Each week, Mike Millikin of Green Car Congress brings WorldChanging readers the best of the week's sustainable transportation news. Here's this week's installment:
Policy and Legislation
It was a big week for policy and legislation. Probably the most reported was the Senates approval of opening up drilling in the Arctic National Wildlife Reserve (ANWR). The decision is notable for many obvious reasons, not the least of which are the potential environmental impact and how little a quantitative effect ANWR would have on the purported goal: energy independence.
Just on the numbers side, given government estimates about production volume, timing, and the ongoing increase in oil consumption in the US, ANWR would reach its peak production in 2024 at less than 1 million barrels per day, reducing the forecast US reliance on imported oil then by four percentage pointsfrom 70% to 66%. (GCC)
Even if ANWR were at peak production today, the US would still be importing than 9 million barrels per day.
ANWR oil, in other words, doesnt make much of a dent. Match that with the risks of arctic drilling and the potential environmental impact, and you have bad policyassuming the goal is to reduce dependence on imported oil. Strong efforts on conservation combined with an aggressive fuel efficiency program would do much more in a much shorter period of time.
But one of the themes that began to emerge during the ANWR debate from some drilling supporters is one that will be refined and used often as global oil production approaches and then passes its peak over the next few years: there is no such thing as a bad energy source. In other words, if its there, drill it. Every drop will be needed.
That argument will become more widely compelling to a broader base depending upon the timing of peak production and the state of demand globally for oil. It also does not address the underlying problem, nor would the resulting solutions, like ANWR, make enough of a difference in sufficient time to warrant the diversion. Its bad math, bad environmental stewardship and bad policy all rolled up into one big mass.
Separately, Republican Senators re-introduced legislation for a national Renewable Fuels Standard.
The new measure would reportedly require 6 billion gallons of renewable fuels be blended into the nations fuel supply annually by 2012. This represents a 1 billion gallon (20%) increase from the amount initially proposed in the RFS proposed in 2001.
But 6 billion gallons in 2012 represents only 2.8% of projected 2012 gasoline and diesel fuel consumption in the US. By comparison, the European Union has set an intermediate target of a 5.75% renewables component for its fuels by 2011, with 20% being the goal for 2020. (GCC)
In Canada, the federal government says it plans to regulate greenhouse gases as pollutants under the purview of the Canadian Environmental Protection Act, and will introduce a bill to that effect as early as next week. (GCC)
The Washington state House passed a bill adopting Californias emission standards for light- and medium-duty passenger vehicles. While this would put Washington in the LEV-II/PZEV/ZEV camp, it does not include the provisions of the more recent Pavley Bill that restricts CO2 emissions from new vehicles. (GCC)
Washington would be the ninth state to adopt Californias lower emissions standards instead of the federal standards.
Hybrids
The Burbank, California city council approved spending some $350,000 to work with Californias South Coast Area Quality Management District (AQMD) to convert five Toyota Priuses to hydrogen-electric hybrids for testing and use in the Burbank fleet.
The converted cars will use hydrogen as a fuel in the existing internal combustion engine rather than gasoline. The Toyota Hybrid Synergy Drive will be unmodified.
As part of the initiative, first proposed by AQMD in June 2003, the agency will spend $1.4 million to convert the Priuses and build the requisite hydrogen fueling station for the city.
Quantum Technologies is developing and integrating the hydrogen internal combustion engine fuel system.
Japanese truck makers are accelerating their rollouts of hybrid models, especially diesel hybrids.
Toyotas Hino is currently the market leader in Japan. Domestic sales of hybrid trucks and buses surged 14-fold in 2004 from a year earlier, due largely to the brisk sales of Hino's Dutro Hybrid light truck, released in November 2003. Hino is expanding its presence in North America.
Earlier this year, Hino released a new version of its diesel parallel hybrid bus in Japan. The new system improves fuel consumption by 10%20% and reduces CO2 emissions by 9%17% over conventional diesel buses.
