Household Biogas projects are a well understood emissions reduction strategy that has been implemented for over a decade across multiple markets.
The process is scientifically well understood. Anaerobic biodigesters block out oxygen, resulting in decomposition of animal manure into methane-rich biogas that can be used for clean cooking and heat for the farm and household, and a nutrient rich slurry that can be used as an organic fertiliser.
The key challenge with these types of methodologies is managing performance and risk for highly decentralised operations over 10-15 year project periods.
What are the typical pain points?
The decentralised operations result in a very high cost of tracking and monitoring per tonne of carbon, relative to industrial-scale operations, and also for ensuring that units are being installed soundly and used correctly, with quick detection of equipment failure and/or fraud in installation.
