Virtually a 3rd of the pure gasoline fuelling UK houses and companies could possibly be changed by hydrogen, a carbon free gas, with out requiring any modifications to the nation’s boilers and ovens, a pioneering research by Swansea College researchers has proven.
Over time the transfer might reduce UK carbon dioxide emissions by as much as 18%.
Pure gasoline is used for cooking, heating and producing electrical energy. Home gasoline utilization accounts for 9% of UK emissions. In an effort to scale back annual carbon emissions, there’s presently a concerted effort from researchers worldwide to offset our utilization of pure gasoline.
Enriching pure gasoline with hydrogen is a method ahead. Experiments have proven that modern-day gasoline home equipment work safely and reliably with hydrogen-enriched pure gasoline because the gas. It’s already utilized in components of Germany and the Netherlands, with a £600m government-backed trial within the UK going down this yr.
Pure gasoline naturally accommodates a small amount of hydrogen, though present UK laws restricts the allowed proportion to 0.1%.
The query the Swansea crew investigated was how far they might improve the share of hydrogen in pure gasoline, earlier than it grew to become unsuitable as a gas, for instance as a result of the flames grew to become unstable.
The crew, Dr Charles Dunnill and Dr Daniel Jones on the College’s Power Security Analysis Institute (ESRI), discovered:
- An enrichment of round 30% is feasible, when numerous instability phenomena are taken under consideration
- Increased percentages make the gas incompatible with home home equipment, on account of hydrogen’s comparatively low power content material, its low density, and a excessive burning velocity.
- 30% enrichment by hydrogen however equates to a possible discount of as much as 18% in home carbon dioxide emissions;
The analysis was printed by the Royal Society of Chemistry.
Dr Charles Dunnill of the Power Security Analysis Institute at Swansea College stated:
“As much as 30% of the UK’s gasoline provide may be changed with hydrogen, while not having to change folks’s home equipment.
As a low carbon home gas, hydrogen-enriched pure gasoline can reduce our greenhouse gasoline emissions, serving to the UK meet its obligations below the 2016 Paris Local weather Change Settlement.
Hydrogen-enrichment could make a distinction now. Nevertheless it might additionally show a beneficial stepping-stone in direction of a future, pure hydrogen, zero carbon gasoline community.”
Notes to editors
The analysis was printed by the Royal Society of Chemistry in “Sustainable Power and Fuels“,
30% hydrogen enrichment and a possible 18% drop in carbon emissions: the distinction between the 2 percentages arises from the truth that hydrogen-enrichment lowers the calorific content material of the gas, necessitating the next quantity of gasoline for a given power output.
The analysis was supported by the Welsh Authorities Sêr Cymru Program, FLEXIS, which is partially funded by the European Regional Improvement Fund, and the King Saud College in addition to by the Welsh Authorities via the Sêr Cymru Chair for Low Carbon Power and Surroundings.

Swansea College is a world-class, research-led, twin campus college. The College was established in 1920 and was the primary campus college within the UK. It at the moment provides round 350 undergraduate programs and 350 postgraduate programs to circa 20,000 undergraduate and postgraduate college students.
The College’s 46-acre Singleton Park Campus is situated in stunning parkland with views throughout Swansea Bay. The College’s 65-acre science and innovation Bay Campus, which opened in September 2015, is situated a number of miles away on the jap method to town. It has the excellence of getting direct entry to a seashore and its personal seafront promenade. Each campuses are near the Gower Peninsula, the UK’s first Space of Excellent Pure Magnificence.
Swansea is ranked the highest college in Wales and is at the moment The Instances and The Sunday Instances ‘Welsh College of the Yr’ for 2017. Additionally it is ranked inside the prime 300 finest universities on the earth within the Instances Increased Training World College rankings.
The outcomes of the Analysis Excellence Framework (REF) 2014 confirmed the College has achieved its ambition to be a prime 30 analysis College, hovering up the league desk to 26th within the UK, with the ‘largest leap amongst research-intensive establishments’ (Instances Increased Training, December 2014) within the UK.
The College has bold growth plans because it strikes in direction of its centenary in 2020, because it continues to increase its international attain and realising its home and worldwide ambitions.
