Bioenergy project at NSW abattoir commences production

ReNu Energy has announced that the Goulburn Bioenergy Project, located at the Southern Meats abattoir in Goulburn has reached practical completion and commenced commercial operation.

The anaerobic digester and biogas treatment plant have been commissioned and are operational. The digester is receiving the full waste flow from the Facility and biogas production is ramping up with high gas quality. The two 800 kW dual fuel Caterpillar generators have been operated on both natural gas and biogas.

Chris Murray, Managing Director of ReNu Energy said, “The commercial operation of the Goulburn Bioenergy Project is a significant milestone for ReNu Energy and for the bioenergy sector in Australia. The project will supply approximately 4,000 MWh of energy annually, representing over 50% of the Facility’s power consumption and a significant reduction in energy costs and carbon emissions for our customer, Southern Meats.

The Project would not have been possible without the support of Southern Meats, and the

Australian Renewable Energy Agency (ARENA). We acknowledge and thank Southern Meats and ARENA for their support.”

The Goulburn Bioenergy Project is located at the Southern Meats Pty Ltd abattoir in Goulburn, NSW.

The Project includes an anaerobic digester, which is supplied with waste water from the Facility, biogas treatment plant, two 800 kW dual fuel Caterpillar generators and electrical interconnection to the Facility.

The electricity generated is supplied to the Facility at peak times of the daily billing cycle to reduce the Facility’s overall electricity costs. To be able to meet the peak demand periods, the generators can be operated on dual fuel, blending biogas with natural gas.

Dual fuel blending is a novel and innovative application in the field of bioenergy, enabling projects to better meet the demand cycles of customers and enhance project viability through the addition of natural gas.


Govt plans $2b boost to Snowy Hydro

The Government has revealed a $2b plan to boost energy generated by the Snowy Hydro Scheme by 50 per cent.

As the AFR reports, the proposed plan would involve a new series of tunnels and power stations to better utilise the existing Snowy Hydro infrastructure, rather than buid new dams.

Prime minister Malcolm Turnbull claimed that the new plan will add 2000mW of power to the scheme’s existing 4100mW output and will power 500,000 homes.

Four different design options using the Scheme’s existing dams will be looked at. The leading options are to rework the Tantangara Reservoir and the Talbingo Reservoir.

Turnbull said that his plan is better than South Australia’s than the giant battery storage facility that SA’s premier Jay Weatherill has unveiled.

“In one hour it could produce 20 times the 100MW per hour expected from the battery proposed by the South Australian government, but would deliver it constantly for almost a week, or 350,000 MWh over seven days,” Turnbull said.

However, the state is unlikely to back away from its plan. It wants to build South Australia’s generation capacity and contribution to the National Energy Market so it can export excess energy to Australia’s eastern seaboard.

Green energy plant praised for food processing potential

A green energy initiative by Japanese processor NH Foods at Oakey Beef Exports in Australia has been praised for its environmental and business efficiency model from food producers around the globe.

Opened by Australian Federal Industry and Science Minister Ian Macfarlane, the COHRAL plant extracts methane biogas from waste water streams to replace the costly natural gas that consumes millions of dollars in Queensland’s Darling Downs.

Biogas Technician at Oakey Beef Exports in Queensland, Katy Hawkins said “It is refreshing to see that such an established business has the foresight to decrease its’ environmental footprint. Globally, businesses are no longer in the position where infrastructure and productivity can be advanced without taking note of the damage it is causing the environment. It is especially exciting that this system is an Australian first.”

Producing approximately 183.3 gigajoules of energy a day when reaching design capacity through combusting methane, the plant delivers high quality waste water by extracting organic content that is later converted into methane to replace fossil fuels.

The plant is expected to deliver additional benefits which include reduced greenhouse gas emissions, improved quality of wastewater and greatly reduced odour emissions.

Hawkins said she was delighted to get the opportunity to be involved with the project, which involves an advanced user-friendly GWE SCADA-based control system operated by one person.

Global Water Engineering technology has been proven to work in a variety of livestock, crop and beverage production facilities and can be applicable to any industry with an organic waste stream.
