Solar trackers offer significant advantages for renewable energy generation, leading to an increase in power output of approximately 30 to 40 percent, thus creating opportunities in new markets for solar power. Nonetheless, solar trackers come with notable drawbacks. Unlike static solar panels with long-lasting warranties and low maintenance requirements, solar trackers possess shorter warranties and necessitate one or more actuators for panel movement.

These mobile components not only elevate installation expenses and decrease reliability but also introduce energy consumption, which is unnecessary in passive systems. Furthermore, computer-based algorithm solar trackers, though more costly and demanding additional maintenance, face obsolescence sooner compared to static solar panels due to their reliance on rapidly advancing electronic components that may be challenging to replace within short timeframes.  Curious how solar PV panels get optimal sunlight exposure? It’s thanks to solar trackers!

Solar tracking systems adjust the direction of panels to align with the sun, ensuring they remain perpendicular to its rays. This minimizes reflection and maximizes energy capture, as a narrower angle of incidence leads to higher energy generation. While commonly used for positioning solar photovoltaic panels, solar trackers are also valuable for space telescopes. Want to know how these systems work? Stay tuned as we explain everything about solar trackers in this blog.

Let’s Look Into The Working:

 A solar tracker operates as an auto-tracking control system, comprising PV cells, a PLC, signal processing units, sensors, electromagnetic and mechanical motion control modules, and power supply systems. When sunlight intensity increases, the panel activates and transmits this information to the sensors, which then relay it to the PLC. The PLC processes this data and generates an output that directs the motor to rotate the panel towards the sun. A solar panel aligned precisely perpendicular to the sun produces more power than one that is not.

Types of Solar Trackers:

Types of Solar Trackers

Based on their working method, solar trackers can be classified as:

1. Passive Tracking Devices: Passive solar trackers operate without an additional energy source. They move by using the sun’s heat to expand a gas inside the system, which creates mechanical movement of the PV panels.

– When one side of the tracker heats up, the gas expands, causing a piston to rise and tilt the panel toward the sunny side.

– As the sun sets and the gas cools, it compresses again, allowing the panels to rotate back.

2. Active Tracking Devices: Most solar tracking systems are active solar trackers. These systems have an energy supply to operate a motor or mechanical device, allowing them to directly tilt the attached solar panels.

– Active solar trackers use light sensors to determine sunlight intensity.

– The system then calculates the optimal orientation for the solar modules.

– These trackers are best suited for large and complex solar arrays.

3. Open Loop Trackers: using controlled algorithms or simple timing systems, which are further divided into:

  – Timed Trackers: Timed open loop sun trackers adjust the position of solar panels based on a preset schedule rather than real-time feedback from sensors. They use a clock or timer to trigger movements at specific intervals, following a pre-calculated path that aligns with the sun’s position throughout the day. This type of tracker is simpler, more reliable, and cost-effective compared to closed loop systems, but may be less precise in varying environmental conditions. Ideal for budget-conscious projects in areas with consistent sunlight, they provide a balance between improved solar energy capture and system complexity.

 – Altitude/Azimuth Trackers: Azimuth open loop sun trackers adjust the horizontal angle (azimuth) of solar panels to follow the sun’s east-to-west movement throughout the day. They operate based on pre-programmed algorithms or schedules, without using real-time sensors. These trackers are simpler and more cost-effective than sensor-based systems, providing moderate efficiency improvements while being easier to maintain. Ideal for residential and commercial solar installations, they offer a balance between enhanced energy capture and system simplicity.

Based on their motion or directional flexibility, solar trackers can be categorized as:

1.Single-Axis Solar Trackers: A single-axis tracker rotates solar panels around one axis, typically aligned in the North-South direction. This allows the panels to follow the sun’s movement from East to West as it rises and sets. By enabling the panels to track the sun, it enhances the system’s efficiency without needing additional PV modules. These trackers are best installed on flat, sunny, and dry land. Although the initial installation cost is high, the increase in productivity can quickly offset these expenses.

