Biogas for cooking and electricity

Example of typical 8m3 domestic biodigester in Kenya

Biogas is a gaseous mixture generated during anearobic digestion processes using waste water, solid waste (e.g. at landfills), organic waste, and other sources of biomass. Biogas can be upgraded to a level compatible with natural gas (‘green gas’) by cleaning (removal of H2S, ammonia and some hydrocarbons from the biogas) and by increasing its methane share (by removing the CO2).

The following CDM methdologies are applied for biomass gasification projects: AMS-I.D.: Grid connected renewable electricity generation,  AMS-III.I.: Avoidance of methane production in wastewater treatment through replacement of anaerobic systems by aerobic systems, AMS-III.H.: Methane recovery in wastewater treatment, AMS-I.A.: Electricity generation by the user and AMS-I.C.: Thermal energy production with or without electricity for small-scale projects.

As of March 2011, there are 14 biomass gasification projects in the CDM pipeline, out of which 8 are registered and for 1 project CERs have been issued.

To provide small and mid-sized animal farms with an easy-to-use computer based tool, in  Portuguese, to calculate what it would take to install a biodigestor and generator, estimate potential MWh generation for consumption or sale to the grid, and to register and sell the methane emission reductions through the American Carbon Registry (ACR) or the CDM.

Main activity and output: 
  • Develop and make computer-based tool available on the web to quantify GHG reduction, estimate MWh  production and biofertilizer availability, calculate investment capital cost and expected revenues from energy sales
  • Pilot the tool on three animal farms/ operations and present the outcome to at least 100 animal farms in Brazil
  • Identify interested private sector, development bank and other funding sources and link to the trial projects
  • Undertake stakeholder outreach, communication and information dissemination
Expected impact: 
  • Increase in number of small and mid-sized animal farms installing biodigestors and generators, using the tool to obtain financing from banks
  • Increased methane capture and electricity generation, with increased farm income from sales back to grid
  • Additional farm revenue streams from CERs, thanks to ability to accurately quantify GHG reductions and their market value
  • Linkage between US and Brazilian financing institutions and local farmers
  • Reductions in methane and ammonia releases and significantly improved effluent discharge from intensive animal rearing
  • Enhanced capacity of local organisations like CENBIO to provide services after the end of the project
