Microgrids and Transformative Blockchain Potential - A CAES study of the Rutgers Grid

Blockchain technology’s fully reliable hierarchical ledger capabilities makes it a perfect candidate for alternative technology applications outside of its traditional cryptocurrency use. Here at CAES we are looking into specific use cases for blockchain. More specifically, if the Rutgers microgrid – which includes a roughly 28MW Busch Campus load, a 15MW Cogeneration Plant and 9MW of solar panels – were to act as an island-able, prosuming microgrid and sell excess generation. An economic opportunity cost-benefits analysis is being performed as well as how the promotion of renewable energy could increase the value of our green energy. A secondary focus is to calculate and derive the pedigree classification factors which include efficiency, emissions, loss of attributes, reliability and a few other factors of our Rutgers CHP plant. We are hopeful in finding relations that can give us a new pricing model for excess energy to be sold to other plants or back to the grid.

SMART Manufacturing

SMART Manufacturing is an emerging field that uses sensors to connect industrial machinery within a manufacturing plant to the internet for the purposes of data analytics and remote status monitoring.  CAES is working to develop a process and protocol for identifying and recommending SMART projects to manufacturers within the Industrial Assessment Center Program, including questions to ask plant personnel, observations to make during the plant tour, and measurements to take throughout the day. Currently, CAES is studying the applications of the ABB Smart Sensor - a non-invasive instrument that relays the physical data of a traditional motor to the user via bluetooth technology. The sensor’s capacity for short-term data collection and the modeling potential of said data is being investigated. 

Industrial Demand Response Utilizing Lithium Ion BESS

Battery Energy Storage Systems (BESS) represent an enormous market and savings potential for industrial needs, particularly in demand response as greater energy production needs put greater strain on energy grids across the country, driving up demand pricing as high as $43/kW in some manufacturing municipalities in California. Lithium Ion technology is the current industry standard, but represents significant economic investment for small and medium sized manufacturing companies. Though battery cost is rapidly dropping, companies still hold methodology and pricing close to the vest. CAES is conducting research into the technology, sizing, price-points, and case-identification for commercial demand response solutions of Lithium Ion BESS.

Design Optimization for Wave Energy Conversion Co-Located with Offshore Wind Farms

Hydropower is a relatively old technology, but Wave Energy Converters (WECs) are an emerging industry, experiencing rapid expansion in the last 5 years and are currently positioned where wind was about 8 years ago. In the field of marine energy capture, they represent a safer, simpler, and more economic alternative to tidal and offshore wind energy. While wind farms are a more mature technology and industry than current WECs, energy provided by ocean waves is denser, more consistent, and more predictable than wind, holding greater earning potential. Furthermore, WECs provide significant ancillary benefits to nearby marine structures, especially wind farms. CAES is conducting research into the optimization of Wave Farm designs co-located and sharing infrastructure with offshore wind to produce the greatest economic yields from power generation per square foot as well as stimulate further development in the Wave and Wind Farm industries.

Past Research

Novel Applications of Fluidized Beds

Fluidized beds have enormous potential to improve environmental performance of coal combustion. At CAES, we have studied a wide range of topics related to fluidized bed performance optimization including minimization of temperature fluctuations and the effects of vibration on the system. In addition, we primarily focused on mixing in fluidized beds and breaking up large agglomerates. Designing the size and shape of these objects requires accurate modelling of drag and buoyancy effects, and development of an understanding of the “unfluidized hood” which appears on top of any large submerged object. 

Dropwise Condensation Modification by Surface Functionalization and Droplet Removal

Through functionalization of a thermally conductive, hydrophilic solid substrate's surface, by dual micro and nano scale roughening and reduction of surface energy to induce superhydrophobicity, the rate of condensate production and heat transfer is modified for dropwise condensation on the cooled surface, when condensate is continuously removed from the condensing surface.

Application of Vortex Tubes in Waste Pressure Energy Recovery

Vortex tubes are devices that separate an incoming flow into two output streams: one that is higher temperature than the input, and one that is lower temperature than the input. Traditionally, vortex tubes operate at high pressure, and the cold output is used to cool various devices. At CAES, we have explored the innovative possibility of using vortex tubes to recover waste pressure energy created in industrial processes. In the past we have focused on cases of energy recovery where phase change occurs in the vortex tube.
