摘要:

Unlike other articles in this issue, here we address not so much how to manage a demonstration project as what to demonstrate and when. Specifically, the article identifies five characteristics of successful large-scale technology demonstration programs, based on experience with fuel cell technologies: 1) a robust technology that has not yet significantly penetrated the marketplace; 2) reduced uncertainties in R&D (in this case, movement on codes and standards impacting design, permitting, and installation); 3) the active involvement of private sector advocates in sponsoring demonstration activities and brokering partnerships; 4) a strong federal role; and 5) economic incentives. Each of these will be discussed in turn, supported by examples. The article also describes fuel cell technologies and offers guidance on potential applications for both power generation and transportation.

摘要:

Several applications of solar energy have proven viable in the energy marketplace, due to competitive technology and economic performance. One example is the parabolic trough solar collectors, which use focused solar energy to maximize efficiency and reduce material use in construction.

摘要:

In an era of heightened awareness of energy efficiency and the associated environmental impacts, many industries worldwide are exploring “environmentally friendly” technologies that provide equivalent or improved performance while reducing or eliminating harmful side-effects. The refrigeration and air-conditioning industry, due to its reliance on CFCs and HCFCs, has invested in research in alternatives to the industry standard vapor compression machines. One alternative technology with great promise is chemical absorption. Absorption chillers offer comparable refrigeration output with reduced SO2, CO2, and NOxemissions. Absorption chillers do not use CFCs or HCFCs, refrigerants that contribute to ozone depletion and global warming. Additionally, gas-fired absorption chillers can save significant amounts in energy costs when used in combination with a vapor compression chiller in a hybrid system. The hybrid system can take advantage of the comparatively low price of natural gas (per unit ton) and rely on the high performance of vapor compression when electricity prices are lower.
