Scientists are exploring the bottom of the Arctic Ocean. They are going more than 1,000 feet below the water. They want to find tiny living things called bacteria. These bacteria live in very cold and dark places. These places are called cold seeps. In these areas, the bacteria produce natural hydrogen. This is a special process. Plants use sunlight to make energy, but these bacteria use gases like methane. They do not need light to live.
Hydrogen is very important for the future of energy. It is the most common element in the universe. It makes up 90 percent of all atoms. Today, finding natural hydrogen is difficult. Most ways to get hydrogen use a lot of energy. If scientists can use the hydrogen from these bacteria, it will change how we make fuel. This could be a clean way to get energy.
This new energy could help heavy industries. Small cars can use batteries, but big ships and airplanes need more power. Hydrogen can be a clean alternative for these large machines. This will help reduce carbon emissions around the world.
However, there is a problem. The Arctic Ocean is changing quickly because of climate change. These changes are a threat to the bacteria and their homes. Scientists are worried. The bacteria might disappear before we understand them. We must study these microbes quickly. The mission is to learn how these tiny organisms make hydrogen. If we succeed, we can find a better way to power the world.