2.Dual-Axis Solar Trackers: A dual-axis tracker allows solar panels to rotate on two axes simultaneously, providing movement in all directions: North, South, East, and West. This type of tracker is suitable for some commercial properties and is designed to maximize solar energy generation throughout the year. Using algorithms and sensors, dual-axis trackers can adjust to seasonal changes and the varying height of the sun, in addition to its daily motion.

Benefits of a Solar Tracker:

1. Increased Productivity: Solar trackers boost the productivity of solar panels by ensuring higher direct sunlight exposure. Productivity gains depend on the geographic location of the installation.

2. Simple and Eco-friendly Energy: These devices conveniently track the sun, resulting in better energy output and providing a sustainable power source.

3. Land Optimization: Solar trackers optimize land use by generating more electricity compared to non-tracking systems while occupying the same amount of space.

4. Easy Monitoring: You can monitor your solar tracking system’s performance directly from your PC.

But are there any drawbacks to using a solar panel tracker? Let’s find out!

Limitations of Solar Tracker

Limitations of Solar Tracker:

1. High Cost: Solar tracking devices are more expensive due to their moving parts, resulting in higher initial costs.

2. Increased Maintenance: These systems require more maintenance, though the extent depends on the type and quality of the tracking system.

3. Site Preparation Requirements: Installation of solar tracking systems involves significant site preparation, including additional trenching for wiring and grading.

4. Weather Constraints: Solar trackers are less effective in snowy weather and are most beneficial in hot climates.

Derived from organic materials like biomass, biofuels offer a cleaner alternative to fossil fuels, mitigating greenhouse gas emissions and reducing reliance on finite resources. Through advanced technologies, such as biochemical conversion and microbial fuel cells, biomass residues and waste are efficiently transformed into biofuels, ensuring optimal resource utilization. From bioethanol to biodiesel, these fuels power vehicles, heat homes, and generate electricity, driving a shift towards a greener future. Embracing biofuels not only fosters energy security but also fosters economic growth while safeguarding the environment for generations to come.

A Solution to Modern Energy Challenges

In light of the energy crisis of the 1970s, numerous countries have shown a keen interest in developing biomass as a viable fuel source. While there was a decrease in enthusiasm for biomass energy in recent times due to the affordability of fossil energy following technological advancements, the pressing concerns related to high greenhouse gas emissions, hazardous air pollution, fluctuating fossil fuel prices, and the escalating demand for global transportation fuels have spurred significant research endeavors in the field of bioenergy. 

Bioenergy refers to energy derived from any fuel that originates from biomass, a renewable resource that is being increasingly recognized as a potential alternative feedstock to ensure sustainable energy production in the future. 

Traditionally, biomass in the form of firewood has historically been utilized for providing energy to humans through direct combustion. In industrialized nations, a diverse array of feedstocks, such as agricultural and forestry residues, building and industrial waste, and municipal solid waste (MSW), are readily available for biofuel production.

These biofuels, produced from such feedstocks, are classified as second-generation biofuels. Unlike first-generation biofuels, which are derived from edible food crops like sugarcane, wheat, barley, corn, potato, soybean, sunflower, and coconut, second-generation biofuels are derived from lignocellulosic materials such as jatropha, cassava, switchgrass, wood, and straw, along with biomass residues. 

Harnessing Biomass Residues for Sustainable Biofuels

Distinct from biomass deliberately grown for energy production, biomass residues and waste are produced as by-products throughout the cultivation, processing, and utilization of desired raw materials. These residues are classified into primary, secondary, and tertiary groups. Primary residues, such as corn stalks and straw, originate from the cultivation of food crops and forestry products. Secondary residues are created during the processing of food crops into end products, such as wood chips and rice hulls. 

