Just been diving into the hydrogen space and honestly, the opportunities here are starting to look pretty interesting. The green hydrogen companies that are actually executing—not just talking—seem positioned for some real growth ahead.

So I screened for three names that caught my attention. The criteria were pretty straightforward: companies actually involved in hydrogen production, storage, fuel cells, and related solutions, with solid revenue growth (15%+ YOY) and operational cash flow growth (10%+ YOY). Basically, avoiding the speculative stuff and focusing on companies with real fundamentals.

First up is Hyster-Yale (HY). These guys make lift trucks and material handling equipment, but here's what's interesting—they pivoted into hydrogen fuel cell power products. They were actually the first to build a hydrogen fuel cell-powered container handler, turning what used to be a fossil fuel system into a zero-emission solution. That kind of innovation got them recognized as a finalist in the World Hydrogen Awards. Looking at their numbers, FY'23 was solid. Net income hit $125.9 million (huge turnaround from a $74.1 million loss in 2022), and their cash from operations jumped to $151 million. Despite some supply chain headwinds and geopolitical noise, the business showed real resilience.

Then there's Cummins (CMI). Most people know them for diesel engines, but their Accelera division is where the real story is—they're building zero-emission solutions and hydrogen production tech. They powered the first green hydrogen passenger train in North America, which is pretty notable. Even with some regulatory charges hitting them late in the year, Cummins still grew revenue 21% YOY in 2023. Operating cash flow basically doubled, going from $1.96 billion to $3.97 billion. That's the kind of cash generation you want to see.

Last is Chart Industries (GTLS). These guys are actually a global leader in the clean energy infrastructure space—they handle cryo tank solutions, heat transfer systems, and all the equipment needed for hydrogen separation, liquefaction, and purification. They just opened a massive cryogenic tank facility in Theodore, Alabama, which should help with capacity and shipping costs. Their growth is wild—sales went from $1.61 billion in 2022 to $3.35 billion in 2023. That's 108% growth. Operating cash flow jumped from $80.8 million to $234.8 million. And they're forecasting 28-37% sales growth going forward with 52-68% EBITDA growth. That's the kind of trajectory that makes you pay attention.

What's striking about all three is that these aren't speculative plays on some distant future. These green hydrogen companies are generating real cash, growing revenues, and actually deploying hydrogen solutions right now. The infrastructure is being built, the demand is there, and the economics are starting to work. If you're thinking about exposure to this space, these are the kinds of names worth looking at before the market catches up.
