Hydrogen contributes to decarbonization by acting as a clean energy carrier that contains no carbon. It is a versatile energy vector produced from various sources, making it essential for decarbonizing sectors like industrial manufacturing (steel, ammonia), long-haul trucking, maritime, and aviation. It also provides an efficient solution for multi-day or seasonal long-duration energy storage.
- Acts as a versatile, zero-carbon energy carrier.
- Crucial for decarbonizing heavy industry (steel, fertilizer) and transportation.
- Improves air quality in communities near freight corridors.
- Provides efficient solutions for multi-day and seasonal long-duration energy storage.
The Hydrogen Shot: Why This Clean Carrier Is Key to Decarbonization
The US government is pushing for clean energy. Energy Secretary Jennifer M. Granholm launched the Energy Earthshots Initiative. The first goal is the “Hydrogen Shot.” This aims to speed up the use of clean hydrogen. Scientists at Berkeley Lab lead this research. Adam Weber and Ahmet Kusoglu discuss why hydrogen matters now.
Hydrogen: An Energy Carrier, Not a Source
Hydrogen is often called an energy carrier. It is an energy vector. You must produce hydrogen from another source first. Then you store it. Finally, you convert and use it. This flexibility is a key benefit. Hydrogen can come from many sources. It works for many different applications. Unlike other fuels, hydrogen contains no carbon at all. We store energy in the hydrogen-to-hydrogen bond. This small, simple molecule makes energy storage easier.
Tackling Tough-to-Clean Sectors
The current focus on climate change accelerates the hydrogen economy. Hydrogen can decarbonize tough sectors. Experts call these areas “hard-to-decarbonize.” These include heavy industry. Hydrogen works as a reductant in steel making. It helps produce green ammonia for fertilizers. Heavy-duty transportation also benefits. Think of long-haul trucking, ships, trains, and planes. Hydrogen acts as a central molecule for thermal, chemical, and electrochemical energy.
While less efficient than batteries for short tasks, hydrogen excels at very long-duration storage.

Improving Air Quality and Environmental Justice
Hydrogen provides a cleaner pathway for many products. It helps reduce air pollution significantly. This is great news for communities near freight corridors or ports. Diesel particulate emissions hurt people in these areas most. Cleaner hydrogen fuel improves public health. Hydrogen can also democratize energy. It brings better energy options to places lacking infrastructure, like tribal lands.
The Role in Long-Duration Storage
Chemical storage is vital for long-duration needs. This means storage for multiple days or even seasons. Hydrogen is an efficient way to store energy chemically. This works best when paired with large-scale geologic storage. Berkeley Lab researchers study how to efficiently store and retrieve hydrogen in porous media. They also check its environmental impact compared to natural gas.
Addressing Research Complexity
Hydrogen devices are complex systems. The molecule is simple, but its application involves vast physics and chemistry. These processes happen at multiple speeds and scales. Handling all this complexity is a big challenge. Berkeley Lab uses advanced facilities and expertise to tackle this. Researchers collaborate across many divisions. They recognize that solving these problems requires teamwork.
