Don’t pour that dirty fat from the fryer down the sink — it could be used to make the fuel of the future.
Hydrogen has been tipped as a cleaner, greener alternative to fossil fuels. But scientists have struggled to find a way to make it that doesn’t consume vast amounts of energy, use up scarce natural resources, or spew out high levels of greenhouse gas.
Researchers at the University of Leeds have now found an energy-efficient way to make hydrogen out of used vegetable oils discarded by restaurants, takeaways and pubs. Not only does the process generate some of the energy needed to make the hydrogen gas itself, it is also essentially carbon-neutral.
“We are working towards a vision of the hydrogen economy,” said Dr Valerie Dupont, who is leading the Leeds-based project. “Hydrogen -based fuel could potentially be used to run our cars or even drive larger scale power plants, generating the electricity we need to light our buildings, run our kettles and fridges, and power our computers. But hydrogen does not occur naturally, it has to be made. With this process, we can do that in a sustainable way by recycling waste materials, such as used cooking oil.”
Hydrogen can already be made quite easily from simple fossil fuels, such as natural gas. The fuel is mixed with steam in the presence of a metal catalyst then heated to above 800 degrees centigrade to form hydrogen and carbon dioxide.
However when much more complex fuels are used, such as waste vegetable oil, it is difficult to make very much hydrogen using this method without raising the temperature even further. The reactions could be run at lower temperatures but the catalysts would quickly become poisoned by residues left over from the dirty oil. In short, the process is not only expensive but also environmentally unsound.
Dr Dupont and colleagues have perfected a two-stage process that is essentially self-heating. To begin, the nickel catalyst is blasted with air to form nickel oxide — an ‘exothermic’ process that can raise the starting temperature of 650 degrees by another 200 degrees. The fuel and steam mixture then reacts with the hot nickel oxide to make hydrogen and carbon dioxide.
The researchers also added a special ’sorbent’ material to trap all the carbon dioxide produced, leaving them with pure hydrogen gas. This trick eliminated the greenhouse gas emissions and also forced the reaction to keep running, increasing the amount of hydrogen made.
“The hydrogen starts to be made almost straight away, you don’t have to wait for all of the catalyst to be turned into pure nickel,” Dr Dupont said. “So as well as the generation of heat, this is another way that makes the process very efficient.”
The researchers have shown that the two-stage process works well in a small, test reactor. They now want to scale-up the trials and make larger volumes of hydrogen gas over longer periods of time.
“The beauty of this technology is that it can be operated at any scale. It is just as suitable for use at a filling station as at a small power plant,” Dr Dupont said. “If we could create more of our electricity locally using hydrogen-powered fuel cells, then we could cut the amount of energy lost during transmission down power lines.”
Details of the work will be published in the journal Bioresource Technology.
The project was funded by the Engineering and Physical Sciences Research Council (EPSRC) and benefited from industrial collaboration with Johnson Matthey.

