California's electricity - Phasing out coal

In its headlong rush to take the front line in the fight against Global Warming (California's AB32) the California Energy Commission has approved regulations that limit the purchase of electricity from power plants that fail to meet strict greenhouse gas emissions standards. That has to be considered bad news for neighboring states which have built coal plant facilities specifically to service the insatiable electricity demands of Californians. According to the Los Angeles Times, 47% of the electricity purchased by the Los Angeles Department of Water and Power comes from giant coal-fired plants in Arizona and Utah.

The benchmark number that new contracts must meet is 1,100 pounds of carbon dioxide (CO2) per megawatt hour. A 2000 study by the U.S. Department of Energy, Carbon Dioxide Emissions from the Generation of Electric Power in the United States, shows that the standard means electricity coming from plants that are cleaner than the average natural gas plants of 1999 (1,321 versus coal's whopping average of 2,095 pounds of CO2 per megawatt hour).

There is no discrimination between carbon positive (fossil fuels) vs. carbon neutral sources of energy. There should be because co-firing carbon neutral biostock could ease the blow to existing coal plant operations.

It is important to note that California periodically suffers brown-outs during the summer months and was the victim of the deregulation electricity nightmare of 2000 and 2001. As Wikipedia recounts the tail:

The California electricity crisis (also known as the Western Energy Crisis) of 2000 and 2001 resulted from the gaming of a partially deregulated California energy system by energy companies such as Enron and Reliant Energy. The energy crisis was characterized by a combination of extremely high prices and rolling blackouts. Price instability and spikes lasted from May 2000 to September 2001. Rolling blackouts began in June 2000 and recurred several times in the following 12 months.

That is not to suggest that current legislation is a "result of gaming". However, it is important that compensating power generators be contracted relatively quickly with a clearcut guarantees that the current benchmark does not suffer downward creep that would raise the risks for investors. As we learned in 2001, it is the public that will suffer the possible consequences and pay the ultimate tab of mis-steps of our energy decisionmakers.

Here is a reprint of the press release made May 23, 2007 by the California Energy Commission...

New Regulations Restrict Purchase of Electricity From Power Plants That Exceed Greenhouse Gas Emission Limits
New Performance Standard to Regulate Power Plants

The California Energy Commission today approved regulations that limit the purchase of electricity from power plants that fail to meet strict greenhouse gas emissions standards. New regulations, as part of SB 1368 (Perata), prohibit the state's publicly owned utilities from entering into long-term financial commitments with plants that exceed 1,100 pounds of carbon dioxide (CO2) per megawatt hour.

"Working with the Legislature, the Governor has demonstrated a clear vision with this first-in-the-nation legislation to reduce emissions," said Energy Commission Chairman Jackalyne Pfannenstiel. "His bold leadership is helping to reduce California's carbon footprint by ensuring a clean supply of electricity," continued Pfannenstiel.

The implementation of SB 1368 is part of the Energy Commission's further implementation of AB 32 (Nunez), a landmark bill signed by Governor Arnold Schwarzenegger that calls for California to reduce emissions of carbon dioxide and other gases by 25 percent by 2020.

To reduce greenhouse gas emissions, SB 1368 directed the Energy Commission, in collaboration with the California Public Utilities Commission (CPUC) and the California Air Resources Board, to establish a greenhouse gas emission performance standard for power plants.

This standard was reached by evaluating existing combined-cycle natural gas baseload power plants across the west and is the same CO2 measurement approved by the CPUC.

Created by the Legislature in 1974, the California Energy Commission is the state's primary energy policy and planning agency. The Energy Commission has five major responsibilities: forecasting future energy needs and keeping historical energy data; licensing thermal power plants 50 megawatts or larger; promoting energy efficiency through appliance and building standards; developing energy technologies and supporting renewable energy; and planning for and directing state response to energy emergency.

Tying Energy Efficiency to Renewable Energy

The American Council on Renewable Energy (ACORE) has teamed up with the American Council for an Energy-Efficency Economy (ACE3) to make a statement that creating new renewable energy technologies (RE) will not be enough to achieve national and international goals to meet energy demands while reducing our dependence on carbon positive fossil fuel systems. We also have a responsibility to develop energy efficiency (EE) standards and advanced technologies to mitigate the demand for energy and reduce carbon emissions.