Tertiary residues emerge after the consumption of biomass-based products and may present as municipal solid waste (MSW), sewage sludge, or wastewater. These materials undergo conversion processes leading to a variety of bioenergy forms, such as syngas, bio-oil, biochar, electricity, biogas, bioethanol, biohydrogen, and biodiesel. Wood and agricultural residues, waste cooking oils, and microalgae biomass have demonstrated potential as valuable resources. Wood and agricultural residues, such as sawdust and corn stover, are viable options for use as feedstocks in the production of biofuels. 

For instance, sawmill waste can be employed as boiler fuel or for the production of ethanol. Straw, a significant biomass source in China, is derived from harvested food crops such as rice and wheat. Corn stover shows promise for bio-butanol production, while residues from sugarcane, including bagasse and leaves, present opportunities for ethanol and biochar production. Additionally, palm kernel press cake, a by-product of palm oil extraction, can undergo fermentation to generate bioethanol. 

Utilized cooking oils, such as used cooking oils, serve as a cost-effective resource for the production of biodiesel, resulting in a substantial reduction in material expenses. The application of waste oils not only decreases production costs but also tackles the environmental concerns linked to the disposal of substantial volumes of used frying oils. 

The utilization of biodiesel blends derived from waste oils and diesel in engines can be implemented without significant alterations. Including both macroalgae and microalgae, the group known as microalgae presents a significant potential as a source of oil due to their notable lipid storage capabilities and rapid growth rates. Microalgae, specifically, have garnered interest for their potential as a feedstock for biofuels, as they do not require agricultural land or freshwater resources. 

Once the desired products, such as oils, are extracted from microalgae biomass, the remaining biomass can be utilized for the production of biofuels.

• Combustion directly burns organic waste to produce heat and electricity.

2. Biochemical Conversion:

Biochemical conversion processes includes:

• Anaerobic digestion is a biological process that breaks down organic matter in the absence of oxygen, producing biogas (a mixture of methane and carbon dioxide) and digestate (a nutrient-rich substance). This technology is widely used for managing agricultural waste, sewage sludge, and food waste. The produced biogas can be used for heating, electricity generation, or upgraded to biomethane for use as a vehicle fuel.
• Fermentation process is used to produce bioethanol from sugar and starch-rich crops. This process involves the breakdown of carbohydrates by enzymes and microorganisms into ethanol and carbon dioxide. Bioethanol is a renewable fuel that can be blended with gasoline or used as a feedstock for producing chemicals.
• Photobiological hydrogen production is a process observed in certain biomass, such as microalgae, which naturally generate hydrogen gas in the presence of light.

3. Microbial Fuel Cells (MFCs)

A promising recent technology for converting biomass into electricity involves Microbial Fuel Cells (MFCs). MFC technology utilizes electrogenic bacteria to generate bioelectricity by converting organic substrates under anaerobic conditions. 

Typically, MFCs consist of two chambers separated by a proton exchange membrane, with a biotic anode and an abiotic cathode. This setup allows MFCs to simultaneously treat various types of waste, such as food waste, household food waste, and municipal solid waste (MSW), while producing electricity, offering a novel source of renewable energy. 

The current and power density generated by MFCs can be influenced by operational factors like temperature, substrate concentration, pH, loading rate, microbial activity, hydraulic retention time, and the presence of a static magnetic field. Additionally, research has focused on optimizing electrode materials, architectures, cost-effectiveness, and membrane characteristics to enhance electricity generation in MFCs. Studies have shown that using Ti-TiO2 electrodes can yield significantly higher power density compared to Pt electrodes, and employing food residue biomass as a substrate can further boost MFC performance. Overall, MFCs hold great potential as a green and sustainable process, offering new opportunities for bioelectricity generation.

4. Transesterification 

Biomass-derived biofuels often exhibit high viscosity, low energy density, and polyunsaturated characteristics, which can be addressed through various pretreatment methods, with transesterification emerging as the most promising. Transesterification involves the conversion of fats and oils into esters and glycerol in the presence of catalysts. The resulting fatty acid methyl ester (FAME) boasts physical characteristics comparable to commercial petroleum fuels, while the by-product glycerol holds commercial value.

