Greening Introduction

REFERENCES AND THEIR USES – A late night musing

The Intergovernmental Panel on Climate Change (IPCC) is making changes to improve its scientific integrity. The move comes in part because of mistakes discovered in the panel’s 2007 assessment, including the incorrect statement that Himalayan glaciers would melt away by 2035.

Last year, the Inter Academy Council, a coalition of national scientific academies, recommended changes to IPCC to address these and other issues (C&EN, Sept. 6, 2010, page 15). At a meeting in mid-May, IPCC adopted a procedure for evaluating and correcting errors in its assessments. The group also established a standardized method for addressing scientific uncertainties in its reports, and it approved a new conflict of interest policy.

The present approach is compliant to the reviews of the IPCC by leading British and American Senior Technical advisory groups (e.g., NAS)

In addition, the panel set a benchmark for scientific literature used for its assessments. This gives priority to peer-reviewed studies but recognizes that reports from governments, industry, and research institutions may provide crucial data even if they aren’t peer reviewed. It states that magazines and newspapers are generally not valid sources of scientific in formation and bans the use of material from broadcast media, blogs, social networking sites, and personal communications of scientific results.

Note that the criteria the panel espouses are comparable to those I use in determining whether or not to use a reference in one of my articles.However, there is one major difference. I seldom use primary references (e.g., journals) as examples for further exploration for you my readers. First, such use of such would be counterproductive as a communications tool on the basis of knowledge accessibility.

Many of you, including my self, would be swamped by journal article contents in areas we had not studied Alternately if long ago studies, has evolved to the point where can not easily connect either with the concept details or newly evolved semantics. There for the contents would be, in terms of understanding, inaccessible to us!

Second, the entireties of journal articles are not easily available via Google and other publicly accessible search methods. Although, the abstracts of the article are, they are not detailed enough to serve as serious information even to a casual ‘knowledge-hungry’ reader. Again it’s a matter of access.

You can access full journal articles through a public library or local college library, only if the local agencies have individual subscriptions to that service. [No I’ve not tried the Library of Congress for journal\access detail.] Buying articles for archive reference copy use w/o the academic and public library discount is pricy… Certainly, as a routine expense, out of my budget. Indeed getting access to an occasional primary reference is the primary reason I maintain local library cards; other information is as easily available from my desktop iMac.

Therefore all of my references will remain secondary and shall only be used after a sanity, logic, and check on WIIFT <What’s in it for them>.

 New Reactor Harnesses Sun’s Energy Like Plants The science keeps getting us closer but we’re a long ways from commercial or even breakeven costs.

Researchers have unveiled a prototype reactor, which mimics plant life, turning the Sun’s energy to make hydrocarbon fuel. Developed by a team of scientists from the United States and Switzerland, The device uses the Sun’s rays and the mineral ceria (cerium oxide), to break down water or carbon dioxide into energy, which can be stored and transported.

Harnessing the power of the sun has been but a pipe dream, as conventional solar panels must use the power they generate in situ. With the ceria-fueled reactor, this issue is solved

The scientists, who include Caltech professor Sossina M. Haile and Swiss Institute of Energy Technology professor Aldo Steinfeld, wanted to figure out a way to harness the sun efficiently, without incredibly rare materials. They decided on testing ceria, a relatively abundant “rare-earth” metallic oxide with very special properties.

The solar reactor takes advantage of the ceramic ceria’s ability to “exhale” oxygen from its crystalline framework at very high temperatures and then “inhale” oxygen back in at lower temperatures. “What is special about the material is that it doesn’t release all of the oxygen. That helps to leave the framework of the material intact as oxygen leaves,” Haile explains. “When we cool it back down, the material’s thermodynamically preferred state is to pull oxygen back into the structure.”

