Compressed Air Systems: Low Hanging Fruit for Energy Savings

Carl Weinschenk

Compressed air is a staple of many industrial facilities. These systems tend to be “leaky,” and finding and fixing these sometimes tiny holes and gaps is a great way to save money. “It is low-hanging fruit in that most people with a compressed air distribution network in their plant have some amount of leakage,” said Bill Barnes,   …Continue Reading

Hybrid Gensets Can Help Solve a Big Problem for the Mining Industry

Carl Weinschenk

Solar-diesel hybrid gensets balance the solar output with the guaranteed output from the diesel element. THEnergy Consulting and Danvest have released a study suggesting that these hybrid platforms are perfectly suited to the mining industry. The study shows that low-load gensets almost double use of solar and enable the diesel elements to run far more   …Continue Reading

The Use of Renewables in Mining Operations

Carl Weinschenk

Mining operations consume a tremendous amount of energy. These firms, therefore, are interested in solar power. The attraction of solar is even greater due to the fact that mines often are far from the grid. A German company, Cronimet Mining Power Solutions, has built a solar-diesel hybrid power plant at the mega watt scale at   …Continue Reading

Steel Company Saves Energy with New Turbine Blowers

Linda Hardesty

ArcelorMittal Galati, a steel and mining company, has invested more than $7 million to upgrade a set of turbine blowers, aimed at reducing energy consumption at one of its blast furnaces. The turbine blowers inject cold air into the blast furnaces, and are key to the technological flow of the unit. Following the investment, the   …Continue Reading

In addition to electrical system design,   …Continue Reading

New Technology Saves Water, Generates Energy

Karen Henry

The University of Arizona (UA), in collaboration with RePower Design, has developed a new technology that slows the evaporation of water from mining tailings ponds and reservoirs, while simultaneously generating solar energy, reports Mining Innovation News. Called Hexocover, the technology consists of modular floating hexagonal plastic panels that can be linked together to cover over   …Continue Reading

5 Trends Disrupting the Global Energy Landscape

Matt Smith

At a time of high uncertainty in energy markets, a few trends and issues are changing the world and disrupting the global landscape. Geopolitical factors are influencing the oil and liquefied natural gas (LNG) markets. Many countries have introduced new carbon schemes to reduce emissions, while the European Union is overhauling its plan and Australia   …Continue Reading

Industrial-Scale Thermoelectric Generator Debuts

Linda Hardesty

Alphabet Energy introduced its E1 thermoelectric generator, which attaches to an exhaust stack to capture exhaust heat and convert it into electricity. The industrial-scale thermoelectric generator is the first product introduction for the company, which was founded in 2009 at Lawrence Berkeley National Laboratory. Thermoelectrics use a temperature differential to generate electricity in the solid   …Continue Reading

High-Intensity Blasting Improves Energy Efficiency

Karen Henry

Milling ore requires more electricity than any other part of the mining process, and Australian mining services company Orica has found a way to make the process more energy efficient, according to a Sourceable article. By raising the explosive energy by several times, mines are able to produce a much finer ore, which in turn   …Continue Reading