They are working towards a vision of the hydrogen economy. who is leading the Leeds based project. Hydrogen based fuel could potentially be used to run our cars or even drive larger scale power plants, generating the electricity we need to light our buildings, run our kettles and fridges, and power our computers. But hydrogen does not occur naturally it has to be made. With this process we can do that in a sustainable way by recycling waste materials such as used cooking oil.
This article is about recycling. The vegetable oil discarded by resurants can be recycled and reused. These oils can be used to make hydrogen gas itself. The oils are also carbon neutral. I think this is a great way to stay “green”.
I learned not tp put deepn fried greece down the kitchen sink. Hydrogen is now cleaner and greeener than other fossil fuels. This process is not expensice and if we all can learn to pitch in and help it would be a great way to help our enviroment.
Fat from a fryer can be used to make fuel for the future. Scientist have now found an energy efficient way to make hydrogen out of used vegetable oils discarded by restaurants. Fat from cooking can be used as fuel in a hydrogen powered vehicle. Scientist say the more fat from fryer used the less resources being wasted.
Its a waste these days to pour deep fried grease into the sink. You can nowadays use the hydrogen from the grease to make fossil fuels that can possibly power cars. Scientists from the University of Leeds have discovered that vegetable oils produce hydrogen that is entirely carbon-neutral. When fuel is mixed with steam in a metal catalyst and then heated to above 800 degrees it forms hydrogen and also carbon dioxide. Dr Valerie Dupont states “We are working towards a vision of the hydrogen economy”. This is the future.
*This article belongs to the process of recycling,that how we can use the wasted vegetable or cooking oil in the formation of hydrogen gas.
*It is difficult to made hydrogen by usig leftover oil without raising the temperature because catalyst become poisoned by residues in dirty oil.This is expensive and environment also become dirty.
*Hydrogen can also be made easily from fossil fuels, such as natural gas. The fuel is mixed with steam in the presence of a metal catalyst and heated at above 800 degrees centigrade to form hydrogen and carbon dioxide.
*Hydrogen based fuel will be helpful to us in running cars,generating electricity and in larger scale power plants.

1. Hydrogen can be made out of vegetable oil in ways that are carbon neutral and wont spill out large amounts of greenhouse gases that could effect the environment.
2. Hydrogen based fuels could be the future therefore, they would be able to power our cars, our computers, all by generating electricity.
3. However, when making hydrogen gas out of substances such as vegetable oil the process is not only very expensive but it is also hazardous to the environment.
4. there is a two step process to making this hydrogen and carbon dioxide: the nickel catalyst is shot with air to form nickel oxide at which point an exothermic process then raises the starting temperature. The fuel and steam combination then reacts with the nickel oxide.
5. creating electricity by locally using hydrogen powered fuel cells, it would then allow us to be able to cut out the amount of electricity loss.
The use of hydrogen is an efficient way to recycle and keep from using all of the unexploited natural resources still on earth. Scientists have found a method and are still improving upon it to turn vegetable oil, from deep fryers, into hydrogen, which can fuel a car. Using hydrogen is a much cleaner fuel that is a great alternative to the fossil fuels that we still use enormous amounts of today. The hydrogen produced from the vegetable oil is more complex to make rather than from natural gas, but natural gas emits many more greenhouse gases into the aptmosphere.
1. Used vegetable oil is carbon neutral.
2. Scientists are working towards a hydrogen based economy.
3. Hydrogen is made, it does not occur naturally.
4. Hydrogen is formed by mixing fossil fuel and steam in with a metal catalyst and heating it to above 800 degrees.
5. Hydrogen is cleaner than other fossil fuels.
Although hydrogen was known to be a valuable fuel source, scientists couldn’t find a way to safely and efficiently produce hydrogen to be used as fuel. However, scientists at the University of Leeds have found a safe, two-step process to super-heat the grease from deep friers to produce hydrogen and carbon dioxide. Although small scale, hopefully large scale hydrogen plants will be implemented so as to reduce the amount of wasted electricity.
1) Frying grease and vegetable oil is a method used to create hydrogen gas.
2) Scientists have discovered that harnessing hydrogen to create energy could be an effective way to decrease use of fossil fuels.
3) Effectively harnessing hydrogen power is difficult and requires high temperatures.
4) Experimentation with a safe and cheap way to harness this energy has been done, and scientists use nickel catalyst and sorbent. This acts as a process used to heat from the outside, reducing the amount of energy it takes to access the hydrogen in the substance.
5) Using vegetable oils to create energy can be done at any location. This would eliminate the cost of transferring and transporting energy.
This article states the reuse of fats from frying foods in resturants. It also state that hydrgen cannot occur naturally therefore in this method you can make it by recycling waste materials like used cooking oil. “The beauty of this technology is that it can be operated at any scale. It is just as suitable for use at a filling station as at a small power plant,” Dr Dupont said. “If we could create more of our electricity locally using hydrogen-powered fuel cells, then we could cut the amount of energy lost during transmission down power lines.” By recycling your used cooking oil you can help in the process of making hydrgen.
they have found out that you can use grease and fats from the food that they cook like chicken and thinngs like that they can turn into hydrogen out of all the oils. the fats that the hydrogens come from can be mixed with the grease and turned into fossiles. I thought the coolest thing was that they can use fats to to fule into some cars. these are just cool facts that can help us save money and help use less suplies.
Generating hydrogen in an efficient, greenhouse friendly way has been a problem recently but a solution may have been found. A common household material such as cooking oil may be the key to that solution. Cooking oil is a practical source of hydrogen and is very abundant. Hydrogen is needed because it can be an efficient replacement for gasoline which is good for the environment. Researchers at the University of Leeds have discovered that vegetable oil produces hydrogen that is carbon-neutral. This is a first step in progressing towards a “hydrogen economy” as described by Dr. Dupont.

