The use of grass biomass as a heating fuel has long held the promise of a fast growing, renewable, locally sustainable, and carbon neutral energy source. Unfortunately, grass biomass is a relatively new concept in the US and there are still many questions that need to be answered before grass can be fully utilized.

Growers need to know which varieties work best, what harvesting techniques should be employed and how grasses should be processed for use as a heating fuel. Residential and commercial-scale consumers need to know which available biomass boilers can burn grass and which grasses burn the cleanest. Biomass boiler manufacturers also need data on which grass varieties and processing methods work the best with their equipment and what changes may be required to successfully employ grass biomass as a heating fuel for their boilers.

Meach Cove Farms, a privately owned 1,000 acre certified organic farm engaged in research on renewable energy alternatives to fossil fuels, has recently published a project report on grass fueled heating equipment combustion optimization that presents answers to many of these questions. The research project, funded in part by a Vermont NRCS Conservation Innovation Grant, was a comprehensive study that included a review of grass biomass and currently available biomass boilers that could burn grass. In addition, they planted, harvested and processed a number of grass varieties into pellets and pucks and recorded combustion data for controlled test burns.

Evoworld is proud to have been selected as the biomass boiler of choice for Meach Cove Farm’s research project. Evoworld’s flexibility to burn fuels including wood pellets and wood chips and our advanced computer combustion controller were an excellent fit for Meach Cove Farm’s research needs.

Evoworld, a manufacturer of advanced biomass boilers located in Troy, NY, has been at the forefront of advancing research into biomass heating. We have worked with organizations such as NYSERDA, Brookhaven National Laboratory and Clarkson University to help promote biomass heating research and development.
