New ‘Dynamic Yaw’ tech to supercharge wind turbine efficiency ◾ In an attempt to license and deploy an innovative technology to optimize the performance of wind turbines, the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) collaborated with Renewable Energy Systems (RES), the world’s largest independent renewables company. ◾ Currently, wind turbines operate independently, prioritising their own energy output without considering the overall wind farm performance. ◾ Additionally, while each turbine has detailed local wind data, this information isn’t shared to optimise production across the entire farm, leading to reduced efficiency and increased stress on the turbines. ◾ RES’ Dynamic Yaw system employs control and wake steering techniques to enhance wind turbine yaw decisions, resulting in improved overall performance and efficiency, enabling wind farms to reach their full potential, according to the company. ◾ The ‘Dynamic Yaw’ technology effectively innovates the yaw system of wind turbines – the component responsible for the orientation of a turbine toward the wind – to maximize the overall performance and efficiency of turbines in a wind farm. ◾ “The ‘Dynamic Yaw’ technology will help wind asset owners optimize the overall output of their assets through better utilization of their data, and subsequent autonomous action of the asset.” ◾ RES has tested the technology for over seven years across turbines at wind farms in the UK. Dynamic Yaw is a software product that interacts with existing turbine controller hardware. ◾ RES Yaw Control optimises turbine alignment and maximises energy capture by improving yaw decisions. The company claims that collective control minimises costs by reducing yaw activations, which decreases wear and tear on the system, by preventing responses to short-term turbulence. ◾ This systems approach has the effect of improving overall energy efficiency by adding the equivalent of 1-3 wind turbines to a 100 turbine-strong wind farm through enhanced management and controls, reported Business Wire. ◾ Bamberger claimed that by sharing farm wide data and transforming the yaw optimization strategy of a wind farm to maximize overall performance, the ‘Dynamic Yaw’ transforms a collection of individual turbines into a team. ◾ The technology can be installed anywhere in the world, bridging the gap between digital data and action on site. ◾ The technology will boost the energy efficiency of wind farms and improve supply chain efficiencies by enabling production of more renewable energy from the same investment. ◾ This will allow more efficient capital allocation – to extract all available renewable energy from our existing assets, reported Business Wire.

BMW trials ’motionless’ wind energy system on top of its Mini plant in Oxford ◾ On the roof of BMW Group’s Oxford plant is a prototype bladeless wind energy solution that is harnessing wind power to produce clean energy. ◾ This pilot unit has been developed by US start-up Aeromine Technologies, which was founded in 2021 with the aim of bringing the wind energy to the rooftop power generation market. The noiseless and vibration-free units have been designed to sit on the edge of flat roofs, where they are orientated towards the prevailing wind. ◾ The technology leverages aerodynamics similar to airfoils on a race car in that the unit’s wing-like vertical airfoils create a vacuum effect, drawing air behind an internal propeller to generate clean electricity. ◾ Aeromine claims that if its system – which consists of 20 to 40 units and is typically 50kW or larger – is installed alongside solar panels, the two technologies can generate all of a building’s on-site energy needs, while minimising the need for energy storage. ◾ Claus Lønborg, managing director of Aeromine, said: “Our ‘motionless’ wind energy technology is designed to work seamlessly alongside solar systems, maximising the renewable energy output from rooftops while helping address challenges like noise, vibrations and wildlife impact.” ◾ Having deployed its first pilot unit in 2022 on the roof of BASF’s manufacturing plant in Michigan, the start-up is installing additional pilot units, such as the one at BMW’s Oxford plant, so as to de-risk the technology before full commercial product launch in 2024. ◾ Aeromine’s technology will complement Mini Plant Oxford’s 10-year-old solar arrays, which consist of 11,000 panels. While the solar panels are effective at generating electricity, they are less so during winter and the evening hours. ◾ BMW will now begin assessing the unit’s potential to enhance energy efficiency across BMW sites around the world, as well as commercial buildings in the UK. ◾ This energy project is part of the BMW Startup Garage, a business unit that works with early-stage start-ups by testing their prototypes during a pilot project and then commissioning the start-up as a supplier at an early stage. ◾ Carmen Gargioni, team lead innovation at BMW Group Real Estate Management, said: “The BMW Startup Garage acts as a matchmaker between start-ups and different business units. New technologies are essential as we strive to find the most efficient solution to our requirements. This includes exciting innovations from new players.” The source: Engineering and Technology #energyticslimited #renewableenergy #windenergy #bladelesswindenergy #bmw #aeromine

