What are the different methods of hydrogen production?

different methods of hydrogen production are numerous, depending on the source, whether the final product should be a pure hydrogen or some kind of hydrogen compound and what their intended use is. Creating hydrogen fuel for rockets or compressed cars made of liquid fuel cells can be made by a relatively simple and well -known electrolysis process, water distribution into charged oxygen and hydrogen atoms by electric current through it. Other Forms of Hydrogen Generation With and Water-Based Medium Include hydrolysis using ammonia borane, and modified thermochemical thermolysis, Where sulfur-iodine is intraced to produce hydrogen in a nuclear reactor and the sulfur-iodine compound Use.

Solid Oxide Fuel Cells (SofC) That The Electricity Are Another alternative-Energy Option That Both Usees and Produces Hydrogen Compounds in the process without required liquid water. They work as batteries, besides their inputs can be natural gas and outGrade of carbon dioxide and electricity. There are many variations on solid fuel cells that most include the use of high temperatures and some expensive heavy metal, such as platinum. The new form of hydrogen fuel cell uses water and replaces a much cheaper metal metal for platinum and is 70 times cheaper than the use of platinum while capable of operating seawater.

Much slower hydrogen generation methods include the use of biological processes such as fermentation, and dark fermentation that does not require the presence of light. Microbial reactions, called electrohydrogenesis, can generate hydrogen from waste water. The use of plants such as algae for hydrogen production is also evolving. In 2005, researchers will bring algae in the National Renewable Energy Laboratory (NREL) in the US project, which their hydrogen production project brought to $ 2.80 USD (USD) per kilogram, which is KONKurgently with gasoline.

Another new method for generating hydrogen is the use of electrical output of solar cells. The cells of solar concentrators direct electricity to the solids, which operates at a high temperature, exceeding 2,012 ° Fahrenheit (1,100 ° Celsius). 50% of solar energy is expected to be converted into an equivalent value into hydrogen energy. This is examined for hydrogen production, as costs could be up to $ 0.85 USD (USD) per watt, comparable to the efficiency of energy systems generated by wind. Many low-cost, low-technical or high-speed, high-tech resources can produce hydrogen production, while current research is today's practical alternative energy, not in the distant future.
