        This very brief white paper illustrates why all countries, states, or provinces that are serious about lowering carbon emissions in the power generation sector should include the use of pellets as a replacement for coal in their portfolio for renewable generation.


        FutureMetrics has published numerous white papers over the years about the efficacy of including pellet co-firing or full-firing in the menu of solutions for reducing CO2 emissions in the power sector.



        FutureMetrics’ white papers have also shown why pellet fuel is a low carbon solution. This short paper shows a real-world example of how pellet fueled pulverized coal power stations can be part of the solution.



        The chart below is from this past week and shows the generation mix in England.


        Currently, most of the power generated from pellets in the UK is by Drax Power. The Drax power station has six 645 megawatt units. Four of the six units are fully converted to use wood pellet fuel. The 396 megawatt Lynemouth power station has also been converted from coal to pellets.



        In the chart above one can clearly see how the wind (light green) did not blow early in the week and, of course, the sun (yellow) never shines at night. Furthermore, power generation by pellets is taking some of the peaking load which lowers the need to use the coal and natural gas.


        來自阿格斯(Argus Direct)2018年10月25日資訊:與去年相比,英國強勁生物質電力輸出減少了一些聯合循環燃氣輪機(CCGT)的輸出,而英國公用事業公司Drax在高峰負荷時間內一直在提高電力輸出獲取更高的價格。本月到目前為止,生物質電力輸出平均為2.3GW。

        From Argus Direct on October 25, 2018: Strong UK biomass output this month has pushed some combined-cycle gas turbines (CCGTs) out of the generation mix compared with last year, and UK utility Drax has been ramping up output during peak-load hours to capture higher prices. Biomass output has averaged 2.3GW so far this month.

        由于645MW Drax機組和396MW Lynemouth發電站從煤炭到生物質的轉換,生物質裝機容量同比增加約1.1GW,總容量達到3.2GW左右。

        Installed biomass capacity is around 1.1GW higher year on year because of the conversion from coal to biomass of the 645MW Drax unit 4 and the 396MW Lynemouth plant, taking total capacity to around 3.2GW.



        Output from CCGTs has averaged 12.4GW, down from 13.5GW in October 2017.



        This clearly demonstrates that using renewable low-carbon pellet fuel for power generation provides reliable on-demand baseload and peaking capacity.



        This strategy is the only pathway for generating renewable thermal power that does not suffer from uncontrolled variability and intermittency.
