The Impact

Heat production from a geothermal energy source is gaining increasing attention due to its potential contribution to the decarbonization of the European energy sector. Obtaining representative results of the environmental performances of geothermal systems and comparing them with other renewables is of utmost importance in order to ensure an effective energy transition as targeted by Europe. This work presents the outputs of a Life Cycle Assessment (LCA) performed on the Rittershoffen geothermal heat plant applying guidelines that were developed within the H2020 GEOENVI project. The production of 1 kWhth from the Rittershoffen heat plant was compared to the heat produced from natural gas in Europe. Geothermal heat production performed better than the average heat production in climate change and resource use, fossil categories. The LCA identified the electricity consumption during the operation and maintenance phase as a hot spot for several impact categories. A prospective scenario analysis was therefore performed to assess the evolution of the environmental performances of the Rittershoffen heat plant associated with the future French electricity mixes. The increase of renewable energy shares in the future French electricity mix caused the impact on specific categories (e.g., land use and mineral and metals resource depletion) to grow over the years. However, an overall reduction of the environmental impacts of the Rittershoffen heat plant was observed.

The Future

China has become the largest electric vehicle (EV) market in the world since 2015. Consequently, the lithium-ion battery (LiB) market in China is also expanding fast. LiB makers are continually introducing new types of LiBs into the market to improve LiBs’ performance. However, there will be a considerable amount of waste LiBs generated in China. These waste LiBs should be appropriately recycled to avoid resources’ waste or environmental pollution problems. Yet, because LiBs’ type keeps changing, the environmental impact and profitability of the waste LiB recycling industry in China become uncertain. In this research, we reveal the detailed life cycle process of EVs’ LiBs in China first. Then, the environmental impact of each type of LiB is speculated using the life cycle assessment (LCA) method. Moreover, we clarify how LiBs’ evolution will affect the economic effect of the waste battery recycling industry in China. We perform a sensitivity analysis focusing on waste LiBs’ collection rate. We found that along with LiBs’ evolution, their environmental impact is decreasing. Furthermore, if waste LiBs could be appropriately recycled, their life cycle environmental impact would be further dramatically decreased. On the other hand, the profitability of the waste battery recycling industry in China would decrease in the future. Moreover, it is essential to improve waste LiBs’ collection rate to establish an efficient waste LiB industry. Such a trend should be noticed by the Chinese government and waste LiB recycling operators to establish a sustainable waste LiB recycling industry in the future.

The Impact

The global demand for air conditioners (ACs) has more than tripled since 1990, with 1.6 billion units currently in use. With the rapid economic and population growth of countries located in the hottest parts in the world, this trend is likely to continue in the future. The aim of this study was to show the benefits of introducing air conditioners with different materials or different technologies such as inverters with high energy-saving performance on the environment and human health in Indonesia. To evaluate the environmental impacts of the different technologies, a cradle-to-grave life cycle assessment (LCA) of air conditioners was conducted using the life-cycle impact assessment method based on endpoint modeling (LIME3). As expected, the use stage has the largest global warming potential (GWP), representing more than 90% of the impact, whereas copper and nickel have the most important impact in terms of resource consumption (about 50%). We found that the impacts are heavily dependent on the country’s energy mix, but reduction can be achieved by introducing better technologies. The integration factors from LIME3 were then applied to estimate the external cost of each model; the results showed that the use stage also has the most influence. Even though the impact of climate change is important, air pollution impact must be seriously considered as its impact was found to be the highest (about 60% of the total impact). The external cost was finally compared to the possible benefits produced by the introduction of air conditioning technologies during their 10-year life cycle. We found that the impacts are twice that of the benefit for the best model (USD 2003 vs. 1064); however, the novelty of this study is that the benefit was also considered. In the future, developing countries should promote AC models with inverters, refrigerants with low global warming impact such as natural refrigerants, and encourage the recycling of units as soon as possible. The energy mix for electricity production is also a key parameter to consider.
