Research Project Summary Information

Renewable Energy Aquaculture Facility(ST9661-1)

Town of Hempstead,


The Town of Hempstead has been growing shellfish (used to seed the bay) since the mid 1980s, with a maximum capacity of two million Hard Clams. The current process has limited space, high energy and operating costs, and rigorous maintenance requirements. The proposed project would increase energy efficiency, as well as quadrupling productivity and reducing labor-intensive maintenance requirements. The town will integrate renewable energy with a reconfigured floating upwelling system (FLUPSY) that will allow the entire operation to be self sustaining.

Project Description

The proposed project aims to quadruple shellfish production to eight million hard clams, using clean, renewable energy. The scope includes: •Install meters and procure material •Construct reconfigured and relocated FLUPSY offshore •Install fuel cell •Dredge bay •Construct pile, platform, and clam seed facility •Install, test, and calibrate solar and wind equipment •Analyze data •Tech transfer


The project offers economic benefits for the local community in that it is expected to improve the clamming industry by increasing productivity and capacity, and reducing maintenance and energy costs. In addition, Hard Clams are a critical species that maintain water quality. The increasing production of such species is important to the ecological health and equilibrium of the entire bay. The site is currently used as an educational tool for the community, so the energy benefit will be exposed to a broad population.

Project Results

The solar- and wind-powered shellfish nursery allows scientists to raise "seed" clams to deposit in local beds, enhancing the clamming industry and the ecological health of the bay. FLUPSY (Floating Upweller System) supports a shellfish grow-out process that provides a controlled environment that force-feeds nutrient-rich water to infant shellfish, allowing them to grow more quickly with a higher survival rate. The clean energy technology and the innovative design of the shellfish nursery have slashed energy costs at the facility, while increasing its ability to raise shellfish by 800%.
