Ammonia, with its high hydrogen content, serves as an efficient energy carrier and a potential replacement for traditional fossil fuels in achieving the United Nations' carbon neutrality goal. It also offers significant advantages over production, storage, transportation. Extensive research has been conducted on use of ammonia transportation power generation, collectively referred to combustion (AFC). However, there remains lack systematic review this area, which study aims address. Using bibliometric techniques, data from publications spanning 2000 2024 were gathered Web Science database, revealing that publication numbers remained low until 2015 but increased significantly 2016 onward. This systematically analyzes numerical experimental studies characteristics technologies across last forty years. The primary challenges identified AFC include prolonged ignition delay, laminar burning velocity, NOx emissions. To mitigate these challenges, various such fuel blending auxiliary have proposed. highlighted concerning technology readiness levels AFC. address gap, comprehensive examination applications internal engines, marine aircraft gas turbines generation was undertaken. evaluation encompassed objectives, gaps, methods enhancing performance, assessments levels. findings investigation make substantial contributions field, offering valuable insights into prospects sustainable combustion.

Renewable Methanol as a Fuel for Heavy-Duty Engines: A Review of Technologies Enabling Single-Fuel Solutions

Energies, Год журнала: 2024, Номер 17(7), С. 1719 - 1719

Опубликована: Апрель 3, 2024

To meet climate targets, a global shift away from fossil fuels is essential. For sectors where electrification impractical, it crucial to find sustainable energy carriers. Renewable methanol widely considered promising fuel for powering heavy-duty applications like shipping, freight transport, agriculture, and industrial machines due its various production methods. While current technological efforts focus mainly on dual-fuel engines in future progress hinges single-fuel solutions using renewable achieve net-zero goals the sector. This review examines research status of technologies enabling as sole applications. Three main categories emerged literature: spark-ignition, compression-ignition, pre-chamber systems. Each concept’s operational principles characteristics regarding efficiency, stability, emissions were analyzed. Spark-ignition concepts are proven cost-effective solution with high maturity. However, they face limitations knock issues, restricting power output larger bore sizes. Compression-ignition inherently do not suffer end-gas autoignition, but encounter challenges related ignitability low cetane number methanol. Nonetheless, methods achieving autoignition exist. obtain stable combustion at all load points, combination techniques will be required. Pre-chamber technology, despite lower maturity, holds promise extending limit enhancing efficiency by acting distributed ignition source. Furthermore, mixing-controlled show potential eliminating associated size limitations. The concludes comparing each technology identifying gaps work.
