Wind Turbine – Overview of Issues and in Turbine Technology

DUBLIN–()-  Wind turbines have begun to be used for electrical generation, having previously been used for agricultural and grinding purposes. Initial wind turbines had a very small capacity, as well as very low efficiency and performance standards. Wind turbines have gone through various technological advancements during the time they have been in use. Each and every component of a wind turbine has been upgraded to make wind power generation more reliable and efficient.

Multi-Megawatt (MW) wind turbines are currently in use, which are easily delivering an availability factor of 95% or higher. A number of technological changes have been made to wind turbines, all of which have resulted in the improved performance of wind power generation.

Rotor blades have seen improvements in blade aerodynamic profiles as well as improvements in blade material properties, resulting in the production of large rotor blades that have made wind turbines capable of capturing more wind power. Wind turbines used to be fitted with gearboxes with a higher gear ratio, which had high maintenance requirements and low reliability. Continue reading

Commercial Building Energy Storage Systems Revenue Will Surpass $7.5 Billion Annually by 2022

BOULDER, Colo.–()–The market for energy storage in commercial buildings is nascent and developing. Although one segment, energy storage systems for uninterruptible power supply (UPS) systems, is mature, the business models for the other two segments within this market – electrical energy storage (EES) systems and thermal energy storage (TES) systems – are still evolving. According to a recent report from Navigant Research, annual revenue from energy storage systems for commercial buildings will grow from $3.9 billion in 2013 to more than $7.5 billion in 2022.

“Today, there is less than 10 gigawatt-hours of cumulative energy storage capacity represented by all commercial building systems, and the vast majority of that capacity is frozen behind meters in UPS systems that are rarely, if ever, called upon”

“Today, there is less than 10 gigawatt-hours of cumulative energy storage capacity represented by all commercial building systems, and the vast majority of that capacity is frozen behind meters in UPS systems that are rarely, if ever, called upon,” says Sam Jaffe, senior research analyst with Navigant Research. “By 2022, such systems will represent a global cumulative capacity of more than 30 gigawatt-hours, most of which will be interacting with the power grids throughout the world on a daily basis.” Continue reading

“Green Curtain” Initiative: KYOCERA Greens Company Buildings and Saves Energy

KYOTO, Japan–()–As part of its traditional environmental protection and sustainability activities, Kyocera Corporation (NYSE:KYO)(TOKYO:6971) plants Green Curtains every spring at its sites in Japan and select Kyocera Group companies in other parts of the world. Through the hot summer, curtains of foliage are grown on trellises in front of office windows and walls at company sites. This not only provides shade but also shields the buildings from heat radiation — decreasing inside room temperatures by approximately 3.6 degrees Fahrenheit*, which contributes to a reduction of energy consumption from air conditioner usage.

New Component Manufacturing Furthers Efficiency Improvement for Siemens Gas Turbines

ERLANGEN, Germany–()–Siemens Energy has recently opened a facility in Charlottesville, Virginia for the innovative commercial production of airfoil ceramic cores for gas turbine blades and vanes using the TOMOSM technology, initially developed by Mikro Systems, Inc. The advancements are expected to improve the cooling capability of gas turbine blading, thus enabling higher levels of engine performance and efficiency for future Siemens Gas Turbines. This technology is available to Siemens as a part of the Technology License agreement with Mikro Systems.

With support from the U.S. Department of Energy (DOE) and the American Recovery and Reinvestment Act (ARRA), Mikro Systems was funded via Small Business Innovation Research (SBIR) grants. Mikro Systems and Siemens Energy partnered to develop the application of its patented Tomo-Lithographic Molding (TOMOSM) manufacturing technology to a range of gas turbine components.

Smart Grid Revenue in China Will Surpass $15 Billion a Year by 2020

BOULDER, Colo.–()–China is in the midst of its latest national development strategy, better known as the 12th Five-Year Guideline, which will continue through 2015. One of the Guideline’s primary goals is “strengthening the construction of [the] smart grid.” With the support of the government-owned State Grid Corporation of China, as well as many provinces and cities, this effort is rapidly progressing. According to a recent report from Navigant Research, annual revenue from smart grid deployments in China will reach $15.4 billion by 2020.

“The area of strongest smart grid growth in China will be transmission upgrades, anticipated to reach more than $72 billion in revenue by 2020 on a cumulative basis,” says Bob Lockhart, senior research analyst with Navigant Research. “Overall, smart grid development in China will generate $127 billion in cumulative revenue from 2012 to 2020.” Continue reading

Wind Energy Drives More Than Just Turbines

ge_windWind energy is the fastest-growing source of electricity production globally, and in the U.S., Texas ranks No. 1 for wind energy capacity. If Texas were a country, it would be sixth in the world.

Presently, Texas has 12,000 megawatts installed, which signifies a $20 billion investment in the state and creates jobs, said Elizabeth A. Salerno, director, Industry Data and Analysis, American Wind Energy Association.

“One megawatt can power 300 homes. One gigawatt can power 300,000 homes, and 12 gigawatts can power 3,600,000 homes. What many people do not understand is wind is a real power industry, and it is growing,” said Matt Guyette, chief marketing and strategy officer, GE Renewable Energy.

One indicator the industry is growing is the continual number of member companies joining the American Wind Energy Association, which today is close to 1,500.

“Ten years ago, there were less than 2,000 turbines, and today there are over 20,000. These are not your father’s turbines. These are efficient and are driving down the cost of electricity,” Guyette said.
