Major Coal-to-Liquid Project in China


Financial Times. Sasol, the world’s largest synthetic fuels producer, is building two coal-to-liquid plants in China. (Image at right sketches the production process. Click to enlarge.)

The two projects, in the Ning Xia and Shaan Xi provinces, are expected to cost about $3bn each and to have a combined annual production of 60m tonnes of oil. China currently needs to import 100m tonnes of oil a year and is keen to reduce its reliance on the Middle East.

“It is a very big deal,” a company executive said yesterday. “We are talking four or five Secundas.” Secunda is Sasol’s flagship plant in South Africa, which produces 150,000 barrels of oil a day.

The project had been rumored for some time, with lengthy discussions between the parties concerning protection of Sasol’s intellectual property.

China’s Energy Development Program

Xinhuanet. China’s cabinet approved in principle the draft of China’s medium- and long-term energy development program, covering the period from 2004 to 2020.

  • Make energy conservation the top priority.

  • Adjust and optimize the energy structure. Pursue an energy development strategy with coal forming the mainstay and electricity the center of the energy structure, while promoting comprehensive development of oil, gas and new forms of energy.

  • Fully tap both domestic and overseas resources and markets. While making domestic energy exploration, exploitation and construction projects as the basis, China should also actively participate in energy resource cooperation [and competition] and development projects around the world.

  • Rely on scientific and technological advance and innovation.

  • Enhance environmental protection and strive to reduce the impact of energy production and consumption on the environment.

  • Attach a high degree of importance to energy security. Energy supply should be diversified, construction of oil reserves should be accelerated and the energy security pre-warning and rapid response mechanism should be improved.

  • Institute safeguard measures for energy development. Policies regarding energy resources and energy development should be improved, the market mechanism should be brought into full play and input in energy issues should be increased.

We can already see aspects of this being carried out in China’s decisive and expansionary moves in the global oil market and in its seeking to leverage its enormous coal resources.

To that point, Sasol has announced that it is building two $3 billion coal-to-liquid plants in China to feed the country’s demand for fuel without increasing reliance on external sources of oil—such as the Middle East. Separate post on this coming.

O2Diesel Shifts to Amex

O2Diesel, an e-diesel provider, is shifting tomorrow to the American Stock Exchange from being an Over The Counter bulletin board stock. Upgrading its profile, in other words.

Alan Rae, President and CEO of O2Diesel Corp., said, “Our move to the Amex is a significant step in the Company’s evolution from a development-stage company to one focused on the full commercialization of our clean-burning diesel fuel technology throughout the U.S., Brazil and other key global markets. As we move forward, our commercialization strategy will include leveraging key partnerships with industry leaders for marketing, distribution and manufacturing of our O2Diesel™ product for use by centrally fueled vehicle fleets such as truck and bus fleet operators, as well as the U.S. military, construction equipment and railroads.

“Our listing on the Amex will help increase our visibility in the U.S. investment community, and we look forward to building broad awareness of the O2Diesel investment story among fund managers and analysts as we begin to execute on our strategic goals.”

The move reflects the growing business awareness around ethanol as a fuel and as an additive.

E-diesel refers to a blend of standard #2 Diesel (petroleum-based) with up to 15% ethanol and up to 5% special additives. The special additives are necessary to overcome issues with solubility(ethanol has limited solubility in diesel), cetane number (standard ethanol has a cetane number of 8, diesel of 42-50), and lubricity issues. More on this from the National Renewable Energy Laboratory here. E-diesel has to be handled more like gasoline than standard diesel -- it has a lower flashpoint, for example.

EPA Helps India With Climate Change

Newkerala.com. The US Environmental Protection Agency (EPA) has launched a $500,000 effort to help control pollution in India, the US embassy said in a statement here Tuesday. Releasing a report on air pollution in India, the EPA urged India’s environmentalists to take advantage of its initiative, Integrated Environment Strategies (IES).

“This is part of a larger US-India partnership to mitigate the effects of climate change,” the statement said.

The report stresses the need for improved transportation and the use of alternative fuels like natural gas, since the air here shows high levels of airborne particles from vehicles and industries.

