Transmat World: CO2 sequestration

What Do We Do Now That We Know Climate Change is Inevitable?

Climate change experts say global emissions of CO2 must be reduced to 45% from 2010 levels by 2030. It must reach a “net” zero” level by 2050 in order to limit warming to 2.8 degrees Fahrenheit (1.5 degrees centigrade). The goal was originally set at 2 degrees centigrade (3.6 degrees Fahrenheit), but the Paris negotiations changed it to 1.5 degrees C. to appeal to a broader base of nations. This half degree means 10 million fewer people are displaced by the ocean’s rising, a 50% reduction of people experiencing water shortages around the globe, 50% reduction in species losing half their habitat, and a 80–90% destruction of coral reefs instead of 100%. The level of atmospheric CO2, however, has risen from 387 ppm in 2010 to 413 ppm in 2019, a 6.7% increase.

For the first time, Saudi Aramco revealed its finances publicly. Although it was April 1, this was no April Fool’s prank. The company made $111 billion last year, twice as much as Apple, the most profitable public company in the world. ExxonMobil made $20.8 billion. Royal Dutch Shell made $23.4 billion. The financial inertia of the fossil fuel industry is making a mockery of world climate goals. It is not just the fossil fuel industry but the industries it fuels as well. Trucking, shipping, airlines, auto, steel and concrete industries must all switch to electric or hydrogen by 2050 for “net zero” to happen. That’s 31 years away. Can you see all of these industries making the staggering commitments necessary to switch over without laws in place to make them? Can you see all 195 countries on Earth passing laws to force them to do this? It is not going to happen.

If CO2 levels rose 6.7% from 2010 to early 2019, it’s safe to say that by sometime in 2020 it will be an even 7% for the decade and the CO2 level in Jan. 2020 will be 420 ppm, 449.4 ppm in 2030, 480.9 in 2040 and 514.6 ppm by 2050. This does not take into consideration the positive feedback loops evaporating mass quantities of natural gas (methane) into the atmosphere from melting permafrost. Methane is 21 times better at warming the atmosphere than CO2. The hotter it gets, the more methane injected into the atmosphere and so on.

So what would more than 2 degrees centigrade do in terms of damage to the world? It could kill 50–80% of the fish in the oceans. Ice melting could raise sea levels by more than three feet by the end of the century. If Greenland and Antarctic ice eventually melts, it could raise oceans 230 feet. While it is doubtful this could happen on Earth, positive feedback loops and runaway greenhouse gasses created the hellish conditions seen on Venus.

That is not going to happen on Earth. As soon as the general population realizes fossil fuel companies have been gas lighting (no pun intended) them for decades, it will become possible to overcome their propaganda efforts and the legalized bribery our congressmen and senators disingenuously call lobbying. By 2050, strict environmental laws will force the fossil fuel industry to change or die. Don’t feel sorry for them. They will build a lot of renewable energy plants and CO2 sequestration plants and still be making money. Taxes will have to go up to pay for research on how to do this. The U.S. saw marginal rates of around 70% to 92% from 1950 to 1981. When you hear rich people complaining nowadays about taxes, take it with a grain of salt. They will be bitching until it’s zero.

The political process will be too slow to mediate the effects of climate change. We must develop a slew of technologies and social standards to counter this lack of social progress.

1. Carbon dioxide sequestration and other technologies actively removing CO2 must be developed and implemented. Carbon dioxide removal (CDR) technologies are already being developed, but more work must be done to make it economically viable.

2. Reforestation must take place on a grand scale. This will assist in carbon capture and restore habitats to insects and animals.

3. Cheap water technology will need to be implemented to offset the increasing scarcity of potable water.

4. We must find a way to capture energy from low temperature heat from industrial processes and server farms. This is a huge inefficiency in our global society.

5. Grants and prizes must be increased for the development of new technologies to mediate and reverse greenhouse gas levels.

6. Products will have to be designed to be recycled with the least amount of energy possible.

Our social evolution must strive to keep up with technology. Stringent laws concerning carbon output must be enacted on industry and society. One half of the population acting as if nothing is wrong and living a huge carbon footprint is not going to work.

It is a sad commentary on humanity that the captains of the industries that have taken us so far so fast would play chicken with a world threatening event. It is our responsibility as citizens of this world to reign them in and redirect their efforts to the common good. The only way to do this is to change our leadership by any means, preferably democratic, to people that are clear-headed, logical, moral, and responsible enough to lead us successfully through this age of salvation and into a brave new society of technological marvels in balance with the natural world.

Our modern lives insulate us from and make us forget a knowledge that came simply and unforgettably to our hunter-gatherer forebears. That is the discrimination between needs and desires. We don’t need smartphones, automobiles, TV, indoor plumbing, granite countertops, Nikes, non-fat lattes with caramel drizzles, YouTube, scented candles, or video games. We do need food, air, water, a modicum of shelter, and a proper temperature range in which our species can exist. The last was a given until recently. That’s why there’s no life on Mars or Venus—too cold, too hot. The fact that temperatures go up in lockstep with CO2 levels now makes CO2 capture and sequestration mandatory to provide us with one of our necessities, a livable temperature range.

