Singapore to Have First Hydrogen-Electric Bus Powered by Fuel Cells and Batteries

Researchers at Beijing’s Tsinghua University and NTU unveiled the first hydrogen-electric bus that will be from now on Singapore roads. Dubbed GreenLite, this eco-friendly bus only emits clean water and has zero carbon emission. Compared with other conventional buses, GreenLite does not run on fossil fuel and is powered by a combustion engine, which makes it very quiet.

Phantom Eye – Boeing's New Hydrogen Powered Spy Plane

Plane maker Boeing recently launched a hydrogen-powered spy unit that will stay aloft at 65,000 feet for up to four days. Dubbed Phantom Eye, it is one of the most environmentally friendly airplanes available today. According to officials, this unmanned aircraft can carry up to 450 lbs, having a 150-foot wingspan.

Honda Planning to Market Solar Powered Home-Based Hydrogen Refueler Starting 2015

Having your hydrogen fuel cell car powered by some solar panels in your own backyard looks like a dream not able to come true in a lifetime for some. For others, this is already a reality and a long-term plan. Honda, GM, Toyota, Mercedes and several other car manufacturers, joined by fuel providers including Shell, look at home-based refueling stations quite seriously and plan to have the first ones implemented in as little as five years.

MIT Researchers Discover Perovskite Sheets Can Improve Solid Oxide Fuel Cells' Efficiency

Sometimes, materials in bulk sizes exhibit properties totally different than when they are sliced in pieces only a few molecules wide. A news report from the MIT says that prof. Yang Shao-Horn and a team of researchers have discovered how a very thin sheet of a material called “strontium-substituted lanthanum cobalt perovskite,” aka LSC, can help solid oxide fuel cells (SOFC) produce a lot more electricity from the same amount of fuel.

Portable Fuel Cell Charger by Horizon, Now Available Commercially

Horizon, a fuel cell manufacturing company from Singapore, has recently unveiled a small hydrogen fuel cell charger that could juice your gadgets (PDA, phone, MP3, etc). It’s called MiniPAK, and it uses refillable solid-state hydrogen cartridges (called HydroSTIK) to store its power.

New Catalyst for Electrolysis Reduces Costs by 97% and Increases Hydrogen Production Fourfold

Hydrogen, the cleanest energy storage in the Universe, is most of the time associated with high costs, although it is extracted from water, which is the cheapest yet the most precious element to life. Extracting hydrogen from water is done through a method called electrolysis, but doing electrolysis efficiently requires the usage of catalysts such as platinum, which is very expensive.

Electrode Surface Texture: Key to Using Less Platinum in Methanol Fuel Cells

MIT researchers, along with their colleagues from the Brookhaven National Laboratory and the Japan Institute of Science and Technology have found a method of decreasing the amount of platinum used in DMFCs by increasing the efficiency of the fuel cell’s electrodes. Others have tried to replace the platinum on the cathode with a liquid regenerating catalyst system (catholyte solution).

Dealloying Process Creates More Efficient and Cheaper Platinum for Fuel Cells

Fuel cells are usually expensive because they use platinum as a catalyst. To make them more appealing to the market, researchers from the DOE’s National Accelerator Laboratory and the University of Houston, have created a new type of platinum catalyst, reducing the use of the pure metal down to 80 or even 70 percent, thus reducing the overall cost.
