CO2 Sequestration advances
July 27, 2013 07:47 AM - Roger Greenway, ENN
Sequestration of CO2 has been discussed as one way to reduce the impact of burning fossil fuels on climate change by removing CO2 from industrial and power generation emissions and storing it indefinitely underground. This technology has been demonstrated in the laboratory and in pilot studies, but not in large scale tests. That is now changing. An injection of carbon dioxide, or CO2, has begun at a site in southeastern Washington to test deep geologic storage. Battelle researchers based at Pacific Northwest National Laboratory are injecting 1,000 tons of CO2 one-half mile underground to see if the greenhouse gas can be stored safely and permanently in ancient basalt flows. Boise Inc. teamed with Battelle, which operates PNNL for the U.S. Department of Energy, and Praxair, Inc. to conduct the CO2 injection phase of the pilot project. Injection is occurring on Boise property in deep basalt — the same massive ancient lava flows that underlie major portions of Washington, Oregon and Idaho. The joint research is conducted under the Big Sky Carbon Sequestration Partnership, which is led by Montana State University and funded by DOE and a consortium of industrial partners. It is one of seven regional partnerships throughout the United States aimed at finding safe and economical ways to permanently store the nation's greenhouse gas emissions.
Tar-sands Infractions in Canada Get Swept Under the Rug
July 25, 2013 11:59 AM - Kevin Grandia, The Ecologist
A report released yesterday finds that enforcement of environmental infractions by companies in the Alberta oil sands are 17 times lower than similar infractions reported to the United State's Environmental Protection Agency (EPA) The report, authored by the environmental nonprofit Global Forest Watch, looked at more than 15 years of data on recorded environmental mishaps by oil sand's companies, tracking the follow-up actions taken and the final verdict on fines.
EV charging stations becoming more common
July 25, 2013 06:12 AM - MOVEFORWARD, Electric Forum
As the race to the mass market continues it seems as though the thoughts of electric vehicle drivers are now turning towards charging stations in their area. If you read the motoring press you will see much focus upon battery journey capacity when in reality there are now more charging stations than ever before, with recharging times now falling dramatically, a 30 minutes recharge while you shop could be all it takes to get you home. It will be interesting to see as and when the EV industry moves on to promote charging stations more aggressively to the wider public. Initially there were concerns about electric vehicle technology, this then switched to battery technology and while it would be wrong to say these two issues have been resolved conclusively there is no doubt that great progress has been made.
Electric Vehicles outpacing hybrids
July 23, 2013 04:36 PM - MOVEFORWARD, Electric Forum
The US Department of Energy has this week released a very interesting graph which shows the early-stage development of the hybrid market compared to the electric plug-in market. Many people have been of the opinion that hybrids offer an interesting steppingstone for the electric vehicle market but if sales forecasts are anything to go by the electric vehicle market is likely to outperform its hybrid counterpart. The graph took into account sales of electric vehicles and hybrids over the first three years of the technology. The start date for hybrids was 2000 and the start date for electric vehicles was 2011 — while some will point at an earlier Tesla Roadster Model made available before 2011 this was not designed for the main market.
Did Earthquake damage Iranian Nuclear Power Plant?
July 22, 2013 04:52 PM - Editor ENN, SciDevNet
Arab Gulf states have raised concerns about the safety of an Iranian nuclear power station built in an earthquake-prone coastal area. The concerns about the Bushehr plant, which officially opened in 2011, were raised during a meeting of the 35-nation board of governors of the International Atomic Energy Agency (IAEA) in Vienna, Austria, last month (3-7 June). The reactor lies on the north-east coast of the Arabian Gulf. Any leak of radioactive material could therefore affect coastal regions of Bahrain, Kuwait, Qatar, Saudi Arabia, the United Arab Emirates and Oman's Musandam Peninsula.
World Population Growing Fast & Unevenly
July 20, 2013 07:40 AM - Population Matters from International Business Times
It's no secret that the world's population growth is heavily skewed by region — so much so that the changes expected for the next century will radically change the world as we know it. But according to projections recently revised by the United Nations Population Program, those changes will come even faster than we thought. The UN has dispensed with the old estimate that Africa's population will triple within 90 years — instead, it could very well quadruple.
Volta River and Climate Change
July 19, 2013 11:44 AM - Editor ENN
A new study released today finds that so much water may be lost in the Volta River Basin due to climate change that planned hydroelectric projects to boost energy and food production may only tread water in keeping up with actual demand. Some 24 million people in Ghana, Burkina Faso and four other neighboring countries depend on the Volta River and its tributaries as their principal source of water. Specifically, the researchers with the International Water Management Institute (IWMI) and their partners concluded that the combined effects of higher temperatures and diminished rain could mean that by the year 2100, all of the current and planned hydroelectric projects in the basin would not even generate as much power as existing facilities do now. Meanwhile, there would only be enough water to meet about a third of irrigation demand.
Using the free market to fight climate change looks like a winner!
July 17, 2013 07:11 AM - ScienceDaily
The best way to reduce carbon emissions and combat climate change is through the use of market forces, according to a new study. Researchers who monitored the effectiveness of the European Climate Exchange (ECX) -- the world's biggest carbon trading platform -- found it to be as efficient as Europe's two biggest exchanges, the London Stock Exchange and the Euronext Paris. Using free market platforms like the ECX to combat climate change could provide the basis for the introduction of a mandatory emissions cap and trade scheme worldwide.
Sea level rise may be underestimated by models
July 16, 2013 07:25 AM - Roger Greenway, ENN
Think sea levels will rise only a bit in response to an increase in global temperature of one degree? Think again! A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms. This international study is one of the first to combine analyses of four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes. Results of the study, funded primarily by the National Science Foundation and the German Federal Ministry of Education and Research, are being published this week in the Proceedings of the National Academy of Sciences.
Study finds Loggerhead turtles depend on broader range of habitat than previously thought
July 15, 2013 04:51 PM - Editor, ENN
A new US Geological Survey study suggests that the threatened loggerhead sea turtle may require broader habitat protection during the nesting season. "This is the first study to locate and quantify in-water habitat use by female loggerheads in the Northern Gulf of Mexico subpopulation during their reproductive periods," said lead author Kristen Hart, a USGS research ecologist. "Our tracking results show they depend on a much broader range of habitat during this critical part of their lives than was previously thought to be required."
