“…The viscosity and total acid number (TAN) are higher than the permissible limit for DFB but well within the range for RMB 30. Tyrovola et al (2017) highlighted the requirement of low sulfur content in the future of marine fuels, which is planned to be 0.5%. As the sulfur content in the animal fat feedstock is very low, the %S in the bio-oil is merely 0.016%.…”

Unused animal waste rendered fat is a potential feedstock for marine biofuels. In this work, bio-oil was generated using hydrothermal liquefaction (HTL) of nitrogen-free and low sulfur rendered bovine fat. Maximum bio-oil yield of 28 ± 1.5% and high heating value of 38.5 ± 0.16 MJ·kg‒1 was obtained at 330 °C at 50% animal fat solid load and 20 min retention time. The nitrogen and sulfur content were negligible, making the produced bio-oil useful marine biofuel, taking into account current stringent regulations on NOx and SOx emissions. The economic analysis of the process, where part of the bovine fat waste is converted to the bio-oil and the semi-solid residues can be used to supply the heat demand of the HTL process and alternately generate electricity, showed that our process is likely to generate a positive profit margin on a large scale. We also showed the growing economic importance of electricity in the revenues as commercial production becomes more energy efficient.

“…The shipping sector is responsible for about 90% of international freight transport [1]. Emitting 2.8% of worldwide Greenhouse Gas (GHG) emissions, the share in air pollution of the shipping sector is about the size of Germany [1,2]. Although the relative emissions per unit of cargo are low compared to other transport modes, the total share in emissions of the shipping industry is significant [3][4][5].…”

In this study, various scenarios were developed that correspond to estimations of future biomass availability and biofuel demand from the maritime industry. These marine biofuel demand scenarios were based on the Greenhouse Gas (GHG) reduction targets of the Renewable Energy Directive II (RED II) and the International Maritime Organization (IMO). A multi-objective Mixed Integer Linear Programming (MILP) model was developed which is used to optimize the Well-to-Tank (WtT) phases of each studied scenario. This resulted in an overview of the most feasible use of feedstocks, deployment of new conversion technologies and trade flows between regions. Additionally, the results provided insight into the costs and emission reduction potential of marine biofuels. By analyzing the results from this study, improved insight into the potential of drop-in biofuels for reaching the proposed emission reduction targets for the maritime sector was developed. A trade-off between costs and emissions was found to result in potential GHG reductions between 68–95% compared to Heavy Fuel Oil (HFO) for 800–2300 EUR/ton. More specifically, 80% GHG reduction compared to HFO can be achieved at fuel costs of between 900–1050 EUR/ton over the studied time period.

“…. Filling cars with biofuels is a fairly widespread phenomenon, but the use of biofuels by sea transport is still rather limited is still rather limited and at the same time it is a new solution that has a fairly signifi cant potential and may make up around 10% of the total amount of marine fuel by 2030 [3,4]. It should be added that shipping is currently one of the fastest growing and most eff ective directions in the transport sector and plays an important role in the global economy.…”

In the article, a qualitative and quantitative analysis of motor biofuels for water and land types of transport is carried out. In that context, the possibility of increasing their effi ciency is demonstrated through the introduction of the rapid pyrolysis process, which allows up to 25% of renewable fuels to be used in a mixture with conventional diesel. It is established that the most eff ective way is the joint processing of bio-oil with oil products on existing production facilities, which does not require the construction of new plants, signifi cantly reduces the dependence on fossil oil, and the obtained gasoline and diesel fuel have good performance characteristics and their use practically does not require changes in the fuel consumption infrastructure. Sažetak U ovome radu provedena je kvalitativna i kvantitativna analiza motornih biogoriva u vodenom i kopnenom prijevozu. U tom kontekstu prikazuje se mogućnost povećanja učinkovitosti goriva uvođenjem brzog procesa pirolize, kojim se 25% obnovljivih goriva može koristiti u mješavini s konvencionalnim dizelskim gorivom. Utvrđeno je da je najučinkovitiji način obrada bionafte zajedno s naftnim proizvodima u postojećim proizvodnim pogonima, što ne zahtijeva gradnju novih postrojenja, značajno smanjuje ovisnost o fosilnim gorivima, a dobiveno naftno i dizelsko gorivo pokazuju dobre izvedbene karakteristike, dok njihova uporaba ne zahtijeva promjene u infrastrukturi potrošnje goriva.
