Carbon capture and storage. Loved by some, hated by others, essential to many an energy transition modeller for achieving net zero emissions. On today's show we explore some of the science and engineering challenges underlying Carbon Capture and Sequestration (CCS.) We look at CO2 capture at the stack, from the air and oceans examining the technical possibilities, the energy and material costs and the scaling difficulties.

The history of human influence on the climate system is thought to predate the industrial revolution. For example the Little Ice Age is correlated to massive human population die offs and accompanying reforestation secondary to the Black Death and old world diseases running rampant in the Americas.

Since the industrial revolution the burning of fossil fuels has taken us from an atmospheric concentration of 280ppm to 417ppm of CO2 with an accompanying 1C increase in global average temperatures. The laws of thermodynamics make reversing our centuries long liberation of hundreds of millions of years of stored carbon unimaginably difficult.

Enslaving carbon by emitting a trillion tonnes of CO2 into the atmosphere to power an army of machines and chemical processes has brought humanity unimaginable wealth, freed slaves and extended lifespans but threatens future prosperity. Truly reverse engineering that process to put that CO2 back underground comes with a near impossible price tag, new infrastructure and energy requirements.

Keeping carbon in the ground and abating emissions as much as possible is an urgent matter however many environmentalists and climate activists chearlead the closure of zero emissions nuclear plants like Indian Point last week. An ounce of prevention is truly worth a pound of cure but in a global society utterly dependent on fossil fuels for energy, transportation, cement, steel, fertilizer and many other vital processes is CCS part of the solution?

I am joined by Sean Wagner a materials engineer with a masters of science in engineering focused on nanotechnology from the University of Alberta. Sean is a master science communicator and lead writer and editor at the Alberta Nuclear Nucleus, a co-founder of Canadians for Nuclear Energy and the lead science advisor for the Decouple Podcast.
