CG Drives & Automation, a company based in Wernigerode, Germany, has announced the imminent market launch of modular inverter modules for hydrogen systems and fuel cell applications. These new modules are characterised by their low harmonics and high adaptability.
The new converter modules of the CG brand Emotron are designed to meet the requirements of existing hydrogen production and storage systems, the company from Saxony-Anhalt announced on Wednesday (13 March). At the same time, they fulfil THD standards. The integrated Emotron Active Front End converters (AFE) are said to be particularly short-circuit capable in order to compensate for voltage fluctuations and make power factor corrections "superfluous".
The AFE frequency converters from Emotron act as AC/DC rectifiers and regulate the DC loads in hydrogen production plants. In conjunction with the Emotron DCU (DC/DC converter), which regulates voltage and current, CG Drives & Automation aims to offer a "complete solution" that increases the efficiency of hydrogen production.
Bidirectional energy flow
The DCU offers a bidirectional energy flow. Energy can therefore flow in both directions. This means that the DCU supports fuel cell applications and battery energy storage systems. The modular converters from the Saxony-Anhalt-based company can build redundant systems. This improves the operational reliability of a hydrogen plant.
The integrated quiet rail filter solves common mode problems and reduces EMC interference. Emotron will also be exhibiting its new modular inverter solutions for hydrogen production at the HMI in Hanover from 22 to 26 April in Hall 13, Stand B77. Further information about Emotron can be found here.
Precise control for optimised hydrogen production
Inverter modules play an important role in hydrogen production, especially in the electrolytic production of hydrogen through water electrolysis. In this process, converters provide the electrical energy required to split water into hydrogen and oxygen.
The modules usually convert electrical energy from the power grid or from renewable energy sources such as solar or wind power into the form required to operate the electrolysis process. One of their tasks is to ensure that the electricity is available at the voltage and frequency required for electrolysis.
In addition, converter modules enable precise control and regulation of the electrolysis process to ensure consistent production of hydrogen and optimise energy efficiency. They can also help to adapt the operation of the electrolysis plant to fluctuations in the availability of renewable energy sources by modulating the energy generated accordingly.
