New #TrinityResearch led by Prof Jin Zhao from Trinity's School of Engineering shows that power grids supplied largely by renewable sources experience lower intensity blackouts, at least in the US, where the data came from. The research – just published in leading international journal Nature Energy – was conducted with US blackout data from 2001 to 2020, but the results are of great interest from an Irish perspective as we rapidly transition to power grids primarily supplied by weather-dependent renewable energy sources. In 2023, 38.9% of electricity generated in Ireland came from renewable energy sources and this figure is expected to grow to above 70% by 2030. Prof. Zhao said: “This is promising from an Irish perspective, although we are a lower-inertia island system that could be more sensitive than the large interconnected systems like those seen in the US and in the power systems of continental Europe. All of this makes it super important to specifically focus on our Irish power system with similar research and that is the next step for us – we have recently secured funding to do just that.” Read more at: https://lnkd.in/e8UtJ6VB

Join us for a webinar on "Tripling Renewable Capacity Until 2030 – Current Status and the Way Forward" by Prof. Dr. Anke Weidlich. Prof. Dr. Weidlich is a Professor of Control and Integration of Grids at INATECH. And, Member of the board of directors of Smart Grids-Plattform Baden-Württemberg e.V. and of the Energy Informatics at the German Informatics Society. Brief Overview: In order to reach the goal set by the Paris agreements, renewable energy must be expanded at unprecedented speed. Tripling its capacity until 2030 is a huge challenge, but it is not unrealistic that it can be achieved. The talk will look at the current status of renewable energy expansion and its recent developments. It also puts the spot on what other technologies are necessary beyond solar energy, and what challenges need to be solved for integrating all the fluctuating renewables into the grid. It takes both a global perspective as well as a closer look at the example of Germany. 📅 Tue 26th March, 3pm CET 📍 Online. Register here: https://lnkd.in/eKvRR57k 🔔 Open to all

As the world increasingly taps into renewable energy, scientists are exploring the best ways to manage excess energy efficiently throughout the day—including during peak usage, on cloudy days, or when there is little to no wind. In a recent study, a group of Turkish researchers found that hydrogen storage can store renewable energy at large scales and relatively low costs. For example, their model suggests that if Germany expanded its use of hydrogen storage at renewable energy plants nationwide, this would result in roughly 60% lower costs than the nation’s current energy systems.   Read the full article by Sovana Qudaih, Zeynep Bektaş, PhD, Denizhan Güven, Gulgun Kayakutlu, and Mehmet Özgür Kayalica in IEEE Transactions on Engineering Management. https://lnkd.in/e7DUMBiG   #hydrogenstorage #renewableenergy IEEE IEEE TEMS: Technology and Engineering Management Society IEEE Spectrum

🌞💨 Exciting News! Our latest research article published yesterday in the journal Renewable Energy Focus studies the complementarity between solar and wind energy production to tackle some issues connected with the intermittency of renewable energy sources. - Complementarity is a simple concept suggesting that combining solar and wind generation aligns better with actual energy use, compared with generation from these sources individually. - Using open-source data, we propose quantitative methods to study complementarity that are easy to use, interpret, and communicate to the wider public.  - We also equipped real hourly generation data to study “dunkelflaute” events (periods of low renewable generation) in Central Europe, calculating their occurrence and length in 43,800 unique hours. - As far as we know, this is the first quantitative study of wind-solar complementarity in Slovakia. We practically demonstrate that complementarity can be studied even in countries with limited renewable resources. 📉🌪️ This research not only advances the understanding of renewable energy integration but also provides policymakers and stakeholders with data and arguments to advocate for balanced renewable energy policies. 🌱📊 I am super proud that this paper was written in close cooperation with my two interns from last summer, Robert Sabovcik and Martin Šinka. Only due to their drive and passion, an idea which started as a very simplistic graph (see comments) drawn on a whiteboard made it to the pages of a widely respected academic journal! https://lnkd.in/dzTJ9vtX

The goal is to develop a reliable 4 MW electricity production system that overcomes the intermittency challenges of renewable energy. This innovative technology will help create a more robust and resilient energy infrastructure by storing excess thermal energy and converting it to power through a steam generator. The system's three key stages—power unit, molten salt storage, and power generation—work together to harness the benefits of thermal energy storage. As we push the boundaries of scientific research, KEO International remains committed to powering the future and addressing the energy challenges of tomorrow. We will keep you closely posted about our latest findings and progress in this transformative initiative.

NEW | "The feasibility and policy engagements in achieving net zero emission in China's power sector by 2050: A LEAP-REP model analysis" co-authored by Chinese Visiting Scholar Sufang Zhang In this study, Sufang et al. propose a renewable energy penetration model to examine the feasibility of achieving net-zero emissions by 2050 in China's power sector. They find that it is possible for the power sector to achieve net-zero emissions by 2050 while meeting the growing electricity demand, with a renewable energy penetration rate of 75%.
