Where are the G-res projects around the world? 🌍 🌊 🔍 The G-res Tool is a web-based tool for hydropower companies and researchers to estimate and report net greenhouse gas emissions from reservoirs.

The #hydropower report of the #CETO project (Nigel Taylor, Christian Thiel) is out! (EU Science, Research and Innovation). ✅ See the kick-off post below https://lnkd.in/deyNxipQ ✅ and the full report here https://lnkd.in/dr5q-un8   In this post, the key messages of chapter 2 are discussed, and we will continue next week with the second part of chapter 2.   ▶️ In the EU there are 4491 large dams according to the International Commission on Large Dams (ICOLD) 2023 register of dams and 33% are for multiple uses. According to ICOLD 2023, in the EU, 46% of single purpose reservoirs are for hydropower, 23% of multiple purpose reservoirs have hydropower as a first use, 6% as second use and 4% as third or fourth use. Overall, 48% of EU reservoirs are powered.   ▶️ Using the AMBER database, 450,000 barriers can be counted in EU’s rivers and less than 10% are dams. According to data from UNIDO, Voith Hydro and the JRC hydropower database, I estimated that less than 25,000 hydropower plants exist in the EU.   ▶️ In the years 1996–2019, a total of 342 barriers were dismantled in Europe, approximately 95% of which are so-called low barriers below 7.5 m height (and, not necessarily for hydropower, see above), restoring free flowing rivers and with benefits on the environment (dam removal EU)   ▶️ According to Eurostat, in 2022, the hydropower installed capacity was approximately 154 GW (46 GW of #pumped-storage hydro - PSH-, ¼ of the global installed capacity is in the EU).   ▶️ In the last decade, the annual energy generation from hydropower in the EU has oscillated between 322 and 398 TWh/y depending on the hydrological conditions with the average value being 363 TWh/y (including around 45 TWh/y from PSH)   ▶️ The installed hydropower per inhabitant is 0.34 kW/person in the EU, 0.31 kW/person in the U.S. and 0.30 kW/person in China, demonstrating that the EU is a strategic user of hydropower.   ▶️ According to International Hydropower Association (IHA) (2024), in 2023 the most relevant hydropower development in the EU were realized in Austria, Germany and Finland.   ▶️ The technical energy storage capacity of PSH reservoirs can be estimated with the data available in the IHA database at 1300 GWh (259 GWh closed loop and 957 from open loop), and the actual usable one is around 500 GWh.

"The dam is one of the main backbones of food self-sufficiency" says Indonesian Minster for Public Works. A massive program is under way in Indonesia, with 61 dams to be completed before 2026, together with the rehabilitation of the irrigation network. https://lnkd.in/evmku8hA

After the giant figuring on the French dam in Tignes, here is Mozilla figuring on the Iwayagawauchi dam in Japan. But while it took six tons of painting to draw on the Tignes dam, the Japanese was not created with paint, but was actually created by pressure washing. Après le géant herculéen de #Tignes, voilà que Mozilla s'installe sur la face du barrage japonais. Mais si Tignes a nécessité six tonnes de peinture, le barrage japonais de #Iwayagawauchi n'en a utilisé aucune peinture mais le dessin a été réalisé par un nettoyage à haute pression. https://lnkd.in/ekjZxe9c

Australia needs safe water infrastructure solutions in the face of climate challenges, including raising dams for #pumpedstorage, #damsafety upgrades, #floodmitigation and #WaterResources management projects where we need to meet the increasing demands placed on our existing resources and #water infrastructure.   Spain is a country with a long tradition in dam engineering and there are some lessons learned that could be used within the context of Australia.   I've pulled together some history, insights and examples around the Spanish practice for dams, including dam wall raising. You can also have a read of GHD's That's Dam Challenging guide, published following an industry event that took place earlier this year in Brisbane.   Enjoy reading and I hope we can catch up soon!   A big hand and massive thanks to my co-presenters and dear colleagues at the “That’s Dam Challenging” Peter Amos, Tracey Williamson, Emily Schwartz, PE, Martin Peter Bieri, David Cameron-Ellis, Andrew Reynolds, Colleen Baker, #PeterBuchanan, and Andrew Barclay.   Thanks also to our amazing team who made that event happen: Erica Pezzutti, Meg Sheehan, Emilley Kingsman, Stevie Joan Pitcher, Ben Hanslow, Nicholas Glover, Richard Evans, and Lindsey Brown   Also thanks to SPANCOLD - Comité Nacional Español de Grandes Presas SEPREM - Sociedad Española de Presas y Embalses ANCOLD The Australian National Committee on Large Dams Inc.   #Thatsdamchallenging #Sustainability #DamRaising #PumpedHydro #PumpedStorage #ClimateChange #Water #Dams #DamEngineering #Resilience #heritage #PowerofCommitment #FutureofWater #FutureEnergy #DamSafety

When the CEO of Indian's largest utility wants to show that he is using the best techniques, he explains that he is using ICOLD Bulletins for dam design or dam operation. Thank you Mr Chairman R. K Chaudhury for this recognition of the high value of ICOLD work ! 8 new Bulletins have been approved last month during the Annual Meeting of New Delhi #ICOLD2024, and they are already available in preprint format on ICOLD Website. Lorsque le PDG de la plus grande compagnie d'électricité indienne veut montrer qu'il utilise les meilleures techniques, il explique qu'il utilise les bulletins de la CIGB pour la conception ou l'exploitation des barrages. Merci à M. le Président R. K Chaudhury pour cette reconnaissance de la grande valeur du travail de la CIGB ! 8 nouveaux Bulletins ont été approuvés le mois dernier lors de la réunion annuelle de New Delhi de #ICOLD2024, et ils sont déjà disponibles en format « preprint » sur le site web de la CIGB.  #NHPC # https://lnkd.in/eEXvew-V

in United States of America, citizens from Maine are fighting to save their dams #SaveOurDams aux États-Unis, les citoyens du Maine se battent pour sauver leur barrage https://lnkd.in/ePAqbfYW

It seems ICOLD's involvement in EU research programs like ETIP HYDROPOWER and @Hydropower Europe is bringing interesting fruits. Thank you Honorary President Anton J. Schleiss for making this a reality !

Nigeria launches the first World Bank SPIN project (SPIN for sustainable power and irrigation for Nigeria), a very promising operation working from the beginning on the #Water_Food_Energy_nexus angle. ICOLD supports this initiative, which is going in the same direction that the recommendations of ICOLD Technical Bulletins 186, 173 and 171. https://lnkd.in/eFPQVMmr

Water storage is a crucial parameter for the climate change adaptation or mitigation. The report by the Multilateral Development banks is welcomed by ICOLD VP Liza Bensasson for reminding this fact.
