Note: 2025 data are an estimate based on data through September. Distillate fuel oil includes marine gasoil (MGO), marine diesel (MDO), and low-sulfur marine gasoil (LSMGO). Heavy fuel oil includes marine fuel oil (MFO).

When the International Maritime Organization’s lower marine sulfur limit known as IMO 2020 took effect in January 2020, commercial shippers pivoted sharply to fueling their vessels with low-sulfur fuel oil (LSFO). In the years since, high-sulfur fuel oil has reclaimed some market share, as a growing number of commercial vessels install sulfur scrubbers that allow operators to use the heavier, cheaper fuel oils while complying with the new sulfur emission limits.

Bunker fuel refers to any fuel supplied to ships to power

Cambridge researchers have engineered a solar-powered “artificial leaf” that mimics photosynthesis to make valuable chemicals sustainably. Their biohybrid device combines organic semiconductors and enzymes to convert CO₂ and sunlight into formate with high efficiency. It’s durable, non-toxic, and runs without fossil fuels—paving the way for a greener chemical industry.

Synopsis

The Cyberinfrastructure for Sustained Scientific Innovation (CSSI) program seeks to enable funding opportunities that are flexible and responsive to the evolving and emerging needs in cyberinfrastructure (CI). The program continues to emphasize integrated CI services, quantitative metrics with targets for delivery and usage of these services, and community creation.

The CSSI program anticipates three classes of awards:

Elements: These awards target small groups that will create and deploy robust services for which there is a demonstrated need, and that will advance one or more significant areas of science and engineering. Framework Implementations: These awards target larger, interdisciplinary teams organized around the development and application of services aimed at solving common research problems faced by NSF researchers in one or more areas of science and engineering, and resulting in a sustainable community framework providing CI services to a diverse community or communities.
