Battery Electric Vs. Hydrogen Fuel Cell

Since the introduction of the Nissan Leaf (2010) and Tesla Model S (2012), battery-powered electric vehicles (BEVs) have become the primary focus of the automotive industry.

This structural shift is moving at an incredible rate—in China, 3 million BEVs were sold in 2021, up from 1 million the previous year. In the U.S., the number of models available for sale is expected to double by 2024.

In order to meet global climate targets, however, the International Energy Agency claims that the auto industry will require 30 times more minerals per year. Many fear that this could put a strain on supply.

“The data shows a looming mismatch between the world’s strengthened climate ambitions and the availability of critical minerals.”
– Fatih Birol, IEA

Thankfully, BEVs are not the only solution for decarbonizing transportation. In this infographic, we explain how the fuel cell electric vehicle (FCEV) works.

How Does Hydrogen Fuel Cell Work?

FCEVs are a type of electric vehicle that produces no emissions (aside from the environmental cost of production). The main difference is that BEVs contain a large battery to store electricity, while FCEVs create their own electricity by using a hydrogen fuel cell.

Let’s go over the functions of the major FCEV components.

Battery

First is the lithium-ion battery, which stores electricity to power the electric motor. In an FCEV, the battery is smaller because it’s not the primary power source. For general context, the Model S Plaid contains 7,920 lithium-ion cells, while the Toyota Mirai FCEV contains 330.

Hydrogen Fuel Tank

FCEVs have a fuel tank that stores hydrogen in its gas form. Liquid hydrogen can’t be used because it requires cryogenic temperatures (−150°C or −238°F). Hydrogen gas, along with oxygen, are the two inputs for the hydrogen fuel cell.

Fuel Cell Stack and Motor

The fuel cell uses hydrogen gas to generate electricity. To explain the process in layman’s terms, hydrogen gas passes through the cell and is split into protons (H+) and electrons (e-).

Protons pass through the electrolyte, which is a liquid or gel material. Electrons are unable to pass through the electrolyte, so they take an external path instead. This creates an electrical current to power the motor.

Exhaust

At the end of the fuel cell’s process, the electrons and protons meet together and combine with oxygen. This causes a chemical reaction that produces water (H2O), which is then emitted out of the exhaust pipe.

Which Technology is Winning?

As you can see from the table below, most automakers have shifted their focus towards BEVs. Notably missing from the BEV group is Toyota, the world’s largest automaker.

Hydrogen fuel cells have drawn criticism from notable figures in the industry, including Tesla CEO Elon Musk and Volkswagen CEO Herbert Diess.

Green hydrogen is needed for steel, chemical, aero… and should not end up in cars. Far too expensive, inefficient, slow and difficult to rollout and transport.
– Herbert Diess, CEO, Volkswagen Group

Toyota and Hyundai are on the opposing side, as both companies continue to invest in fuel cell development. The difference between them, however, is that Hyundai (and sister brand Kia) has still released several BEVs.

This is a surprising blunder for Toyota, which pioneered hybrid vehicles like the Prius. It’s reasonable to think that after this success, BEVs would be a natural next step. As Wired reports, Toyota placed all of its chips on hydrogen development, ignoring the fact that most of the industry was moving a different way. Realizing its mistake, and needing to buy time, the company has resorted to lobbying against the adoption of EVs.

Confronted with a losing hand, Toyota is doing what most large corporations do when they find themselves playing the wrong game—it’s fighting to change the game.
– Wired

Toyota is expected to release its first BEV, the bZ4X crossover, for the 2023 model year—over a decade since Tesla launched the Model S.

Challenges to Fuel Cell Adoption

Several challenges are standing in the way of widespread FCEV adoption.

One is performance, though the difference is minor. In terms of maximum range, the best FCEV (Toyota Mirai) was EPA-rated for 402 miles, while the best BEV (Lucid Air) received 505 miles.

