Making Good Use of CO2.
Can We Recycle CO2 Emissions to Make Carbon-Neutral Fuel?
Our failure to curb our carbon emissions is threatening to cause catastrophic climate change within our lifetimes. But what if we could recycle CO2 emitted by power stations and turn it into fuels and valuable chemicals? A new analysis suggests this may be possible within a decade.
From article, (Our failure to curb our carbon emissions is threatening to cause catastrophic climate change within our lifetimes. But what if we could recycle CO2 emitted by power stations and turn it into fuels and valuable chemicals? A new analysis suggests this may be possible within a decade.
Despite progress in renewable energy development, our present trajectory seems unlikely to prevent the 2°C rise in temperature that most experts say would have a disastrous impact on all life on Earth.
That’s prompting a growing number of people to look for alternatives, and one of the leading candidates is carbon capture and storage technology. Chemicals are used to extract CO2 from the exhaust of power stations, and the gas is then piped to a storage location (normally deep underground in depleted oil or gas reservoirs), preventing it from reaching the atmosphere.
But new analysis from researchers at the University of Toronto suggests this method could be a waste of a valuable resource. A new paper in the journal Joule argues that technology that uses electricity and water to reduce CO2 into simple hydrocarbon fuels or small molecules that can act as feedstock for more valuable chemicals could be economically viable in the next five to ten years.
There’s an obvious precedent for using atmospheric CO2 to make fuels and other useful chemicals—the very process that created fossil fuels in the first place.
“Similar to how a plant takes carbon dioxide, sunlight, and water to make sugars for itself, we are interested in using technology to take energy from the sun or other renewable sources to convert CO2 into small building block molecules which can then be upgraded using traditional means of chemistry for commercial use,” Phil De Luna, a PhD candidate and one of the paper’s lead authors, said in a statement.
Turning captured CO2 back into fuels and chemicals rather than burying it underground doesn’t just present a way to monetize what is currently being treated as a waste product. The researchers point out that it could actually help solve the energy storage problem caused by increasing reliance on intermittent renewable sources like solar and wind.
If renewable energy sources are used to power the conversion of CO2 into fuels, the result is effectively carbon-neutral hydrocarbon fuels. These can be stored for use when renewables alone aren’t able to meet demand or used to power vehicles, and importantly, they can take advantage of our preexisting infrastructure of pipes and storage tanks designed for fossil fuels.)
98 GW of New Solar Power was installed in 2017 and $2.9 Trillion dollars has been spent on green energy since 2004.
From article, ("The world added more solar capacity than coal, gas, and nuclear plants combined," Nils Stieglitz, president of the Frankfurt School of Finance and Management, said. "This shows where we are heading, although the fact that renewables altogether are still far from providing the majority of electricity means that we still have a long way to go."China becomes a 'driving power' for solar energy with $86.5 billion invested last year
Guo Chen | Xinhua News Agency | Getty Images The world has invested $2.9 trillion in green energy sources since 2004, according to new research, with China leading the way in recent years with its push towards solar power.
The world has invested $2.9 trillion in green energy sources since 2004,
98 gigawatts (GW) of new solar capacity was installed in 2017.
solar power attracted $160.8 billion of investment, more than any other technology. China, where a staggering 53 GW was added and $86.5 billion invested, was described as a "driving power" behind the increase in solar.
"The extraordinary surge in solar investment shows how the global energy map is changing and, more importantly, what the economic benefits are of such a shift," Erik Solheim, the head of UN Environment, said in a statement.
"Investments in renewables bring more people into the economy, they deliver more jobs, better quality jobs and better paid jobs," he added. "Clean energy also means less pollution, which means healthier, happier development."
The report found that China invested the largest amount of money in renewables last year, at $126.6 billion. This represents a 31 percent increase compared to 2016. Around the world, 157 GW of renewable power was commissioned last year.)

What to do with Glass Bottles? It is very difficult to recycle, the different colors can throw off a batch, and the Glass Bottle Market has shrunk, forcing it to be used as Road Filler or Just Thrown In A Landfill.
If recycling glass becomes almost impossible, what can be done with it? Grind it up, of course
As municipalities wrestle with marketplace changes that are making it almost impossible to recycle glass, the second "R" in the environmental slogan Reduce-Reuse-Recycle is becoming more attractive.

