WEBINAR: Boosting hydropower with good practices for research

 Get ready for the upcoming webinar featuring three newly EU-funded projects along with ETIP Hydropower next 21 May 2024 (13:30 – 15:00 CET)!

Europe has significant hydropower potential due to its diverse altitude landscape and surrounding seas. However, only a small fraction (13.8%) of the EU's net electricity generation comes from hydropower plants. This low utilization is primarily attributed to inadequate digital management, handling, and maintenance of hydropower plants compared to other energy generation methods.

In the webinar, the following projects will be presented:

Katerina DRIVAKOU (Technical Coordinator, UBITECH) will talk on behalf of D-HYDROFLEX, a project that aims to develop a toolkit for digitally renovating existing hydroelectric power plants based on sensors, digital twins, AI algorithms, hybridization modelling (power-to-hydrogen), cloud-edge computing, and image processing. Validation will take place in 7 hydro plants across Europe, addressing challenges posed by the European Green Deal and the Digital Decade Policy Programme 2030.

Alkiviadis TROMARAS (Project Coordinator, CERTH) will represent Di-Hydro an initiative that aims to digitize hydropower plants by developing smart devices and data acquisition techniques. Digital twins will facilitate real-time data exchange, enabling optimal coordination of power generation considering societal, weather, water flow, environmental, and biodiversity data.

Aonghus MCNABOLA (Project Coordinator, Trinity College Dublin) will speak for iAMP-Hydro, a project that focuses on developing digital solutions to address the evolving needs of the EU hydropower sector. With a significant portion of hydro generation assets slated for potential upgrades by 2030, the project aligns closely with energy sustainability and digital transformation imperatives. By harnessing the collective capabilities of diverse partners, iAMP-Hydro seeks to unlock pathways for optimizing asset performance, minimizing environmental impact, and fostering socio-economic development in communities served by hydropower facilities.

In addition, we will count on the presence of Emanuele Quaranta who will provide the audience with an overview about research for hydropower on behalf of the European Commission. Anton Schleiss, as technical coordinator, will represent ETIP HYDROPOWER during the session.

IHA's blog on Drought Management

The International Hydropower Association (IHA) recently released a blog titled "Drought Management: The Functions of Hydropower." While climate change projections suggest increased risks for hydropower as temperatures rise, the blog emphasizes the unique role hydropower infrastructure can play in mitigating drought impacts.

According to the IHA, even though droughts can affect hydropower generation, reservoirs associated with these projects offer crucial capabilities:

  • Basin Resilience: Reservoirs can store water during wet seasons, creating a buffer during dry periods. This stored water can then be released to maintain water flow in rivers and maintain critical ecological functions.
  • Socio-Economic Benefits: During droughts, hydropower can continue to generate electricity, providing a reliable source of power for homes, businesses, and vital infrastructure. This helps maintain economic activity and social well-being even during dry spells.

The blog highlights the economic significance of hydropower's role in drought mitigation. Moreover, a previous assessment estimated the combined annual economic benefits of hydropower's flood and drought control functions globally at a staggering 314.88 billion USD, representing 0.35% of global GDP.

A RESEARCH IMPERATIVE IN THE FUTURE OF HYDROPOWER

In response to the European Commission’s Calls for enhanced flexibility, storage, and environmental sustainability, ETIP Hydropower is paving the way for the transformation of the energy landscape

 

For more than a century, hydropower has served as a reliable and clean energy provider, harnessing the power of water to generate electricity. Its historical significance and proven results make it a crucial element in the global pursuit of more sustainable energy alternatives. The European Commission (EC) is aware of this role and has placed in the spotlight this renewable source.

The EC acknowledges the ability of hydropower in enhancing flexibility, storage capacity and sustainability. The Calls for proposals in these areas reflect the need for adaptation to changing energy demands that require improved grid stability. The European Technology and Innovation Platform (ETIP) Hydropower emerges as an ally in this quest as its main objective is to gather all the stakeholders in the hydropower value chain and guide them towards the innovations required to align with the European vision.

 

Harnessing Research in the hydropower sector

ETIPs collaboration with EC Research and Innovation initiatives becomes essential in shaping the future of energy. These projects act as catalysts for development as they create the base for exploration and implementation of future solutions. In this setting, every ETIP establishes a strategic roadmap for stakeholders from research communities and beyond.

In relation to hydropower, efficiency, sustainability, flexibility, and storage emerge as the keywords of the EC’s vision for the sector in the coming years, providing a clear structure to navigate the research scene.

    • Efficiency:

This means to enhance hydropower efficiency for energy output. The projects in this category are usually infrastructure based, for example, they could tackle the modernisation of turbines or improvement of plants’ performance.

    • Sustainability:

Addressing historical environmental concerns, sustainability in hydropower is on the quest of improved models that can only be reached through investments in research and innovation. Actions in this research line include monitoring restoration sites, establishing biological databases, identifying reservoir services for biodiversity, researching environmental indicators, fostering eco-design collaboration, and exploring innovative societal approaches, among others.

    • Flexibility:

The ability of hydropower to adapt to fluctuating energy demands is one of the biggest assets, since it is essential to grid stability. Projects addressing flexibility mostly concentrate on the implementation of digital solutions, such as smart grid integration or smart storage systems.

    • Storage:

Storage is one of the biggest challenges across all energy transition efforts. It is essential to address the intermittent nature of renewable energy sources and to adapt to the demand. Research projects tackling storage revolve around developments in pumped storage and other technologies to store the excess of energy during periods of low demand. Large hydropower reservoirs are also vital to mitigate climate change effects and thus contribute to the WEF NEXUS and achievement of the SDGs of the United Nations.

 

By strategically associating these keywords (efficiency, sustainability, flexibility and storage) with EU research initiatives, stakeholders gain a powerful tool to navigate the research needs of the sector. This targeted approach ensures the alignment with the broader vision for energy that has been set up by the European Commission, making hydropower as not only resilient, but also an environmentally friendly and technologically advanced source.

As we embrace the challenges of energy transition, the synergy between research and innovation and policy emerges as a locomotive behind the progress of hydropower. The cooperation between the EC and ETIP Hydropower is more than just a connection. It could be an opportunity to steer hydropower as the pivot to catalyse energy transition in Europe.
