The company says its electrolyzer technology can use the excess heat from heavy industries, such as steel and cement manufacturing, to produce hydrogen with less electricity. In 2021, it unveiled an electrolyzer that relies on the same technology as its power generation technology. Headquartered in San Jose, California, this green hydrogen company makes fuel cell power generation systems that can run on hydrogen, biogas and natural gas and can be adopted for utilities and the transportation industry. Here's a look at six of the best green hydrogen stocks to watch. The analysts compiled a list of green hydrogen stocks with the requisite electrolyzer technology. "What has historically been a niche market is about to ramp up in a massive way - creating plenty of opportunities for investors who want to play this theme - reflecting a potent combination of economic and policy drivers," Raymond James analysts wrote in a December report about the transition to green hydrogen. But there are companies involved with "green hydrogen," which is made with renewable energy that is used to separate water into hydrogen and oxygen using a tool called an electrolyzer. Most "gray hydrogen" is made using natural gas or coal without carbon-capture technology.


The emissions are clean, but producing the hydrogen itself isn't necessarily environmentally sustainable. It's possible with power from hydrogen fuel cells, a technology the world has had since the 1800s. Imagine flying in a plane, riding a bus or getting electricity from a local utility that emits only water vapor and warm air. These firms are in the thick of the switch from gray to green.
