Rentech investments in biomass gasification

leave a comment »

RentechImageA5The Los Angeles biomass technology company Rentech Inc., has completed two investment agreements with biomass gasification companies: It acquired 100 percent of SilvaGas Corporation and grabbing a 25 percent stake in ClearFuels Technology Inc.

Financial details of the moves by Rentech were not disclosed. With the acquisitions Rentech has broadened its technology portfolio and the range of its biofuel processing capability while increasing its geographic scope from Hawaii to Georgia.

Rentech, based in Los Angeles, said the agreements are “major steps forward” for its strategy of offering various options for converting urban and rural biomass feedstocks into energy products such as synthetic jet fuel, diesel fuel and electric power.

The company signed a definitive agreement to acquire Atlanta-based SilvaGas and its commercial-scale biomass gasification technology, which converts urban waste feedstocks into syngas.

Rentech also completed agreements with the Aiea, Hawaii-based ClearFuels, a bio-energy gasification and project development company. ClearFuels’ technology converts rural virgin cellulosic biomass feedstocks into syngas.

In addition to the 25 percent ownership interest in ClearFuels, Rentech said it has agreed to the installation of a ClearFuels biomass gasifier at the its Product Demonstration Unit (PDU), in Commerce City, CO. That facility is designed to produce more than 400 gallons per day of ultra-clean synthetic jet fuel, aviation fuel, ultra-low sulfur diesel, and specialty waxes and chemicals and is scalable for increased output.

The deal with ClearFuels also includes multiple licensing agreements for the Rentech Process at bio-energy facilities currently under development by ClearFuels.

With the SilvaGas acquisition, Rentech is acquiring a biomass gasification technology that has operated at commercial scale and is planned for deployment at Rentech’s Rialto Renewable Energy Center under a licensing agreement with SilvaGas. The SilvaGas gasifier can handle urban waste streams that are more varied than the virgin biomass streams that the ClearFuels gasifier has been optimized to convert, the company says.

Meanwhile, ClearFuels’ technology can convert rural virgin biomass feedstocks into syngas that is cleaner and requires less conditioning, leading to highly efficient conversion into synthetic liquid fuels, it said.

Integration of these complementary gasification technologies with Rentech’s syngas conditioning and cleanup technology will enable the company to offer integrated packages for renewable fuels and power production.

DOI kick-starts East Coast offshore wind energy development

leave a comment »


The Department of the Interior last week issued five “exploratory leases” for offshore wind energy production on the Outer Continental Shelf off of New Jersey and Delaware.

The leases are the first of this type issued by the Federal Government, which is why they are called exploratory, and not breaking wind perhaps. They were developed under an interim policy from the department and authorize data gathering activities, allowing for the construction of meteorological towers on the Outer Continental Shelf from six to 18 miles offshore to collect site-specific data on wind speed, intensity, and direction.

“New Jersey’s Outer Continental Shelf is a resource that holds a great promise for our energy independence and should be considered a haven for the clean, renewable and environmentally friendly energy that wind power provides,” said New Jersey Governor Dave Corzine. “This is a major step for the state in meeting its goal of 1000 megawatts by 2013 and 3000 megawatts by 2020,” He said.

Interior Secretary Ken Salazar issued the exploratory leases to Bluewater Wind New Jersey Energy, LLC; Fishermen’s Energy of New Jersey, LLC; Deepwater Wind, LLC; and Bluewater Wind Delaware, LLC.

Sunday sidetrack — William Gibson

leave a comment »

I’m reading Spook Country by William Gibson, one of my faves. All of his stuff is well worth exploring. A stylish writer writing about the reality we live in the cyber age. In fact I believe he coined the term ‘cyberspace’ in his early novel Neuromancer

Anyway I’m reading along in SC and there’s snippet of conversation:

“But think about blogs, how each one is actually trying to describe reality.”

“They are?’

“In theory.”