From article, (As municipalities wrestle with marketplace changes that are making it almost impossible to recycle glass, the second “R” in the environmental slogan Reduce-Reuse-Recycle is becoming more attractive.
In the town of Warner, the attraction of reusing rather than recycling glass has been obvious for decades.
“Since we started the transfer station, in 1989 … we have been diverting glass out of the waste stream,” said Varick Proper, foreman of the Warner transfer station.
The town grinds up the bottles and jars that residents drop off and uses the resulting material as a substitute for gravel or sand. After the glass is crushed, it looks surprisingly drab and is sometimes given the punning name “glassphalt,” in various construction projects.
“We have just an old grinder that has been converted to beat up the glass,” said Tim Allen, the town’s director of public works. He said the town generates around 80 to 90 tons of material a year, which is used along with gravel and sand, or even in place of it, for such things as roadbeds or doing remediation work at the town gravel pit.
This has a two-fold financial benefit: It makes use of material that the town would otherwise pay to get rid of, probably by shoving into a landfill, and replaces some sand and gravel that the town would have to buy or dig up itself.
Warner may have been ahead of the curve but it’s not alone in seeking to turn residents’ glass into usable material. In nearby New London, Director of Public Works Richard Lee is such an advocate of crushed glass that he’s featured in a video from the Northeast Resource Recovery Association, a recycling industry group, in which he talks about how properly processed, it can be used to make the surface of roads without endangering rubber tires.
The NRRA is trying to increase reuse of old glass in construction. It owns a portable crusher that it takes to various collection points around the region to help communities that don’t have their own systems.
The video also discusses research by the U.S. Army Corps of Engineers that said processed glass aggregate is as good or better than gravel in terms of “frost susceptibility,” or the ability to cope with the expansion and contraction of freezing water during winter.
Elsewhere, efforts are underway to develop other uses for recycled glass, including a new factory in Philadelphia that seeks to use glass to replace aggregate in making concrete, or to use foaming agents with it to create a lighter-weight filler material.
The reason for all this activity is that the obvious thing to do with glass – turning old bottles into new bottles – is increasingly difficult. The major reason is that fewer things are packaged in glass, as compared to plastic, these days, so the market for recycled glass is shrinking.
The problem has been growing for several years but really hit home for New England in January when a bottle-making factory in Medford, Mass., closed because of a decline in business from national beer companies. It annually bought some 2,000 tons of “cullet,” the industry term for recyclable glass.
Combine this market decline with the difficulties of handling glass, keeping different colors of glass separate, and keeping out similar but unusable material that often gets mixed with bottles at transfer stations, like window glass and ceramics, and recycling glass has become almost impossible.
“It’s a problem nationwide. There are a number of places that have gone back to trashing it – done so reluctantly,” said Proper. “The problem with reclaiming glass, recycling it back into a glass bottle, is that you have to hit such a degree of purity that it’s very hard in a post-consumer state. One bottle cap or the wrong color glass can really fowl the whole mix.”)
Nikola Motors Refund of Deposits is Just Smoke and Mirrors. They are Making Money on Pre Orders and Can Afford to Give Back Deposits. It's Basically Taking Money Out of One Pocket and Getting it From Another.

Nikola Motor, a company developing several electric vehicles, including a battery-electric and hydrogen fuel cell semi truck, announced that it is refunding all deposits for reservations on its trucks and it took a swipe at Tesla in the process.
the company has a bad habit of taking unnecessary shots at Tesla, which Nikola has been arguably modeling itself after in some ways – not only because of their name, but also for launching an energy division just like Tesla.
In its latest announcement, the company says that it is refunding all deposits for reservations on its trucks:
“Great news! All reservations will be refunded 100% and you won’t lose your place in line. We don’t use your money to operate our business. We want everyone to know we have never used a dollar of deposit money to operate the company on like other companies do. You can now reserve the Nikola One and Two at https://nikolamotor.com/without any deposits. Our support team will be reaching out to everyone to refund their deposits over the next 30-60 days. How awesome is that!!!!!! Over 8 billion in pre orders, so who needs deposits.”
The reference to “other companies” is undoubtedly a swipe at Tesla, which is taking $20,000 reservations for the Tesla Semi electric truck.
It’s not the first time that companies have attacked Tesla over their reservation process. Nissan also criticized it in a series of ads in 2016.
The Nikola One and Two will reportedly be equipped a 320 kWh battery pack and a fuel cell system, which Bosch is helping design. After launching the vehicle in 2016, Nikola claimed to have a backlog of 7,000 orders worth $2.3 billion.
Now they have claimed that it increased to $8 billion over the last 2 years.)
