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.

This article is about how hydrogen from fryers can be used to power stuff. At the beginning it was a long and not enviromentaly friendly; Dr Dupont and colleagues have made a two-stage process that is bettter. the new process is more effient and more eco-freindly. Dr Dupont hopes that we will have a more hydrogen based feul economy. so far the technology works but it will undergo more testing.
Hydrogen is a great green energy source. However it’s very hard to produce, scientists have found a inexpensive way to produce Hydrogen out of vegetable oil. This green hydrogen could be used to power cars or power plants. The hydrogen is produced by heating the vegetable oil and mixing it with steam, then they add sorbent material to trap carbon dioxide. This process have proved to work very well.

Fat grease might just be the new alternative fuel. Hydrogen has proven to be an alternative fuel but there are still problems. Scientist are trying to find ways in which it would not take vast amounts of the liquid. Another problem is the after product or what is left behind. After burning this liquid, it releases large amounts of green house gasses.
Dirty fat from the fryer could be used to make the fuel of the future.

Do not pour dirty fat down the drain it could be used for fuel. Doing this can be a alteritive to fossile fuels. This could one day could power our cars and power plants. This is suitable for gas stations,and also cut off energy lost during transmission or down power lines . Today they are trying everthing to get fuel even us vegtable oil to get fuel
Researchers have figured out a way to make hydrogen out of old vegetable oil thrown out by resteraunts. Hydrogen can be created very easily by simple fossil fuels. The fuel is mixed with steam with a metal catalyst then heated to about 800 or so degrees and forms hydrogen and carbon dioxide. A two step process has been created where its self heating. Researchers have also added a what is called a sorbent to trapall the carbon dioxide produced leaving the hydrogen gas behind.
Scientists have found a way to make hydrogen gas out of used vegetable oils that have been thrown out from restaurants, takeout etc. This process also helps with saving energy and produces some of the energy to make the hydrogen itself. We could eventually start to use hydrogen to run cars, machines and everyday house appliances. They have perfected a two stage process. First they blast the nickel catalyst with air to form nickel oxide (exothermic process) and then the fuel and steam mixture then reacts with the hot nickel to make hydrogen and carbon dioxide.
This article is saying that we can use the oil from food to make simple fuels because hydrogen is a simple and quick fuel.
Using fat from cooking things can be used as fuel in a hydrogen powered vehicle. Some scientists even prefer it over other fuels. Although it the oil doesnt produce as much hydrogen, it is much cheaper. So using vegetable oil for fuel in a hydrogen powered vehicle is much more eco friendly.
Hydrogen is now a cleaner, greener alternative to fossil fuels. Researchers at the University of Leeds have found a way to make hydrogen out of used vegetable oils from restaurants. Hydrogen can already be made pretty easily from simple fossil fuels. Fuel is mixed with steam then heated to above 800 degreesto form hydrogen and carbon dioxide. However the process to turn vegetable oil into hydrogen is not just expensive but not environmentally friendly.
Researchers say that the old vegetable oil can be used for fuel in the near future. There is a 2 stage process in turning the vegetable oil into fuel. The beginning of it is to blast the nickle catalyst with air to form nickle oxide. Then the fuel and steam mix reacts with the fire hot nickle oxide to form hydrogen and carbon dioxide.
Researchers have now found an energy-efficient way to make hydrogen out of used vegetable oils. Hydrogen can already be made easily from simple fossil fuels,and natural gas. The researchers added a special material to trap all the carbon dioxide produced, leaving them with pure hydrogen gas. So as you can see this is a better way.
Left over grease doesnt need to be wasted. It can be used to fuel some cars. It is cleaner and better for the oconomy than fossil fuels. The University of Leeds lerned how to make hydrogen out of leftover fat. It is a 2 step self heating process.

Researchers at the University of Leeds have now found an energy-efficient way to make hydrogen out of used vegetable oils discarded by restaurants or other places. Hydrogen can be made very easily from simple fossil fluids, but when more complex fluids are used it is hard to make much hydrogen without the temperature increasing further. Dr Dupont and colleagues have discoevered a two-stage process that is self-heating. The nickel catalyst is blasted with air to form nickel oxide then fuel and steam mixture reacts with the hot nickel oxide to make hydrogen and carbon dioxide. They have tested their theory and it works efficiently.
This article was about possibly finding a new type of fuel to power things, hydrogen from used vegetable oils. It could be used to power many things such as cars, powerplants, and other things we use in our everyday lifes. A downfall would be in order make more hydrogen, the temperature would have to be raised by a lot when the things are heated, also the left over dirty oil could be unsafe to the environment. But they are finding new ways to get the types of gas they need for it to work.
The researchers at the University of Leeds figured out how to use fat to make hydrogen. So it will be able to be used as fuel. Energy to run such as buildings refigeraters and many more things. I think this will be a good thing that has happened. I think it will affect the world majorly.
This article was about how the University of Leeds as found a new way to make hydrogen out of old or throw away oil that is comminly used in kitchen and resturants. The process is also very enviroment friendly and also very inexpensive. The new fuel can even be used in cars sometime in the future.
in this article it talks about not pouring grease downs the sink because one day it could be used to make fuel in the future. this article also talks about how hydrogen is tipped as a cleaner and greener alternative fuels. also in this article they talk aboutadded a special ’sorbent’ material to trap all the carbon dioxide produced, leaving them with pure hydrogen gas.

