Komatsu Ltd., led by president and CEO Hiroyuki Ogawa, has developed a concept version of its HD785 large dump truck, which boasts a maximum payload of approximately 92 metric tonnes, now equipped with a hydrogen combustion engine

The company has begun proof-of-concept testing at its Ibaraki Plant in Hitachinaka City, Ibaraki Prefecture. This initiative marks the world’s first instance of integrating a hydrogen combustion engine into a large dump truck.

Through these trials, Komatsu seeks to deepen its understanding of hydrogen engine applications, paving the way for the advancement of hydrogen-powered construction and mining machinery.

Innovating with hydrogen technology

As part of its commitment to achieving carbon neutrality, Komatsu continues to explore and develop alternative power sources.

In its pursuit of hydrogen engine technology, the company has leveraged the expertise of KEYOU GmbH, a German startup specialising in hydrogen engine solutions for heavy-duty trucks.

The concept machine integrates a hydrogen combustion engine and hydrogen tank system co-developed by Komatsu and KEYOU. To optimise hydrogen storage, the tank is mounted on a platform beside the operator’s cab.

Additionally, newly installed cameras and monitors both inside and outside the cab enhance visibility for the operator.

The proof-of-concept tests will assess key factors such as driving performance, operational duration, fuel efficiency, and safety measures associated with high-pressure hydrogen gas.

Advantages of hydrogen combustion engines

Compared to battery and hydrogen fuel cell alternatives, hydrogen combustion engines present a cost-effective solution for construction and mining equipment.

This is largely due to the ability to retain powertrain components from conventional diesel-powered machines, reducing the need for extensive modifications.

Moreover, with nearly zero CO_₂ emissions, some mining operators have shown interest in adopting hydrogen engines as part of their carbon neutrality efforts.

Challenges remain, particularly in hydrogen supply infrastructure and safety management. Komatsu plans to collaborate with industry groups and key stakeholders to address these issues and support the wider adoption of hydrogen technology.

Commitment to carbon neutrality

Under its mid-term management plan, Komatsu aims to cut CO_₂ emissions by 50% in both product use and production operations by 2030 (relative to 2010 levels), with the ultimate goal of achieving carbon neutrality by 2050.

The company has already introduced hydraulic excavators, tethered electric hydraulic excavators, and battery-powered excavators across various sizes.

Additionally, Komatsu is actively developing eco-friendly technologies, including carbon-neutral fuel solutions, battery-powered equipment power supply systems, hydrogen fuel cell-powered excavator trials, and a power-agnostic truck concept.

Komatsu remains dedicated to meeting diverse environmental demands through in-house research, open innovation, and strategic partnerships, reinforcing its commitment to a sustainable future.

Egypt’s Minister of Petroleum and Mineral Resources, Karim Badawi, spoke at the ministerial session of African Mining Indaba, held in Cape Town from 3–6 February 2025

The session, themed “Forging a United African Mining Front: Collaboration for Sustainable Development,” brought together key leaders, including South Africa’s Minister of Mineral Resources and Petroleum, Gwede Mantashe; the Democratic Republic of Congo’s Minister of Mines, Kizito Pakabomba Kapinga Mulume; and Zambia’s Minister of Mines and Mineral Development, Paul Kabuswe. The discussion was moderated by Marit Kitao, Director of the African Mineral Development Centre.

Badawi outlined Egypt’s progress in modernising its mining sector, emphasising that reforms are beginning to yield tangible results. He highlighted the country’s vast mineral potential and the government’s commitment to attracting investment through its new programme, which aligns with Egypt Vision 2030. The goal is to position Egypt as a key player in the global mining industry.

Modernisation

He also underscored Egypt’s dedication to fostering sustainable partnerships in the mining sector. He pointed to the recent finalisation of an updated Mineral Exploitation Agreement Model as evidence of efforts to enhance the investment climate. This new framework, he noted, is designed to create mutual benefits for stakeholders while supporting comprehensive modernisation strategies.

Further, Badawi detailed ongoing efforts to develop strategies for value-added mining industries and for managing the environmental and social impacts of mining activities. He also outlined the country’s strategy for maximising critical minerals to support the energy transition.

He announced plans for the Egyptian Digital Mining Platform, modeled after the Egyptian Upstream Gateway (EUG), which will offer detailed geological data and facilitate transparent investor engagement with the Egyptian Mineral Resources Authority.

Minerals Development Oman (MDO) said it will begin the export of its first copper concentrate shipment from the Lasail mine in Sohar, marking the revival of Oman’s copper mining industry after nearly three decades.

The Lasail mine, located in Block 11B, is operated by Oman Mining Company, a subsidiary of MDO. Producing high-quality copper concentrates with purity levels between 18% and 22%, the mine is set to enhance Oman’s role as a key supplier in the international metals trade. With an annual output of approximately 500,000 tonnes of copper ore, Lasail plays a crucial role in the country’s growing mining sector.

MDO is also preparing to commence operations at the Al-Baydha mine in Liwa between 2025 and 2026. Together, Lasail and Al-Baydha hold an estimated 2.78 million tonnes of copper ore reserves. The initial phase of redevelopment will span four to five years, with ongoing exploration aimed at expanding reserves and ensuring long-term production.

Revitalising Oman’s industries

Oman is aiming to cash in on the growing demand for copper globally, which is being driven primarily by electric vehicles and advanced battery systems.

Mattar bin Salim Al Badi, CEO of MDO, said, “We are pleased to contribute to the rich history of mining in Oman, which has been a center for copper mining for over 3,000 years. With a legacy pioneered by Oman Mining Company since 1983, today we celebrate the continuation of this heritage with the export of first shipment of copper concentrates from the Lasail Mine. The sector has made remarkable strides in exploration and extraction, enabling us to reopen dormant mines and maximise their value. These advancements not only strengthen the sector’s sustainability but also amplify its economic and social contributions.

The export of the first shipment from the Lasail Mine is a testament to our ability to transform challenges into tangible opportunities for growth. We are equally enthusiastic about the forthcoming operations at the Al-Baydha Mine, which will further enhance the value of this project and support the sustainability of Oman’s mining sector.”

MDO is actively conducting exploratory studies in surrounding areas to expand copper reserves. Additionally, the company is spearheading the Mazoon Copper Project, the largest integrated copper concentrate production initiative in Oman.
