Japanese Compact System Generates Electricity from Hot Water at only 90 Degrees Celsius

Keywords: Eco-business / Social Venture Manufacturing industry Renewable Energy 

ULVAC-RIKO Inc., which manufactures and sells heat-analysis devices, announced May 31, 2011, that it has developed a highly efficient, portable, and compact three-kilowatt electricity generation system that uses hot water at only 90-degree Celsius to produce power.

The demand for renewable energy sources continues to grow, especially in view of diminished oil supplies and the need to prevent global warming. Since the Great East Japan Earthquake, there is also more demand for power generation technologies that use previously untapped energy sources. Lower-temperature heat sources, which commonly exist as factory waste heat or from hot springs, have largely been ignored up to now because existing systems need enough heat for a generation capacity of 50 kilowatts (kW) or more, requiring high amounts of heat and expensive initial costs, including installation.

The ULVAC-RIKO system can generate a small amount of power of 3 to 12 kW using water at low temperatures of 150 degrees Celsius or less. The system is compact enough to fit into a small truck. Also, the generator runs quietly enough to that noise concerns will not be a factor in selecting installation sites. These advantages give this new generator good potential as a source of as-yet untapped energy.
