Hydrogen, often touted as the holy grail of clean energy, has made strides in various sectors, from automobiles to industrial applications. But now, it’s not just cars and trucks that are benefiting from this abundant and eco-friendly resource. Hydrogen has found its way into the world of e-bikes and scooters, offering an innovative and sustainable alternative for personal transportation.
Hydrogen has been hailed as a boundless source of affordable and clean energy for years. Unlike conventional fossil fuels, hydrogen burns without producing harmful carbon dioxide emissions, making it an environmentally friendly choice. Moreover, the use of hydrogen has the potential to reduce our dependence on lithium and rare earth elements, which are essential components in battery production and are often subject to supply chain vulnerabilities, primarily driven by China’s mining monopoly.
In contrast to electric vehicles that rely on batteries, hydrogen-powered vehicles operate with a fuel cell and a tank for liquid hydrogen. This distinction makes hydrogen an appealing option in the quest for sustainable energy solutions. However, despite its theoretical promise, several challenges persist, both at the technological and distribution levels.
To achieve true sustainability, hydrogen production must be carried out using renewable energy sources, creating a self-reinforcing cycle of environmental benefit. The question remains when we will see the development of production, storage, and distribution technologies that can compete with traditional fossil fuels. Nonetheless, progress is being made, starting from the grassroots level – even with a bicycle.
Hydrogen bicycles are becoming a reality. These unique bikes feature a distinct “water bottle” on their frames, filled with liquid hydrogen that can be produced right at home. Several companies are at the forefront of developing small-scale home systems for hydrogen production and storage, making it accessible and safe for personal use. These systems are compact, not much larger than a standard trolley bag, and promise to revolutionize personal transportation.
One such innovator is China’s Youon, which offers a portable container weighing 18 kg, housing a 40-liter tank that uses electrolysis to produce liquid hydrogen. Powered by solar energy, this system can be seamlessly integrated with city bikes, making it a valuable addition to bike-sharing services in Southeast Asian metropolises. In just 10 seconds, the tank can be refilled, allowing the bike to reach speeds of up to 23 km/h and providing a range of 50-60 km. With competitive pricing and virtually no charging costs, these bikes are set to significantly impact the market.
Germany’s Linde, an industrial automation company, has developed a similar bicycle equipped with an electrolysis system. Instead of relying on solar power, this system can be found in public roadside towers and utilizes wind or biogas energy sources. Impressively, just 34 grams of hydrogen can power the bike for up to 100 km, offering a sustainable and efficient mode of transportation.
In France, Alpha Neo has recently entered production with its aesthetically pleasing and functional hydrogen-powered bike. However, it plans to rely on hydrogen filling stations, which are still scarce in Europe.
Meanwhile, Norway is making strides in hydrogen production with the commissioning of the world’s largest electrolyzer at the Herøya plant. Capable of producing 100 kilograms of pure hydrogen per hour, this plant will serve various industrial purposes, from hydrocarbon refining to fertilizer production.
Toyota, known for its commitment to hydrogen technology, has partnered with Woven Planet Holdings to develop a portable hydrogen cartridge measuring just 40 cm x 18 cm. Weighing a mere 5 kg, this mini-bottle can be easily transported and used on scooters and other small electrical devices. It promises to extend hydrogen’s reach to remote and challenging locations, particularly during emergencies.
Hydrogen-powered bikes represent a significant step toward a cleaner and more sustainable future for personal transportation. As technology continues to advance and infrastructure develops, these bikes could become a practical and eco-friendly option for commuters, offering an alternative to traditional gasoline-powered vehicles and electric bikes. While challenges remain, the innovation and progress in this space are undeniable, showcasing the potential of hydrogen as a game-changer in the world of mobility.
