“…Energy security-i.e., the uninterrupted availability of natural resources for fuel consumption at an affordable price-is thus an important component of the motivation to incentivize the use of biofuels. Moreover, the penetration of renewable energy technologies in South Korea's fuel market, albeit limited so far, has also been driven by its strategic goal to downscale greenhouse gas (GHG) emissions by 37% by 2030 as compared with the business-as-usual scenario [3] (see [4] for an analysis of the implications of climate change (and urbanization) for precipitation and temperature in South Korea). In fact, according to the International Energy Agency [5], the transportation sector (including aviation and marine transportation) contributes almost one-fourth of the worldwide CO 2 emissions.…”

We investigated the biofuel potential of South Korea and the implications of the introduction of biofuels for the Korean fuel market. We approximated the upper-bound biomass potential from forestry residues, livestock manure, and staple crops and calculated the amount of fuel that could be produced using these different biomass feedstocks. Our assessment suggests that biomass can be used to produce a significant portion of the fuel consumed annually in South Korea, with the most promising feedstock being forestry residues. Out of all the technologies considered, the production of cellulosic ethanol from forestry residues could potentially impact the fuel market the most. The key novelty of our study lies in that we considered a broad portfolio of biofuel technologies and carefully examined their potential economic and environmental implications for South Korea given its biomass availability (which we estimated).

“…This gives rise to considerable global efforts to reduce its emissions. As a part of it, South Korea announced a target of reducing GHG emissions by 37% compared to Business As Usual (BAU) by 2030 in the Paris Agreement of the Intergovernmental Panel on Climate Change (IPCC) in 2016 [2].…”

Development of an Improved Model to Predict Building Thermal Energy Consumption by Utilizing Feature Selection

Humans spend approximately 90% of the daytime in buildings, and greenhouse gases (GHGs) emitted by buildings account for approximately 20% of total GHG emissions. As the energy consumed during building operation from a building life-cycle perspective amounts to approximately 70–90% of the total energy, it is essential to accurately predict the energy consumption of buildings for their efficient operation. This study aims to optimize a model for predicting the thermal energy consumption of buildings by (i) first extracting major variables through feature selection and deriving significant variables in addition to the collected data and (ii) predicting the thermal energy consumption using a machine learning model. Feature selection using random forest was performed, and 11 out of 17 available data were selected. The accuracy of the prediction model was significantly improved when the hour of day variable was added. The prediction model was constructed using an artificial neural network (ANN), and the improvement in the prediction accuracy was analyzed by comparing different cases of variable combinations. The ANN prediction accuracy was improved by 15% using the feature selection process compared to when all data were used as input data, and 25% coefficient of variation of the root mean square error (CVRMSE) accuracy was achieved.

“…This has led to, among other policies, government-funded research and development (R&D) activities regarding non-food feedstocks that could be used in the production of fuel for transportation. Still, at this point, there is urgent need for South Korea to efficiently manage its available natural resources in order to effectively support the growth of its bioeconomy (Kafle et al, 2017).…”

In this report, we investigate the biofuel potential of South Korea and the implications of the introduction of biofuels for the Korean fuel market. Our biomass assessment suggests that (theoretically) biomass can be used to produce a significant portion of the fuel consumed annually in South Korea, with the most promising feedstock being forestry residues. And out of all the technologies considered, the production of cellulosic ethanol from forestry residues could potentially impact the fuel market the most. The key novelty of our study lies in that we consider a broad portfolio of biofuel technologies and carefully examine their potential economic and environmental implications for South Korea given its biomass availability (which we actually estimate).
