I frequently get asked about how much HHO will yield the best mileage gains for a particular car or truck. Years ago, we used the following formula: 1/4 liter per minute for each liter of engine size. For example, if you have a 2 liter engine, you need.5 LPM of HHO.

The amount of hydrogen required is determined by the size of the engine. 0.15 Litres/minute per 1L of engine size is ideal.

How much fuel is in a hydrogen fuel cell vehicle?

A hydrogen fuel-cell vehicle's tank is sized in kilograms. A 4-kilogram hydrogen tank (8.8 pounds) holds the energy equivalent of 4 gallons of gasoline. Today's hydrogen fuel stations can fill such a tank in 3-5 minutes. 3. Is Hydrogen Fuel Safe? The short answer is that hydrogen behaves differently from gasoline.

How much does it cost to make 1 kg of hydrogen?

$1.8015 = $1.80/kg (gge) using Compressed Electrolyses.NOTE: It takes 3 gallons of water to make 1 kg of hydrogen, 1 gallon of water = 0.38 kg of hydrogen, roughly a 3:1 ratio. Therefore: 1000 gallons of water ÷ 3 = (produces) 333 kg of H2

What do you need to know about hydrogen-powered cars?

Ford, Nissan and Volkswagen also are developing electric-drive cars fueled by hydrogen gas. Here's what you need to know about these cars and the safety of this unfamiliar fuel. The vehicles don't need gasoline. They aren't tied to an electric plug. They produce zero emissions from the tailpipe and can deliver 300 miles or more per tank of fuel.

Can hydrogen be used as a fuel for engines?

Fenske has been exploring hydrogen's possibilities in multiple videos already this month, both as a fuel for piston engines and rotary engines. There are two major problems with a hydrogen internal combustion engine.

How far can a car drive on 1 kg of hydrogen?

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

Can a normal car engine run on hydrogen?

Both hydrogen internal combustion engines and hydrogen fuel cells can power vehicles using hydrogen, a zero-carbon fuel. Hydrogen engines burn hydrogen in an internal combustion engine, in just the same way gasoline is used in an engine.

How much hydrogen does a hydrogen car need?

An FCEV can drive about 28 miles (45 km) on 1 lb (0.45 kg) of hydrogen. The cost per mile of running hydrogen cars is therefore currently almost twice as high as that of battery-powered vehicles charged at home.

How far can a car go on 1 gallon of hydrogen?

Fueling and Driving Range Some FCVs can get over 300 miles on one tank of hydrogen fuel — greater than the distance from St. Louis to Chicago — and fuel economy close to 70 MPGe (miles per gasoline gallon equivalent).

Why don't we use hydrogen as a fuel?

So, even though H is good fuel, we cannot economically burn it in small environments like cars or hosehold, So, we donot depend primarly on H as fuel.

Is hydrogen fuel expensive?

Currently, renewable hydrogen produced via electrolysis costs between US$3 – US$6/kg, though analysts expect this figure to drop significantly over the next decade.

Is hydrogen fuel cheaper than gasoline?

In 2021, hydrogen retailed $8.50/kg to $10.80/kg higher than gasoline prices matching the same fuel cost per mile for hybrids or conventional gasoline vehicles respectively. Hydrogen has been used commercially for over 80 years, so it is well developed.

What is the cost of 1 Litre of hydrogen?

The cost of hydrogen as fuel is very cheap when compare to other fuels. Hydrogen gas costs just Rs. 30 per liter making it the cheapest option that India is not considering.

Will hydrogen cars overtake electric?

A new study published in the peer-reviewed journal Nature has confirmed what common sense has made clear for years: Hydrogen fuel cell vehicles aren't likely to catch up to battery-electric vehicles – even for commercial trucks. The auto industry has been divided on solutions to remove emissions from their products.

Why hydrogen is not the future?

Sure, hydrogen is the most abundant element in the universe, and it's only used as an energy carrier, so it doesn't get used up in a fuel cell. However, it doesn't exactly grow on trees either, and there are no underground “hydrogen pockets” that we can simply pump it out from.

Are hydrogen cars better than electric?

As with electric cars, hydrogen cars produce zero harmful emissions on the road, but unlike electric cars, which take a fair amount of time to recharge, hydrogen cars can be refilled about as quickly as a petrol or diesel car.

How much does a gallon of hydrogen fuel cost?

Hydrogen fuel is much more efficient than gasoline, but it's also four times more expensive, roughly equivalent to about $16 a gallon.

Can you modify a car to run on hydrogen?

It is also true that to convert an automobile from gasoline or diesel to hydrogen, the engine, the complete fuel supply, and distribution system, the transmission, and the gearbox must all be replaced. To put it another way, the overall cost of the surgery will be larger than the vehicle itself.

Is hydrogen better than electric for cars?

Hydrogen-fueled cars have some advantages over EVs. They can run for 300 miles, and fueling up takes 10 minutes. EVs can go about 200 miles, and juicing up can take 45 minutes. EVs lose range in cold weather.

Can a piston engine run on hydrogen?