Hmm. Sounds like we should stress the same things here.

We’re in Deep...Soot


Associated Press. U.S. counties that are home to nearly 100 million people appear to flunk federal air standards because of microscopic soot from diesel-burning trucks, power plants and other sources, the Environmental Protection Agency said Tuesday. [The soot referred to is called PM2.5 -- particulate matter less than 2.5 micrometers in diameter -- less than one-seventh the width of a human hair.]

The EPA said a preliminary analysis showed that 243 counties in 22 states -- almost all in the eastern third of the nation and in California -- may have to take additional measures to curb pollution to meet the standards by 2010. [EPA’s map of non-attainment on the right shows states that pass in green, states that flunk in sooty gray.] The largest concentrations of counties in noncompliance were along the urban corridor from New York City to Washington, D.C., eastern Tennessee, in the Ohio River Valley region and counties surrounding the urban centers of Pittsburgh, Cleveland, Detroit, Chicago, St. Louis and Atlanta.

The Los Angeles Basin and interior central California also face significant soot air quality problems as does a small corner of northwestern Montana -- one of the few strictly rural areas cited by the EPA. Leavitt said the county had dirty air because of pollution from mining activities near Libby, Mont.

The EPA designations went well beyond a list of counties that states submitted to the agency in May. The governors listed 141 counties with a population of 79 million people as in noncompliance. The EPA added another 102 counties.


More information on the PM2.5 designations are here on the EPA site. Also here is a more detailed, county-by-county PDF map showing the counties the states thought were in non-attainment, and the additions the EPA made. Thumbnail image to the right.

Correcting this will be expensive.

Lexus Plans 3x Euro Sales, Leads with Diesels and Hybrid

Financial Times. Lexus is planning to triple its sales in Europe over the next six years.

Takis Athanasopoulos, chief operating officer of Toyota Motor Europe, said the brand’s first diesel engines and a hybrid petrol-electric off-roader would help boost sales to more than 60,000 by 2010 and bring the brand into profit. Last year it sold 21,651 vehicles in Europe, and Mr Athanasopoulos said it was running at break-even.

“Europe is the cradle of the premium market,” said Mr Athanasopoulos at the Automotive News conference in Switzerland. “But we are operating in less than 50 per cent of the market because we have no diesel engine, and diesel engines make up more than half of premium sales.”

Lexus will introduce its first diesel-powered car next year, as well as the RX400H hybrid off-roader, which it hopes will be the first environmentally sensitive 4x4 in Europe.

By comparison, Lexus sold 26,155 vehicles (passenger cars and SUVs) in the US in May. Be interesting to see if Lexus will bring the diesel to the US as well, and how it would do against the Mercedes.

Tackling Diesel Startup and Emissions With Electronic Control

beru_psgBeru AG, a leader in diesel cold-start technology, has rolled out a new Instant Startup System (ISS) plus a smart pressure sensor glow plug (PSG) that can play a critical role in minimizing diesel emissions at startup and during all phases of operation. (The image at right is a cross-section of the PSG. Click to enlarge.)

While gasoline engines use a spark plug to ignite the air/fuel mixture, diesel engines rely on the heat of compressed air to ignite a precise amount of fuel to initiate combustion. Heating the air to a minimum starting temperature of 850°C is critical for diesel engine start-up.

In low temperatures, cold intake air and cold cylinder walls hinder attaining the necessary starting temperature. Glow plugs have functioned as an additional heat source at startup to raise the temperature of the intake air to the point necessary to initiate combustion.

Beru’s new Instant Start System can uses optimized glow plugs and an electronic controller that can individually regulate the glow time and voltage for each individual glow plug at any time during operation -- not just at startup.

Operating in conjunction with the control unit of an electronically managed engine, [ISS] aims to ensure optimum combustion conditions during the phases which continue to recur while an engine is operating normally and lead to an increase in the concentration of exhaust pollutants.

Such phases include idling or after extended periods of overrun. At the same time the ISS device targets petrol-style key start, i.e. starting without preheating at temperatures as low 32 degrees F and with only two seconds of glow plug operation at -77 degrees F. Automotive Industries.

