📝 RED II Directive introduced Renewable Energy Communities in European legislation, while leaving to each member state the freedom to transpose them within a country-specific regulatory framework. 📌 In particular, countries like Portugal implemented a physical configuration, where shared renewable energy is directly included in the bill of REC’s members. Other countries, like Italy, preferred a virtual approach, allowing each member to freely choose its energy supplier. 💡 Among others, our analysis provides one important evidence. In physical configurations, the economic value of energy sharing is inevitably limited by the difference between the energy (market) price and the overall bill cost (including charges, levies and fees). Oppositely, in virtual ones, the state can determine the value of energy shared by means of a public incentive. This influences all the current and future exploitation of REC’s concept as an energy policy instrument. 🔜 To check all the other policy implications arising from diverse transpositions of RED II in different member states, you can access to the paper here: https://lnkd.in/dd5qGARD Giulia Taromboli Tiago Soares Jose Villar Collado Matteo Zatti Politecnico di Milano Universidade do Porto INESC TEC LEAP s.c.a r.l.

Chapter Two: Research Methodology In this chapter, I will discuss the methods I used to gather information about green hydrogen production, including production line costs, key equipment, office requirements, worker salaries, and the challenges I faced. Researching Green Hydrogen Production I began by analyzing core processes, focusing on water electrolysis powered by renewable energy such as solar and wind. The key components included electrolyzers, renewable energy systems, storage units, and transportation infrastructure. Cost Analysis and Operational Requirements I divided costs into fixed expenses, such as purchasing equipment and building the facility, and variable costs, such as maintenance and electricity. I also researched office requirements, staffing needs, and salaries based on industry standards and local data. Challenges and Overcoming Them I faced challenges in finding accurate data due to the novelty of green hydrogen and the limited number of global plants. Estimating local costs was also difficult due to variations in regulations and prices. To address this, I categorized information, consulted industry experts, and relied on regional case studies. This systematic approach helped me complete my research successfully.

Definition of solar energy Solar energy is radiant light and heat from the Sun that is harnessed using various technologies to generate electricity or provide heat for residential, commercial, and industrial purposes. It is a renewable and sustainable source of energy, as the Sun continuously emits vast amounts of energy that can be captured and converted into usable forms without depleting finite resources or causing significant environmental harm. Solar energy technologies include photovoltaic (PV) systems, which directly convert sunlight into electricity using solar panels, and solar thermal systems, which use sunlight to heat water or other fluids for applications such as space heating, water heating, and electricity generation through steam turbines. Solar energy is a key component of the transition to cleaner and more sustainable energy systems, as it produces no greenhouse gas emissions or air pollutants during operation, thereby helping to mitigate climate change and reduce dependence on fossil fuels.

How does a Wind Turbine Work ? A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin. The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to the rotation of a generator creates electricity. Source: Office of Energy Efficiency & Renewable Energy

A recent case study i.e. Production of hydrogen from renewable energy sources-case study from Universitat Politècnica de València (UPV) and Politechnika Krakowska underscores the vast potential of producing hydrogen from renewable energy sources like solar and wind in Spain. 🌍 🌟 The renewable energy landscape, characterized by abundant solar radiation and strong wind conditions, creates an ideal environment for hydrogen production. The case study highlights that surplus energy generated from these renewable sources can be effectively utilized for hydrogen production through water electrolysis, a method that offers a clean and sustainable alternative to conventional hydrogen production.   🔍 Key takeaways: ➡ Renewable Energy Utilization: Spain's excess renewable energy, especially during peak production months, can be redirected to hydrogen production, turning potential wastage into a valuable resource. ➡Sustainability: Hydrogen produced via water electrolysis using renewable energy sources presents a pathway to achieving carbon neutrality, aligning with Spain’s ambitious climate goals. ➡Industrial Applications: The hydrogen produced can significantly contribute to industries like ammonia production, methanol synthesis, and transportation, further pushing the envelope on industrial decarbonization. 📝 This case study serves as a blueprint for other regions looking to optimize their renewable energy resources and highlights the importance of investing in sustainable hydrogen production. At R.K.S. Technology & Services, we are committed to leveraging our expertise in advanced simulation and modeling to support the development of hydrogen technologies that will power a greener future. Let’s work together to accelerate the hydrogen economy and achieve a truly sustainable energy system.🌱 Source(s) :  Open Accesses | Report in Public domain 🛎 Stay tuned for more updates on various projects and industrial developments! | 🚀 Make sure your notification sound is turned on to get more (sharing daily)! 🤝 Q - How would you fell this approach of hydrogen production from renewable energy for sustainable way useful methods, and what recommendations would you make to others?

With the incoming Trump administration, concerns are rising over potential rollbacks of renewable energy incentives. How critical are these incentives for the future of clean energy? Currently 76% of queued solar capacity and 37% of queued wind capacity across the U.S. rely on tax credits to remain economically viable. By leveraging comprehensive interconnection queue data, power price forecasts, and detailed economic modeling, Enverus has identified the potential impact policy shifts could have on the renewable sector. As the energy landscape faces uncertainty, understanding the dynamics of policy and economics is essential for all stakeholders—developers, investors, and policymakers alike.

The results suggest that, given the existing capacity and potential for renewables, Türkiye can achieve a coal phase-out by early 2030s, alongside a trajectory towards a full-fledged fossil fuel phase-out in power generation. The results also indicate that while installed capacity and generation of coal-fired power plants are reduced, real GDP and electricity demand can be maintained and the carbon dioxide emissions from the power sector could be reduced by as much as 50% in 2030 compared to 2018 levels.

Here's a few more developments from around the world this week in the offshore industry! 🔌 Bibby Marine is building the world's first zero-emission electric Commissioning Service Operation Vessel (eCSOV) with Gondan Shipbuilders in Spain. eCSOV will use batteries and methanol engines for clean operation, with high-voltage offshore charging for quick power restoration. Designed by UK-based Longitude, this vessel can run on batteries for over 16 hours and is expected to be an industry game-changer. This project aligns with the UK government’s initiative to reduce maritime emissions. 💡 Greece and Saudi Arabia are moving forward with a potential electricity connection. A joint venture, Saudi Greek Interconnection, was established earlier in 2024 to explore the feasibility of an interconnector between the two countries. Technical and economic studies are now underway to assess the viability of the project. This builds on a 2022 agreement for broader energy cooperation that includes renewable energy, hydrogen transfer, and emissions reduction strategies. 📡 Norwegian company Argeo has been granted a patent for their innovative sensor system, Argeo Listen.
