The future of the global energy system is deeply uncertain, and the choices that are made in the coming years will have enormous consequences for the future of the climate and, indeed, human civilization. To understand how the energy system is changing, each year a variety of organizations produce long-term …
hydrogen can now be conveniently used as fuel without the usual hassle of storage and distribution. Scientists have developed a method to produce hydrogen on the spot for internal combustion engines from an alloy of aluminum and gallium. The alloy GaAl28 with 28 per cent aluminum by weight, has the …
could you be feeding spoonfuls of sugar to your car in the future instead of filling it with petrol? Not exactly but glucose could be a cheap source of hydrogen fuels for many things including the vehicles we drive. Researchers say they have found a relatively effortless way to extract …
What would you say of an industry that takes common salt and turns it into one of the most environmentally deadly substances we know of today, namely chlorine? And what if in its production process it uses yet another deadly substance, mercury? We are talking about India's caustic-chlorine industry. Centre …
See Score Card Raw material sourcing phase To rate the companies on the raw material sourcing phase, grp used the following indicators: the quality of input salt, transportation of salt, self-sourcing of water (water harvesting) and the use of renewable and clean fuels. The Indian caustic-chlorine industry has performed poorly …
Pondicherry-based Chemfab Alkalis Ltd (cal) has been rated as the greenest caustic-chlorine company in India. With an overall score of 46.7 per cent, it has been given the Three Leaves Award. Set up in 1985 by Krishnamurthy Rao, a technical expert, cal set the trend by going in for membrane …
Although there has been a belated shift from the polluting mercury cell technology to the membrane cells, mercury pollution in India is still very high. India does not produce mercury and relies completely on imports. Between 1998-2001, the annual mercury imports stood at 170-190 tonnes, which is 10 per cent …
It’s a Catch-22 situation. How does one rate an industry where the pollution is minimal at the production plant and peaks the moment the product leaves the factory gates? How does one rate an industry that is the mother of all chemical industries? How does one rate an industry that …
car radiators could be made the size of a matchbox if only they used a highly efficient heat exchanger developed recently at Bristol University, uk . The exchanger could also be used to build air-breathing engines for hypersonic aircraft (planes that can travel faster than the speed of sound). James …
