Closing the hydrogen economic loop
July 21, 2008The inventor of the nickel metal hydride (NiMH) technology used for building batteries for countless portable electronic gadgets and now hybrid gas-electric cars believes the hydrogen economy is already upon us.
In a paper published in the current issue of the International Journal of Nuclear Hydrogen Production and Applications, Stanford Ovshinsky, Chairman and CEO of Ovshinsky Innovation LLC, based in Bloomfield Hills, Michigan, explains that we already have the means for making the hydrogen economy realistic.
Hydrogen is considered the "ultimate" fuel alternative to fossil fuels such as oil, coal and natural gas. As such, research is focusing on how to produce hydrogen from renewable resources in a sustainable way and finding ways to store it effectively and safely so that it can be released on demand for powering vehicles and producing electricity.
The global economy is based upon energy but society needs now, more than ever, a non-polluting fuel that requires no strategic military defense unlike oil. "The transition from fossil fuels to hydrogen is of revolutionary import not only for its societal impact but also for the new materials science that it absolutely requires in all of its aspects," explains Ovshinsky, "New science and new technologies build much needed new industries, which provide not only jobs but also feedback into the educational system."
According to Ovshinsky, the hydrogen economy, which will emerge from such technology, was kick-started with the introduction of the Ovonic nickel metal hydride battery used in hybrid vehicles. Reversible storage of hydrogen in a solid hydride permits the entire loop of hydrogen generation, storage and use, to be carried out now, rather than at some distant point in the future. Ovshinsky suggests that that despite the observations of some critics of the notion of a hydrogen economy, the creation of a fuel economy based on hydrogen, is not only practical and realistic but is available to our global society in the near-term.
He points out that by storing hydrogen reversibly in disordered solids, this solves the problems of storage, kinetics (speed of uptake and release) and cycle life. To this end, Ovshinsky and his colleagues have created a family of hydride compounds capable of real-world applications. Underpinning this is the vast catalytic surface area found in these materials, which means that when fabricated into thin film, continuous web, multi-junction devices, they can use the entire spectrum of sunlight to break up water to generate hydrogen, which is stored within the material ready for later use.

Scientists at the University of Leeds are turning low-grade sludge into high-value gas in a process which could make eco-friendly biodiesel even greener and more economical to produce.
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that the collagen can be used commercially.

The Hydrogen Economy by Jeremy Rifkin (Author) The road to global security," writes Jeremy Rifkin, "lies in lessening our dependence on Middle East oil and making sure that all people on Earth have access to the energy they need to sustain life. Weaning the world off oil and turning it toward hydrogen is a promissory note for a safer world." Rifkin's international bestseller The Hydrogen Economy presents the clearest, most comprehensive case for moving ourselves away from the destructive and waning years of the oil era toward a new kind of energy regime. Hydrogen-one of the most abundant substances in the universe-holds the key, Rifkin argues, to a cleaner, safer, and more sustainable world. |

The Hydrogen Economy by Jeremy Rifkin (Author) The message of The Hydrogen Economy is resoundingly simple: The earth is depleting its oil reserves and even the most generous estimates show oil reserves peaking in about forty years. The specter of global warming and the rise of Islamic fundamentalism in the oil-rich regions of the earth worsen the problem considerably. The answer, asserts Rifkin, is to embrace a new energy source that is just now gaining public attention: hydrogen. This abundant element, found everywhere on earth including in air and water, can be transformed, using sustainable methods, into a potentially limitless form of clean-burning fuel. But this potential will founder unless we act now to create the necessary global infrastructure before the factors above overtake us. If we embrace this momentous... |

60 Minutes - Schwarzenneger (December 21, 2008) Airdate 12/21/08 It's good that Governor Arnold Schwarzenegger likes a challenge. In December, he warned of financial armegeddon as California faced a huge budget deficit that threatened jobs, roads, schools, and public safety. At the same time, he's pushing some of the world's toughest environmental laws to make California a leader in fighting climate change. Throughout it all, he still loves to drive his Humvee.

Light, Water, Hydrogen: The Solar Generation of Hydrogen by Water Photoelectrolysis by Craig A. Grimes (Author), Oomman K. Varghese (Author), Sudhir Ranjan (Author) The development of a direct, inexpensive, and efficient method for converting solar energy into a portable, clean fuel would allow elimination of the growing problems associated with the ever increasing use of fossil fuels and the reality of their rapid depletion. As the title suggests, Light, Water, Hydrogen: The Solar Generation of Hydrogen by Water Photoelectrolysis, considers the combination of water and light with a suitable semiconductor to achieve a safe, renewable and therefore inexhaustable means for hydrogen generation via the splitting of the water molecule, or photoelectrolysis. The authors consider the impact of recent advances in nanotechnology on the water photoelectrolysis field, providing specific examples as well as the theories and methods necessary for... |

Power to Change the World: Alternative Energy and the Rise of the Solar City by S.L. Klein (Author) After WWII, in a memoir entitled "The Gathering Storm," Churchill described the buildup to war in terms that evoke uncomfortable comparisons. Today, the palpable sense of another storm gathering demands attention as the sources of instability, once underestimated, reach the headlines. But something crucially different underlies this new threat, something not seen before. While we have previously faced the growing popularity of utopian, totalitarian ideologies with global aspirations, we had not until now experienced a looming U.S. energy crisis inextricably intertwined with the threat. In the worst scenario, taking the brunt of this coming storm could result in a global economic, political, social, and ecological disaster. My book, which is the result of a uniquely broad-based,... |
