Counting and measuring carbon, although a daunting and remarkably puzzling undertaking, is a fundamental skill an increasing number of people will need to garner in the effort to understand and mitigate the effect of greenhouse gases and global warming. Especially so, since the world population continues growing by quantum measures and all of those folks are going to need survival basics such as heat and refrigeration, plus multitudes of electrical extras, such as mobile phone and computer power, broadband Internet capacity, etc.

We applaud the development of alternative energies but add this caveat for all supporters: it will be an extraordinary feat if the percentage of alternative energy powering the world’s grid comes anywere close to reaching five percent of supply in the next 20 years.

That brings us to the subject of power plants. Here are some power plant facts, according to the PowerPlantCCS website: 

“There are over 50,000 power plants in the world. These power plants constitute the single largest emitting industry for CO₂ emissions.” Read more of this >>

I have not met Barry Cohen, executive director of the National Algae Association, based in Woodlands, Texas, nor discussed with him any of the challenges facing his nascent industry. But the challenge he made to his membership caught my attention:

“I am issuing a challenge for the year 2010: Build out a 100 acre turnkey algae production facility (growing, harvesting and extraction) without any local, state or federal grant funds.”

Mr. Cohen’s greeting to all for the beginning of 2010 is well worth reading, especially by all who want to see alternative fuels gain more solid footing on the American (and world) energy charts.

The accounting of his challenge ias worth the read:

“When this (American oil production) all started in 1859, nobody had all of the answers. 150 years later, the oil industry is still looking for answers. A 100 acre turn-key commercial-scale algae production facility will allow algae producers to look at real commercial algae production and operations as well as economies of scale issues. It will give algae researchers a much better understanding of commercial-scale algae production issues to work on as opposed to small raceway ponds and desk-top lab photobioreactors. It is, at this point, useless to continue to fund algae research without seriously funding commercial-scale algae production farms. As some have already learned, intellectual properties have no practical use if there is not an industry to use them. In order to create any value in existing algae technologies, we must have commercial-scale algae production facilities that can use them!

“Commercial-scale algae production is key to our industry and is one solution that helps to reduce dependence on foreign oil, to create new jobs and reduce CO2 emissions. The NAA challenges the algae industry to build a 100 acre commercial-scale algae production plant without any local, state or federal grants – this will be the true test of algae production farming and algaepreneurism at its finest!

“I would like to see the first 50 acres of production with proven benchmarked results – totally designed, developed and put into production without a single dollar of government money. The next 50 acres can be improved by making minor changes based on what was learned from the first 50 acres. I know it can be done, and you know it can be done – it´s time to do it!”

For those wanting more information on algae and its low-carbon potential as an alternative fuel source, take a visit to Oilgae , a blog focused on this subject.

Some might even want information on how to grow their own. Below are clips from today’s post:

“Cultivation of Algae in Photobioreactor”

“Algae can also be grown in a photobioreactor (PBR). A PBR is a bioreactor which incorporates some type of light source. Virtually any translucent container could be called a PBR, however the term is more commonly used to define a closed system, as opposed to an open tank or pond.

A world turning with low carbon energy is no small feat, even if everybody wants such a clean place. Poised before the open of the the summit at Copenhagen, there is no better time than now to equip oneself with the correct information in setting goals to switch to low-carbon energies. Implementing change for world climate issues, no matter how good it might be for all, is an action requiring an extraordinary amount of time, infrastructure, and will.

In the December 3 issue of Nature, Gert Jan Kramer and Martin Haigh point to this reality in their article, “No quick switch to low-carbon energy.”

In the first of two pieces on reducing greenhouse-gas emissions, the two writers analyze historic growth in energy systems in explaining why deploying alternative technologies will be a long haul that could span multiple decades.

Below is a summary of their content, plus highlights of facts all should consider.

