Green Hydrogen for a sustainable future
Green hydrogen is regarded as the most promising energy source to decarbonise sectors such as heavy transportation, aviation and industrial processes that currently rely on fossil fuels.
How viable is #Green_Hydrogen as a major power alternative?
Is it the key to a lower carbon economy and being more energy self-sufficient?
Listen to Kim Hill’s Radio New Zealand interview - "The rise of green hydrogen" by Christopher Boyle the co-founder and CEO of AFCryo.
It’s time to come clean!
Global demand forecasts for hydrogen are high. New Zealand has the opportunity to become the world’s first large-scale producer of Green Hydrogen.
The future of energy involves renewable energies such as solar, wind and hydro. These are most efficient when plugged into a wall socket, however as you become mobile, the energy efficiency reduces in such things as electric batteries(BEV). They do however have their place.
The future relies on solutions incorporating all of these.
We have a soft spot for hydrogen, and specifically
Green Hydrogen.
Why? Because we care about our environment, and NZ is perfectly situated to embrace a Green Hydrogen future where all of our energy requirements are provided in country.
“Green hydrogen is seen as a game changer for the low-carbon transition. With the right investment, it could supply up to one-quarter of the world’s energy needs by 2050 and eliminate up to one-third of global emissions”
EY (May 2021) Why hydrogen is starting to get the green light in global renewables
What is Hydrogen?
It is the simplest,
lightest and
most abundant element
in the universe, making up more than 90% of all matter.
In its normal gaseous state, hydrogen is odorless, tasteless, colorless and non-toxic. It reacts readily with oxygen, releasing considerable amounts of energy as heat and producing only water as exhaust. It has a high energy content by weight – nearly three times that of gasoline.
Hydrogen is generally encountered as molecular hydrogen (H2). It is an energy carrier that can transfer and store energy: it is not a primary energy source such as natural gas, coal, biomass or wind.

Blue: basically brown, but the CO2 created is then captured, and this must then be permanently stored somehow (a significant disadvantage).
Brown: created by hydrocarbon-rich feedstock, such as fossil fuel, methane, coal. Creates as much CO2 as burning the fuel in the first place.
Green: uses 100% renewable energy to split water into hydrogen and oxygen. The oxygen output is also a key benefit of this process, with oxygen production being 8 times the mass of hydrogen produced.
Why Green Hydrogen?
♻️As a partial or complete replacement for natural gas, hydrogen fuel could provide a realistic route for decarbonisation of heavy industry by providing heat for industrial processes. Similarly, combustion of hydrogen could produce heat for district heating systems or replace natural gas as a source of domestic heating and cooking.
♻️In bottled or bulk form it could replace LPG (liquefied petroleum gas).
♻️Hydrogen is flexible and can be used in both combustion and fuel cells. Significantly, hydrogen can also provide an energy storage medium. It can be produced by electrolysis using surplus renewable electricity when there is greater generation than demand. It can be stored and used to generate electricity during periods of low solar or wind generation and also during dry weather events that limit hydroelectric generation.
♻️Hydrogen can be stored for a much longer time and greater capacity than electricity. It can also respond to seasonal variations in solar irradiance, or wind resources or low precipitation in dry years.
Has high energy density when compressed
Safety considerations similar to natural gas or petroleum
Produces clean power and fuel
Clean Industrial feedstock
Versality as an energy vector with wide application
Can be transported over long distances
Can be produced without a carbon footprint
Q&A
-
Brown: created by hydrocarbon-rich feedstock, such as fossil fuel, methane, coal. Creates as much CO2 as burning the fuel in the first place.
Blue: basically brown, but the CO2 created is then captured, and this must then be permanently stored somehow (a significant disadvantage).
Green: uses 100% renewable energy to split water into hydrogen and oxygen. The oxygen output is also a key benefit of this process, with oxygen production being 8 times the mass of hydrogen produced.
-
Hydrogen has similar safety requirements to natural gas (methane), and all modern hydrogen fuel cells, storage containers, and vehicles are designed with safety in mind for storage, transportation and refuelling.
-
Hydrogen refuelling is similar to refuelling with CNG. Simply drive up and refuel in a matter of minutes.
No significant downtime like EV.
-
Car: 1kg for approximately 110 km.
Bus: 20-30 kgs per day.
Truck: 20-30 kgs per day.
-
Hydrogen itself is 8 times lighter than a battery. So it depends on how you store it. For personal vehicles, hydrogen will have a similar weight, but a faster recharge/refuel time. However, in large commercial vehicles that need a long-range hydrogen becomes a much lighter alternative.
-
Hydrogen has 8 times more usable energy than diesel for the same weight.
Regardless of the process used to produce it, hydrogen can be either compressed or liquefied, and can be used:
✅ to fuel vehicles or stationary plants which are fitted with fuel
✅cells or internal combustion engines
✅ for heat by direct combustion or fuel cells
✅to generate electricity in dedicated hydrogen gas turbines
✅ to replace carbon in industrial processes such as steel production, and
✅for energy storage
Other Industry Applications
🟢Green Ammonia
Utilises hydrogen and nitrogen that can be extracted from the air to produce plant fertilisers.
55% of all hydrogen produced is currently used for the production of ammonia.
🟢Steel Industry
Hydrogen can replace coking coal in the steel making process.
Oxygen is also a key component in steel-making and can be collected from the green hydrogen production process.
Several pilot projects have recently been commissioned or are currently under construction.
Australian Case Study/ German Case Study/ Swedish Case Study
🟢Cement Manufacturing
Green hydrogen can be utilised instead of fossil fuels during the combustion process of producing cement.
🟢Fuel Production
Hydrogen is used to process crude oil into refined fuels, e.g. gasoline and diesel, and for removing contaminants.
Liquid hydrogen is also widely used as fuel for the American space program and by other countries and businesses launching satellites.
Hydrogen is also an important basic substance for producing methanol (which can be used as a fuel in internal combustion engines)

Green Hydrogen Production - a Modular System
The system has been developed by Clean Power Hydrogen (CPH2 ) a UK company that has patented a membrane-free electrolysis system for the production of Green Hydrogen.
Membrane free electrolysers are the new 'gold standard' in hydrogen production and FABRUM’s patented cryogenic technology is the ‘secret sauce’ for enabling membrane-free electrolysers to produce green hydrogen at market leading efficiency levels.
Through a process of using cryogenic cooling to separate the hydrogen from the oxygen, it delivers high purity hydrogen as well as high purity oxygen gases providing the potential for two revenue streams.
The Modular Green Hydrogen Production system can be scaled according to the changes in market demand.
Green Hydrogen is real and available now!
