First Qantas US-Australia biofuel flight; Carinata feedstock, Honeywell process

Green Car Congress

Qantas made the world’s first dedicated biofuel flight between the United States and Australia, Qantas QF96 from Los Angeles to Melbourne (a Boeing Dreamliner 787-9), over the weekend. The 15-hour trans-Pacific flight operated with approximately 24,000 kg of 10% biofuel blend, saving 18,000 kg in carbon emissions.

Ensuring Underwater Robots Survive in Hot Tropical Waters

Cars That Think

“Tropical conditions can cause systems to overheat or prevent high-density lithium batteries from recharging,” says Melanie Olsen, who is a project director of the Australian Institute of Marine Science’s (AIMS) ReefWorks , a technology testing and evaluation facility in northern Australia.

Fallout from Australia’s Week Of Bushfires May Affect Victoria Water Supplies For 30 Years

Green Car Congress

Dehydrated soils and burned forests around Melbourne Water reservoirs will draw more water than normal as they replenish in coming years, while increased sediment runoff around some reservoirs will reduce reservoir capacity. Melbourne’s water is stored in nine separate reservoirs, which helps protect supply during severe bushfires.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy.

Ocean Salinities Show an Intensified Water Cycle; Large Salinity Changes Will Eventually Influence Ocean Circulation

Green Car Congress

A new study co-authored by CSIRO (Australia) scientists Paul Durack and Dr. Susan Wijffels finds evidence that the world’s water cycle has already intensified. The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. Durack and Wijffels. ºC since 1950.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years.

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.
