With the need for an alternative for fossil fuels and to reach net zero emissions by 2050, green hydrogen is quickly becoming a leading option for storing energy from renewables to tackle critical energy challenges.
What is Green Hydrogen?
Green Hydrogen differs from "blue" and "grey" hydrogen in that it uses electrolysis to separate the molecules allowing for zero carbon emissions, reducing the impact on the environment and assisting in the goal of net zero.
Other forms of hydrogen production use methane as a source for the production of hydrogen leading to the creation of carbon as a byproduct, whereas green hydrogen uses renewable energy as the source, avoiding carbon emissions.
Hydrogen provides an alternative to fossil fuels across industries and is a potential solution to providing renewable energy to areas that are unable to acquire renewable energy sources due to geographical difficulties.

A Green Future
Hydrogen has long since had the potential to be used as a clean energy source and with technological advancements and the pressure of climate change, the momentum behind the implementation of hydrogen as an alternative energy source has grown immensely.
A path towards net zero emissions is through the utlisation of green hydrogen. In the last few years hydrogen has seen a drastic decrease in cost due to technological advancements and it is predicted to fall by another 70% in the next decade.
The only way forward is with clean energy and renewable sources. Hydrogen is the most abundant element in the universe and provides a strong potential alternative to fossil fuels. In the transition to clean energy and net zero, green hydrogen plays an important role in accelerating the distribution of renewable energy.