How bypass diodes work in a solar panel? Most modern solar panels contain bypass diodes to provide an alternate current path when a cell or multiple cells become shaded or faulty. Most solar panels are divided into three groups of cells connected in series, with each group containing a bypass diode. In older 60-cell panels, the panel is divided into three groups of 20 cells, while in modern split-cell panels, the panel is divided into six groups of either 20 or 24 cells, with two groups associated with one bypass diode. If it were cost-effective, there would be one bypass diode for each cell, but this is complex and expensive to integrate, so most manufacturers use one diode for a group of series cells. The bypass diode activates when one or more cells in the group are shaded or underperforming, resulting in a voltage and current drop. Solar cells in a typical panel generate about 0.5 to 0.6 volts under standard conditions. For a group of 20 cells, the total output would be around 12 volts. Meanwhile, a typical bypass diode has an activation voltage of approximately 0.7 volts, known as the forward voltage threshold. If a section of cells is shaded, the voltage and current can drop significantly. When the forward voltage across the diode (i.e., the voltage from the unshaded cells in the rest of the string is higher than the voltage of the shaded section) exceeds about 0.7 volts, the diode becomes forward-biased and allows current to flow. This effectively bypasses the shaded cells, allowing the rest of the panel and string to operate at a higher efficiency. Light shading If the system suffers from regular shading over a large area due to a nearby tree, the panels will encounter what could be judged as medium or light shading. In this instance, the bypass diodes may not be forced to activate due to the large shaded area over numerous panels. Significant shading also results in lower string voltage and current, resulting in less heating if the diodes are activated. In this situation, the diodes may not need to function and could work without issues for a long time. Additionally, if the shading occurs early in the morning or later in the afternoon, the amount of sunlight (solar irradiance) will be much lower, reducing the voltage and current in the string. This, in turn, results in far less thermal stress on bypass diodes if they are active due to shade. Heavy shading On the other hand, it has been found that rigid or fixed shading over a small area on panels installed next to roof vents and chimneys can cause diodes to be active for long periods of time, leading to premature failure. This is especially true if the shading occurs in the middle of the day when the solar irradiance is at its peak. Failed bypass diodes can allow a reverse current to heat up the shaded cells, resulting in burn marks from extreme hot spots.

Are hydrogen cars more efficient than electric? ◾A recent study revealed important facts about the efficiency of hydrogen use in various sectors of transport, whether land, sea or air. ◾The new scientific paper from academics at the University of Michigan compared energy losses across the value chain when using batteries, hydrogen and synthetic fuels to operate vehicles on roads, trains, ships and aircraft. ◾The study is described as the first "to calculate the overall system efficiency using renewable electricity as a primary energy source for all energy inputs throughout operations (e.g. hydrogen transport, process heat for artificial fuel production, carbon capture directly from the air)." ◾According to the study, hydrogen produced through water electrolysis using renewable electricity can help decarbonize transport, either directly in the fuel cell or engine, or indirectly as an artificial fuel. ◾However, the system's inefficiency during the production, storage, transport, distribution and use of hydrogen or synthetic fuels results in a loss of approximately 80-90% of primary power inputs. ◾The study assessed the energy efficiency and intensity of hydrogen pathways in land, air and sea transport, and calculated in (2019) and future (2035) efficiency, using renewable electricity as the primary source of all energy inputs, while comparing the results to battery options. ◾The results showed that electric-powered transport is currently about 3-8 times more efficient than hydrogen alternatives. ◾Operating all transportation in the United States with green hydrogen will require 10 times more renewable electricity currently produced, and 3-4 times more than expected in 2035. ◾The study stated that the provision of one unit of power for wheels or propulsion required 4.5-6.7 units (direct hydrogen) and 7.3-11.9 units (synthetic fuel) of primary renewable electricity inputs, compared to 1.4-1.9 units for electrification tracks (battery). ◾The study found that electrification of all renewable electricity transport requires significant investments in generation capacity, which means that priority must be given to its expansion. ◾Electric vehicles (especially light), aircraft (less than 200 miles), vessels (short distance), and railways (where electricity infrastructure is available), are superior in energy to hydrogen-based options, as solutions to decarbonize transport. ◾Renewable sources of electricity are insufficient to support the production of hydrogen for light vehicles, which presents a challenge for hydrogen cars. ◾The study also found that carbon-based synthetic fuels are attractive because of their high energy intensity, easy handling and compatibility with existing vehicles and fuel infrastructure, but from an energy efficiency perspective, they are less attractive than direct hydrogen pathways.

