CNC Laser and Plasma: Innovative Technologies in Steel Processing
Steel is a durable and versatile material that has a wide range of uses in industry. CNC laser and plasma technologies offer highly effective and innovative solutions in the processing of this material. Both laser and plasma cutting techniques play an important role in precision machining and creating complex patterns on steel. CNC Laser and Steel Machining CNC laser cutting provides precise cutting of steel sheets through the use of a high-intensity laser beam. This technology makes it possible to engrave fine details and complex patterns on steel. Steel parts cut with CNC laser can be used in a wide range of applications, from industrial production to works of art. Plasma Cutting Technology and Steel Plasma cutting enables the cutting of steel sheets through the use of a high-temperature plasma jet. This method allows fast and effective cutting of thick steel sheets. Plasma cutting is generally preferred for cutting thicker and larger steel parts in industrial production processes. CNC Technology and Efficiency in Steel Processing CNC (Computer Numerical Control) technology enables precise and repeatable cuts in both laser and plasma cutting processes. This technology automates the steel processing process according to predetermined dimensions, minimizing process errors and increasing productivity. Steel Machining: The Future of CNC Laser and Plasma Technologies CNC laser and plasma technologies are constantly improving their effectiveness in steel processing processes. In the coming years, these technologies are expected to become more widespread in the steel industry and provide more innovative solutions.
Energy Policy Review – Turkey 2021
Notably, Turkey has seen considerable diversification of its energy mix in the past decade. In particular, renewable energy has staged impressive growth, with renewable electricity generation tripling in the past decade. The commissioning of Turkey’s first nuclear power facility in 2023 will further diversify the country’s fuel mix. Still, fossil fuels continue to drive Turkey’s economy, with a heavy dependency on imports, especially oil and gas (93% and 99%, respectively). Turkey has prioritised an expansion of domestic exploration and production to help reduce its oil and gas import dependency. However, given limits on upstream resources and with consideration to emissions reduction, Turkey should also place due consideration on cost-optimal demand-side measures such as efficiency improvements and fuel switching in the transport sector, which is still 98% reliant on oil. Moreover, there is still considerable scope for Turkey to target even more ambitious growth in renewables, not just in electricity, but also in other sectors such as heating. In addition, Turkey’s efforts to use more domestic energy resources to meet its consumption needs might interfere with efforts to decarbonise the energy sector, particularly as it relates to the government’s policy to use more low-quality domestic lignite in power generation. In a similar vein, as many countries around the world increasingly look toward net-zero greenhouse gas emissions by the middle of the century, Turkey should consider the impact of its energy policy – especially its focus on coal-fired generation – on investor sentiment, local air pollution and the longer-term emissions trajectory.

The Role of Low-Carbon Fuels in the Clean Energy Transitions of the Power Sector
Governments around the world are faced with the challenge of ensuring electricity security and meeting growing electricity uses while simultaneously cutting emissions. The significant increase in renewables and electrification of end-uses plays a central role in clean energy transitions. However, due to the variable nature of solar PV and wind, a secure and decarbonised power sector requires other flexible resources on a much larger scale than currently exists today. These include low-carbon dispatchable power plants, energy storage, demand response and transmission expansion. The availability and cost of these technologies depends on local conditions, social acceptance and policies. The possibility to combust high shares of low-carbon hydrogen and ammonia in fossil fuel power plants provides countries with an additional tool for decarbonising the power sector, while simultaneously maintaining all services of the existing fleet. The relevant technologies are progressing rapidly. Co-firing up to 20% of ammonia and over 90% of hydrogen has taken place successfully at small power plants, and larger-scale test projects with higher co-firing rates are under development. Ultimately, using large volumes of low-carbon hydrogen and ammonia in the power sector will help establish supply chains and drive down costs through economies of scale and technological improvements, thereby complementing and mutually reinforcing the use of low-carbon in fuels in other hard-to-abate sectors such as long-haul transport and industry.

What is the impact of increasing commodity and energy prices on solar PV, wind and biofuels?
Wind and solar PV Rising commodity prices have increased the cost of producing solar PV modules, wind turbines and biofuels worldwide. This situation has short-term implications for equipment manufacturers, project developers and policy makers. Higher prices for solar PV and wind equipment have reversed the cost reduction trend that the industry has seen for more than a decade and may delay the financing of some projects already in the pipeline. While rising input prices have already resulted in policy change on biofuels in several countries, demand for wind and solar PV remains strong, as reflected in recent auction participation and corporate purchasing, even with rising prices. While uncertainty remains as to how long commodity prices will continue their upswing, the impact of rising material costs on the profitability of the renewable energy industry could have long-term implications for the cost of clean energy transitions. Prices for many industrial materials, and freight costs, have been on an increasing trajectory since Q1 2021, pushing up wind turbine and solar PV costs. Since the beginning of 2020 the price of PV-grade polysilicon has more than quadrupled, steel has increased by 50%, copper by 60% and aluminium by 80%. In addition, freight fees have increased almost sixfold, resulting in additional costs for the geographically dispersed supply chain of renewables. The reversal of the long-term trend of decreasing costs is already visible in the prices of wind turbines and PV modules, which have increased by 10-25% depending on country and region, erasing two to three years of cost reductions since 2018 from technology improvements. The exception, however, is in People’s Republic of China (hereafter ‘China’) where wind turbine costs have continued to decrease in 2021, as demand declined following the 2020 deployment boom driven by the planned phase-out of subsidies. How do commodity prices affect the investment costs of solar PV and onshore wind? We estimate that key commodities and freight costs make up about 15% of total utility-scale solar PV and onshore wind investment costs. Solar PV’s largest cost component is the manufacturing and shipment of the module, which is directly affected by the price of polysilicon, steel and aluminium. Inverter and electrical installation costs depend on the price of copper, while all components are impacted by increasing freight rates. Steel contributes the most to the final cost of wind installations, as large quantities are used in manufacturing and construction of the tower, nacelle and mechanical equipment. Freight can make up to 6% of total onshore wind investment costs, as the transport of bulky elements with specialised ships is required. Read more Source: https://www.iea.org/
