This article discusses future renewable energy technology. Topics include onshore wind, marine and wave technologies, and thermal energy storage systems. The REmap is an international reference case developed based on national plans of 40 countries. Table 1 summarizes generation of renewable energy technology by sector for the year 3013/2014. The data in the table is based on the REmap and the IRENA reference case. This article does not purport to be comprehensive, but should be of some help in understanding the technology that will be required to produce energy in the future.
Thermal energy storage systems
Crushed rock heat storage systems are emerging as a viable and cost-effective solution for long- duration heat storage. Crushed rock can be used for large-scale storage of heat and electricity, and can be reused by industries, buildings, and the grid. A 30-MW/130-MWh ETES prototype was recently launched in Hamburg by Siemens Gamesa Renewable Energy. These systems are relatively inexpensive and store heat at temperatures ranging from 180 to 750 degrees Celsius. The heat stored in these systems is converted back into power via a steam turbine.
Marine and wave technologies
While the U.S. has had the benefit of utility-scale wind and solar, Europe is making waves in the development of marine and wave technologies. In this article, we’ll take a look at how the technology can help us meet our energy needs. Our panel of experts includes Richard Ainsworth, project engineer for the European Marine Energy Center in Scotland, and George Bonner, director of the North Carolina Renewable Ocean Energy Program at the N.C. Coastal Studies Institute.
Onshore wind is a promising renewable energy technology for the future. Its cost is lower than traditional energy sources, and the average capacity of an onshore wind turbine is 3.9 megawatts. The wind turbines are … Read More
A number of renewable energy technologies are being explored today, including distributed generation, wind repowering, and recycling energy storage batteries. A key goal is to promote renewable energy technology development and the corresponding market growth. Financial incentives for renewable energy development and utilization are important, as they can lower up- front investment commitments and encourage design innovation. However, many obstacles still stand in the way of such development. In this article, we will discuss some key topics and their potential solutions.
The development of distributed generation in renewable energy technology has several key benefits. These include the ability to supply remote regions with power, solving local supply issues, ensuring back-up supply during grid failures, reducing peak loads, providing diverse energy products, combining cooling and heating capabilities, and improving integrated utilization efficiency. Additionally, distributed generation improves power factor and reduces power loss. As a result, distributed generation is an essential part of renewable energy technology development.
In this article, we’ll outline key factors for success. First, we’ll define distributed generation. By definition, distributed generation is electricity generated close to the point of use. Typically, this means wind, solar, or geothermal energy. Distributed generation is an important component of renewable energy technology development, and state and local governments can implement policies and programs that encourage the development of distributed generation, thereby helping to overcome market and regulatory barriers. The following resources will provide more information on distributed generation.
Wind repowering has numerous advantages over traditional forms of energy production. The new turbines have higher specific energy production than the older ones. Annual energy production increased by more than 2300 MWh between 2001 and 2003 and by almost ten thousand MWh between 2008 and 2015. This increase is attributable to the sharp increase in the performance of new turbines. … Read More
