Read This Before You Buy Fuel Cell Stocks

Recognizing paradigm shifts can be quite lucrative. Simply ask investors who, long ago, recognized the potential in e-commerce and jumped on the Amazon.com bandwagon. Currently, we are in the midst of another shift: the global transition to renewable energy.

Of course there are the usual clean-energy suspects, but probe a little deeper and you'll find that fuel cells represent another consideration. But before investors ponder hitching their wagons to a hydrogen-powered future, propelled by industry leaders like Plug Power (NASDAQ: PLUG), Ballard Power Systems (NASDAQ: BLDP), and FuelCell Energy (NASDAQ: FCEL), it's imperative to become better acquainted with the sector.

Brush up on the basics

Touted as a clean-energy solution, fuel cells, through an electrochemical reaction, convert chemical energy from a fuel source -- usually hydrogen -- into electricity, producing only water and heat as byproducts.

Whereas the majority of people most likely associate fuel cells with vehicles, like the Honda Clarity and Toyota Mirai, there's a large range of applications for the alternative energy solution. Plug Power and Ballard Power Systems, for example, provide fuel-cell solutions on the smaller scale for forklifts and drones, respectively. FuelCell Energy, on the other hand, has developed utility-scale fuel cell solutions and is currently developing a carbon capture offerring for use at large natural gas-fueled power plants.

The various shades of green

Although it may seem tempting to lump fuel-cell stocks in with other alternative-energy stocks, this would be unwise. For one, fuel-cell companies do not bear a resemblance to their renewable-energy brethren in one striking way: profitability. Solar, wind, and geothermal companies have all proven the ability to report a bottom line in the black. Fuel-cell companies, not so much.

For example, consider the performances of First Solar (NASDAQ: FSLR), a leader in solar panel manufacturing; Pattern Energy Group Inc. (NASDAQ: PEGI), an independent power producer whose portfolio includes 20 wind power facilities; and Ormat Technologies (NYSE: ORA), a vertically integrated geothermal company, in comparison to the leading fuel-cell companies over the past five years.
