Pyrolysis: the third way to biofuels

Imagine a giant pile of biomass – lets say wood chips for simplicity sake. And next to the wood chips is a big pile of money (likely from investors, whose patience for payback may vary). In a third pile is a group of job candidates: engineers, chemists & microbiologists. To get useful energy from the first pile of feedstocks requires careful consideration of all your piles. The wood chips can be burned, fermented, or –...

Harnessing Entropy

In Solar, a novel by acclaimed author Ian McEwan, the protagonist, a physicist named Michael Beard, has been tasked to evaluate submissions from the public sent to a UK panel looking for new ideas for clean energy. He divides them into piles: those that violate the first law of thermodynamics, those that violate the second law, and those that violate both. This cleantech reporter could relate. That’s why ideas that start with...

Ineos Bio – First Cellulosic Ethanol Plant in U.S.

The prize for the first company to get a commercial-scale cellulosic ethanol plant up and running in the U.S. goes to Ineos Bio. Ineos Bio is a Swiss firm, a subsidiary of the chemical company Ineos. The facility is located in Vero Beach, Fla. and has a capacity of 8 million gal of ethanol per year. It also produces 6 MW of renewable biomass power. Vero Beach is on the Eastern coast of the state (a bit more than halfway down), near...

Solar Impulse: Moving solar energy from poetry to practicality

Solar Impulse is spending the week in Washington, DC, and the C&EN headquarters is slightly abuzz with geeky giddiness. So, living a mere 15 minutes from the solar plane’s temporary home in a hangar at the Smithsonian’s Udvar-Hazy Center next to Dulles International Airport, I couldn’t resist the invitation to a Solvay-sponsored event with the pilots and crew on Tuesday evening. Melody twisted my arm kindly...

IEA Looks To Fossil Fuel Industry to Control Climate Change

Today, the International Energy Agency put out a report saying that CO2 emissions in 2012 grew by 1.4%, or 31.6 gigatonnes. This increase means that the chances of constraining emissions to cap global warming at 2 degrees C are narrowing. When I first started covering the cleantech/renewables space for C&EN back in 2008, there was a common belief among technologists and some policy makers that within a few short years, a price...

Never Mind All That: Solar on the upswing

I’m going to have to start posting more frequently. My last post was about solar firms going bankrupt in China and now my cleantech news is about how solar is set to rebound. Seems like something should have happened in between that post and this one. Actually, a few biobased chemical deals were announced. Thanks BASF and Evonik! Anyway – back to solar. Earlier this week, Lux Research (a rather skeptical gang generally)...
