Scientists are building a system that could turn atmospheric CO2 into fuel

Scientists in Canada are developing an industrial carbon dioxide recycling plant that could one day suck CO2 out of the atmosphere and convert it into a zero-carbon e-diesel fuel. Developed by tech start-up Carbon Engineering and partly funded by Bill Gates, the system will essentially do the job of trees, but in places unable to host them, such as icy plains and deserts.

Just like these new solar cells that are designed to split water into a hydrogen fuel, the CO2 recycling plant will combine carbon dioxide with hydrogen split from water to form hydrocarbon fuel. The plan is to provide the technology that could one day produce environmentally friendly fuel to complement the renewable energy systems we have now. “How do you power global transportation in 20 years in a way that is carbon neutral?” Geoff Holmes, business development manager at Carbon Engineering, told Marc Gunther at The Guardian. “Cheap solar and wind are great at reducing emissions from the electricity. Then you are left with the transport sector. Carbon Engineering is one of a handful of companies around the world that are now set on coming up with ways to suck enough carbon dioxide out of the atmosphere to actually put a dent in the effects of climate change. There’s also the New York City-based start-up Global Thermostat, and Swiss-based Climeworks, which demonstrated earlier this year with Audi how its technology can capture carbon dioxide, and deliver it to German company Sunfire, where it was recycled into a zero-carbon diesel fuel

While Climeworks’ demonstration was impressive, what all three companies now need to do is figure out how to make their atmospheric carbon dioxide to fuel systems economically viable. And this won’t be easy. One problem they’re going to have to overcome is the high cost of heating their carbon dioxide to around 400 degrees Celsius so they can process it properly. Another problem is that few investors are interested in giving them money until they can prove that this is actually feasible.

As Gunther reports for The Guardian, governments and private investors aren’t interested in paying anyone to come up with ways to simply suck carbon dioxide out of the environment, no matter how beneficial to the environment it might be. Plus even if someone was interested, they’d better be willing to fork out the billions of dollars it’s going to take to build a system that could actually make a discernible difference to the world’s climate. These developers need to offer their investors something valuable in return, and the obvious answer is fuel.

co2-capture

Right now, Carbon Engineering’s planned system could only capture only about 450 tonnes of CO2 each year, which would barely cover the carbon emissions of 33 average Canadians, but they say this system could be scaled up to 20,000 times to make it more practical.

As the video explains below, direct air capture seems to be the only potentially feasible way to absorb carbon dioxide that’s already been emitted from small mobile sources such as cars, trucks, and planes, which make up 60 percent of carbon dioxide emissions today. The systems require 1,000 times less land than carbon-sucking trees, and can be installed on land, like desert plains, that isn’t worth cultivating or inhabiting.

“I believe we have reached a point where it is really paramount for substantive public research and development of direct air capture,” Klaus Lackner of Arizona State University’s Centre for Negative Carbon Emissions said at the American Physical Society meeting in the US earlier this year.

“Scientists are increasingly convinced that we are going to need large scale removal systems to fight climate change,” Noah Deich from the California-based Centre for Carbon Removal told The Guardian. “I’m excited about direct air capture. It could be a really important technology to add to the portfolio.”

Watch the video below to see how Carbon Engineering plans on doing it. It’s going to take a while before we see the captured carbon to fuel model become a viable solution, but that’s not stopping the likes of Carbon Engineering, Climeworks, and Global Thermostat. We’re excited to see what they come up with.

World Approves Historic ‘Paris Agreement’ to Address Climate Change

Negotiators from nearly 200 countries reached an agreement Saturday on what they say signifies the most important international pact to address climate change since the issue first emerged as a political priority decades ago.

French Foreign Minister Laurent Fabius, who headed up the United Nations conference, commonly known as COP 21, said the final deal successfully resolved points of contention that had taken negotiations into overtime and called the agreement “the best possible text.”

