Sentences with phrase «using liquid hydrogen»

NASA can use existing capabilities and lower development costs by using liquid hydrogen and liquid oxygen (lox) for both the core and upper stages.

The blue ovals (pictured above left) are residue from the main engines of the space shuttle launch vehicle, which used liquid hydrogen and liquid oxygen (pictured below).

Not exact matches

The first stage used Rocket Propellant - 1, a form of kerosene similar to jet fuel, while the second and third stages relied on liquid hydrogen for fuel.

It can run for up to eight minutes on 1 - milliliter of hydrogen peroxide, the same liquid used around the house to clean and disinfect.

The use of liquid hydrogen and liquid oxygen as propellant is an integral part of the entire Mars Base Camp (MBC) architecture, the company representatives said.

The reaction occurs in a liquid phase and proceeds at relatively low temperatures (about 200 degrees Celsius), unlike the costly current methods of extracting hydrogen from glucose that use pressurized steam.

Over the years, Easley produced code that went on to be used in renewable energy research, including batteries for early hybrid vehicles, as well as for the high - thrust liquid oxygen / liquid hydrogen Centaur rocket used to get space capsules into orbit.

The liquid hydrogen / oxygen (LH2 / LOX) fuel can be used to fill the tanks of manned vehicles travelling between Earth and Mars.

Co-author Professor Sir John Meurig Thomas, from the Department of Materials Science and Metallurgy at the University of Cambridge, said the work could be extended so that many of the liquid components of refined petroleum and inexpensive solid catalysts can pave the way for the generation of massive quantities of high - purity hydrogen for other commercial uses, including CO2 - free energy production.

Bond conceived the idea of using the ultracold liquid hydrogen fuel as a heat sink to take the excess heat out of the incoming air and use some of the hot air to support fuel combustion.

For instance, carbon dioxide enables energy storage by reacting with hydrogen gas — called the hydrogenation process — transforming the mixture into higher energy liquid compounds such as methanol that can be easily transported and used as fuel for cars.

Understanding these effects is also important for other applications such as splitting water molecules to produce hydrogen at solid - liquid interfaces, electronic devices that rely on oxide - oxide interfaces, or other electrochemical processes using these materials as catalysts, where defects serve as the sites that enable the interactions.

Huang refers to the splitting of water, a process used to create gaseous hydrogen and oxygen from liquid water where properly defective molybdenum sulfide could enhance the process and reduce the amounts of energy and costs needed and increase the amount of hydrogen produced.

In addition, the use of hydrogen in an FT plant could nearly triple yields of liquid fuels.

Airplanes, ships and long - distance trains can't be plugged into an outlet, but hydrogen energy could be used to produce liquid fossil fuels, Lewis said.

And catalysts both speed reactions in water and use the liquid as a feedstock to create renewable energy sources such as hydrogen.

The Fischer - Tropsch process is a chemical reaction that uses catalysts to convert two gases, carbon monoxide and hydrogen, to liquid fuels in a simple, one - step process.

Heterogeneous catalysis for controlling gaseous emissions from automotive and stationary engines, alternative energy using catalytic reforming of gaseous and liquid fuels to hydrogen for fuel cells, catalytic processes for upgrading carbon dioxide to useful products

Monounsaturated and polyunsaturated fats are considered as better than saturated fats, and saturated fats are better than artificial trans fats which are created in an industrial process that adds hydrogen to liquid vegetable oils to increase their shelf life and make them solid, easy to use and inexpensive to produce.

Since these oils are liquid at room temperature (unlike traditional baking fats, such as butter and lard), manufacturers figured out a way to use hydrogen atoms to rearrange the chemical structure, turning the product from a liquid to a solid.

Trans fats are artificially created through a process called hydrogenation, which uses hydrogen, pressure and heat to change the chemical structure of vegetable oils from liquid to semi-solid.

It will use gaseous hydrogen (as opposed to liquid) to create electricity and propel the Clarity for about 300 miles.

H2O and CO2 can supply the feedstock for all the liquid fuels currently used for transportation, which are just various molecular recombinations of hydrogen and carbon.

Why bother adding energy to a combustible liquid (gasoline) to remove hydrogen — a gas — that would be harder to use anyway?

Clearly, a liquid is easiest to use, but gaseous hydrogen could be made to suffice.

Instead, it will be used on - location to create gas (methane) or liquid fuel from ambient CO2 and hydrogen from electrolysis.

These can be harvested and used in fuel cells to generate electricity, but now, with the help of an engineered bacteria, the hydrogen can be used to produce liquid fuels.

As Koval points out, even though use of hydrogen in fuel cells is growing, the biggest need is for liquid fuel to run cars, trucks, trains and planes.

And what about the liquid hydrogen fuel used to power the Space Shuttle?

Onboard, self - powered, hydrogen on demand from liquid fuel is way more practical than using conventional land - based electrolysis to supply ultra high pressure tanks with the bulky gas.

The use of nuclear energy to produce liquid fuels is very economic at this point of time, and whilst the production of hydrogen from nuclear electricity is expensive the cost can be reduced by using high temperature steam from nuclear reactors for high temperature electrolysis.
