Hydrogenus Energy Limited (“HYE”) has developed and patented the modifications required for an Internal Combustion Engine (ICE) to be safely, effectively, and efficiently operated using hydrogen as its sole fuel.

HYE-ICE is designed for stationary applications, such as power generation. It has many technical advantages over other methods for remote, off-grid or back-up power, in that it:

Is circa 15% to 20% more effcient than a diesel engine
Maintains output at the desired speed better than any other engine
Adapts quickly to changes in load than any other engine

The HYE-ICE offers many commercial advantages:

The hydrogen is injected at low pressure
Does not require pure hydrogen
As it is an adapted diesel engine, it is likely to be familiar to most mechanics and as there is no carbon, there will be lower maintenance costs

As part of a system, the HYE-ICE can provide carbon-free electricity on demand at a lower cost than any other system for our target markets. HYE has been rigorously tested and is certified to Australian standards.

The benefit of hydrogen as a fuel in a combustion engine

The benefit of using hydrogen fuel is that it is a zero-carbon fuel, meaning that at the point of combustion, there is no residue or tiny solid and liquid particles suspended in the exhaust. These particles, often called soot or black carbon, are a mix of carbonaceous material, sulphates, nitrates, and other compounds.

The key benefits are:

Health & Safety: The removal of particulate matter means that there are no health or environmental impacts from operating a Hydrogenus engine. This is an essential consideration for meeting Occupational, Health & Safety (OH&S) requirements and Environmental, Social & Governance (ESG) obligations.
Lower Maintenance Cost: In the Hydrogenus Energy test facility, hydrogen fuel has been used for well in excess of five hundred plus hours of run time. During this time, the engine oil and engine condition have been constantly monitored with the findings that the engine oil appears virtually brand new, with limited to no evidence of bore glazing. This outcome will translate to lower maintenance costs over the short, medium and long-term life of the engine.
Engine Performance: The removal of particulate matter in the engine means little to no dirt in the engine oil and the engine itself, which is commonly referred to as bore glazing. Bore glazing is the buildup of particulate matter inside the engine. It appears as a smooth, polished layer that forms on the cylinder walls, reducing lubrication and creating suboptimal engine performance. The Hydrogenus engine does not experience bore glazing

Pure Water byproduct: The chemical reaction of burning hydrogen with oxygen produces a much larger mass of pure water. For remote locations or where water security is an issue, Hyrdogenus byproduct of pure water has advantages beyond the generation of electricity.

Hydrogenus Energy - Applications

Grid Forming

Hydrogenus provides an immediate back-up electricity supply for the grid or any other significant load requiring high-quality electrical power. It performs grid forming, with grid syncing, providing inertia to the grid to keep the current stable and avoiding voltage surges and tripping.

What is Grid Forming? Grid forming is a control capability of inverters in power systems that allows them to independently set and maintain the system's voltage and frequency, mimicking the behavior of traditional synchronous generators. A critical element for the successful introduction of intermitted renewable power such as solar and wind.

Grid Firming

Hydrogenus provides a practicable solution by storing surplus energy that would have otherwise been curtailed into hydrogen on-site. Using hydrogen as the battery enables renewable energy to be deployed into the grid at a time when demand is high.

What is Grid Firming? Grid firming is the process of balancing electricity supply and demand, particularly for variable renewable energy sources like wind and solar, by ensuring a reliable and consistent power output is available whenever needed.

Micro Grids

Hydrogenus provides a proactive response for communities, organisations, and industries that are disconnected from the grid, require backup energy, and/or are looking for alternatives to diesel-fueled generators.

Hydrogen can be sourced from “bottles” or produced on-site using electricity from wind turbines and/or PVs.

What is a Micro Grid? A microgrid is a localized energy network that generates, stores, and distributes electricity for a specific area, like a community or a large facility. Unlike a traditional grid, it can operate independently in a power outage.

Industry & Built Environment

Hydrogenus provides a bespoke energy solution suitable for most industry verticals. There is also the potential to take whole building off the grid when there is suitable space to locate an engine and storage.

Hydrogenus is an ideal solution for organisations that need to consider the ESG obligations.

What are Industry & Built Environments? Bespoke energy solutions for manufacturing facilities and mission critical infrastructure that need to meet ESG obligations and or secure backup facilities.

Data Centre

Hydrogenus dispatchable and or backup power for data centres, in that the response times to fluctuations in energy frequency are virtually instantaneous. A secondary consideration for data centres is that when burning hydrogen as a fuel, water is the natural byproduct. Water is a significant contributor to meeting the cooling requirements of a data centre.

What are Data Centres? A data center is a physical facility or location housing computer systems, servers, storage devices, and networking equipment needed to store, process, and distribute large amounts of data and applications for businesses and organizations.

Diesel Replacement

Hydrogenus presents an actionable and practicable solution for diesel engine (fossil fuel) replacement. By mid/late 2026 Hydrogenus is expecting to be able to demonstrate the ability to transport ammonium hydroxide to a location and then crack the liquid into hydrogen fuel on site.

Providing safe, price competitive fuel security for remote locations, using engine technology that is typically well understood.

What is Diesel Replacement? Diesel remains, in most circumstances, the default fuel for remote locations. Any more to reduce the cost, logistics and environmental impact of alocation is highly regarded.
