EIA: China promoting both fuel efficiency and alternative-fuel vehicles to curb growing oil use
May 13, 2014
Consumption of gasoline in China grew from 0.9 million barrels per day (bbl/d) in 2003 to more than 2 million bbl/d in 2013, according to figures from the US Energy Information Administration (EIA). This continues a trend of significant growth in China’s transportation sector since the 1990s.
Increasing oil demand is requiring increasing imports; since 2009, China has been importing more than half of its petroleum needs. To counter this trend triggered by China’s rapid motorization, the Chinese government is adopting a broad range of policies, including improvements in the fuel economy of new vehicles and the promotion of alternative-fuel vehicles, EIA notes.

March 31, 2014
|Improvement in fuel consumption in India of a hybrid vehicle over a conventional vehicle. Click to enlarge.|
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.

ICCT provides policy update on proposed China Phase 4 fuel economy regulations
March 06, 2014
A team from the International Council on Clean Transportation (ICCT) has provided an update on China’s proposed Phase 4 fuel consumption standard for passenger cars. The proposal was published on 21 January 2014 by the Chinese Ministry of Industry and Information Technology (MIIT).
The proposed regulations cover passenger cars sold in China from 2016 to 2020, and project an overall fleet-average fuel consumption of 5L/100km (47 mpg US) for new passenger cars in 2020, as measured over the New European Driving Cycle (NEDC), from an expected fleet average of 6.9L/100km (34 mpg US) in 2015. This works out to an overall reduction of about 28%—6.2% annually—between 2015 and 2020.

Tesla shipped 6,892 Model S units in Q4 2013, 22,477 full year; battery Gigafactory announcement next week
February 20, 2014
Tesla Motors announced record deliveries of 6,892 Model S vehicles worldwide in the fourth quarter of 2013, with 22,477 vehicles in the full year. For the quarter, non-GAAP revenue was $761 million, up 26% from Q3. GAAP revenue for Q4 was $615 million, up 43% from Q3. Q4 non-GAAP net income was $46 million, or $0.33 per share, while Q4 GAAP net loss was $16 million or $(0.13) per share.
The differences between GAAP and non-GAAP are primarily due to lease accounting for resale value guarantee (RVG) and employee stock-based compensation as a result of the increase in stock price last year. The results show Tesla moving closer to break-even or profitability even on a GAAP basis. (GAAP net loss per share for the quarter ending 30 Sep 2013 was $(0.32), and for Q4 of 2012, $(0.79). For the full 2013 calendar year, net loss per share $(0.62), while for all of 2012, it was $(3.69).

|Average annual percentage of black carbon pollution related to Chinese exports. Credit: Lin et al. Click to enlarge.|
Chinese air pollution blowing across the Pacific Ocean is often caused by the manufacturing of goods there for export to the US and Europe, according to findings of a new study to be published this week in the Proceedings of the National Academy of Sciences (PNAS).
China is responsible for only a small percentage of the annual pollution in the US, but powerful global winds known as “westerlies” can push airborne chemicals across the ocean in days, particularly during the spring, causing dangerous spikes in contaminants. Dust, ozone and carbon can accumulate in valleys and basins in California and other Western states.

SAE New Energy Vehicle Forum: China’s focus on NEVs may have profound impact on future of transportation
November 13, 2013
China has a number of critical economic and environmental imperatives driving its pursuit of vehicle electrification, said the roster of plenary speakers at the SAE 2013 New Energy Vehicle Forum held in Shanghai this week. These include the increasingly problematic pollution and haze in cities; China’s projected increased reliance on imported oil; the need for rationalized multimodal transportation systems in ever more congested and space-limited cities; the growing dominance of the China auto market; and the desire to have China become the leader in the next generation of automotive technology, vehicles and mobility systems.
The shift from fossil fuels to electricity—while held in common with other countries—will be based on the “specific situation” in China, making the best use of China’s own advantages and innovations, but also with international cooperation, said Dr. Zhixin Wu, Vice President of the China Automotive Technology and Research Center (CATARC). The details of that specific situation may result in an electric vehicle parc somewhat different than in Western countries, other speakers noted, and may indeed—given the obvious scale of the China market—herald a major transformation in transportation, including the type and role of personal vehicles, others suggested.
IEA World Energy Outlook 2013 sees CO2 emissions rising by 20% to 2035; oil use on upward trend
|Energy demand growth moves to Asia. Source: IEA. Click to enlarge.|
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.

Nissan project in Beijing demonstrates Dynamic Route Guidance reduces fuel consumption and CO2 emissions
September 13, 2013
Results from Nissan’s New Traffic Information System Model Project in Beijing (earlier post) have demonstrated that Dynamic Route Guidance System (DRGS) can help alleviate traffic congestion and reduce fuel consumption. A simulation based on the project results suggested that when 10% of all traffic in Beijing used DRGS, due to reduced traffic congestion, travel speed throughout the city would increase by approximately 10% and both fuel consumption and CO2 emissions would decrease by approximately 10%.
DRDS distributes real-time traffic information from the traffic information center to onboard devices via telematics; the onboard devices show drivers the fastest route on the display. This large-scale project, involving 12,000 vehicles, is the first to demonstrate and measure traffic dispersion effects in a real setting.

|Aspirational targets among seven countries participating in the Electric Vehicle Initiative would see growth from just under 2 million EV and PHEVs to just under 20 million by 2020. Source: “Electric Vehicle Grid Integration”. Click to enlarge.|
A recently published paper by M.J. Bradley & Associates, commissioned by the Regulatory Assistance Project (RAP) and the International Council on Clean Transportation (ICCT), examines key drivers of EV adoption in the US, Europe and China, with an emphasis on vehicle charging scenarios and infrastructure.
This report examines hurdles to EV adoption in these regions, and identifies critical success factors that should guide policymakers in the transportation and electric sectors. Accelerating the pace of EV market growth requires a coordinated evolution in both sectors, the report argues, from the power plant to the charging station to the vehicle. Supportive policies should work to ensure that EV owners are able to capture the full economic value of their decision to fuel switch from electricity to gasoline, including any benefits to the grid operator, and any emission reduction benefits, in addition to realizing the savings from replacing gasoline or diesel fuel with electricity.
“Big data” analysis of Beijing taxi fleet suggests maximum electrification subsidy benefit from targeting medium-range plug-in hybrids
August 02, 2013
A pair of researchers at the University of Michigan have used “big data” mining techniques to evaluate the impact of adopting plug-in electric vehicles (PEVs) in the Beijing taxi fleet on life cycle greenhouse gas emissions based on the characterized individual travel patterns.
Although the results are based on a specific public fleet, the study demonstrates the benefit of using large-scale individual-based trajectory data (big data) to better understand environmental implications of fleet electrification and inform better decision making, Hua Cai and Ming Xu suggested in a paper published in the ACS journal Environmental Science & Technology. This research represents the first of a series of studies exploring the role of big data in environmental systems analysis for the emerging PHEV/BEV systems.
