Solid Oxide Fuel Cell -- Acumentrics RP500


Marsh Creek, LLC, and Acumentrics Corporation of Massachusetts have come together to bring you the RP20 Solid Oxide Fuel Cell (SOFC). Acumentrics is known for developing highly-reliable power products for the harshest environments. Their portfolio of rugged power electronics products includes 60,000 units deployed globally in military and industrial sites for multiple applications. Marsh Creek is the energy expert in Alaska and in arctic climates, and we are the exclusive distributor and service provider for Acumentrics RP20 (now called RP500) in Alaska.

What is a Solid Oxide Fuel Cell and how does it work?
A solid oxide fuel cell is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. While batteries consume their reactants and must be recharged, fuel cells function as long as there is fuel. Hydrogen and oxygen are extracted from the fuel and atmosphere to create electricity, heat, and water vapor. Fuel cells are more efficient than engines because there is no energy loss to mechanical motion. The Acumentrics RP500 is the first fuel cell-based power system designed "from the ground up" to meet the specific needs of corrosion protection for customers in the oil and gas industry.

The Acumentrics RP500 Solid Oxide Fuel Cell is designed for minimal annual maintenance of air filter replacement, checking fuel filters, desulfurizer canisters, and fuel delivery (depending upon tank size). At 500 continuous watts, the unit will use 7 ft3/hr of natural gas, and .08 gal/hr of propane. Local collection and storage of system data is standard and can be accessed through Ethernet cable connection and/or transmitted through satellite link of cellular network. Systems can be connected in parallel for higher output power applications.  

What are the potential applications of the innovation?
In addition to the primary application of supplying DC power to Impressed Current Cathodic Protection (ICCP) systems, the RP500 is also capable of simultaneously powering additional loads at off-grid oil and gas sites including:

     Impressed Current Cathodic Protection (ICCP)
     Chemical Injection Pumps
     SCADA Systems
     Gas Analyzers & other instrumentation
     Remote Control Valves
