Difference Between Grey Blue and Green Hydrogen

Difference Between Grey Blue and Green Hydrogen

Blue hydrogen uses carbon capture and storage for the greenhouse gases produced in the creation of grey hydrogen. 2 Green hydrogen production – the ultimate clean hydrogen resource – uses renewable energy to create hydrogen fuel. ... That energy could come from renewables.

What's the difference between green and blue hydrogen?

Blue hydrogen is created from fossil sources, where the carbon emissions are captured and stored. Green hydrogen is made from non-fossil sources and favoured by policy makers who are wary of keeping the fossil economy going, even with CCS.

What is GREY hydrogen?

Grey Hydrogen is hydrogen produced using fossil fuels such as natural gas. Unfortunately this accounts from roughly 95% of the hydrogen produced in the world today.

What is green hydrogen used for?

Hydrogen has many uses. Green hydrogen can be used in industry and can be stored in existing gas pipelines to power household appliances. It can transport renewable energy when converted into a carrier such as ammonia, a zero-carbon fuel for shipping, for example.

What is blue hydrogen?

What is blue hydrogen? Blue hydrogen is when natural gas is split into hydrogen and CO2 either by Steam Methane Reforming (SMR) or Auto Thermal Reforming (ATR), but the CO2 is captured and then stored. As the greenhouse gasses are captured, this mitigates the environmental impacts on the planet.

Is Blue Gas real?

Technically, blue gas is gasoline or diesel that is a hydrocarbon fuel manufactured from hydrogen and carbon feedstocks instead of being refined from petroleum.

Is hydrogen dangerous to humans?

Hydrogen isn't poisonous, but if you should breathe pure hydrogen you could die of asphyxiation simply because you'll be deprived of oxygen. ... Because it's highly compressed, liquid hydrogen is extremely cold. If it should escape from its tank and come in contact with skin it can cause severe frostbite.

What is the Colour of hydrogen?

Hydrogen is a colourless gas – depending on the production type, different colours are assigned to the hydrogen. Green hydrogen is produced by electrolysis of water, using only electricity from renewable energies.

What is the smell of hydrogen?

Hydrogen sulfide is a colorless, flammable gas that smells like rotten eggs at low concentration levels in the air. It is commonly known as sewer gas, stink damp, and manure gas. At high concentration levels, it has a sickening sweet odor.

How much does 1kg of hydrogen cost?

You'll pay £9.99 per kilo of hydrogen, so a 4.7kg fill-up costs about £47. That's 5.74 miles per pound over 270 miles, or 17.4 pence per mile. A 40mpg petrol saloon fuelled at £1.20 per litre/£5.46 per gallon would use 8.1 gallons over that same 270 miles, the total cost of which would be £44.20.

Can I produce hydrogen at home?

It's easy to make hydrogen gas at home or in a lab using common chemicals and everyday materials. Once you have the gas, you can use it for a variety of interesting science projects. Of course, you're not “making” hydrogen, since it's an element. It is produced by chemical reactions that release it.

Is Green Hydrogen Safe?

Green hydrogen is safer than conventional fuels

While no fuel is 100 percent safe, green hydrogen has been shown to be safer than conventional fuels in a multitude of aspects. Hydrogen is not toxic, unlike conventional fuels. ... Hydrogen has a higher oxygen requirement for explosion than fossil fuels.

Is hydrogen expensive to produce?

The cost of hydrogen production is an important issue. Hydrogen produced by steam reformation costs approximately three times the cost of natural gas per unit of energy produced. This means that if natural gas costs $6/million BTU, then hydrogen will be $18/million BTU.
