Methane Pyrolysis offers a method of creating hydrogen by disintegrating methane into its fundamental constituents, namely hydrogen and solid carbon, through a chemical process called methane decomposition. This innovative process has the potential to revolutionize the way we generate hydrogen as an energy source.

Green Hydrogen is a way that could help decarbonize the energy used faster and stabilize the planet's temperature significantly. Green hydrogen is produced by separating hydrogen and oxygen using electricity. This process is called Electrolysis. Pure water is supplied to the electrolyzer. Under the action of an electric charge, water is split into hydrogen and oxygen. Oxygen is released into the atmosphere or utilized. And the resulting hydrogen is captured. This hydrogen, called "green hydrogen" is an environmentally friendly source of both energy and a raw material, which is relatively easy to transport and store. The main advantage of electrolysis is that hydrogen is produced without the emission of harmful greenhouse gases. That is why it is known as pure hydrogen. Green hydrogen is also very versatile because it can be transformed into either a synthetic gas or electricity. It has various applications, including commercial, residential, transportation, and industrial uses.
Green hydrogen is an exceptional alternative to traditional fossil fuels and can be used in fuel cells to produce electricity. It is 100% environmentally friendly and does not emit any polluting gases either during the electrolysis process or during use. Hydrogen fuel cell technology produces a high-density energy source that is energy efficient. Hydrogen’s fuel efficiency enables a higher energy production per pound of fuel than alternative energy sources. It can also replace coal due to its high power generation capacity and can help reduce the industry's electricity costs. The cost of green hydrogen is largely dependent on the price of electricity without emissions and is estimated from 5 to 7 US dollars/kilogram, and longer term around 2 US dollars/kilogram.
The International Energy Agency put the cost of green hydrogen at USD$3 to $7.50 per kg, compared to $0.90 to $3.20 for generating hydrogen via steam methane reforming.
The cost of electrolyzers must be cut to reduce the price of green hydrogen, but this will take time and scale. However, the IEA says that electrolyzer costs could fall by half by 2040, from around $840 per kilowatt of capacity today.
Another problem is that green hydrogen requires very large amounts of cheap renewable energy because some is lost in the process of electrolysis. Shell says that electrolyzer efficiencies range from around 60-80%.
It is likely that developers, like Lightsource BP and Shell, will build green hydrogen production plants with dedicated renewable energy generation assets in high-resource locations.
Electrolysis is the process of generating green hydrogen using renewable energy sources such as solar, wind, and hydropower. This technique involves the use of an electric current to split water into its fundamental constituents, namely hydrogen and oxygen. The electricity utilized in this process is derived entirely from renewable energy sources, leading to zero carbon dioxide emissions and contributing to the prevention of global warming. As a result, electrolysis has the potential to play a critical role in achieving a more sustainable and environmentally-friendly energy future.

Green hydrogen is an incredibly versatile energy source that can be transformed into electricity or synthetic gas, and is suitable for a wide range of applications including commercial, domestic, mobility, or industrial uses. This clean and sustainable energy source produces zero emissions during the electrolysis process or when utilized, making it an ideal alternative to fossil fuels. Additionally, hydrogen fuel cell technology generates high-density energy that is efficient and provides more energy per unit of fuel than other alternative sources. This technology also has the potential to replace coal as a power generation source, reducing electricity costs for industries. While the cost of green hydrogen is largely dependent on the price of electricity, it is estimated to range from 5 to 7 US dollars per kilogram in the short term, and may decrease to 2 US dollars per kilogram in the long term.
According to the International Energy Agency, the cost of producing green hydrogen using electrolysis is estimated to be between USD$3 to $7.50 per kg, which is higher than the cost of producing hydrogen using steam methane reformation.
The cost of electrolyzers needs to be reduced to make green hydrogen more affordable, but this will require time and increased production. The IEA predicts that the cost of electrolyzers could decrease by half by 2040, from the current price of around $840 per kilowatt of capacity.
Additionally, green hydrogen production requires a significant amount of cheap renewable energy, as some energy is lost during electrolysis. It is likely that developers such as Lightsource BP and Shell may construct green hydrogen production plants with dedicated renewable energy sources in areas with abundant resources.
