Climate Change Mitigation: Is it a Good Idea to Sweep the Carbon Under the Carpet?
Climate Change Mitigation: Is it a Good Idea to Sweep the Carbon Under the Carpet?
Above: our paper recently published in Nature Energy. Our conclusion is that, in terms of energy returns, renewable energy in the form of solar or wind is much better than carbon capture and storage for mitigating of climate change. Sweeping the carbon underground is not a good idea.
We have a little problem: for more than thirty years, the climate scientists of the International Panel on Climate Change (IPCC) have been telling us that if we don’t stop emitting greenhouse gases into the atmosphere — mainly CO2 — we are in dire trouble. And we have done very little, nearly nothing. As predicted, we ARE in dire trouble.
There is some element showing that things may change: the polls indicate that more and more people are starting to understand the mess we are in and the action of the young Swedish activist Greta Thunberg is making waves in the memesphere. We may be awakening from a 30 years slumber to discover that we have to hurry up and do something. But what?
Not that we lack plans: every IPCC report released includes plans on what we could or should do to avoid the worse. We have to follow a steep trajectory of de-carbonization while, at the same time, maintaining a vital minimum supply of energy to society. But how to do that?
The most common idea floated in these discussions is to use Carbon Capture and Sequestration (CCS). It is straightforward: instead of releasing into the atmosphere the CO2 emitted by a power plant, you pump it underground, sequestering it in a porous reservoir, maybe one that, earlier on, had contained gas or petroleum.

The $17.6 Trillion Solution To Climate Change
The $17.6 Trillion Solution To Climate Change.
This week, the world’s leaders are gathering in Lima, Peru for the UN Framework Convention on Climate Change, where they hope to put together a plan for cutting global emissions that will slow the inexorable warming of the planet.
The convention follows a deal reached last month by the United States and China – the globe’s top two polluters – to cut their emissions. For China, this means capping its emissions at whatever rate they hit in 2030, while the U.S. pledges to reduce its emissions by 26 to 28 percent of its 2005 levels by 2025.
Before we all stifle a yawn at the prospect of reading yet another treatise on the unlikelihood of the world actually agreeing to anything beyond a set of useless platitudes, know that there is another way of going about the reduction of carbon in the atmosphere, and that is carbon capture and storage.

CCS, as it’s known in the industry, involves sequestering waste carbon dioxide from oil and gas or coal mining operations, pipelining it to a storage facility, and then injecting the CO2 underground in order to prevent it from escaping into the atmosphere.
