Italian Firm Wins Contract to Build Massive African Hydropower Plant. Italian construction firm Salini Costruttori said on March 31 it has signed a €3.35 billion contract with Ethiopia state-owned Ethiopia Electric Power Corp. to build a 5,250-MW hydropower plant on the Blue Nile, a tributary of the Nile River. The project, slated to be completed […]

The Russian Investigative Committee has completed a probe into the August 2009 accident at the Sayano-Shushenskaya Hydro Power Plant in Siberia that killed 75 people. The committee has charged seven people—including the plant’s former head, Nikolai Nevolko, his deputies, and the plant’s former chief engineer, Andrei Mitrofanov—for violating safety rules. If found guilty, the officials could face five years in jail.

In April, Japan’s Nuclear and Industrial Safety Agency provisionally raised the accident rating for three reactors at the crippled six-unit Daiichi nuclear plant in Fukushima Prefecture to Level 7—making it a “major accident” and putting it on par with the 1986 Chernobyl accident in the Ukraine. Recovery efforts continue at the nuclear plant with workers […]

Weeks after a massive magnitude 9.0 earthquake and subsequent 14-meter-high tsunami devastated Fukushima Prefecture in northeastern Japan, workers from the Tokyo Electric Power Co. (TEPCO) were still struggling to regain control of four severely damaged reactors at the six-unit Fukushima Daiichi nuclear power plant.

The People’s Republic of China’s Congress approved a much-anticipated draft of the country’s 12th Five-Year Plan (2011–2015) on March 14. Along with key objectives that included boosting its gross domestic product (GDP) by 7% annually on average, the country for the first time in a five-year plan established targets to tackle climate change. It plans to reduce carbon dioxide emissions per unit of GDP by 17% from 2010 levels by 2015 and to reduce energy consumption per unit of GDP by 16% from 2010 levels by 2015.

Subsidized by the Dutch government, a number of Dutch utilities, the European Membrane Institute at the University of Twente, and Dutch consulting firm KEMA have, for over a decade, been testing membrane technology that promises to directly convert water vapor from power and other industrial plants’ flue gases into drinking water. The technology could provide a new source of large volumes of potable water.

Competition among offshore wind turbine vendors vying for market share went into overdrive in the first three months of 2011 as several key players announced gigantic new turbine models.

A major technical advance in hydroelectric dam safety was achieved this March as Alstom’s Chinese arm, the Tianjin Alstom Hydro Co. (TAH), delivered what it called “the world’s first self-closing electronic ring gate control system” to the Ahai hydropower project in China.

Researchers at Sandia National Laboratories say a project that focuses on supercritical carbon dioxide (CO₂) Brayton cycle turbines is moving to the demonstration stage.

Like most forms of generation, solar power has its disadvantages. Two cited most by critics of photovoltaic (PV) or concentrating solar power facilities are that they require large expanses of land and that solar cell fabrication and maintenance costs are high. Several companies have been assessing a new approach to tackling these factors: installing solar plants on water.
