Fuel from carbon dioxide_ still a losing proposition

If I told you that I had created a process to extract pure gold from seawater, you might deem it an amazing accomplishment. Gas news of manipur If I issued a press release stating these facts, it very well could go viral.

In fact, the oceans do contain an estimated 20 million tons of dissolved gold, worth close to a quadrillion dollars at the current spot market price. Gas upper back pain But you may have noticed that I have omitted a very important fact.

I haven’t mentioned how much it costs to produce a troy ounce of gold using the process I have designed. Gas chamber jokes That seems like an important detail, so I explain that the production cost is only $50,000 or so per ounce (which today is worth about $1,265), but I am sure that with enough investment dollars — and maybe a few government subsidies — I can get that cost down to something more reasonable. Gas oil ratio calculator (This is how we subsidize some advanced biofuels where production costs are an order of magnitude above what could be considered economical).

Readers immediately understand the problem. Gas near me cheap You don’t spend more to produce something than you can sell it for. Gas x while pregnant But change the equation to energy instead of money and people suddenly forget that lesson. 5 gas laws Or they fail to recognize that is what is taking place.

That brings me to the point of today’s article, one I’m forced to reiterate often: in the world of energy as in most others, there is no free lunch.

Earlier this month a research paper was published by the Department of Energy’s Oak Ridge National Laboratory (ORNL) called “ High-Selectivity Electrochemical Conversion of CO2 to Ethanol using a Copper Nanoparticle/N-Doped Graphene Electrode.” The paper reports on some truly interesting science, and the researchers were measured and cautious in their conclusions.

But something got lost in translation as media outlets sought to portray this as a “holy grail,” “game changer,” “major breakthrough” or “solution to climate change.” The benefits, one story said, were unimaginable. Electricity 101 youtube Part of the problem, in my opinion, is that the press release from the Department of Energy was titled Scientists Accidentally Turned CO2 Into Ethanol.

The word “accidental” plays into the misconception people have of how science is done. Electricity trading Many take the romantic view that game-changing, eureka discoveries are merely awaiting the next lucky accident, so when they read this headline the translation becomes something like “New Discovery Solves Climate Change.”

That’s because the public loves its energy miracles. Gas prices in michigan People love the idea of a car that can run on water or the car that gets 400 miles per gallon (which of course GM and Ford suppressed) or the magic pill you can pop in your tank that greatly enhances fuel efficiency. Eseva electricity bill payment So it isn’t surprising that this kind of story goes viral (in notable contrast to the articles debunking these viral stories.)

If you burn something containing a combination of carbon, hydrogen, and oxygen — e.g., gasoline, ethanol, wood, natural gas — that combustion reaction is going to produce heat, carbon dioxide and water. Electricity definition wikipedia These are the combustion products.

It is possible to reverse the combustion reaction and convert that water and carbon dioxide back into fuel. Gas efficient suv 2008 But you have to add heat. 8 gas laws A lot of heat. La gastronomia How much? More than you can get from burning the fuel in the first place. Gas yoga No new catalyst, and no discovery, accidental or otherwise, can get around that fundamental issue without overturning scientific laws observed and confirmed over 150 years.

Given that, what can we say immediately about this process? Going back to the fundamentals of thermodynamics, we can say, without a doubt, that the process consumes more energy than it produces. Electricity lab physics In other words, to produce 1 British thermal unit (BTU) of ethanol will require the initial consumption of more than 1 BTU of energy (and generate CO2 emissions.) The resulting 1 BTU of ethanol would ultimately be consumed. Victaulic t gasket The net effect once the ethanol is consumed is more than 2 BTUs’ worth of emissions per BTU of ethanol produced. Wb state electricity board bill pay Or, to be blunt, unless the process can be run on excess renewable or nuclear power (more on that below), converting carbon dioxide into ethanol would actually worsen net carbon dioxide emissions.

Now the researchers involved certainly know this. Gas bubbler They actually acknowledged in the paper that the process is unlikely to be economically viable. Gas vs diesel prices To my knowledge they haven’t intentionally misled anyone.

But the public has been misled in the retelling of the story. Gas bloating frequent urination I have heard this research presented as “an efficient way of removing carbon dioxide from the atmosphere.” No, that’s not at all what the researchers claimed. Electricity notes They claimed a Faradaic efficiency in the process of 63%. Electricity jeopardy 4th grade In other words, 63% of the electricity used in process was utilized in the reaction. Bp gas prices They further said that 84% of what was produced was ethanol. Gas laws worksheet That’s the “high-selectivity” part of the title.

But that says nothing at all about the energy consumption required to remove carbon dioxide from the atmosphere so it can participate in this reaction. V gashi 2012 That is an enormous energy cost because carbon dioxide exists at only 400 parts per million in the atmosphere. 9gag wiki Or in the case of passive removal (which is what plants do by means of photosynthesis), the process is very slow.

The high Faradaic efficiency and selectivity also provide little information about the overall energy requirements to turn purified carbon dioxide into purified ethanol, but we already know that it’s more than the energy contained in the ethanol. Gas in babies And it could be a lot more, and that could result in a lot more carbon dioxide emissions.

There is a way that a process like this that is an energy sink could be viable, and that would be if you had cheap, surplus energy that might otherwise be wasted. Gas tracker For example, if a wind farm or nuclear plant produced far more electricity than the grid could handle, you could envision dumping the excess power into such a process. 3 gases that contribute to the greenhouse effect That could in theory reduce carbon dioxide emissions, but there are a lot of caveats that would warrant a longer discussion. Yoga gas relief pose Such an intermittent process brings up its own set of issues, and then there’s the question of whether that would really be the best use of the surplus energy.

The bottom line here is if someone presents a scheme for turning air, water, or carbon dioxide into fuel, it is necessarily consumes more energy than it produces. Gas and electric phone number It is an energy sink.

It is surprising to me, to read basic science research and to gain an understanding on how much we do not understand. Electricity physics The report on JILA team using laser spectroscopy operating through glass dome to ID chemical reactions. U gas station Basic reactions of ICE engine combustion. Gas after eating yogurt They vary input constituents to map out generation of chemical power and pollution. Electricity japan They plan to study CO2 and water reactions to understand better the process on why oceans acidify. Electricity outage in fort worth You see this is basic stuff and a foundation to build better solutions. Gasbuddy va Up until know scientist only had theories (no actual observation of real time chemistry) of the combustion and interplay of water, nitrogen, carbon fuel, extreme pressure and heat. Gas variables pogil worksheet answers So, how can are environmental scientist plot out our future time frame of demise per exact GW science? They can’t it’s just an exercise in speculation that is hyped up per our political journalist, that neglect to inform the public of the inaccuracy of the science.

Science hadn’t known that CO2 could directly be converted to ethanol and done with low cost alloy. H gas l gas brennwert By the discovery and investigation, this will lead us to better understanding of the science and as a result will move the bar upwards to better more cost effective solutions.

I read a updated study (White Paper) on auto technology as the old five year study was already inaccurate as technology advanced. E suvidha electricity bill lucknow We take these snapshots of static conditions and attempt to extrapolate the future. A gas mixture is made by combining GW and renewable power enthusiast both continually make inaccurate projections and do so upon historical trends, (the most out of date data possible). Electricity consumption Activist journalist will again hype such sketchy info to public for fear mongering and do so I believe for their trade union political gain and personal promotion. Electricity schoolhouse rock So, if we could possible divert or subvert this entertainment science to educate and inform the public of the true merits of the science, we would indeed have a powerful nation of truly educated thinkers. Ideal gas kinetic energy Just saying.
