Scientists have developed micro-fibers that are 30 times smaller than human hair. Cloth woven out of those fibers can hold as much hydrogen per weight as current high-pressure tanks. If beads are produced instead of fibers, this material acts like a liquid and can be pumped in a manner similar to current car fuels. One of the challenges in energy production is how to handle the difference in consumption between peak hours and off-peak hours. Hydrogen could play the important role of storing excess energy in off-peak hours to have it available at peak hours. Simplifying hydrogen storage is an important enabling step in this domain.
