In a Thursday interview with CNBC's Jim Cramer, Cummins CEO Jennifer Rumsey explained why hydrogen plays a role in the company's strategy.
"We need hydrogen, hydrogen has to be a part of the answer," she said.
"And the reason is, you've got renewable energy that we need to convert into some kind of fuel, transport, and have it available when we need it."
Rumsey explained that hydrogen can provide a way to store renewable energy and transport it to where fuel is needed.
"We're investing today in hydrogen engines, so we'll be able to burn hydrogen in these HELM engine platforms, and then also in fuel cells," Rumsey said.
