Green Hydrogen

Green Hydrogen is Key to Achieving Net Zero

What Is
Green Hydrogen

Hydrogen is the simplest and the highest energy density molecule and is ideally suited to ‘carry’ energy.

In simple terms, “Green Hydrogen” is hydrogen derived from renewable forms of energy, such as solar and wind, in a process known as water electrolysis. Green Hydrogen essentially carries the energy from renewable electricity to power a wide range of use cases that today are driven by fossil fuels.

Green Hydrogen has the potential to decarbonize many industrial sectors, including power, heating, manufacturing, transportation, agriculture, and more. It is especially useful in decarbonizing sectors that can’t easily be directly electrified, where those carbon emissions are otherwise hard to abate.

The focus on Green Hydrogen is in response to the need for the world to achieve climate neutrality, to achieve Net Zero. Green Hydrogen is a necessary part of the solution.

The Problem

Today, fossil fuels (e.g., coal, oil, and natural gas) are the predominant source of energy globally. The exploitation of the fossil resources often releases methane, a potent greenhouse gas, and the combustion of fossil fuels produces carbon dioxide and other harmful pollutants.

The world’s reliance on fossil fuels has already caused the climate to change, with more frequent and extreme flooding, heat, and droughts as well as damage to the oceans and the loss of biodiversity. The world is nearing a tipping point where unabated emissions would lead to economic and human disaster.

A fundamental energy transition is needed, where just about everything is powered by clean energy.

The Urgent Need for Scalable Green Hydrogen Production

The world’s energy systems must be transformed from carbon-based feedstocks to being powered by renewably generated electricity. Low-cost production of Green Hydrogen is the critical electricity-to-molecule link for achieving Net Zero and helping humanity to avert an unrecoverable climate crisis.

Eliminating Carbon Emissions Is Essential

Increased energy efficiency and the direct use of renewable power are vital components of the solution, but cannot provide the whole solution. Certain parts of the economy are difficult to decarbonize because these require high-energy density fuel, reducing agents like coal-derived coke, or intense heat – and because renewable energy generation is not 24x7x365 always-on.

Green Hydrogen represents an efficient, scalable and effective solution that achieves deep decarbonization while addressing the needs of all sectors of the economy.

Advantages of Green Hydrogen

There are many advantages to using Green Hydrogen.


Hydrogen is abundant and virtually limitless. It can be produced wherever there is water and electricity. And it can be used at the point of production or transported to other locations.

Ideal Renewable Energy Carrier

Green Hydrogen is renewable energy locked into the lightest, simplest, and highest energy density molecule, storing clean, zero-carbon renewable energy for use.

Easy to Produce

Green Hydrogen is produced from a simple, three-atom molecule (water) in a reaction that is technically simple. An idealized, purpose-built electrolysis technology should be able to operate efficiently and with high output to generate Green Hydrogen at a cost only slightly higher than the cost of the renewable energy used to power the process.


Hydrogen contains almost three times as much energy by mass as fossil fuels, making it a highly efficient energy source by its very nature – and its high energy density means that a surprisingly low amount of water is consumed in the production of Green Hydrogen.


Green Hydrogen’s simplicity and energy makes it highly versatile. Not only can it decarbonize the hydrogen production industry, but it can also be combined with CO2 to make Net Zero gas, fuels and chemicals and Net Negative polymers. Plus, hydrogen and synthetic natural gas can be funneled through gas pipelines for business and home use.

The Future of Green Hydrogen

The future holds great promise for Green Hydrogen.

Global demand for Green Hydrogen will be massive. According to Goldman Sachs, Green Hydrogen will be a €10 trillion addressable market by 2050. A McKinsey study estimates the U.S. hydrogen economy could generate $140 billion by 2030. And countries around the world are recognizing the economic and climate opportunities of Green Hydrogen, giving it a major role in their Green Deal plans.
