HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

According to the European Environment Agency (EEA), maritime transport is responsible for more than 3% of the total carbon emissions in the European Union. The methanol is mixed with water, then evaporated by applying heat and fed into the preheated reactor, where the mix of methanol and water is converted into hydrogen and CO 2.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.

Researchers find that abiotic methane can charge deepsea Arctic gas hydrates

Green Car Congress

Researchers from the Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) at the Arctic University of Norway have discovered a growing Arctic abiotic methane- and methane hydrate–charged sediment drift on oceanic crust in the deep Fram Strait of the Arctic Ocean. —co-author and CAGE director Jürgen Mienert.

US DOE awards ~$5M to expand research on methane hydrates

Green Car Congress

When methane hydrates are “melted,” or exposed to pressure and temperature conditions outside those where the formations are stable, the solid crystalline lattice turns to liquid water, and the enclosed methane molecules are released as gas. Earlier post.). DOE Investment: approximately $390,000. ? DOE Investment: approximately $650,000.

Berkeley Lab scientists find that large undersea methane releases could overwhelm the Arctic Ocean’s ability to consume the gas

Green Car Congress

A two-part study by scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Los Alamos National Laboratory provides a detailed scenario based on a novel combination of two computer models of how climate change could impact millions of tons of methane frozen in sediment beneath the Arctic Ocean.

Researchers Find Warming Arctic Current Triggers Release of Methane from Methane Hydrate

Green Car Congress

Methane released from gas hydrate in submarine sediments has been identified in the past as an agent of climate change. The data were collected from the royal research ship RRS James Clark Ross, as part of the Natural Environment Research Council’s International Polar Year Initiative. Westbrook, G.

Researchers Find That Unusual Arctic Warmth and Tropical Wetness Likely Cause for Methane Increase

Green Car Congress

This kind of climate condition typically brings wetter-than-normal conditions in some tropical regions and cooler sea surface temperatures in the central and eastern tropical Pacific Ocean. The gas also escapes during fossil fuel extraction and distribution and is emitted during fires. It can persist for as long as two years.
