Pengimbangan Emisi Dua Tahun – Bagaimana Turbin Angin Melakukannya?

An eye-opening study published in the Journal of the Royal Society of New Zealand examines how onshore wind farms can limit their negative environmental impact and improve efficiency. Interestingly, the report highlights that today’s system can offset their emissions in as little as two years. Here’s what you need to know.

Penelitian tentang Keberlanjutan Ladang Angin

The peer-reviewed study examined the life cycle of these devices. The team considered all aspects of wind turbines including manufacturing, delivery, installation, maintenance, and decommissioning of these units. The goal was to determine the inefficiencies and see how they could be reduced if not eliminated in the future.

Studi ini dilakukan di Hawke’s Bay, Selandia Baru pada ladang angin darat Harapaki. Lokasi ini ideal karena pengaturannya mirip dengan sebagian besar operasi darat secara global. Dengan demikian, hal ini memungkinkan peneliti memperoleh data yang paling relevan dari upaya mereka.

Sumber – Teknologi Daya

Harapaki wind farm has 41 onshore wind turbines in operation. These units were found to generate all the energy needed for their entire life cycle in around 6 months. Additionally, the research demonstrated that the average wind farm has a carbon footprint of 10.8 gCO2eq/kWh. The results indicate that wind farms can offset their lifespans’ carbon footprint in 2 years. Interestingly, combined gas turbine units were found to accomplish the task in 1.7 years.

Manufaktur

Menyelami data mengungkapkan bahwa manufaktur adalah salah satu kontributor utama jejak karbon ladang angin darat. Ini adalah proses yang intensif tenaga kerja dan material untuk menciptakan komponen ladang angin darat berefisiensi tinggi saat ini. Perangkat ini memerlukan mesin yang dibangun khusus dan dapat menggunakan komposit mutakhir untuk mengurangi berat. Faktor-faktor ini menambah biaya serta dampak lingkungan yang ditimbulkan perangkat tersebut.

Instalasi

Mungkin mengejutkan untuk mengetahui bahwa transportasi ladang angin ke lokasi mereka adalah salah satu biaya terbesar. Secara khusus, laporan menemukan bahwa memindahkan komponen besar ini ke lokasi akhir dapat menyumbang lebih dari 10% dari total emisi karbon perangkat. Proses membawa ladang angin besar ke lokasi melibatkan truk dan crane besar yang tidak dirancang untuk keberlanjutan.

Dekomisioning Ladang Angin

Dekomisioning turbin angin besar adalah tugas lain yang mahal dan membebani lingkungan yang juga diteliti. Peneliti menemukan bahwa dekomisioning ladang angin sering meningkatkan jejak karbon. Secara khusus, di Harapaki, 41 unit didekomisioning namun bilah yang dapat digunakan diperbaiki kembali.

Memperbaiki kembali bilah menggunakan metode mekanik dan kimia secara signifikan mengurangi emisi manufaktur. Peneliti memprediksi bahwa penyesuaian sederhana ini berpotensi menurunkan emisi dari 10,8 gCO2eq menjadi sekitar 9,7.

Peneliti

The researchers behind this report include lead author Isabella Pimentel Pincelli from the Sustainable Energy Systems research group, Wellington Faculty of Engineering, at Te Herenga Waka Victoria University of Wellington. Additionally, Professor Alan Brent, Chair in Sustainable Energy Systems at Wellington Co-authored the research paper.

Angin Menjadi Pilihan Energi Terbarukan Paling Cerdas

Wind farms are now seen by many as the ideal renewable energy solution. These devices can provide 24/7 power when located in a windy environment. Additionally, they can be stationed on or offshore, and even in urban environments atop buildings.

Ladang Angin Menyediakan Efisiensi Lebih Tinggi

The rise of wind farms is not an accident. There have been numerous studies conducted over the last few years highlighting wind framing advantages. For example, wind farms outproduce solar farms in efficiency by as high as 20%. Studies found that the best solar panels produce 23% usable electricity while wind farm turbines can hit 40% energy production.

Solusi Baterai yang Meningkatkan Ladang Angin

Batteries are another crucial component of the renewable sector that is often overlooked. The introduction of faster charging, more reliable, and affordable batteries has helped to drive renewables adoption up. It also helps to reduce overall operating costs.

More efficient batteries could reduce the workload for wind turbines. They could also enable more smart networks. These systems have the capability to take stored energy and trade it, sell it, or apply it as needed to improve stability.

Tenaga Angin Tidak Sempurna

There is no perfect solution to the world’s energy demands. Wind power, alongside other sustainable energy options, can provide some assistance but is not at the point where it can completely replace fossil fuels power generation.

Secara khusus, satu hambatan utama adopsi ladang angin skala besar adalah biaya pemeliharaan. Orang kebanyakan tidak menyadari kerusakan yang dialami ujung baling-baling turbin angin. Angin dapat mengikis tepi baling-baling tersebut, membuatnya jauh kurang efisien. Sayangnya, mengganti unit-unit ini tidak murah dan bila memperhitungkan waktu pengiriman serta instalasi, sebuah turbin angin dapat tidak beroperasi selama berbulan‑bulan untuk memperbaiki satu baling-baling.

Wind power is a good solution for communities but it hasn’t found the right niche within the single home markets. These units are not cost-effective enough for a homeowner to invest in one for their property. As such, there has been little research or products for small-scale wind farming.

Hewan Menderita

Turbin angin juga dapat mengganggu ekosistem lokal dan satwa liar. Unit penangkap angin besar ini dapat menghasilkan hembusan kuat yang dapat menyebabkan burung keluar jalur bahkan menabrak baling‑baling. Studi mengungkapkan ratusan kematian burung setiap tahun di setiap ladang angin besar.

Selain itu, kebisingan yang dihasilkan oleh perangkat mekanik besar ini dapat menyebabkan ketidaknyamanan pada lingkungan. Selain keluhan manusia, kelelawar dapat kehilangan kemampuan ekolokasi mereka, membuat hewan ini tersesat dan tidak dapat menemukan tempat tinggalnya. Oleh karena itu, ada gerakan kuat untuk mencoba mengatasi kekhawatiran ini.

Terobosan Lain dalam Teknologi Pertanian Angin

Wind farming has seen some considerable advancement that has helped it become the premier renewable energy production option. AI computer modeling and other tech breakthroughs continue to drive efficiency and production.

Bilah Melengkung

The innovative team from Knight and Carver’s Wind Blade Division in National City, California, collaborated with researchers at the Department of Energy’s Sandia National Laboratories to improve propeller design and enhance performance. The Sweep Twist Adaptive Rotor (STAR) blade has been shown to improve efficiency by 12%. The secret to its enhanced performance is a slightly curved tip. The researchers used computer modeling to create the curve perfectly to maximize energy generation.

Simulator

Computer simulations are playing an increasingly important role in the development and deployment of wind farms. These systems allow engineers to pressure test new concepts without the need to create the units directly. This strategy lowers costs and allows engineers to take their creations to their performance limits.

Jaringan Listrik Pintar

Smart power grids are one technology that has renewable engineers excited. These systems can monitor and transfer energy and data in real-time to drive efficiency. Today’s most advanced power grid solutions leverage AI options to provide the best results possible. In the future, these solutions will make it even easier to share your unused energy and secure rewards.
