Despite the growing sales of electric vehicles and electrification as a means to alleviate the
growing problem of climate change, it is largely overlooked that internal combustion engine …

The shipping industry has reached a higher level of maturity in terms of its knowledge and
awareness of decarbonization challenges. Carbon-free or carbon-neutralized green fuel …

As an efficient hydrogen carrier, ammonia (NH 3) has great potential to realize the target of
carbon neutralization. In this paper, a natural gas-ammonia dual-fuel engine model has …

Ammonia (NH3) is an attractive low-carbon fuel and hydrogen carrier. However, losses and
inefficiencies across the value chain could result in reactive nitrogen emissions (NH3, NOx …

Alternative fuels are crucial to decarbonize the European maritime transport, but their net
climate benefits vary with the type of fuel and production country. In this study, we assess the …

This study aimed to compare hydrogen, ammonia, methanol, and waste-derived biofuels as
shipping fuels using life cycle assessment, to establish what potential they have to contribute …

This study investigates the novel approach of direct liquid ammonia injection into the
combustion chamber of a compression ignition engine. Unlike traditional gaseous ammonia …

Pilot-diesel-ignition ammonia combustion engines have attracted widespread attentions
from the maritime sector, but there are still bottleneck problems such as high unburned NH3 …

Ammonia, as a hydrogen-derived fuel, primarily emits N 2 O and NO x when burned in an
engine. The emissions originate from ammonia fuel and nitrogen in the air. In this paper, the …

Decarbonization is crucial to combat climate change. However, some decarbonization
strategies could profoundly impact the nitrogen cycle. In this Review, we explore the …
