2 · Today, the majority of hydrogen is used by the refining and chemical industries. Demand for industrial use has tripled since 1975 and its potential as an energy transition fuel could see demand grow exponentially. Similarly, hydrogen could help decarbonize hard-to-electrify heavy mobility sectors like shipping, railways and buses.
Hydrogen and Fuel Cell Technology Basics. A scientist demonstrating a way to use sunlight to directly produce hydrogen, using a photoelectrochemical process. Hydrogen is the simplest and most abundant element in the universe. It is a major component of water, oil, natural gas, and all living matter. Despite its simplicity and abundance
Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C. Hydrogen can also be stored on the surfaces of solids (by adsorption) or
Hydrogen holds the potential to provide clean, safe, affordable, and secure energy from abundant domestic resources. In 2003, President George W. Bush announced the Hydrogen Fuel Initiative to accelerate the research and development of hydrogen, fuel cell, and infrastruc ture technologies that would enable hydrogen fuel cell vehicles to reach
For hydrogen to contribute to the energy transition, a scale-up over the next decade is critical. Learn more about McKinsey''s Oil & Gas Practice. What is needed
CLEAN FUEL: This fueling station in Burlington, Vt., uses electricity to convert water into hydrogen for powering fuel cell cars. It is part of a Department of Energy program for testing
19 · For example, green hydrogen is produced by electrolysis of water using renewable electricity, making it a clean and sustainable energy source. Blue hydrogen is produced from natural gas using
Hydrogen is an energy carrier. Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance. Hydrogen can be produced—or separated—from a variety of sources, including water, fossil fuels, or biomass and used as a source of energy or fuel.
Expensive, but getting cheaper. Conventional hydrogen and blue hydrogen cost about $2 per kilogram (though the price varies depending on where it''s produced), while green hydrogen is around twice
Hydrogen produced from fossil fuels is a versatile energy carrier and can play an important role in a transition to a low-carbon economy. Hydrogen (H 2) is the simplest and most abundant element in the universe, and it only occurs naturally on Earth when combined with other elements.
Grey hydrogen. Grey hydrogen is hydrogen produced using fossil fuels such as natural gas or coal. Grey hydrogen accounts for roughly 95% of the hydrogen produced in the world today. The two main production methods are steam methane reforming and coal gasification. Both of these processes release carbon dioxide (CO 2).If the carbon dioxide
Expensive, but getting cheaper. Conventional hydrogen and blue hydrogen cost about $2 per kilogram (though the price varies depending on where it''s produced), while green hydrogen is around twice
Hydrogen as an Energy Carrier. Because hydrogen typically does not exist freely in nature and is produced from other sources of energy, it is known as an energy carrier is a clean-burning fuel, and when combined with oxygen in a fuel cell, hydrogen produces heat and electricity with only water vapor as a by-product.
Fiona Beck, an ANU physicist and convenor of the Zero-Carbon Energy for the Asia-Pacific research initiative, a hydrogen fuel project, said there were no "technological blocks" to producing cheap

Find hydrogen fueling stations in the United States and Canada. For Canadian stations in French, see Natural Resources Canada.
This paper is devoted to treating hydrogen powered energy systems as a whole and analysing the role of hydrogen in the energy systems. As hydrogen has become an important intermediary for the energy transition and it can be produced from renewable energy sources, re-electrified to provide electricity and heat, as well as stored
Key Hydrogen Facts: Most abundant element in the universe. Present in common substances (water, sugar, methane) Very high energy by weight (3x more than gasoline) Can be used to make fertilizer, steel, as a fuel in trucks, trains, ships, and more. Can be used to store energy and make electricity, with only water as byproduct.
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water, electricity, and heat. Hydrogen and fuel cells can play an important role in our national energy strategy, with the potential for use in a broad range of applications, across virtually all sectors—transportation, commercial, industrial, residential, and portable.
Hydrogen. Hydrogen, when used in a fuel cell to provide electricity, is a zero tailpipe emissions alternative fuel produced from diverse energy sources.Currently, drivers of light-duty fuel cell electric vehicles (FCEVs) can fuel up at retail stations in less than 5 minutes and obtain a driving range of more than 300 miles. Research and commercial efforts are
Some scientists believe hydrogen energy may be a cleaner, more efficient way to power our world. Hydrogen is a naturally occurring gas, and it is the most abundant substance in the universe. (The word in Greek means "water former" because hydrogen creates water when burned.) Clean hydrogen is hydrogen produced with
Hydrogen can also serve as fuel for internal combustion engines. However, unlike FCEVs, these produce tailpipe emissions and are less efficient. Learn more about fuel cells. The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 kilograms) of gasoline. Because hydrogen has a low
Learn how hydrogen is a clean, flexible energy carrier. 2. Fuel cells can be used to power several applications. Hydrogen and fuel cells can be used in a broad range of applications. These range from powering buildings, cars, trucks, to portable electronic devices and backup power systems. Because fuel cells can be grid
Hydrogen is a versatile energy carrier, which can help tackle various critical energy challenges. Today, hydrogen is mainly used in the refining and chemical sectors and produced using fossil fuels such as coal and natural gas, and thus responsible for significant annual CO2 emissions.
