“…The nationalization of hydrocarbon sector, in 1971, had affected deeply the government's policies as this sector took an increasingly share of the national economy. Currently, hydrocarbons present 97% of the national exportations, 35.9% of national GDP and over two thirds of taxes and government incomes [4]. Furthermore, Algeria accounts 12.2 billion barrels and 4504 Bcm of crude oil and gas reserves respectively, ranging the country 7 th in the world [34].…”

“…The principal goals of these policies are to increase the renewable energy ratio, decrease the fossil energy dependency and limit the greenhouse gases GHG emissions. To face the challenges mentioned above, more eco-friendly and more suitable alternatives renewable energy sources are progressively coming into view [3][4][5]. Alternative fuels have been in focus for several years due to the challenges of mitigating GHGs in the transportation sector.…”

The expanding and highly greedy Algerian transport sector is totally depending on petro-products, due to the rising numbers of automobile fleets and the excessive dependence on road transportation. Irrecoverable Greenhouse gases GHGs emitted by this sector are constantly increasing. As a result, consumption of diesel and gasoline reached record levels. Consequently, there is a strong need of cleaner, eco-friendly and economically viable alternative fuels. Biofuels, electric, compressed natural gas CNG, liquefied petroleum gas LGP vehicles, are expected to play a crucial role in meeting energy and environmental policies targets. In this paper, the Algerian transport sector perspectives and Greenhouse gases mitigations, in different shaped scenarios based on semi-empirical models, are analyzed and discussed. For adequate policy shaped in a scenario, in 2050, annual Algerian consumption could decrease up to 35%, 43% of CO2 emissions and 73% of NOx emissions could be mitigated compared to no-intervention scenario. These promising findings indicate the huge potential of resource diversification on the transportation sector. Therefore, implementing such policies is fundamental for a durable Algerian’s transportation sector transition policy.

The reduction of energy consumption is an important key not only to improving the performance of the Algerian economy but also to contributing to the effective mitigation of greenhouse gas emissions. This study provides a decomposition analysis of a set of sub-sectors belonging to the non-energy industry in terms of energy use. The Logarithmic Mean Divisia Index (LMDI) is used to identify the factors affecting the change in energy consumption between 2002 and 2015. It is estimated that the energy consumption of Algeria's non-energy industries has increased from 4904 ktoe in 2002 to 8818 ktoe in 2015. The findings reveal that the increase in energy consumption in Algeria’s non-energy industry was due to the activity effect, whereas the structure and intensity effects contributed to the decrease. The increase in energy consumption due to the activity effect is largest in the construction materials industry. The intensity effect has a significant impact on energy consumption in the iron and steel, mechanical, electronic, and electrical equipment industries. Furthermore, the construction materials industry had a large share of the total change in energy consumption for the entire non-energy industry during 2002–2015, accounting for 136%.

“…According to IRENA [3], the global interest for methanol has dramatically increased in recent decades, and the environmental impacts will be tremendous (~1.5 Gt CO2 /y) if it is produced by natural gas and coal solely. These facts make clear that the adoption of low-carbon solutions for methanol production is more than essential [6,7].…”

This study presents design considerations and an evaluation of a full-scale process chain for methanol and advanced drop-in fuel production derived from lignite/solid recovered fuel (SRF) feedstock. The plant concept consists of a high-temperature Winkler (HTW) gasifier coupled with an air separation unit (ASU), which provides a high-purity (99.55%) gasification oxidant agent. The concept includes the commercially proven acid gas removal (AGR) system based on cold methanol (e.g., Rectisol® process) for the removal of BTX and naphthalene components. With the involvement of Rectisol®, an almost pure CO2 off-gas stream is generated that can be further stored or utilized (CCS/CCU), and a smaller CO2 stream containing H2S is recovered and subsequently driven to the sulfur recovery unit (e.g., Claus process). One of the potential uses of methanol is considered, and a methanol upgrading unit is implemented. The overall integrated process model was developed in the commercial software Aspen PlusTM. Simulations for different feedstock ratios were investigated, ensuring the concept’s adaptability in each case without major changes. A number of parametric studies were performed concerning (a) the oxygen purity and (b) the reformer type, and a comparison against alternative methanol production routes was conducted. Simulations show that the proposed system is able to retain the cold gas efficiency (CGE) in the range of 79–81.1% and the energetic fuel efficiency (EFE) at around 51%. An efficient conversion of approximately 99.5% of the carbon that enters the gasifiers is accomplished, with around 45% of carbon being captured in the form of pure CO2. Finally, the metrics of EFE and total C for the conversion of methanol to liquid fuels were 40.7% and 32%, respectively, revealing that the proposed pathway is an effective alternative for methanol valorization.
