Hydropower: How to avoid potential pollution by innovation
Partner Event at the EU Green Week 2021
PARTNER EVENT AT THE EU GREEN WEEK 2021
Theme: Hydropower: how to avoid potential pollution sources and to mitigate environmental impacts by innovative measures and concepts?
Type of event: A roundtable discussion preceded and motivated by a keynote as well as short statements from experts
Target audience: NGOs, policymakers, public, academia, hydropower industry, stakeholders involved in the SET-Plan
Hydropower and energy transition
Hydropower already plays an important role today, and will become even more important in the coming decades, since hydropower can be a catalyst for the clean energy transition.
The ambitious plan for energy transition in Europe seeks to achieve a low-carbon climate-resilient future in a safe and cost-effective way, serving as a worldwide example. The key role of electricity will be strongly reinforced in this energy transition. In many European countries, the phase out of nuclear and coal generation has started with the transition to new renewable sources comprising mainly of solar and wind for electricity generation.
However, solar and wind are variable energy sources and difficult to align with demand. Hydropower already supports integration of wind and solar energy into the supply grid through flexibility in generation as well as its potential capacity for energy storage. These services will be in much greater demand in order to achieve the energy transition in Europe, and worldwide.
Hydropower, with its untapped potential, has all the technical characteristics to serve as an excellent catalyst for a successful energy transition. However, successfully increasing efficient and flexible hydropower production, to complement wind and solar energy production, will require a more environmentally and socially acceptable approach based on innovative concepts and mitigation measures.
Potential pollution sources and environmental impacts of hydropower
Looking at pollution in a narrow sense, one may recognize that this is not the main problem and challenge for hydropower deployment. Nevertheless potential pollution sources have to be avoided in a hydropower project from the design to construction to operation to refurbishment and finally decommissioning by the timely implementation of protection and mitigation measures.
The main challenge is how to handle harmful environmental and socio-economic impacts, which may be seen as a “pollution” in a wider sense. Hot topics like biodiversity, river continuity and sediment dynamics, aquatic and terrestrial ecosystems, land use and landscape, amongst others, have to be addressed with innovative concepts and mitigation measures during the whole lifecycle of a hydropower plant. Furthermore, wide acceptance can often be achieved only within the framework of multipurpose projects which create a ‘win-win’ situation for all stakeholders and which have to be involved from the early design stages. Finally benefit sharing with local communities is also an important issue.
About the Roundtable
At the EU Green Week 2021, HYDROPOWER EUROPE aims to organise a Partner Event raising the issue of how to avoid potential pollution sources and to mitigate environmental impacts through innovative measures.
Around this question, the roundtable will openly discuss the challenges regarding potential pollution in a narrower sense and environmental as well as social-economic impacts in a wider sense.
Consequently, by sharing the interdisciplinary experience of the participants through discussion, this should highlight good practice and approaches which will help to avoid terrestrial and aquatic pollution and help mitigate harmful impacts. The roundtable will further consider how innovation can eliminate and/or reduce these sources of pollution and impacts.
The objective of this roundtable is also to make a contribution to improving the quality and the continuity of European rivers and to shed light on good practice that should serve as the basic standard for hydropower deployment.
The outcomes of the roundtable discussion will also provide a rich source of ideas and suggestions for the Hydropower Europe Forum to consider when finalizing its main documents, which comprise the Research and Innovation Agenda and Strategic Industry Roadmap for hydropower in Europe.
The roundtable discussion shall bring together NGO representatives, academia, major utilities, policymakers, and the wider audience including consumers and future entrepreneurs working on a transition towards a clean energy society.
