The 2024 Paris Olympics claims to chop carbon emissions by 50% in comparison with the 2012 London Olympics. Along with offering vegan meals for athletes and never utilizing air con within the athletes’ village, the occasion has adopted Toyota’s zero-emission hydrogen-powered car (additionally referred to as hydrogen fuel-cell car or HFCV), the Mirai, because the official car of the video games. Nevertheless, some students have identified that present HFCVs aren’t truly eco-friendly. Who is true? On this Kwiksure article, we clarify the function of HFCVs on the Paris Olympics, and the adoption of such automobiles in Hong Kong.
Low Carbon Olympics
To realize carbon emissions discount targets, the Paris Olympics use 500 Mirai HFCVs supplied by Toyota as Olympic automobiles, transporting athletes, workers, volunteers and others from varied nations through the Olympics and Paralympics. Along with the Mirai, Toyota has additionally deployed its most eco-friendly low-carbon fashions, together with pure electrical automobiles (EVs), plug-in hybrids, and hybrids. After the Olympics, the Mirai automobiles shall be reworked right into a hydrogen-powered taxi fleet in Paris.
Nevertheless, not way back 120 scientists, engineers, and students from universities comparable to Cambridge and Oxford issued a public attraction calling upon the Paris Olympics to withdraw the Mirai because the official car of the Video games. The reason being that at present, as a lot as 96% of the hydrogen used is produced from fossil fuels comparable to methane, which additionally produce big portions of carbon emissions within the conversion course of, making it even much less eco-friendly than EVs. Nevertheless, Toyota said that the hydrogen gas used on the Paris Olympics is derived from renewable sources comparable to water and natural supplies.
What are Hydrogen-powered Automobiles?
Hydrogen is a chemical component and a element in lots of pure compounds, together with water. Many individuals imagine that hydrogen-powered automobiles use hydrogen fuel as a gasoline alternative. Nevertheless, that is an oversimplification.
In a hydrogen-powered automobile, the hydrogen fuel saved within the storage tank is transported to the gas cell, the place it reacts chemically with the battery to supply electrical energy, which powers the motor to drive the automobile–thus the title ‘hydrogen fuel-cell automobiles’ or HFCVs. HFCVs mix the traits of conventional gasoline automobiles and electrical automobiles. You’ll be able to consider the hydrogen as gasoline and the gas cell because the engine cylinders, with their mixture producing {the electrical} energy that drives the motor.
Within the course of, solely water and warmth are produced, with out producing polluting gasses or substances the way in which gasoline automobiles do. Furthermore, a couple of minutes’ price of refueling is sufficient to energy the car for lots of of kilometers. All these make hydrogen essentially the most eco-friendly and possible car gas.
Shortcomings of Hydrogen as a Gasoline
Hydrogen fuel is corrosive and extremely flammable, and this makes its transportation tough and expensive, leading to a really sluggish charge of enhance within the variety of refueling stations. Primarily based on information from Taiwan’s Automotive Analysis and Testing Heart, as of the tip of 2023, there have been solely 921 hydrogen refueling stations globally, they usually had been primarily present in Germany, South Korea, and Japan. Moreover, since their manufacturing is small in scale and includes handbook steps, hydrogen gas cells are expensive to fabricate. One more essential facet is the hydrogen storage tank, which takes up a big quantity of area. For automobiles with comparatively restricted area, that may be one other problem.
Introducing 4 Hydrogen-powered Automobiles
Toyota Mirai
For the reason that launch of the primary technology in 2014, Toyota has been actively creating hydrogen-powered automobiles and launched the second-generation Mirai in 2020. The brand new technology makes use of the TNGA-L platform, and produces 182 ps of energy and 300 Nm of torque. The automobile has 3 hydrogen storage tanks for a complete quantity of 141 liters, which is sweet for a most vary of about 650 km. The refueling will be accomplished in 5 minutes. It’s price mentioning that in August 2022, Toyota managed to drag 1,360 km from only one tank of hydrogen, setting a Guinness World File.
Hyundai Nexo
Following the ix35 and Tucson, Nexo is Hyundai’s third HFCV, persevering with the SUV type custom. The Nexo has a most energy of 161 ps and most torque of 395 Nm. The automobile has a gas storage capability of 156 liters and a variety of about 611 km. By way of tools, the automobile includes a digital instrument panel, blind-spot picture show, central display, and extra, which make the automobile fairly superior for a product launched in 2018. The producer has additionally introduced {that a} new technology Nexo shall be unveiled subsequent yr, which we count on will provide much more options and even higher efficiency.
Honda CR-V e:FCEV
Honda formally introduced its first hydrogen-powered car, the CR-V e:FCEV, earlier this yr. The brand new automobile relies on the sixth technology CR-V, and is the primary mannequin within the North American market to mix hydrogen gas cells and plug-in hybrid expertise. The brand new automobile was launched out there in July by way of a leasing program. The CR-V e:FCEV has a single motor module on the entrance axle, offering a most energy of 176 ps and 311 Nm in peak torque. Developed in collaboration with Normal Motors, the gas cell can present a variety of as much as 600 km.
BMW iX5 HYDROGEN
The BMW iX5 Hydrogen makes use of the fifth technology eDrive electrical drive system with a gas cell developed in collaboration with Toyota. It boasts a most energy of 406 ps, with the producer claiming a 0 to 100 km/h time of lower than 6 seconds. Though the iX5 Hydrogen has been exhibited and test-driven all over the world, and the primary batch of 100 models have been bought to pick prospects, the producer has said that they won’t go forward with mass manufacturing simply but. The iX5 HYDROGEN is anticipated to enter mass manufacturing in 2026 on the earliest.
Adoption of Hydrogen Gasoline-Cell Automobiles in Hong Kong
In June 2024, the Hong Kong authorities introduced the ‘Technique of Hydrogen Growth in Hong Kong,’ focusing primarily on the business functions of hydrogen vitality. This contains the introduction of the primary hydrogen fuel-cell double-decker bus (Citybus route 20) earlier this yr, and plans to check 3 hydrogen fuel-cell road sweepers by the tip of the yr. Different trial tasks embody bus firms constructing hydrogen refueling stations at depots, and MTR testing hydrogen-powered trains. Furthermore, Hong Kong’s first public hydrogen refueling station is anticipated to open in Yuen Lengthy by the tip of this yr. Despite the fact that HFCVs aren’t but obtainable on the market domestically, this alerts we are able to count on to see these automobiles to be launched within the close to future.
