The Challenge

Context

Untapped Hydropower Potential in Low-Head Hydraulic Networks
There is an urgent need of exploiting the untapped potential of hydropower. New projects that are being planned in Europe or that are on-going mainly refer to conventional hydropower, but there is indeed a widely recognized untapped potential of water resources in hydraulic networks with low head, small reservoir/water body size and impaired water quality, such as water distribution networks, wastewater treatment networks, irrigation systems and free-flowing water streams.
Limitations of Current Conventional Hydropower Solutions
Conventional hydropower solutions (impulse, reaction and kinetic turbines) are characterized by high investment costs for energy recovery in non-hydropower hydraulic systems. Current hydropower technology is only suitable for hydraulic power greater than 15-20 kW.
Unlocking Cost Savings and Efficiency with Hydropower in Municipal Networks
As potential hydropower prosumers, municipalities and network owners may want to decrease the OPEX costs and/or improve the efficiency in the use of water/energy and hence the resilience of their network through realization of the untapped hydropower potential in various hydraulic systems.

The European Strategic Energy Technology Plan (Set Plan)

The European Strategic Energy Technology Plan (SET Plan) is a key stepping-stone to facilitate the transition towards a climate-neutral energy system through the development of low-carbon technologies in a fast and cost- competitive way. The climate-neutral energy system strategy will bring Europe in the leading position of being the first continent characterized by a complete decarbonized society in 2050. It is a matter of fact that to achieve such an ambitious goal, it is necessary to increase the share of energy production from renewable energy sources. Among renewables, one of the leading roles is certainly played by hydropower whose technology is facing a new boost in terms of innovation due to the new challenges posed by the Clean Energy Transition (CET).

To meet the ambitious goals posed by the Clean Energy Transition, hydropower growth is still expected in the future and, in particular, the upgrade and refurbishment of existing plants and the powering of non-powered dams or new stream-reach are primary goals. Small hydropower systems are increasingly considered an essential renewable energy source worldwide mainly because of their key advantages in terms of storage capacity and greater programmability in comparison with the other main renewable energy sources

Technology Readiness Level

H-HOPE will consist mainly of research and innovation activities focusing on progressing technological solutions (multi-disciplinary design approach + efficient, adaptive and low-cost PTO) to bring it from TRL 3 to TRL 5. In particular:

Advancing Technology Readiness Levels through Multi-Physics Design
The multi-physics design strategy and the experimental activities will bring the technology from TRL3 to TRL4
Moving to the Next Level: Validating Hydropower Technology in Real Operating Conditions
The full-scale experiments and the numerical validation in real operating conditions will bring the technology from TRL4 to TRL5.

Target Groups

Researchers

Researchers in a broad range of fields (social, economy, engineering), research alliances (EERA, IEA, etc.), technical experts in the industrial sector related to fluid and energy systems, scientific experts from the industry (mechanical, electric, civil, environmental management), company pre-development departments.

Technology/Service suppliers (industry) & users

SME, individuals, who build these systems and sell them to industrial alliances (Hydropower Europe, etc.), residential and commercial prosumers producing small amounts of power to remote sites without the need to stop/start device locally

Municipalities, private water supply operators

All operators, including water supply operators, policy makers, inspector bodies, investors, prosumers, general public and NGOs

Project Goals & Objectives

  1. Identify unrealised hydropower in non-hydropower hydraulic systems and in free-flowing water streams, understanding theoretical hidden hydropower potential (power, energy) estimation per region in the EU, identifying potential regions as well as exploring the potential for commercial and residential prosumers. 
  2. Develop H-HOPE technology of extracting energy from vortex induced vibrations by using an innovative multi-physics design strategy and an innovative PTO, increasing the efficiency and flexibility of the energy harvesting unit. This will be demonstrated for low head and small reservoir or water body size, while being low cost for economic viability and environmentally sustainable.
  3. Implementation of state-of-the-art measurement and testing infrastructure to test demonstrators in relevant environments (wastewater, fresh water, impaired water quality, etc.) and in different sectors, improving the capacity of hydraulic laboratories.
  4. Set up a H-Hope platform for sharing all scientific background, technical details, design plans and instructions to individual users, individual and commercial prosumers – enabling bottom-up CET, improving RES penetration, and adhering to EU goals on CO2 reduction and to bring together industry, politics, researchers and stakeholders from EU regions to promote new hydropower technologies, focusing on renewable prosumers in particular.
Outcomes

1) Advance European leadership 

Advance the European scientific basis, leadership and global role in the area of sustainable hydropower 

2) Additional sustainable hydropower 

– create additional sustainable hydropower capacity to the existing fleet, maintain and advance European technological competitiveness in the sector, thus supporting the EU goals for climate protection, energy independence and economic growth 

3) Enhanced water supply systems 

Enhance sustainability of added hydropower capacities by addressing social, economic and environmental aspects and by promoting prosumer renewable energy in cities and communities. 

Impact

The H-HOPE hydropower technology will allow to tap the huge potential of EU hydropower hidden in hydraulic systems. It will reduce the cost and improve efficiency of renewable energy and their value chains, potentially de-risking renewable energy and fuel technologies with a view to their commercial exploitation. 

H-HOPE will facilitate the integration of renewable energy solutions in decentralized and remotely placed energy consuming areas and making the water networks more resilient, reinforce the European scientific basis, produce electricity in remote areas of cities and communities as well as in remote infrastructures, allowing a progressive digitalization of these areas/infrastructures. The resulting real-time operation will increase the resilience of these areas.

H-Hope will set the stage for a market of Energy Harvesters, which will digitalize remote dispersed sensor networks, allowing real-time monitoring, reducing maintenance costs and improving management. As a result, managers will also be able to operate their water and energy systems more efficiently, potentially saving energy and costs.

The Solution

Bringing State of the Art Technology for the Hydraulic Network

H-HOPE Technology

Case Studies

Eight case studies, located in six European countries (Figure 9) will provide real operational data to the H- HOPE project. These case studies represent all the targeted applications of the H-HOPE technology: freshwater supply network, wastewater network, large water streams, hot water supply network and lagoon flows. Data will be properly post-processed to be used in the design strategy of the technology.

DIY Platform

H-HOPE derived devices computer-aided design (CAD) models will be converted and saved in the stereolithography file format (STL), an actual CAD file format for additive manufacturing. The STL files will be further processed by slicing software, converting a 3D model into thin layers into G-code for several most often used types of 3D printers – making 3D models of H-Hope devices ready to be printed from polymeric materials.
H-HOPE will address manufacturers to participate in the platform exploitation through selling their components or services through the DIY platform. Furthermore, the online calculator will enable even users with no significant technical background to explore and exploit the innovative H-HOPE hydropower technology.
