Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-deprived environment. This biogas can be upgraded into biomethane through the removal of CO2 and other contaminants, constituting the predominant source, approximately 90%, of global biomethane production.
Biomethane is derived either from biogas upgrading or the gasification of solid biomass followed by methanation. This nearly pure methane source closely resembles standard natural gas, rendering it easily transportable and usable wherever natural gas is consumed. Its versatile applications span power generation, heating, and cooking, providing sustainable energy solutions, especially in areas with limited grid access or high heat demands beyond the capacity of renewable electricity alone.
Biomethane serves as a crucial low-emission alternative for reducing pollutants in challenging sectors like heavy industry and freight transport. Furthermore, it enhances the adaptability of existing gas infrastructure to a low-emission future, thereby improving the cost-effectiveness and security of global energy transitions.
Unlocking the Potential of Biomethane
Biomethane, according to the International Energy Agency’s Sustainable Development Scenario (SDS), is projected to prevent 1,000 million tonnes (Mt) of GHG emissions by 2040, encompassing both CO2 emissions from natural gas use and methane emissions from feedstock decomposition.
Biomethane and Biogas offer solutions to the dual challenges of increasing organic waste and reducing global greenhouse gas emissions. These gases represent a circular economy approach, leading to reduced emissions, improved waste management, and enhanced resource efficiency.
The untapped potential for biogas and biomethane is vast, estimated by IEA at 570 million tonnes of oil equivalent (Mtoe), and 730 million Mtoe, respectively. While the current production, around 35 Mtoe, is only a fraction of its full potential, which could cover approximately 20% of today’s global gas demand.
Furthermore, the availability of sustainable feedstocks for biomethane and biogas production is expected to increase by 40% by 2040, offering opportunities for every region. The overall potential is set to expand significantly in the coming decades, driven by a larger global economy and improved waste management practices in developing nations.
Our Biomethane Visions & Endeavours
Biomethane, along with carbon-neutral hydrogen, plays a crucial role in advancing energy transitions. While the share of electricity in global consumption is growing, it alone cannot drive these transitions amid increasing energy service demands. Biomethane is a significant contributor to low-carbon gas supply in the World Energy Outlook (WEO) Scenarios. The evolution of the biomethane and biogas industry varies by country, influenced by sectoral focus, feedstock availability, market conditions, and policy priorities.
We have been actively engaged in biogas upgrading for biomethane production since 2013, in collaboration with Green Methane, of which we are co-founders and exclusive partners in the biomethane industry. Our decision to explore this market long before the surge in carbon neutrality awareness demonstrates our profound understanding of the evolving landscape of energy sustainability. To date, we have successfully executed 4 biomass gasification projects and 15 projects related to biogas upgrading. Furthermore, we are currently involved in 10 additional biomethane production initiatives.
