Anaergia to supply CO2 to European Energy A/S for green e-methanol production as fuel for container ships

Green Car Congress

Biogenic carbon dioxide is carbon dioxide that is released during the decomposition of organic matter such as food waste. All Anaergia plants use organic waste material to produce biogas, which is composed of methane and carbon dioxide. Moller - Maersk is having built to operate on this carbon-neutral fuel.

Researchers find bio-inspired high-tech surfaces on hulls could greatly reduce drag and CO2 emissions of ships; up to 1% of global CO2

Green Car Congress

Together, they burn an estimated 250 million tonnes per year and emit around one billion tonnes of carbon dioxide into the air—about the same amount as the whole of Germany emits over the same period. The main reason for this is the high degree of drag between hull and water, which constantly slows the ship down. Busch et al.

Study finds increased CO2 enhancing plankton growth; opposite of expected

Green Car Congress

Coccolithophores —unicellular, eukaryotic phytoplankton (algae)—have been increasing in relative abundance in the North Atlantic over the last 45 years, as carbon input into ocean waters has increased. The CPR survey was launched by British marine biologist Sir Alister Hardy in the early 1930s.

Study finds ocean warmth and atmospheric CO2 concentrations were decoupled during Miocene period; suggests role of ocean circulation, clouds and water vapor feedback

Green Car Congress

A new study based on deep-sea sediment cores, published in the journal Nature , has found that during the Miocene period ~12–5 million years ago, climate was decoupled from atmospheric carbon dioxide concentrations. The cores were retrieved by marine scientists working aboard the drillship JOIDES Resolution. —Jonathan LaRiviere.

Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Synthesis Study Finds Ocean Acidification from CO2 Emissions Could Increase by 150% by 2050; Substantial Irreversible Damage to Ocean Ecosystems

Green Car Congress

This is an increase 100 times faster than any change in acidity experienced in the marine environment over the last 20 million years, giving little time for evolutionary adaptation within biological systems, the report says. Carbonate ion concentrations are now lower than at any other time during the last 800,000 years.

New LLNL technique for CO2 capture also produces green hydrogen and alkalinity to offset ocean acidification

Green Car Congress

Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification. However, further research is needed, the authors said.