This report, while limiting its scope to renewable electricity, does a good job of not only describing the synergies possible between RE and EE, but also provides numerous case studies of progressive state policies, public benefit funding, and corporations who have demonstrated how these synergies can be implemented.

Below are the conclusions of the report. The full report is available for download from the ACEEE website.

ENERGY EFFICIENCY INVESTMENTS AND RENEWABLE ENERGY PURCHASES TOGETHER ARE "TWIN PILLARS" IN REDUCING CARBON EMISSIONS
Bill Prindle and Maggie Eldridge,
American Council for an Energy-Efficient Economy
Mike Eckhardt and Alyssa Frederick,
American Council on Renewable Energy

Energy efficiency and renewable energy are the cornerstones of sustainable energy policy. Demand growth for energy must be brought into a sustainable range, so that clean renewable energy technologies can begin to “catch up” with energy demand. If energy demand grows too fast, no supply technology, no matter how clean, will be able to substantially reduce fossil fuel consumption.

Energy efficiency and renewables thus must go hand in hand in any clean energy future. Fortunately, pursuing them jointly offers several important synergies over pursuing one to the exclusion of the other, such as:

• Lower total energy cost—A combined efficiency/renewables resource portfolio is typically less expensive than a renewables-only portfolio, and also generates greater total resource impacts;

• Better timing—Efficiency can typically be deployed quickly, achieving important impacts in the near and mid terms; renewables can take longer to deploy, but may ultimately deliver larger resource impacts;

• Electricity price stability—Efficiency and renewables provide complementary price hedges in power markets, by both moderating demand and diversifying fuel sources;

• Electric system reliability—Energy efficiency can reduce peak demand, reducing the risk of blackouts, while renewables diversify generation sources, and both efficiency and renewables can provide locational benefits in the form of distributed generation; and

• Regional resource balance—While renewables’ availability varies from region to region, energy efficiency is consistently available in end-use sectors across the country. Pursuing both efficiency and renewable resources in tandem thus makes it easier to attain national energy resource targets in any given state.

Woody Biomass - Energizing a new generation

America is witnessing the balkanization of its renewable energy portfolio. The sun belt is home to solar energy. The corn belt is home to ethanol. Landfill bioenergy is focused in urban areas. The nation's woodpiles are in the Pacific Northwest and the Southeast. Each region will have to come to grips with the economic, technical, environmental, and cultural changes that will be necessary build, market, and sustain development in their communities. NIMBY-ism will be a constant, frustrating impediment to many grand schemes.

We have seen the impact that ethanol has played in the cornbelt. Its communities have embraced the technologies - not without some consternation from its livestock industry. Individual farmers have banded together to form cooperatives to build ethanol plants. Agricultural giants like ADM and Cargill are re-evaluating how they can realign their business units to capitalize on their waste and biomass assets. Politicians are displaying uncharacteristic bipartisanship on ag/energy issues.

Following this model, we are now witnessing an emerging focus in the southeastern U.S. - home to communities that are committed now and in future generations to forestry and wood-related companies. 44% of the existing renewable energy generated in the U.S. comes from and is used by this industry - mostly generated from woody waste accumulating at paper and pulp mills. Landowners are eying biorefinery plans for the region to see if it makes sense to form cooperatives. Moribund mills and chemical factories that have lost business to foreign competition are now viewed as possible sites for new bioenergy ventures since they already have supply and distribution infrastructure in place.

The best resource of the region is the character of the indigenous citizens. Unfailingly patriotic but often regarded as the underappreciated step-children of America, many communities of the Southeast are eager to finally have an opportunity to contribute their regional ingenuity, brawn, and industrial capacity to the national effort to end American addiction to foreign oil. It is, after all, the young, proud southern recruit that continues to carry the bulk of the national security burden caused by this addiction.

As a political footnote, presidential aspirants interested in a Southern strategy should remember that in 2000 Gore lost ALL the states in the region - including his home state of Tennessee which would have put him in the White House. A commitment to woody bioenergy development of the region would be well received. It is not clear that the same can be said of the Pacific Northwest.

