A new study has shown that generating electricity on-site could bring up the climate positives of hydrogen produced from biomass while using CCUS.
The information comes from researchers at Jeonbuk National University in South Korea, who found that on-site systems deliver substantially greater benefits due to their decreased reliance on grid electricity.
This also means it can be used to cut emissions from energy-intensive operations, particularly as biomass and hydrogen use can be considered heavy industry.
The research comes as low-emissions hydrogen remains a small part of the market. Global hydrogen demand passed 100m tonnes in 2025 while low-emissions production grew by 20% to reach almost 1m tonnes, according to the International Energy Agency.
First author Ha Eun Lee, a doctoral researcher at the university, said that electricity supply strategy could significantly influence environmental performance, and that efficient processes, clean energy and responsible biomass sourcing would all be critical to achieving reliable carbon-negative outcomes.
They also noted that biomass sourcing and hydrogen production efficiency has a god influence on the environmental impact – including soil and freshwater ecosystems amongst others.