It can also be used to power things that would need electricity. It is very expensive to do this process and it is a green house gas but i think that it is a good thing that they have done this because it is friendly to the enviorment and they said that it could cut the amount of power lost in downed power lines.
You shouldnt put dirty fat from the frier down the sink it could be used as gas. Researchers from Leeds University have found an energy-efficient way to make hydrogen out of used vegetable oils. Itll generate energy to make hydrogen but also is essentially carbon-nuetral. Dr Dupont and colleagues have perfected a two-stage which is one where the nickel catalyst is blasted with air to form nickel oxide and an exothermic process. Two is then the fuel and steam mix then it reacts with the hot nickel oxide to make hydrogen and carbon dioxide.
This article is about not wasting fat from frying fuels hydrogen economy. We could stop wasting cause itbe used to get fuel in the future. This can actually help with even drive larger scale power plants. So just do a little thing can make all the diffrence.
Did you know that it’s possible to make oils from fried foods into gas for vehicles? Well it is! This could save earth from using all the natural gases up. To make the oil work, you must heat it up 800 degrees. Scientist have added sorbents, to make sure the oil is pure. This project could change the world.
about wasting fat from frying fuels hydrogen economy. we can stop this because it can and probably will be used as a fuel source in the near futer.this can help with the even drive larger scale power plants
This article is all about going green; using the leftover grease from the fryers, and turning it into what could be the next energy source for power plants and fuels. It is a two step process that creates hydrogen, which will help us create that eco-freindly world we’ve all been hoping for. this is an greenhouse gas, and it could help us save some of the natural gasses this planet has. I think this is a great way to go green and lead the world to a better future.
This article tells us about how scientist are trying to find ways to make fossil fuels with out using vast amounts of energy. and tryong to find new things to make fossil fuels out of.
Basically 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”.
The researchers at the University of Leeds figured out how to use fat to make hydrogen. They have struggled for years to find an efficient way to do this. Hydrogen can be made from fossil fuels heated up in metal catalysts. Using vegetable oil, the catalysts would become poisoned. They want to try larger scales of this two step process.
This article is about the ability to make hydrogen out of dirty vegetable oil from retraunts, takeaways, and pubs. this extraordinary green alternative to fuel can help reduce our impact on our environment by reducing such high ammounts of natural materials we use every day. scientists have yet to find a way to produce this without using vast amounts of energy or spew green house gas, but the ammounts of energy we coul dsave coudl be enormous. Hydrogen is already made very easily from simple fossile fuels wehn they mix the fuel with steam and heat the mixture with a metal catalyst to 800 degres centigrade. “The beauty of this system is that it can operate at any scale being a small power plant or a large filling station” Dr Dupont. This method of providing green energy can hugely help our environment and our homes

Hydrogen has now been found to be a cleaner alternative to fossil fuels. Researches have now discovered a energy-efficient way to make hydrogen out of used vegetable oils that are commonly discarded by restaurants. In the previous process, fuel is mixed with steam then heated to above 800 degrees to form hydrogen and carbon dioxide. Though the new method using vegetable oil is energy-efficient, it is also expensive and not environmentally friendly.
Researchers at the University of Leeds had found that you can make fuel out of cooking oils that are wasted daily by cooking, whether it is cooking done by professional chefs or mere amateurs who just got hungry. The hydrogen fuel from recycled cooking oils can be used to run our cars, power plants, light our buildings, run kettles and fridges, and power computers. Dr. Dupont has perfected a process that is self-heating. Nickel catalysts are blasted with air to form nickel oxide, producing steam. The mixture of the steam and fuel reacts with hot nickel oxide to make hydrogen and carbon dioxide. Hydrogen-powered fuel may be used in the future, for it is ‘green’ and does not waste any irreplaceable fossil fuels.

Since fossile fuels are running low scietist are trying new ways of make gas like using fatty grease to fuel cars but it also puts up alot of green house gasses and there are still problems with it
Hydrogen can be used as a fuel for motors and cars. It is a clean alternative to carbon. But it is hard to find ways to burn the hydrogen without using tons of energy. It also is not a natural alternative, it has to be made by man and can’t be found naturally. Scientists have found a way to do this, and can be done fairly easily. It is an easy two-step process. I think in the future we will be using hydrogen for fuel.
1. fat from frying could be use d to make future gas.
2. Hydrogen -based fuel could possibly be used to run cars light buildings and power computers.
3. hydrogen can be made off of fossil fules, like natural gas.
4. When ur using wasted vegetable oil, it is harder to make hydrogen without raising the temperature higher than 800 degrees.
5. If we could create more electricity using hydrogen-powered fuel cells, that would cut the amount of energy lost during down power lines.
I think this is a good idea cause its better for the enviroment. And it will save alot of energy.
this arcticle told me about not puting deepn fried greece down the kitchen sink.hydrogen is now cleaner and greeener than other fossil fuwls.
It is a two step process that creates hydrogen, which will help us create that eco-freindly world we’ve all been hoping for. if we hgAV A GREENER AND MORE ECONAMICAL gas erecource it will be much easier on me rhan other people .The process is not only expensive but also environmentally awsome.
