Is there a Primer on Need and processes for upgadation of Biogas?

[Natalia Bourenane]

I am not sure I understand your question. Can you please rephrase or maybe provide some additional details?

[Saeid Tajbakhsh]

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.

Selection of best upgrading technology can be a key for project success. Several considerations should be carefully assessed such as 1) type of feedstock which determines what do expect in the biogas. 2) Size of the project (flowrate of biogas). Some technology could be the best for a certain type of feedstock but may not be commercially available for the project size, range etc. 3) Compliance and Construction issues are also important factors. Some of the technology providers from other parts of the world may not be fully ready for the compliance requirements in the project’s jurisdiction which may delay the project. Also, less work to be done on-site is better. Commercially available plug and play upgrading systems are great to reduce construction hassles and time etc. 4) Degree of automation and cyber security: Often times, this could be underestimated while making the decisions but paly crucial role 5) Last be not the least, please discuss with the Operations team to go through a thorough review as they are the ones will have to deal with the system every day.

The best upgrading technology for a biogas project depends on many different parameters:

• CapEx availability
• OpEx sensitivity
• Scalability of output
• Complexity to operate the upgrading system vs available personnel
• Site location – i.e. family farm vs industrial location

The best way to decide is to contact suppliers from different technologies and discuss the needs of your project. Understand that you would have to operate the upgrading system long term, so any choice you make needs to take into consideration costs, time, technical skills needed etc.

I am happy to chat with anyone who is debating between different upgrading technologies and give my professional opinion.
