South Fork of Long Island (SFLI) is a high-density residential area facing power shortage in coming years. Due to large summer population, the electricity demand has a distinct seasonal pattern. The annual average power demand is 55 MW, however the summer month demand is 95 MW on average, reaching values as high as 140 MW for 10-20 hrs. In this project CIEES-UTS team is evaluating liquid salt (ZEBRA) batteries as an energy storage solution for South Fork region. ZEBRA batteries offer a low-cost energy storage that is better suited for an area with distinct seasonal energy demand. The battery normally operates at 300oC, when cooled to the ambient temperature it can be stored indefinitely. A battery farm would be activated for summer month only, thus requiring no off-season maintenance.

CIEES Completed Projects
The Center for Integrated Electric Energy Systems has engaged in a variety of energy projects with our industrial partners, including National Grid, Con Edison, Unique Technical Services LLC, ChemCubed LLC, and more.
View our completed projects below.
Principal Investigator: Dr. Fang Luo
Industrial Partner: JetCool LLC
The project develops microconvective liquid cooling technology that uses arrays of fluid jets to cool the industry's highest power devices. Unlike typical heat sinks or cold plates that pass fluid over a surface, our cooling jets route fluid directly at the surface, creating an order-of-magnitude improvement in heat transfer. CIEES assisted the SBU team in setting up the experiment in the Advanced Energy Center.
Principal Investigator: Dr. Fang Luo
Industrial Partner: PowderMet Inc
These projects develop high resistance, high permeability and saturation, low coercivity magnetic cores for power conversion systems. The developed soft magnetic will benefit the current state-of-art of soft magnetic to allow designers to increase system power at high frequency while reducing the weight and size, also reducing (or, in some cases, even eliminating) the need for costly, large, and heavy cooling systems. The CIEES team assisted in calorimetric measurements of the magnetic alloys.

Industrial Partner: Consolidated Edison Company
Hydrogen storage units in Prof. Mahajan's labThe project studies the Hydrogen absorption/desorption kinetics in mixed metal hydrides on the Power to Gas unit. It is known that hydrogen storage in metal hydrides is one of the attractive approaches for storing gaseous hydrogen. One attractive class of metal hydride system, mixed metal alloys, shows high hydrogen storage capacity, rapid kinetics and a relatively long electrochemical charge-discharge cycle life. The excellent properties of alloy type hydrides alloys makes them promising for stationary hydrogen storage. CIIES team assisted IGIT in assembly and provided gas analysis equipment.

Industial Partner: National Grid
National Grid is one of the largest investor-owned energy companies in the world - covering Massachusetts, New York, Rhode Island and the UK. The company is delivering clean energy to support our world long into the future.
The CIEES team is evaluating market and technology for distributed energy generation using gas on Long Island. The goal is to estimate impact of renewable gas on Power Production on Long Island. Distributed natural gas generation is considered a viable option for relieving grid strain in congested load pockets, such as South and North Forks of Long Island. The natural gas generators, working in tandem with renewable energy sources, offer an economic alternative to chemical energy storage in some load pockets.
The CIEES team, led by Prof. Dr. Devinder Mahajan, Director of Institute of Gas Innovation and Technology (I-GIT), identified hybrid gas sources based off-grid technologies for distributed power production. Specifically, 20kW skid-mounted systems are the optimum solution for distributed power generation
