Comments Off on Airbus, Siemens, Rolls-Royce partner to build a hybrid-electric plane

Hybrid-electric commercial planes could be a reality if Airbus , Rolls-Royce , and Siemens are successful. The three companies recently teamed up to work on the E-Fan X technology demonstrator that could hit the skies in around three years. Siemens, Airbus, and Rolls-Royce announced their collaboration recently at the Royal Aeronautical Society in London. They’ll come together to create what they call a near-term flight demonstrator that could fly in 2020. Out of four gas turbine engines on the aircraft, one will be replaced with a two-megawatt electric motor , and they’ll work towards switching out a second. Related: Airbus’ flying electric taxi is on track to soar next year Each company has a role to play: Airbus is in charge of overall integration and control architecture for the batteries and hybrid-electric propulsion system. Rolls-Royce is in charge of the two-megawatt generator, power electronics, and turbo-shaft engine. And Siemens will provide the two-megawatt electric motors and a power control unit – and an inverter, power distribution system, and DC/DC converter. According to an Airbus press release on the project, “The E-Fan X demonstrator will explore the challenges of high-power propulsion systems, such as thermal effects, electric thrust management, altitude and dynamic effects on electric systems and electromagnetic compatibility issues. The objective is to push and mature the technology, performance, safety, and reliability enabling quick progress on the hybrid-electric technology.” The companies said some of the major challenges facing the aviation sector are lowering dependence on fossil fuels and boosting efficiency. They’re working to meet the European Commission’s Flightpath 2050 Vision for Aviation, which entails a 75 percent and 90 percent reduction of carbon dioxide and nitrogen oxide , respectively, as well as slashing noise by 65 percent. Airbus said existing technologies cannot achieve these targets, so the companies are pursuing alternatives like electrification. The statement said, “Electric and hybrid-electric propulsion are seen today as among the most promising technologies for addressing these challenges.” Via Airbus Images via Airbus

Britain to ban new diesel and petrol cars in 2040

Comments Off on Britain to ban new diesel and petrol cars in 2040

British government ministers think low air quality poses the biggest environmental threat to public health , but that threat is avoidable. They aim to clean up the skies by targeting emissions-spewing vehicles. Following a similar move in France , Britain is to ban the sale of diesel and petrol cars from 2040. Nitrogen oxide is plaguing the air in the United Kingdom. Earlier this year, London smashed annual air pollution limits in a mere five days – and Greenpeace said diesel vehicles were the single biggest source of air pollution in the city. Now the country could commit to ban sales of those polluting cars as part of their clean air plan. The move could even include hybrid vehicles . Related: France to ban all diesel and petrol cars in just over 20 years The government endeavored to move away from taxes on polluting cars, although they’d been encouraged to introduce charges for cars entering clean air zones. They wanted taxes to be a last resort, and a government spokesperson pointed to a £3 billion, around $3.9 billion, program to clean dirty air near roadways that will offer funding to advance local efforts, like retrofitting public transportation , reprogramming traffic lights, and altering road features like speed humps and roundabouts. £1 billion, or $1.3 billion, of the air quality package could go towards promoting low-emissions cars, with £100 million, or $1.3 million, devoted to boosting charging infrastructure for electric vehicles . More money could go to a green bus fund, cycling and walking, and low-emission taxis. The clean air plan has been part of a lengthy legal battle, with the final plan due by the end of July. Environmentalists weren’t impressed with a draft report seen earlier, which some lawyers said was much weaker than they wanted. Environment secretary Michael Grove will hope for a better response, according to The Guardian, when he puts out the final document this week.

How many people may have died due to Volkswagen’s emissions cheating?

Comments Off on How many people may have died due to Volkswagen’s emissions cheating?

Pollution can kill, there’s no disputing that fact. So, if pollution kills, how many people might have died as a result of the additional pollutants emitted by Volkswagen vehicles equipped with software that allowed them to cheat on emissions standards ? That’s the question posed by a pair of New York Times writers , who dug into the issue and came up with some grim estimates. Their numbers range from about 106 deaths to roughly 146 deaths since 2008 as a result of the 46,000 tons of additional tailpipe emissions from the Volkswagen vehicles.

Comments Off on The surprising way air pollution levels in the Middle East are affected by years of conflict

A new study has revealed significant changes in air pollution levels in the Middle East, with economic crisis, humanitarian catastrophe, and war being contributing factors. High resolution satellites have been collecting data from major cities since 2005 and the results have flown in the face of previous predictions of the region’s emissions.