 Carbon Sequestration NETL Core R&D — The DOE Program

Many of you know that I have grave doubts about carbon sequestration, putting carbon, as a gas, in underground geological repositories.  Nevertheless, in the interest of fairness, DOE’s efforts on the topic are summarized below, the information taken from their The National Energy Technology Laboratory (NETL) web pages. I am pleased to note that other, international efforts are approaching the demonstration stage, but still fear for the risks associated with diverse environmental (geohydrologic-seismic) environments for any site-specific demonstration of long-term storage or disposal. Each and every location, not just environmental setting, must be proven safe for the so-called ‘disposal’ period, despite effect of plate tectonics (earthquakes) and perhaps climate change. [Think nuclear waste repositories.] 

Therefore herein, I am sharing only information focused primarily on the two areas of Pre-Combustion Capture and CO2 Utilization. However, the references I, link to all the current DOE efforts, my interests continue to mainly focus only on areas where the long term economic risk is a more important factor than the environmental ones.

The DOE Core Research and Development (Core R&D) focuses on developing new carbon capture and storage (CCS) technologies to a pre-commercial demonstration level. The Core R&D Element includes five technical focus areas: (1) Pre-Combustion Capture; (2) Monitoring, Verification, and Accounting (MVA); (3) Geologic Storage; (4) Simulation and Risk Assessment; and (5) CO2 Utilization.

From my perspective, until the issue of ‘licensing’ geologic site for long storage [… let’s say 100 -300 years> or disposal < ≥ 1000 years> is actually address and consensus reached on it resolution, the most useful part of the pram is the isolation, capture and reuse of the CO2 we emit in generating electricity from coal, oil, and natural gas. Remember, CO2has no half-life. If we don’t concert it to a solid mineral form or release it to challenge the next ice ago, it will do damage whenever it get released back in to the atmosphere.

Carbon dioxide (CO2) capture is defined as the separation of CO2 from emissions sources or from within the CO2 emission process. When CO2 is recovered from emissions sources, such as power plant flue gases, it is in a concentrated stream that is amenable to storage or conversion. Currently this process is costly and energy intensive, accounting for the majority of the cost of storage.

The Carbon Sequestration Program (Pre-Combustion Capture Focus Area) is focusing on developing technologies used to reduce the cost of capture and separation of CO2 in pre-combustion systems. Pre-combustion capture is mainly applicable to Integrated Gasification Combined Cycle (IGCC) power plants and refers to removal of the CO2 from the synthesis gas (syngas) prior to its combustion for power production. CO2 is concentrated and at a high-pressure as a result. A simplified process schematic for pre-combustion CO2 capture is shown below. Near-term applications of CO2 capture from pre-combustion systems will likely involve improvements to the existing state-of-the-art physical or chemical absorption processes being used by the power generation industry.

Carbon dioxide (CO2) utilization efforts focus on pathways and novel approaches for reducing CO2 emissions by developing beneficial uses for the CO2 that will mitigate CO2 emissions in areas where geologic storage may not be an optimal solution. CO2 can be used in applications that could generate significant benefits. It is possible to develop alternatives that can use captured CO2 or convert it to useful products such chemicals, cements, or plastics. Revenue generated from the utilized CO2 could also offset a portion of the CO2 capture cost.

Processes or concepts must take into account the life cycle of the process to ensure that additional CO2 is not produced beyond what is already being removed from or going into the atmosphere. Furthermore, while the utilization of CO2 has some potential to reduce greenhouse gas emissions to the atmosphere, CO2 has certain disadvantages as a chemical reactant. Carbon dioxide is rather inert and non-reactive. This inertness is the reason why CO2 has broad industrial and technical applications. Each potential use of CO2 has an energy requirement that needs to be determined; and the CO2 produced to create the energy for the specific utilization process must not exceed the CO2 utilized.

 The Commuter Bike Redesigned and Electrified — If I was a rich man…

This week, most people on the East Coast were hunkering down indoors, prepared for this winter’s fourth Snowstorm of the Century. I (Dave Pouge) on the other hand, was riding around a hotel ballroom on a YikeBike. And I’ll be straight with you: I had kind of a Segway moment.