“We have come to a defining moment on a long journey that dates back decades,” said UN Secretary General Ban Ki Moon before passage of the agreement. “The document with which you have just presented us is historic. It promises to set the world on a new path to a low emissions, climate-resilient future.”

The deal, known as the Paris Agreement, represents remarkable compromise after years of negotiations in which developing countries wrangled with their developed counterparts and failed to come to agreement on several key occasions. Supporters say the agreement will help define the energy landscape for the remainder of the century and signal to markets the beginning of the end of more than one hundred years of dependence on fossil fuels for economic growth

Observers had feared that a negotiated text could result in a lowest common denominator to meet the differing needs of all the parties present in Paris. But climate policy experts appeared largely satisfied with the draft adopted Saturday at the Le Bourget Airport just outside of Paris.

A strong long-term goal to reduce carbon emissions, provisions explaining how developing countries will receive financing for their efforts to adapt to climate change, and a transparency system to ensure that countries meet their promises to reduce greenhouse gas emissions were among those key goals. The text includes provisions addressing all those key points.

The agreement includes a long-term goal of holding global temperature rise “well below” 2°C (3.6°F) by 2100 and recognizes a maximum temperature rise of below 1.5°C (2.7°F) as an ideal goal. The 2°C target is needed to avoid the most devastating effects of climate change, according to climate scientists, but it would not be enough to save many of the world’s most vulnerable countries. Those nations, largely small Pacific Island countries, launched a large-scale push for the more aggressive 1.5°C target to be included in the agreement. The draft text also calls for “global peaking of greenhouse gas emissions as soon as possible” and for the continued reduction of greenhouse gas emissions in the second half of this century as science allows.

Measures to finance efforts to fight climate change in the developing world had also been a key sticking point in negations. The agreement renews a commitment by developed countries to send $100 billion a year beginning in 2020 to developing countries to support their efforts to fight climate change. The deal describes the sum as a “floor,” which may presumably be increased.

The agreement also requires all participant countries to assess their efforts to reduce carbon emissions every five years and expand upon those efforts as they are capable. Some countries had previously expressed reluctance to promise to increase their goals so far in advance without knowing their economic situation.

The responsibilities of developed countries are distinguished from those of their developing counterparts throughout the text, a key demand of large developing countries like India and China that worried the agreement might require them to take actions that would slow their economic growth.

“It has all the core elements that the environmental community wanted,” said John Coequyt, the Sierra Club’s director of federal and international climate campaigns.

Do You Live in a Climate Change Hotspot?

Spaceborne Carbon Counter Map

Nearly half of all human carbon dioxide emissions are absorbed by plants, and NASA is monitoring this absorption.

Carbon dioxide or CO2 emissions into our planet’s atmosphere is causing climate change — a major problem that humans need to tackle and adapt to.  It is leading to warmer atmospheric temperatures, warmer and more acidic oceans, rising sea-levels, and changing and extreme weather patterns.  Although nations across the globe have committed to reducing carbon emissions, emissions will not slow in the near future, and CO2concentrations will continue to rise.

An alarming fact is that CO2 concentrations are the highest they have been in 400,000 years, and we are on track to cross the CO2 threshold of 400 parts per million (ppm).  This threshold does not mean there is going to be a climate catastrophe, but it does signal the importance of fighting climate change and how government inaction has only lead to worsening global impacts.

Luckily for us, CO2 concentrations would be much higher if it were not for plants that absorb nearly half of all human emissions each year.  NASA is very interested in this part of the carbon system and is now monitoring and tracking the absorption of CO2 by the land and ocean.

“Some years, almost all of it stays in the atmosphere and some years almost none of it remains in the atmosphere.  So in those years it must be absorbed into the ocean and land,” said Mike Freilich, the head of NASA’s Earth Science Division.

 

NASA scientists have been tracking CO2 movement using models and satellites such as NASA’s Orbiting Carbon Observatory-2 (OCO-2).  “OCO-2 gathers 100,000 high quality measurements of CO2 across the globe daily,” said Annmarie Eldering, deputy project scientist of OCO-2.  The instruments used on the satellite are so sensitive that they can detect changes as small as 1 ppm over any location, allowing scientists to determine potential COhotspots.

