Biomethane offers more flexibility and higher value, especially for use in transportation and injection into the natural gas grid. While CHP still makes sense in places with steady heat demand or no access to the gas network, the market is moving toward upgrading technologies that use less energy and support broader decarbonization and energy goals. In Canada and across North America, policies like the Clean Fuel Regulations and Low Carbon Fuel Standards are helping drive this shift by providing stronger incentives for renewable gas, making biomethane a more practical and valuable option.
Thank you for the question. Our biogas upgrading platform is designed to be both cost-effective and operationally flexible. Compared to available biogas upgrading systems, our approach offers up to 50% lower capital and operating costs. These cost advantages are due to the system operating under mild conditions, which significantly simplifies the biogas upgrading platform and reduces operating requirements, resulting in lower CAPEX and OPEX.
I completely agree that RNG is becoming a more compelling and accessible option for remote and rural areas.
We have seen this need in our work, particularly in settings where traditional infrastructure is limited or unavailable. To address this, we’ve developed mobile upgrading systems that can be transported directly to sites like farms, landfills, and wastewater treatment facilities. These units allow operations to become more energy autonomous, reduce emissions, and turn local waste streams into valuable energy—all without requiring permanent infrastructure.
From our experience, solutions like this are making RNG a viable and scalable path forward, even in the most challenging locations.
The best biogas upgrading technology depends on several key factors, including the composition of the feedstock (such as levels of CO₂, H₂S, air, and moisture in the biogas), project location (availability of utilities, space constraints, and climate), and the required gas quality based on regulatory or market standards. Technologies must be matched to the specific context. Some perform better with certain feedstocks or in areas with limited utilities. Low-footprint systems with low operating costs and flexible purity control are often preferred, especially for distributed or resource-constrained sites. Depending on the level of contaminants in the biogas, additional treatment steps may be required to remove compounds like H₂S, nitrogen, or oxygen. Modern upgrading systems now offer integrated solutions that combine multiple treatment steps into a single package, significantly reducing both capital and operating costs.
