Green hydrogen technology
Understanding hydrogen as an energy carrier and the semantics behind its various names requires answering two essential questions: What is hydrogen, and how is it produced?
The difference between green hydrogen and blue hydrogen
What is blue hydrogen?
Blue hydrogen is produced when natural gas is split into hydrogen and CO₂ either by Steam Methane Reforming (SMR) or Auto Thermal Reforming (ATR), with the CO₂ then being captured and stored. By capturing these greenhouse gases, the environmental impact on the planet is mitigated.
The capturing is done through a process called Carbon Capture, Utilization, and Storage (CCUS)
The capturing is done through a process called Carbon Capture, Utilization, and Storage (CCUS)
What is green hydrogen?
Green hydrogen is produced using renewable energy sources such as wind or solar power through a process called electrolysis, which separates water into hydrogen and oxygen without emitting carbon dioxide. This method significantly reduces greenhouse gas emissions compared to traditional hydrogen production methods. Green hydrogen plays a crucial role in advancing sustainable energy solutions and reducing dependency on fossil fuels

First step
Production and Supply of Green Hydrogen
The production of green hydrogen encompasses several stages, starting with the extraction of seawater and culminating in the creation of hydrogen (H2) and oxygen (O2)
01
Extraction of seawater
The initial step involves obtaining seawater, as it serves as the abundant water source required for hydrogen production. Seawater's ready availability makes it a viable resource for this purpose
03
After desalination, the purified water undergoes electrolysis. Powered by renewable energy sources such as wind and solar power, electrolysis splits water into hydrogen and oxygen. This process involves passing an electric current through the water, causing the water molecules (H2O) to dissociate. Hydrogen ions (H+) migrate towards the cathode, while oxygen ions (O2-) migrate towards the anode
Hydrogen extraction using electrolyzes
02
Desalination of water
After extracting seawater, the next step involves desalination, which eliminates salt and impurities from the water. Desalination methods like reverse osmosis or distillation ensure the water is suitable for subsequent processes like electrolysis
Liquid Hydrogen storage
Second step
Liquid hydrogen offers advantages in terms of density and volume, allowing for more efficient storage and transportation of this clean energy carrier. Here are more detailed steps involved in the storage of liquid hydrogen
The storage of liquid hydrogen involves a specific process known as hydrogenation, which converts gaseous hydrogen (H2) into a liquid state
04
Insulation
Due to the extremely low temperatures required to keep hydrogen in a liquid state, proper insulation is crucial to minimize heat transfer and prevent the hydrogen from re-vaporizing. Insulation materials such as vacuum panels or multi-layered insulation systems are utilized to maintain the low temperatures inside the storage containers and minimize energy loss
06
05
Handling and storing liquid hydrogen requires strict safety measures due to its low temperature, flammability, and potential for rapid vaporization. Safety features such as pressure relief systems, venting mechanisms, and leak detection systems are incorporated into the storage infrastructure to ensure safe operation and prevent accidents
Storage containers
Safety measures
Liquid hydrogen is stored in specialized containers designed to withstand the extremely low temperatures and the pressure exerted by the liquid. These containers are typically double-walled and vacuum-insulated to provide thermal insulation and maintain the stability of the liquid hydrogen
01
Compression
Before hydrogenation can take place, the gaseous hydrogen is typically compressed to increase its density. Compression reduces the volume occupied by hydrogen gas, making it more manageable and suitable for further processing
03
As the hydrogen gas is cooled, it undergoes condensation, transforming into a liquid. At cryogenic temperatures, the molecular motion of hydrogen slows down, causing the gas molecules to come closer together and form a liquid phase. The liquid hydrogen is collected and stored in specially designed containers or tanks
02
Condensation
Cooling
After compression, the hydrogen gas is cooled to extremely low temperatures. The cooling process is achieved using cryogenic systems, such as liquefiers or refrigeration units, which employ various cooling agents like liquid nitrogen or helium
Hydrogen transfer
Third step
Advanced pipeline networks ensure seamless and secure transfer of liquid hydrogen from production facilities to shipping docks
Efficient Hydrogen Transfer Solutions
04
Cryogenic insulation
Throughout the pipeline system, insulation measures are employed to minimize heat transfer and maintain the low temperatures required to keep the liquid hydrogen in its liquid state. The pipelines are usually double-walled and vacuum-insulated to provide effective thermal insulation and prevent energy loss
06
05
The transportation of liquid hydrogen through pipelines is subject to regulatory requirements and safety standards. Operators must adhere to these regulations to ensure the safe handling, transportation, and transfer of cryogenic fluids. Compliance with regulations may involve regular inspections, maintenance activities, and adherence to safety protocols
Monitoring and safety systems
Regulatory compliance
Pipeline transportation of liquid hydrogen requires robust monitoring and safety systems to ensure the integrity of the pipeline infrastructure and prevent leaks or accidents. Sensors, meters, and monitoring devices are installed along the pipeline to continuously monitor parameters such as temperature, pressure, flow rate, and composition. Automated safety systems can detect any anomalies and trigger appropriate responses, such as shutting off valves or activating emergency procedures
01
Pipeline infrastructure
A specialized pipeline network is established to connect the hydrogen production facilities, where the liquid hydrogen is stored, to the shipping dock at the port. The pipeline infrastructure consists of a series of interconnected pipes designed to handle the transportation of cryogenic fluids, such as liquid hydrogen, at extremely low temperatures and high pressures
03
At the shipping dock, specialized loading and unloading facilities are installed to handle the transfer of liquid hydrogen between the pipeline and the transportation vessels, such as hydrogen carriers or tanker ships. These facilities include loading arms, couplings, and safety systems designed to handle cryogenic fluids
02
Loading and unloading facilities
Transfer stations
Along the pipeline route, transfer stations are strategically located to facilitate the transfer of liquid hydrogen between storage tanks and the pipeline. These stations are equipped with the necessary equipment and controls to ensure safe and efficient transfer operations. They typically include pumps, valves, pressure regulation systems, and monitoring instruments
Green Hydrogen shipping
Fourth step
Special shipping boats will be used to transport the liquid hydrogen from the port of Zarzis to ports in Europe for various users
The collected hydrogen gas is stored for various applications, while the oxygen gas can either be used for other purposes or released into the atmosphere
Electrolysis is an electrochemical process that separates water molecules into their elemental components, generating hydrogen gas at the cathode and oxygen gas at the anode
The production of 80 tons per day of green hydrogen, to be shipped through the port of Zarzis, Tunisia, will require 1.6 million MWh of electricity. This will be achieved through a combination of PV solar plants and wind farms connected to the local network of the national electricity company, STEG. 250 MW Electrolysers along with the process & storage facility shall be located within of the port of Zarzis
