Bio-energy with carbon capture and storage (BECCS) is an unrealistic pipe dream that was part of the COP21 agreement. It is a multi-faceted technology that has not been tried out and it is assumed it could be deployed on a massive scale within 35-years and sustained for many decades after that. The target date of 2050 is unrealistic since Anthropogenic Climate Disruption (ACD) effects are happening so rapidly that the collapse of industrial civilization is likely to take place long before that target date is reached. The underground storage efforts began about two decades ago and have not shown the promise that was expected. Finally, numerous studies have shown that many plants, grown under natural conditions do not fare well under conditions of increasing drought, increasing CO2 concentration above certain levels and increasing temperatures. Links, to articles on this last issue, follow. Typically, these issues have not been included in hopeful presentations on the viability of BECCS.

It would be wise to also consider past technologies that were once considered quite hopeful but which turned out to be great embarrassments. One example was the U.S. program called Project Plowshare that had it’s equivalent in the Soviet Russia. The program involved employing nuclear explosives for various civil engineering projects.
