Map Of Potential Carbon Dioxide Storage Sites In U.S. Sedimentary Basins

via Nobel Intent:



Potential carbon dioxide sequestration sites are shown in blue.

Carbon capture and sequestration (CCS) is a climate change mitigation measure. Carbon dioxide emitted by power plants is compressed into a supercritical fluid and injected in deep saline aquifers with an impermeable geological capping layer that prevents the liquid CO2 from escaping.

Does U.S. sedimentary basins have enough storage capacity to make a difference in emissions? From the abstract published in PNAS:

We show that in the United States, if CO2 production from power generation continues to rise at recent rates, then CCS can store enough CO2 to stabilize emissions at current levels for at least 100 y.  This result suggests that the large-scale implementation of CCS is a geologically viable climate-change mitigation option in the United States over the next century.

Will it be economically viable though? There seems to be no hurry in the climate change policy environment in making CO2 emissions expensive enough for companies to turn to CCS.

Hiding Behind Per Capita Emissions Doesn't Make Us Cleaner Than West

I wish India emitted a lot more CO2 and its per capita emissions were comparable to the developed nations.

I say this because I get mad reading headlines like this one in Indian newspapers:

Greenhouse emission numbers out and we're cleaner compared to West

The article uses our low per capita emissions as an indicator that our economy is cleaner than the West. That is misleading. Take a look at energy sources and how efficiently we use that energy. Here is a graphic which compares India's energy intensity (efficiency) and fuel mix with other major emitters. We compare poorly with the West and most other developed nations when it comes to energy efficiency and we use similar proportions of dirty energy sources as most other countries.

We emit less both absolute and per capita because of widespread poverty and huge energy shortfalls..because of energy required but not produced.

Hundreds of millions of people live subsistence lives and hundreds of millions more have a low energy footprint. These people have minimal access to energy and no amount of spin doctoring numbers about per capita emissions vs absolute emissions should be allowed to hide that fact. The media needs to keep hammering away at this reality and not write self-congratulatory articles on our low per capita emissions as if that is something to be celebrated.

In fact, there is absolutely nothing to celebrate in our current emissions profile.  Less per capita emissions is a reflection of a large poor population and not a clean energy economy.

I wish that for once our politicians will look us in the eye and admit the real reason for our low emissions instead of making pompous pronouncements on per capita emissions and I wish our stupid media looks beyond these exaltation's  and not get hoodwinked into giving comforting news bytes about being "cleaner" than the West.
