GE makes gas engines that feed on bio gas produced from a variety of foods and food by-products; and now these GE machines can also process synthetic gas, or syngas from wood. Many gas engines can run on natural gas, landfills gas, sewage gas, biogas, mine gas, coal gas, and syngas (such as the popular- Jenbacher).
In remote towns and villages, these gas engines supply power and they help cities integrate renewable energy into the power grid. The gas engines can also be configured with generators and other GE products to form power plants to supply power. This energy method is commonly used in areas such as Europe. GE has distributed power solutions including: generator sets, cogeneration systems and containers. Distributed Power is headquartered in Cincinnati, Ohio and you can learn more about it here: https://www.ge-distributedpower.com/
