Hydrogen to power Japan’s new passenger jet by 2035

Posted by in categories: economics, energy, transportation

As AFP reports, in a meeting with industry experts, an economy ministry official outlined a target completion date of post-2035. To achieve this ambitious goal, a significant investment of five trillion yen ($33 billion) will be allocated over the next decade, fueling research and development of the new passenger plane.

This latest endeavor seeks to establish Japan as a leader in passenger aircraft production – a position it hasn’t held in over half a century. Building on the challenges that Mitsubishi Heavy Industries (MHI) encountered, which canceled its long-delayed passenger jet project in 2023, the new public-private consortium strongly emphasizes clean energy.

Electro-Fenton Magic Makes Methane the New Eco Fuel Hero

Posted by in categories: chemistry, energy, physics

A team from the Dalian Institute of Chemical Physics made a breakthrough in converting methane to formic acid using oxygen at room temperature through a high-pressure electro-Fenton process, achieving significantly higher efficiency and productivity than traditional methods.

Direct conversion of methane (CH4) and oxygen (O2) to value-added chemicals is important for natural gas industries. However, challenges remain due to the difficulty of O2 activation in forming active oxygen species for CH4 activation under mild conditions.

Recently, a research group led by Prof. Dehui Deng, Assoc. Prof. Xiaoju Cui and Liang Yu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) realized the electrochemical conversion of CH4 by O2 to formic acid (HCOOH) at room temperature. This study was published in the Journal of the American Chemical Society.

Rocket Explodes Seconds After Launch

Posted by in categories: drones, energy, satellites

A Japanese rocket by startup Space One has exploded in spectacular fashion following a launch attempt earlier today.

It’s yet another major setback for the company, which was hoping to become Japan’s first commercial entity to launch a satellite into orbit, the New York Times reports.

Drone footage shows the dramatic scene. At first, everything appears to go fine as the solid-fuel rocket dubbed Kairos lights its engines. But it doesn’t take long for the rocket to seemingly veer off path, erupting into a massive cloud of smoke just seconds later, causing major pieces of debris to rain down on the launch pad and engulf parts of the facility and a neighboring forest in flames.

Fuel-cell train travels more than 1,700 miles on one tank of hydrogen

Posted by in categories: energy, transportation

A hydrogen fuel-cell passenger train developed by Swiss rail vehicle maker Stadler Rail has achieved a new Guinness World Record, traveling for almost two days around the clock for a distance of 1,741.7 miles.

Efforts to clean up dirty trains are already well underway, with heavy investment in electrifying networks around the world as well as rolling out battery-electric locomotives such as the FLXDrive, the Blues train and the Flirt Akku.
