Electric Power Research Institute
The Electric Power Research Institute (EPRI) conducts research, development and distribution relating to the generation, delivery and use of electricity, and is committed to supporting and developing innovative solutions to the challenges that face electricity producers and consumers. One such challenge is what to do with the millions of tons of synthetic gypsum (calcium sulfate) that power plants produce each year. Gypsum is produced when certain types power plant “scrubbers” remove sulfur (mandated by the Clean Air Act to prevent acid rain) from their exhaust plumes. The product is a very pure and high quality material with a number of beneficial uses. However, a significant percentage of the synthetic gypsum generated every year must still be landfilled, at a cost to both the producers and the environment.
Greenleaf Advisors is helping EPRI develop and coordinate primary research with partners like The Ohio State University to find and deploy environmentally beneficial uses of synthetic gypsum. Our research underway in Ohio is studying gypsum’s effect on phosphorus in farm fields. Excess phosphorus from fertilizers and manure often makes its way into our rivers and lakes, where it triggers blooms of toxic algae that harm regional economies, human health, and the environment. This study is demonstrating on actual working farms that a single, cost-effective application of gypsum can quickly and dramatically reduce the phosphorous that leaves the field in water runoff.
Greenleaf has been assisting EPRI with the coordination and management of the research team, identification of appropriate field sites, and outreach and education initiatives to ensure that the people and policy-makers who need to know about and benefit from these techniques, are able to. Our experience working with a wide range of stakeholders made us the right choice to not only help put together the research team, but to reach out to industry, academia, and government agencies with the valuable lessons we have learned.
The Greenleaf team brings together people to deliver sustainable solutions for the productive use of land, water, material and energy resources that sustain us all.
This Monday, John Andersen and Katie DeMuro traveled to Bryan, Ohio to visit the Ohio gypsum project team including NesterAg, The Ohio State University, GYPSOIL and the USDA ARS.
Turn on an electronic switch, and a myriad of services flows our way – increasingly from sustainable energy sources that are being delivered to us in intelligent fashion – just ask our colleagues at Intelligent Generation or GreenCity Power who deliver clean affordable power to customers as profiled below.
The webinar, “Building Profitability and Protecting Water Quality through Gypsum”, was hosted by the Partnership for Ag Resource Management on December 15, 2015. Dr. Warren Dick, professor of soil and environmental science at The Ohio State University, presented on the current state of the science on the effectiveness and applicability of gypsum as a soil amendment. Cory Schurman, National Sales Manager from Gypsoil, discussed the value gypsum offers to growers through improved productivity and sustainability.
It takes a long time for an ecosystem to develop, as well as to decline. They lose vitality gradually, until after years of abuse the damage becomes impossible to ignore. Sustainable solutions can take a long time to develop as well.
