Easy Hydro was one of the 12 startups selected for the Phase 1 of the 2021 EIT RawMaterials Accelerator programme, with a focus on further refining our business model and exploring the opportunities given by the market.

Our team will work under the guidance and coaching of the EIT RawMaterials Consortium over the next three months, with the target of stepping up to Phase 2 later in the year.

New research published: Multi-Country Scale Assessment of Available Micro-Hydropower in operating Water Networks

Easy Hydro collaborates in a research to estimate the micro-hydropower potential in water networks across part of the EU

The Easy Hydro team has participated in a research focused on the quantification of the available energy recovery in water networks including drinking water, wastewater and irrigation across several EU countries as part of the REDAWN project. A total energy recovery potential ranging between 480 – 822 GWh was estimated, which would decrease the energy consumption of the water networks between 1.7 and 13%. This would significantly reduce the CO2 emissions associated with the water industry, whilst actively contributing to net energy efficiency gains.

Very interesting results, which will foster the adoption of micro hydropower solutions to counteract the effects of climate change and advance the EU targets regarding decarbonizing the economy.

The advantages of using Pumps-as-turbines hydro converters

Cost reduction and maintenance simplification give an edge over conventional water turbines

The key advantages of choosing a pump-as-turbine for small scale hydro power generation are:

  • Riduzione dei costi di installazione grazie all'uso di macchinari standard e non costruiti su misura
  • Facilità di manutenzione, con parti di ricambio disponibili a magazzino
  • Quick equipment lead time, typically 2-3 monts
  • Available in cast iron or bronze for special applications
  • Certified for use with drinking water

Energy recovery from the water supply of Tara Mines

Press Release

The Project

Easy Hydro, a spinout from Trinity College di Dublino, has been awarded a €49,000 Booster grant from the EU consortium EIT RawMaterials to build a pilot energy recovery installation at Tara Mines in Navan. As a part of a collaboration between Easy Hydro and the site owner Boliden, a novel type of water turbine will be commissioned to recover energy from the underground water mains carrying fresh water down the mine.

The site

It has been decided to place the Easy Hydro turbine in parallel to an existing pressure reducing station on a DN150 pipeline carrying clean water from the surface.

With an average flow rate of 22 l/s and a pressure drop of 21 bar, the turbine will output up to 30 kW of clean renewable energy resulting in yearly savings of over 200 MWh of electricity otherwise imported from the grid. Such amount of energy corresponds to the annual consumption of nearly 50 average Irish households.

The proposed installation will directly offset over 60 tons of CO2 per year, and such technology if replicated over a number of other similar locations within the same mine has the potential to significantly reduce the current carbon footprint of Tara Mines.

Besides, the expected payback time of the installation is between 2 and 3 years and considering an equipment life of 25 years the generated energy will feature an extremely low Levelized Cost Of Electricity (LCOE).

This work is highly relevant to our wider sustainability agenda and compatible with the underground mining operations carried out by Boliden Tara Mines

Description of the technology

Small-scale and modular hydropower turbines which can be installed along existing pipe networks. Such turbines can be placed in a bypass of an existing valve, e.g. pressure reducing valves, control valves, tank inflow regulation valves. The turbine can thus transform the dissipated pressure into usable electricity, with power outputs ranging from a few kilowatts up to hundreds of kilowatts.

The type of turbine adopted is reliable and widely tested and consists of standard pumps running in reverse as turbines (PAT – Pumps As Turbines) which only cost a fraction of a conventional custom-made hydro turbine.

  • Caratteristiche:
    • Le turbine Easy Hydro consistono in pompe centrifughe standard utilizzate come generatori idroelettrici
    • Range di potenza nominale da 1 to 300+ kW, range di portate da 15 to 3,600+ m3/h, range di pressioni da 1 a 300 bar
  • Vantaggi:
    • Ridotto costo di installazione, just a fraction of a conventional turbine (Francis, Pelton, Crossflow…)
    • Facilità di manutenzione, as pump spare parts and skilled technicians are easily available
    • Sistema modulare, plug and play
    • Fail-safe bypass and hands-off operations
  • Values:
    • Possibilità di sfruttare un potenziale esistente within an existing pipe infrastructure
    • Ridurre il fabbisogno di elettricità e le emissioni di anidride carbonica of a mine

Energy recovery from on-demand irrigation networks: an opportunity to reduce the energy demand and bring electricity to remote places

The modernization of hydraulic infrastructure in irrigation, from traditional channels and ditches to pressurized networks, has led to significant improvement of the water efficiency (conveyance and consumption). Nevertheless, this fact brought a dramatic increase of the energy consumption, causing impacts on farming margins and operational costs.


On-demand irrigation networks have the main advantage of offering continuous water availability, giving a great flexibility to farmers for irrigating. However, the occurrence of areas with excess pressure, which must be dissipated in some way, has become more frequent. Micro-hydropower turbines for energy recovery arise as an attractive solution to counteract the negative impacts due to the high energy cost of the process. Given the seasonality of the activity, cost-effective solutions are in dire need and hydropower stands out as a technology capable of bringing electricity to remote places with no grid connection where an excessive water pressure to be dissipated within an irrigation pipe.

Easy Hydro secures an exclusive IP licence agreement

The rights to use the pump-as-turbine selection software has been granted to the Venture by Trinity College di Dublino.

The selection software enables an accurate selection of the most suitable hydraulic pump (end-suction, inline, multistage, split-case) to work as a turbine for any given site. Until now, the available alternatives were either experimentally testing many different pumps in reverse or performing a numerical CFD simulation to predict their performances – both extremely time and resource consuming methods.

In-pipe pico hydropower saves an Irish rural water network 15,600 kWh of electricity

The 3 kW peak pico pump-as-turbine designed by the Easy Hydro team has been operating for the last 12 months. The turbine is located at the inlet of a gravity-fed raw water supply line, and contributes to reducing the energy demand of the adjacent treatment works by nearly 20%.
