Sydney Water – 5 x sewage gas cogeneration sites - Case Study
Clarke Energy have been contracted by Worley Parsons on behalf of Sydney Water to design, supply and commission the GE Jenbacher cogeneration engine package, with exhaust gas heat recovery. The engines use the sewage gas produced by the on-site digesters to produce renewable power. In turn the heat generated by the engines through the combustion will go back to the digesters, increasing gas ...

Precise biogas flow measurement: Overcoming the challenges of changing gas composition
INTRODUCTION As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is ...

What is "Net-Zero Cooling To Power"
Rankine Cycle and Organic Rankine Cycle Waste heat is a vast, underutilized, and sustainable source of energy that is often overlooked due to the costs involved with capturing and converting that heat into electricity. Rankine cycle (RC) systems have been used for decades to generate clean electricity from heat, however these systems are restricted to sources of high-temperature heat such as ...
