Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty
September 04, 2014
Surface ozone pollution in India damaged 6 million metric tons (6.7 million US tons) of India’s wheat, rice, soybean and cotton crops in 2005, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union.
India could feed 94 million people with the lost wheat and rice crops, or about a third of the country’s poor, according to Sachin Ghude, an atmospheric scientist at the Indian Institute of Tropical Meteorology (IITM) in Pune, India and lead author of the new study. There are about 270 million Indians that live in poverty, according to the study.
Berkeley Lab study finds hybrids more fuel efficient in India, China than in US

In a pair of studies using real-world driving conditions, scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found that hybrid cars are significantly more fuel-efficient in India and China than they are in the United States due to traffic and driving conditions in those countries.
They found that driving a hybrid would achieve fuel savings of about 47 to 48% over a conventional car in India and about 53 to 55% in China. In the United States, hybrids are rated to produce a fuel savings of about 40% over their conventional counterparts. Currently hybrid and electric vehicles have a tiny share of the market in India and China and are seen as a higher-end product.
Tata and Westport introduce new 5L engine with GEMDi dual-fuel technology, new 3.8L SI gas engine

Westport Innovations Inc. unveiled its newest proprietary dual-fuel technology: Westport gas enhanced methane diesel (Westport GEMDi), applied to Tata Motors’ new 5-liter dual-fuel methane-diesel engine. Westport GEMDi technology enables engine original equipment manufacturers (OEMs) to offer a fully integrated, high performance engine optimized for dual fuel operation.
Westport co-developed GEMDi technology with Tata Motors on the next-generation 5L engine, targeting medium-duty trucks and buses in India. This technology provides fuel flexibility, beneficial in regions where natural gas infrastructure is emerging, such as India, and is designed to meet Euro IV and V emissions standards.
IEA World Energy Outlook 2013 sees CO2 emissions rising by 20% to 2035; oil use on upward trend

The newly released 2013 edition of the IEA World Energy Outlook (WEO) depicts a world in which some long-held tenets of the energy sector are being rewritten; importers are becoming exporters, while exporters are among the major sources of growing demand. However, the report advises, long-term solutions to global challenges remain scarce; as one example, the report sees global CO2 emissions rising by 20% to 37.2 Gt by 2035.
WEO-2013 presents a central scenario (“New Policies”) in which global energy demand rises by one-third in the period to 2035, although energy demand in OECD countries barely rises and by 2035 is less than half that of non-OECD countries. China is about to become the largest oil-importing country and India becomes the largest importer of coal by the early 2020s. The US moves steadily towards meeting all of its energy needs from domestic resources by 2035. Together, these changes represent a re-orientation of energy trade from the Atlantic basin to the Asia-Pacific region, according to the report’s scenario.
Australia CSIRO and India CSIR launch A$6M partnership on dimethyl ether
October 10, 2013
Australia’s CSIRO and its equivalent in India, the Council of Scientific and Industrial Research (CSIR), have launched a three-year, A$6-million (US$5.6-million) collaboration focused on improving processes involved in the production of dimethyl ether (DME), a clean-burning synthetic liquid fuel.
DME is non-toxic and non-carcinogenic and can be produced from natural gas (NG), coal, biomass, or even directly from carbon dioxide. It offers diesel-quality performance with a high cetane number and low auto-ignition temperature, but burns cleanly without producing any soot. The carbon intensity of the DME will vary with the feedstock.