As Jason Fenske of Engineering Explained lays out, you could design a piston engine to run on hydrogen. It just wouldn't be very good. Hydrogen is a tempting alternative fuel. When burned correctly, its only emission is water vapor.

Is hydrogen better than gasoline?

Emissions from gasoline and diesel vehicles—such as nitrogen oxides, hydrocarbons, and particulate matter—are a major source of this pollution. Hydrogen-powered fuel cell electric vehicles emit none of these harmful substances—only water (H2O) and warm air.

Why are hydrogen fuels being used in cars?

The only reason hydrogen-fueled vehicles are being pursued by auto manufacturers is that they are under pressure to increase their average fuel economy. The carbon pollution typical of hydrogen fuel manufacture does not count against the corporate average fuel economy standards (CAFE standards) mandated in the US, so auto manufacturers can just fob that CO2 cost onto society while claiming nonexistent environmental credibility.

How to generate hydrogen fuel?

One possible route to generating hydrogen fuel that doesn't take from Peter to pay Paul is to pair hydrogen generation with a very-high-temperature nuclear power plant (VHTR) that operates at a sufficient temperature (about 900° C) to separate water into hydrogen and oxygen thermally rather than electrically. In this case, hydrogen generation can be considered a byproduct of cooling the reactor. It's practically free, once you've invested the $20 billion into building the plant.

How much H2 does a Honda accord have?

Another comparison would be the Honda Clarity FCX and the Accord. The FCX Clarity gets a combined highway/city of 72 miles/kg of H2. The similarly sized Accord-LX gets a combined of 29 miles/gal (0.40 kg H2 / gal). Replacing the 17.2 gallon tank of the accord would take 6.9 kg of H2. They have actually only installed 4.1 kg of H2 storage on the FCX Clarity.

How to get more hydrogen storage?

Getting more Hydrogen storage in could be done but you would have to sacrifice more of the vehicle to it. Either make the tanks bigger/more tanks or increase the pressure.

Why not use electrolysis to split water into oxygen and hydrogen using solar photovoltaics?

Why not just use electrolysis to split water into oxygen and hydrogen using solar photovoltaics? Because that is an inefficient way to use solar power. Under the best conditions, only 10 percent or less of the incoming solar radiation gets stored in the hydrogen gas, and that's at atmospheric pressure. It takes further energy to compress the gas so that it is contained in a small enough volume to fit in a vehicle. Efficency-wise, unless we have more solar power than we know what to do with, we'd be much better off using the electricity to charge batteries and use the batteries to propel the vehicle.

What are the problems with hydrogen?

They were but there are at least three major problems with them: 1 Their source of hydrogen comes from industrial sources that can only make it cheaply enough using the “steam reformation” process which uses fossil fuels as the feed-stock. That makes it MORE damaging to the environment than fossil fuelled vehicles. 2 Hydrogen is difficult and dangerous to transport and is virtually impossible to send down pipelines because of hydrogen embrittlement of most metals. So it has to be carried by truck - and that’s very bad news. New hydrogen filling stations have to undergo a mountain of safety and envir

How much H2 is needed to replace a gallon of gas?

A rough rule of thumb is 0.4 kg of H2 is needed to replace a gallon of gasoline.

How much hydrogen is needed to make fuel cells?

To make it into fuel for fuel-cell vehicles, the hydrogen must be compressed. The present standard is 10,000 pounds per square inch, which also is designated as 700 bars. It is then chilled to keep it from heating and expanding as it is pumped into the vehicle. That equipment is part of the fueling station.

How many gallons of gasoline does a hydrogen tank hold?

A hydrogen fuel-cell vehicle's tank is sized in kilograms. A 4-kilogram hydrogen tank (8.8 pounds) holds the energy equivalent of 4 gallons of gasoline. Today's hydrogen fuel stations can fill such a tank in 3-5 minutes. 3.

How do electrons return to the fuel cell?

After their job is done, the electrons return to the fuel cell, where they are reunited with the parent hydrogen in the presence of oxygen pulled in from the ambient air. They meet in a ratio of two atoms of hydrogen to one of oxygen. Presto! It's H2O, or water.

What is fuel cell?

The fuel cell is the system's power plant. In it, hydrogen gas drawn from an onboard pressurized tank reacts with a catalyst, typically made of platinum. The process strips the electrons from the hydrogen, freeing them to do their thing — which is to be the electricity that flows through the electric motor to power the car.

How do fuel cells work?

One fuel cell doesn't produce all that many electrons, so automakers bind scores of the flat, rectangular cells together into a fuel-cell stack to get enough juice to power a car or truck. The stack acts much like a battery, releasing electricity in a constant flow to power the vehicle's electric motor and auxiliary electronics.

What cars use hydrogen gas?

Ford, Nissan and Volkswagen also are developing electric-drive cars fueled by hydrogen gas. Here's what you need to know about these cars and the safety of this unfamiliar fuel. The vehicles don't need gasoline. They aren't tied to an electric plug.

What is a hydrogen fuel cell?

"Hydrogen fuel-cell vehicle" sounds pretty exotic, but in reality it's just an electric car that replaces the bulky, heavy and expensive grid-charged battery pack with a relatively small, lightweight and expensive electrochemical system that produces electricity onboard.