For example, data from OCO-2 shows that there has been more CO2 over the tropical Pacific Ocean since the spring.  Scientists are unsure if this is related to our current El-Niño which is known for creating above average ocean and atmospheric temperatures, but the results are different from previously collected data.

Why is it so important to monitor and track this absorbed CO2?  Not only will it help scientists understand how the absorption of CO2 by plants may change with a changing climate, according to Lesley Ott, a NASA research who works on the carbon modeling, “The motivation of all of this is to make models better and predict how the carbon cycle is going to change over the coming years.”

The problem of climate change can no longer be ignored, and improved CO2 modeling will hopefully influence policymakers to make scientifically-informed decisions to protect our planet for generations to come.

THIS OCTOBER SMASHED TEMPERATURE RECORDS AROUND THE WORLD

October

 

A map of temperature anomalies during October. Red shows the biggest deviation from the standard (temperatures recorded between 1951 and 1980).

If you’ve been wondering why your coats stayed in the closet and your heater remained off for the first part of fall, wonder no more. This October was the warmest on record. Ever.

Last month beat out all the other Octobers to get the title of hottest Octobersince record-keeping began in the late 1800’s. It was also the highest deviation from ‘normal’ global temperatures. Those temperatures were recorded between 1951 and 1980, and are averaged to get a general baseline. The data comes from NASA’s Goddard Institute for Space Studies, which looks at temperature changes over long periods of time (decades as opposed to days).

If it sounds like a familiar story, that’s because it is. Last winter was one of the warmest on record, even with all the snow. 2014 and 2012 were also record-breaking years, and with the addition of October to its already hot lineup, 2015 is likely to surpass both.

Extreme heat is now 4 times more likely than it was before the industrial revolution, and that shows no signs of stopping.

NASA: Sea Level Rise Is Going To Get Much Worse

Flooded Streets

Flooded Streets

New York City streets after Hurricane Sandy hit the city in 2012. Flooding like this could become more common in the future as sea levels rise.

Eleven of the fifteen largest cities in the world are located on the coast. The tenuous barrier between land and sea was a boon for humanity in the past, providing access to ports around the globe, building lifelines of trade between countries, and raising triumphs of steel and concrete high into the air. Now, sea levels are also on the rise, putting millions of people who live in those cities in harm’s way.

NASA released new estimates this week, finding that sea levels will probably rise about three feet sometime in the not-too-distant future, driven by melting glaciers and warming water.

“Given what we know now about how the ocean expands as it warms and how ice sheets and glaciers are adding water to the seas, it’s pretty certain we are locked into at least 3 feet of sea level rise, and probably more,” Steve Nerem, leader of the Sea Level Change Team said in a press release. “But we don’t know whether it will happen within a century or somewhat longer.”

To put that into perspective, NASA estimates that since 1992, sea levels have risen by about 3 inches.

Adding to the uncertainty over time, the Earth is not a perfect sphere, and variations around the globe mean that sea level change isn’t evenly distributed around the globe. In some places, sea level rise far exceeded the 3 inch average, going up by nearly 9 inches.

To help people really picture how sea level change could vary around the world, NASA put together this short video showing how, even though there are a few areas where sea level is actually dropping, over the vast majority of the world, sea level is going up.

Sea level rise will be felt most harshly along the coasts, where large population centers are already having to prepare for more flooding every time a storm rolls in. Already, flooding in coastal cities costs $6 billion every year. By 2050, that number is expected to reach $1 trillion.

NASA scientists will continue to keep track of sea level rise using numerous satellites, boats, underwater drones, submarines, and a program aptly titled OMG (Oceans Melting Greenland).

In the meantime, low-lying areas from Florida to Boston are pondering infrastructure solutions, and New Orleans, recognizing the 10 year anniversary of Hurricane Katrina this week, just released a plan to make the city resilient in the face of future storms.
