The hydrogen-powered Toyota GR Yaris H2 concept showcases future potential for hydrogen – but not as a fuel cell car
Toyota has actually been among the front runners in hydrogen gas cells, through its Mirai version. But the Japanese firm additionally thinks that hydrogen could, in time, be made use of as a fuel for combustion engines – and also it has released this most recent principle showcasing the modern technology: a hydrogen-powered version of its GR Yaris hot hatchback.
The GR Yaris H2 is, basically, the follow-up to a hydrogen-powered Corolla Sport that has actually been competing in a race series in Japan. It utilizes the very same 1.6-litre turbocharged three-cylinder engine as the regular GR Yaris, yet with a changed gas supply and also injection system.
Toyota claims that given that hydrogen burns at a faster price than petrol, the modified engine delivers “great responsiveness” together with “outstanding ecological efficiency”, while likewise maintaining the “acoustic and also sensory experiences” that appeal in standard combustion engines. The system is not without discharges, but the degrees of CO2 as well as NOX generated are claimed to be lot of times less than with gas.
Similar to the Corolla, Toyota has not issued any further technological information on the engine, such as power or torque figures, or provided an efficiency contrast in between the GR Yaris H2 as well as the conventional GR Yaris. There are no instant plans for production, but Toyota states that it will continue to pursue hydrogen innovations as part of its press towards carbon neutrality.
Therefore, the company has additionally announced that it will certainly release a new generation of gas cell in January 2022, bringing 54 per cent a lot more power thickness than the current arrangement, in addition to a 25 percent weight saving and a 27 percent decrease in gas cell pile quantity.
The firm claims the modules will certainly be available in 2 shapes – cubic as well as rectangle-shaped – to make it possible for use in a bigger range of applications, including business vehicles. The modules will certainly additionally be assembled in Europe – at Toyota’s R&D center near Brussels.
The outgoing generation of fuel cell module has actually currently delivered a variety of around 400km (nearly 250 miles) in a bus, with a refuelling time of less than 10 mins.
