Swiss marine power company WinGD says it has completed both Type Approval Testing (TAT) and Factory Acceptance Testing (FAT) for its ammonia-fueled two-stroke marine engine, marking what it described as a world first.
The tests were completed in January 2026 on the X52DF-A-1.0 engine at the Engine & Machinery Division of HD Hyundai Heavy Industries (HHI-EMD) in South Korea, witnessed by Lloyd’s Register together with representatives from major classification societies and under the supervision of EXMAR.
The 52-bore engine is scheduled to be installed on a 46,000 m3 LPG/ammonia carrier ordered for EXMAR. According to WinGD, the vessel series is expected to become the first ammonia-fueled gas carriers to enter commercial service, representing an important step in the shipping industry’s decarbonization efforts. The company said the development program demonstrated strong safety, reliability and performance results under a fuel pathway widely viewed as one of the more promising zero-carbon options for long-distance marine transport.
WinGD said the X-DF-A engine uses high-pressure ammonia injection with a pilot fuel dose of around 5% at full load, while delivering load handling, dynamic response and fuel efficiency comparable to equivalent diesel-fueled X-Engines in both ammonia and diesel modes. The company also said emissions results were encouraging, including NOx levels during ammonia operation that were below those generated in diesel use, alongside negligible contribution of N2O to the overall greenhouse gas emissions footprint. WinGD added that it has already secured an early orderbook of around 30 X-DF-A engines across multiple vessel segments.
Many alternative-fuel projects still sit at the concept or pilot stage. This one is different because it was executed on an engine destined for an actual commercial vessel program, under classification-society supervision and in cooperation with a yard ecosystem that can industrialize the result.
We talked with many industry representatives at CONEXPO, and we generally heard that the North American construction equipment market is performing relatively well and that it is expected to experience low single-digit growth in the near term, with demand remaining stable. Demand continues to be supported by infrastructure investment and ongoing construction activity.
OEM representatives said their cautious forecasts were affected by factors such as interest rates, inflation, tariffs and global supply chain disruptions.
Tariffs were repeatedly mentioned as one of the main uncertainties affecting the industry. Frequent policy changes are impacting equipment pricing, sourcing strategies, and global supply chains. Manufacturers are adjusting sourcing strategies and regional production to mitigate tariff exposure.
The industry is moving toward a dual technology pathway. Electrification continues emerging in compact equipment and adoption is increasing slowly as customers become more familiar with EV solutions. Advanced diesel engines remain dominant in medium and large machines, and according to experts, diesel will remain the dominant technology for a long time.
OEMs said they are investing heavily in new engine platforms, efficiency improvements, telematics and connectivity.
We were able to identify a number of trends, based on field interviews and observations conducted during OEM and engine manufacturer booth visits.
Powertrain, Engine Technology Trends
Diesel engines remain the dominant power solution for medium and large construction equipment. Large equipment used in remote areas still requires internal combustion engines due to power needs and operational constraints. According to interviews made by PSR, diesel will continue to be the preferred power solution.
Manufacturers continue to improve fuel efficiency, simplify engine architecture, and enhance durability. Manufacturers showcased different alternative power solutions and are still exploring and testing hydrogen combustion engines, hybrid systems, and introducing multi-fuel platforms (hydrogenated vegetable oil, hydrogen, biodiesel, and natural gas) to the market.
Several companies presented prototype hydrogen engine concepts, although these technologies remain in testing phases or with some few customers. One of the key operational challenges for hydrogen equipment is the lack of fueling infrastructure. As an example, Power Systems Research analysts interviewed executives of JCB, and the company explained that its hydrogen combustion engine technology is already on the field with a limited number of customers, although the market is still at an early stage of deployment.
JCB has developed a mobile hydrogen refueling unit in conjunction with a supplier company that delivers hydrogen directly to job sites, so the fuel logistics is handled as part of a service package supporting early adopters. The main takeaway from the interview is that hydrogen combustion technology is technically viable but still constrained by fueling infrastructure.
Regarding multi-fuel platforms, major manufacturers like Perkins and Cummins showcased engines designed to run on low-carbon fuels, including hydrogen, HVO, and natural gas, aiming to provide flexible, lower-emission solutions without sacrificing performance. Cummins next generation X15, and Perkins 2600 Series were showcased at the venue. FPT showcased it´s multi-fuel XCursor 13. Isuzu also presented it´s multi-fuel engine concepts based on its established engine architecture.
Electrification Trends
Compact equipment segments show the highest experimentation with electrification and alternative power solutions, while large machines such as dozers and large excavators continue to rely primarily on diesel power due to high energy requirements.
Electrification is primarily being applied to compact equipment used in urban environments, as well as in some remote applications supported by portable power stations or battery storage units.
Battery-electric prototypes and electric power units were showcased, with some already available in the market and others currently being tested as potential replacements for diesel engines in smaller and medium-sized equipment.
