Negative emissions – a positive post!

From Grist an up-beat positive article on currently available methods to remove carbon – negative emissions! I understood that in order to reach Paris agreement, negative emissions will be required globally and in material fashion. This is the first post I’ve seen on an available method today – just some good ol’ fashioned wherewithal to make it happen is needed.

Quote:

A report recently published by the Lawrence Livermore National Lab, Getting to Neutral, suggests that power plants across the state could profitably convert wood from forests and orchards into liquid or hydrogen fuels, all while capturing their carbon.

“This isn’t predicated on any technological breakthroughs, said George Peridas, a scientist at the lab and an author of the report. “It’s all available today, it’s just a question of getting it to the cookie-cutter [mass production] phase.”

The idea, which often goes by the awkward acronym BECCS (bioenergy with carbon capture and storage), relies on the fact that trees soak up carbon dioxide from the atmosphere and store it in their tissues. Burn them while capturing their carbon and you’d have an energy source that was removing greenhouse gases: voila, so-called negative emissions. Harvest trees sustainably, so that they are naturally reseeded, or replanted in orchards, and you have what starts to look like a long-term solution.
