The construction industry is moving away from traditional diesel engines toward greener power solutions.

The upcoming edition of bauma, scheduled for 7-13 April 2025, will once again place a spotlight on alternative drive technologies.

Many major players in construction machinery are already committed to decarbonisation. For instance, the Volvo Group has announced that by 2040, it will only deliver fossil-free vehicles. Strabag SE, one of Europe’s largest construction firms, also plans to achieve full climate neutrality by 2040, encompassing the operation of all its construction machinery.

Electric motors are now firmly established as a sustainable drive option for construction equipment. At previous bauma events, exhibitors showcased electric-powered excavators, wheel loaders, rollers, dumpers, and vibratory plates as part of their expanding eco-friendly portfolios. This trend is poised for significant growth: research firm IDTechEx projects that the global market for electric construction machinery could reach US$105bn by 2042.

“Battery electric systems are still primarily suitable for compact machines. Their daily energy and power requirements can be covered by an electric motor and a moderately sized lithium-ion battery in conjunction with a well-defined charging strategy,” says Timo Feuerbach, technical expert for construction machinery and building material machines at the German Mechanical Engineering Industry Asso-ciation (VDMA).

The Bobcat RogueX2 concept loader belongs in this category as a current and pioneering example. The all-electric machine not only operates with zero local emissions, but is also fully autonomous, according to the manufactur-er’s specifications. This year, it received the prestigious Red Dot Design Award in the “Design Concept” category.

HVO as an alternative fuel

It is clear that openness to technology is required for drives that are as climate-neutral as possible across the entire spectrum of the construction industry. For example, a life cycle analysis commissioned by the Liebherr Group came to the conclusion that operating mobile cranes with hydrogenated vegetable oil (HVO) promises the greatest potential for reducing greenhouse gases. Other fuel alterna-tives that can contribute to decarbonizing construction sites are biodiesel, biogas and e-fuels.

Companies and research institutes are also focusing on developing and testing hydrogen powered construction machinery. The Liebherr Components product segment presented prototypes of two hydrogen combustion engines at bauma 2022, and series production was announced for 2025. The industry is also explor-ing potential applications for fuel cells. For example, General Motors and the con-struction machinery manufacturer Komatsu are working together on a hydrogen fuel cell module for an electric dump truck. Komatsu has also developed a medi-um-sized hydraulic excavator with a hydrogen fuel cell system as a concept machine.

Caterpillar Safety Services has introduced "MindShift for Leaders," a five-session training programme aimed at equipping leaders with the principles of human and organisational performance (HOP) to drive safer workplaces.

Designed as a virtual series, the sessions guide participants to rethink and adjust their approaches to leading and managing safety, encouraging a shift in mindset toward more resilient safety cultures.

"MindShift for Leaders" moves beyond traditional safety management methods, which often rely on policies and processes based on managerial assumptions rather than on the realities of how work is actually performed. The programme leverages HOP principles as a foundation to build error-tolerant systems, fostering open discussions around safety and supporting organisations in creating adaptive safety cultures that account for human variability and build resilience.

“Expecting perfection from workers is not realistic, and traditional methods of managing safety do not account for factors that can disrupt a system. A human and organisational performance mindset does not manage the incident itself but assists organisations with building more error-tolerant safety systems that allow people to stay safe, even when they make a mistake," said Zach Knoop, manager at Caterpillar Safety Services.

Five HOP principles

Human and Organisational Performance (HOP) promotes a mindset built on understanding human behaviour, communication, and responses in the workplace. Rather than following a strict process, it encourages organisations to create error-tolerant systems that drive learning and improvement without focusing on blame.

Caterpillar Safety Services’ “MindShift for Leaders” programme comprises five 90-minute virtual sessions, each centred around core HOP principles. The programme teaches that errors are inevitable and that protecting workers means designing systems that can withstand mistakes. Rather than assigning blame, the focus shifts to identifying and addressing organisational weaknesses that contribute to incidents. HOP also highlights that behaviours are driven by context; understanding the environment in which actions occur can reveal the real drivers behind decisions. Leaders are encouraged to create a culture of learning by valuing insights from workers who are closest to the job, promoting a flow of ideas that can prevent incidents and improve practices. Finally, the way leaders respond to mistakes has a profound impact on team morale, and the programme instills the importance of empathy and emotional intelligence in leadership.

“MindShift for Leaders” aligns with Caterpillar Safety Services' vision of a Resilient Safety Culture, underpinned by the principles of Mindset, System, Ownership, and Leadership, providing leaders with tools to foster safer, more resilient workplaces.

Niftylift is at the forefront in the mobile elevated work platform (MEWP) sector, offering some of the most fuel-efficient diesel-powered equipment, as well as hybrid and fully electric models.

