ORNL computational study finds 15% bio-oil mixture in two-stroke marine engines can cut NOx 13% with efficiency parity

Green Car Congress

A team at Oak Ridge National Laboratory (ORNL) has developed a new computational model of a two-stroke scaled marine engine, with reduced chemical mechanisms for diesel, biodiesel, bio-oil, and polycyclic aromatic hydrocarbons (PAH). This work aims to develop a computational model of a scaled marine engine. —Chuahy et al.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

BASF partners with China BlueChemical and Wuhuan Engineering to develop new technology for use of CO2-rich marine gas

Green Car Congress

to promote low-carbon development and utilization of marine gas resources. In the Dongfang Industrial Park of Hainan Province, China BlueChemical extracts large quantities of such offshore natural gas (marine gas) from gas fields in the South China Sea. —Wang Weimin, Chairman of China BlueChemical Limited Company.

Study suggests microbe produces methane from crude oil all by itself

Green Car Congress

Crude oil and gas naturally escape from the seabed in many places known as seeps. This microbe, an archaeon named Methanoliparia , transforms the hydrocarbons by a process called alkane disproportionation: it splits the oil into methane (CH 4) and carbon dioxide (CO 2 ). © Max Planck Institute for Marine Microbiology).

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. With an ability to absorb more than 30 times its weight in oil, the sponge could be used to clean up oil spills inexpensively and efficiently without harming marine life. —Vikas Nandwana.

Statoil greenlights $7B Mariner heavy-oil project in UK North Sea

Green Car Congress

Statoil has made the investment decision to develop the Mariner heavy oil field development in the UK North Sea. The Mariner Field is located on the East Shetland Platform of the UK North Sea approximately 150 km east of the Shetland Isles. The heavy oil project will require pioneering technology in order to be developed.
