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.

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.

LanzaTech, a producer of low-carbon fuels and chemicals from waste gases, has partnered with the Centre for Advanced Bio-Energy, a joint venture between Indian Oil Corporation, Ltd. (IOC) and the Indian government’s Department for Biotechnology (DBT), to create a novel process for the direct production of low carbon fuels from industrial CO2 emissions.

LanzaTech and the Centre will leverage each other’s expertise to create a new process for the direct conversion of waste CO2 into drop-in fuels through an acetates-to-lipids pathway. LanzaTech has developed gas fermentation technology that can directly convert waste CO2 gases into acetates. (Earlier post.) The Centre for Advanced Bio-Energy is working to increase the production yield of lipids (oils) by “feeding” acetates to microalgae.
