WELtec Enters China Market

Posted on January 12, 2010

WELtec BioPower GmbH, Germany has received an order for a biogas plant setup in Wuxi, China a city of 4.5 million located west of Shanghai. Construction work on the 370 kW plant is expected to begin in the first quarter of 2010. According to the company, WELtec was chose due to the fact that they manufacturer all of their own parts.

The plant's two 1800 cubic meter fermenters will be fed with 15 000 tons of pig manure and 1500 tons of rice straw a year. The resources will come from farms in the vicinity. The biomethane produced will be used for the city's own use as it is not common practice as this time to feed generated energy into the electricity grid, said the company.

Although coal is a primary energy source in China, outages are often experienced due to low efficiency of the coal-fired power plants. This is driving a trend toward decentralized combined heat and power supply with biogas becoming increasingly popular, especially in the rural areas. Biogas potential is estimated at 5 tcf per year.

Today, more than 800 MW is generated in the sugar provinces of Guangdong and Guangxi alone. The goal, by 2020, is to equip 7% of the rural households with biogas plants, increasing the share of renewable energies in power generation to 15% by 2020.
