As the climate crisis intensifies, the pressure on the aviation industry to cut emissions increases. And now, the industry has taken a step forward, with a successful test flight of a hydrogen-electric engine, which produces no carbon emissions.
United Nations has a new goal of net-zero carbon emissions for the aviation industry by the year 2050.
Solar arrays that promise to generate happier, healthier cows and crops, while producing cheap electrons on the side, are being put into practice in France, following a series of government-led energy tenders with a difference.
Biofuel, any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas. Biofuel is commonly advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels, particularly within the context of rising petroleum prices and increased concern over the contributions made by fossil fuels to global warming. Many critics express concerns about the scope of the expansion of certain biofuels because of the economic and environmental costs associated with the refining process and the potential removal of vast areas of arable land from food production.
Biofuels are liquid fuels produced from renewable biological sources, including plants and algae. Biofuels offer a solution to one of the challenges of solar, wind, and other alternative energy sources. These energy sources have incredible potential to reduce our dependence on fossil fuels and yield environmental and economic benefits. But many of these sources have a limitation: they can’t replace liquid fuels such as jet fuel, gasoline, and diesel fuel that are critical to our transportation needs. That’s where biofuels could help.
Technology to remove the planet-warming greenhouse gas CO2 from our atmosphere must be urgently ramped up, leading climate experts say in a new report.
Scientists say big cuts in CO2 emissions won't be enough to limit global warming.
Biofuel is any kind of fuel that is directly derived from plant or animal matter, also known as biomass, and produces bioenergy. ‘Bio’ is used to depict the organic nature of this fuel source because it is not produced by a geological process like that of fossil fuels (petroleum and coal).
It's a new hydrogen-diesel hybrid engine affectionately known as "baby number two" that could help to decarbonise some of Australia's heaviest industries.
The test rig is large - it has its own room adjoining a lab and looks at first glance like many other large motors, but beneath its metallic skin could lie game-changing technology.
The Greenland ice sheet, one of the coldest and most remote regions of the world that serves a pivotal role in the Earth's climate, is now clearly feeling significant effects of climate change. Researchers found that central and northern areas of the sheet have recently seen the hottest temperatures in a millennium.
A startup company made aviation history Thursday when it successfully flew the largest ever hydrogen-electric powered aircraft, which could pave the way for less environmentally harmful flights.
