BMW and Toyota's Hydrogen Car Gamble: A Deep Dive into Their Joint Venture

The Hydrogen Car Persistence: BMW and Toyota's Bold Move

In a surprising turn of events, BMW and Toyota are intensifying their efforts in the hydrogen fuel cell vehicle market. This move comes at a time when many other automakers are shifting their focus primarily to battery electric vehicles (BEVs). Let's examine the details of this partnership and what it means for the future of automotive technology.

A Brief History of Hydrogen Vehicles

Hydrogen-powered vehicles have been in development for over three decades, with billions of dollars invested in research and development. Despite this long-standing effort, consumer adoption has been minimal. The BMW iX5 and Toyota Mirai, both hydrogen fuel cell vehicles, have struggled to gain traction in the market.

BMW's Ambitious Outlook

BMW executives have made bold predictions about the future of hydrogen technology. Some have publicly stated their belief that by 2040, hydrogen-powered vehicles will be the primary means of transportation worldwide. This optimistic view stands in stark contrast to current market trends, which show a growing preference for battery electric vehicles.

The BMW-Toyota Alliance

By joining forces, BMW and Toyota aim to:

1. Compete with Chinese automakers
2. Challenge the dominance of electric cars
3. Potentially outperform Tesla

This partnership represents a significant commitment to hydrogen technology from two major players in the automotive industry.

The Current State of Electric Vehicle Sales

While BMW and Toyota are doubling down on hydrogen, it's important to note that electric vehicle sales continue to grow globally. In fact, worldwide EV sales have increased by 23% this year alone. This growth contradicts the narrative that EV sales are slowing, which is often used to justify continued investment in hydrogen technology.

The Hydrogen X5: A New Chapter

As part of their collaboration, BMW and Toyota plan to produce a hydrogen-powered X5. This vehicle is expected to hit the market next year, signaling a continued commitment to fuel cell technology despite the lukewarm reception of previous models.

Other Automakers' Stance on Hydrogen

Most legacy car manufacturers have scaled back or abandoned their hydrogen vehicle programs. Even Hyundai, once a strong proponent of fuel cell technology, has reduced its focus on hydrogen cars. This makes BMW and Toyota's continued investment all the more notable.

The Honda-GM Partnership

It's worth mentioning that Honda and General Motors also have a joint venture focused on manufacturing hydrogen vehicles. However, they have kept this partnership relatively quiet, possibly due to investor skepticism about the technology's viability.

The Economics of Hydrogen Vehicles

One of the major challenges facing hydrogen fuel cell vehicles is the high cost of components and maintenance. For example:

• Hydrogen tanks and fuel cell systems are extremely expensive.
• Replacing a hydrogen tank can cost more than the vehicle itself. One European owner reported a quote of $105,000 for a tank replacement.

These high costs make it difficult for hydrogen vehicles to compete with battery electric vehicles on a total cost of ownership basis.

The Infrastructure Challenge

A key reason for the lack of popularity of fuel cell vehicles is the scarcity of refueling infrastructure. Some little-known facts about hydrogen refilling stations include:

• Many stations can only service about 50 cars before needing to be resupplied.
• This limitation makes it economically challenging to operate hydrogen refueling stations.
• Several refueling stations have closed due to lack of profitability.

Environmental Concerns

Contrary to the "clean energy" image often associated with hydrogen, the current production methods are not environmentally friendly:

• Approximately 94% of hydrogen fuel worldwide is produced using fossil fuels, particularly natural gas.
• This production method significantly undermines the environmental benefits often touted by hydrogen proponents.

BMW and Toyota's Strategy

Despite these challenges, BMW and Toyota are pressing forward with their hydrogen plans:

1. Toyota will supply BMW with hydrogen components, including tanks and fuel cell systems.
2. BMW will integrate these components with its own EV technologies and drive systems.
3. The companies aim to reduce development and production costs through this collaboration.
4. They plan to improve hydrogen supply infrastructure across Europe.

BMW's Hydrogen Vehicle Lineup

BMW is not limiting itself to a single hydrogen model. The company has plans for multiple hydrogen fuel cell vehicles, including:

• The fuel cell iX5
• Additional models yet to be announced

The Production Process

BMW's approach to producing hydrogen vehicles is noteworthy:

1. Regular X5s are built in the United States.
2. These vehicles are then sent to BMW's research and innovation center in Munich.
3. The SUV's floor is replaced with a new floor containing two large hydrogen tanks.
4. An integrated drive unit with an electric motor, battery, transmission, and power electronics replaces the combustion engine.

This process essentially turns a conventional X5 into a hydrogen-powered vehicle, a method that some critics describe as a "Frankenstein" approach to vehicle manufacturing.

Safety Concerns

The safety of hydrogen vehicles is a topic of debate:

• The placement of large hydrogen tanks in the vehicle's floor raises questions about crash safety.
• Compared to modern electric vehicles, which have proven to be very safe, hydrogen vehicles face additional scrutiny.
• The high pressure required to store hydrogen (often around 700 bar or 10,000 psi) adds another layer of safety concern.

The Future of Automotive Technology

As BMW and Toyota invest heavily in hydrogen, it's important to consider the rapid advancements in battery electric vehicle technology:

• New battery technologies, such as CATL's condensed batteries, offer energy densities of 400 Wh/kg.
• These advancements could lead to electric vehicles with ranges well over 600 miles (1,000 km).
• Charging speeds of up to 600 kW are already available in some markets, allowing for extremely fast charging times.

Given these developments, the advantages of hydrogen fuel cell vehicles over battery electric vehicles become less clear.

Legal Challenges

The adoption of hydrogen vehicles has not been without legal issues:

• Toyota is facing a class action lawsuit from Mirai owners.
• Customers claim they were misled about the practicality of refueling their vehicles.
• The limited range and scarcity of refueling stations have made owning a Mirai challenging for many customers.

Industry Reactions and Speculations

The automotive industry and financial sectors have mixed reactions to the continued investment in hydrogen technology:

• Some view it as a necessary diversification of zero-emission technologies.
• Others see it as a misallocation of resources that could be better spent on improving battery electric vehicles.
• There's speculation that Warren Buffett's decision to sell his entire stake in General Motors might be related to GM's ongoing investment in hydrogen technology with Honda.

The Sunk Cost Fallacy

One perspective on BMW and Toyota's continued investment in hydrogen is the sunk cost fallacy:

• Both companies have invested billions in hydrogen technology over the years.
• There may be a reluctance to abandon these investments, even if the market signals suggest it might be wise to do so.
• This behavior is often seen in businesses that have committed significant resources to a particular technology or strategy.
