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, and
6. Blimps?

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 1960s, 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. Distributing energy across sectors and regions,
7. Providing Clean Feedstock for Industry,

According to a recent report by McKinsey (2017), hydrogen and fuel cell technology has the potential to eliminate 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
