Message definition (Sustainable energy)
The main method of producing hydrogen is [[steam methane reforming]], in which hydrogen is produced from a chemical reaction between steam and [[methane]], the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. While carbon capture and storage (CCS) could remove a large fraction of these emissions, the overall carbon footprint of hydrogen from natural gas is difficult to assess {{As of|2021|lc=y}}, in part because of emissions (including [[Gas venting|vented]] and [[Fugitive gas emissions|fugitive]] methane) created in the production of the natural gas itself.
