Zero Emission & Noise
To keep our living space healthy, we are looking for city transportation that does not pollute the environment. Both battery and fuel cell operated vehicles are clean and quiet: no emissions, no noise. The low operating temperature of Nedstack PEM fuel cells makes them a safe solution.
Low total cost of Ownership
City busses and delivery trucks with Nedstack fuel cell stacks already offer a lower cost of ownership than traditional alternatives. In particular, Nedstack-based FCEV busses have outperformed competing FC-busses on fuel efficiency, whereas the costs of hydrogen is an important contribution to the TCO. And isn’t it this total lifetime cost that actually counts? Fuel cells enable long autonomous runs, quick refuels, quick starts and stops, and require little maintenance. Therefore, they result in higher system availability and flexibility, and lower operational expense. As a result, Nedstack fuel cells contribute to a healthier and safer city environment, without any of the drawbacks of battery powered buses.
Despite all benefits of battery-operated systems, they have one major drawback: batteries get depleted and need to be recharged. That takes time, and time is not always available when there is a public time table to be met. Fuel cells powered vehicles, like those with combustion engines, are refueled in minutes and go. Nedstack PEM fuel cells also offer the benefit of quick starts and stops.
Another drawback of battery-operated vehicles is the uncertainty about their reach. Both diesel and fuel cell powered vehicles have guaranteed autonomy, which only depends on the size of their fuel tank size.
Affordable scalability of Runtime
Extending the autonomous runtime for a battery operated vehicle requires substantial investments and always has a limit. The reach of both diesel and fuel cell driven vehicles is much more scalable. A larger fuel tank size will do the job.
LPG and diesel are still widely available. However, with fossil fuel prices expected to rise in the future, one would wish for more fuel flexibility. Fuel cell powered systems, when fitted with a suitable reformer, can operate on a wide range of fuels. A single reformer can be installed at the refueling point. Currently (renewably powered) electrolyser based hydrogen refilling stations (HRS) have become widely available and are an ideal fuel source for Nedstack’s fuel cell stacks.
Low Maintenance Frequency
Nedstack fuel cells are the proven and robust answer to the high demands of city transportation. They possess unrivalled lifetimes, require little maintenance, have excellent load following characteristics and operate reliably over a range of temperatures and other environmental factors.
