Fuel Cell

As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.

Ethanol may be touted as a more eco-friendly alternative to fossil fuels, but it's not without its own drawbacks. Most importantly, the corn or other plants required as feedstock often take up field space that could otherwise be put to use growing food crops. Also, as with other plants, the feedstock crops require large amounts of water and fertilizer. Now, however, scientists at Stanford University have devised a method of producing liquid ethanol from carbon monoxide gas. Read More
In addition to the sporty and strange, the Geneva Motor Show hosts its fair share of green cars and concepts. This year, everyone from mainstream manufacturers to university teams showed designs built from ultralight components, powered by alternative fuels and otherwise designed around fuel- and emissions-frugal commuting.

Shipping ports are major sources of air and water pollution, due in part to anchored or docked ships using diesel generators to keep their onboard systems powered up. A year from now, however, the Port of Honolulu will be trying out a mobile hydrogen fuel cell unit, as a more eco-friendly and fuel-saving alternative. Read More
In revealing the all-new Intrado concept, Hyundai has set out to demonstrate how "advanced vehicle technologies and intelligent design can combine to engage more effectively with driver and passengers." The new concept combines aircraft-inspired design with a next-generation hydrogen fuel cell powertrain. Read More
Just as hydrogen fuel cell vehicles – big and small – start heading to the road, researchers at RMIT University in Melbourne, Australia, have come up with the concept of a proton flow battery that could expand the reach of hydrogen-based electrical energy systems as well as provide a potential alternative to lithium ion batteries.

Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.

I had a funny thought walking around the Toyota FCV concept, the company's new Fuel Cell Vehicle set to go on sale beginning in 2015: This could actually be the one, I thought to myself – this could be the first fuel cell vehicle we actually see on the roads in real life. Read More
Amongst the incremental improvements seen at CES, Toyota has announced its notable and progressive intention to begin selling hydrogen powered cars starting next year. Roll-out will begin in California initially and will continue around the world, it has confirmed. Read More
As we wind down toward the end of another year, it's time to take a look back at some of the innovations that helped make 2013 a big year for green car technology. Highly anticipated cars like the Porsche 918 Spyder and Cadillac ELR made their debuts, while green concept cars provided a peek at what the future holds. Our favorite eco-friendly concepts from the past 12 months rethink power technologies, aerodynamics and architecture to push fuel economies into the triple digits. Read More
