Possible increased revenue, as well as a significant increase in energy production, following the repair of moderate blade erosion.
The Offshore Renewable Energy (ORE) Catapult, in collaboration with Centrica, has successfully delivered the first in-field measurement campaign under its industry-leading blade leading edge programme (BLEEP), and concluded that an uplift in annual energy production (AEP) of between 1.5 to 2% is possible following the repair of moderate blade erosion.
The measurement campaign, carried out on behalf of ORE Catapult by the Measurement Services Department at RES, in collaboration with Centrica and focused on an offshore wind farm, used LiDAR technology to accurately measure the power performance impact of blade leading edge erosion by assessing performance before and after blade repairs were carried out.
The results will allow owner/operators to optimise their repair and maintenance strategies, balancing cost versus benefit in order to minimise levelised cost of energy impact and maximise revenue.
The resultant method will now be used to carry out a further two measurement campaigns as part of the wider collaborative industry programme of works, to validate the results and the methodology used.
Andrew Kay, ORE Catapult’s Innovation Manager, said: “Blade leading edge erosion remains a significant issue for the wind power industry. The outcomes from this project will help the industry to optimise blade maintenance informed by an understanding of both the cost and the benefit of repair work.
“However, this measurement represents a single result from a single turbine type, site, and level of erosion. As such it is extremely important that further studies are performed to build a more complete picture of how the level of erosion, site, turbine and atmospheric variables influence the impact of erosion on performance.
The methodology developed and executed as part of this campaign could also be used in the assessment of proactive turbine upgrades such as aerodynamic or control improvements as well as to assess the impact of leading edge protection products on power performance.
Bailey Bradley, Renewables Commercial Manager for Centrica, added: “Understanding and quantifying the impact of leading edge erosion on turbine performance is essential in order to manage the operating business, planning and forecasting and managing the OEM to help them to plan blade inspection and repair activities. ORE Catapult has brought operators together to participate in BLEEP, enabling the sector to share knowledge and reduce costs. It is often difficult for operators to share knowledge and data but ORE Catapult’s independence has enabled it to facilitate this and win the trust of the participants.”
Simon Feeney, Commercial Manager of the Measurement Services Department at RES said: “RES were delighted to support ORE Catapult in this groundbreaking innovative project. The ZephIR LiDAR technology selected for the measurement campaign, ZephIR DM, allowed small changes in the turbine performance to be detected and the full rotor measurement allowed us to isolate changes as a result of the blade repair from seasonal and diurnal shifts in performance. This first-of-a-kind campaign shows there is a real benefit to Annual Energy Production by taking a proactive approach to turbine maintenance”
7 New Technologies That Could Radically Change Our Energy Consumption
Most of our focus on technological development to lessen our environmental impact has been focused on cleaner, more efficient methods of generating electricity. The cost of solar energy production, for example, is slated to fall more than 75 percent between 2010 and 2020.
This is a massive step forward, and it’s good that engineers and researchers are working for even more advancements in this area. But what about technologies that reduce the amount of energy we demand in the first place?
Though it doesn’t get as much attention in the press, we’re making tremendous progress in this area, too.
New Technologies to Watch
These are some of the top emerging technologies that have the power to reduce our energy demands:
- Self-driving cars. Self-driving cars are still in development, but they’re already being hailed as potential ways to eliminate a number of problems on the road, including the epidemic of distracted driving ironically driven by other new technologies. However, even autonomous vehicle proponents often miss the tremendous energy savings that self-driving cars could have on the world. With a fleet of autonomous vehicles at our beck and call, consumers will spend less time driving themselves and more time carpooling, dramatically reducing overall fuel consumption once it’s fully adopted.
- Magnetocaloric tech. The magnetocaloric effect isn’t exactly new—it was actually discovered in 1881—but it’s only recently being studied and applied to commercial appliances. Essentially, this technology relies on changing magnetic fields to produce a cooling effect, which could be used in refrigerators and air conditioners to significantly reduce the amount of electricity required.
- New types of insulation. Insulation is the best asset we have to keep our homes thermoregulated; they keep cold or warm air in (depending on the season) and keep warm or cold air out (again, depending on the season). New insulation technology has the power to improve this efficiency many times over, decreasing our need for heating and cooling entirely. For example, some new automated sealing technologies can seal gaps between 0.5 inches wide and the width of a human hair.
- Better lights. Fluorescent bulbs were a dramatic improvement over incandescent bulbs, and LEDs were a dramatic improvement over fluorescent bulbs—but the improvements may not end there. Scientists are currently researching even better types of light bulbs, and more efficient applications of LEDs while they’re at it.
- Better heat pumps. Heat pumps are built to transfer heat from one location to another, and can be used to efficiently manage temperatures—keeping homes warm while requiring less energy expenditure. For example, some heat pumps are built for residential heating and cooling, while others are being used to make more efficient appliances, like dryers.
- The internet of things. The internet of things and “smart” devices is another development that can significantly reduce our energy demands. For example, “smart” windows may be able to respond dynamically to changing light conditions to heat or cool the house more efficiently, and “smart” refrigerators may be able to respond dynamically to new conditions. There are several reasons for this improvement. First, smart devices automate things, so it’s easier to control your energy consumption. Second, they track your consumption patterns, so it’s easier to conceptualize your impact. Third, they’re often designed with efficiency in mind from the beginning, reducing energy demands, even without the high-tech interfaces.
- Machine learning. Machine learning and artificial intelligence (AI) technologies have the power to improve almost every other item on this list. By studying consumer patterns and recommending new strategies, or automatically controlling certain features, machine learning algorithms have the power to fundamentally change how we use energy in our homes and businesses.
Making the Investment
All technologies need time, money, and consumer acceptance to be developed. Fortunately, a growing number of consumers are becoming enthusiastic about finding new ways to reduce their energy consumption and overall environmental impact. As long as we keep making the investment, our tools to create cleaner energy and demand less energy in the first place should have a massive positive effect on our environment—and even our daily lives.