If you want to make a lot of money, figure out a cheap way to remove CO2 from the atmosphere and stash it somewhere for several hundred years or forever. Everyone will thank you and shower you with cash. Ahahaha! That’s not true, but it should be true. Unfortunately, Trump is gutting U.S. funding for research in this area. That leaves the Chinese as the world leader for this technology. At the rate CO2 levels are increasing, we may end up renting the technology from them. Ironic, since they probably stole the idea from us to begin with.

Since energy companies revealed they are spending 5 trillion dollars over the next decade for fossil fuel exploration, it is a foregone conclusion that CO2 capture and sequestration (CCS) will be a technology of existential necessity. The fossil fuel industry has an enormous cache of wealth acquired at the expense of the Earth’s climate. They are going to use that wealth to continue doing what they do by gaming the legalized bribery system at the heart of many of America’s problems—lobbying. The energy companies plan to sell combustibles until fossil fuels are gone, they are too expensive to extract at a profit, or their client base has plummeted due to “natural causes.”

We are currently at 413 ppm CO2. We are on track to hit 550 ppm by end of century. This will raise average temps 10.8 degrees Fahrenheit. At some point in the next century, if we keep going at our current rate, we could see 700 to 900 ppm CO2, something not seen since the Eocene some 50 million years ago. Temperatures were up to 25 degrees Fahrenheit higher on average. There was no ice at the poles, but probably alligators and palm trees in Antartica.

Looking at past geological records, it appears there is a lag time of one to four centuries for sea levels to catch up to rapid changes in CO2 levels. None have been as rapid as the last 200 years. We know that sea levels were a hundred feet higher during the Miocene, 15 million years ago, when CO2 levels were similar to what we have now. The reason we don’t see that large increase in sea levels or the 11 degrees F. higher temperature yet is because of the buffer provided by our still-cool, deep ocean waters. Ninety percent of the ocean is between 32 and 37.5 degrees Fahrenheit. But over the next couple of centuries we will see increasingly rapid elevations in sea levels and temperature.

If we burn the rest of our fossil fuels scientists estimate atmospheric CO2 levels could rise to 1000–5000 ppm. If it is toward the upper limits of this estimate, it is debatable whether life will continue as we know it on Earth. Before we get there fossil fuel companies will, hopefully, realize they could lose their customers and, therefore, make some changes. These same scientists say just 450 ppm will be disastrous. It is a certainty we will reach that. With uncontrolled fossil fuel use and no capture and sequestration, CO2 levels will easily blow past 500 ppm; and our civilization could collapse under the strain of drought, food chain disruption, defrosted pathogens, resource wars, heat prostration, and tropical diseases.

That is where CCS comes in. Various means of scrubbing CO2 from the air have been developed. It is then used for making lubricating oil and putting the fizz in soda water. Those are pretty small markets for the amount of CO2 we need to eliminate. Plus, who is going to pay for it on the industrial scale that is required. It would be ideal for those responsible for the CO2 in the first place to pay for capture and sequestration by implementing a carbon tax or a cap-and-trade scheme. Otherwise, we are simply paying to clean up the energy companies’ mess which, in the end, may not be out of the realm of possibilities.

In the past it was thought that CO2 capture would have to take place at those industries where it is produced—chemical, power, concrete, steel, and fertilizer plants. Then it would be pumped somewhere to be injected into the ground. This is very expensive and unlikely to be adopted.

A recently developed CCS technology allows carbon to be extracted directly from the air. Not oddly at all, it is called Direct Air Capture (DAC). With current technology it may be possible to get this down to about $100 dollars per ton. It needs to be ten times less expensive ($10 to $20 per ton) not to be a drag on the economy. This is the only technology that can realize a carbon negative offset. In other words, it could remove more carbon than is produced by mankind and nature to reduce overall levels in the atmosphere. The only alternative coming close is massive reforestation and afforestation. These have their own sets of problems and need funding to iron out the bugs.

The problem is money. No one except a few universities and Bill Gates are spending money in the U.S. to develop this technology. It is not enough that we strip carbon out of the atmosphere. It must be put in a stable environment or condition and left there for hundreds, if not thousands, of years. Turn it back into limestone? Make CO2-foamed concrete? Make plastic to feed our 3D printers? Plant all available land with trees? I don’t know. That is why we need some smart people working on this right away.

Environmentalists are in a moral tug of war about CO2 capture and sequestration. Some believe it will give the fossil fuel companies an incentive to keep on doing what they are doing. That ship has sailed. We cannot be picky now about how carbon is removed from the atmosphere. It is all good, but CCS offers at least the possibility to reverse the levels of carbon in the atmosphere, staving off the worst of global warning until the climate stabilizes at a reasonable temperature—one of the basic needs that will allow us to keep on drinking non-fat lattes with caramel drizzles.
