The Punjab Energy Development Agency has released a draft green hydrogen policy aiming to achieve a green hydrogen and ammonia production capacity of 100 kilo tonnes per annum by 2030. The policy proposes extending incentives under the existing “Punjab Industrial and Business Development Policy 2022” to new green hydrogen and …
The City of Delhi, with a human population of over 16 million has nearly 9 million vehicles on its roads running over 100 billion kilometers every year, spewing out nearly 4 million tonnes of fuel emissions into the atmosphere every year (9900 tonnes per day). About 2 to 5% of …
Introduction of catalytic converter in our automobiles played a vital role in the reduction of harmful emissions such as carbon monoxide, volatile organic compounds and oxides of nitrogen. The three-way catalytic converter which consists of platinum (Pt), palladium (Pd) and rhodium (Rh; Pt–Pd–Rh), while reducing harmful emissions also increases the …
Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of India’s environmental regulations. The air pollution regulations were effective at reducing ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide. The …
environmental sciences Foster care The large blue butterfly, Maculinea arion, knows how to fool ants into raising their caterpillars. But when the ant, Myrmica sabuleti, disappear there survival is at stake, a study has shown. The butterfly lays eggs on thyme flowers and the caterpillars fall on the ground after …
Researchers have found a new, efficient catalyst to convert ethanol and other biofuels into hydrogen - a discovery that could help make the use of hydrogen-powered cars more practical in the future. The catalyst - which was presented this week at the American Chemical Society meeting in Philadelphia -makes hydrogen …
Commuters' exposure to volatile organic compounds (VOCs) especially BTEX travelling in passenger cars in Kolkata, India were quantified in Phase I (2001–2002) and Phase II (2003–2004). Monitoring was made inside and in the immediate outside of passenger cars fitted with and without catalytic converters using different types of fuels, along …
Lemon juice spruces up not only exhausted humans but car exhausts too, say researchers from the Institute of Catalysis and Petrochemistry in Madrid, Spain. Their report appeared online in Environmental Science and Technology recently. Catalytic converters of cars that run on diesel become inefficient after the vehicles are driven for …
Robert C Stempel, former chairperson and ceo, General Motors, is largely credited for inventing the catalytic converter. In 1974 Corning, a us -based company, made the first catalyst substrates for autocatalyst manufacturers in the us. Catalysts were fitted into 1975 car models, marking the beginning of the gadget's exhaustive use. …
The Supreme Court in its order of 4.10.1999 called for suggestions regarding emissions control from two-wheelers and three-wheelers. The EPCA, in its earlier report of August, 1999, had made a brief recommendation that on scooters, which are high emitters of particulate, suggesting that the norms be tightened further, and the …
