Hydrogen for transport in Stuttgart Region

The region has hilly terrain. A few main axes carry much of the traffic. Most of the settlements are also located in these narrow river valleys. While Stuttgart is by far the largest city, other towns maintain their own centrality and catchment area. Traffic is intense, both passenger and freight.

As a result, Stuttgart Region has multiple reasons to focus on innovative traffic and transport solutions. Among them are:

• The traffic situation in a heavily industrialized hilly region.
• The need to decarbonize.
• The specific importance of the regional auto and mobility industry as a pacemaker of innovation.

The specific advantage of the fuel cell

Fuel cell technology is not the only possible solution to decarbonizing. First of all, it needs hydrogen as input. This must first be produced. As a result, energy efficiency of the fuel cell technology may not match that of electric cars. On the other hand, it has some specific advantages, which make the technology specifically fit for use in transport:

• Fuel cell technology needs no batteries. This saves weight and resources.
• Hydrogen is rather lightweight. A tank load allows for similar operation range as that of petrol or diesel tanks.
• Loading is quick and rather easy. From the viewpoint of the user, it can be compared to the fuelling of combustion engines.

Thus, fuel cells appear as a feasible answer for heavy vehicles or vehicles that carry heavy payloads, especially when they make many miles and have no time for battery loading.

The industry is ready to deliver mid-size fuel cell trucks from next year. It will still produce these trucks in rather small batches, but they are now based upon well-tried components and can no longer considered as experimental. Larger trucks will likely follow soon.

The current demand for fuel cell vehicles

This is the point when the “early adopters” get interested: People with an affinity to technical progress. They want to be part of the ongoing developments. Just as logistics companies in Stuttgart Region bought the first trucks at the end of the 19^th century, when employing a horse cart still was the economically superior alternative. But these companies had all the necessary experience to go for the new technology in big scale when its time was ready.

Then there are companies with a specific policy to be environmentally friendly. They can document their commitment by employing innovative transport technology early on.

Last not least there is an opportunity to start fleet conversion with public bus companies and municipal utility services. These fleets are quite big and allow the integration of first fuel cell trucks. Orders from public services can help to create a critical mass for the production of components. The result is a surge in reliability and a sharp drop in prices. In addition, these public fleet owners run their vehicles locally. They do not depend upon a national infrastructure network.

As a result, more and more regional municipalities, committed ecologists, and early adopters opt for fuel cell technology. Apparently, this will lead to the build-up of significant hydrogen fleets in the coming years.

The strategy of Stuttgart Region

Stuttgart Region supports hydrogen filling stations. So far, the whole region of 179 municipalities has just a handful of these stations. Certainly not enough for general commercial use of fuel cell technology. However, with one or two additional stations in strategic locations, a significant share of regional freight transport can already find sufficient opportunities.
