Coal is somewhat notorious for not being the cleanest of fuels. Similarly all combustion systems release a good deal of carbon dioxide. A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale. (more…)

Coal is a combustible sedimentary rock that has become the world’s most used energy source. Because it is so abundant and therefore cheap, much research has been done to see what other kinds of uses it can have other than direct burning for electricity production. The liquefaction of coal (more…)

One way fossil fuel industries are trying to stay relevant in a world moving toward better, cleaner ways of producing energy is to argue that carbon emissions which contribute to climate change can be captured and stored underground. This “carbon capture and sequestration,” is supposedly a technological fix that will allow energy companies to keep burning fossil (more…)

Putting the word green and carbon together may sound like an oxymoron to most people. But researchers at Rice University in Houston, Texas, working at the new Green Carbon Center, think that instead of being a “villain in the global warming debate”, carbon could be a (more…)

In a couple of past posts I’ve criticized plans made by the South African government and World Bank to build some of the planet’s largest coal plants in South Africa—thereby dramatically increasing the country’s contribution to climate change. But give credit where (more…)

The Indian government is considering opening up densely forested areas of the country to increase supply of coal for its new thermal power plants.

The Indian government is in the process of establishing several Ultra Mega Power Projects (UMPP) which would be among the largest power generation units in the country. These power plants would operate (more…)

Each year energy-related carbon dioxide emissions account for more than 80 percent of greenhouse gas emissions in the United States. According to the Energy Information Association, that adds up to over 5,814 million metric tons (MMT) of carbon in 2008 alone. The Obama administration recognizes that this is not sustainable and that’s why we’ve actively sought to not only (more…)

William F. Stewart is the author of Climate of Uncertainty: A Balanced Look at Global Warming and Renewable Energy, from Ocean Publishing. He is co-chair of the climate change and energy practice at Cozen O’Connor.

CleanTechies had four questions about his new book.

CleanTechies:  You promise a balanced look in your title, and you give the global warming nay-sayers a chapter.  Why do you feel it’s important to take this approach?

William F. Stewart:  I know it is a cliché, but skepticism really is the lifeblood of science. Historically, it is through the intense questioning of conventional wisdom that advancement has been possible. Although there are certainly a lot of cynics and charlatans masquerading as skeptics, good faith skepticism itself must be embraced if we are to achieve new discoveries. (more…)

Tom Friedman spent most of 2009 beating the China-is-winning-the-green-race-drum, and he has started 2010 with the same focus.

In Sunday’s New York Times, the news side of the house joined their editorial page colleague, writing in a front page story that Chinese “efforts to dominate renewable energy technologies raise the prospect that the West may someday trade its dependence on oil from the Mideast for a reliance on solar panels, wind turbines and other gear manufactured in China.”

To his credit, Friedman’s push has been all about policy. He wants the United States to go all-in in a space-race-like push to match Chinese innovation in energy technology (“E.T.,” as he has glossed it). But, what has eluded his attention – and is absent again in Sunday’s news piece – is the recognition that in order to match Chinese innovation, the policy changes that would be required in the U.S. electricity markets would necessarily have to go far beyond decoupling, one of Friedman’s personal causes.

Carbon dioxide air emissions is one of the big issues in global warming debate. However, before you start controlling by putting the carbon in the ground, you first have to put lawyers in a room to argue. After a year that saw billions of dollars spent around a variety of carbon capture and storage pilot projects, the focus in 2010 will shift from press conferences and engineering discussion to court cases and conference tables.

Everyone has an opinion on what is the right thing to do in global warming. Far from just an engineering decision the task of making technology an effective weapon in the fight against climate change will take a lot more than working out funding details and letting the engineers work.