Converting organic waste into energy resources represents a crucial step towards a sustainable and circular economy. By leveraging advanced conversion technologies, we can mitigate environmental impacts, enhance energy security, and derive economic benefits from waste materials. Continued research, innovation, and supportive policies are essential to overcome the challenges and fully realize the potential of waste-to-energy solutions.

This source has been utilized for heating and/or generating electricity for many centuries. In contrast to wind and solar power, geothermal power plants generate a consistent amount of energy regardless of weather conditions. These resources are believed to be abundant enough to meet the energy demands of humanity.

Geothermal power refers to electrical power that is generated from geothermal power plants. It is classified as a renewable energy source due to the minimal heat extraction rates in comparison to the Earth’s heat capacity. On average, geothermal electric stations emit approximately 45 grams of carbon dioxide per kilowatt-hour of electricity, which is less than 5 percent of the emissions of coal-fired plants. Traditionally, geothermal electric plants were constructed on the peripheries of tectonic plates where high-temperature geothermal resources were close to the surface.

The advancement of binary cycle power plants and enhancements in drilling and extraction technology have allowed for improved geothermal systems to be implemented across a broader geographical range. This blog delves into the different types of geothermal power plants, their working principles, and their benefits, with examples from around the world showcasing their efficacy and impact.

Dry Steam Power Plants

Dry steam power plants are the oldest and simplest type of geothermal power plants, directly utilizing geothermal steam from underground reservoirs to generate electricity. These plants extract steam through wells and direct it to turbines, which spin and drive generators to produce electricity. After passing through the turbine, the steam is condensed into water and reinjected into the reservoir to maintain pressure and sustainability.

Dry steam plants are highly efficient and emit very low levels of greenhouse gases. However, they are geographically limited to areas with specific geothermal resources that produce dry steam. A prime example is The Geysers in California, USA, the largest dry steam geothermal complex in the world, generating around 900 MW of electricity since the 1960s. Here are the examples in separate paragraphs:

1. Larderello Geothermal Complex, Italy:

 Located in Tuscany, Italy, the Larderello Geothermal Complex has a capacity of approximately 800 MW. This complex is one of the world’s oldest geothermal power plants, with the first plant constructed in 1911. It harnesses the abundant dry steam resources of the region to generate electricity. Larderello has been a pioneer in geothermal energy, significantly contributing to renewable power in Italy for over a century.

2. Matsukawa Geothermal Power Plant, Japan:

 The Matsukawa Geothermal Power Plant, located in Iwate Prefecture, Japan, has a capacity of around 23.5 MW. Operational since 1966, Matsukawa is Japan’s first geothermal power plant. It utilizes dry steam extracted from geothermal wells to generate electricity, showcasing the feasibility and reliability of geothermal energy in the region.

3. Cerro Prieto Geothermal Power Station, Mexico:

 Situated in Baja California, Mexico, the Cerro Prieto Geothermal Power Station has a capacity of over 720 MW. While primarily a flash steam facility, parts of the Cerro Prieto complex use dry steam technology. It is one of the largest geothermal power complexes in the world and plays a crucial role in providing renewable energy to Mexico, illustrating the diverse applications of geothermal power technology.

Flash steam power plants

Flash steam power plants are the most common type of geothermal power plants, utilizing high-pressure hot water from deep geothermal reservoirs to generate electricity. The hot water, typically between 150°C and 370°C, is extracted and directed into a flash tank where a sudden drop in pressure causes some of the water to “flash” into steam. This steam drives a turbine connected to a generator, producing electricity.

After passing through the turbine, the steam is condensed back into water and reinjected into the reservoir to sustain the resource. Flash steam plants are highly efficient and scalable, making them suitable for large-scale power generation in areas with high-temperature geothermal resources.

