Producing an artificial leaf capable of harnessing Mother Nature’s ability to produce energy from sunlight and water via photosynthesis has been a long-sought goal for researchers aspiring to provide an environmentally-friendly way to free to world of its dependence on coal, oil, and other carbon-producing fuel sources. Now a group of Chinese scientists has presented a design strategy based on the chemistry and biology of natural leaves that could lead to working prototypes of an artificial leaf that captures solar energy and uses it efficiently to change water into hydrogen fuel.  Read More

We recently looked at a breakthrough in using sunlight to create hydrogen but now scientists have found a way to use ambient noise to turn water into usable hydrogen fuel. The process harvests small amounts of otherwise-wasted energy such as noise or stray vibrations from the environment to break the chemical bonds in water and produce oxygen and hydrogen gas.  Read More

Scientists at Emory University, Atlanta, Georgia, have built on feats of Mother Nature to develop the most potent homogeneous catalyst known for water oxidation, which they hope will lead to producing clean hydrogen fuel using only water and sunlight. Could cars of the future be powered by water and a solar collector on the roof?  Read More

You call that a laser? Now this is a laser. Laser Bay 1 holds half of the NIF's 192 beams

In their quest to be the first to trigger a nuclear fusion reaction using lasers scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) have delivered more than one megajoule of laser energy to a target. The peak power of the laser light, which was delivered within a few billionths of a second, was about 500 times that used by the United States at any given time and demonstrates the target drive conditions required to achieve fusion ignition.  Read More

Honda has begun work on a smaller solar hydrogen station prototype intended for use as a home refueling appliance. Capable of an overnight refill of fuel cell electric vehicles it is designed to be a single, integrated unit that will fit in the user's garage. Honda's next generation Solar Hydrogen Station, though not as big as the previous systems, will still produce enough hydrogen (0.5kg) via an eight-hour overnight fill for daily commuting (10,000 miles per year) for a fuel cell electric vehicle.  Read More

HydroLectricPower claims its HH2 system can turn just about any fossil fuel powered vehicl...

When the promoters of the HH2 Hydrogen Generator Clean Air Combustion System made an appearance at last year’s LA Auto Show they attracted their fair share of skepticism. Hardly surprising given their claims of boosting the horsepower, performance, and mileage of existing vehicles through the addition of an aftermarket device that mixes hydrogen and oxygen extracted from water with existing fuel. But the naysayers haven’t discouraged the system’s developers as they are fronting up to the LA Auto Show again this year with even loftier claims thanks to improvements to their system.  Read More

Known mainly for their potential application in hydrogen cars, fuel cells are a promising technology with several unresolved issues, including working temperatures. Scientist at the University of Calgary have discovered a new material that allows a common kind of fuel cell to work at higher temperatures, increasing efficiency while decreasing manufacturing costs.  Read More

The benefits of using hydrogen fuel cells to power UAVs have been shown by the Naval Research Laboratory (NRL) with its Ion Tiger UAV setting an unofficial flight endurance record of 26 hours and 1 minute while carrying a 5-pound payload. While taking advantage of hydrogen as a high-energy fuel, the electric fuel cell propulsion system onboard the Ion Tiger also boasts the low noise and signature of a battery-powered UAV.  Read More

Following on from the successful use of its Fuel Cell Vehicles (FCVs) in demonstration fleets in Japan and California, Nissan has announced its first commercial FCV lease in North America to Sacramento Coca-Cola Bottling Co., Inc. In an advantageous brand tie-in the zero emissions X-TRAIL FCV will be used by the bottler for sales calls and public events in the Sacramento area in promotion of its Coca-Cola Zero soft drink.  Read More

A team of researchers aims to educate people about the possibilities of hydrogen as a fuel by demonstrating the efficiency of fuel cells in two public transport buses that will operate in China’s North East. The University of Sunderland, UK, has joined forces with Shanghai’s Shen Li High Technology and local experts ComeSys Europe and AVID sustainable vehicles from Cramlington (Northumberland, England) to create ECO2Trans - the region’s first petrol-free passenger buses that will run on a fuel cell, battery and capacitor combination.  Read More
