Fuel cell bus funding: What the 2026 funding call most recently subsidized
In 2026, the federal government published a funding call to support buses with alternative drive systems. For transport companies and municipalities, this meant up to 70% of the additional costs for fuel cell buses and the associated infrastructure, and 55% for a higher level of electrification. The deadline for project outlines ended on July 21, 2026.
The topic briefly and concisely
The federal funding call (BMDV) supported the acquisition and conversion of fuel cell buses until July 21, 2026.
The funding rate was up to 70% of the additional investment costs for vehicles and 40% for the infrastructure; the call ended on July 21, 2026.
Project outlines had to be submitted by July 21, 2026, in order to be considered in the competitive process.
The decarbonization of public transport is one of the central challenges for municipalities and transport companies in Germany. Rising CO2 prices and the requirements of the Clean Vehicles Directive are increasing the pressure to switch to emission-free drives. With the funding call from the Federal Ministry for Digital and Transport (BMDV), which ended on July 21, 2026, the conversion of your bus fleet to hydrogen and fuel cell technology became particularly economical. This program not only offered significant financial relief, but was also a decisive lever for achieving your climate goals. HEERO supports you as an experienced partner through the entire process – from the application to the implementation.
A retrospective of the funding landscape for locally emission-free buses
The Federal Ministry of Transport (BMV) recently published a funding call that ran from May 26 to July 21, 2026. The aim was to provide massive support to transport companies in converting their fleets to climate-friendly drive systems. Since the launch of the funding guideline in 2021, around 3,500 buses with alternative drives have already been approved. Of these, more than 1,000 vehicles are already in daily use on Germany's roads. This funding round built on these successes and was a key element in achieving Germany's climate goals. The deadline for submitting project outlines ended on July 21, 2026; a follow-up call has not been announced. The coordination of the funding guideline is handled by the experienced NOW GmbH and the project management organization Jülich (PtJ). This initiative was more than just a financial incentive; it was a clear political commitment to the future of fuel cell technology in public transport. The strategic focus on alternative drives is thus being consistently pursued.
What exactly was funded? A look at the details
The funding program was comprehensively designed to support the transition holistically. It covered a wide range of investments necessary for a successful system change. The funding rate for the acquisition of new vehicles was graduated according to the degree of electrification. It amounted to up to 70% of the additional investment costs compared to a diesel bus, otherwise 55%. A funding rate of 40% applied to the necessary charging and workshop infrastructure. The following measures were specifically eligible for funding:
Acquisition of fuel cell buses (including models with range extenders).
Purchase of pure battery buses, including trolleybuses.
The conversion of conventional diesel buses to fuel cell or battery drives, as offered by HEERO with the conversion.
Construction and expansion of the necessary charging and refueling infrastructure (hydrogen refueling stations).
Specific maintenance facilities for the new drive technologies.
This broad funding base enabled logistics companies and municipalities to build a complete ecosystem for locally emission-free operations. The 2026 funding call ended on July 21, 2026; a subsequent call has not been announced. An efficient infrastructure setup is the key to success here.
This is how the competitive application process works.
The funding was awarded in a competitive process to identify the most effective projects. Project outlines had to be submitted by July 21, 2026, via the federal government's online portal easy-Online. After this deadline, the applications were evaluated based on several criteria. These include the expected CO₂ savings, the planned application context of the vehicles, and the target electrification rate of the entire fleet. A high level of innovation and good scalability of the project were clear advantages. The approval of the selected projects took place after the adoption of the Federal Budget Act. Accompanying this, the Ministry offered an online seminar to clarify questions about the funding call. Careful preparation of the application documents is crucial to succeed in the competition. The checklist for the funding application helps to meet all requirements.
Practical example: How RVK became Europe's largest H2 bus fleet with funding
Regionalverkehr Köln GmbH (RVK) is an excellent example of the successful use of subsidies. By 2025, the company expanded its fleet to 160 hydrogen-powered buses, thereby operating the largest H2 bus fleet in the whole of Europe. This was made possible by a subsidy of 33,888,000 euros from the BMDV. This sum financed the acquisition of a total of 108 fuel cell buses of the latest generation. Specifically, the fleet was expanded by 79 solo buses and 29 articulated buses. Back in 2020, RVK already secured 7.4 million euros from the National Innovation Programme Hydrogen and Fuel Cell Technology. This example shows that even large-scale fleet transitions can be financed with the right strategy. The combination of federal funds and previous EU subsidies, such as the JIVE project, was the key to success. The electrification of an entire bus fleet is no longer a distant goal.
Economic Efficiency in Focus: TCO and the Role of Retrofitting
The high acquisition costs for new electric vehicles are often a hurdle. This is where the fuel cell bus funding 2025 came in, cushioning up to 70% of the additional costs. But there is an even more economical way: converting existing vehicles. HEERO is a leader in the circular economy with its patented conversion for Mercedes-Benz Sprinters. Instead of writing off a proven fleet, we extend its lifecycle. This not only protects the budget but also valuable resources. The conversion was also eligible for funding and significantly reduces the Total Cost of Ownership (TCO). Especially for craft businesses or companies with expensive special bodies, this is the most pragmatic solution. You keep your vehicle and still switch to a locally emission-free drive. The combination of former funding and conversion made the switch particularly economical. This is how alternative drives for buses become a smart investment.
