摘要

Hydropower in Europe is facing a great number of challenges. To tackle these environmental, societal, technological and market challenges, the hydropower sector needs to find new approaches to future development in accordance with environmental and social demand. So where is hydropower, the world's largest renewable energy source heading in the foreseeable future? Predictions show that hydropower will hold the lead among renewable energy sources as the world's largest source of renewable electricity generation. Climate change will play a decisive role in the development of hydropower energy because of its threat to the entire hydrological cycle. Moreover, the hydropower sector will have to show its worth in dealing with continuous opposition from critics voicing concerns about the environmental and social damage caused by hydropower projects, as is also the case for other renewable energy sources (onshore and partly offshore wind, distribution/transmission grid projects).One of the avenues for the future sustainable growth for this sector lies in the development of run-of-river plants (as a less controversial type of hydropower plant) or in pumped-storage plants that benefit from a closed cycle, hence not interfering with natural water bodies. Furthermore, multipurpose storage power plants and reservoirs will become vital for the mitigation of climate effects such as droughts and floods. There is significant potential for increasing the volume of existing reservoirs through the heightening of dams. New large multipurpose reservoirs may be limited by environmental and socio-economic constraints, but by taking advantage of synergies, compromises may be found. Another avenue for development lies in the increasing digitalization of hydropower, with several hydropower plant operators using various Industrial Internet of Things (IIoT) technologies to make hydropower more efficient, cheaper and environmentally compatible. Hydropower delivers many services beyond just electricity supply, as an important player in both water resources management and water storage. This will be key in the near future because of climate change. However, regulation and remuneration play an important role in this future scenario because of their impact on hydropower revenues. Frequent alteration of regulations is indeed a factor that impacts negatively on the decision-making process for new hydropower projects, since it increases the risk of uncertainty in a sector that is already capital intensive and has a large market risk.
