Think about what life would be like without energy. No refrigerators, no computers, no cars, and no cellphones! Today, most of the world’s energy comes from fossil fuels, which are nonrenewable resources ( resources that take a long time for the Earth to make) that pollute our air and land. That is why we are trying to find cleaner, renewable energy resources that can power our planet.
Hydrogen is a great renewable fuel that can be made from water. Most of the water on Earth is saltwater, so we created a device that can make hydrogen from it at a low cost. It combines the process of osmosis with the reaction of water splitting. Our data show that this device is effective and efficient, which means hydrogen could become more available in the future.
