Hyundai Motor Group aims to take lead in technology for future hydrogen society

Hydrogen is the most abundant element on earth and when used as an energy source, it does not generate carbon dioxide which is known to cause negative climate change. It thus has great potential as a zero-emission energy source for a variety of products. For this reason, a number of leading global companies are carrying out R&D to develop processes to produce hydrogen efficiently and cost-effectively as well as to make use of it widely.

The Hyundai Motor Group (HMG) is among these companies and has announced its Hydrogen Vision 2040 to popularize hydrogen by 2040 for ‘Everyone, Everything and Everywhere’. Hydrogen Wave represents the group’s plans for a new ‘wave’ of hydrogen-based products and technologies toward a hydrogen society.

“By developing advanced technologies and innovative systems – as well as encouraging close collaboration between public and private sectors across the globe – it is possible to make this sustainable vision a reality for all,” said the Chairman of the HMG, Euisun Chung, at the Hyundai Wave global forum online today.

He explained that Hyundai Motor Group’s vision is to apply hydrogen energy in all areas of life and industry such as homes, workplaces and factories. “The goal is to make hydrogen readily used for everyone, everything, and everywhere,” said Mr. Chung. “We want to offer practical solutions for the sustainable development of humanity and with these breakthroughs, we aim to help foster a worldwide Hydrogen Society by 2040.”

Electrification of commercial vehicle models
In the context of the auto industry, HMG revealed unprecedented plans that will see the electrification of all new commercial vehicle models – featuring fuel cell electric or battery electric powertrains, as well as the application of fuel cell systems – to all models by 2028. Other future product concepts featuring fuel cell technologies include Trailer Drone, a high-performance sportscar, and fuel cell-equipped vehicles for emergency relief and rescue missions.

Since the development of its first (Fuel Cell Electric Vehicle (FCEV) in 1998, HMG has been preparing for the future of hydrogen. In 2013, the Tucson FCEV (ix35 Fuel Cell) was introduced, opening the door to the mass production of FCEVs. Then, in 2018, the company launched the next-generation fuel cell SUV, the NEXO, with the world’s first heavy-duty fuel cell truck, the XCIENT Fuel Cell, being unveiled last year. After 2 decades of fuel cell technology development, HMG will expand its fuel cell technologies for wider applications of its vehicles, including additional mobility solutions and various energy utilization.

Bringing costs down
Fuel cell systems using hydrogen to generate electricity are not only being used commercially for vehicles today but also have the potential for deployment across diverse applications by 2040. To achieve this, HMG is planning to introduce a new generation fuel cell system in 2023 with a reduced price and volume while also having significantly improved durability and output.

Through ongoing R&D gains, engineering teams have been able to reduce fuel cell costs drastically over the last 20 years. By ensuring price competitiveness, the goal is to achieve a fuel cell vehicle price point comparable to a battery electric vehicle (BEV) by 2030. Economies of scale of hydrogen production can be realised by continuous technological innovation of fuel cell systems as well as close collaboration with other organizations and governments across diverse business areas.

Next-generation fuel cell systems
HMG has developed a series of new fuel cell systems including a new prototype of its third-generation fuel cell stack. This is a higher-powered, efficiently packaged successor to the NEXO system that is planned for market introduction in 2023. Currently still in development, the third-generation fuel cell stack has 2 power versions – 100 kW and 200 kW.

The 100 kW stack has reduced in size by 30%, making it easier to apply to different vehicle types and applications. The 200 kW version is intended for commercial vehicle applications and is similar in size to the current NEXO system, but the power output has doubled.

Fuel cell technology for high-performance vehicle applications is showcased with a concept hydrogen-powered plug-in hybrid sportscar named the Vision FK. With a maximum output of over 500 kW, the Vision FK concept can accelerate from 0 – 100 km/h in less than 4 seconds. Combining a fuel cell energy converter with a high-power, RWD, plug-in powertrain, the Vision FK aims to achieve over 600 kms in range. The prototype is being developed in partnership with Rimac Automobili of Croatia (which HMG invested around US$90 million in).

High durability stacks for commercial vehicles will achieve 500,000 kms of drive range. Furthermore, the price of the third-generation fuel cell stack will be dramatically reduced – with projections being more than 50% – which will be the key factor to achieving cost parity of FCEVs with BEVs by 2030.

HMG will continue to develop hydrogen mobility, expand the production system of fuel cells and establish infrastructures for a global hydrogen society. “The degree and frequency of environmental disasters is rising fast, and we now face a code red warning for humanity,” said Mr. Chung. “The Group seeks to offer powerful and pragmatic solutions for combatting climate change via the tremendous potential of hydrogen energy.”

HydroVILLE to showcase hydrogen vision
Following the Hydrogen Wave forum, HMG will be presenting its plans for hydrogen energy and a global hydrogen society at its ‘Hydrogen Village’ (HydroVILLE) exhibition in Goyang, Korea, this week. HydroVILLE’s various zones will illustrate the Group’s future hydrogen vision. The exhibition space features several fuel cell concepts for future mobility and power generation, including 18 models from Hyundai Motor Group affiliates such as Hyundai Motor, Kia, Hyundai Mobis, Hyundai Rotem, Hyundai Steel, Hyundai Wia and Hyundai Kefico.

Toyota to start selling second generation of Mirai hydrogen fuel-cell vehicle in late 2020

Toyota introduced its first commercially-available hydrogen-powered fuel cell vehicle (FCEV) – the Mirai – in 2014. Technically sophisticated with its advanced technology, the Mirai has served as a catalyst for increasing global awareness of how a future clean and sustainable hydrogen society might be achieved.

