世界需要可持续、高效和可再生的能源生产。我们提出了植物微生物燃料电池（植物-MFC），这是一种原位利用生物能源的概念。在植物-MFC中，植物和细菌将太阳能转化为绿色电力。主要思想是植物产生根沉积物，主要以碳水化合物的形式，细菌通过燃料电池将这些根沉积物转化为电能。在这里，我们演示了使用芦苇甘草的原理证明。我们实现了阳极表面 67 mW m(-2) 的最大发电量。该系统的特点是：（1）无损、原位采集生物能源； (2) 可以在湿地和贫瘠土壤中实施，无需与粮食或传统生物能源生产竞争，这使其成为额外的生物能源供应； (3) 欧洲预计潜在发电量为 21 GJ ha(-1) 年(-1) (5800 kWh ha(-1) 年(-1))； (4) 碳中和和无燃烧排放运行。版权所有 (c) 2008 John Wiley & Sons, Ltd.
The world needs sustainable, efficient, and renewable energy production. We present the plant microbial fuel cell (plant-MFC), a concept that exploits a bioenergy source in situ. In the plant-MFC, plants and bacteria were present to convert solar energy into green electricity. The principal idea is that plants produce rhizodeposits, mostly in the form of carbohydrates, and the bacteria convert these rhizodeposits into electrical energy via the fuel cell. Here, we demonstrated the proof of principle using Reed mannagrass. We achieved a maximal electrical power production of 67 mW m(-2) anode surface. This system was characterized by: (1) nondestructive, in situ harvesting of bioenergy; (2) potential implementation in wetlands and poor soils without competition to food or conventional bioenergy production, which makes it an additional bioenergy supply; (3) an estimated potential electricity production of 21 GJ ha(-1) year(-1) (5800 kWh ha(-1) year(-1)) in Europe; and (4) carbon neutral and combustion emission-free operation.