Here are a few examples of flash steam power plants:

1. Wairakei Power Station, New Zealand:

Located in the Taupo Volcanic Zone, the Wairakei Power Station is one of the earliest and most well-known geothermal power plants utilizing flash steam technology. Operational since 1958, it has a capacity of approximately 180 MW. The plant uses high-pressure hot water from the geothermal field, flashing it into steam to drive turbines and generate electricity.

2. Makiling-Banahaw (Mak-Ban) Geothermal Power Plant, Philippines:

 Situated in the Laguna and Batangas provinces, the Makiling-Banahaw Geothermal Power Plant, also known as Mak-Ban, has a capacity of around 458 MW. This plant uses flash steam technology to harness the geothermal resources of the region, producing significant amounts of electricity and contributing to the Philippines’ renewable energy supply.

3. Ahuachapán Geothermal Power Plant, El Salvador:

 Located in the western part of El Salvador, the Ahuachapán Geothermal Power Plant has been operational since the 1970s with a capacity of about 95 MW. It employs flash steam technology to convert high-pressure geothermal fluids into steam, which then drives turbines to generate electricity. This plant is a critical component of El Salvador’s renewable energy infrastructure.

These examples illustrate the widespread use and effectiveness of flash steam power plants in various parts of the world, contributing significantly to the global renewable energy landscape.

Binary Cycle Power Plants

Binary cycle power plants are designed to harness geothermal power plants from lower temperature geothermal resources, typically ranging from 85°C to 170°C. Unlike dry steam and flash steam plants, which require high-temperature steam or water, binary cycle plants can operate efficiently with moderate geothermal heat sources, expanding the potential for geothermal energy use. Binary cycle power plants work by extracting hot water or steam from geothermal reservoirs through wells, typically at temperatures between 85°C and 170°C.

This geothermal fluid is insufficient for direct steam generation but ideal for binary cycle systems. The fluid passes through a heat exchanger, transferring its heat to a secondary working fluid with a lower boiling point, such as isobutane or isopentane. The secondary fluid vaporizes and, under high pressure, drives a turbine connected to a generator, producing electricity. Afterward, the vaporized secondary fluid is cooled and condensed back into liquid form in a condenser, then recycled to the heat exchanger in a closed-loop system.

The cooled geothermal fluid is reinjected into the reservoir to maintain pressure and resource sustainability. Binary cycle plants efficiently utilize lower temperature resources, have lower emissions, and provide operational flexibility due to the controlled properties of the secondary fluid.

Examples:

1. Chena Hot Springs, Alaska, USA:

Chena Hot Springs features a binary cycle power plant that operates with geothermal fluids at temperatures as low as 74°C, one of the lowest temperature geothermal power plants in the world. This plant demonstrates the capability of binary cycle technology to generate electricity in cold regions with moderate geothermal resources.

2. Svartsengi Power Station, Iceland:

The Svartsengi Power Station in Iceland primarily uses flash steam technology but also incorporates binary cycle technology to optimize energy extraction from its geothermal resources. It produces both electricity and hot water for district heating, showcasing the hybrid application of geothermal technologies.

3. Dara Jalil Geothermal Power Plant, Turkey:

 The Dara Jalil plant in Turkey utilizes binary cycle technology to generate electricity from moderate temperature geothermal resources. This plant is a key example of how binary cycle systems can effectively harness geothermal energy in regions with suitable resources, contributing to Turkey’s renewable energy mix.

Binary cycle power plants represent a versatile and efficient approach to geothermal energy, capable of exploiting lower temperature geothermal resources and providing a reliable source of renewable energy in diverse geographical locations.
Incorporating geothermal power plants into the energy sector presents a sustainable, dependable, and economically advantageous answer to the increasing global energy demands. Due to their low environmental footprint and ability to offer a continuous energy source, they emerge as a crucial element of the renewable energy portfolio.

Instances from nations such as Iceland, the United States, Kenya, and Indonesia showcase the significant influence of geothermal power.
