Renewable Energy Microgrid Overland Transportation Array
What is REMOTA™ ?
REMOTA™ is a portable microgrid (a power trailer) that generates renewable electricity and transports it to where it is needed. Electric power is produced by a patented axle-generation process that harvests mechanical energy as the axles turn and converts this energy to electric power via on-board generators. The electricity is stored in a bank of on-board batteries and is available for use in either DC or AC (120/240V).
REMOTA™ microgrid trailers are available in a number of power capacity configurations.
How does the REMOTA™ microgrid help improve sustainability and logistics?
Many large utility customers, including military installations, hospital campuses and universities, are considering microgrids to better manage energy usage and enhance power quality and system reliability. In addition to greater “energy security,” microgrids offer a variety of economic benefits ranging from greater efficiency of operation to the ability to facilitate participation in demand response and interruptible rate programs provided by the local utility.
While the use of distributed generation, backup power for critical loads, and the ability to self‐generate power in an island disconnected from the grid is not new, the term “microgrid” is gaining popularity and focus of government and commercial power users. Microgrids can take many forms, but for the purposes of this white paper a microgrid includes integration and control of multiple local generation and storage assets (diesel generators, combustion turbines, PV arrays, battery systems, etc.) to provide on‐site generation for local loads in both grid‐tied and islanded modes of operation. This follows the current DOE definition of a microgrid.
The U.S. Department of Energy’s official definition of a microgrid is “a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid (and can) connect and disconnect from the grid to enable it to operate in both grid‐connected or island‐mode.”
Over the past few years, there have been a number of other high profile natural disasters that have crippled the power infrastructure. Natural disasters such as Hurricane Katrina resulted in over 1.7 Million people losing their power, some for several weeks. Other catastrophes include severe weather outbreaks such as the tornadoes that crippled the Southeastern U.S. in April, 2011, and more recently, the EF5 tornado that devastated central Oklahoma. These storms all resulted in significant power disruption and loss of life.
Maintaining the power grid is not an easy job. Substation maintenance, system repairs and operations during normal and severe weather put forth challenges for the infrastructure that goes beyond just power loss. For instance, when power is lost over a widespread area due to tornadoes or other natural disasters, failure to perform repairs in a timely manner can result in loss of non-contaminated drinking water, food spoilage, elimination of heat/air conditioning (especially for critical areas such as assisted living, schools, etc.) and inability for service stations to pump gas for rescue effort vehicles that may need to operate on 24 hour shifts. Having mobile power and energy is a key asset to ensuring smooth utility operation and recovery.
REMOTA™ Trailers are Unique
The REMOTA™ platform utilizes a patented axle-mounted energy harvesting generator (U.S. Patent 7514803) and renewable integration capability to improve the fuel efficiency of equipment, vehicles, and long term operations. It utilizes modular energy storage, or “power blocks”, that can be connected to the power infrastructure of a mobile trailer/vehicle. When used for load-leveling generators, fuel reductions in excess of 40% are possible. This is possible when incorporated with existing diesel generators, renewable generation and grids.
In addition to enabling less fuel consumption, the energy storage will also enable uninterruptable, secure backup power, provide power and energy where it currently does not exist (especially during natural disasters), improve power quality and manage intermittent renewable energy sources when operating for extended periods in remote areas. By using a plug and play modular approach, various amounts of energy storage can be integrated within the REMOTA™ trailer to accommodate a number of different power and energy needs. This assures that the right amount of power and energy are available for each unique situation. Plus, plug and play capability with standard generators and grid assures ease of integration with existing systems.
The REMOTA™ trailer technology can be applied to various systems that support utility maintenance and recovery operations. It can be integrated into trailered gensets, lighting systems, and trailers for utility vehicles so that charging can occur while in-transit. When integrated with renewable systems, extended recovery operations can be realized and recovery can be accelerated due to this added capability.
When connected to a recovery vehicle the REMOTA™ on-board smart controller also allows the axle-mounted generator to provide torque-assist (for better fuel economy of the towing vehicle or to assist trailer recovery if it gets stuck). It also provides a charging source capability for the on-board energy storage while the vehicle/trailer pair is on the move. The REMOTA™ array can significantly improve fuel economy of the towing vehicle by utilizing the on-board energy storage to provide motive power. Upon completion of the mission, the renewable systems can be deployed to recharge the battery systems, potentially demonstrating a significant fuel economy increase to the vehicle with a near net-zero energy use.
