CCS: Investing in Transitional Technology is not the Same as Compromising

January 10, 2010 No comments »

I will first state for the record that I believe there is no such thing as clean coal.  I would be incredibly happy if there were no new coal fired powered plants ever built.  Even if I believed it were true, which I don’t, I would still believe that investing in Carbon Capture and Sequestration (CCS) is worthwhile.  In an ideal world, not only would no new coal fired power plants be built, existing plants would be shut down.

However, we do not live in an ideal world, and we need to do something productive until we get there.  There are still many problems with CCS, including expense and lack of storage locations large enough.  Despite the fact that renewable technologies are the best choice for new development, it will be a very long time until there will be enough production or the necessary infrastructure changes will be in place to support it.  There are so many hurdles to wide scale renewable adoption, it would be in our best interest to invest in parallel efforts to reduce the impact of current technologies, even if only temporary.

The belief of many is that coal fired power plants will continue to be a widely used energy source until the renewable alternatives are cheaper per kilowatt hour overall.  My personal belief is that it will take decades for renewable energy to be cheaper than coal on its own.  However, subsidy of renewable energy technologies, coupled with legislation requiring coal companies cover the external costs to society of burning coal, then there may be cost parity sooner.  Even if production became cheaper than coal tomorrow, the necessary changes to the grid would take years to implement, not to mention the time it would take to build the generation capacity necessary to meet current demand.

Coal has so many problems, but the sad fact is that we are stuck with it for the foreseeable future.  While CCS is only a transition technology, embracing its development is not the same thing as abandoning the belief that coal is extremely bad.  Some may say that adoption of CCS may lead to the use of coal for longer, but that’s a separate discussion.

CO2 + Bacteria + Sunlight = Fuel

December 11, 2009 No comments »

UCLA has genetically engineered bacteria to eat CO2 and turn it into isobutanol, taking energy from sun light.  Isobutanol cannot readily be used in gas tanks yet, but the process of turning CO2 directly into a hydrocarbon can be much cheaper and easier than technologies like algae or cellulose into biofuel because there are no expensive intermediate steps.

If this technology can be *cheaply* scaled to high volumes and converted to something conventional engines can use, then I would personally suspect to see it displace a lot of other biofuels.  Hopefully we’ll find out soon.

Again, Clean Coal is Anything but Clean

“Clean Coal” is still not clean.  Even when everything is scrubbed from the air, the pollutants have to go somewhere.  Pollutants from coal fired power plants usually get put in pools, which eventually leak and get into the waterway.  Repeat after me, “there is no such thing as clean coal.”

The Commerce Department has started releasing smart grid standards, but we’re still waiting for the NIST and FERC to weigh in.  They both see the importance of changes to the grid, and final comments are expected by the end of the year.

Words Used can Turn People Off of the Green Movement

Recently on a flight, I was reading the Continental Airlines magazine’s Green Edition.  I do believe Continental to be one of the greener airlines because of its efforts in biofuels (jathropa links), as well as some of the measures taken, which are outlined in some of the articles (wing tips saving fuel, meal packaging, etc).  However, I did see quite a bit of greenwashing, as well as messaging that I believe is harmful to green causes.

In more than one place in the green edition, resorts, restaurants, and other things were referred to as “tree hugging.”  I have the same complaint about TreeHugger.com, which I believe to be the best gree site on the web (if you think something is better, please post it in the comments, I’d like to read it too).  The problem with “tree hugging” and that concept was that it was used as a derrogatory term for so long.  The baby boomer generation, which is has been one of the most wasteful in history (references), interprets a tree hugger as a “dirty hippie.”

By using “tree hugger” in articles targeted to the masses, the authors alienate the readers.  Usage of the phrase immediately dissociates the reader because the message to the reader becomes something <i>they</i> are doing, not something <i>you</i> should be doing.  What makes the problem worse in the case of Continental is their default audience.  Continental’s hubs are in Newark (major New York City entry point), Houston (worst air quality and high energy sector concentration), and Cleveland (midwest rust belt and coal consumers).  While hubs are often just layovers for a lot of consumers, many professionals try to take direct flights, and when the end points are locations with industries and demographics unfriendly to the green movement, any messaging that causes the readers to further dissociate themselves is counterproductive.

What really makes this bad is the fact that baby boomers are currently in power, in both industry and politics.  Advocating green policies and practices to this demographic is difficult enough, and starting off by putting a negative image in the mind of decision makers is a bad idea.

With the target audience for sites like TreeHugger.com, the readers are already convinced of the merits of the green movement.  What we need to do is convince the ones that are actually making the decisions that can change both policy and industry investment.  The image needed to change minds is one of wise investment and the long term payoff.  Green for the sake of green alone will not convince those that have not already drank the kool-aid.

Bacteria May Help Nuclear Waste Cleanup

“The bacteria Wall is studying are bio-corrosives and can change the solubility of heavy metals. They can take uranium and convert it to uraninite, a nearly insoluble substance that will sink to the bottom of a lake or stream. Wall is looking into the bacteria’s water cleansing ability and how long the changed material would remain inert.”

If this becomes feasible on a large scale, nuclear waste cleanup may have just gotten easier.  It will be a huge step in reducing some of the drawbacks of nuclear power.  With fewer drawbacks, there should also be fewer objections, and it will become a more viable option for replacing coal as the main source of power in the US.  While this will not eliminate it completely, the bacterial processed described in the article could drastically reduce the radioactivity in an environment that either stores or is affected by nuclear waste.

Re-post: EPA Blocks Mountaintop Removal Permits

In a letter issued last week, the Environmental Protection Agency “moved toward revoking the largest mountaintop-removal permit in West Virginia history.” Citing “clear evidence” of likely damage, the EPA has asked the U.S. Army Corps of Engineers to “suspend, revoke or modify” the permit it granted in 2007 to Arch Coal to dig a 2,278-acre coal stripmine and fill six valleys and 43,000 linear feet of streams with the toxic debris.

Higher Solar Efficiency Means Reduced Cost

The headline “Solar Efficiency Record Beat” may become common, as each new record is only a small improvement over the last.  The new leader only beat the old by .3%, with 43% of sunlight converted to electricity.  For the uninitiated, solar efficiency matters because it allows for greater power output per given area of a solar panel.  While there is already high enough efficiency to power the world’s energy needs with solar, area still matters.

Area used for solar panels still matters for a few reasons.  Residential and commercial customers still have finite amounts of space to place panels.  While it would be possible for large intiatives to build solar power installations on a mass scale, progress has been slow because of high up front costs.  Higher efficiency leads to lower up front cost for a few reasons.  The first is that in most cases, higher efficiency means lower cost of materials (not always, but generally).  The second is that labor is a large percentage of installation costs, and the smaller number of panels required to produce the same output means less labor.

In many cases, home or business owners will install panels on all available area, so total labor costs will not be reduced, but cost per kilowatt goes down.  Ultimately, the cost per kilowatt hour produced is what drives adoption of a technology.  As efficiency and manufacturing processes improve, costs go down.  When solar and renewable energy become cheaper per kilowatt hour than coal, expect a huge shift in the market.
