H2 Core Systems

Hydrogen go!

Green hydrogen is set to drive forward the energy revolution. But how can this environmentally friendly energy source best be used in industry? There are various options, one of which comes from H2 Core Systems. The company’s modular technology solution – which is safely housed in enclosures from Rittal, is in global demand.

H2Core Systems, a system integrator, specialises in constructing systems that use electricity from renewable sources to convert water into ‘green’ hydrogen, which is then stored and made available for various applications. Depending on their size, the company’s modular systems can produce anywhere from one to 450 kilograms of hydrogen a day.

Everything in one enclosure 

Most inquiries come from two types of customers, says Uwe Küter, responsible for Sales and Business Development at H2 Core Systems: “Some have photovoltaic systems, want to use their electricity directly and are looking for ways to store it. The others need heat for industrial processes; so far, they have primarily been using natural gas, but now they want to switch to hydrogen.” The units offered by H2 Core Systems serve both purposes. 

Housed in 19-inch VX25-series enclosures from Rittal, they combine electrolysis units for producing hydrogen with modules and optional extras such as storage systems, compressors and fuel cells.

The modular baying system from Rittal enables us to combine our electrolysis units and scale them up or down to suit requirements, with anything from one to 40 units in a system. Another key advantage is the excellent stability of the enclosures. After all, a complete electrolysis unit can weigh as much as 500 kilograms.

During development stages, H2 Core Systems works closely with Berlin-based Enapter AG, which contributes its all-important AEM Electrolysers: “Enapter builds particularly small modules known as stacks. Besides their size, the other major advantage of these is their level of availability – if one stack in the system fails, the others continue to run.

Turnkey and easy to use 

With the Rittal enclosure system, H2 Core Systems can offer its range of solutions as a complete plug-and-play series. The systems are usually installed on the customer’s premises within a day, and normally, only one specialist technician is called for. Turnkey systems from Heide are in use in the UK, the USA, India and Brazil. Küter is convinced that “hydrogen has a huge advantage, namely that anyone can use it – any community, city or country anywhere in the world. All you need is a little water, wind and sun.”
