Most people are familiar with automobile air emissions. Perhaps one day there will only be electric cars and no car air emissions. But there are many on other engines in use by commercial and industrial operations that may cause air emissions. In general these are called reciprocating internal combustion engines, or RICE.

On February 17, the Environmental Protection Agency issued a final rule that will further reduce emissions of toxic air pollutants from existing diesel powered stationary reciprocating internal combustion engines.

More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system.

Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas of shortages.

The U.S. electricity grid today resembles the roads and highways of the mid-twentieth century before the interstate highway system was built. What is needed today is the electricity equivalent of the interstate highway system.

The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?

On a placid bend of the Ohio River in West Virginia sit two coal-fired power plants. The Philip Sporn Plant boasts four boilers from the 1950s, surrounded by mountains of coal and a series of man-made lakes to contain the toxic residue of its coal-burning.

A faint haze emanates from its main smokestack, the only visible sign of the thousands of tons of acid-rain-forming sulfur dioxide, smog-forming nitrogen oxides, and climate-warming carbon dioxide it emits each day, a consequence of the plant’s complete lack of pollution-control technologies. The 1,100 megawatts of electricity it produces will never benefit from such controls, as they are too expensive to install on the multiple small boilers, according to the plant’s owner, American Electric Power.

Scientists at Imperial College London report that they have invented a polymer, made from non-food sources, that could be used in packaging and then tossed into compost piles or landfills, where it degrades upon contact with water.

The scientists said they worked three and a half years on a biodegradable polymer that is made from sugars known as lignocellulosic biomass, derived from fast-growing trees, grasses, and agricultural and food wastes.

Lead researcher Charlotte Williams said the team accomplished its goal of producing the polymer from non-food sources and using small amounts of water in the process — an advantage over another biorenewable plastic, polylactide, whose manufacture requires large amounts of water and energy.

Terra Venture Partners, a Jerusalem-based venture capital fund focused on seed and early-stage cleantech investments, was recently named Israel’s most active venture capital investor for 2009.

According to the IVC Research Center, Terra Venture Partners made six first investments in 2009, followed closely by Carmel Ventures, Giza Venture Capital, Jerusalem Venture Partners, Magma Venture Partners, Pitango Venture Capital, Sequoia Capital, which each made five first investments in 2009.

CleanTechies is fortunate to have some of the sharpest minds in the energy and clean tech industries as regular readers, but even if you don’t have a Ph.D., you should be able to answer this quick math quiz: “Which price tag is cheaper, $8 billion or free?”

Don’t hurt yourselves!

On Tuesday, President Obama officially announced $8 billion in government loan guarantees for construction of two new nuclear plants in Georgia, the country’s first expansion of nukes in more than 30 years.

A day later, the Vermont state legislature officially began deliberations on the question of relicensure of Entergy’s Vermont Yankee nuclear plant. While there are some transaction costs associated with keeping Vermont Yankee open past 2012, the cost is nowhere near $4 billion.

Given the commitment the president made to clean, domestic nuclear power just 24 hours earlier, you would expect the White House to jump right in on the question of relicensure in Vermont, right? Not so fast. (more…)

A study by scientists from the U.S. National Climatic Data Center refutes claims from climate change skeptics that data from U.S. weather stations was seriously flawed and exaggerated the rate of temperature increases.

The study, published in the Journal of Geophysical Research, says that U.S. weather stations may have actually slightly underestimated temperature increases.

Anthony Watts, a former meteorologist who publishes the WattsUpWithThat blog, compiled photo evidence of what he considered poorly-located weather stations across the United States, including locations that could be influenced by artificial heat, such as those near parking lots and air conditioning systems.

The E.U. Emissions Trading System  (ETS) has given a sense of urgency to the development of renewable aviation jet fuel. British Airways is the latest airline to ink a deal, announcing that they are building capacity to produce renewable aviation biofuels using waste biomass as a feedstock.

British Airways has partnered with the U.S. company Solena Group to establish Europe’s first sustainable jet-fuel plant and plans to use the low-carbon fuel to power part of its fleet starting in 2014.

We can’t successfully tackle climate change without changes to the corporate regime which has been in place in America since the Reagan presidency. That’s the underlying message of Charles Derber in his latest book, Greed to Green: Solving Climate Change and Remaking the Economy. It’s a message he delivers with directness in a book much more readable than I expected from an academic sociologist.

He accepts the position of scientists like James Hansen and others who point to the ominous dangers of tipping points in climate and conclude that we are already above a safe level of atmospheric carbon dioxide, which they consider no more than 350 parts per million. It’s not a happy acceptance. “No sane person would wish it to be the scientific truth,” he writes.

Derber recounts the terrible difficulty he had, after realising with despair the seriousness of climate change, in dealing emotionally with the prospect of mass, collective death — “more difficult than dealing with my own personal death.”

The only good news he discerns is that the scientific truth may be spreading and leading to a tipping point in the world’s social and political awareness. (more…)

In a recent study conducted by researchers at the University of Virginia and published in Environmental Science & Technology, the authors claim that algae causes more harm to the environment than traditional biofuel crops like corn.

However, in this study, the researchers used algae production data from at least a decade ago.

In response, Andres Clarens the lead author of the study said he used the most recent data that he could, which was about 10 years old. Algae biofuel companies keep their research a closely guarded secret, he said.
