The economics are starting to make sense for hydrogen as a long-term energy storage medium. In this Motley Fool Live segment from "The High Energy Show," recorded on June 28, Fool.com contributors Travis Hoium and Jason Hall discuss what investors need to know. 

Travis Hoium: Going to the future of energy, we've heard a lot about this in the last two years or so. I think two years is when the hype cycle started. Will electrolyzers, this is a process of turning, typically, today you're talking about using wind or solar and then water turning that into hydrogen. So you can then use hydrogen for something else in the future. Will electrolyzers be a meaningful business, define that however you want, five years from now?

Jason Hall: I think Bloom and Plug.

Travis Hoium: Yeah.

Jason Hall: Public, as far as like the publicly traded ones are relatively far along. There's a European company that's been doing some interesting stuff they're really small that's doing some stuff. I know Linde has a partner, a privately held partner that they are working with, and I mean they do billions of dollars in hydrogen already so there's incentive there. I'm going to say yes actually, I don't even know why I'm beating around the bush. I'm going to say yes, absolutely, I think all of the electrolyzer unit sales combined could be a multi-million-dollar business as quickly as five years from now. I think it's possible.

Travis Hoium: I agree with that. I'm very bullish on the concept of hydrogen as a long-term energy storage medium. So whether that means that it goes into a ship to power the ship instead of diesel, or whether it's long-term energy storage for solar so that we can be using power from the sun here in Minnesota, where getting cheaper energy from, let's say Arizona, coming through pipelines, which people have talked about for years. I don't know what the logistics of that will be, but I think it makes sense, today, the economics are starting to make sense.
