Vandium Redox Flow Battery - From Imergy Power Systems

This magic box is called a vanadium redox flow battery. The heart of a flow battery are two electrolyte solutions — one positive, one negative — contained in separate tanks. When the solutions are pumped through a power cell containing a membrane, a chemical reaction takes place that generates electricity. When the process is reversed, the electrolyte stores energy.
The key component is vanadium, a naturally occurring element that can exist in positive and negative states, eliminating the contamination and degradation that occurs when two different elements are used to create a chemical reaction. Flow batteries are not as efficient as solid-state lithium-ion batteries. But unlike lithium-ion batteries that lose their capacity over time as they charge and discharge, the nontoxic electrolyte in a vanadium flow battery is endlessly reusable and never loses its efficiency.
Vanadium flow batteries are not new — an Australian scientist named Maria Skyllas-Kazacos invented the technology in 1985. But there was a catch. Two, actually. The battery needed pure and pricey vanadium to work. And the fact that the electrolyte became unstable at 35 degrees Celsius (95 degrees Fahrenheit) limited the usefulness of the batteries.
“The electrolyte was always the one cost you couldn’t squeeze because you needed pure vanadium,” says Tim Hennessy, Imergy’s president, who previously ran a Vanadium battery company in China. “So the batteries ended up being about 50 percent more expensive.”
But Imergy claims it has made a big breakthrough. First, chief technology officer Majid Keshavarz developed a novel electrolyte chemistry that allows Imergy to use a lower grade of vanadium that can be extracted from iron ore waste, oil sludge, or fly ash generated by coal-powered power plants.
Their 30 KW battery will be housed in a 40' shipping container and cost >$15,000, should be in production by 2017.

The Hidden Costs of Carbon Fuels

The problem with MCHM (4-Methylcyclohexanemethanol), a coal-washing chemical created by humans, is that you can not filter it out of the water. Thanks to "Freedom Industries".

From Here and Now:

It’s been called one of the most serious episodes of drinking water contamination in U.S. history. Four months after thousands of gallons of the coal-washing chemical MCHM spilled from an unregulated above-ground storage tank into the Elk River, many people in and around Charleston, West Virginia, are still using bottled water.
Water bans after the Jan. 9 spill lasted as long as nine days in some Charleston communities. But residents continue to report that the water smells like licorice and it has sent people to the emergency room. A recent article in The New Yorker that profiled the power of the coal industry in West Virginia called the spill an accident with no clear ending, with the most basic question — “Is the water safe?” — unanswered.
Dr. Rahul Gupta, who runs the Kanawha-Charleston and Putnam County health departments in Charleston, West Virginia, speaks with Here & Now’s Meghna Chakrabarti about the ongoing water crisis.

Nowhere To Hide From Global Forest Watch

Nowhere To Hide From Global Forest Watch

SustainableBusiness.com News
There's nowhere to hide now that Global Forest Watch has launched - citizens around the world now have all the information they need to monitor the state of the world's forests.

Global Forest Watch combines the latest satellite technology, open data and social media crowdsourcing to produce "near-real time, reliable, and actionable data" about what's happening to forests worldwide.
High resolution data from half a billion NASA Landsat satellite images measures whether tree cover is growing or lessening. You can even sign up for alerts that let you know when there's tree cover loss, pinpointing where it's occurring.
"Businesses, governments and communities desperately want better information about forests. Now, they have it," says Andrew Steer, CEO of World Resources Institute, which facilitated the project. Global Forest Watch "will fundamentally change the way people and businesses manage forests. From now on, the bad guys cannot hide and the good guys will be recognized for their stewardship."
Companies that buy commodities such as palm oil, soy and timber will be able to see for themselves whether suppliers are complying with laws and sustainability standards. When they do it right, suppliers will be able to conclusively show their products come from well-managed forests. No more wondering about who is telling the truth!

And forest protection groups can use the information to pressure companies and governments to stop deforestation.
Forests - Global Forest Watch
Until now, the usefulness of satellite images has been limited because of the long time lag in getting them online. By the time people see them, the forests are cut, cattles are grazing (or palm trees are growing) and criminals are long gone. It typically takes 3-5 years to produce a national forest cover map.
"With the exception of Brazil, none of the tropical forest countries have been able to report the state of their forests," says Rebecca Moore, engineering manager with Google Earth Outreach and Earth Engine. "Now it will be possible to have near real-time updates of the state of the world's forests, open to anyone to use."

It's also a great tool for corporations that have committed to purchase only from sustainably managed forests. Nestle, for example, says the tool will give it better oversight of suppliers that produce raw materials such as meat, soy and palm oil - which forests are often cleared to grow.
"It is going to help us dramatically to refine our work on the ground, in places where we think there might be issues with our supply chain," says Duncan Pollard, associate vice president for sustainability at Nestle. 
Global Forest Watch makes this possible by embedding key information in the images. You can see which palm oil company operates in a specific area of Indonesia where images have shown recent forest destruction. That could lead to a buyer canceling purchases from a supplier.

