purpose objectives integration
Purpose, Objectives, & Integration

DOE Program Objectives

To develop a hydropower generating micro-grid infrastructure for low head irrigation power and rural electrification along rivers, waterways, canals and streams using variable speed generators and low-cost turbines manufactured with plastic materials

Project Purpose

To meet the DOE objectives precisely with a revolutionary design and prototyping of turbine components using highly durable plastic and use of variable-speed generators with appropriate power conditioning electronics to provide reliable power supply that can be easily integrated into the electric grid

Relation to Program Objectives:

  • Develop low-cost environmentally friendly hydropower harvesting technology that integrates off-the-shelf power generating components, andcan be easily manufactured, assembled and deployed to harness the unused hydropower potential in natural and human developed waterways

Team

New Mexico State University

Project Partners & Contributors

Elephant Butte Irrigation District (EBID) and Tremont Electric Inc., will contribute significantly to the success of this project in terms of manufacturing, assembling and testing two 10 kW Scalable Low-head Axial-type Venturi-flow Energy Scavenger generating units.

EBID’s extensive network of gravity-fed canals provide wide range of low-head and low-flow rates serves as our ‘living laboratory’ to test and evaluate the proposed Scalable Low-head Axial-type Venturi-flow Energy Scavenger hydropower generators. Contributors are: Henry Magallanez, Fernando Cadena, Zack Libbin.

Tremont Electric Inc., has a distinguished track record in advanced energy technologies and will participate in suggesting/recommending fabricating and commercialization strategies of the Scalable Low-head Axial-type Venturi-flow Energy Scavengertechnology. Contributor is Aaron LeMieux.

Project Management

The Principal Investigator Ram Prasad has received a U.S. Fulbright Scholar award for teaching and researching hydropower harvesting in Vietnam for a period of 6 months beginning January 2012 through June 2012. Through a prior telecon with Erik Mauer, Hoyt Battey and Ed Eugeni it has been agreed that Ram Prasad will be in frequent contact with Satish Ranade (Co-PI) and graduate students via email and telephone towards successful conduct of work at New Mexico State University. Ram will be returning to fulltime normal duties as PI in July 2012.

The synergy between the DOE award and the vast amount of low-head hydropower available in Vietnam, especially in the Mekong River Delta, will allow better understanding of how efficient approaches to harvesting can bring about energy sustainability. Ram’s Fulbright experience will add considerably towards building better insights to harvesting the unexplored potential of low flow-rate hydropower resources. This is an important realization in fulfilling DOE’s WPP vision of meeting 30+ GW of hydropower generation by Year 2030 from low-head/low-flow waterways in the U.S.
