Innovators at NASA have developed a variable-frequency, alternating current power system to enable turbo-electric and hybrid electric propulsion. The technology uses double-fed electric machines and a high-voltage, variable-frequency power system to significantly decrease (by 85%) the weight of an aircraft's power electronics for turbo-electric propulsion, while still providing high specific power and variable thrust.

LeasePlan Netherlands will collaborate with Dutch scale-up Lightyear, the first company in the world to develop an electric solar car for consumers. LeasePlan Netherlands will become Lightyear's leasing partner for the Lightyear One, the first car produced by the company. The Pioneer Edition of the Lightyear One is expected to drive on Dutch roads in 2020.

A research team have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Ports of Auckland has an ambitious goal to become a zero emissions port by 2040 and has recently completed the first step toward that goal by accurately measuring emissions and developing a plan to reduce them.

NASA is testing Alta Devices solar technology at the International Space Station in order to evaluate Alta's technology for future NASA low-Earth orbit missions, including powering CubeSats. Alta Devices also recently announced a new efficiency record of 29.1% for its single junction solar cell.

Argonaut Power, Ingenious' flexible energy platform, has partnered with Northumbrian Water to pilot the use of large scale battery storage at a number of the utility's sites across the North East, Essex and Suffolk.

Vauxhall will embark on an electric-focused technology drive, which will transform its range over the next two years at a similar rate to its first heady days as a car manufacturer at the start of the last century.

Researchers unveiled experiments with drones that can sense wind gusts and thermals, then use them to gain speed or altitude, just like birds do.

The company is investing ten billion euros in the expansion of the Mercedes-Benz Cars electric fleet and another billion euros in the global battery production network within the worldwide production network.

Scania is developing a fuel cell refuse truck together with Renova, a waste handling company in western Sweden. The truck will feature a fully electrified powertrain as well as an electrified compactor.

The joint study reports that the research team has opened new doors in the development of high energy-density batteries capable of meeting rapidly growing energy storage needs by overcoming the current temperature limitations of fluoride-based battery technology and by demonstrating the room-temperature operation of fluoride-ion based energy cells.

Amprius Inc is supplying advanced lithium ion cells to the Airbus Defence and Space Zephyr Program. Using Amprius' cells, which contain a 100% silicon anode, the Zephyr S flew more than 25 days, setting a new endurance and altitude record for stratospheric flight.

With interest in classic cars growing every year and values of heritage models at an all time high, Aston Martin Lagonda has pioneered a bold new plan: to future-proof these increasingly precious machines by creating the world's first reversible EV powertrain conversion.

The case against imports of e-bikes from China is in its final phase. In November, the Commission has published their General Disclosure Documents, through which they propose up to 79.3% duties on electric bicycles.

Rolls-Royce and Finnish state-owned ferry operator Finferries have successfully demonstrated the world's first fully autonomous ferry in the archipelago south of the city of Turku, Finland.
