Cogen beer Cleveland brewery attempts energy recyling yet is foiled by regulation	Sean Casten	15 Aug 2008	Gristmill
Last week Cleveland Scene wrote about a local brewery that is recovering its waste heat. They set out to convert the heat into electricity and useful steam for their brewery. In a great quote, the owner Patrick Conway says: 'When our engineer explained this technology to us,' says Patrick, 'it was like putting wheels on luggage.' The brewery will use the heat to run chillers, and intends also to generate electricity. But there's a catch: For the time being, however, ...

Me, on the radio in Oregon	Sean Casten	07 Aug 2008	Gristmill
Hear Bruce Silverman interview me on Portland's KBOO FM on the opportunities for waste energy recovery -- specifically in the wood products, pulp, and paper industries in the state. (Special Bonus: plug for Grist at 18:40 or so!)

The biggest low-carbon resource, by far Energy efficiency is the core climate solution, part 1	Joseph Romm	24 Jul 2008	Gristmill
Energy efficiency is the most important climate solution for several reasons: It is by far the biggest resource. It is by far the cheapest, far cheaper than the current cost of unsustainable energy, so cheap that it helps pay for the other solutions. It is by far the fastest to deploy. It is 'renewable' -- the efficiency potential never runs out. This post focuses on number one -- the tremendous size of the resource.Of the 14 or so wedges we need to deploy g ...

Biomass in Austria: An adventure in pictures The human-scale, renewable, domestic power systems reviving rural Austrian economies	David Roberts	16 Jul 2008	Gristmill
On a sunny Saturday afternoon in Salzburg, we took a field trip to a few examples of biomass in rural Austria. The country is over 40 percent forested, and over half of the forest is owned by small farmers with less than 40 hectares (just under 100 acres), so the government has put a priority on encouraging biomass use as a substitute for fossil fuels. I ...

Forbes on utility objections to combined heat and power	Sean Casten	09 Jul 2008	Gristmill
Forbes has a nice story about the historic barriers that electric utilities have thrown up to block efficient power generation. This is nothing new to those of us 'in the trenches,' but it is nice to see this topic aired from more visible podiums. It's worth the time to read for anyone who thinks that the only barrier to low-carbon generation is technological development.

A Stirling idea Development in waste-heat-to-electricity technology	Erik Hoffner	24 Jun 2008	Gristmill
Here's a 200 year old idea with merit: A Stirling engine, modified to capture the waste heat of industrial processes to make electricity. Gar noted Stirling Energy Systems' efforts in this vein to make electricity from solar thermal collectors using a Stirling engine a year ago, but instead of the sun, a startup in my neighborhood, ReGen, is developing a Stirling that will specialize in using the low to moderate heat generated by landfill gas systems, paper mills, stee ...

Nuclear deterrence Lovins and Sheikh defend their work in 'The Nuclear Illusion'	Guest author	19 Jun 2008	Gristmill
This is a guest essay from Amory B. Lovins and Imran Sheikh of the Rocky Mountain Institute. ----- David Bradish, in a post on the blog of the Nuclear Energy Institute, criticizes our methodology used to derive micropower's output in 'The Nuclear Illusion' (PDF). As Mr. Bradish notes in hypertext, our methodology is online here (PDF), and our micropower database is posted and documented here. Here's our point-by-point response to his critique: 'With the exceptio ...

A negative-carbon corn ethanol plant? Cogeneration and ethanol production	Joseph Romm	03 Jan 2008	Gristmill
I am not the biggest fan of corn ethanol. But I am the biggest fan of cogeneration, also known as combined heat and power, or CHP (well, maybe the second-biggest fan). It is probably the single most overlooked strategy for sharply cutting greenhouse-gas emissions while reducing overall energy costs. Now a new EPA report finds that running an ethanol plant on natural gas CHP can, with the right design, result in negative net CO2 emissions (click on figure to enlarge) ...

Back to the FutureGen FutureGen		18 Dec 2007	News
"clean coal" demonstration plant slated for Illinois Posted at 8:26 AM on 18 Dec 2007 FutureGen, the U.S. Department of Energy's massive "clean coal" demonstration plant, will be sited in Mattoon, Ill., officials announced this morning. Three other potential locations for the plant each lobbied heavily for the roughly $1.8 billion project to be built on their turf -- one other site in Illinois and two others in Texas. The FutureGen project, wh ...

Thomas Edison's dream: A wind generator for every house A man ahead of his times	Erik Hoffner	06 Jun 2007	Gristmill
I've always thought that Edison's notion of using DC instead of AC would've resulted in a better energy situation -- more locally produced power through cogeneration and other sources, and better storage capability. But this New York Times piece on how he worked to build an electric car, and his dream of powering every house with its own wind generator, puts him squarely ahead of his time.

Grid porn The latest on smart grids, microgrids, and nerd grids	David Roberts	29 Apr 2007	Gristmill
Three good bits from the smart grid front. First up, there's a new report out from the California Energy Commission called Distributed Generation and Cogeneration Policy Roadmap for California (PDF). Hot reading! The New Rules Project has a nice write-up on it. See also the NRP's section on barriers to distributed generation. Next up, five big companies have teamed up to create GridNet NOW, an alliance that "offers a comprehensive, cost effective suite of se ...
