With global warming showing no signs of a slowdown and carbon emissions reaching new heights, the need for efficient sources of clean energy is becoming increasingly urgent. Today, across multiple energy-intensive industry verticals, hydrogen is rapidly gaining momentum as a viable solution for storing and delivering clean energy. The highly volatile substance is not new in the sector, but solutions for realizing its long-recognized potential are only now becoming truly viable and scalable.

One technology solution provider that has succeeded in designing and developing a system for utilizing hydrogen effectively is Green Hydrogen Systems (GHS). Having spent the last decade rethinking and perfecting a process known as alkaline hydrolysis, the company has now successfully commercialized its primary technology: The HyProvideTM A-Series, the world’s first compact alkaline-based electrolyzer suitable for large-volume applications. This highly innovative energy conversion technology enables its users to easily transform excess power generated by renewable sources such as wind turbines and PV panels into green hydrogen, which can then be used as a fuel in different applications or simply stored for later use or further conversion.

Although alkaline-based electrolyzers have been around since the early 1900s, the sheer size of the early machines and the cost and time required to install them limited their use mainly to heavy industrial applications. They were, in any case, not suitable for use in decentralized, renewable energy supply systems that need to ramp up and down in mere seconds to accommodate dynamic, fluctuating power from wind and PV installations.

“We have taken this reliable, well-proven method and modernized it with a more compact size, greater efficiency and versatility, and a design that makes it easy to install across the many facilities where hydrogen is used,” explains Green Hydrogen Systems CEO, Niels-Arne Baden. With a plan to pitch green hydrogen as a core component of on-premise power storage and conversion solutions, GHS began commercializing its HyProvideTM A-Series dynamic alkaline electrolyzers in 2017.

In addition to the A-Series, which are intended for large-scale applications and for OEMs, the company’s smaller P-Series is a PEM system designed for use in microgrids and at research facilities that test different hydrogen applications.

A key point that distinguishes GHS electrolyzers is their standardized, modular design. This approach means that single units, normally installed in a standard-sized container, can be used individually for onsite production at a hydrogen refueling station, for example. To convert much larger amounts of excess energy, such as that produced at an offshore wind farm, multiple electrolyzers can also be clustered in a single system that maintains optimal load sharing operations while avoiding any redundancy. “If you have a storage solution for wind turbines or PV panels, the cluster operates continuously at optimal load, maximizing input efficiency and hydrogen output,” comments Baden. GHS also provides the software to manage the entire operation, further enhancing the control that operators and users have over the modules.

Green Hydrogen Systems is currently building a new combined factory and office complex to accommodate the growth the company is seeing. Going forward, the company plans to replicate its production setup at additional locations so it can more readily produce and distribute its electrolyzers around the world. “With our technology proven and already used in several applications, it’s now time to scale up production to bring the cost of green hydrogen down to parity with hydrogen produced using fossil-based energy,” says Baden. Once green hydrogen is available at same cost as “dirty” alternatives, Baden sees continued transitioning to this clean, storable fuel – and growing demand for GHS electrolyzers – as next to inevitable.
