How Is Green Hydrogen Made?

Green hydrogen has gained prominence in the sustainability landscape. It can mitigate greenhouse gas emissions and lessen the public’s reliance on fossil fuels, and many businesses can benefit from its integration.

Like other business decisions, it is natural to be curious about the production process. Understanding how green hydrogen is made may seem complex, but it is relatively straightforward, especially when you partner with experienced specialists.

How Is Green Hydrogen Produced?

Green hydrogen is made through electrolysis. Depending on the equipment, you can draw out as much hydrogen as possible. Small-scale devices like fuel cells are used for portable hydrogen production, but large-scale production facilities are imperative in an industrial setting to ensure enough supplies and shoulder operation requirements.

Electrolysis consists of an anode and a cathode. Various materials make up these electrolytes, which separate hydrogen and oxygen. Ceramics are the leading choice, but liquid alkaline solutions are gaining traction as they extract and transport the water’s hydrogen ions from the anode to the cathode.

Green hydrogen has a sustainable reputation since it creates an energy source straight out of water. Unfortunately, about

rely on fossil fuels, which electricity is traditionally based on.

Some people are trying to modify the electrolysis process. For example, high-temperature electrolysis utilizes nuclear thermal energy to reach as high as 900 degrees Celsius. Most electrolysis processes use low temperatures, but this potentially includes steam as an assistive separator between hydrogen and oxygen.

Other subclasses mimic the heat necessary to produce green hydrogen. Solid oxide electrolysis cells are effective electrochemical devices that simulate the same temperature rates, making steam and electricity divide their properties together.

Co-electrocatalysis of carbon dioxide and steam is also a potential way to produce green hydrogen. Solid acid electrolysis cells cause a reaction that generates hydrogen gas, which can still be utilized for the same applications of this renewable energy.

The Uniqueness of Green Hydrogen

Many define green hydrogen as a clean power carrier for moving energy from one source to another. The chemical element can also be converted into different forms, whether mechanical or heat energy.

Green hydrogen is associated with terms like blue, gray and ****** hydrogen. While representing the same element, the latter options are not as eco-friendly as the former. The main difference is in their production.

Blue hydrogen is derived from generated carbon. Steam methane reforming

, carbon monoxide and a little carbon dioxide. The carbon this creates goes into a capture and storage system to minimize emissions.

Both actions cancel each other out regarding environmental impact, making blue hydrogen more carbon-neutral than green hydrogen. Another similar output would be turquoise hydrogen, which undergoes methane pyrolysis. It decomposes natural gas with thermal energy to draw out hydrogen and carbon.

Both low-carbon options are still more eco-friendly than gray hydrogen, which undergoes steam methane reforming. It omits the industrial carbon capture and storage system stage, which create a more negative outcome.

****** hydrogen is the most discouraged form, using ****** coal to create heat and produce this element. It goes against green hydrogen’s initial mission of minimizing emissions and easing dependence on fossil fuels.

Renewable Energy Sources for Production

Traditional electricity sources that use fossil fuels have the potential to create embodied emissions, which discounts decarbonization efforts. Thankfully, several renewable sources can substitute that power to uphold eco-friendliness.

Nuclear thermal energy is a clear candidate for high-temperature electrolysis. It has become more common, and many people classify it as pink hydrogen.

1. Solar Power

Solar power is one of the most popular energy alternatives, harnessing the sun’s rays to create electricity. In a global survey,

, while only 14% preferred fossil fuels. Using it in electrolysis can ensure emissions-free production and output.

Solar-powered electrolysis has become so common that many people call the product yellow hydrogen. Similar to pink hydrogen, this production method still ticks the boxes of how green hydrogen is made since it comes from clean power sources. The term is for extra specificity on material usage.

2. Wind Energy

Wind power harnesses the kinetic energy of the air to generate electricity. Depending on the wind turbine design, companies can draw in a lot of sustainable power. It is also used for electrolysis to produce green hydrogen.

While wind energy is highly efficient, placement and weather play a big part in production. People must dedicate large swaths of land to it, preferably in spaces with strong air around them. Turbine maintenance is also challenging.

3. Geothermal

Geothermal energy refers to heat underneath the Earth’s surface. It is more direct than nuclear thermal electricity, which uses atoms to kick-start fission and generate heat.

are more reliable since they are not dependent on external factors like the weather.

Geothermal power plants are becoming more popular, but questions surround their sustainability. You need to tap into the heat under Earth’s crust. Digging shifts the natural environment and creates tremors that make it more vulnerable to earthquakes.

4. Biomass

Biomass is renewable power derived from plants and animals. Wood, greenery, animal waste and so much more — collecting and heating them stabilizes the raw energy and serves as an avenue for electricity generation.

The main thing to work out with biomass is it is not readily available like the sun, winds or planetary heat. You must dry out the materials to ensure the moisture will not inhibit its overall energy levels. Heating should come from renewable sources to maintain green hydrogen status.

How Does Green Hydrogen Work?

The transport sector is one of the most popular industries benefiting from green hydrogen. The fuel cell of these vehicles consists of a small anode and cathode system, which performs electrolysis and creates green hydrogen.

Currently, about

are designed to handle more than 12,000 hydrogen fuel cell vehicles on the road. It costs around $13 per kilogram, but further developments in its storage may make it more affordable.

Green hydrogen also has a reputation for decarbonizing the chemicals industry. Ammonia is widely used to create soil fertilizer, but it is a common irritant that harms human health and the environment. Green hydrogen is a sustainable substitute that maintains the ***** and removes the *****.

Some also utilize green hydrogen as a heat source. Many manufacturing processes rely on fossil fuels like coal and petroleum to maintain high temperatures. This offers an opportunity to transition into cleaner energy.

Green hydrogen is mainly commercial, but many opportunities exist to use it in residential spaces. Traditional appliances like stovetops, furnaces and water heaters are dependent on natural gas. Replacing them with cleaner power is imperative to minimizing emissions. 

Challenges to Making Green Hydrogen

As beneficial as green hydrogen is, several hurdles may make it challenging to employ. Cost is a driving factor that makes the production less popular than its counterparts. A green hydrogen facility requires a big investment, especially for ******* projects.

One reason people may gravitate more toward blue or turquoise hydrogen is it is more cost-efficient. However, to achieve the global zero-emissions deadline, going low-carbon is not enough. Electrolyzers are projected to

in 2020 to just $634 per kW in 2050. This has the potential to increase electrical output energy, but it is dependent on how technology improves in the future and whether the core components also drop in price.

The pricing ties into the project’s scalability. Companies fully employing green hydrogen in their operations will need large batches at a time. The larger the scale of a facility, the heftier the supposed price. Complex infrastructure development can also raise expenses.

Extra considerations such as safety and training are also important. As simple as electrolysis may sound, it requires great precision. The slightest mismatch may cause grave accidents for workers and entail additional time to kickstart production.

Green hydrogen production requires plenty of electricity. Renewable sources are a great tool for keeping the process ecologically sound, but harnessing them takes time. This carrier is in high demand, which can raise questions about the efficiency of green hydrogen. 

Lastly, producers must also consider how green hydrogen production requires a steady flow of purified water. Any impurities can hinder electrolysis and result in contaminated hydrogen. Unclean water also damages the electrolyzer and make it unsanitized for future green hydrogen production.

If the world’s water supply
