Electrolysis
<p>Hydrogen can also be produced using electricity, through electrolysis of water.</p>
<p>An electric current is used to split water (H2O) into oxygen (O2) and hydrogen (H2).</p>
<p>This method is not as cost-effective as using fossil fuels.</p>
<p>Hydrogen produced by steam methane reforming costs around €1.5 per kilogram at the plant gate (excluding distribution costs), triple the cost of natural gas.</p>
<p>Hydrogen produced using electrolysis is currently around four times more expensive, even before the cost of the electricity required is factored in</p>
