Walmart boosted its commitment to hydrogen energy in its distribution network by agreeing to back a fuel-cell company and acquire more of its products.

The big-box chain plans to adopt Plug Power's fuel cells and hydrogen stations to bolster its energy efficiency at up to 30 more locations. The retailer had already installed Plug Power fuel cells at 22 distribution centers.

The deal jolted Plug Power stock, which rose 10.7% to $2.35 at 10:20 a.m. Friday.

Walmart also received warrants to acquire up to about 55.3 million shares of Plug Power stock, including 5.8 million warrants that were exercised as a result of the latest fuel cell purchasing deal.

The fuel cells help replace lead-acid batteries and power devices such as forklifts to improve warehouse efficiency.

“Our expanding relationship with Walmart validates Plug Power’s advanced capabilities in fuel cell products and systems, allowing the world’s largest retailer to maintain its leading position as an industry innovator,” Plug Power CEO Andy Marsh said in a statement.
