6111Cost Reduction

The high capital cost for fuel cells is by far the largest factor contributing to the small market penetration of fuel cell technology. The high capital cost (on a $/kW basis) has led to an electric power sector wary of installing fuel cells or using them in other systems (e.g., transportation applications). Reducing the installed cost of fuel cell technology is perhaps the most important driver of fuel cell research, development, and demonstration (RD&D) today. This RD&D encompasses many aspects of the fuel cell industry and research community. Specific areas in which cost reductions are being investigated include (1) materials, (2) complexity of integrated systems, (3) temperature constraints, (4) manufacturing processes, (5) power density (footprint reduction), and (6) benefit from economies of scale (volume) through increased market penetration.

Solar Stirling Engine Basics Explained

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
