Hydrogen is renewable in the sense that the fossil fuels we use
are hydrocarbon compounds. When we burn them, the hydrogen is
liberated in the form of water vapors or hydrogen compounds. These
vapors then mix with various gases in the atmosphere to form other
compounds like nitric acid, etc. It then comes down with the rain
and is deposited on the earth. It thus stays in the system only.
Unlike fossil fuels, the hydrogen can be extracted whenever
required (fossil fuels need millions of years to produce). Hence
hydrogen is considered renewable.
At the same time, the energy required to separate hydrogen from
the compounds it is a part of often comes from nonrenewable
sources, including fossil fuels. Hydrogen does not exist in its
elemental state naturally, it is almost always found in compounds
like water, so the compound must be broken up by electrolysis or
some other means, which requires energy. Research into solar
powered electrolysis and hydroelectric powered electrolysis has
been done, but it's not yet viable on a large scale.
Hydrogen has been produced on a large scale by steam methane
reforming. This is not renewable because it involves using methane
(a fossil fuel) and getting it to incredibly high temperatures by
using more fossil fuels. In some cases around 70% of the gasses
produced were not hydrogen but carbon based compounds.
