TECHNOLOGY

摘要

Scientists at the Energy Department s Pacific Northwest National Laboratory (PNNL) have made a commercially viable discovery-how to capture substantially more heat from low-temperature resources. In a market where binary working fluids are costly and traditionally inefficient, this advance harnesses a much larger sector of near-term geothermal potential through inventive, low-cost solutions. Payback on this novel technology is now estimated in certain operational conditions at under 36 days, and DOE expects a commercialization plan by first quarter 2014.
