BIO-CNG POWER VEHICLES IN CHINESE CITY OF YANTAI
Environmental awareness is growing in China, and with it the market for compressed natural gas (CNG). Germany company EnviTec Biogas AG, a manufacturer of biogas production equipment, says that one of the several CNG filling stations in the eastern Chinese port city of Yantai is now taking deliveries of biomethane from two 1,000 Nm³/h EnviThan gas upgrading plants.
A recently installed CNG plant compresses the biomethane from around 13.5 bar to 200 bar in CNG tube trailers. The first trailer for delivery to Yantai, a trip of around 90 minutes by road, was filled recently at this plant. Equipped with Sepuran® Green membranes, the EnviThan gas upgrading plant run by Shandong Minhe Biological Sci-tech is also the largest plant featuring this membrane technology in the Chinese market. Based in Penglai, Shandong province, the company is one of the world’s largest poultry producers – its biogas plants are run exclusively on poultry litter.
While Germany acknowledges the advantages of bio CNG (renewable natural gas – RNG) as a carbon-neutral fuel, progress in developing the necessary infrastructure has been sluggish to date. dena (the German Energy Agency) notes that the lack of an ambitious, technology-neutral policy for promoting alternative fuels and drive systems means that a 4% market share, identified the benchmark for a self-sustaining alt-fuel market, is still unlikely to be met before 2026.