BIOoutput 101: The BioTown Sourcebook

For anyone who desires a simple introduction to the current range of potential BIOoutput products, I suggest a careful reading of a brief technical overview document called The BioTown, USA Sourcebook of Biomass Energy (released in April, 2006). It was written for the Indiana State Department of Agriculture by scientist and fellow blogger, Mark Jenner, PhD. who has his own website called Biomass Rules.

Below you can see an overview graphic that charts where bioconversion products (highlighted in blue) fall in proper context for addressing BIOstock, BIOconversion, and BIOwaste issues. For this reason, I offer a similar 101 abstract treatment in each of my BlogRing blogs.

This BioTown sourcebook is the official inventory on local energy use, available biomass fuels and emerging technologies for Reynolds, Indiana. As such, it can serve as an inventory template for any similarly focused study of a medium-sized rural community. It greater importance is its microcosmic view of rural communities as decentralized, sustainable entities that possess more than enough biomass to service their own energy needs.

Part of the report is devoted to an accounting of the existing energy demand in BioTown: transportation fuels, electricity, and natural gas. As the author states:

The bottom line is that as the cost of fossil fuel-derived energy continues to roughly double every five years, the value of biomass energy makes excellent economic sense. Agricultural commodity prices have remained competitively low for decades. Historically, if the supply of corn, beans, or even hogs is below demand, more are grown the next year – keeping commodity prices low.

At right is a broad "list of product categories from the Guidelines for Designating Biobased Products for Federal Procurement" drafted in 2003 (click to enlarge). "This federal rule-making process was part of a federal policy to procure supplies that made from bio-based material and meet specific criteria." Those criteria are spelled out as percentages of minimum biobased content necessary to qualify. It demonstrates the incredibly broad range of applications the output of bioconversion processes can be applied to.

This report is not a utopian call to return to rural, communal living. It is, instead, an affirmation that there are many biomass resources available and technologies in development to provide environmentally clean bioenergy alternatives to the existing fossil fuel energy paradigm. Rural communities can develop expertise and marketable output best suited to their own resources and industries. Urban communities can develop some technologies that are relevant to the diversion of trash from landfills.

The BioTown, USA Sourcebook of Biomass Energy

BioTown, USA is Indiana Governor, Mitch Daniel’s, bold approach to develop local renewable energy production, create a cleaner environment, find new solutions to municipal/animal waste issues, and develop new markets for Indiana products – all at the same time. BioTown, USA is quite simply the conversion of Reynolds, Indiana from a reliance on fossil fuels to biomass-based fuels. With the implementation of BioTown, USA, a template will be set that simultaneously promotes Indiana energy security, rural development, profitable agriculture and a green, thriving natural resource environment.

The only conclusion that can be made is that BioTown, USA is profoundly thermodynamically and technologically viable. Reynolds, Indiana used 227,710 million BTUs (MMBTU) in 2005. White County annually produces over 16,881,613 MMBTU in undeveloped biomass energy resources. That is 74 times more energy than Reynolds consumed in 2005.

BioTown, USA is a concept whose time has come. This Sourcebook and subsequent BioTown reports will serve as vital stepping stones to the implementation of BioTown, USA and subsequent bioeconomic rural development opportunities across Indiana and the nation.

Good News from the DOE about Carbon Sequestration

According to a new Department of Energy study U.S. and Canadian power plants are sitting on a 900 year storage capacity for their carbon sequestration. Getting the CO2 underground into the subterranean storage formations is not a process currently practiced in the United States (as it is in Europe) but it is good to know that we have the capacity to use as part of an overall carbon mitigation program.

DOE’s Carbon Sequestration Program involves two key elements for technology development: (1) Core R&D and (2) Demonstration and Deployment. The Core R&D element contains five focal areas for carbon sequestration technology development: (1) CO2 Capture, (2) Carbon Storage, (3) Monitoring, Mitigation, and Verification, (4) Non-CO2 Greenhouse Gas Control, and (5) Breakthrough Concepts. Core R&D is driven by industry’s technology needs and is accomplished through laboratory and pilot-scale research aimed at developing new technologies and new systems for GHG mitigation.