Now, 5 years later, after real-world usage and further developments in fuel cell technology, the second generation is due for introduction towards the end of this year. It will be available initially in Japan, North America and Europe.

At the 2019 Tokyo Motor Show, Toyota provided an early glimpse of the advances it is making across the board with the new Mirai, in terms of technical excellence, dynamic performance, and desirable design. Efficiency is still a critical area, and Toyota is targeting a 30% increase in the Mirai’s driving range (around 500 kms with the first generation model) through improvements to the fuel cell system and the use of larger on-board hydrogen tanks.

The new Mirai sits on Toyota’s latest rear wheel drive modular platform (TNGA-based) which has been engineered to accommodate different powertrains – including a hydrogen fuel cell – at the outset. It further gives the new Mirai a higher degree of body rigidity, which contributes to greater agility and responsiveness, and a lower centre of gravity, which makes for nimble, rewarding handling.

There will be three tanks – one long, two short – which together increase the fuel capacity by around one kilogram of hydrogen compared to the current model. As well as extending the potential driving range, improvements in the performance of the fuel cell system give more linear, smooth response when moving off. Handling is also said to be light and easy on winding roads.

The big change for the new Mirai’s is its exterior design, with low lines and a sleek, taut bodywork with large, 20-inch diameter wheels that together generate a powerful and distinctive look.

The interior has been conceived as a simple, modern space with a warm, comfortable ambience that adds to the sense this is a car that’s genuinely enjoyable to drive and travel in. Key elements include a 12.3-inch centre display and an instrument panel that wraps around the driver. The platform and intelligent packaging allow for five seats to be provided in place of the current Mirai’s four.

“We have pursued the goal of making a car that customers will feel they want to drive all time, a car that has an emotional and attractive design and the kind of dynamic and responsive performance that can bring a smile to the driver’s face,” said Yoshikazu Tanaka, the new Mirai’s Chief Engineer who also headed the team for the development of the first generation.

“I want customers to say ‘I chose the Mirai not just because it’s an FCEV, but because I simply wanted this car; it just happens to be an FCEV.’ We will continue our development work focusing on that feeling, and we hope that with the new Mirai, we will be a leader in helping realise a hydrogen energy society,” he added.

Although the pace of sales for Toyota’s first fuel-cell electric vehicle (FCEV), the Mirai, has not been as fast as for the Prius, which was its first mass-produced hybrid model, the carmaker is pushing ahead with development of FCEVs. It is already in the final stage of development of the next generation of the Mirai and will display a concept model at the 2019 Tokyo Motor Show this month. It is expected that the production model will look very much like the concept shown in these pictures.

“We have worked to make a car that customers will want to drive all the time, a car that has an emotional and attractive design and the kind of dynamic and responsive performance that can bring a smile to the driver’s face,” said Yoshikazu Tanaka, Chief Engineer of the first generation Mirai as well as the second generation. “I want customers to say ‘I chose the Mirai because I simply wanted this car, and it just happens to be an FCEV.’ We will continue our development work focusing on that feeling, and we hope that with the new Mirai, we will be a leader in helping to realize a hydrogen energy society.”

Improved in all aspects
The totally re-designed Mirai reflects a major step forward for FCEVs and the potential of a hydrogen society, boasting significantly greater range, improved driving performance, and an elegant, sporty design that offers increased passenger room and comfort. It will be able to accommodate 5 occupants instead of four in the current Mirai.

Launched in 2014, the first-generation of the FCEV proved the global potential of hydrogen to power clean and sustainable mobility, combining a driving range with refuelling time equivalent to conventional vehicles and no emissions but water. Since then, approximately 10,000 units have been sold globally, helping pave the way towards a hydrogen society that will reduce emissions, diversify energy sources, and generate global economic growth.

Scheduled for launch starting in late 2020, initially in Japan, North America and Europe, the second-generation Mirai is said to be much more than an eco-car, marking a new stage for FCEV technology. Improvements in fuel cell system performance and increased hydrogen storage capacity mean the new Mirai will target an increase in driving range.

The car has also been totally redesigned based on Toyota’s premium rear-wheel drive TNGA platform to combine greater agility and driving performance with a sleek and elegant exterior design. It will be presented in a newly developed exterior colour (called Force Blue Multiple Layers), that uses layers of colour to achieve exceptional brightness and depth.

Substantial improvements in driving performance
Engineered from the start to accommodate Toyota’s full range of powertrains, including hydrogen fuel cells, Toyota’s latest modular platform gives the Mirai Concept a higher degree of body rigidity, which contributes to greater agility and responsiveness, and a lower centre of gravity, which makes for nimble, rewarding handling.

Improvements to the fuel cell system go beyond increased range to offer linear, smooth response when pulling away, unity between the driver’s throttle inputs and the car’s acceleration. Handling is light and easy on winding roads, while highway driving produces an exceptional sense of power at all speeds.

Next stage of FCEV Technology
The fully-redesigned fuel cell system, including its fuel cell stack, will deliver substantially improved performance. This includes targeting a 30% increase in driving range over the current generation, thanks to increased hydrogen storage capacity, among other measures.

The Japanese government is promoting hydrogen as the fuel of the future for the country, with next year’s Olympics event serving as a starting point for the move. Its Ministry of Economy, Trade & Industry (METI) has set a target of 200,000 fuel cell vehicles on the road by 2025 and up to 800,000 by 2030. As with electrical recharging stations for hybrids, there will need to be a substantial network of hydrogen filling stations throughout the country and METI has set target of 900.
