Hydrogen

Nuclear fusion, just like the sun

Nuclear fusion has long been the holy grail of energy production. It is the process going on inside the sun, it is clean, and it has the potential to provide practically limitless power. Up until now nuclear fusion reactions have only been replicated inside hydrogen bombs due to the huge amount of power needed to start the reaction and keep it running, but scientists in Britain are hoping to change all that. Britain’s Telegraph newspaper is reporting that British scientists believe they are on the verge of achieving controlled fusion in a laboratory for the first time and will begin work this week to create a nuclear fusion reactor.  Read More

In photosynthesis, protons and electrons would be converted to carbohydrates for the plant...

An international team of researchers led by Monash University has used manganese, a chemical involved in photosynthesis, to split water into hydrogen and oxygen using only sunlight and an electrical potential of 1.2 volts. Scientists claim the process could provide a clean, cheap method of producing hydrogen for fuel cells and energy generation.  Read More

Carbon Capture and Storage slashes CO2 emissions into the atmosphere, but requires an incr...

Carbon capture and storage is a climate change mitigation technology characterized by sporadic and unreliable government support and plagued with accusations that it will worsen the environmental disaster it seeks to address. Yet, despite the negative stigma, CCS has been labeled by the IPCC and the Stern Report as an essential measure in reducing the impact of fossil fuels. Gizmag's Kyle Sherer takes a closer look.  Read More

The PANGAEA Expedition.

The 35-meter two master PANGAEA is the largest and most flexible polar expedition sailboat ever built. It can navigate through tropics and rivers as easily as it can through polar regions, and will travel to five continents, including the North and South Pole.  Read More

Hydrogen storage breakthrough

Hydrogen offers many benefits as a renewable and sustainable fuel of the future as its combustion emits only water. The main problem to now is that it must be stored as a gas, which is potentially dangerous for everyday use, and it can only be stored as a liquid under cryogenic conditions. Now there may be another alternative. Chemists in the US have developed a simple reaction to make ammonia borane (AB) – a powder more hydrogen-dense than even liquid hydrogen. AB is a stable white powder which releases hydrogen gas upon heating. Its use as a hydrogen storage material has been hampered by difficulties in making the powder in reasonable yield, but the new research further increases its promise.  Read More

Scorpion: hydrogen on demand system

Texas based Ronn Motor Company has lifted the wraps on a new environmentally friendly hybrid vehicle that features an in-built hydrogen on demand system. Currently in pre-production and due for release before the end of the year, the sporty “Scorpion” runs on a 30-40 ratio blend of hydrogen and gasoline, promising reduced emissions and 40 mpg plus efficiency.  Read More

A London black cab

May 23, 2008 While improvements in engine technology have led to a marked improvement in fuel efficiency and carbon emissions in vehicles running on internal combustion engines in recent years, even greater cuts in emissions need to be made to tackle the global environmental problems associated with them. We’ve seen commercial airlines turning to biofuels, trucks running on liquefied natural gas and buses using ethanol engines. One of the most promising solutions for the humble car of the future could is hydrogen fuel cell systems, with a number of car manufacturers investing heavily in development.  Read More

April 4, 2008 Here’s a futuristic, car-related technology you won’t see in the next summer sci-fi blockbuster: the algae-powered automobile. Some varieties of the unicellular plant are being tweaked to produce of hydrogen, which can be used to power efficient, environmentally clean vehicles. Researchers at the US Department of Energy’s Argonne National Laboratory believe that algae’s ability to grow pretty much anywhere will enable it to be the energy farm of the near future.  Read More

ITM and Roush Technologies to collaborate on hydrogen vehicles

April 2, 2008 Fifty million metric tons of hydrogen were produced in 2004, and the hydrogen production industry grows at an estimated 10% per year. But for hydrogen-powered cars to emerge as a serious competitor to fossil-fuel-powered transport there still needs to be substantial development of infrastructure. The latest push towards this goal in the U.K has seen ITM Power Plc and Roush Technologies Ltd sign a co-operative agreement that not only aims to put hydrogen-fueled commercial vehicles on the market within months, but also encompasses the development of hydrogen refueling station infrastructure that will enable vehicle operators to generate their own hydrogen supplies.  Read More

Carbon capture for automobiles

February 18, 2008 Carbon capture and storage has been touted as a method for slashing carbon emissions in power plants – now researchers at the Georgia Institute of Technology say it can be used to combat one of the most widespread greenhouse gas offenders: the automobile. Georgia Tech has outlined a concept system where carbon is isolated from fossil fuels, disposed of at a refueling station, and eventually recycled into new fuel. Not only is the closed-loop cycle carbon emission free, it is also renewable and efficient.  Read More