Recently, it introduced the world’s first hydrogen-electric-powered access platforms – the HR15 H2E and HR17 H2E – marking a breakthrough in zero-emission construction in the Middle East.

"When powered by renewable energy, Niftylift’s fully electric platforms provide a dependable zero-emission solution for a wide range of urban jobsites. However, we recognise that not all projects, especially those in remote locations, have access to grid power for charging. This is where the hydrogen fuel cell comes into play. By adding it on top of the electric system, we offer a versatile and practical solution that’s viable for virtually any jobsite," explains Thomas Hadden, global technical sales manager at Niftylift.

The HR15 H2E and HR17 H2E can run for up to five days on batteries alone, with the hydrogen system doubling this range. Even with daily use, the hydrogen cylinder only needs replacing every two to three weeks. These boom lifts integrate hydrogen technology seamlessly, maintaining Niftylift's renowned low weight and compact design while emitting only water vapour and heat as by-products. This makes them ideal for both urban and remote sites, aligning with the region’s sustainability goals.

Johnson Arabia became the first rental company in the region to acquire a Niftylift HR15 H2E, impressed by its performance during a demonstration. The company also added 19 fully electric units to its fleet. The HR15 H2E is now operational on a high-profile UAE construction site, delivering zero emissions without downtime for refuelling or recharging.

Growth in the Middle East

Niftylift sees strong potential in the Middle East, driven by the focus on sustainability and safety in construction. “We’ve seen an ever-increasing growth for Niftylift products in the region even given the fierce market competition,” says Thomas. “This surge in demand is largely due to the heightened awareness of safety standards in the region and we are internationally renowned at Niftylift for our advanced safety features, such as SiOPS (sustained involuntary operation prevention system), load-sensing, and tilt-sensing technologies.”

To support growing demand, Niftylift is establishing a regional office in Dubai, serving as a hub for direct sales and support for key account rental companies. This will strengthen its partnerships in Bahrain, Kuwait, and Qatar, and expand its customer base in Saudi Arabia, a key growth market.

Niftylift also maintains close relationships with customers through regular face-to-face meetings and participation in industry events, including sponsorship of the International Powered Access Federation (IPAF) Middle East Conference 2024 in Riyadh.

“The Middle East’s transition to a sustainable future hinges on innovative technologies, such as hydrogen-electric equipment,” Thomas concludes. “As a leader in this field, we at Niftylift are committed to empowering the region’s construction industry to achieve ambitious decarbonisation goals.

At a recent seminar on climate-resilient solutions, Dr. Jacinta Dsilva, research director at SEE Institute, highlighted the critical need for sustainable urban planning to address the growing environmental challenges facing communities, particularly in the UAE and the Middle East.

With increasing urbanisation, the region is experiencing extreme weather patterns, including fluctuating temperatures and unpredictable rainfall, which pose threats to urban infrastructure and human well-being.

Dr. Dsilva emphasised that while developed countries have the resources to manage climate-related challenges, developing nations face more significant hurdles. She explained, “The challenge is these can be managed by developed countries. What about developing countries or countries that are dealing with much more climate-related challenges?” This gap, she noted, requires innovative, accessible, and affordable solutions.

Climate-resilient built environment

Among the key solutions discussed were nature-based approaches to flood resilience, such as wetlands. “Wetlands reduce flood risks by up to 40%,” said Dr. Dsilva, adding that creating such ecosystems in vulnerable areas could greatly mitigate the impact of climate change. She also pointed out the importance of addressing urban heat islands, a major issue in the Middle East. Implementing solutions like “cool roofs” and “urban forests” can reduce temperatures by 2 to 4 degrees Celsius, offering relief from the intense heat.

Dr. Dsilva also stressed the importance of incorporating sustainable urban design and green spaces into city planning. “Sustainable urban planning enhances both physical and mental well-being,” she said, explaining how walkable spaces, parks, and community events foster a sense of social connectivity and contribute to healthier communities. According to her, creating more opportunities for social interaction is crucial in today’s world, where digital distractions often isolate individuals from their neighbours.

Another vital area of focus is waste segregation and recycling. Dr. Dsilva highlighted the need for a circular economy, noting that “if we know how to segregate waste right from the source, we will be able to reduce at least 70% of the waste going to the landfill.” She commended the UAE government for its initiatives, such as the large waste-to-energy plant in Dubai, which is set to generate energy from organic waste.

As climate challenges intensify, Dr. Dsilva called for collective action: “We need to really work on SDG number six, which is clean water and sanitation.” She urged communities and governments to incorporate sustainable practices and technologies to build a more resilient future.
