HYDROGEN TECHNOLOGIES The most common element in the universe, hydrogen, has long been hailed as a promising clean fuel for the future. That future might be closer than ever thanks to massive investments made in hydrogen research and development by energy and automakers. Download PDF: https://www.marketsandmarkets.com/industry-practice/RequestForm.asp. Hydrogen and oxygen react chemically to produce electricity in hydrogen fuel cells; the only byproduct is water. Because of this, hydrogen produced using renewable energy sources like solar and wind has no emissions. Today's road-worthy hydrogen fuel cell vehicles are produced by Toyota, Honda, Hyundai, and other automakers. However, a lack of infrastructure for refueling has prevented broader adoption. Now, if slowly, that infrastructure is beginning to appear. Less than 50 public hydrogen filling stations can be found in the US at the moment, most of them are in California, where laws favor zero-emission cars. Over the next ten years, energy companies such as Shell and BP have announced plans to rapidly expand the number of hydrogen stations in the nation. Production-wise, electrolysis techniques for removing hydrogen from water are becoming more advanced. Modular electrolyzers that run on renewable energy have been developed by startups. So-called
