"Primary energy source" is a term with a specific meaning. I'm not talking about market share. Primary energy sources do not require any type of conversion. Fossil fuels, nuclear, wind, and solar are all primary energy sources. Free hydrogen isn't found in nature. It can be made by splitting water using energy from a primary source. The catalyst described in this press release makes that process more efficient, but it still takes energy from a primary source to create hydrogen.
