Electric vehicles

Every 10,000 miles driven in an electric vehicle (EV) equates to the amount of power needed by one home in the USA for a year, said Donald Karner, President and CEO of electric vehicle (EV) vendor ECOtality North America, at this year’s PowerGen conference.

New engine modifications for greater output and efficiency

Industrial gas turbine performance by OEMs and the bold moves taken by GE and Westinghouse to produce larger units were discussed in the third part of this series. More innovative models and modifications were introduced by Brown Boveri and GE in the coming years, for greater efficiency.

Southern Research develops new methods to capture pollutants

Engineers and technicians at the Birmingham-based Southern Research Institute have come up with new methods to measure the levels of mercury, trace elements, hydrogen chloride, and fine particles being emitted from power plants. Robert Dahlin, director of Southern Research's Power Systems and Environmental Research in Alabama said many plants have already installed or are in the process of installing scrubbers that can be optimized for capturing certain pollutants.

Art Titus is Elliott Group's COO

Elliott Group recently announced that Art Titus has been named Chief Operating Officer, succeeding outgoing COO Tony Casillo, who retired in December after 36 years with Elliott. Over the past six years, Tony Casillo led Elliott through a period of sustained growth and the closer integration of our global operations, said Yasuyuki Uruma, CEO of Elliott Group.

Invention of early jet engines and industrial gas turbines

The Rankine Cycle described in the second part of this series is working hand in glove with the gas turbine Brayton Cycle and has given us remarkable energy savings. With an improved part load heat rate, 65% combined cycle efficiency is targeted by 2016, which does not seem to be a distant dream.

The Brayton Cycle 

GE technology to drive South Korea's first IGCC plant

Korea Western Power Co. (KOWEPO) has selected GE technology for its first integrated gasification combined-cycle (IGCC) power plant to be built in South Korea. The 300-megawatt "cleaner coal" facility, one of the first in Asia, will help the South Korean government meet its low carbon emissions targets, while bolstering the country's electricity supply.

BP acquires 750KW MT250s

FlexEnergy Inc. has shipped three of its Flex Turbine MT250s to BP, to help the energy group further reduce its carbon footprint at its Wamsutter, WY, water disposal facility, through a contract with Power Service Inc. The 750KW system will utilize pipeline natural gas to produce continuous power in a grid isolated environment, while exceeding the highest air quality standards and powering on-site loads.

Thermodynamic cycles and modern machines

The Carnot Cycle we saw in the first part of this series is idealistic and efficient, but is not easy to use given today’s machinery. All other thermodynamic power cycles use the Carnot cycle as a guide to achieve maximum efficiency. In this second part of the series, the author throws light on the Otto, Diesel and Rankine cycles and their efficiency. The application of these cycles in modern-day machines is also discussed.

South Asia identifies 16,000 MW microhydro power potential

Energy sector professionals from the South Asian countries have estimated a rich potential of approximately 16,000 MW of microhydro power in India, Nepal, Pakistan and Sri Lanka. While India has identified 15,384 MW in small hydro potential, Nepal is looking at an additional 13,000 KW microhydro capacity by 2013. This is attainable with the implementation of certain policies in the construction and operation of microhydro facilities that are capable of achieving additional targets of about 300 MW micro and small hydro power every year.

Rolls-Royce wins Malaysian order

Rolls-Royce has recently won an order for gas turbine and compression equipment for the Tapis oil and gas field, offshore Malaysia. The equipment will be utilized by ExxonMobil Exploration and Production Malaysia (EMEPMI) to expand and extend the production of the field. 

The order includes two Rolls-Royce RB211-GT61 gas turbines, each driving twin Rolls-Royce RCB and RBB multi-stage barrel gas compressors. Each gas turbine compressor set will produce 27MW of power, which can deliver up to 390 million standard cubic feet of natural gas per day.
