Run-of-River Hydropower Set For Big Gains, Turbine Maker Predicts

Run-of-River Hydropower Set For Big Gains, Turbine Maker Predicts

written by Yale Environment 360

A type of hydroelectric technology known as “run-of-river” hydropower is set to grow 10-fold over the next decade, potentially becoming a $1.4 billion industry, according to Dutch turbine maker Tocardo International BV. Run-of-river hydropower stations redirect part of a waterway through a diversion to spin turbines and generate electricity.

Run-of-river is considered a more benign type of hydropower than large dam projects because it is a smaller-scale technology that doesn’t create large upstream reservoirs that flood ecosystems and disrupt a river’s natural flow.

Some conservation groups are concerned that problems with migratory fish passage and other environmental issues could outweigh the power-generating potential of run-of-river hydro projects.  Tocardo notes, however, that flow monitoring and ecosystem protection strategies, such as fish ladders, are an important part of run-of-river hydropower deployment. The company implemented its first project to harness tidal streams at Den Oever, Holland, and it has been generating power for five years.

New Turbine for Low Wind Sites

written by Walter Wang

Wind density is an issue for the wind power industry. The windier the site, the higher the energy output will be. But a new product, launched at the EWEA 2012 in Copenhagen, promises to achieve maximum returns from low-wind sites. The makers hope it will become a benchmark in the industry thanks to its low power

Interest in Small Wind Energy Grows

written by Walter Wang

Small wind generation with vertical axis turbines, also known as VAWT, is one of the most exciting recent developments in small scale alternative energy generation.

Last week we caught wind that Sauer Energy, which develops VAWT systems, has attracted huge interest

Wind Farms with Compressed Air Energy Storage

written by 2GreenEnergy

I’ve added a hot new business plan to the list I’m now featuring. I spoke yesterday with Joe Speace, CEO of “Project Renewable Energy” near Kansas City, whose raising capital for a wind farm that will feature compressed air energy storage (CAES). This looks quite strong.

Storage will be a big deal soon, as the

Sauer Energy Unveils Prototype Vertical-Axis Wind Turbine

written by Earth & Industry

The image most people have in their minds when they think of wind turbines are the big, white horizontal-axis wind turbines with their massive blades spinning slowly on a wind-swept plain. But the clean energy revolution–if, in fact, it is a revolution–has room for more than just one design of wind turbine.

But vertical-axis wind turbines (VAWTs) are poised to

CEC Approves First Utility Solar Project in 20 Years

written by Solar Calfinder

After years of delay, things are finally heating up for large-scale solar thermal power plants in California’s remote deserts. In the last month, a California Energy Commission (CEC) siting committee has recommended at least five solar plants for approval. Last week the first of these projects gained official go-ahead from the agency. The Beacon Solar Energy project

Australia to Build Largest Wind Farm in Southern Hemisphere

written by Yale Environment 360

Australian officials plan to build a 140-turbine wind farm in Victoria, the nation’s most densely populated state, by 2013, a billion-dollar project that would be the largest in the Southern hemisphere. The wind farm will provide enough electricity for 220,000 homes and is key to the nation’s new target of meeting 20 percent of its energy needs with renewable

What Wind Turbine 2.0 Will Look Like

written by

I am coming to the conclusion that the wind turbines of today — hundreds of feet tall, sporting three blades, clustered in the cornfields like rotary clubs — will soon go the way of the Model T. Good for their day, but we’ve moved on.

I explored alternative designs in wind power for my latest “Innovate” column in Sierra magazine, and can report that 31 flavors of turbines are poised to engulf the plain ol’ vanilla version we know so well. It isn’t that anything’s so wrong with Old Reliable; it’s more that there’s categories of wind that a giant whirligig just can’t use.

Windation Promises Bird-Free Rooftop Wind Energy

written by

Windation Energy Systems has developed an urban-wind rooftop turbine designed for commercial and industrial buildings. Billed as “permit-ready” and “bird safe,” Windation’s 5 kW turbine resembles a commercial AC unit and leverages a proprietary vacuum system to purportedly amplify wind speed and boost energy output.  The company’s first installation is expected this quarter in Palo Alto, CA.

CleanTechies aimed four questions at CEO and founder Mark Sheikhrezai.

Turkish wind energy growing fast with feed-in-tariff in the pipeline

written by Levent Bas

The Turkish Statistical Institute announced that the Turkish economy shrank 13.8% and that the unemployment rate increased to 14.9% in the first quarter. Despite these difficult economic conditions, the Turkish wind industry is still one of the fastest growing industries in the country. One reason is that Turkey may face electricity shortages in the near future, furthermore Turkey has just ratified [the] Kyoto agreement which is going to result in carbon emission reduction targets for the post 2013 period.

Among other renewable resources, wind has been the most popular and most approachable power source in the last four years. The use of wind power started around 1,000-1,200 AD in Anatolia, as early as in other European countries. However, Turkey’s development throughout the centuries has not been as fast as that of its counterparts. At the time when Turkey installed its first 0.5 MW wind turbine in Izmir in 1998, Germany had already installed almost 3,000 MW.
