EHS process enables cost-effective decentralised hydrogen supply for municipalities and industrial users

Munich, 20 December 2024 - E-world energy&water is the international meeting place for the energy industry. The Munich-based company SIQENS will be presenting its proprietary Electro-chemical Hydrogen Separation (EHS) method for hydrogen separation and purification at the leading European energy trade fair in the Hydrogen Solutions Forum, Hall 5 Stand 5L134.

Hydrogen is considered one of the most important energy sources on the path to decarbonisation. However, sustainable decarbonisation can only be achieved if green hydrogen is used. With the electrochemical hydrogen separation technology (EHS) developed by the Munich-based company, a significantly more energy-efficient process is now available than the electrolysis favoured by many. ‘The energy balance of the electrolysis process is sobering,’ argues Siqens CEO Dr Thomas Klaue. ‘The production of 1 kg of hydrogen using an electrolyser requires around 50 kWh, i.e. 50% more energy than is ultimately contained in the hydrogen at around 33 kWh. In addition, electrolysis has been on the market for a long time - its technical efficiency is considered to be exhausted by experts.’ This makes EHS a real alternative to electrolysis. SIQENS sees market potential for the process among plant manufacturers, energy companies and industrial users. EHS is also a viable option for local authorities with their natural and town gas networks.

Hydrogen obtained from waste
The EHS process is used to obtain hydrogen from natural gas, for example, through separation. The existing gas infrastructure serves as a transport medium. However, other locally available renewable resources such as biogas, methanol or methane can also be used for production. In principle, it is also possible to produce hydrogen from waste streams in this way - such as from biomass and non-biogenic municipal and industrial waste. The EHS process also allows hydrogen to be extracted from natural resources. Depending on the volume of hydrogen concentration in the feed gas, the energy required to produce 1 kilogramme of hydrogen with EHS is only 3-5 kWh, i.e. around a tenth of the energy content of hydrogen. The EHS process reduces the energy requirement by over 90% per kilogramme of hydrogen.
‘Electrochemical hydrogen separation is our technical solution to the central challenges of a cost-effective hydrogen infrastructure for decentralised hydrogen supply and the development of previously unused hydrogen resources,’ says Dr Klaue, summing up the economic advantages of the process. ‘Electrolysis, on the other hand, consumes a lot of electricity and is also expensive and time-consuming.’ At E-World energy&water, the experts from SIQENS will be demonstrating how the EHS process works in detail using a sample stack in the Hydrogen Solutions Forum, Hall 5 Stand: 5L134.

About SIQENS
SIQENS, founded 2012 in Munich, is a leading provider of methanol fuel cells and technology for electrochemical hydrogen separation (EHS). The Company’s methanol fuel cell product line (Ecoport) supplies clean energy in remote areas or backup power to critical applications. Built on its patented high-temperature polymer electrolyte membrane (HT-PEM) technology portfolio for power generation, SIQENS offers solutions to separate and purify hydrogen at the point of use from several feed gases – as from hydrogen-blends in natural gas pipelines or reformate gases from methanol or biogas. The SIQENS technology portfolio addresses the challenge of last-mile hydrogen distribution: Driving the decarbonization of power generation, transportation, and industry by reducing the cost of hydrogen delivery.
