Sean Casten founded and led two clean energy companies, Turbosteam Corporation and Recycled Energy Develompent from 2000 to 2016 that shared a common mission to profitably reduce greenhouse gas emissions. Recycled Energy Development LLC (RED) developed, owned and operated of energy assets inside in industrial facilities that recovered otherwise-wasted energy and converted into heat and power in fulfillment of its mission to profitably reduce greenhouse gas emissions. Turbosteam Corporation was a designer and packager of custom-engineered steam turbine power plants that recovered the energy in existing pressure differentials in steam distribution systems to generate fuel-free (or nearly free) electricity. Before getting the entrepreneurial bug, Sean worked in Arthur D. Little's energy practice, where he specialized in emerging fuel and power generation technologies, and was a researcher at the Tufts School of Medicine, working in a lab that did basic research related to breast and colon cancer.
In 2005, he was recognized by the US Combined Heat and Power Association as a "CHP Champion" in recognition of leadership towards greater national use of clean, efficient, and reliable combined heat and power. In 2009, he was recognized as an Emerging Leader by the Chicago Council for Global Affairs.
He was the 2007 Chairman of the United States Combined Heat and Power Association and the founding (2005) Chairman of the Northeast Combined Heat and Power Initiative. He is a contributing blogger at the environmental site Grist.org.
Sean holds a BA from Middlebury College and an MS and MEM from Thayer School.
