Hydrogen
Hydrogen
Hydrogen is the lightest and most abundant of all gases, notably found almost exclusively in compounds such as water molecules (H2O) and fossil fuels (hydrocarbon). Unlike most fuels, the combustion of hydrogen releases no greenhouse gas emission, only pure water and heat, making it a desirable ‘pollution-free’ source of power. Its versatility as a clean energy carrier for large-scale storage and deployment of usable energy has emerged a promising solution in decarbonising virtually all sectors towards a global net-zero future – transportation, industrial, electricity generation and heating processes.
Industries and Applications
Welding & Metal Fabrication
Green hydrogen is a versatile fuel for creating a reducing atmosphere for heat treating and welding process in the metallurgical industry. Hydrogen is also commonly introduced with other inert gases such as argon or nitrogen to support plasma welding and cutting operations of stainless steel and other alloys. The mix allows for precise regulations of the annealing conditions, aimed at achieving a smooth and uniform surface to produce a bright glossy finish on automotive steel parts.
Transportations
Revolutionising all kinds of new opportunities in transportation and other energy-related sectors, hydrogen fuel cells play a key role in the clean renewable energy transition. Producing zero tailpipe pollution, hydrogen fuel cell vehicles (FCVs) offer a compelling sustainable solution for powering personal and commercial fleet vehicles as well as material handling equipment such as forklifts. Additionally, their robust performance to cover long distances on a single tank of hydrogen without the need for frequent refuelling are ideal for high-mileage transportation in both public transits and heavy-duty freight trucks for logistics operations.
Food & Beverage
From fuel to food, Hydrogen has found its way into the food industry. It is used to hydrogenate unsaturated fatty acids in animal and vegetable oils, converting them into solid fats for food additives such as margarine and vegetable shortening, which have a more desirable texture and shelf life.
Healthcare
Research into medical applications of molecular Hydrogen (H2 gas) or hydrogen-rich water, particularly its antioxidant and anti-inflammatory properties, is gaining attention for potential therapeutic benefits in neurodegenerative diseases like Alzheimer’s and Parkinson’s. Hydrogen is also favoured as a carrier gas in gas chromatography, a crucial analytical technique in medical and pharmaceutical research.
Electronics
In electronics and semi-conductor manufacturing, hydrogen is an efficient reducing and etching agent to help remove oxides and contaminants from silicon surfaces, ensuring high purity and reliability in semiconductor devices and LED displays.
