What They Do
Maas Energy Works specializes in the production of biogas through anaerobic manure digesters, primarily converting dairy and some swine waste into renewable natural gas (RNG), electricity, heat, and emerging hydrogen. The company employs innovative lagoon cover systems that capture methane at a lower cost compared to traditional tank digesters, making it a leader in the renewable energy sector (source: maasenergy.com). Their full-service offerings encompass design, procurement, financial projections, grant financing, permitting, construction management, operations, maintenance, and in-house fabrication, which includes divisions like Maas Motor Works and Goose Works (source: maasenergy.com). Targeting US dairy farms and commercial facilities, Maas Energy Works serves 16 of California's 28 operating dairy digesters, providing clients with revenue opportunities from RNG and electricity sales while managing ownership and operational risks (source: thevine.ucanrinnovate.io). Their commitment to serviceability and innovation, such as assembling turbocharged gensets and virtual biogas pipelines, sets them apart in a competitive market (source: maasenergy.com).
Projects & Track Record
Maas Energy Works has an impressive track record, having completed over 70 new or upgraded dairy digester facilities across 11 states, all of which remain operational. Notable projects include the first California digester at Van Warmerdam Dairy, operational since May 2013, and the Pixley Biogas project with Calgren Renewable Fuels, which offsets up to 4% of the natural gas used by an ethanol plant (source: maasenergy.com). The company has also developed the Stillwater Ranch project in Hanford, CA, which utilizes a virtual pipeline to deliver biogas as compressed natural gas (CNG) for vehicle fuel, and upgraded the Hilarides Dairy digester to enhance efficiency and reduce emissions (source: maasenergy.com). With a focus on operational uptime, Maas Energy Works boasts a 100% uptime record across its 70+ projects, showcasing their reliability and commitment to quality in the renewable energy sector (source: maasenergy.com).
Recent Developments
In recent years, Maas Energy Works has announced a significant joint development agreement with Clean Energy Fuels Corp. to construct nine RNG facilities at dairies across seven states, with a projected investment of approximately $130 million (source: cbinsights.com). This initiative underscores Maas's position as the largest dairy digester developer in the nation, with over 60 projects completed to date (source: americanbiogascouncil.org). Additionally, the company has launched its Goose Works division for in-house biogas cleanup, further enhancing its operational capabilities (source: maasenergy.com). While there have been no reported acquisitions or new funding rounds beyond the previous total of $1.56 million, Maas continues to innovate and expand its project pipeline (source: maasenergy.com).
