If you want to help cut greenhouse gas emissions, you should probably skip the hydrogen fuel cell cars now coming to market and buy a (much cheaper) hybrid instead.
After decades of research and small-scale demonstrations, hydrogen cars are finally rolling into view. These vehicles use electric motors, but their electricity comes not from a battery but from hydrogen, processed in a chemical reaction that takes place inside a fuel cell.
Germany hopes to put one million electric cars on its roads by the year 2020, but government advisors already predict the country will miss its target if state support is not stepped up soon. EurActiv Germany reports.
The National Platform for Electro-Mobility (NPE) submitted its annual report to Chancellor Angela Merkel on Tuesday (2 December).
Hardware startup Navdy has raised a $6.5 million seed funding round for its connected car tech, which focuses on the heads-up display it created. The company had closed the funding officially before it ever began its pre-order campaign, which has netted the startup $2.4 million in committed orders since it began on August 5.
Supondrá un ahorro de un 30 % de batería. Se comercializará a corto plazo en toda la UE
Seis socios de Alemania, Francia, Austria y España han reducido el consumo de los vehículos eléctricos con un nuevo sistema inteligente de gestión y recuperación energética.

It’s estimated that more than half of U.S. energy — from vehicles and heavy equipment, for instance — is wasted as heat. Mostly, this waste heat simply escapes into the air. But that’s beginning to change, thanks to thermoelectric innovators such as MIT’s Gang Chen.
About four years ago, researchers in Michael Strano’s chemical engineering lab at MIT coated a short piece of yarn made of carbon nanotubes with TNT and lit one end with a laser. It sparkled and burned like a fuse, demonstrating a new way to generate electricity that produces phenomenal amounts of power.
At the time, no one understood how it worked, and it was so inefficient that it was little more than a “laboratory curiosity,” Strano says.
HySolarKit est un kit pour convertir un véhicule à moteur classique en un véhicule hybridosolaire. Le système permet de réduire les consommations et les émissions, avec un coût très faible par rapport à l'achat d'un véhicule hybride. Un véhicule ainsi transformé est capable de réduire de 20% la consommation et les émissions dans un usage urbain standard, sans sacrifier les performances, en améliorant même la capacité d'accélération et en maintenant l'autonomie du véhicule traditionnel.
Electric vehicle sales in Europe doubled again in 2013 for the fourth consecutive year, with more than one in every 20 new auto-buyers in the Netherlands and Norway opting for battery-powered cars, according to analysis of official data by the Transport and Environment (T&E) environmental think tank.
The paper found that 50,000 plug-in vehicles were sold across the EU in 2013 – 0.4% of all car sales – with the market set to grow to 100,000 vehicles by 2015, 500,000 by 2021 and 1 million by 2025, if the trend continues.
All electric vehicles currently in production use some form of lithium-ion chemistry in their battery packs.
Finding ways of improving that chemistry is therefore very important — the aim being to make future electric car batteries cheaper, more stable and more energy-dense for longer range.
Researchers from the School of Engineering at the University of Tokyo have found a way to develop a lithium-based battery with seven times the energy density of current lithium-ion batteries, according to Nikkei Technology.
En Allemagne, environ 8000 véhicules électriques circulent actuellement, sur les 43 millions de voitures immatriculées dans le pays. Les principaux freins à l'adoption d'un véhicule électrique sont un coût d'achat plus élevé, leur rayon d'action réduit, le manque de stations de recharge et la durée de cette recharge. Sur ce dernier point, la mise à disposition de supercondensateurs pourrait à la fois raccourcir cette étape et optimiser la récupération d'une partie de l'énergie lors du freinage.