As shown in this Atlas, CCS holds great promise as part of a portfolio of technologies that enables the U.S. and the rest of the world to address climate change while meeting the energy demands of an ever increasing global population. The Atlas includes the most current and best available estimates of potential carbon dioxide (CO2) sequestration capacities determined by a methodology applied consistently across all of the Regional Carbon Sequestration Partnerships (RCSP). All data were collected before December 2006. In the course of developing these CO2 sequestration capacity estimates, it became clear that some areas had yielded more and better quality data than others. Therefore, it is acknowledged that these data sets are not comprehensive; it is, however, anticipated that CO2 sequestration capacity estimates as well as geologic formation maps will be updated annually as new data are acquired and methodologies for CO2 sequestration capacity estimates improve.

Bridging the Gap to Biofuels


When it comes to energy, we are all stakeholders – whether we are producers, refiners, developers, educators, policymakers, marketers, regulators, environmentalists, distributors, farmers, foresters, or simply commuters... we are all consumers with a vested interest in future development of renewable energy in concert with environmental sustainability.

Even though there is a growing global recognition that something must be done to reduce dependence on fossil fuels and mitigate carbon emissions, the potential for endless debate over the means to these ends is threatened by delays. We need to act now.

The success of any mission to achieve 25x’25 or Twenty in Ten is more dependent on our willingness to communicate and work together than it is on our technical achievements. Why? I am convinced it will take collaboration between all stakeholders to develop and deploy these emerging technologies.

Having attended three important conferences this month, perhaps the most important lesson I can share is one for “bridging the gap” that I learned at 25x’25. When negotiating all parties must take an attitude of “Yes, if...” rather than “No, because...”

For example, “Will you agree...?”:
• “Yes, if you will guarantee...
• “Yes, if you can convince...
• “Yes, if you can match...
• “Yes, if you will commit...

Without the proper spirit of collaboration no compact between stakeholders will be sustainable – even if the technology is.

Using fungi to produce ethanol & biodegradeable material

Biopact has run a story about a Swedish science team whose research into Zygomycetes (an order of more than 100 different fungi) has discovered a saprophyte that grows easily in waste and drainage that converts it into ethanol and can be used to extract an unbelieveably useful super-absorbent and antibacterial cell-wall material that is biodegradeable!

Is it April 1st yet? You might want to look at the source article that appeared in the European Research website. As they report "The bottom line is that this discovery will benefit not only nature, but the paper industry and manufacturers of diapers and feminine hygiene products as well."

Scientists discover fungus to convert biomass into ethanol, and into biodegradable antibacterial and super-absorbent material

A research team at University College of Borås in Sweden, headed by Professor Mohammad Taherzadeh, in collaboration with scientists from Göteborg University has made a unique discovery. It consists of a fungus that converts biomass waste into ethanol in a highly efficient manner. Moreover, from the residual biomass resulting from the ethanol production the researchers were able to extract a powerful antibacterial and super-absorbent material that can be used in the hygiene industry (medical and sanitary napkins, etc...). The material is biodegradable, and promises to solve a significant waste problem.

Being able to convert sulfite lye for the production of ethanol is good news, in both economic and environmental terms. Sulfite lye, which is a byproduct of the production of paper and viscose pulp, is difficult for factories to dispose of since it contains chemicals that must not be casually released in nature. From being a highly undesirable byproduct for the paper industry, sulfite lye will now be an attractive raw material for the extraction of ethanol:

"Today baker's yeast is used for the production of ethanol, but we have found a fungus that is more effective than baker's yeast," says Mohammad Taherzadeh, professor of biotechnology at the School of Engineering, University College of Borås, and one of the world's leading ethanol researchers.

Zygomycetes are not only highly effective in producing ethanol; the research team also found that the biomass that is left over in the production of ethanol can be used to extract a cell-wall material that is super-absorbent and antibacterial. What's more, it's a biological material that can be composted and recycled:

This discovery opens an entirely new dimension for research on the fungi, according to Mohammad Taherzadeh, whose project "Production of antimicrobial super-absorbent from sulfite lye using zygomycetes" was recently awarded more than 800,000 Swedish Crowns (€85,000/US$ 114,000) from the Knowledge Foundation to continue its research into this cell-wall material.
