New Component Manufacturing Furthers Efficiency Improvement for Siemens Gas Turbines

ERLANGEN, Germany–()–Siemens Energy has recently opened a facility in Charlottesville, Virginia for the innovative commercial production of airfoil ceramic cores for gas turbine blades and vanes using the TOMOSM technology, initially developed by Mikro Systems, Inc. The advancements are expected to improve the cooling capability of gas turbine blading, thus enabling higher levels of engine performance and efficiency for future Siemens Gas Turbines. This technology is available to Siemens as a part of the Technology License agreement with Mikro Systems.

With support from the U.S. Department of Energy (DOE) and the American Recovery and Reinvestment Act (ARRA), Mikro Systems was funded via Small Business Innovation Research (SBIR) grants. Mikro Systems and Siemens Energy partnered to develop the application of its patented Tomo-Lithographic Molding (TOMOSM) manufacturing technology to a range of gas turbine components.

GE’s Innovative Natural Gas Turbines See Global Popularity

general-electricThe world’s largest collection of medical research institutions and hospitals, the Texas Medical Center, depends on GE’s natural gas-fueled turbine unit to support its 280-building empire. That same technology was used to provide Japan with power after the devastating earthquake and tsunami in 2011, and will be used to power next year’s Winter Olympic Games in Russia.

Despite public concern over the industry’s methods of tapping more natural gas reserves, via “fracking,” the source remains an important, inexpensive and cleaner fuel compared to its fossil fuel counterparts.

GE’s unit that has supported the medical center since 2010 represents a type of system that has become increasingly popular around the world, playing up its reliability to deliver regular and backup power during outages or shortages. There are over 2,200 active turbines in 76 countries around the world, including remote areas in the Amazon.

Each turbine takes about ten minutes to turn on, can be shipped and set up within a matter of weeks and provides fast and lasting power to areas stricken with natural disasters. The units in the company’s aeroderivative line have seen four years of double-digit growth in orders, with volume expected to increase another 25 percent this year.

Great River Energy Power Output Climbs as Emissions Drop

MAPLE GROVE, Minn.–()–Over the last seven years, Great River Energy has invested about $300 million to reduce emissions and increase electricity production at its power plants in Minnesota and North Dakota. From 2006 through 2012, Great River Energy increased electricity production by 4 percent, culminating with an all-time record of 11.13 million megawatt hours generated in 2012.

At the same time, Great River Energy significantly increased its purchase of renewable energy, including wind and hydropower. As a result of these purchases and power plant emission reductions, Great River Energy’s emission intensity has dropped significantly. Overall, sulfur dioxide emissions are down by approximately 50 percent; nitrogen oxides, 40 percent; carbon dioxide, 20 percent, and mercury, 10 percent.* Continue reading

REC Solar Slashes Energy Costs for Two California Farms

solar_wallpaperSAN LUIS OBISPO, Calif.–()–REC Solar, a leader in solar system design and installation, today announced the completion of solar energy systems for two California farms totaling one megawatt of electricity. Peter Rabbit Farms in Coachella and Amaral Ranches in the Imperial Valley have joined the ranks of growers, cold storage and food processing facilities that are “harvesting the sun” to hedge against rising electricity costs and save money.

With the completion of these systems, Peter Rabbit Farms and Amaral Ranches align with more than 300 California farmers and ranchers now utilizing solar energy to reduce utility bills. Agriculture represents nearly 30% of California’s commercial solar capacity, according to PV Solar Report, and experts anticipate the sector will continue to gain strength. Continue reading

Total Capacity of U.S. Department of Defense Renewable Energy Installations Will Quadruple by 2025

dodThe U.S. Department of Defense (DOD) currently spends approximately $20 billion per year directly on energy, consuming 3.8 billion kilowatts hours (kWh) of electricity and 120 million barrels of oil per year.  The effort to reduce energy costs and reliance on fossil fuels – often purchased from countries hostile to U.S. interests – and increase energy security, particularly for forward operating bases (FOBs), is driving sweeping changes to DOD policies around energy.

In particular, the DOD has ambitious plans to increase its use of renewable energy.  According to a recent report from Pike Research, a part of Navigant’s Energy Practice, the total installed capacity of renewable energy sources for the U.S. military will grow from 80 megawatts (MW) in 2013 to more than 3,200 MW by 2025 – increasing more than four-fold in 12 years.
