With global warming and carbon emissions dominating headlines, countries are turning to hydrogen-powered technology as a secure, clean, and affordable alternative to fossil fuels.
Tracing its origins back to ancient Olympia, the Olympic torch — an eternal symbol of the hallowed sporting event — is set to shine brightly in Japan’s capital next year.
But when the flame is lit at Tokyo’s New National Stadium, it will be hydrogen fuel cells, not fossil fuels, which will sustain its fire.
The 2020 Tokyo Summer Olympic Games will be powered by hydrogen technology, from the use of hydrogen cells for the electricity supply in the Athletes’ Village to the building of over 160 hydrogen stations for fuel cell vehicles.
As an early pioneer in embracing and developing hydrogen-powered technology, Japan is on a quest to reduce emissions to less than a tenth of current levels by the year 2050.
The benefits of the technology have not gone unnoticed by the international energy community, including Japan, where hydrogen took center stage at the 2019 G20 Summit.
From rendering freight transportation carbon-free to the convenient use of portable hydrogen “capsules”, here are five reasons why hydrogen is a secure, clean and affordable alternative.
1. ZERO EMISSIONS ON THE ROADS
Heavily dependent on fossil fuels for energy, the transportation sector contributes to a staggering 20 percent of carbon dioxide emissions globally.
Hydrogen-powered vehicles could be the answer to this problem, as fuel cell vehicles, which use hydrogen gas to power an electric motor, emit only heat and water as by-products.
In China, hydrogen-powered transportation is gaining traction, with over 1,500 fuel cell vehicles currently plying the streets. Wan Gang, China’s Science and Technology Minister and the visionary leader of its electric vehicle economy, has predicted that hydrogen-powered vehicles will be the future of transportation not just in China, but also the world.
Hydrogen-powered technology can also play a significant role in decarbonizing long-haul road freight, given that heavy vehicle lorries produce almost 2.5 billion tons of carbon dioxide annually.
Global logistics giant DHL and electric vehicle start-up StreetScooter have teamed up to launch the H2 Panel Van, the world’s first 4.25-ton electric vehicle with an added fuel cell that allows it to travel up to 500 kilometers.
As part of its mission to “green” the logistics industry, DHL plans to have 100 of such fuel cell delivery vehicles on the roads between 2020 and 2021.
2. LONGER DRIVING RANGE
With a relatively short refueling time, vehicles with hydrogen fuel cells can also travel for longer on lesser energy.
In China, hydrogen-powered buses can drive beyond 500 kilometers on a full tank of hydrogen – a considerable jump from the 200 kilometers that electric buses typically achieve. Hydrogen-powered cars in Europe are traveling even farther, up to 800 kilometers or more, on a single tank.
Another example is Toyota’s leading hydrogen-powered car, the Toyota Mirai, which can complete a 3,500-kilometer journey from Northern to Southern Europe and back on just 40 kilograms of hydrogen.
While the costs of producing hydrogen have been cited as a barrier to widespread adoption, companies like Electriq Global are coming up with innovative ways to tackle the challenge.
The Israeli-Australian firm’s new hydrogen-based technology allows drivers to travel up to twice the usual distance while paying less than half the price of gasoline. The best part? The technology is entirely emission-free.
3. DECARBONIZING INDUSTRIAL SECTORS
Owing to the large amounts of fossil fuels used, the steel-making and chemicals production industries have long been regarded as emissions-heavy sectors.
But hydrogen-powered technology is slowly changing things.
The petrochemical and chemicals sector, which produced up to 1.25 gross tonnage of carbon emissions in 2017, is turning to electrolytic hydrogen as a substitute for fossil fuels.
Within the steelmaking industry, the development of breakthrough technologies has led to a large number of promising projects, including a steelmaking factory in Hamburg, which uses an innovative hydrogen-based process to produce steel with low carbon emissions.
In Sweden, steel production firm Hybrit is developing the world’s first fossil-free hydrogen-powered steel plant that aims to use biofuels to produce iron ore pellets.
As more industries embrace hydrogen energy, the cost of producing it from renewable energy could become more affordable by 2030, said the International Energy Agency in a recent report.
4. EASY TO STORE, EASY TO USE
One key benefit of hydrogen is the ease at which it can be stored, shipped, and used. This means that countries with little space for wind and solar equipment will still be able to benefit from carbon-free energy.
Energy companies are constantly finding effective ways to store and harness the potential of hydrogen. In Oxfordshire, United Kingdom, technological giant Siemens has launched the world’s first energy storage demonstrator, which can store and transport carbon fuel safely and effectively.
Hydrogen fuel is so versatile that in 2016, a Japanese research team designed and created hydrogen “capsules” that allow consumers to store hydrogen batteries in their pockets and use them for day-to-day activities.
5. SUCCESSFUL USE IN SPACE TRAVEL
Contrary to popular belief, the use of hydrogen energy is not new. Hydrogen was used by the National Aeronautics and Space Administration (NASA) as a rocket propellant and fuel cell unit to operate auxiliary power units in space since the early 1960s.
That same decade, internationally acclaimed American industrial designer Brooks Stevens launched the Utopia Concept, a series of hydrogen fuel cell propulsion cars that revolutionized the motor industry.
But the most memorable use of hydrogen has to be the Apollo moon landing missions in 1967 when NASA used 363 feet tall valves fueled by liquid hydrogen, liquid oxygen, and kerosene to power its rockets.
Named the “Saturn V” rockets, they were, and still are, considered to be the most powerful rockets ever built.
