GTI Team Selected by U.S. Department of Energy to Lead an $80M Supercritical CO2 Pilot Power Plant Project

Gas Technology Institute (GTI), together with partners Southwest Research Institute (SwRI) and GE Global Research, has been selected by the U.S. Department of Energys (DOE) National Energy Technology Laboratory (NETL) for an $80 million award to design, build, and operate a 10 MWe (megawatts electrical) sCO2 pilot power plant. The goal of this project is to advance the technology development of supercritical carbon dioxide (sCO2) Brayton power cycles.

Gas Technology Institute (GTI), together with partners Southwest Research Institute (SwRI) and GE Global Research, has been selected by the U.S. Department of Energys (DOE) National Energy Technology Laboratory (NETL) for an $80 million award to design, build, and operate a 10 MWe (megawatts electrical) sCO2 pilot power plant. The goal of this project is to advance the technology development of supercritical carbon dioxide (sCO2) Brayton power cycles.

In Brayton power cycles, high-power-density turbomachinery utilizes supercritical carbon dioxide (sCO2) as the working fluid. Historically, Brayton power cycles have only been used in spacecraft applications where compact, lightweight, high-energy-density power conversion is required, but these advantages are now being applied to terrestrial power generation for the step-change increase in efficiency and corresponding reduction in emissions they offer.
GTI will design, construct, commission, and operate a versatile 10 MWe sCO2 pilot-plant test facility located at SwRIs San Antonio, Texas campus. The project will operate at a turbine inlet temperature of at least 700oC aimed at advancing the state-of-the-art high-temperature sCO2 power cycle performance from proof-of-concept to a validated prototype operational system.
The project will address the research and development needs of the component vendors and support the risk reduction and commercialization needs of the systems integrators and end users. Developing and maturing the technology at pilot scale will spur the development of necessary equipment, understanding, and characterization needed for larger-scale sCO2 power conversion systems.
"GTI is excited that our team was selected by DOE-NETL to advance this critical new technology for clean power generation," says Eddie Johnston, senior vice president of research and technology development at GTI. "We will bring all the essential elements together to dramatically improve the efficiency of power plants and reduce greenhouse gas emissions."
Over the last decade, GTI project staff (formerly with Aerojet Rocketdyne) established a leadership position in sCO2 technology with work in cycle modeling and optimization, economic evaluations, advanced materials characterization, and design studies of key components (such as turbines, compressors, and recuperators.) In early 2016, GTI completed conceptual plans to support the design, cost, and schedule for the 10 MWe sCO2 Brayton Cycle test facility with funding from U.S. DOEs Office of Nuclear Energy (NE), in cooperation with the Office of Fossil Energy (FE) and the Office of Energy Efficiency and Renewable Energy (EERE).
"Our re-energized technology group is tapping the extensive energy and aerospace experience of the team to lower energy costs and provide cleaner sources of fuel and power," says Don Stevenson, executive director of GTIs new Advanced Energy Systems office in California.
Beyond this project, GTI researchers are working on a portfolio of technologies that can reduce the cost and environmental impact of electrical power plants. These include novel uses of captured CO2, advanced power cycles using supercritical CO2 rather than steam, low-cost oxygen generation (for oxy-combustion), and more efficient CO2 capture methods for plants without oxy-combustion.

SolarEdge Technologies - EV Charging Single Phase Inverter

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