* There are physical limits to the rate at which new technologies can be deployed * Governments need to design policies targeted at specific technologies to accelerate deployment
* More action is required on demand side to increase efficiency and curtail consumption.”
“To combat climate change, the world’s entire energy system needs a major overhaul before the middle of the century. But can we build new energy supplies that quickly? …… Because the scale of the energy system is so huge, it takes time to build the human and industrial capacity to achieve substantial deployment.” Read more of this >>

Stalk Market is based in Portland, Oregon

Some packaging companies make one feel much better about our “throw-away” side — StalkMarket Products, for instance. In September, this Oregon-based producer of compostable food service products, became the first company in the North American packaging industry to gain Carbon Trust Certification for the carbon footprint of its sugar cane plates and bowls.

Presently StalkMarket is one of a few U.S. based companies to gain this certification. The Carbon Trust was set up in 2001 by the UK government as an independent company , with a mission to accelerate the move to a low carbon economy. Read more of this >>

These notes come from the World Bank Press Review on rising CO2 emissions coming from 40 industrialized countries:

“Carbon emissions by industrialized nations increased one percent in 2007, a ‘worrying’ rise ahead of a crunch climate summit in Copenhagen in December, the UN climate agency said Wednesday. Emissions in 2007 by 40 industrialized countries with reporting obligations under the UN Framework Convention on Climate Change (UNFCCC) were around four percent below 1990 levels, the UN Climate Change Secretariat (UNCCS) said….” [Agence France Presse/Factiva]

AP adds that “…EU countries did cut their emissions year-to-year, by an average of 1.6 percent, led by Denmark’s 6.1 percent reduction. But the US, the biggest emitter in this group, increased its emissions by 1.4 percent, and the output of heat-trapping gases by Japan, Canada and Australia also rose, the data show….” [Associated Press/Factiva]

Greenwire reports that “…emissions in 2007…were around 4 percent below 1990 levels, the secretariat said. However, from 2000 to 2007, emissions rose 3 percent….Much of the decrease in CO2 emissions from 1990 levels is due to the economic decline of countries in Central and Eastern Europe after the fall of communism….” [Greenwire (US)/Factiva]

Even at the risk of preaching, it is critical for all to comprehend what is happening with carbon on this planet and learn how we might better manage output. GRM

The following clips come from  Matt Cawood, writing on a study from the Wentworth Group of Concerned Scientists at farmonline:

“Agricultural land could be the focus of an “economic opportunity of unparalleled scale”, according to the Wentworth Group of Concerned Scientists, which has called for a re-write of emissions trading legislation to properly recognise “terrestrial carbon”.

“In a discussion paper released earlier this week, the Group argues that by focusing on terrestrial carbon sequestration as a solution to climate change, Australia can simultaneously address many of its most pressing environmental challenges.

“Terrestrial carbon includes carbon stored in forests, woodlands, swamps, grasslands, farmland, soils, and derivatives like biochar and biofuels.

“We’re about to create a multibillion dollar terrestrial carbon market, and that has the potential to radically change our rural landscapes,” said Wentworth Group director Peter Cosier. “We have to maximise the benefits and minimise the consequences.”

News on the fourth annual Solar Decathlon from Environmental News Service . (NOTE: previous link does not work; use DOE site. ) I would love to be there and see the many solutions.

from Environmental News Network: “More than 800 students in 20 teams from the United States, Canada, Spain and Germany will compete all week in ten contests that evaluate the architecture, engineering, comfort, marketability, appliances and lighting of the solar houses. The teams will perform everyday tasks, such as cooking, laundry, and washing dishes, to test the energy efficiency of their homes.”

After developing a promising technology to recycle carbon dioxide (CO2) into gasoline, Santa Barbara, CA – based Carbon Sciences, Inc. has announced developing key enzymes that will accelerate its biocatalytic process and significantly lower the cost of fuel production.

One potential large supplier of such captured CO2 might be coal-fired electrical power generating plants.  The impact could be  significant, said Carbon Sciences CEO, Byron Elton. “We strongly believe we are developing the most efficient and viable renewable fuel technology in the world. We estimate tat that with less than half of the the CO2 emissions from coal-fired power plants, we can produce 30 percent of the world’s fuel supply.”