The addition of the Pressure Sensor Glow Plug (PSG) to the Startup System provides an even greater deal of intelligent control of combustion. Beru’s goal is to provide control akin to that required in an HCCI engine, with the resulting drop in emissions.

Temperature Up, Rice Yield Down

Research reported in the current issue of the Proceedings of the National Academy of Sciences (PNAS) found a direct correlation between rising temperatures and a decrease in rice crop yield.

Here we report that annual mean maximum and minimum temperatures have increased by 0.35°C and 1.13°C, respectively, for the period 1979–2003 and a close linkage between rice grain yield and mean minimum temperature during the dry cropping season (January to April). Grain yield declined by 10% for each 1°C increase in growing-season minimum temperature [i.e., nighttime temperature] in the dry season, whereas the effect of maximum temperature on crop yield was insignificant. This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming.

This study confirmed what had been predicted by simulations -- that global warming reduces crop yield. Unfortunately, this study also revealed that the simulated reductions were smaller than the data actually shows. Global warming has a more devastating affect -- at least on this particular staple -- than previously thought.

Again we find a situation of increasing demand matched with declining yield. Just to keep pace with population growth for which rice is a staple, global production needs to increase at approximately 1% per year. Given what this research highlights, that will be a difficult target to hit.

Mitigating the effect of greenhouse gases and global warming is a long-term process. Once the gas is in the atmosphere, it stays there for a long time. We must take action now, though, to decrease the acceleration of the problem, and to minimize the scale of the long-term impact. Much of the potential (both positive and negative) lies in the transportation sector.

It is very worthwhile reading the paper -- Rice yields decline with higher night temperature from global warming -- at the link above.

Oil Majors Differ on Same Reserve

Reuters. The oil and gas reserves controversy sparked by Royal Dutch/Shell’s shock January downgrade took a new turn on Tuesday as two of Shell’s partners in a Norwegian gas field differed over reserves bookings.

In its filing, Britain’s BP reaffirmed its bookings for the Ormen Lange gas field, Norway’s biggest offshore development. However, Norwegian company Norsk Hydro cut its bookings for the same field by about a third. Ormen Lange was the focus of one of Shell’s well-publicized reserve cuts this year.

Resolving this is going to require a more rigorous set of definitions from the SEC on what can be considered a bookable reserve. It continues to highlight the uncertainty around reserve numbers which then ultimately end up being the basis for policy decisions. (In other words, it makes a big difference if production peaks in 5 years or 50.)

It’s a bit like trying to avoid hitting a mountain in an airplane when the altimeter readings are open to interpretation. You may be lucky and get it right -- but you may not.

GM Yeast for Commercial Ethanol Production

Iogen Corporation (earlier post) has has obtained the first (and non-exclusive license) from the Purdue Research Foundation for a genetically modified yeast that can produce ethanol from agricultural waste.

Purdue’s genetically altered yeast allows about 40 percent more ethanol to be made from sugars derived from agricultural residues, such as corn stalks and wheat straw, compared with “wild-type” yeasts that occur in nature.

The agricultural residues are primarily made up of cellulose and “hemicellulose,” which are known as cellulosic materials. Unlike traditional ethanol feedstocks, such as corn kernels, the cellulosic materials contain two major sugars, glucose and xylose, which cannot both be fermented into ethanol by natural Saccharomyces yeast, the microorganism used by industry to produce ethanol, said Nancy Ho, a senior research scientist and leader of the molecular genetics group in Purdue's Laboratory of Renewable Resources Engineering, or LORRE.

The Purdue researchers altered the genetic structure of the yeast so that it now contains three additional genes that make it possible to simultaneously convert glucose and xylose to ethanol. The ability to ferment xylose increases the yield of ethanol from straw by about 40 percent. Being able to simultaneously ferment glucose and xylose is important because both sugars are found together in agricultural residues, Ho said.

The original paper describing the yeast:“Genetically Engineered Saccharomyces Yeast Capable of Effective Cofermentation of Glucose and Xylose”, Applied Environmental Microbiology, May 1998, p. 1852-1859, Vol. 64, No. 5.