Isuzu Motors, Japans top seller of trucks and buses in 2004 excluding 660cc minivehicles, is due to release a lightweight diesel hybrid ELF-series truck using Isuzus own hybrid system this spring. Mitsubishi Fuso Truck & Bus Corp., the No. 2 player in 2004, plans to release a similar vehicle by year-end. Mitsubishi Fuso introduced a diesel series hybrid bus last year. (GCC)
On a retrospective note, DaimlerChrysler CEO Dieter Zetsche in a speech to the Detroit Economic Club said that several automakersincluding DaimlerChryslerhad misjudged the market impact of Honda and Toyotas hybrids, but said that they had learned and are acting.
Lexus announced it will unveil the new GS 450h high-performance hybrid luxury sedan, the first rear-wheel drive hybrid ever offered, next week at the 2005 New York International Auto Show. The SULEV (Super Ultra Low Emissions) vehicle reflects the emerging trend of using hybrid powertrains to deliver high-performance balanced by fuel efficiency, rather than emphasizing fuel-efficiency balanced with performance and handling.
Emissions Control
Two of the US national laboratories were out presenting different new developments that could improve the efficiency of the catalytic reduction of NOx in vehicle exhaust.
Improving NOx reduction could bolster the use of more fuel-efficient lean-burn gasoline engines (which produce more NOx than conventional engines, and could offset the increased NOx production from biodiesel use.
Researchers at the Pacific Northwest National Laboratory (PNNL) developed a new catalysis process to reduce NOx in diesel engine emissions.
Reformer-assisted catalysis has three stages: creation of a syngas, using the syngas to create a reductant, and the subsequent catalytic reduction of NOx in emissions.
In this process, a portion of diesel fuel is passed through an on-board reformer to create a syngas. The syngas is then converted to dimethyl-ether (DME). This is a version of the same process used to synthesize DME in quantity as a clean alternative fuelit just happens on-board a heavy-duty truck and in very small amounts, rather than in a large plant next to natural gas fields.
The DME is then injected into the exhaust, enhancing the performance of certain catalysts that reduce the NOx. (a href="http://www.greencarcongress.com/2005/03/new_method_for_.html">GCC)
Work at Brookhaven National Laboratory may lead to catalytic materials that are better at cleaning up auto exhaust, and/or to more-efficient ways of generating hydrogen. The researchers used a new technique to synthesize nanoparticles of ceria (cerium oxide), and then studied how its composition, structure, and reactivity changed in response to doping with zirconium.
Adding zirconium improves cerias ability to store and release oxygen. The Brookhaven work discovered why: zirconium changes the cerias structure to increase the number of oxygen vacanciesplaces for oxygen uptake and release. Furthermore, they found that the ceria nanoparticles have much better performancehigher chemical reactivitythan the bulk form of ceria currently used in catalytic converters.
Hydrogen
Distributed Energy Systemss subsidiaries Proton Energy and Northern Power are partnering with EVermont to build a PEM electrolysis hydrogen fueling station in Vermont.
PEM Water electrolysis uses electricity, a catalyst and a proton exchange membrane (PEM) to split water into molecules of hydrogen and oxygen. PEM electrolysis is essentially the reverse of a PEM fuel cell operation, in which hydrogen is the input and water and electricity the outputs.
The system, based on a Proton Energy H Series electrolyzer, will produce up to 12 kg of hydrogen per day, using water and electricity from the grid. The hydrogen will be compressed and stored on-site and then dispensed for hydrogen-fueled vehicles.
Electricity for the project will be supplied by Burlington Electric Department, which generated 42% of its power from renewable sources in 2004, including a wind turbine located adjacent to the Public Works site.
On the vehicle side, DaimlerChrysler suggested that its first hydrogen fuel cell cars will be for sale in 2012. (GCC)
In other developments, Volkswagen announced that it will extend warranty protection for the use of B5 biodiesel (5% biodiesel) to all of its US-market diesel automobiles. (GCC)
The newly formed Zinc Energy Storage Technology (ZEST) Consortium is focusing on developing the technology and the market for zinc-based energy storage devices. The Consortium is initially focusing on the electric vehicle market in Asia, with a push for the upcoming Olympic Games in Beijing in 2008. (GCC)
