Understanding the IPCC’s Devotion to Carbon Capture

P1130803-3I’ve delivered several dispatches on carbon capture and storage (CCS) recently, including a pictorial ‘how-it-works’ feature on the world’s first commercial CCS power plant posted this week by Technology Review and typeset for their January print issue. Two aspects of CCS technology and its potential applications bear further elaboration than was possible in that short text.

Most critical is a longer-term view on how capturing carbon dioxide pollution from power plants (and other industrial CO2 sources) can serve to reduce atmospheric carbon dioxide concentrations. Continue reading

The Inconvenient Science of Biomass Power

New science confirms that burning trees to produce power instead of coal may be a losing strategy for combatting climate change.

In my April 2012 Spectrum news article on the questionable carbon benefits of largescale biomass power generation, I identified a boom in exports of wood pellets from the U.S. Southeast to Europe, where they are fast becoming a crucial energy supply for power firms seeking to meet the European Union’s renewable energy and carbon reduction mandates.

Forbes Magazine greentech columnist (and friend) Erica Gies noted my analysis in a May 22 blog post, Massachusetts Addresses “Biomass Loophole” and Limits Subsidies, about recently-issued regulations that set higher standards for biomass power plants seeking state-issued renewable energy certificates.
