Amp Americas, part of the renewable transportation fuel industry, announced a milestone of 500,000 tons of CO2 greenhouse gas emissions eliminated, which is the equivalent of taking 100,000 cars off the road for one year. Additionally, Clay Walton has joined the company as vice president of RNG Services.

Walton will be responsible for leading and managing the company’s operations and maintenance capabilities and asset management services both internally and externally. As a member of Amp America’s senior leadership team, Walton will be tasked with overseeing new business evaluation, service execution strategies, continuous improvement, and asset management for Amp America’s operating assets and third party RNG assets. Walton will also further Amp’s unique expertise and leadership in biogas operations by promoting and developing RNG services to external clients’ operating plants.

Walton brings more than 30 years of industry experience leading operations, engineering, technology and asset management environments supporting $100+ million in renewable energy projects. Prior to joining Amp Americas, Walton was vice president of asset management at equity investment firm Ultra Capital where he led project O&M development and execution, and was responsible for long-term asset management of the company’s sustainable infrastructure investments. Walton holds a M.S. in environmental engineering from Colorado School of Mines and a B.S. in mechanical engineering from The University of Oklahoma.

“Clay’s wealth of leadership experience in creating operational value and his track record of performance will be extremely valuable as we continue to further scale our RNG Services project portfolio,” said Grant Zimmerman, CEO of Amp Americas. “We’re preparing to begin operations at our newest midwestern dairy biogas project at three farms. Clay will oversee our commissioning and operations for this project when it starts up this fall, as well as continue to oversee operations at our original Indiana asset portfolio.”

In July 2019, the company announced both a $75 million investment for new dairy RNG projects led by EIV Capital to support the continued growth and momentum that Amp Americas has built within the dairy RNG business, as well as an investment in its three flagship Indiana dairy RNG projects, including the largest on-farm biogas to fuel operations in the country.