1.Hydrogen has been found to be a cleaner energy source than what we currently use, but because it must be used in vast amounts to equal the energy created by a fuel like gasoline, it hasn’t been widely used.
2.Hydrogen must be made, and the heating up of natural gas to 800 degrees centigrade does this.
3. It has also been found that the leftover oils that had food cooked in them at restaurants also create hydrogen.
4.However, the waste vegetable oils do not create as much hydrogen unless the temperature is pushed even higher than 800 centigrade. Also, the catalysts in the reaction become poisoned by the residue of the dirty oil.
5.Even so, a more efficient process involving nickel oxide has been developed and may be able to work on larger scales to create electricity for entire cities.
They are working on using hydrogen as a natural resource for the future of the economy. Hydrogen can be used to fuel things like cars or to power things to cook with. Scientist believe that in the future hydrgogen will be a resource used by many to to many things.
1. Hydrogen processed from the vegetable oils unused from restuarants can generate energy to make hydrogen gas itself.
2. Hydrogen-based fuels can possibly run our cars and produce electricity in many areas of our life that would generally need gas or other fossil fuels.
3. The downfall to the usual process using waste vegetable oils is expensive as well as environmentally unsound.
4. Scientists have found a more efficient way in producing hydrogen gas, which includes two steps.
5. This new method uses nickle as a catalyst and a sorbent material to trap any greenhouse gases, leaving only pure hydrogen gas.

- The process for making hydrogen produces hydrogen itself and is carbon-neutral
- It has to be made, but that can be done easily
- Hydrogen might one day fuel our cars, provide the electricity to power large power plants and our homes.
- We can even use the leftover vegetable cooking oils that restaurants throw out and recycled items.

2.Also Hydrogen can be used as a cleaner.
3.Natural can make hydrogen.
4. In the the future we might be using hydrogen based gas in our cars.
5. It is very easy to make hydrogen because you use hydrogen to make more hydrogen.
Over the last several years, scientists have been trying to find a way to make hydrogen without using vast amounts of energy and without harming the enviroment, and they think they may have found their answer in used vegatable oils. Although the carbon-footprint left behind by manufacturing hydrogen from vegatable oil is small, it remained a difficult and expensive process due to the oil’s complex chemical formula. However, Dr. Dupont and colleagues believe that they have perfected a two-step process that will make the hydrogen creation process more efficient. This new process, he believes, will allow us to move to cleaner, more enviromentally friendly fuel sources in the future.
The scientist of Leeds university found a way how to make energy-efficient way to make hydrogen out of used vegetable oils thrown away by restaurants, takeaways and pubs. Hydrogen has to be made and it could be used in the future as the fuel for the cars and even it might be able to run the energy plants. The researchers also added a special material to trap all the carbon dioxide produced, leaving them with pure hydrogen gas.This eliminated the greenhouse effect which is bad for the environment and increased the production of Hydrogen. If hydrogen would be used as a a main source of fuel then the energy that is lost during the transmission could be saved.
