Maas Energy Works

Maas Energy Works is a family-owned business based in Redding, California. Our founder Daryl Maas grew up in the dairy community and is passionate about using renewable technology to create value for farm families while improving the environment. We develop, own, and operate on-farm renewable energy facilities. We work with dairy families to create biogas out of cow manure and other organic wastes. We use that biogas to generate vehicle fuel, electricity, heat, and soon, hydrogen. Our 140 employees operate the nation’s largest fleet of dairy digesters on over 70 farms in 8 states.