Two greater issues are 1) hydrogen’s efficiency problem, and 2) a very limited number of refueling stations. According to the U.S. Department of Energy, there are just 48 hydrogen stations across the entire country. 47 are located in California, and 1 is located in Hawaii.

On the contrary, BEVs have 49,210 charging stations nationwide, and can also be charged at home. This number is sure to grow, as the Biden administration has allocated $5 billion for states to expand their charging networks.

Charted: The Energy Demand of U.S. Data Centers

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

As the digital economy accelerates and generative AI becomes more deeply embedded in business and daily life, the physical infrastructure supporting these technologies is undergoing a transformative explosion.

In this graphic, we use data from McKinsey to show current and projected energy demand from data centers in the United States. Data is from October 2023.

U.S. Data Centers Could Quadruple Power Demand by 2030

Today, data centers account for roughly 4% of total U.S. electricity consumption. But by 2030, that share is projected to rise to 12%, driven by unprecedented growth in computing power, storage needs, and AI model training.

In fact, U.S. data center energy demand is set to jump from 224 terawatt-hours in 2025 to 606 terawatt-hours in 2030.

YearConsumption (TWh)% of Total Power Demand
20231474%
20241784%
20252245%
20262927%
20273718%
20284509%
202951310%
203060612%

Meeting this projected demand could require $500 billion in new data center infrastructure, along with a vast expansion of electricity generation, grid capacity, and water-cooling systems. Generative AI alone could require 50–60 GW of additional infrastructure.

This massive investment would also depend on upgrades in permitting, land use, and supply chain logistics. For example, the lead time to power new data centers in large markets such as Northern Virginia can exceed three years. In some cases, lead times for electrical equipment are two years or more.

A Strain on the U.S. Grid

The U.S. has experienced relatively flat power demand since 2007. Models suggest that this stability could be disrupted in the coming years. Data center growth alone could account for 30–40% of all net-new electricity demand through 2030.

Unlike typical power loads, data center demand is constant, dense, and growing exponentially. Facilities often operate 24/7, with little downtime and minimal flexibility to reduce usage.

Visualizing China’s Battery Recycling Dominance

In 2025, China will hold 78% of pre-treatment and 89% of refining capacity.

Visualizing China’s Battery Recycling Dominance

Battery recycling is expected to become a cornerstone of the global energy transition as electric vehicles (EVs) and other battery-powered technologies become more widespread.

According to exclusive data from Benchmark Mineral Intelligence, China holds a dominant position in both the pre-treatment and refining stages of battery recycling.

Chinese Growing Dominance

Battery recycling involves two major stages. First is pre-treatment, where recycling begins. Scrap batteries are typically shredded and separated to produce a material known as black mass.

The next stage is refining, which processes black mass into valuable lithium-, nickel-, and cobalt-based chemicals for use in battery cathodes.

China’s scale, infrastructure, and early investments in battery supply chains have translated into an outsized advantage in recycling capacity.

As the largest producer and user of lithium ion batteries, the country is expected to process 3.6 million tonnes of scrap batteries in 2025, up from 1.2 million tonnes in 2022. This would account for 78% of global pre-treatment capacity, with total global capacity projected to exceed 4.6 million tonnes.

In second place is the rest of Asia, with 361,000 tonnes, followed by Europe with 416,000 tonnes. While the U.S. attempts to reduce its reliance on China in the mineral sector, North America accounts for just 196,000 tonnes.

The refining stage is even more concentrated.

China’s black mass refining capacity is projected to nearly triple, from 895,000 tonnes in 2022 to 2.5 million tonnes by 2025—representing 89% of global capacity.

Refining is critical, as it converts recycled material into high-purity, battery-grade chemicals. The rest of Asia is expected to refine 225,000 tonnes, Europe 28,000 tonnes, and North America only 21,000 tonnes. Between 2022 and 2025, China’s refining capacity is projected to grow by 179%, while North America’s is expected to surge by 425%—albeit from a much smaller base.

As global demand for EVs and battery storage rises, countries looking to build domestic recycling infrastructure must accelerate investment to reduce dependence on Chinese supply chains.
