First on our list is Plug Power, a ‘green power’ player designing and manufacturing zero-emission hydrogen fuel cell systems, including the production, storage, and delivery infrastructure needed to build out this new technology to industrial or utility scales. Hydrogen fuel cells use electrochemical reactions to generate usable electric power. The result is a cleaner power source, based on clean, renewable hydrogen – the most common element in the universe.Plug Power’s hydrogen fuel cell battery products have found uses in both motive and stationary applications, including backup power generation and in warehousing. The fuel cells are growing in popularity with data centers, and have been found to be cost-effective in warehousing, where they are used to power pallet jacks and fork lifts.
