-to-Energy Projects: There is a notable increase in the number of waste-to-energy projects focusing on biomethane production. Municipalities and industries are increasingly investing in systems that convert organic waste into biomethane, addressing both waste management issues and energy needs. This trend is driven by rising landfill diversion regulations and the economic benefits of utilizing waste as a resource.
- Expansion in Transportation Fuel Use: Biomethane is gaining traction as a viable alternative fuel for transportation. Companies are investing in infrastructure to support the use of biomethane as a clean fuel for buses, trucks, and other vehicles. This shift is part of a broader push to reduce emissions from the transportation sector and enhance the sustainability of logistics and public transit.
- Policy Support and Incentives: Governments and regulatory bodies worldwide are increasingly supporting biomethane production through incentives, subsidies, and favorable policies. For example, the European Union’s Renewable Energy Directive and various national policies are providing financial support and setting targets for renewable gas usage, boosting market growth.
- Technological Integration with Digital Tools: The integration of digital tools and data analytics into biomethane production processes is another emerging trend. Advanced monitoring systems and predictive maintenance technologies are being used to optimize operations, reduce downtime, and improve overall efficiency. This trend reflects the broader movement towards digitalization in the energy sector.

This trend is supported by growing consumer and corporate demand for environmentally responsible practices.
Use Cases
- Waste-to-Energy Conversion: Biomethane is increasingly utilized in waste-to-energy projects, where organic waste such as food scraps and agricultural residues is converted into renewable energy. For instance, in 2022, over 200 waste-to-energy plants globally used anaerobic digestion to produce biomethane, processing around 12 million tons of organic waste annually. This application not only reduces landfill waste but also provides a sustainable energy source.
- Renewable Natural Gas (RNG) for Transportation: Biomethane is becoming a popular alternative fuel for transportation, especially in public transit and logistics. In 2023, the use of biomethane as a vehicle fuel increased by 25% in Europe, with over 1,500 public transport buses running on RNG. This shift helps reduce greenhouse gas emissions from vehicles, offering a cleaner alternative to diesel and gasoline.
- Industrial and Residential Heating: Biomethane is also used for heating applications in both industrial and residential settings. In Germany, for example, biomethane accounted for about 3% of the country’s residential heating energy in 2023, contributing to reducing reliance on fossil fuels. This use case underscores biomethane’s role in diversifying energy sources and enhancing energy security.
- Power Generation: Biomethane is used to generate electricity in combined heat and power (CHP) plants. In the UK, biomethane-powered CHP systems produced approximately 1.2 terawatt-hours (TWh) of electricity in 2022, which is equivalent to the energy needed to power around 350,000 homes. This application supports grid stability and provides a renewable energy source.
- Grid Injection: Another growing use case is injecting biomethane into natural gas grids. This practice is expanding in regions like Europe, where countries such as Sweden and the Netherlands have integrated biomethane into their gas networks. In 2023, approximately 1.5 billion cubic meters of biomethane were injected into European gas grids, contributing to the reduction of carbon emissions from conventional natural gas.
- Agricultural Operations: Biomethane production is being integrated into agricultural operations to manage livestock waste and generate renewable energy. For instance, large dairy farms in the United States are using anaerobic digesters to process manure, producing biomethane that supplies power to farm operations and local grids. This use case helps manage waste effectively while providing energy for agricultural needs.
