In South Africa, there are several green hydrogen projects at various stages of development, as carmakers and truck companies continue testing work on the alternative energy source to establish feasibility, especially in the harsh operating conditions over long distances that make the Southern tip of Africa unique.
“Some notable examples are the ‘Hydrogen Valley’ feasibility study conducted by the DSI with partner companies, as well as the ‘Boegoebaai Hydrogen Cluster’ in the Northwest Province,” says Eric Parry, Senior Manager of Sustainable Solutions at Volvo Trucks South Africa. “Projects like these will enable the introduction and testing of hydrogen-fuelled commercial vehicles in South Africa.”
Volvo Trucks maintains that no single solution can solve climate change. Interest in sustainable transport solutions is growing locally, and the initial adopters in South Africa are companies that prioritise their environmental impact and already have emission reduction programmes in place.
Volvo Trucks is developing hydrogen-powered combustion engine trucks. Road tests with these hydrogen combustion engine trucks will commence in 2026, with a global commercial launch planned towards the end of the decade. Trucks powered by green hydrogen represent a significant step towards Volvo's net zero goal and support customers in achieving their decarbonisation targets.
Switching from fossil fuels to green hydrogen is one method to decarbonise transport. Hydrogen trucks are particularly suitable for long distances and areas where charging infrastructure is limited, or where there is insufficient time for battery recharging.
Volvo will begin customer trials of trucks using hydrogen in combustion engines in 2026, with commercial availability anticipated by the decade's end. Ongoing testing is already being conducted in laboratories and vehicles.These hydrogen-powered combustion engine trucks will complement Volvo’s other offerings, including battery electric trucks, fuel cell electric trucks, and trucks running on renewable fuels like biogas and HVO (Hydrotreated Vegetable Oil).
“Trucks with traditional internal combustion engines running on hydrogen will deliver the same performance and reliability as our diesel trucks, but with the added benefit of potentially low CO2 emissions from well-to-wheel. They will be a valuable addition to our battery electric trucks, which have been on the market for several years,” says Jan Hjelmgren, Head of Product Management and Quality at Volvo Trucks.
Volvo trucks powered by green hydrogen combustion engines have the potential to achieve net zero CO2 emissions when using renewable HVO as an ignition fuel and are classified as ‘Zero Emission Vehicles’ (ZEV) under the new EU CO2 emission standards.
“It’s clear that a variety of technologies are needed to decarbonise heavy transport. As a global truck manufacturer, we need to support our customers by offering a range of decarbonisation solutions, allowing customers to choose the best option based on their transport assignment, available infrastructure, and green energy prices,” says Hjelmgren.
Volvo's hydrogen-powered combustion engine trucks will employ High Pressure Direct Injection (HPDI), a technology where a small amount of ignition fuel is injected at high pressure to enable compression ignition before hydrogen is added. This technology offers higher energy efficiency, lower fuel consumption, and increased engine power.
Volvo Group has signed an agreement with Westport Fuel Systems to establish a joint venture utilising HPDI technology. This joint venture is expected to become operational in the second quarter of 2024, following formal closing.
