In a world of continuously warmer temperatures, a growing consensus demands that energy sources have zero, or next-to-zero, carbon emissions. That means growing beyond coal, oil, and natural gas by getting more energy from renewable sources.
One of the most promising renewable energy carriers is clean hydrogen, which is produced without fossil fuels.
It’s a promising idea because the most abundant element in the universe is hydrogen, found in 75 percent of all matter. Moreover, a hydrogen molecule has two paired atoms—Gemini twins that are both non-toxic and highly combustible.
