Using Biogas To Make Biogas
Supporting China’s efforts to increase the use of biogas for renewable energy production, GE is supplying its Jenbacher biogas engine technology to power an ethanol production plant under construction in the city of NanYang, Henan Province, China. Owned by Henan Tianguan Group, China, the new ethanol production plant will produce 500 000 m³ of biogas per day.
A 36 MW onsite power plant incorporating GE’s Jenbacher engines is also being built in multiple phases to support the ethanol plant’s operations. Both new facilities are being built adjacent to the company’s existing ethanol production facility, which uses a biomass digester system to convert cassava— instead of grain — into ethanol in China.
For the first phase (11 MW) of the onsite power plant, GE is supplying four of its J620 biogas engine units. The gas engines will use the facility’s waste methane biogas to generate renewable electricity, which Henan Tianguan Group plans to sell to the regional grid. GE’s biogas engines will also use methane gas created by the anaerobic digestion of cassava biomass to produce renewable electricity for the site, GE said.
When the 36 MW biogas power plant is fully operational, it is expected to reduce the equivalent of 1.1 million tons of carbon emissions a year, GE said. GE’s Jenbacher engines and associated equipment are scheduled for delivery to the project site starting in April. After completion of engine installation and commissioning, the biogas power plant, which has an 82.8% efficiency rating, is scheduled to begin operating in July, according to GE.