So if a palm oil company says it will no longer clear primary forests, now they will be watched to make sure they keep that promise.

The REDD market should also get a boost. When organizations buy credits for maintaining or restoring forests, and can actively view their progress, they will be more likely to invest.

It will also give people a birds-eye view of the extent of deforestation across the world.

The initial $25 million to build the tool came mostly from the governments of the US, UK and Norway. It's been developed by a partnership convened by the World Resources Institute, which includes Google and some 40 partners - the UN Environment Program (UNEP) and businesses and NGOs from around the world.

Sarawak Geoportal Launches
Another tool, Sarawak Geoportal, focuses specifically on the Malaysian state, Sarawak, which has been torn apart by  deforestation.
The government can no longer misrepresent what's happening on the ground as they have done for political reasons, say The Bruno Manser Fund, which developed and launched the tool.

The online map makes it clear where concessions have been granted for logging and palm oil plantations and shows deforestation. It also pinpoints the exact location of villages, roads and rivers. 

It's necessary, says the Bruno Fund, because the government rarely informs indigenous people about projects that involve their native lands. Believe it or not, communities weren't aware that they would have to move because of construction of the very controversial Murum dam until right before they were forced to leave. 

"All this information should have been made public by the Sarawak government long ago", says Lukas Straumann, director of the Fund. "The data have deliberately been shut away to facilitate the land grab by the political elite under outgoing Chief Minister Taib Mahmud."

Sarawak Geoportal shows that as of 2009, a maximum of
11% of land area remains covered by primeval forest.

Stanford scientist unveils 50-state plan to transform U.S. to renewable energy

Pick a state: The Solution Project - California

Mark Jacobson and his colleagues have created a 50-state roadmap for replacing coal, oil and natural gas with wind, water and solar energy.

This interactive graphic shows how each state can move to 100 percent renewable energy by 2050. Seehttp://thesolutionsproject.org/infographic/.
Stanford University scientist Mark Jacobson has developed a 50-state roadmap for transforming the United States from dependence on fossil fuels to 100 percent renewable energy by 2050. He unveiled the plan at the annual meeting of the American Association for the Advancement of Science in Chicago.
"Drastic problems require drastic and immediate solutions," said Jacobson, a professor of civil and environmental engineering. "Our new roadmap is designed to provide each state a first step toward a renewable future."
The motivation for the 50-state plan, he said, is to address the negative impacts on climate and human health from widespread use of coal, oil and natural gas. Replacing these fossil fuels with clean technologies would significantly reduce carbon dioxide emissions that contribute to global warming and spare the lives of an estimated 59,000 Americans who die from exposure to air pollution annually, he said.
In recent years, Jacobson and his colleagues have developed detailed proposals for converting the energy infrastructures of New York, California and Washington states to 100 percent wind, water and solar power by 2050. The new plan includes an online interactive map tailored to maximize the renewable resource potential of each of the 50 states. Hovering a cursor over California, for example, reveals that the Golden State can meet virtually all of its power demands (transportation, electricity, heating, etc.) in 2050 by switching to a clean technology portfolio that is 55 percent solar, 35 percent wind (on- and offshore), 5 percent geothermal and 4 percent hydroelectric. Nuclear power, ethanol and other biofuels are not included in the proposed energy mix for any of the states.
"The new map provides all of the basic information, such as how many wind turbines and solar panels would be needed to power each state, how much land area would be required, what would be the cost and cost savings, how many jobs would be created, and how much pollution-related mortality and global-warming emissions would be avoided," Jacobson said.
The 50-state plan is posted on the website of The Solutions Project, a nonprofit outreach effort led by Jacobson, actor Mark Ruffalo (co-star of The Avengers), film director Josh Fox and others to raise public awareness about switching to clean energy produced by wind, water and sunlight. To publicize the plan, Ruffalo joined Solutions Project member Leilani Münter, a professional racecar driver, at a Feb. 15 Daytona National Speedway racing event that Munter participated in.
"Global warming, air pollution and energy insecurity are three of the most significant problems facing the world today," said Jacobson, a senior fellow at the Stanford Woods Institute for the Environment and the Precourt Institute for Energy.
"Unfortunately, scientific results are often glossed over. The Solutions Project was born with the vision of combining science with business, policy and public outreach through social media and cultural leaders – often artists and entertainers who can get the information out – to study and simultaneously address these global challenges."
Mark Shwartz writes about energy research for the Precourt Institute for Energy at Stanford University.
