Storing Renewable Energy in Boxes of Air

Susan Kraemer — Fri, 20 Nov 2009 19:33:55 +0000

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 to 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.

Best Counterargument to Price on Carbon Hurting Jobs?

Scott Cooney — Fri, 20 Nov 2009 17:25:19 +0000

At yesterday’s Sustainable Industries Economic Forum, keynote presenter Paul Hawken was asked, “What is the best counterargument to the argument that carbon caps will raise energy costs and hurt our economy?” In typical Hawken style, his earlier speech was well done, inspiring and insightful. In typical Hawken style, his off-the-cuff answers to audience questions was where he really shone. And this answer was perhaps his shining moment of the day.

Paul Hawken on Being a ‘Doomer’

Scott Cooney — Fri, 20 Nov 2009 17:09:11 +0000

During yesterday’s Sustainable Industries Economic Forum, keynote speaker Paul Hawken suggested that it will take a somewhat monumental effort to get back to 350 ppm in our atmosphere (we’re at 387 right now). His list was daunting. We’d need one new olympic sized pool of bioalgae fuel production every second for 25 years, for example. He said that while being a ‘doomer’ has a negative connotation, the facts are the facts, and that there is a role for this kind of startling statistic. An audience member asked the question that was on all our minds: “It seems untenable. Do you have hope that this can actually happen?”

Quick-Charge Batteries Get a Boost from Defective Carbon Nanotubes

Tina Casey — Fri, 20 Nov 2009 13:08:32 +0000

Researchers at the University of San Diego have discovered that carbon nanotubes don’t have to be perfect to do a better job. The team of UCSD Professor Prabhakar Bandaru and grad student Mark Hoefer found that defective carbon nanotubes actually store energy more effectively than their unflawed counterparts.

The effect, which was originally studied at UCSD by grad student Jeff Nichols, rests in the creation of just the right amount of defects - enough to create additional charge sites on the nanotube, but not enough to break down its electrical conductivity. Though it’s a long way from commercialization, the breakthrough brings us one step closer to the Holy Grail of the electric car, and to the entire battery operated sustainable infrastructure of the future: a genuine quick-charging, long lasting battery.

Asia Light Years Ahead of the US in Clean Tech Investment — Financial and Economic Consequences

Zachary Shahan — Fri, 20 Nov 2009 11:50:06 +0000

Asia is investing hundreds of billions of dollars more than the US in clean technology, according to a new report by two research institutions. In the future, the US may be importing trillions of dollars of needed clean technology (and losing countless jobs to Asia) as a result.

In total, the report showed that China, Japan, and South Korea will invest about $509 billion in clean tech over the next 5 years, whereas the US (with our greenest President in decades, maybe ever) is only expected to invest $172 billion (about 3 times less) — this is assuming the climate and energy legislation in Congress passes.

If the US were to invest the same percentage of its Gross Domestic Product (GDP) as South Korea, it would invest almost $140 billion per year ($700 billion over this five year period)! Compared to China, the anticipated per-GDP investment ratio is 1:4 (US to China).

In 2008, Japan almost matched US R&D spending on energy and achieved almost the same number of international clean energy patents despite having dramatically lower GDP.

The financial investment is not the only thing giving these countries a major advantage in this field, though.

Altus Air Force Base is Flying High on New Green Award

Tina Casey — Thu, 19 Nov 2009 23:47:24 +0000

Off they go into the wild green yonder: the 97th Air Mobility Wing at Altus Air Force Base in Oklahoma has just earned the top “Green” rating from the Air Force’s Environmental, Safety and Occupational Health compliance program.

The 97th spent months prepping for its evaluation and earned a “you knocked our socks off” comment from the ESOHCAMP program manager, but that’s not the only sustainability feather in Altus’s cap. The base is also home to one of the Air Force’s premier green remediation sites.

New Report Forecasts Solar Boom in NC — “Growing Solar in North Carolina”

Zachary Shahan — Thu, 19 Nov 2009 21:26:23 +0000

A new report by Environment North Carolina’s Research and Policy Center, “Growing Solar in North Carolina,” found that North Carolina (home of my UNC Tar Heels) could be a solar power giant soon.

The new report found that North Carolina has a lot of solar energy potential due to its “vast” solar energy intensity (which is nearly as much as Florida’s) combined with other economic, policy and technological factors.

Top ARPA-E Funding Goes to Renewable Storage in Liquid “Battery”

Susan Kraemer — Thu, 19 Nov 2009 18:30:08 +0000

DOE’s new renewable energy Venture Capital unit ARPA-E has just funded an entirely new kind of liquid battery innovation from MIT professor Donald Sadoway, that works like an aluminum plant running in reverse; producing power instead of consuming it.

Under the ARPA-E program at the DOE, the Obama administration has provided record-setting funding for advanced breakthroughs in renewable energy technology - that could propel America to the front of the post-oil age economy.

Just 37 technologies were selected for their potential transformational impact in the world, out of 3,600 applicants. Of the 37 winners; Sadaway’s has received the most funding; with $7 million.

Nike’s Lorrie Vogel on Closing the Loop. Part 2- The Human Impact

Susanna Schick — Wed, 18 Nov 2009 16:00:09 +0000

Laura Kurgan, Chris Jordan, Lorrie Vogel and Assaf Biderman - Pop!Tech 2009 - Camden, ME

In Part One, Lorrie Vogel explained some of the work Nike is doing to increase recycled and organic content in their products. Our conversation continues with discussing how Nike designers are encouraged to use sustainable principles in their work.

SS: You mentioned something about rewarding designers for innovating around sustainability, how does that work?

LV: As with any company centered on innovation, the process begins with Nike’s designers. To influence the designers to make responsible choices, Nike designers are scored against the Considered Index. In order to get new Considered innovations adopted faster, Nike gives innovation points to designers who come up with a brand new idea, as well as to teams who adopt considered innovations in the first year.

SS: And how are employees outside of the design department scored against the Considered Index?

LV: At Nike, there are so many different groups in different matrices, a lot of them are expected to calculate their CO2 footprint. But the Considered Index is primarily for designers.

SS: Sustainability 101 and Step by Natural Step (mentioned in this press release)- are they teaching personal sustainability practices, or teaching employees how to spot opportunities to be more responsible in the choices they make in their jobs?

100% Wind-Powered Island off Maine Financed Using Electricity Co-op

Susan Kraemer — Wed, 18 Nov 2009 04:13:12 +0000

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.
