Hydrogen Vehicle Systems has unveiled its modular platform, designed to provide Heavy Goods Vehicle operators maximum flexibility from a single base vehicle.
The company’s tractor unit will be available with two different types of e-axle – one medium power and one high power – and with up to three hydrogen tanks, depending on the customer’s range requirements.
In addition, the hydrogen fuel cell powertrain can be specified with two different power outputs depending on the customer’s payload and mission requirements.
The modular platform is built on a fixed wheelbase, which means the vehicle’s footprint does not change, irrespective of specification.
Spacious cab in any guise
HVS’ ground-up designed vehicles have been specifically developed to maximise driver comfort while the platform is purpose built around the hydrogen powertrain. The vehicle’s design includes a suspended cab at the front and a fixed tower at the rear, housing the thermal and powertrain systems.
This platform format breaks with the industry-standard tradition of variable cab types and sizes – such as big, medium and small, and high/low-roof – and means that even the smallest variants have the same spacious cab as the largest models.
“We’re offering maximum modularity within a single base vehicle platform, and we would never have been able to achieve this level of flexibility and optimisation with a diesel-powertrain derived vehicle design,” said Pete Clarke, head of design at HVS,
“Our vehicles have been created for a fundamentally different technology within an all-new package, so every cubic millimetre has been designed afresh. We initially calculated the maximum wheelbase possible to achieve the required turning circle and manoeuvrability for the target market. The design process then began with the optimal powertrain format, around which the vehicle design was then created – ensuring that form followed function.”
Designed for optimum total cost of ownership
The modular platform allows operators to define their HGV specification relative to their operation, while simultaneously transitioning to a zero-emission fleet. HVS’ approach is to ensure that it supplies vehicles in the most appropriate form for the job requirement.
The modular platform’s flexibility is such that the trucks can easily be retrofitted with alternative modules such as additional hydrogen tanks if the fleet’s duties change or expand.
This has the effect of minimising the total cost of ownership and provides a compelling business case for early switching to CO2-free vehicles.
Remake, remodel
Vehicle platform longevity and recycling the electrochemical modules are further benefits of HVS’ modular platform. Its adaptable architecture means core electrochemical modules, including the battery and fuel cell, can be swapped out for more advanced equivalents as the technology advances. This future-proofs the vehicle and vastly increases its potential operational life, while other less-critical components, such as interior trim or body panels, can also be simultaneously refurbished by HVS when a drivetrain upgrade is performed.
Speed to market
HVS is developing new hydrogen drivetrains for its future vehicles, with a focus on delivering maximum power and range for each operational duty class. With this modular platform HVS offers the best available technology meaning that its 4×2 tractor unit provides a zero-emission range of up to 600km.
The interchangeability of the modular platform means more advanced modules can be added as the penetration of hydrogen HGVs into the market increases and technology matures and benefits from economies of scale, while early adopters will benefit from the knowledge, experience and market profile of operating hydrogen HGVs as part of the necessary transition to low carbon technology.
