In some occasions, you will have to write an essay in the extremely short amount of time on the exam in college or high school. Also, you may be a little bit of a procrastinator, and find yourself in a situation when the paper is due tomorrow morning, and you have not even chosen the topic yet. Even though a last-minute essay cannot look as great as a work prepared successively and carefully within the whole time given, you still have a chance to submit a decent paper. The working process will require your full attention and a lot of effort, even if you are assigned a simple essay. However, if you learn the next few tips, the essay writing will seem significantly easier and feasible even when you are short on time.

Firstly, clean up your working space to get started. Make sure you have everything you need on the table, take a pen, a few sticky notes, your laptop, and read through the assignment requirements. In case no prompt is given, search for good essay topics, and pick a few uncommon and interesting ones you will be able to write about. Making a final choice, think which topic is the most relevant to your current studies and will not take too much to research.

Afterwards, look for the most trustworthy sources or the ones you are certainly allowed to use. If you are not sure, access the online library or any free services where you can look for the books and articles for your essay. Use sticky notes to write down the information and put them in front of you to see how much data has been gathered and if you need to continue researching. Reread these notes from time to time and cross out the info you do not find relevant anymore.

When you have the data you need to produce a quality work, it is crucial to think about the structure of the future paper. If you are not sure how to write an essay outline properly, check what your essay type is first. Each type is organized differently, so you need to look up the structure every time you are given an essay homework. You can also search for an example of the essay on your topic, and adhere to its outline. No matter what kind of essay you are going to write, it is important to start with a thesis statement. It should declare what problem you will review in the paper, and which facts or arguments you will use to do it professionally. As these arguments will be discussed in the main part of the essay, outline the body paragraphs and put down a few sentences with the rough description of each paragraph. Think of the way you will engage the reader in the introduction, and which thought will be conclusive for the paper. When the direction of the work is clear from the outline, use it to draft the first version of the essay.

If you are not used to model essay writing, do not worry - your draft should not necessarily look like a masterpiece. It is only the depiction of your thoughts, and as you will have them written down, it will be easier to create a good essay. There is no best way to write an essay, so trust the working methods you usually use. You may like taking short breaks once in a few minutes, or write everything in one sit - just make sure to keep the focus on writing and avoid the urge to call a friend or watch something online. Thus, you will finish the paper faster, and will not feel guilty for engaging in other activities afterwards.

Do not forget to go through the essay a few times after the completion. Everyone makes typos and mistakes by accident, but it is about you to find and fix them before your teacher does. If you need help with an essay editing, try asking a friend or a family member to read and analyze your work. Also, you can order editing services in case your paper needs to be perfectly polished so that you can submit an ideal essay and get an excellent grade.

As these steps are simple to follow, you will not have any problems coping with an essay on time. Try the whole procedure at least once, and you will not have to use any other tips preparing an essay paper during your studies!

How efficient is a hydrogen electrolyser?

Very roughly, a new electrolysis plant today delivers energy efficiency of around 80%. That is, the energy value of the hydrogen produced is about 80% of the electricity used to split the water molecule. Steam reforming is around 65% efficient.

Is there a hydrogen generator?

A Hydrogen generator is a machine that is used to produce hydrogen from water, using a process called electrolysis. If the supply pressure of hydrogen from the generator is high enough, it can eliminate the need for hydrogen cylinders by providing a safer and more user friendly alternative alternative.

How much does a hydrogen electrolyzer cost?

Hydrogen can be produced from polymer electrolyte membrane (PEM) electrolyzers at a cost of ~$5 to $6/kg-H2, assuming existing technology, low volume electrolyzer capital costs as high as $1,500/kW, and grid electricity prices of $0.05/kWh to $0.07/kWh.

Which gas is used in hydrogen generator?

hydrogen gas
A hydrogen generator uses a proton exchange membrane (PEM) to produce high purity hydrogen gas from water. The PEM cell was originally developed by NASA and is extensively used in industrial and laboratory applications.

How many kWh is 1kg of hydrogen?

33.33 kWh
1 kg of hydrogen contains 33.33 kWh of usable energy, whereas petrol and diesel only hold about 12 kWh/kg (see www.h2data.de).

How many kWh does it take to produce 1 kg of hydrogen?

Producing 1 kg of hydrogen requires about 5 kWh of electricity for process heat.

Does hydrogen generators really work?

It won’t work. (Here ‘work’ means ‘save you money’. It will generate hydrogen and oxygen gasses.) It could easily burn the car down or blow you up.

How efficient is a hydrogen generator?

The current efficiency of the hydrogen generator is 89.13 %. The highest volume of resulted gas from electrolysis process is 0.9250 LPM at the 0.05 M solution concentration in 15 A.

Is hydrogen cheaper than gasoline?

Considerations. While hydrogen is a cheaper fuel than gasoline on paper, the reality is, as of 2010, it is much more expensive. The few models of hydrogen-fueled cars that are commercially available generally cost more than $100,000. Researchers are still tweaking the technology to produce and transport hydrogen fuel.

How far can you drive with 1 kg of hydrogen?

In any of the latest fuel cell cars, 1 kg of hydrogen will let you drive 97 – 100 km.

Why hydrogen gas is used in generator?

Hydrogen cooled power generators are more efficient and have less mass of materials of construction than their air-cooled cousins. Hydrogen gas is 7 times more effective as a heat transfer medium than air and 1/14th the density, resulting in less friction losses and more fuel converted to electricity.

Why is green hydrogen expensive?

High cost: energy from renewable sources, which are key to generating green hydrogen through electrolysis, is more expensive to generate, which in turn makes hydrogen more expensive to obtain.

What is a hydrogen gas generator?

Parker hydrogen gas generators, available in a wide selection of models and configurations, produce a continuous flow of high-purity and ultra-high-purity hydrogen from de-ionized water and electricity. This hydrogen is used in a variety of carrier gas, fuel cell, fuel gas, reaction gas and gas chromatography applications.

What is meant by nascent hydrogen?

The meaning of nascent is newly born. In context of chemical reaction, nascent hydrogen or element means such elements which are produced in situ and are highly reactive elements compared to their ordinary forms. That is nascent hydrogen is more reactive than molecular hydrogen.

Why is nascent hydrogen so reactive?

Nascent hydrogen is very reactive due to which it reacts with chemicals which don’t react with molecular hydrogen in normal condition. There are examples of strong reducing properties of nascent hydrogen which is not shown by ordinary hydrogen, but first let’s discuss why nascent hydrogen is more reactive than molecular hydrogen.

What is the flow rate of a high purity hydrogen generator?

Ultra high purity hydrogen generators providing flow rates up to 1,300 ml/m up to 11.9 bar.
