These structures are developed according to the needs of each project and each partner, thus ensuring the quality of the projects from their conception to their operation.
Acreditamos que o desenvolvimento de projetos é um processo integrado, cujo funcionamento é muito mais eficiente quando há sinergia entre todas as fases.
The Development Engineering area aims to allow Natural Energia to continue to participate in developing their projects, even after equity structuring.
Our Implementation Engineering area is responsible for the efficient execution of the project, from planning to construction and commissioning. The team coordinates construction, oversees the installation of electrical equipment and systems, manages technical documentation, and troubleshoots, ensures safety, and implements sustainable practices.
Wind turbines transform the wind’s kinetic energy into power.
The wind is a mass of air in movement. This movement is caused by differences between temperature and pressure over the land surface due to solar radiation. Therefore, wind power uses a renewable resource as fuel and doesn´t pollute the air.
The development of the technology brought us several types and shapes of wind turbines, with different axis of vertical and horizontal orientations, different tower heights, and the size or number of blades.
Nowadays, the most used ones have horizontal axis with three blades and can be 525 feet high. The diameters of the blades can hundreds of feet wide.
Solar power plants
Solar energy is the most basic and fundamental way to sustain life on Earth. Almost all power sources derive in some way from it. Processes such as photosynthesis, the rainfall cycle, and global circulation cells all rely on solar radiation.
Despite these characteristics, only recently have humans started using this radiation for electricity generation. Today there are two leading technologies to convert solar energy into electric energy. They are photovoltaic (PV) energy and solar concentrating power (CSP).
Photovoltaic Energy
This type of energy is generated through panels that produce tension and specific electric currents when under radiation. These panels can be plugged in series or parallel to create greater tension and currents. Photovoltaic modules can be made from different materials, silicon being the most used for large-scale power plant applications.
The connection of these panels to the grid is made through a frequency inverter, which transforms the energy produced in direct current to alternating current, and controls the power injected into the grid.
Photovoltaic energy allows several applications, from powering homes and buildings to reducing energy consumption from the grid, isolated systems with no power distribution grid, or large plants connected to the transmission grid. Natural Energia works on the development of large-scale projects connected to the power transmission grid or on customized solutions for large consumers.
Concentrated Solar Energy (CSP)
The concentrated solar energy consists in several mirror panels which reflect the sun radiation in a specific point in where a fluid runs inside to be heated. This fluid is heated in very high temperatures and used to transform water into pressurized steam. This steam is then used to run a steam turbine and generate electric energy.
There are two types of power plants that uses concentrated solar energy. One utilizes flat straight mirrors to reflect the sun´s rays to a tower in the center of the powerplant in which the fluid to be heated runs. The other uses concave mirrors that concentrate the sun rays in a focal point in which runs the fluid to be heated.
This technology, differently from the photovoltaic that allows small scale applications, demands huge areas and great amount of investment in infrastructure.
Natural gas plants, unlike other types of power plants which run over fossil fuels, allow easy and quick control over power generation with very low carbon emission levels. In addition, natural gas plants utilize small sites and can be installed near large cities, optimizing the whole infrastructure required e providing relief to the transmission system, which will ultimately provide energy supply security.
Natural gas power plants figure as a clean alternative to assure grid stability and safety.
Natural gas power plants are an essential energy source and a key fuel to make the energy transition possible. Moreover, due to the low level of carbon emissions, natural gas power plants can supply clean energy at the time, in the at the rate, and where the electrical system needs it. In this way, it is an essential ally for inserting renewable energies into the Brazilian electrical system. Furthermore, it is a firm form of power with a certain flexibility that can compensate for the natural intermittency of other renewable sources.
Hydrogen is an abundant chemical element in nature and can be obtained from renewable sources, such as water, through different processes.
One of the processes of obtaining hydrogen is through electrolysis, a process in which H2 is obtained from separating of the water molecule (H2O) using an energy source.
One of the significant advantages of hydrogen as an energy source is that its combustion does not produce emissions of greenhouse gases, such as carbon dioxide, which is mainly responsible for global warming. In this process, O2 can also be obtained as a subproduct.
In addition, the hydrogen and subproducts can be used in many sectors such as transportation, energy storage, or even as raw material for fertilizers and steel.
“The transmission lines do not store electrons. The amount of energy being generated at a specific time must be equal to the amount of energy being consumed.”
With the growing importance of Wind and Solar generation, Batteries for energy storage are now playing a crucial role in the electricity market by allowing the efficient storage for arbitrage and release of electrical energy for ancillary services. Right now, the US, Europe and Asia are seeing an exponential growth in the installation of such systems.
Among various storage technologies, lithium-ion batteries have gained significant attention due to their high energy density, long cycle life, and excellent charge-discharge efficiency.
Lithium-ion batteries store energy through the movement of lithium ions between two electrodes (anode and cathode) during charging and discharging. The energy stored in these batteries can be used in various applications, such as grid energy storage, electric vehicles, and consumer electronics.
In the electricity market, lithium-ion batteries are particularly beneficial for balancing supply and demand, integrating renewable energy sources, and enhancing grid stability. They help address the intermittent nature of renewable energy sources like solar and wind by storing
excess energy generated during peak production times and releasing it when demand is high, or production is low. This not only improves the overall reliability of the power grid but also reduces greenhouse gas emissions by enabling a higher penetration of clean energy sources.
Overall, lithium-ion batteries for energy storage have become an essential component in the transition towards a more sustainable and efficient electricity market.
The growing adoption of electric vehicles (EVs) has increased the demand for efficient and accessible charging infrastructure. EV chargers can be broadly divided into two categories: DC chargers, typically found on roadways, and AC chargers, commonly installed at homes and businesses. Each type of charger has its advantages and is designed to cater to specific charging requirements.
Direct current (DC) chargers, also known as fast chargers, are predominantly found along highways, in public parking lots, and at dedicated charging stations. These chargers are designed to facilitate long-distance travel by providing high-power charging that can replenish an EV’s battery in a matter of minutes rather than hours.
Due to their high-power output and advanced technology, DC chargers are generally more expensive than AC chargers. However, their efficiency and convenience make them a vital component of the EV charging network, especially for long-distance travelers.
On the other hand, alternating current (AC) chargers are the most common type of EV chargers, suitable for homes and businesses. They offer a cost-effective and convenient way to charge electric vehicles during downtime, such as overnight or while at work.
The development and expansion of EV charging infrastructure present numerous opportunities for growth and innovation within the electric vehicle market. As demand for charging infrastructure surges, there is significant potential for new players to enter the market,
offering innovative charging solutions, technologies, and services.
This growth also creates opportunities for collaboration between utility companies, charging network providers, real estate developers, and local governments to ensure the seamless integration of charging infrastructure in urban planning and development.
By seizing these opportunities, stakeholders across the spectrum can help shape the future of mobility and work together to create a greener, more efficient world.
