GE is supplying its Jenbacher biogas engine technology to power China’s largest ethanol production plant currently under construction in the city of NanYang, Henan Province.
Owned by Henan Tianguan Group, the new ethanol production plant will produce 500 000 m3 of biogas per day, based on organic material from cassava plants.
A 36 MW on-site power plant based on Jenbacher engines is 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 into ethanol.
For the 11 MW first phase of the new on-site power plant, GE is supplying four J620 biogas engine units. The gas engines will utilize the ethanol production facility’s waste methane biogas to generate renewable electricity, which Henan Tianguan Group plans to sell to the regional grid. The biogas engines also will use methane gas created by the anaerobic digestion of cassava biomass to produce renewable energy for use on site.
With an overall efficiency of 82.8 per cent (electrical efficiency 42.8 per cent and thermal efficiency 40 per cent), the new biogas power plant will provide Henan Tianguan Group with substantial operational and energy savings.
The project will also support China’s efforts to increase the use of biogas for renewable energy production and in motor vehicles.
In addition to the power sold to the grid, Henan Tianguan Group also will receive financing support through the sale of carbon credits, since the project has been registered with the Clean Development Mechanism.
