The Evolution of Hydrogen: From the Big Bang to Fuel Cells

Published

It all started with a bang…the big bang!

The explosive power of hydrogen fueled a chain reaction that led to the world we have today.

Now this power is being deployed on Earth to supply the energy needs of tomorrow.

Visualizing the Power of Hydrogen

Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association, and it outlines how hydrogen and fuel cell technology is harnessing the power of the universe to potentially fuel an energy revolution.

The Evolution of Hydrogen: From the Big Bang to Fuel Cells

What is Hydrogen, and How’s it Used?

With one proton and one electron, hydrogen sits at the very beginning of the periodic table.

Despite hydrogen being the most common molecule in the universe, it is rarely found in its elemental state here on Earth. In fact, almost all hydrogen on the planet is bonded to other elements and can only be released via chemical processes such as steam reforming or electrolysis.

There are five ways hydrogen is being used today:

  1. Building heat and power
  2. Energy storage and power generation
  3. Transportation
  4. Industry energy
  5. Industry feedstock

However, what really unleashes the power of hydrogen is fuel cell technology. A fuel cell converts the chemical power of hydrogen into electrical power.

Hydrogen Unleashed: The Fuel Cell

In the early 1960’s, NASA first deployed fuel cells to power the electrical components of the Gemini and Apollo space capsules. Since then, this technology has been deployed in everything from the vehicle you drive, the train you take, and how your favorite products are delivered to your doorstep.

Nations around the world are committing to build hydrogen fueling stations to meet the growth in adoption of fuel cell technology for transportation.

Hydrogen: A Green Energy Solution

Hydrogen fuel and fuel cell technology delivers green solutions in seven ways.

  1. Decarbonizing industrial energy use
  2. Acting as a buffer to increase energy system resilience
  3. Enabling large-scale renewable energy integration and power generation
  4. Decarbonizing transportation
  5. Decarbonizing building heat and power
  6. Distribution energy across sectors and regions
  7. Providing clean feedstock for industry

According to a recent report by McKinsey, hydrogen and fuel cell technology has the potential to remove six gigatons of carbon dioxide emissions and employ more than 30 million people by 2050, all while creating a $2.5-trillion market.

This is technology that can be deployed today, with the potential to transform how we live and power our economies in a sustainable way.

Visualizing Saudi Aramco’s Massive Oil Reserves

Saudi Aramco controls 259 billion barrels worth of oil and gas reserves, which is unmatched by any other company globally. This is a key factor in the company’s massive $1.8 trillion valuation.

To illustrate that, this chart compares the proved reserves of major oil companies as of 2022. Data was compiled by Statista from various company reports.

Crown Jewel

Saudi Aramco is the national oil company of Saudi Arabia. As of 2024, it is the sixth-largest company in the world by market capitalization.

Its oil reserves are over four times bigger than the reserves of all the other six companies on our list combined.

CompanyProved reserves (billion barrels of oil equivalent)
Saudi Aramco258.8
ExxonMobil17.7
Chevron11.2
Total Energies10.2
Shell9.6
BP7.2
Eni6.6

Behind Saudi Aramco, American company ExxonMobil comes in second with 17.7 billion barrels of oil equivalent, followed by another American company, Chevron, with 11.2 billion barrels of oil equivalent.

Saudi Aramco produces 9 million barrels of oil a day, more than any other firm and nearly a tenth of the world’s total.

In addition, the state-run oil giant is the world’s most profitable company, generating $722 billion in profits between 2016 and 2023.

Saudi Aramco is also expected to play a big part in Saudi Arabia’s plans to diversify its economy and reduce oil dependence. Recently, Saudi Arabia’s Crown Prince Mohammed Bin Salman confirmed that the kingdom is in talks to sell a 1% stake in the state oil giant, which could help fund the country’s projects in clean energy and technology.
