Fuel cells were invented over a century ago and are a proven technology; organizations such as NASA have been using the technology since the 1960’s. Unfortunately, due to their very high cost and inconsistent field life performance, existing SOFC technology has been unable to meet market acceptance. That is, until now.
Experts have long agreed that SOFCs have the potential to deliver the highest efficiency of any fuel cell technology. With low cost ceramic materials, and extremely high electrical efficiencies, SOFCs can deliver attractive economics.
Solid Oxide Fuel Cell (SOFC)
SOFC’s run at extremely high temperature which gives them significantly higher electrical efficiencies, and fuel flexibility, both of which contribute to better economics. However, SOFC also present considerable engineering challenges associated with Thermal Stress and Current Collection. In general terms, SOFC’s using a Planar design do so as Current Collection is much simpler, resulting in lower cost to market, but they have proven to have chronic Thermal Stress issues which result in poor field life and very high maintenance costs.
SOFC’s using as Tubular based design have proven Thermal Stress advantages resulting in reliable field life performance, but have proven to have significantly higher design and manufacturing costs associated with Current Collection, making them too expensive for the market to bear.
Veridyne Power is currently in the process of demonstrating a tubular based SOFC technology operating on Natural Gas that is expected to resolve the outstanding technical, operational and financial impediments to large, commercial scale implementation of SOFC technology. Veridyne Power Corporation is excited to develop a new tubular design Solid Oxide Fuel technology targeting lowest capital expenditure requirements together with the lowest field operating and maintenance expenditures.
SOFC’s have greater power efficiency, with 60-65% electro-chemical and an additional 15-20% for a combined overall electrical efficiency of 80% This is equivalent to a 50% (or more) fuel savings and delivers much higher environmental credentials:
▪ 99% lower NOX and SOX emissions
▪ 50-75% CO2 emissions
▪ Less cost and/or requirement for CO2 collection and sequestration
