New System Converts Cow Manure into Clean Water

By combining an anaerobic digester with a filtration and reverse osmosis system, an idea developed at Michigan State University evolved into a system that turns cow manure into clean water, while also capturing nutrients that can be reused as fertilizer. The development, which has been about 10 years in the making, is called the McLanahan Nutrient Separation System. It is said to be able to produce 50 gallons of clean water from 100 gallons of manure. MSU is hoping that the technology can be commercialized by the end of the year.

Investment Void Seen to Affect Europe’s Power Supply

Europe is at risk of running short of power because wholesale electricity prices are too bleak to encourage spending on new thermal plants, says the International Energy Agency. The Paris-based agency notes that Europe needs more than $2 trillion in power industry investments by 2035 and about 100 gigawatts of new thermal capacity until 2025. Electricity rates are more than 20 percent below the level necessary to spur investment, adds the IEA.

EU Asks for Deeper U.S. Emissions Cuts to Protect Climate

The European Union said that the U.S. must do more to curb greenhouse gas emissions than the recently released proposal recently announced in Washington.  The decision calls on existing power plants to reduce fossil fuel pollution by 30 percent from 2005 levels by 2030.  The European Commission, the EU’s regulatory arm, has proposed to its 28 member nations to cut green house gases 40 percent by 2030, doubling the scale of reduction it is making by 2020. Without action, scientists say the planet will warm more than 2 degrees, the steepest since the last ice age. Environmental groups agree with the EU that the U.S. and other nations must o more to fight the risk to the climate.

Abengoa $600 Million Spinoff Shows Momentum for Yieldcos

Abengoa SA is beginning the initial public offering of its renewable energy unit,  in a spinoff that is being imitated by other companies such as SunEdison Inc. The Spanish energy company’s Abengoa Yield Plc unit is expected to sell 23.1 million shares at around $25 to $27 per share to generate gross proceeds of $600 million at the mid-price. It is one of a half-dozen companies known as “Yieldcos” that energy providers have said they were considering this year to separate units that develop new power projects from those that operate completed assts and enjoy a lower cost of capital.
