An overview of research efforts at NASA Glenn Research Center (GRC) in low-emission combustion technology that have made a significant impact on the nitrogen oxides (NOx) emission reduction in aircraft propulsion is presented. The technology advancements and their impact on aircraft emissions are discussed in the context of NASA’s Aeronautics Research Mission Directorate (ARMD) high-level goals in fuel burn, noise and emission reductions. The highlights of the research presented here show how the past and current efforts laid the foundation for the engines that are flying today as well as how the continued technology advancements will significantly influence the next generation of aviation propulsion system designs.

Low Carbon Energy

The influence of low-carbon energy on economic development is a vital issue. Using the provincial panel data in China from 2000 to 2017, this work investigated the aggregate effects of low-emission electricity. The results showed that 1) when the ratio of low-emission electricity to total electricity increases by 1%, the GDP per capita will increase by 0.16% and CO2 emissions will decrease by 0.848%. In other words, low-emission electricity can achieve the goal of low-carbon economic development; 2) the self-supply of low-emission electricity, rather than trade and efficiency, is the main reason for China’s boosted economic growth; and 3) low-emission electricity increases the regional economic gap in China. The effects of pollution inhibition and economic promotion on low-emission electricity in developed areas are significantly greater than those in less developed areas. Thus, the low-emission electricity policy in China should benefit the economy and avoid the excessive economic gap among regions. Policymakers should vigorously promote the low-emission electricity revolution and pay attention to the inclination of energy policy to the central and western regions.

To find low carbon heating measures in swine farms in Beijing China, A study of swine houses with area of 920 m2in swine farms in Beijing China was conducted and economic performance, emission reduction of ground-coupled heat pump (GCHP) heating system, coal fired heating system and other heating systems were analyzed and compared. The results showed that the initial investment of ground-coupled heat pump system was more than that of the coal fired heating system, the relative running cost of the heating systems of ground-coupled heat pump, coal fired, electricity resistance and natural gas was 0.86, 1.00, 3.17 and 1.22, respectively. CO2avoidances of GCHP heating systems were 57% and 73%, respectively, compared with conventional coal fired heating system and electricity resistance heating.
