XCMG XC968-EV is the representative work of XCMG’s third-generation pure electric loader. It adopts the industry's first "three-motor" technical solution, that is, the whole machine does not have a gearbox. This loader has the following features: Dimensions and load capacity: The dimensions of the XC968-EV are 5.4 meters high, 13 meters long, and 4.5 meters wide. The weight is 19,100 kilograms, and the maximum load capacity reaches 6,000 kilograms. Intelligent technology: The loader adopts XCMG's core independent power intelligent matching optimization technology to implement integrated intelligent control of the vehicle's motor power, speed, torque, etc. In addition, it is equipped with intelligent thermal management system, energy recovery and three-level fail-safe protection functions to achieve intelligent, efficient and safe operation of the entire machine. Environmental protection and energy saving: XC968-EV is a pure electric loader with zero emissions and no pollution. Its energy consumption cost is about 1/3 of that of a diesel engine, which greatly reduces energy usage costs. Applicable working conditions: XC968-EV is widely used in the environment of -40℃~50℃, and is suitable for steel plants, power plants, coking plants, coal chemicals, coal fields, sand and gravel materials, tunnels and other working conditions. The design of this loader replaces "oil" with "electricity", and the traveling system and hydraulic system are driven by electric motors, achieving pure electric, zero-emission operation. At the same time, it saves diesel engine maintenance costs and is more environmentally friendly and economical.

Aircraft fuel systems encompass a wide range of components, including fuel tanks, pumps, valves, filters, piping, gauges, and inserting systems. These components work together to store fuel, transfer it from the tanks to the engines, monitor fuel quantity and quality, and protect against potential hazards such as fuel leakage and vapor explosions. The aircraft industry is constantly seeking innovative and sustainable solutions to reduce greenhouse gas emissions and mitigate the environmental impact of aviation. Hydrogen fuel systems offer environmental benefits by reducing carbon emissions and minimizing pollutants. They also offer enhanced fuel efficiency due to the higher energy density of hydrogen. Advancements in hydrogen storage, distribution, and safety technologies are making hydrogen fuel systems more viable and reliable. Sustainable aviation fuel (SAF) is a liquid fuel presently employed in commercial aviation, capable of reducing CO2 emissions by up to 80%. It may be derived from various sources, such as waste oil and fats, green and municipal waste, and non-food crops. SAF offers environmental benefits by reducing greenhouse gas emissions and has gained regulatory and industry support, creating a favorable market environment.

ABS publishes requirements for hydrogen-fueled vessels American Bureau of Shipping (ABS) has developed and published a set of requirements to guide the industry in the use of hydrogen-fueled vessels.The ABS Requirements for Hydrogen Fueled Vessels offers the industry a risk assessment framework for introducing hydrogen as marine fuel to a fleet. The issued guidelines are building upon projects such as the ABS-classed, Glosten-designed hydrogen-fueled research vessel for the University of California San Diego’s Scripps Institution of Oceanography.The requirements regard, among other things, the following:Ship design and arrangementFuel containment systemMaterial and general pipe designBunkering and fuel supply to customersPower generation including propulsion and other energy convertsFire safety, explosion prevention and area classificationVentilationElectrical installationsControl, monitoring and safety systemsSurvey, manufacture, workmanship and testingTraining, drills and emergency exercisesOperationABS has also supported vessels such as Veer Voyage, a wind-powered containership with auxiliary fuel cell propulsion that utilizes green hydrogen as fuel, by leveraging the risk assessment defined in the new ABS document.ABS is working with leading organizations to support the safe development and use of hydrogen as a marine fuel. The requirements we have developed are a key step toward supporting vessels on their decarbonization journey… said Gareth Burton, ABS Vice President, Technology.To remind, ABS has also issued requirements for onboard carbon capture at sea.SEE THE REQUIREMENTS HERE Source link https://lnkd.in/ep-_aVW3

Achates Power and Argonne National Laboratory partnered on a project to develop a hydrogen engine for challenging-to-electrify long-haul vehicles. Using an opposed-piston design with compression ignition, the research team demonstrated the feasibility of creating a hydrogen engine. The opposed-piston engine, developed over a century ago and resurrected recently, offers advantages over conventional internal combustion engines, particularly in hydrogen applications. The streamlined design addresses heat loss and inefficiency, and with hydrogen's characteristics, it leads to increased power output in a cost-effective, lightweight, and simplified construction process—suitable for decarbonizing long-haul transportation.

Each technology approach has its place, advantages and disadvantages. Hydrogen ICE will have a large role, alongside fuel cells, battery, bio fuels and hybrid (as well as grid connection where possible). Good to see JCB looking at all of them. Of course the best way to reduce emissions is to reduce engine use.

From the latest issue of Aviation Week and Space Technology magazine: a graph (from Atkins) showing the energy required to produce aviation fuels. Kerosene releases more energy than required to produce it. The alternative power sources (eFuel: synthetic fuel, SAF: Sustainable Avation Fuel or biofuel) require much more energy to produce it than is transferred to propulsion. This underlines the large and very urgent tasks we face; requiring not only joint developments in the chemical, process, system, material, mechanical and stress engineering world but also in the financial and political fields.

Seven years ago, I covered Hitachi Zosen's Ariake Works. It was an extremely hot summer, just like now. At that time, there was no discussion about the use of methanol as a marine fuel, etc. Seven years later, technological innovations may contribute to the reduction of CO2 emissions from marine fuel. Hitachi Zosen Corporation announced on April 19 that its consolidated subsidiary Hitachi Marine Engine (HZME) will make a capital investment. The investment will amount to approximately 400 million yen. The company will establish technology to convert the engines of existing large ships to run on "green methanol," a fuel that can reduce carbon dioxide (CO2) emissions to virtually zero. In cooperation with a German company that is a major marine engine manufacturer, the company will begin converting the engines of ships owned by major shipping companies in fiscal 2024. Newly built ships will be the first to convert to methanol and other marine fuels. It is expected that the conversion of engines, which can reduce costs and construction time for existing ships, will promote decarbonization. HZME has received an order for a dual-fuel test engine (4S90ME-C10.5-LGIM) compatible with methanol from licensor MAN Energy Solutions SE MAN, and HZME will conduct technical verification through manufacturing and onshore testing at its headquarters and factory. Hitachi Zosen Marine Engine (Nagasu-cho, Tamana-gun, Kumamoto Prefecture) is owned 65% by Hitachi Zosen and 35% by Imabari Shipbuilding. Although Hitachi Zosen includes the word "shipbuilding" in its trade name, the company let go of its shipbuilding business in 2002 when it separated its shipbuilding and marine division from its headquarters. It continues to manufacture diesel engines and other products for ships. https://lnkd.in/gUgn3r9F ※Please feel free to ask me in case of you want to reach out your interview or an event to the Japanese shipping business community. yamamoto-h@jmd.co.jp Photo courtesy of Hitachi Zosen Corporation

It is amazing to see the progress in this future propulsion technology, especially as this goes hand in hand with agendas to diversify the energy market in countries like for example Saudi Arabia or Morocco.
