Curious about investing in hydrogen

An article in NYTimes (May 17) piqued my interest in hydrogen as an alternative energy source. A quick search led to Global X Hydrogen ETF and Defiance Next Gen H2 ETF. Global tracks Solactive Global Hydrogen Indes; Defiance tracks Bluestar Global Hydrogen Index. I'm wondering how to get more information about the pros and cons of investing in this sector. submitted by /u/vsweeney [link] [comments]
