There has been a lot of movement in the hydrogen space lately. The tech has potential for zero-emission energy, but extraction and costs are still hurdles. Here is a quick breakdown of the main players: * **Air Products** is about 80% done with their massive green hydrogen project in Saudi Arabia, aiming for 2027 production. * **Ballard Power Systems (BLDP)** reported Q3 revenue up 120% to $32.5 million, driven by bus and rail demand. * **Plug Power (PLUG)** secured financing to keep operations running and is exploring backup power for data centers. * **Bloom Energy (BE)** partnered with Brookfield Asset Management (BAM) for a $5 billion AI infrastructure deal. * **Linde** is building a plant for Shell (SHEL) but says the tech needs 5 to 7 years to mature. * **Cummins** and **FuelCell Energy** are also testing new engines and power systems. It is an interesting sector, but keep in mind many of these companies rely on government incentives and are not profitable yet. It might be worth looking at a basket of stocks or ETFs if you want exposure without picking a single winner.
