ENERGY Networks Australia and Bioenergy Australia recently hosted a Renewable Gas Sym- posium in Sydney.
This symposium ex- plored emerging innova- tions and research in hy- drogen and biogas.
The drivers pushing businesses to consider utilising low carbon gas and the injection and pol- icy mechanisms needed to support it being blended into existing gas networks.
It was evident that major gas corporations across Australia are committing to the development of hy- drogen energy projects and there are currently 10 projects being piloted in development across the country.
Hydrogen can play an important role in helping Australia’s gas networks decarbonise and store en- ergy.
Biogas is also considered to be very important to the development of hydro- gen technology as it is one of the cheapest forms of energy, particularly when waste products are used to produce it.
Hydrogen is expensive to produce and transport but can be utilised in electric vehicles (think hydrogen fuel cells), with the by- product (exhaust) being water.
In 15-20 years, the thought is there will be a blend of biogas and hy- drogen in gas networks to reduce CO2.
Energy Networks Aus- tralia has produced Fig- ure 1 on renewable gas sources.
So, what does this mean for pork producers?
Currently, about 15 per- cent of the industry pro- duces biogas from covered anaerobic ponds for its own heating, cooling or electricity needs.
Some producers also feed the surplus energy into the electricity grid.
The information pre- sented at the conference clearly shows biogas is an important contribution to the renewable gas sector.
The Symposium includ- ed a presentation from the Ministry of Foreign Affairs from Denmark, which discussed the steps taken to develop their bio-
energy include:
1. Two-thirds of energy
is lost in conversion;
2. It is costly to produce;
emissions each year.
• Value drivers include:
- Continuous and dis- patchable energy source;
- Renewable energy;
- Produces energy from waste; and
- Supports local econo- mies and regional com- munities.
• As a renewable natural gas, biomethane can re- place natural gas by being injected into the existing gas grid. Therefore, it can provide a cleaner energy to large industries, busi- ness and households as well as fuel for vehicles.
Water treatment facili- ties, such as Sydney Water, are also beginning to use

gas industry.
This included a commit-
ment to reducing methane output from agriculture where it has been man- dated that 50 percent of manure by-product must
be utilised in biogas pro- duction by 2020 and this includes a 20 percent in- vestment grant to develop the technology.
Key challenges to the development of hydrogen
In addition to the devel- opment of hydrogen en- ergy, the Australian biogas industry has significant untapped potential.
• The investment oppor- tunity for new bioenergy including biogas projects is estimated at $3.5-5 bil- lion. Biogas also has the potential to avoid up to 9 million tonnes of CO2-e