How is geothermal energy used? ◾The three most common uses for geothermal energy are direct use, power generation, and ground source heating and cooling. ◾Geothermal direct-use systems Tap into naturally heated ground water that’s found a few feet to less than a mile below the earth’s surface. Wells are drilled to extract the ground water, which can be as hot as 200°F or more. In some cases, the hot water or steam might rise up on its own, without the need for active pumping, and can be used directly or cycled through a heat exchanger. Direct-use geothermal water supports many applications, including warming fishing farms, melting ice and snow on sidewalks and roads, heating large pools, heating buildings, and providing hot water. Although direct-use geothermal systems have lower capital costs than deeper geothermal systems, the technology is limited to areas that have natural bodies of hot groundwater near or at the earth’s surface, such as regions with volcanic or tectonic activity. ◾Power generation The three types of geothermal power plants tap into geothermal resources deep inside the earth to produce electricity. Most have closed-loop water systems, where they pump the extracted water directly back into the geothermal reservoir after use. Since much of the water has been vaporized into steam, the plants need to re-inject substantial amounts of water to maintain a steady volume of water in the reservoir. Although geothermal energy is a renewable resource that is used in about 20 countries today, most geothermal wells will cool over time, especially when heat is extracted faster than the water is replenished. ◾Geothermal heating and cooling Also known as ground source heating and cooling, this is the most common way geothermal energy is used today. To answer the question “what is geothermal heating,” it’s important to understand how a geothermal heat pump (also called a ground source heat pump) works. Instead of generating heat, the pump uses the earth as its heat source and moves the heat around between the earth and the home or building. The pump is drilled between 10 and 300 feet into the earth and connects to long loops of pipe that circulate liquid underground and throughout the building. In the winter, the liquid absorbs the earth’s heat and carries it into the building, where geothermal heating releases it through a duct system. In the summer, the liquid absorbs the heat in the building and carries it down to the earth for cooling. ◾More ways geothermal energy is used 🔸Agriculture uses geothermal energy to keep plants warm in winter by applying steam to the soil. 🔸Some health spas use geothermal vents to heat their hot tubs and baths. 🔸Hot springs are known for their therapeutic ability to improve people’s health. 🔸Natural geysers can be awe-inspiring tourist attractions The source: Interesting Engineering #energyticslimited #renewableenergy #geothermalenergy #geothermaldirectusesystem #geothermalheatingandcooling

Unique ‘flying saucer’-like wave energy converter eyes real-world deployment ◾CETO, a fully submerged wave energy converter (WEC) from Australian company Carnegie Clean Energy, is seeking a certification from the marine classification society Lloyd’s Register to demonstrate that its technology conforms to the International Electrotechnical Commission’s Renewable Energy (IECRE) System, a press release said. ◾While the world seeks to meet its surging energy demands from wind and solar power plants, a huge reserve of energy available across 70 percent of the Earth remains untapped. As per estimates from the US Department of Energy, the kinetic energy in tidal waves can single-handedly meet 60 percent of US energy demand. ◾However, the hurdle in achieving this feat has been developing a cost-effective and efficient design that can convert the energy in the waves into electrical energy that can be supplied through the grid. ◾Named after the Greek sea goddess CETO, the device features a buoyant actuator that generates carbon-free electricity from the movement of the waves. The prototype was developed at the Biscay Marine Energy Platform (BiMEP) in Basque Country, Spain, and is expected to be deployed in 2025. ◾Even as the results from its deployment are awaited, Carnegie Clean Energy is keen to demonstrate that its wave energy conversion technology is at par with solar and wind energy devices that have been commercially deployed worldwide. ◾It has approached Lloyd’s Register to assess the CETO device by the International Electrotechnical Commission’s Renewable Energy (IECRE) System’s operational document OD-310-4. ◾A team of six specialists will now evaluate the novel aspects of the CETO design through the IECRE technology qualification process, determine its feasibility, validate its technology, and provide a conformity statement for its technology qualification. ◾This would be an important step that CETO would go through on its way to achieving type certification.