How does hydrogen fuel work?

Hydrogen enhances combustion of the existing fuel which results in significant economy gains due to the fact that hydrogen-fuel mixtures burns more completely. However, the challenges to produce enough hydrogen to run an engine without gasoline include: an excessively large and expensive HHO generating system.

How much power is needed to produce 148 KW of HHO?

Consumer grade electrolysers are about 50% efficient, thus 296 KW of electrical power is required to produce the necessary 148 KW of HHO. This power is taken from the battery of the car.

What would fill a trailer that must be towed by the car?

the HHO generator, water reservoir and battery bank would fill a trailer that must be towed by the car

How dynamic are vehicle engines?

Vehicle engines are very dynamic in their fuelling requirements and change dramatically within fractions of a second.

Is a 296 KW battery more efficient than a gasoline battery?

In conclusion, if a 296 KW battery source is available, it would be much more efficient to use it in an electric vehicle and avoid all the energy losses of the gasoline engine and the electrolyser.

How much HHO should I use for mileage?

I frequently get asked about how much HHO will yield the best mileage gains for a particular car or truck. Years ago, we used the following formula: 1/4 liter per minute for each liter of engine size. For example, if you have a 2 liter engine, you need .5 LPM of HHO. In practice this is a pretty good formula to use, because most people measure HHO using ball meters or pop bottle test. These tests are not particularly accurate, and tend to read higher flow rates than actual. So with this in mind, the formula will work pretty well.

How many amps does a 15 liter semi truck use?

For 15 liter semi trucks, we use 1.25 - 1.5 LPM, and we run at about 25 amps to get it.

Is HHO production directly proportional to amps?

Since good accurate measurement of HHO flow is not available to the average user, we have provided an alternate way to work with this data. All things being equal, the HHO production is directly proportional to the amps.

Does HHO give back energy?

HHO, when burned, does not give back as much energy as the energy that was used to create it. There are several energy conversions involved. Since there is no such thing as 100% efficiency, energy is lost at each conversion. The conversions are: mechanical to electrical (alternator), electrical to chemical (electrolyser), ...

Does HHO increase mileage?

There can be some variance in cell efficiency. But you will find that the correct amount of HHO will give you the best gain in MPG, and that more HHO will start to reduce that mileage. Add more and more HHO, and you can end up with lower mileage than when you started. We'll explain why further on in this article.

How much energy does it take to make hydrogen?

Meanwhile, making clean hydrogen is energy intensive and you throw away a lot of the energy. Let’s assume they get 10 MWh of electricity from a wind farm. Then they convert water to hydrogen and oxygen with the electricity. High-efficiency PEM electrolysis is about 80% efficient (projected to rise to a theoretical peak of 86%). That takes about 50 kWh per kilogram, so you have a couple of hundred kilograms of hydrogen.

How much hydrogen is equivalent to a gallon of gas?

Well, a kilogram of hydrogen is the energy equivalent of a gallon of gas. Hydrogen fuel cells are about three times as efficient at converting hydrogen to energy as internal combustion engines are at turning gasoline into energy, so you go about three times as far on a kilogram of hydrogen despite it having the same energy.

How many miles can a Toyota Mirai drive?

Those 200 kg will allow a Toyota Mirai to drive about about 13,000 miles. Let’s be nice and say the retail price of hydrogen gets down to $10 per kg. That will cost you $2,000 to drive those 13,000 miles.

How much transportation play does the slipperiest molecule have?

The slipperiest molecule might have a 3-4% transportation play in larger form factors (and maybe it will hold onto its forklift market for a while longer), but for cars it makes no sense. By. Michael Barnard. Published.

How much electricity is left in hydrogen?

You’ve thrown away 20% of the electricity and are left with 8 MWh embodied in the hydrogen.

Is hydrogen a dumb idea?

There’s no way to square that circle. There are other reasons, but this is the reality of hydrogen for cars. It’s a dumb idea economically for individuals and it’s a dumb idea for the environment too. It’s much, much better to decarbonize the grid and put that electricity into cars than into hydrogen. The slipperiest molecule might have ...

Do hydrogen stations exist?

And those hydrogen stations don’t exist. They all have to be built on somebody’s nickel.

Why use hydrogen in a fuel cell?

Use hydrogen in a fuel cell to generate electricity. Fuel cells are far more efficient than internal combustion engines, and a hydrogen fuel cell has cleaner emissions than an internal-combustion hydrogen engine. To learn more, check out Fenske's full video below. This content is imported from YouTube. You may be able to find the same content in ...

What happens when you combust hydrogen?

When you combust hydrogen, you get other emissions besides water vapor. Mainly, you get NOx, the toxic emission at the heart of the Volkswagen diesel emissions cheating scandal. If you're looking for a clean alternative to gasoline, hydrogen's NOx emissions take it out of the running.

Can a piston engine run on hydrogen?

As Jason Fenske of Engineering Explained lays out, you could design a piston engine to run on hydrogen. It just wouldn't be very good . Hydrogen is a tempting alternative fuel. When burned correctly, its only emission is water vapor.