Remember that? After inventor Dean Kamen first gave secret demos of his self-balancing upright scooter to industry hotshots, their awed reactions included remarks like, “They’ll redesign cities for this thing.” Of course, the Segway never did become as commonplace as the bicycle, and the YikeBike won’t either. But what a cool idea.

It’s an electric bike. Top speed is about 15 miles an hour. Buttons that are right under your thumbs on the handlebars smoothly controls the accelerator and brakes. The handlebars themselves are at your waist level, which might seem odd but makes sense—you ride sitting fully upright instead of bending forward, as on a bicycle. That design also means that you can jump forward off the bike in a crisis; there’s no hardware in your way.

Here’s the twist: the whole thing folds down into its own front wheel. You undo four stainless-steel latches, then snap the back wheel, seat and handlebars into the front one. It takes about 10 seconds. (Watch the video embedded in the linked post to get the idea.)

After providing lots more details, David notes,I’m not sure how many takers of the high tech carbon composite the YikeBike will have at $3,600. But I really admire Mr. Ryan’s lean, green folding machine, and I wish him the best of luck.”

 Pollution & Global Warming—Climate change in black and white

As noted in a recent Economist article, black and white (data) has many grey aspects. When air pollution hurts people’s health and heats up the climate it makes sense to do something about it. But, what about pollution that cools the planet?

An ideal fossil-fuel power plant would produce power, carbon dioxide and nothing more. Less-than-ideal ones—not to mention other devices for the combustion of carbon, from diesel generators to brick kilns and stoves burning dung—also emit various gases and gunk. These often cause local environmental problems, damaging lungs, hurting crops and shortening lives. And some of the gunk, notably soot or “black carbon”, can warm the planet, too.

Next week (February 28, 2011) ministers attending the governing council of the United Nations Environment Programme (UNEP) in Nairobi will be presented with the summary, which I could not find, of a new report on how fighting air pollution can help the global climate (the report itself is due to follow a couple of months later). The summary makes a powerful case for acting on two short-lived climate “forcing’s”, factors that change the amount of energy the atmosphere absorbs, as carbon dioxide does, but stay in it only briefly. One is black carbon and the other is ozone. The later is both vital for blocking ultraviolet rays in the stratosphere but hazardous in the bits of the atmosphere where plants live and people have to breathe.

According to the UNEP report, implementing measures known to be effective against these two pollutants over the next 20 years would have “immediate and multiple” benefits. These include (1) average world temperatures between 0.2°C and 0.7°C lower than they would otherwise be by 2050 and (2) the saving of between 0.7 and 4.6 million lives with improved air quality. For black carbon the measures are largely in the form of more efficient ways of burning things; for ozone they mostly involve reducing emissions of methane, which encourages reactions in the atmosphere that make ozone. The black-carbon measures save a lot more lives than ozone control, but are trickier to assess in terms of climate

Beijing, but it could have any major urban industrial community in Asia.

The article continues with a discussion of the history of UNEP’s interest in black carbon including observations initiated by Veerabhadran Ramanathan, of the Scripps Institute of Oceanography in La Jolla, California, and Paul Crutzen, a Dutch climate scientist who was one of the first to theorize about “nuclear winter”. These studies revealed the hitherto unappreciated extent of an “Asian brown cloud” thousands of kilometers across and fed by fires, diesel fumes and all manner of other things.

The article then focuses on the climate politics, as opposed to the science of black carbon; since reducing CO2 release internationally seems stalled politics takes the forefront. [Check it out, this is not intuitive. It’s an interesting read for the non-politicians amongst us.]

The article, lengthy but well written, ends with a straight forward section called “Clouding the Issues” that deals with both potential warming and cooling effects of atmospherically distributed and surface settled carbon soot. Who said science is black or white?

There’s no punch line but the realization at times, due to doubling effects, more R&D is needed before any action makes sense, especially from regulatory forcing factors.

Indeed, if the Arctic is warming faster than might be expected, other parts of the world are warming slower. One reason for this, widely accepted by scientists but little appreciated by policymakers, is that the sulphur given off by coal-fired power stations and some other industrial fossil-fuel use. Sulphur is very good at forming reflecting aerosols that can also make natural clouds both whiter and possibly longer lasting, which provides an added cooling effect. Acid rains anyone?

