The “hydrogen economy” – subject of much hype in the early 2000s - is undergoing a revival.

Hydrogen could prolong the life of some pipeline and storage infrastructure in a decarbonising energy economy and play a key role in linking the gas and power sectors. With natural gas also in line as a potential feedstock for hydrogen production, Gas Matters asks whether hydrogen is the heir to natural gas’ legacy.
