Hyzon’s Fuel Cell Trucks Challenge The Diesel Norm

Posted by in categories: energy, transportation

As a trailblazer in clean logistics, Hyzon continues to leverage hydrogen’s potential to fuel transportation innovations.


Hyzon Motors is making significant strides in revolutionizing the heavy-duty transportation industry with the production of its pioneering Class 8 200kW Fuel Cell Electric Truck. This milestone highlights the company’s dedication to advancing zero-emission technology and addressing sectors traditionally reliant on diesel.

The vehicle production results from a strategic partnership with North Carolina-based Fontaine Modification, which assembles the trucks by integrating Hyzon’s advanced fuel cell systems, battery packs, and hydrogen storage solutions into the chassis. This collaboration ensures each vehicle meets new standards in innovation and road-readiness.

Researchers Discover the Mechanism Responsible for “Self-Discharge” in Electric Vehicle Batteries

Posted by in categories: sustainability, transportation

Scientists identified a new mechanism causing lithium-ion battery self-discharge and degradation: cathode hydrogenation. They revealed how protons and electrons from the electrolyte impact the cathode.

LiMnO₂ Electrodes could Replace Ni/Co in Electric Vehicle Batteries

Posted by in categories: energy, sustainability, transportation

Lithium-ion (or Li-ion) batteries are heavy hitters when it comes to the world of rechargeable batteries. As electric vehicles become more common in the world, a high-energy, low-cost battery utilizing the abundance of manganese (Mn) can be a sustainable option to become commercially available and utilized in the automobile industry.

Currently, batteries used for powering electric vehicles (EVs) are nickel (Ni) and cobalt (Co)-based, which can be expensive and unsustainable for a society with a growing desire for EVs.

By switching the positive electrode materials to a lithium/manganese-based material, researchers aim to maintain the high performance of Ni/Co-based materials but with a low-cost, sustainable twist.

‘Massless’ battery promises a 70% increase in EV range

Posted by in categories: computing, mobile phones, transportation

Researchers say they’ve built and tested a ‘structural battery’ that packs a device or EV’s chassis with energy, saving a ton of weight. It could unlock smartphones as thin as credit cards, laptops at half the weight and a 70% boost to EV range.

EVs rely heavily – pun intended – on large lithium-ion batteries to cover long distances. Researchers at Chalmers University of Technology wondered if they could build a battery that doubles as the load-bearing material holding the car together, and shed some weight.

As part of their work on what they call ‘massless energy storage,’ the research team in Sweden has developed a battery made of a carbon fiber composite. It promises similar stiffness to aluminum, while also being capable of storing a fair bit of energy – enough to be used commercially.

Uber and Waymo to offer driverless rides in Austin

Posted by in categories: robotics/AI, transportation

“There are a bunch of stalls on campus where I go swing dancing. I guess those were the cruise ones,” says Dieck.

Last year, the self-driving car service Cruise suspended its fleet of nearly 1,000 cars nationwide following a hit-and-run crash, drawing concern about the partnership between Uber and Waymo, another robotaxi company.

“That might be one reason why I have never taken Waymo I would rather get in the car with someone who can maneuver, and you can see the rating that they have,” says Chester.

Most powerful fuel in history, created after Hawking predicted it: 8 grams for 1 million miles

Posted by in categories: nuclear energy, transportation

Hydrogen has been defined on numerous occasions as “the fuel of the future”. We have seen other alternatives, such as ammonia or even methanol (which you may remember meeting with us), but what if there was an even more powerful one? Hawking predicted decades ago that the most powerful one could exist, and now they have finally created it. This is the new engine that has everything to revolutionize the planet but would require a huge mobilization of resources to manufacture.

The idea of using thorium for fueling cars has created the immense interest from auto enthusiasts, as such cars may become a clean, efficient and almost inexhaustible energy source for transport in the future. Nevertheless, the prospects of this technology are not as simple as may be suggested by this example, and at the moment, this technology is still rather hypothetical.

A thorium-powered car engine concept is based on the use of the radioactive material known as thorium as fuel. In principle, this engine employed a tiny measure of thorium to release heat through nuclear fission, and the heat was further transformed into electricity to run the car.

Procedural Road Network Made With Unreal Engine 5

Posted by in categories: information science, robotics/AI, transportation

Game Developer jourverse, who is currently working on a tutorial series focused on building a traffic system in Unreal Engine 5, shared a demo project file for this procedural road network integrated with vehicle AI for obstacle avoidance, using A* for pathfinding.

The developer explained that both the A* algorithm and the road editor mode are implemented in C++, with no use of neural networks. Vehicle AI operations like spline following, reversing, and performing 3-point turns are handled through Blueprints. The vehicle AI navigates using two paths: the green spline for the main route and the blue spline for obstacle avoidance. The main spline leverages road network nodes to determine the path to the target via A* on FPathNode, which includes adjacent road nodes.

For obstacle detection, the vehicle employs polynomial regression to predict its future position. Upon detecting an obstacle, a grid of sphere traces is generated to map the obstacle’s location, and another A* algorithm is employed to create a path around the obstacle.

A capsule has been propelled through a Hyperloop test tube in a step forward for the transit system

Posted by in categories: Elon Musk, transportation

Hyperloop, a new form of mass transit involving capsules whizzing on magnetic fields through depressurized tubes, has achieved significant liftoff in the northern Netherlands, a company developing the technology said Monday.

A was levitated and zipped through a tube at a testing facility for the high-speed transit system once promoted by Elon Musk.

“So today, with the first successful test, we were able to levitate the vehicle, also turn on the guidance system and the propulsion system,” Marinus van der Meijs, the technology and engineering director at hyperloop company Hardt, told The Associated Press late last week before Monday’s formal announcement.

Goliath P1 solid-state EV battery defeats 1112°F thermal runaway

Posted by in categories: sustainability, transportation

A prototype solid-state battery, named the Goliath P1 and developed by UK startup Ilika, has made waves in the electric vehicle (EV) industry due to its significant benefits and implications. The battery achieved a major breakthrough by passing an important safety test known as the nail penetration test.

This test simulates a catastrophic incident that often leads to dangerous thermal runaway—a condition in which traditional lithium-ion batteries, which use liquid electrolytes, can explode or catch fire.
