Plug Power names Dr. Lee Sweetland as engineering industrialization lead

Plug Power Inc. (NASDAQ: PLUG) has appointed Dr. Lee Sweetland as Global Engineering Industrialization Lead, the company announced Oct. 19, 2026.

Sweetland will oversee the industrialization of Plug Power's proton exchange membrane (PEM) stack technology, with a focus on manufacturing performance, product reliability, and cost competitiveness. He will also concentrate efforts on the company's Rochester, New York Gigafactory, which produces PEM stacks.

Sweetland previously spent eight years at Ballard Power Systems, where he most recently served as Chief Operating Officer, after holding roles as Chief Transformation Officer and Vice President and Director of Advanced Manufacturing. Before that, he held senior manufacturing and operations positions at Johnson Matthey's fuel cell business.

"Electrolyzers are a major driver of Plug's growth, and our ability to execute at scale is just as important as winning new business," said Jose Luis Crespo, Chief Executive Officer of Plug Power. "Lee brings deep experience in industrializing fuel cell technology and improving manufacturing performance."

Plug Power cited several active electrolyzer projects across global markets. In Europe, these include Iberdrola's 25 MW facility in Spain, Galp's 100 MW project in Portugal, Carlton Power's 30 MW project in the UK, and a 280 MW Arcadia eFuels project in Denmark. In North America, the company is involved in Hy2gen's 275 MW project in Québec. In the Asia-Pacific region, projects include Orica's 50 MW project in Australia and a 1 MW project for HWR Hydrogen in New Zealand.