There is a growing trend toward presenting these technologies, and several new models were introduced during the show by different OEMs and engine manufacturers. Examples include the Perkins battery-electric power unit, the Komatsu electric micro excavator PC01E-2 made in Japan, the JLG scissor lift ES1930M Micro-Sized, the mini track loader TL100EV from Case, and the Dynapac CC1000e electric vibratory roller.
Charging infrastructure and operational limitations continue to restrict wider adoption of electric equipment across the broader construction equipment market.
Additional technologies presented included autonomous and robotic equipment, such as the RogueX3, Bobcats third-generation autonomous compact loader concept. This machine was introduced to explore the future of compact construction equipment through electrification, autonomy, and modular machine architecture.

80,800 units is the estimate by Power Systems Research of the number of Ag Tractors expected to be produced in North America (United States, Canada, and Mexico) during 2026.
This product information comes from industry interviews and from two proprietary databases maintained by Power Systems Research: EnginLink™ , which provides information on engines, and OE Link™, a database of equipment manufacturers.
2-Wheel Drive Tractors are farm tractors that have a drive train that allows two wheels to receive power from the engine simultaneously. Normally, the rear axle is powered by the engine.
4WD Articulated Ag Tractors are farm tractors built with an articulated chassis very similar to the design used for articulated wheel loaders. Each element of the articulated chassis has a rigid drive axle, and the front and rear elements are connected by a pivoting/ articulating joint. This design uses rigid (i.e. non-steering) drive axles and is typically used for large, high-HP tractors.
MFWD Tractors (Mechanical Front Wheel Drive) are farm tractors which feature a rigid chassis with steerable front-drive axles. This designation applies to both full-time 4WD and front-assist-drive configuration tractors across a broad HP range. Both configurations are produced in significantly greater volume than the 4WD Articulated type tractors.
Tracked Ag Tractors are steerable multitrack tractors with powered rubber tracks instead of wheels to move the vehicle. The crawler-type tracks are flexible and reinforced with steel. They are usually powered by hydrostatic or completely hydraulic driving mechanisms. They can be articulated or nonarticulated.
Trends. In 2025, production of Ag Tractors in North America decreased 6.2%. Production is expected to drop by nearly 6% in 2026.
Prior declines in 2020 were attributed to COVID-19 related issues which included unusually high orders for materials and parts. Inventory levels are at the lowest level in decades and have left the supply chain a mess, according to leading tractor manufacturers and AEM.
Production of machinery and components needed to build equipment has been halted. This negatively affected demand for farm machinery and contributed to overall lower sales and profits for agricultural equipment operations.
New tractors have become very expensive and have weakened demand. Reduced demand also has been linked to lower commodity prices.
The peak of Ag Tractor production was in 2013. Expect production to remain flat with a potential 10% decline by 2035. PSR

Following its Q4 2025 financial update, Tesla appears to be pivotally shifting away from its identity as a traditional automaker. By phasing out the Model S and X to focus on ‘Transportation as a Service,’ leadership is betting heavily on an autonomous-first business model.
And instead of building on that success, expanding into new segments, addressing affordability, and competing with the flood of new EVs from legacy automakers and Chinese competitors, the company that revolutionized the auto industry is walking away from it.
This Clean Technica article notes, “Arthur Bus’s collapse in Poland marks the end of a story that had been quietly unraveling for some time. A hydrogen bus startup backed by public funding, municipal orders, and a planned manufacturing footprint failed before delivering a single customer vehicle.
Tesla reportedly is positioned to receive roughly $165 million in California clean-truck incentives for its Semi.
As per the Times, the Tesla Semi’s funding will come from California’s Hybrid and Zero-Emission Truck and Bus Incentive Project (HVIP), which was designed to accelerate the adoption of cleaner medium- and heavy-duty vehicles. Since its launch in 2009, the HVIP has distributed more than $1.6 billion to support zero-emission trucks and buses across the state.
Boot Düsseldorf 2026 welcomed more than 200,000 visitors over nine days (Jan. 17-25) and hosted about 1,500 exhibitors from 120 countries. The show was about the same size as that of the 2025 event, but last year’s show drew exhibitors from only about 67 countries.
Boot once again confirmed its position as the world’s leading indoor boat show. The event covered the entire spectrum of the marine industry, including motorboats, yachts and superyachts, catamarans, sailing boats, outboard and electric boats, engines, power generation systems, equipment and components, as well as touristic services, charter companies, and boating clubs.
The superyacht industry enters 2026 in a phase of measured growth, supported by strong fundamentals. After several years of rapid expansion, the market is stabilizing and becoming more strategic, rather than slowing down. The global superyacht market reached approximately USD 21.6 billion in 2025 and is projected to grow to USD 45.16 billion by 2032, reflecting sustained long-term confidence in the sector. Today, more than 5,000 superyachts over 24 meters are in operation worldwide.
In 2025, 470 superyachts were sold globally, marking a 19.8% increase compared to 2024. Around 250–300 newly built yachts were delivered, including 10 yachts over 100 meters, a record year. Approximately 45% of market demand comes from charter activity, highlighting the importance of commercial readiness and high-quality guest experiences.
