WHY GREEN HYDROGEN?

A green hydrogen project refers to an initiative that focuses on producing hydrogen gas (H2) through a process that utilises renewable energy sources, such as wind, solar, or hydroelectric power, without producing significant carbon emissions.

Green hydrogen is considered a promising avenue for decarbonising various sectors, including industry, transportation, and energy, as it can serve as a clean and versatile energy carrier. Here’s an overview of green hydrogen projects:

KEY ELEMENTS OF

GREEN
HYDROGEN

PRODUCTION OF
GREEN HYDROGEN

Green hydrogen is produced using a process called electrolysis, where water (H2O) is split into hydrogen (H2) and oxygen (O) using electricity. This electricity is sourced from renewable energy systems (e.g., solar or wind farms), ensuring that the hydrogen production process is powered by clean energy, and the carbon footprint is minimised.

ELECTROLYSER
TECHNOLOGY

High-efficiency electrolysers are used in green hydrogen projects to convert water into hydrogen and oxygen. Proton exchange membrane (PEM) and alkaline electrolysers are common technologies employed in these projects.

SCALING AND
INFRASTRUCTURE

Some green hydrogen projects focus on creating large-scale electrolysis facilities, while others may target specific industries or applications. The development of hydrogen infrastructure, including transportation and storage, is crucial to enable the utilisation of green hydrogen.

RENEWABLE
ENERGY SOURCE

The primary objective of a green hydrogen project is to use renewable energy sources as the primary input for the electrolysis process. This ensures that the hydrogen produced does not contribute to greenhouse gas emissions.

INTEGRATION
WITH RENEWABLE
ENERGY FARMS

Green hydrogen projects are often co-located with renewable energy generation facilities, such as solar or wind farms. This allows the surplus renewable energy, which might otherwise be curtailed, to be utilised for hydrogen production during periods of excess generation.

MONITORING +
CONTROL SYSTEMS

Solar farms are equipped with monitoring and control systems that track the performance of individual panels and the overall system. This helps ensure optimal efficiency and identify any maintenance needs.

BENEFITS OF

GREEN HYDROGEN

Decarbonisation

By producing hydrogen without carbon emissions, green hydrogen projects contribute to reducing greenhouse gas emissions in sectors that are difficult to electrify directly.

Energy Storage

Green hydrogen can be stored for later use, providing a means to store excess renewable energy and balance energy supply and demand.

Energy Carrier

Hydrogen is a versatile energy carrier that can be used in various applications, helping to diversify the energy mix and reduce reliance on fossil fuels.

Economic Development

Green hydrogen projects can stimulate local economies by creating jobs in manufacturing, construction, operation, and maintenance of hydrogen infrastructure.
