AEM Electrolysis to produce Green Hydrogen | Green Hydrogen Plant Setup | Corpbiz
In India, present Hydrogen production largely depends on fossil fuels through conventional methods has been contributing to #greenhouse #gas #emissions and climate change. But Using Anion-exchange membrane or AEM Electrolysis that uses renewable energy to produce Green Hydrogen is being seen as a promising solution for decarbonising the hydrogen manufacturing sector as well as many linked sectors such as transportation, industry, and power generation.
AEM electrolysis of water using renewable energy from solar, wind, and hydropower has the potential for industrial-scale production, reducing the cost of hydrogen production and increasing the efficiency of electrolysis. The price of hydrogen will be broadly determined by distribution and manufacturing costs.
The factors that drive the cost of AEM Electrolysis are the price of renewable energy and high investment costs. But with the strategic use of technologies present domestically and internationally and utilising the support and incentives that the government offers, setting up a Hydrogen manufacturing plant is possible
So what is AEM Electrolysis
AEM Electrolysis uses an electric current to split water molecules into hydrogen and oxygen. Electrolysis can be performed using two types of electrolytes: acidic electrolytes and alkaline electrolytes. In acidic electrolysis, hydrogen ions (H+) are produced at the anode, while oxygen gas (O2) is produced at the cathode. In alkaline electrolysis, hydroxide ions (OH-) are produced at the cathode, while hydrogen gas (H2) is produced at the cathode.
If we look into what is the Principle of AEM Electrolysis
AEMs are ion-conducting membranes that allow the transport of negatively charged ions (anions) while blocking the transport of positively charged ions (cations). In AEM electrolysis, water is split into hydrogen gas and hydroxide ions at the cathode, while oxygen gas and anions are produced at the anode. The hydroxide ion produced at the cathode side then reacts with the anions produced at the anode to form water.
Advantages of using AEM Electrolysis to produce Green Hydrogen
First is Higher Efficiency: AEMs electrolysis allows for the use of higher current densities through electrolysers, which can increase the efficiency of electrolysis. In addition, AEM electrolysis can operate at lower temperatures and pressures, which reduces the energy required for electrolysis.
Next is Low Cost: Using AEM Electrolysis is cheaper than the membranes used in conventional electrolysis, such as Nafion membranes. In addition, AEM electrolysis can operate at lower temperatures and pressures, which reduces the cost of the system components. Furthermore, AEM electrolysis can use low-cost and abundant catalysts like nickel or iron instead of expensive precious metal catalysts like platinum or iridium.
Compatibility with Renewable Energy: AEM Electrolysis is a technology compatible with renewable energy sources, such as solar power or wind, that can provide the electricity required for electrolysis. Using renewable energy sources can further reduce the carbon footprint of hydrogen production and increase the sustainability of the process.
The next benefit of AEM electrolysis is Scalability: SO AEM electrolysis can be scaled up for industrial-scale production of hydrogen. Using low-cost and abundant materials and compatibility with renewable energy sources makes AEM electrolysis a scalable and sustainable technology for green hydrogen production.
The potential market and the profit that can be made from this business will depend on factors such as:
• Hydrogen price for the end customer
• Available supporting infrastructure
• Local availability
• Competition for alternative technologies
Now Despite the advantages (Challenges of using AEM Electrolysis)to produce Green Hydrogen, there are still some challenges that need to be addressed by the proponent while choosing the machinery when setting up the plant to make this production commercially viable.
Membrane Stability
Catalyst Activity and Stability and
System Integration
But every new technology do have some Challenges of using in the initial stages of its implementation. Still AEM electrolysis has the potential to become a key technology for green hydrogen production. Many countries have already established such plants successfully and manufacturing green hydrogen profitably.