It is no coincidence that a non-governmental organization active in the fight against air pollution, America’s Clean Air Task Force, now strongly advocates more research into the pros and cons of geoengineering. Jason Blackstock, at the Centre for International Governance Innovation in Waterloo, Canada, points out that black carbon; sulfates and geoengineering are all neglected by the institutions that govern climate policy. He is looking at ways to bring the topics together in the broader context of how nations make choices about the climate. If human action on the climate is ever to be properly deliberate, it must first be properly deliberated.

This is a thought-provoking read that should threaten any ‘nature is simple paradigm’. I’ll be doing an Op-Ed analysis on Geoengineering for release in July; keep clicking to keep me honest and on schedule.

 Symbiotic Coupling Of Wind Power And Nuclear Power Generation Finally someone serious about merging green power, renewable but intermittent Wind and greenhouse free baseload effective nuclear.

I’ve copied the abstract from the peer reviewed Proceedings of the 1st International Nuclear and Renewable Energy Conference (INREC10), Amman, Jordan, March 21-24, 2010. The paper by Kate Rogers and Magdi Ragheb from the Department of Electrical and Computer Engineering and the Department of Nuclear, Plasma and Radiological Engineering at University of Illinois at Urbana-Champaign. A bit of disclosure, I got my Ph. D. in Organic Chemistry for the U of I at Urbana.

Why?  It has always perplexed me why so little has been published about use of coupled technologies (e.g., nuclear and wind or solar; and perhaps geothermal and wind power) in trying to get cost effective and function solutions to our energy needs while minimalizing direct worsening greenhouse gas releases? The life cycle releases still remain since you must mine-smelt-manufacture the facility, deal with land use footprint and water issues. However these environmental costs are a small portion of the pollution costs of facility based on transporting and burning hydrocarbons for 20-40 years. Okay, here’s the abstract. Check out the whole article…as Arthur Stanton Eric “Arte” Johnson would say on Laugh in, ’it’s verrry interesting.

The coupling of wind power production as an intermittent supply to nuclear power generation as a base load supply is discussed. Wind turbines on a standby operational mode are net importers of power for their control and yaw mechanisms. They need a supply of about 5 kW of power from an existing grid. They also require the vicinity of a power grid with excess capacity to export their generated power. A choice is the construction of wind farms in the immediate vicinity low population density population zones around nuclear power plants.

An example, used by the authors, is the Grand Ridge wind farm adjacent to the LaSalle nuclear power plant near Versailles, Illinois. Since the best wind resources in the USA are located far from the industrial and population centers there is a need for connection to the grid trough High Voltage Direct Current (HVDC). Due to ramping considerations, the planned introduction of 20 percent of electrical wind production in the USA by 2020 would pose challenging grid stability issues. Energy storage alternatives such as hydrogen production, compressed air, flywheels, superconducting magnets and pumped storage, need serious consideration. Doc agrees as long as the results are integrated into life-cycle system operations consideration… To misquote John Donne — no widget is an island!

 Nuclear Efficiency — With new fuel formulations, reactors could extract more energy, and reduce hazardous waste

When it comes to nuclear energy, the world is not exactly an early adopter of new technology: The vast majority of nuclear reactors running today falls into the so-called Generation II category and uses technology from the 1970s. Generation III reactors—the ones being built now or in the near future—are fundamentally based on the same water-cooled design, with improvements in safety, reliability, and efficiency.

It is in the development of Generation IV reactors—the ones that will start up around 2030—that nuclear energy will see a significant change in technology. The six models put forth by the Generation IV International Forum, chartered in 2001 to carry out nuclear energy research and development, aspire not only to be even safer and more reliable than previous generations, but also to get a greater return from the energy source—by extracting up to 90% of the available energy in their fuels instead of the 5% more typical of today’s reactors. In some cases, the reactors will use reprocessed or recycled waste fuel from other reactors. The fuels may also incorporate some of the longest lasting radioisotopes from waste fuel, including americium, curium, and neptunium, thereby turning these radiotoxic isotopes into less hazardous materials while providing a little extra energy in the process. To reach those goals, and especially to reach them safely, nuclear scientists are working to develop and evaluate new fuel formulations and materials.

