Structural Batteries Pave Way for Light, Energy-Efficient Vehicles
When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group at Chalmers University of Technology in Sweden is now presenting a world-leading advance in so-called massless energy storage – a structural battery that could halve the weight of a laptop, make the mobile phone as thin as a credit card or increase the driving range of an electric car by up to 70 percent on a single charge.

Blueflite Hydrogen Fuel Cell Tech Revolutionizes Long-Range UAVs in Australia
–Blueflite is set to address the growing global demand for safe and reliable storage of hydrogen fuels for unmanned aerial vehicles (UAVs) through a collaborative early-stage project supported by the Northern Territory Government. The ambitious project, which will also see Blueflite open its Darwin-based premises, seeks to develop a lightweight, high-pressure, hydrogen vessel (tank) using Advanced Fiber Placement (AFP) technology pitched squarely at the underserved, long-range, UAV sector.