REMOTA™ PROJECT OVERVIEW and ADVANTAGES over CURRENT TECHNOLOGY
Over a 24 month period, the REMOTA™ project seeks to validate a comprehensive mobile energy storage, generation, and management solution representing a significant advancement over the current state of the art. Innovations such as new, high density energy storage solutions will be tested to maximize energy, life, power and safety. Battery pack innovations, such as air cooling of prismatic cells, rapid charging of prismatic modules, high and low temperature use and extended life at longer ranges will be leveraged to optimize the mobile energy solution and represent distinct advantages for use in extreme or remote locations, in particular.
A novel, patented, mobile axle-generation system that provides advanced energy harvesting via a dynamic charging enhancement to the REMOTA™ mobile energy storage system will be constructed and demonstrated. Specific end user evaluation and input is a key element of this program. REMOTA™ is a significant advancement over existing mobile power platforms that do not possess this key energy harvesting feature. This will further enhance the benefits of this solution a result of increased mobile platform efficiency and recharging ability.
Novel software and hardware technologies will provide a real time dynamic assessment of distributed energy storage system efficiencies far in excess of conventional methods that are often hindered by OEM-driven limitations. Current OEM solutions are only vertically integrated with their own proprietary platforms and do not offer energy management visibility across other platforms which can seriously limit their performance and value.
The REMOTA™ project consists of the REMOTA™ mobile energy platform with e-Mobility Decisionware as a fully integrated solution:
1. REMOTA™ - Designed specifically as a mobile “energy expansion” platform configured initially to produce a minimum of 10 – 30 kilowatt hours (kWh), using advanced battery, fuel cell and generation technologies to enable expanded and stable energy distribution and to increase overall energy efficiencies.
2. e-Mobility Decisionware - Real-time, interrogative and dynamic software and hardware technologies for the management of distributed energy linking any and all fleet and energy management systems for decision intelligence with energy safety and performance monitoring which includes an advanced agnostic, multiple-chemistry battery management technology.
3. Integrated Solution - Provides a unique combination of breakthrough technologies for superior on-line, real-time, interrogative and/or remote management of disparate energy storage devices and systems that can be effectively deployed to directly connect to the grid for enhanced grid power management or to hybridize generators reducing costly fuel usage or to independently recharge electric equipment or vehicles where grid power is not otherwise available.
Innovative elements of this project include axle-generated electricity, advanced battery technology, battery sensing, analysis, on-line remote control, predictive and artificial intelligence algorithms and telematics technology.

REMOTA™ PROJECTED COSTS and PATH FORWARD
Initial prototypes have demonstrated proof of concept. Next generation prototypes will include improved battery technology (lithium ion) and permanent magnet alternator systems for lower speed electricicty generation. The total REMOTA™ budget consists of an Opening Phase for which includes 3 tracks of initial development stages: 1) REMOTA™platform design; 2) energy storage and generation configurations; 3) eMobility Decisionware™ along with the corresponding prototype testing and validation followed by the Second Phase which includes producing the comprehensive integrated solution and field testing and then concluding with the Final Phase which includes the Monitoring and Verification of Solution Integrity and Performance with end users.
The Mobile Energy Solution Market is comprised of military organizations, utility companies, disaster management organizations, energy services and other industrial and commercial companies. Each customer segment offers distinct value and opportunities. Overall pricing per mobile platform is dependent on platform size and capabilities along with the amount of energy stored and produced. As the platform size, features and the kWh output increases, so does the price. However, post project, the initial unit prices are estimated to range from $25,500 - $95,000 for four different size power platforms ranging in capacity from 14 to 56 kWh.
There are many drivers for large utility customers to consider implementation of microgrids such as the REMOTA™ renewable, mobile power trailer. Increasing incidents of serious storms causing long‐term power outages in densely populated areas and new threats such as cyber‐attacks are highlighting vulnerabilities to critical missions. The growing availability of financial incentives including demand response and grid services make on‐site power generation more viable. There are many scenarios and regions of the country where both utilities and customers can benefit from a properly implemented and operated microgrid through improved power reliability and more efficient energy generation
