The urgent need to transition to sustainable energy sources has never been clearer. With the global push towards decarbonisation, the transport sector is under increasing pressure to reduce its carbon footprint.
In the UK, ULEMCo, a pioneering technology company, is making significant strides in enabling heavy-duty vehicles to operate more sustainably by leveraging hydrogen in internal combustion engines (ICEs) powered by diesel. Their innovative Hydrogen Dual-Fuel Technology (H2ICED®) offers a unique solution for cutting emissions while utilizing existing diesel engines, making it a pivotal player in the decarbonization of the commercial transport sector.
Understanding the Hydrogen Dual-Fuel Technology
ULEMCo’s H2ICED® technology provides a way to use hydrogen in combination with diesel fuel in heavy-duty internal combustion engines. This dual-fuel system reduces reliance on diesel, lowering carbon emissions while retaining the engine’s functionality and performance. The system injects hydrogen into the combustion chamber alongside diesel, improving combustion efficiency and leading to a cleaner burn.
How Does It Work?
The dual-fuel technology involves modifying existing diesel engines to run on both hydrogen and diesel. Here’s a closer look at the process:
-
1. Hydrogen Injection:
In a typical diesel engine, hydrogen is injected into the combustion chamber alongside diesel fuel. The engine continues to rely on diesel for ignition, but the hydrogen supports a more complete and cleaner combustion process.
-
2. Reduced Diesel Consumption:
By adding hydrogen to the fuel mix, the overall diesel consumption is reduced. Hydrogen, although less dense than diesel, has a higher energy content per kilogram. The dual-fuel system optimizes the ratio of hydrogen to diesel, ensuring the engine operates efficiently while reducing fuel consumption.
-
3. Cleaner Emissions:
One of the most significant advantages of using hydrogen is its cleaner combustion. Hydrogen emits zero carbon dioxide (CO2) when burned, resulting in a significant reduction in harmful emissions such as particulate matter (PM), nitrogen oxides (NOx), and other pollutants. The hydrogen-diesel blend significantly lowers the carbon footprint of the vehicle.
-
4. Seamless Integration into Existing Fleets:
ULEMCo’s technology is designed to work with existing diesel engines. This means that operators can retrofit their current fleets with hydrogen dual-fuel systems, avoiding the high costs and downtime associated with switching to completely hydrogen-powered vehicles. The technology integrates seamlessly with a variety of heavy-duty applications, such as refuse trucks, construction machinery, and road sweepers.
Use Cases for Hydrogen Dual-Fuel Technology
The flexibility of ULEMCo’s hydrogen dual-fuel technology opens up a wide range of use cases, particularly for industries that rely heavily on commercial and industrial vehicles. These vehicles are often used in applications where emissions reductions can have a significant impact on air quality and sustainability. Some of the most promising use cases include:
-
1. Refuse Trucks:
Waste management fleets, including refuse collection vehicles, are among the heaviest emitters in urban areas. By converting these vehicles to run on a hydrogen-diesel blend, ULEMCo’s technology helps municipalities reduce their carbon footprints while maintaining vehicle performance.
-
2. Road Sweepers:
Road sweepers, often operating in city centers, can greatly benefit from the technology. These vehicles typically have a high operational impact on local air quality, and retrofitting them with H2ICED® technology would reduce particulate pollution and improve overall urban sustainability.
-
3. Construction Equipment:
The construction industry, with its heavy machinery and vehicles, is a major contributor to emissions. Hydrogen dual-fuel systems can reduce the environmental impact of construction fleets while keeping equipment operational without significant downtime or overhaul.
-
4. Agricultural Machinery:
Agricultural vehicles, such as tractors and harvesters, often work in remote areas where fuel infrastructure can be limited. Using hydrogen alongside diesel allows these vehicles to maintain their operational range while reducing reliance on fossil fuels.
The Growth Potential and Market Impact
ULEMCo has seen significant progress in the adoption of its technology. While exact sales figures are not disclosed, the company’s recent funding rounds and strategic partnerships signal a growing demand for hydrogen dual-fuel systems. In May 2024, ULEMCo secured over £5 million in funding to accelerate the development of its hydrogen transport solutions. The company’s technology is already gaining traction, with hydrogen-enabled vehicles in operation in key UK locations such as Aberdeen, where more than 50 hydrogen-powered vehicles are currently deployed.
Furthermore, the UK government’s ambitious commitment to achieving net-zero emissions by 2050 provides a strong regulatory and policy framework to support the growth of hydrogen technologies. ULEMCo’s innovative solutions align with these national goals, positioning the company for significant growth in the coming years. The company is targeting the adoption of its dual-fuel hydrogen technology in up to 6,000 vehicles by 2030, and it continues to explore new funding options to scale its operations.
The market for hydrogen dual-fuel technology is poised for growth, driven by several key factors:
-
Government Support:
The UK government is heavily investing in green technologies and has set clear mandates for reducing emissions in transportation. This incentivizes the development and deployment of hydrogen solutions.
-
Economic Viability:
ULEMCo’s technology offers a cost-effective route to decarbonization by retrofitting existing diesel engines, making it a more affordable option compared to fully electric or hydrogen-only vehicles.
-
Demand for Cleaner Transport:
As businesses and municipalities increasingly focus on sustainability, there is a growing demand for solutions that allow them to reduce emissions without disrupting operations.
ULEMCo has reportedly collaborated with several local authorities and companies to retrofit diesel engines for hydrogen use, thereby reducing emissions and promoting sustainable transport solutions.
-
Aberdeen City Council:
ULEMCo has an ongoing partnership with Aberdeen City Council, focusing on the conversion of various vehicles to hydrogen dual-fuel systems. This includes refuse trucks, road sweepers, and other specialist vehicles. As of early 2023, ULEMCo was contracted to convert 35 vehicles, contributing to Aberdeen’s goal of reducing its carbon footprint.
-
Glasgow City Council:
In a significant initiative, ULEMCo commenced the conversion of 20 gritter and multi-purpose vehicles for Glasgow City Council. This project, supported by Transport Scotland, represents ULEMCo’s largest single deployment of hydrogen dual-fuel vehicles to date. The collaboration aims to assist Glasgow in its ambition to become Britain’s first net-zero carbon city.
-
