Biogas represents a significant advancement in sustainable fuel technology, with lifecycle assessments indicating its greenhouse gas emissions are substantially lower than those of conventional natural gas.

However, industry experts note that widespread adoption faces challenges in production capacity and securing consistent feedstock supplies.

Hydrogen fuel production presents additional complexities, particularly in its classification system and production methods. Despite hydrogen being naturally abundant, harnessing it as an energy carrier requires a lot of work, electricity and money.

The most environmentally sound approach involves water electrolysis powered by renewable energy sources – this is known as green hydrogen.

The green hydrogen process creates storable fuel by splitting water molecules into their constituent elements, effectively allowing excess renewable power to be captured and preserved for future use.

As Dennis Schulz, CEO of ITM — a British market leader in energy storage and green hydrogen production — says: “Green hydrogen will play an important role in the energy transition.”
