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.


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.


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: 4 Reasons Why Lithium Could Be the Next Gold Rush

Visual Capitalist has partnered with EnergyX to show why drops in prices and growing demand may make now the right time to invest in lithium.



The teaser image shows a bubble chart showing that the price of a Tesla is similar to that of other major auto manufacturers.

4 Reasons Why You Should Invest in Lithium

Lithium’s importance in powering EVs makes it a linchpin of the clean energy transition and one of the world’s most precious minerals.

In this graphic, Visual Capitalist partnered with EnergyX to explore why now may be the time to invest in lithium.

1. Lithium Prices Have Dropped

One of the most critical aspects of evaluating an investment is ensuring that the asset’s value is higher than its price would indicate. Lithium is integral to powering EVs, and, prices have fallen fast over the last year:

Feb 2023$76$71
March 2023$71$61
Apr 2023$43$33
May 2023$43$33
June 2023$47$45
July 2023$44$40
Aug 2023$35$35
Sept 2023$28$27
Oct 2023$24$23
Nov 2023$21$21
Dec 2023$17$16
Jan 2024$14$15
Feb 2024$13$14

Note: Monthly spot prices were taken as close to the 14th of each month as possible.

**Lithium carbonate (MB-LI-0029)

2. Lithium-Ion Battery Prices Are Also Falling

The drop in lithium prices is just one reason to invest in the metal. Increasing economies of scale, coupled with low commodity prices, have caused the cost of lithium-ion batteries to drop significantly as well.

In fact, BNEF reports that between 2013 and 2023, the price of a Li-ion battery dropped by 82%.

3. EV Adoption is Sustainable

One of the best reasons to invest in lithium is that EVs, one of the main drivers behind the demand for lithium, have reached a price point similar to that of traditional vehicle.

According to the Kelly Blue Book, Tesla’s average transaction price dropped by 25% between 2022 and 2023, bringing it in line with many other major manufacturers and showing that EVs are a realistic transport option from a consumer price perspective.

General Motors$52,000$53,000

4. Electricity Demand in Transport is Growing

As EVs become an accessible transport option, there’s an investment opportunity in lithium. But possibly the best reason to invest in lithium is that the IEA reports global demand for the electricity in transport could grow dramatically by 2030:

Transport Type202220252030
Buses 🚌23,000 GWh50,000 GWh130,000 GWh
Cars 🚙65,000 GWh200,000 GWh570,000 GWh
Trucks 🛻4,000 GWh15,000 GWh94,000 GWh
Vans 🚐6,000 GWh16,000 GWh72,000 GWh

The Lithium Investment Opportunity

Lithium presents a potentially classic investment opportunity. Lithium and battery prices have dropped significantly, and recently, EVs have reached a price point similar to other vehicles. By 2030, the demand for clean energy, especially in transport, will grow dramatically.

With prices dropping and demand skyrocketing, now is the time to invest in lithium.

EnergyX is poised to exploit lithium demand with cutting-edge lithium extraction technology capable of extracting 300% more lithium than current processes.

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.

In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.

Chinese Dominance

Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.

The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and Li Auto models.

CompanyCountry2023 Production
Share of Total
LG Energy Solution🇰🇷Korea108,48715%
SK On🇰🇷Korea40,7116%
Samsung SDI🇰🇷Korea35,7035%
Farasis Energy🇨🇳China16,5272%
Envision AESC🇨🇳China8,3421%

In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.

The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.

Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now effectively sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.

Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.