“But when you look at blogs, where you’re most likely to find the real info is in the links. It’s contextual, and not only who the blog’s linked to, but who’s linked to the blog.”

He’s perceptive and correct as usual. I have been blogging only a few months but in the blogosphere it’s more about the stacking of links and the race to pile up the most tags, rather than the content or the message. It’s as if the blog does not exist without the requisite number of links vying for attention in each post.

It makes it too easy.

EPA provides guidance to states on clean energy

leave a comment »

cleantech1The Environmental Protection Agency is providing extensive guidance to state and local environmental managers looking for the best ways to cut greenhouse gas emissions while saving money.

EPA has released what it says is a “first-of-its-kind guide” along with a load of other information, tools and resources on its website to help states adopt current best practices and available resources as they adopt clean energy programs and policies.

“States spend about 10 percent of their operating budgets on energy bills, yet these costs can be greatly reduced by implementing well-designed energy management and greenhouse gas reduction programs,” the agency said.

As an example, EPA cited New York, where a 2001 executive order directed state agencies to reduce their energy consumption by 35 percent by 2010 relative to 1990 levels. The state saved $54.4 million in energy costs through energy efficiency actions between fiscal years 2001-2002 and 2003-2004.

The agency’s 410-page “Clean Energy-Environment Guide to Action” which is part of the State Climate and Clean Energy Program, helps states identify the strategies, resources and tools best suited to their energy needs. “Each strategy has been tested and is proven to be cost effective,” EPA said.

The guide “is designed to share the experiences and lessons learned from successful state clean energy policies and to help state evaluate these options, programs and policies to determine what it most appropriate for them.”

It describes 16 clean energy policies that encompass planning, tax, grant and loan incentive structures for states, “leading by example,” energy efficiency portfolio standards, building codes for energy efficiency, state appliance efficiency standards, renewable portfolio standards, fostering green power markets and the removal of utility rate barriers to distributed generation.

Some more links to  the EPA’s clean energy programs for states and the guide’s 42-page Executive Summary.

Solar stocks: a bubble ready to burst?

with 3 comments


Another by moi that’s also currently on Triple Pundit. This one is rewritten a little and shorter.

Looking at the recent performance of solar stocks, which have been very hot, could lead to the conclusion that this bubble is ready to burst.

At the very least, J. Peter Lynch, a financial analyst and contributor to RenewableEnergyWorld.com, advises extreme caution. It’s not a market for the faint of heart.

Solar stocks have gone through a couple of surges since the late 1980s, “but we’re probably only in the second inning of a baseball game with solar stocks,” Lynch says. “At the beginning of a new market there’s more volatility, with very big moves up and down as Wall Street tries to figure out this new market. Eventually there will be a lot more companies and a lot more opportunities.”

He notes that over a span of eight weeks earlier this year solar stocks grew 72 percent or essentially two years of growth in two months. “That’s unsustainable so I’d expect a correction any time now.”

Sustainability and energy management

leave a comment »

sustainabilityEnergy management initiatives for corporations are becoming crucial factors for their sustainability efforts and the bottom line.

Energy management as a concept began as a cost-saving initiative, “but is now starting to become a strategic part of the company’s larger corporate social responsibility program,” says Aberdeen Group in a recent report, Energy Management, Driving Value in Industrial Environments.

The benchmark study of 230 executives conducted by Aberdeen research analysts Mehul Shah and Matthew Littlefield found that companies that are considered “best-in-class must do three things effectively:

–          Include energy management in corporate-wide sustainability initiatives;

–          Provide real-time as well as historical energy data to the appropriate employees that they can use as “actionable intelligence;”

–          Invest in automating energy management as much as possible to gain visibility in into the energy data while integrating it with existing technology investments.

By implementing those actions, the top rank companies can achieve a 15 percent or more reduction in energy consumption, an overall equipment effectiveness level of 90 percent and an impressive 14 percent increase in operating margins relative to corporate goals.
