What is a Silyzer?
Silyzer 300 is the latest, most powerful product line in the double-digit megawatt range of Siemens Energy’s PEM electrolysis portfolio. Silyzer 300’s modular design makes unique use of scaling effects to minimize investment costs for large-scale industrial electrolysis plants.
What are electrolyzers?
The electrolyser is an apparatus that produces hydrogen through a chemical process (electrolysis) capable of separating the hydrogen and oxygen molecules of which water is composed using electricity.
How much hydrogen does a 20 MW electrolyser produce?
The system can produce up to 8.2 tonnes of hydrogen a day using renewable energy, and will save about 27,000 tonnes of carbon dioxide (CO2) a year.
What is PEM green hydrogen?
Shell aims to reduce production of traditional fuels by 55% by 2030. The hydrogen will also contribute to decarbonising other industries. The project is expected to accelerate hydrogen production and contribute to Europe’s goal of carbon neutrality.
How does a hydrogen electrolyser work?
An electrolyzer is a system that uses electricity to break water into hydrogen and oxygen in a process called electrolysis. Electricity is applied to the anode and cathode across the proton exchange membrane (PEM) and causes the water (H20) to split into its component molecules, hydrogen (H2) and oxygen (O2).
What is green hydrogen electrolyzer?
Hydrogen electrolysers are devices that use electricity to split water into hydrogen and oxygen. When electricity input to the electrolyser is obtained from renewable sources like wind and solar, then the hydrogen produced is called green hydrogen.
How much is a PEM electrolyser?
A 2018 study by Fraunhofer ISE and IPA estimated the investment costs for a PEM electrolyzer that produces one standard cubic meter of hydrogen in one hour at around $7,600.
How does AEM electrolysis work?
In AEM electrolysis, a KOH electrolyte solution, with water molecules carrying OH– ions, is circulated to the anode side of the electrolyser. The liquid electrolyte hydrates the membrane and the catalyst layer on the GDL without an additional supply of (excess) water.
Are electrolyzers AC or DC?
Alkaline and PEM electrolyzers need to be supplied with DC voltages (from a few to hundreds of volt) and DC currents (from ten to thousands of amp). As a result, the use of AC-DC converters from an AC power supply (power grid, wind turbine) is mandatory [11].
What are electrolyzers made from?
Alkaline Electrolyzers Uses a liquid electrolyte solution such as potassium hydroxide (KOH) or sodium hydroxide (NAOH), and water. The hydrogen is produced in a “cell” which consists of an anode, cathode and membrane.
Who is Siemens gas and power?
With global headquarters in Houston in the U.S. and around 63,000 employees in over 80 countries, Siemens Gas and Power has a presence across the globe and is a leading innovator for the energy systems of today and tomorrow, as it has been for more than 150 years.
How is the Salzgitter electrolysis plant generated?
The necessary electrical power will be generated by seven wind turbines with a capacity of 30 megawatt. These will be erected by Avacon AG on the Salzgitter Group site and will likewise enter service from 2020. The heart of the PEM (proton exchange membrane) electrolysis plant is the Silyzer from Siemens.
Why choose silyzer 300 for electrolysis?
Silyzer 300’s modular design makes unique use of scaling effects to minimize investment costs for large-scale industrial electrolysis plants. The optimized solution results in very low hydrogen production costs thanks to high plant efficiency and availability. delivers nothing but pure hydrogen of the highest quality.
Why choose Siemens?
Siemens AG (Berlin and Munich) is a global technology powerhouse that has stood for engineering excellence, innovation, quality, reliability and internationality for more than 170 years.