Current reactors use either uranium dioxide or a mix of uranium dioxide and plutonium dioxide. The fuel powder is pressed into pellets that are about 1 cm in diameter. The pellets are then inserted into thin tubes to form rods. The tube material, known as cladding, is considered an integral part of the fuel. In traditional reactors, the cladding is a zirconium alloy.  After the rods are sealed, they are assembled into bundles of dozens to hundreds of rods; several hundred of the bundles make up the core of a reactor.

Jyllian N. Kemsley goes on to discuss, in a well-written and clearly illustrated fashion, the Generation IV reactors and how they will and can achieve bowered costs, safer operation and minimal need to dispose of high-level long lived radioactive waste. What I drew me to this article was the realization that outside of the US, that future is becoming now!

 Is the Coal Killer Flying Thousands of Feet Up in the Sky? — A new meaning to go fly a self powered kite.

JoeBen Bevirt is building an inventive, flying turbine in a bold bid to make wind power practical. Bonny Doon, California is hardly the place one thinks of visiting for high-tech thrills. Once an old logging camp, the tiny hamlet northwest of Santa Cruz, California, sits at the end of a country road, past miles of empty beaches and strawberry farms. Hang a left before you reach the vineyard and you find a short dirt track leading to a barn. And then, amid hundreds of acres of redwoods out back, you encounter an avatar of the future—a whirring black gizmo, about the size of a bread box, zipping around overhead. The strange flying object is controlled remotely by a cluster of giggling engineers. Their leader, a tall man with the build of a gazelle, windswept blond hair, and a permanent grin, starts extolling the possibilities of his device before he remembers to introduce himself.

To inventor JoeBen Bevirt, the flying black box holds our clean-energy future, a world in which wind turbines lift off the ground and fly among the clouds. His company, Joby Energy, designs these turbines from scratch. “In order to have truly sustainable energy, we’ve got to beat coal,” he says. “We are going to need game-changing technology. I believe that technology is high-altitude wind.”

In concept his idea makes sense: Wind power from the sky would strip turbines of their expensive, heavy towers and oversize blades, allowing them to collect energy unobtrusively from the richest lode of wind in the world. Winds at an altitude of 30,000 feet carry 20 times as much energy as those near the ground, representing a source of power that could be a fraction of the cost of coal. The challenge, observers say, is keeping such turbines aloft. ——— Enjoy, read the rest of the article summary-The full version is, alas, available only to subscribers like me.

 IAEA Fujushima Dalichi Fact Finding Mission Summary and Initial Findings_ A reference masquerading as a topic. I will deal with this topic in March of 2012, when most of the sound and fury has died down, and the facts have been collected, subject to peer review and published.  Meanwhile, we likely be watching the field days being enjoyed both by the anti-nuclear greens and the folks at big oil-coal and gas who profit as the earth appears to warm. From their perspective the only significant competitor, in the absence of a carbon tax, of CO2 and other green house gas free energy is being politically assaulted. No the nuclear renaissance is not dead, some government’s believe both killing their people with smog, and supporting the onward going warming is wrong.

I’ve been wondering whether the European Union, and perhaps the UK and Japan might impose a Value Added Tax [VAT] on product produced with electricity generated by pollution based plants. How? It’s naively simple. The VAT should be the ratio of ‘clean to polluting energy generated within the exporting country, other than transportation related. I know it’s in constraint of trade, but so are likely rising sea levels and the drowning of our port cities.

QUOTE de Mois — A Richard Feynman Cornucopia

  • The first principle is that you must not fool yourself and you are the easiest person to fool.  I believe that a scientist looking at nonscientific problems is just as dumb as the next guy.
  • For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.
  • Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man’s struggle for good and evil seems inadequate.
