Green Options

Storage is needed to harvest the full yield available from intermittent sources of energy like wind and solar. One of the options is compressed-air storage; till now only possible in underground caverns. But SustainX Energy Solutions; a Dartmouth College start-up  that got $4 million in VC funding from Polaris Venture Partners and Rockport Capital this year is working on compressing and storing air in cheap off-the-shelf shipping containers.

Over the next two years SustainX  will try and develop a way to cram 4 megawatt-hours worth of stored energy into each 40-foot long container and to reduce the energy that it currently takes to compress and release air by about 70%.

The goal? A renewable energy storage system with the portability and scalability of a battery and the economy and capacity of a cave. Make that a portable cave.

In a nearly unanimous vote just last summer, members of Maine’s Fox Island Electric Cooperative decided to invest in wind to power the island.

Today the $14.5 million Fox Islands Wind project officially goes on line with a ribbon-cutting event, marking the completion of Maine’s first island wind project; the largest community-owned wind project on the East Coast.

What would have been the Southern Hemisphere’s largest wind farm, a $2 billion NZD ($1.4 billion USD) and 630 MW wind farm in New Zealand, is not happening because New Zealand’s Environment Court says that it would ruin the surrounding landscape.

This project would have powered over a million homes and made a huge dent in New Zealand’s greenhouse gas emissions. It is not happening now because of a group of NIMBY activists and the Environment Court’s ruling.

This is a huge blow, in itself, to renewable and wind energy proponents, but it also brings concerns for future wind energy projects.

Maldives, one of the most beautiful nations on earth, held the artistic, theatrical event of an underwater government meeting last month, to try to bring more attention to the threats of climate change. Now, they are getting more practical but still grabbing headlines — they are looking to build a wind farm that will generate 40% of the island nation’s electricity needs.

The wind farm plans were announced earlier this week. The project will include 30 turbines and is expected to provide the nation with 75 MW of power, powering the capital city, their international airport, and more!

A couple weeks ago, I wrote about China’s new policy to focus on buying (almost entirely) “China-grown” wind turbines and wind turbine technologies with Chinese patents. That policy wasn’t a big hit internationally and China is back-tracking.

However, is it changing its stance out of international moral pressure or a major financial incentive (recent deal) in the US? And who is to benefit the most from this shift?

The huge project to build a $555 billion renewable energy “belt” in the Middle East and North Africa (MENA) region, funded largely by German companies, moved another step forward a few days ago.

The articles of association for the DESERTEC Industrial Initiative (DII) were signed by the joint venture group of 12 companies and the DESERTEC Foundation in Munich on October 30.

Additionally, a CEO for DII was appointed — Paul van Son.

Catch the Wind Ltd. of Virginia has just announced that its new Vindicator laser wind sensor has been deployed on a specialized buoy for a field test off Race Rocks Island in British Columbia.   If successful, the laser sensor would be part of the world’s first buoy-based wind power assessment system, which could shave millions off the cost of assessing conditions at potential sites for offshore wind turbines.

Conventional site assessments for large scale wind farms are done through the construction of a permanent offshore tower, which can cost up to $10 million.  Catch the Wind’s movable buoy-based system, called the WindSentinel, could virtually eliminate that expense and help open up sustainable offshore wind power to small communities, military bases, and other modestly scaled projects.

A-Power Energy Generation Systems won one aspect of the clean energy race and made history, as it will become the first Chinese manufacturer to export wind turbines to the United States. A-Power Energy Generation Systems and a consortium of Chinese and American companies — U.S. Renewable Energy Group, Cielo Wind Power, and the Shenyang Power Group — are planning to build a 600-megawatt wind farm in West Texas.

The project, which could power as many as 180,000 homes, will require 240 2.5-megawatt turbines and the farm will occupy 36,000 acres of land in West Texas. Nearly shovel ready, the construction effort is projected to create about 30 permanent jobs and 300 temporary ones. Ground-breaking on the wind farm is slated for March of 2010.

Kids enrolled in Wind for Schools shop classes in six Great Plains states (CO, ID, KS, MT, NE, SD) are learning hands-on to assist in assessment, design, and installation of small wind systems at their schools, with the goal of creating a knowledge base for wind energy within rural elementary and secondary schools through Wind Powering America.

The DOE is looking for proposals from wind companies who want to help out in expanding the program to six more states. You have till November 30 to get your bid in. And if you want to teach any aspects of this new shop class in wind, reach out to schools in these states.

Wind turbines?  Dontcha hate them!  Horrible things going round-and-round. Roundandroundandroundandround.  They make a lot of noise, and bits seem to keep on falling off them.  Dangerous.

Then there’s the NIMBY neighbours: “Oh, we don’t want one of those here,” they say.  “Renewable energy: yes.  Somewhere where it’s inconvenient: NO!”  It’s as though they think a wind-energy solution can be integrated into every house with minimal visual impact.

Well blow me down, it can!!
