Innovative Electrolyser Technology Transforming Green Hydrogen Production

The world of sustainable energy is witnessing a remarkable innovation that could reshape the way industries consider decarbonisation. Horizon Fuel Cell Group is on the verge of deploying the world’s first 5MW Anion Exchange Membrane (AEM) electrolyser by the end of 2025, targeting the production of cheaper green hydrogen. Over the past few decades, energy experts and business leaders have been keeping a keen eye on the emergence of technologies that not only promise a reduction in emissions but also offer cost-effective solutions to power heavy industries. Horizon’s new electrolyser technology is one such breakthrough that presents an appealing mix of efficiency and affordability. In this opinion editorial, we take a closer look at the AEM electrolyser, consider its potential to redefine sustainable production, and explore how it might soon become a cornerstone technology in the global hydrogen economy.

The development of this innovative system is particularly exciting because it tackles some of the tricky parts of conventional green hydrogen production. Traditional alkaline electrolysers, while proven in value, have often been associated with higher power consumption and capital costs. Horizon’s AEM system, on the other hand, claims to reduce power use by 10–20% compared to its alkaline counterparts. This is a game-changing improvement, especially given the ever-growing demand to generate clean energy without intensifying costs or diverting investment from other crucial areas. Industry players now have an opportunity to explore this new technology by working through the small yet significant twists and turns of adopting a system that could very well lower the levelized cost of hydrogen (LCOH) and, ultimately, provide an essential boost to markets across heavy industry sectors.

Integrating Photovoltaic Power with Electrolyser Systems

A key aspect that sets Horizon’s strategy apart is its innovative integration of photovoltaic (PV) technology with the electrolyser system. The deployment strategy involves working with a subsidiary of Rockcheck Steel Group Co. Ltd. in Tianjin, China, where the electrolyser is paired with a 17MW building-integrated photovoltaic (BIPV) system. This blended approach maximizes the use of renewable energy, effectively transforming intermittent solar power into a reliable source of green hydrogen. By doing so, the project not only demonstrates the viable coupling of solar energy and hydrogen production but also paves the way for future systems that could serve industries that require substantial energy inputs.

This integration addresses some of the confusing bits often found in standalone renewable power systems. In a typical setup, fluctuating energy outputs remain a nerve-racking challenge. However, the Horizon approach of marrying a large-scale PV installation with a set of multiple 5MW AEM systems is designed to harness and smooth out these variations. In practical terms, it means that as long as the photovoltaic panels generate power, the electrolyser systems can make their way through the process of producing hydrogen, regardless of the intermittency of solar input.

To clarify the benefits of this integration, consider the following list outlining its advantages:

Enhanced Utilisation of Renewable Energy – By synchronising PV output with hydrogen production, energy waste is minimised.
Reduction in Carbon Emissions – The hydrogen produced serves as a clean fuel replacement, which can directly reduce reliance on fossil fuels.
Cost-Effective Energy Storage – Green hydrogen can be stored and later used for diverse methods of energy generation, making it a versatile asset.
Scalability – The project lays a clear path for future projects that may integrate solar, wind, or other renewable resources with electrolyser systems.

Decarbonizing the Steel Industry: A Concrete Case Study

Steel production has long been viewed as one of the more challenging sectors in the fight against global carbon emissions. Traditional blast furnace methods rely heavily on coal, and any attempt to reduce emissions in this field has to first tackle these off-putting conventional methods head-on. Horizon’s groundbreaking project, developed in tandem with Rockcheck Steel Group, seeks to shift this paradigm by injecting green hydrogen into the gas pipelines used for blast furnace operations. Such an approach promises to reduce coal consumption for steel smelting significantly, thereby curbing carbon emissions immediately at the source.

The integration plan is based on a novel system that combines a 17MW BIPV installation with two 5MW AEM hydrogen production systems, delivering a subtle twist in how steel manufacturers can approach their energy needs. In effect, the green hydrogen produced is used during the smelting process as a supplement to, and eventually a replacement for, the use of coal. This can be understood as a significant step towards decarbonisation that moves beyond regulatory mandates and into real-world, cost-effective application.

Below is a simplified table summarising the critical aspects of the project implementation in the steel industry:

Component	Capacity/Scale	Purpose
Building-Integrated Photovoltaic System	17MW	Provides renewable energy input
AEM Electrolyser Systems	2 x 5MW (1000 Nm³/h each)	Converts renewable energy into green hydrogen
Hydrogen Injection into Gas Pipeline	N/A	Facilitates blast furnace operations with reduced coal reliance

This table provides an at-a-glance overview of how Horizon’s project is structured to introduce low-cost, green hydrogen into an industry that has traditionally been heavily dependent on fossil fuels. By tackling the tangled issues associated with decarbonising one of the most carbon-intensive sectors, Horizon is paving a path that not only benefits the steel industry but also offers a replicable model for other heavy industries.

Economic and Environmental Ripple Effects of Cheaper Green Hydrogen

The introduction of cost-efficient green hydrogen via Horizon’s AEM electrolyser systems carries with it implications that extend far beyond the immediate energy sector. With green hydrogen now on the brink of becoming more affordable, numerous downstream applications stand to gain progressive benefits.
