UK Sets Binding Carbon Cuts; Requires CCS at Coal Plants
The UK has all but doomed new coal-fired capacity by simultaneously setting binding carbon reduction goals and by requiring carbon capture and sequestration (CCS) of carbon emissions from new mid-size coal-fired power plants. Existing plants will also be required to retrofit their plants when CCS technology is demonstrated, now estimated to happen by 2020.

Auctioning Allowances Will Not Cut Carbon Emissions Faster
Utilities generally support a cap-and-trade approach to reducing carbon emissions—but only when the objective of any legislation is to promote cost-effective reductions. The least-cost alternative for consumers requires free distribution of all carbon allowances.

Commercial Experience with Concrete-Friendly Mercury Sorbents
Commonly, 20% of the cement (by weight) in a concrete mix is replaced by fly ash. Fly ash enhances the workability, durability, and ultimate strength of concrete at a lower cost than cement. However, mercury sorbents can change the ash properties to make it unsuitable as a concrete additive. New “concrete-friendly” sorbents can keep the revenues from ash sales flowing.

Better Combustion Airflow Monitoring at the Hunan Yiyang Power Plant
Measuring combustion airflow in a coal-fired power plant can be problematic when using annubar instruments that feature small holes that can easily plug with coal dust. Sierra Instruments eliminates this big maintenance headache with its more-accurate, nonplugging thermal mass flow meter design.

Of Prosperity and Pollution (supplement to Powering the People: India’s Capacity Expansion Plans)
Because India has large domestic coal resources (and virtually no other fuel sources); a strong incentive to deploy cheaper, well-proven generation technology; and needs to rapidly increase the availability of electricity to its citizens, the country will likely continue to rely on coal-based power in the long run.
