Hokkaido town converts cow manure into hydrogen fuel

interestingengineering.com

A town in Hokkaido, Japan, has developed a method to convert cow manure into hydrogen fuel. This innovative approach utilizes the region's abundant dairy waste, aiming to produce 18,500 gallons of clean fuel for vehicles, especially agricultural ones. The Shikaoi Hydrogen Farm, opened in 2015, uses anaerobic digestion to break down cow waste, generating biogas that is refined into hydrogen. This facility can fill about 28 hydrogen-powered vehicles daily and also supplies excess fuel to local businesses. Japan is exploring similar projects, including one in Fukuoka that converts human sewage into hydrogen for municipal vehicles. These initiatives highlight a growing trend of transforming waste into renewable energy, despite challenges in production costs and storage.
