Press information: 300th PlanET plant starts operating
PlanET's substrate concepts achieves optimum gas yields
PlanET Biogastechnik GmbH recently has assessed the new orders from the past year in order to identify the substrate concepts with the highest yields. The result: Those who started out with biogas production using lots of cattle slurry, manure or grass, made clever use of fed in tariffs in Germany to their benefit, and kept enough gas storage on hand to enter into control energy in the following years. The substrate concept of the 300th PlanET biogas plant also fits precisely into this empirical pattern.
Individual substrate concepts with high percentage of slurry
Christoph Kleverth, director of PlanET’s German sales division, has gone to the trouble of assessing the individual substrate concepts of PlanET’s national new customers of 2012 at the beginning of 2013. His summary: “Those with substrates from input material remuneration class II should take action now instead of waiting. 100% slurry plants almost always pay off, regardless of the performance class,” according to the expert. “For instance, we have customers who have been running their 340 kWel CHP unit with 25,000 tons of cattle slurry for just 4,500 operating hours and will be receiving a so called “flexibility bonus” by operating their plant dependent on demand. Substrate concepts that have already paid off well in 2012 will enjoy major success in 2013,” Kleverth predicts.
30 percent energy crops achieves optimum gas yields
The 300th PlanET biogas plant also shows that even in regions with a high rate of livestock farming, there are still biogas concepts that pay off very well. 5,100 tons of cattle slurry and 2,900 tons of manure make a total of 66 percent of the substrate. Like nearly all successful substrate concepts in 2012, virtually no new plants even come close to the limit of 60 percent of maize input (according to the German law) and still achieve optimum gas yields. After all, only 30 percent renewable energy crops are enough to produce nearly 70 percent of the energy. PlanET’s winning concepts are sustainable, conserve resources, and have gained socio-political acceptance. Christoph Kleverth hopes that the use of manure and slurry will solidify into a trend soon. “The technology has advanced enormously; never before have farmers been so free in their choice of substrates”, the expert underlines his expectations.
