From Poo to You with Safe Biomethane - webinar

Presented by Andrea Hosey (Advisian), Ruslan Davletgareev (Jemena), and Sheila Wujanto-Hawe (Jemena)

Biogas is a versatile renewable fuel that when upgraded to biomethane can be injected directly into the existing gas infrastructure.  This makes it attractive globally as a quicker waste to energy solution necessary to meet the energy transition net zero targets. Studies have indicated there is the potential to replace nearly 20% of New Zealand’s total gas usage with renewable gas by 2050.

Biogas is produced from a process known as anaerobic digestion where methane and other gases are produced by bacteria eating organic waste in an oxygen-free environment. Sources of organic matter range from animal manure, municipal waste, and food waste through to processed wastewater and sewage sludge.  The final composition varies depending on the organic matter, selected bacteria, and processing conditions but is largely methane, carbon dioxide and water vapour with relatively small amounts of other components.  However, small amounts of H2S can create significant safety hazards from both a toxicity and corrosion level.  The hazards are not so well understood outside of the hydrocarbon sector in traditionally “safe” industries such as wastewater treatment.

The focus of this webinar will be to: 

• Raise awareness of the safety issues associated with H2S – if you can no longer smell anything are you safe?
• Use the case study of the Jemena’s Malabar Biomethane Injection plant to demonstrate what good practice is in relation to the introduction of managing gas containing H2S.

The Malabar Biomethane Injection plant is a joint initiative between Sydney Water and Jemena supported by ARENA funding.  It is the first of its kind in Australia.
