Best Available Technologies (BAT) for On-Site Electricity Generation for nZEB
In addition to the large scale power plants presented in Chap. 2, there are several technologies for dispersed or in situ generation of electricity. In general these technologies use local renewable energy sources in the form of solar and wind energy or biomass. Small scale hydropower plants are a highly efficient technology with high durability and low maintenance costs; nevertheless, they will not be presented here because these devices are only useful for near-by electricity generation. Fossil or gaseous biomass fuels can be used for electricity generation on-site with the combined generation of heat and electricity. As an emerging technology, hydrogen driven fuel cells will also be presented in this chapter.
