Toyota is continuing to push the boundaries of alternative energy solutions with the introduction of portable hydrogen cartridges.
Set to make their debut at the Japan Mobility Show Bizweek 2024, these cartridges could revolutionise the way we power hydrogen fuel cell electric vehicles (FCEVs) and more.
The compact cartridges are being pitched as a potential game changer, akin to an oversized AA battery, with wide-ranging applications for daily life and beyond.
Portable power

The concept behind Toyota’s hydrogen cartridges is simple yet innovative.
By reducing the size and weight of traditional hydrogen tanks, Toyota has made these containers portable and versatile. The automaker envisions a future where hydrogen becomes a "familiar and safe energy source," powering everything from fuel cells for generating electricity to hydrogen-powered stoves.
In collaboration with Rinnai Corporation, a leading Japanese kitchen appliance manufacturer, Toyota has even developed a hydrogen-powered cooker, highlighting the cartridges' potential as an energy source for homes.
The ability to replace or swap out hydrogen cartridges in vehicles is another compelling prospect, making the process of refuelling an FCEV as simple as changing a battery.
Beyond cars
Toyota’s vision for these cartridges extends far beyond the automotive industry. The company suggests that the portable hydrogen cartridges could serve as an energy solution for remote locations, offering power for off-grid buildings or outposts.
This aligns with a broader shift towards renewable energy and decentralised power generation, presenting hydrogen as a clean, practical option for areas with limited infrastructure.
Alongside the hydrogen cartridges, Toyota will be showcasing their hydrogen-powered GR Corolla, a vehicle that has been competing in endurance races since 2023.

The racecar represents the company’s commitment to pushing hydrogen technology to the limits, demonstrating its durability and performance potential.
Additionally, Toyota will present a sweep energy storage system that utilises batteries from end-of-life electrified vehicles.
This system, which reuses deteriorated batteries to maximise their remaining capacity, is part of Toyota’s broader effort to support renewable energy systems like solar and wind power.
According to Toyota, this system can help stabilise energy supplies and encourage the spread of renewable power sources.
