Bosch has begun volume production of its fuel-cell power module at its Stuttgart-Feuerbach location in Germany. Nikola Corporation, based in the United States, will serve as the pilot customer with its Class 8 hydrogen fuel cell electric truck, which is scheduled to enter the North American market in Q3 2023. “Here in Stuttgart-Feuerbach, in the plant whose history goes back further than any other Bosch plant, the hydrogen future is about to happen,” said Dr. Stefan Hartung, chair of the board of management of Robert Bosch GmbH. “Bosch knows its way around hydrogen, and Bosch is growing with hydrogen.” Bosch develops technology for hydrogen production and application. By 2030, the company plans to generate sales of roughly US$5.6 billion with hydrogen technology.
The Bosch plant in Bamberg, Germany, will supply the Feuerbach factory with the fuel cell stack. Important system components, such as the electric air compressor and the recirculation blower, come from the Bosch plant in Homburg, Germany. “Bosch is one of the very few companies that are capable of mass-producing technology as complex as fuel cell stacks. We don’t just have the required systems expertise, but also the capability of quickly scaling up new developments to mass production,” said Markus Heyn, member of the Bosch board of management and chair of Bosch Mobility. Production of the fuel-cell power module is not only starting in Feuerbach, but also in Chongqing, China. The required components will come from the Wuxi plant. “Bosch is the first company to produce these systems in both China and Germany,” said Hartung. “In addition, Bosch is also planning to manufacture stacks for mobile applications in its US plant in Anderson, South Carolina. Worldwide, the company expects that, by 2030, one in five new trucks weighing 6 tons (5.4 tonnes) or more will feature a fuel-cell powertrain.
“Only with hydrogen can there be a climate-neutral world,” the company said in a statement for Bosch Tech Day 2023. “For Bosch, that is crystal-clear. The company therefore strongly advocates the establishment of a hydrogen economy and is stepping up its investments in hydrogen. Between 2021 and 2026, Bosch will have invested a total of nearly US$2.8 billion in the development and manufacturing of its hydrogen technologies. That is another US$1.12 billion than was earmarked in the investment plan for 2021 to 2024. The business opportunities for Bosch are huge, as is the effect on jobs. Even now, there are more than 3000 people at Bosch working on hydrogen technologies, more than half of them in Europe. Most of the vacancies can be filled from within the company, and especially with people who have so far worked in the Bosch powertrain business. However, the further prospects for the hydrogen business depend on the political environment. Hartung especially believes that Europe must do much more to create a counterweight to the rapid pace of developments in other regions of the world, such as the United States.”
At the event, Hartung outlined four demands of German and European policymakers. “First, we have to step up the pace of hydrogen production in the EU,” said Hartung. “Second, global supply chains have to be set up, and third, hydrogen has to be used in all sectors of the economy.” As a fourth point, he stressed the importance of quickly setting up infrastructure for distributing hydrogen in Europe.
Bosch Technology Starts With Electrolysis And Ends With The Hydrogen Engine
At the start of 2023, Bosch started constructing prototypes for electrolysis using proton exchange membranes, the reverse of the energy conversion method used in mobile fuel cells. Starting in the fall, the company intends to make 1.25-MW prototypes available for pilot applications and is on track to start volume production in 2025. Bosch is exploring several options for the use of hydrogen. Stationary solid-oxide fuel cells can be used for the distributed supply of power and heat. In a pilot project at the hospital in Erkelenz, near Cologne in Germany, Bosch wants to use this technology to achieve overall efficiency of 90%. The micropower plant there will initially run on natural gas but can be converted to green hydrogen. Apart from the fuel cell powertrain, Bosch is also working on the hydrogen engine, developing systems for both port and direct injection of hydrogen. The company said the solution is particularly suitable for heavy vehicles on long hauls with especially heavy loads. “A hydrogen engine can do everything a diesel engine does, but on top of that, it is carbon neutral. It also allows a fast and cost-effective entry into hydrogen-based mobility,” Heyn said. One major advantage is that more than 90% of the development and manufacturing technologies needed for it already exist. The hydrogen engine is expected to be launched starting in 2024. Even now, Bosch has four orders for production projects from all the major economic regions and expects six-figure unit volumes by 2030.
