Hydrogen planes not enough to green aviation: Study

https://str.sg/wAy5PARIS (AFP) - The aviation industry looks at hydrogen-fuelled planes as a solution to decarbonise the sector, but a report by an environmental group released on Wednesday (Jan 26) has found that they will only help limit CO2 emissions.

Using hydrogen as fuel produces no climate-warming CO2 when it burns, just water.Automakers and planemakers alike have been looking at it as a means to reduce the climate impact of the transportation sector, although currently most production of hydrogen creates emissions.

English Covid-19 study finds record prevalence in JanuaryOrigin of Covid-19 coronavirus. The WHO must investigate all evidence especially in countries where there are early reports of the coronavirus appearing. The US couldn't prevent a catastrophe with more than 800,000 deaths with the live with covid policy. While China maintaining a zero covid policy managed to keep deaths below 5,000. Which approach is preferable?

COVID-19 is less severe with Omicron than Delta, US study suggestsThe Omicron variant appears to result in less severe COVID-19 than seen during previous periods of high coronavirus transmission including the Delta wave, with shorter hospital stays, less need for intensive care and fewer deaths, according to a new US study. However, the fast-spreading Omicron varian Shocker LOL. Why sugarcoat? Scientific data shows Omicron is actually milder than Flu! It doesn’t replicate well in lungs or cause loss of taste & smell.💁‍♂️ But of cose, some vested interests still wanna fearmonger yall with high numbers to take endless boosters. Smh.

sg/wAy5 PARIS (AFP) - The aviation industry looks at hydrogen-fuelled planes as a solution to decarbonise the sector, but a report by an environmental group released on Wednesday (Jan 26) has found that they will only help limit CO2 emissions. Using hydrogen as fuel produces no climate-warming CO2 when it burns, just water. England will on Thursday ditch mask mandates and Covid-19 vaccine passes introduced to slow the spread of Omicron. Automakers and planemakers alike have been looking at it as a means to reduce the climate impact of the transportation sector, although currently most production of hydrogen creates emissions. But the study in the Nature Communications journal says this is no longer enough to keep identities private. The introduction into service of hydrogen-fuelled planes from 2035 is one way the aviation industry hopes it can reach net-zero carbon emissions in 2050. Britain has so far recorded more than 150,000 deaths from Covid-19, and daily infections peaked during the Omicron wave. If using hydrogen on long-haul aircraft is impossible due to the volume of gas needed,"on the short- to medium-haul flights where hydrogen aircraft are viable, these planes could virtually eliminate carbon emissions," said the report by the International Council on Clean Transportation (ICCT).41per cent, more than three times higher than it was in December.

Aircraft manufacturer Airbus has targeted 2035 to bring hydrogen passenger aircraft to the market.41 per cent, more than three times higher than it was in December. – ‘Rich’ data – His team took anonymised data from more than 40,000 mobile phone users, most of which was information from messaging apps and other “interaction” data. It is looking at developing both a single-aisle turbofan jet and a turboprop commuter aircraft. The ICCT said hydrogen storage would reduce the range of such aircraft compared to current ones using conventional fuels, but that nevertheless they could be used to carry up to a third of global air traffic. "There is good news in our data in that infections had been rapidly dropping during January, but they are still extremely high and may have recently stalled at a very high prevalence," said Paul Elliott, director of the Imperial REACT programme. If there were a 100 per cent take up with aircraft using green hydrogen on eligible routes, the ICCT found it would"reduce aviation's carbon emissions by 31 per cent in 2050, representing a capping of emissions at 2035 levels. When further interactions between those primary contacts were included, they could identify 52 percent of people." A take up of 20 per cent to 40 percent would result in a 6 per cent to 12 per cent drop in CO2 emissions. It found prevalence of 2.43per cent, a lower proportion than in the population overall but still"a high level of infection among a highly vulnerable group," the researchers said.

The study estimated that green hydrogen would be cheaper than synthetic fuels that could also provide a means to reduce carbon emissions. The ICCT said carbon taxes would be needed to eliminate the price advantage of jet fuel produced from petroleum. Nearly 65 per cent of people asked reported that they had a confirmed previous infection.” De Montjoye stressed that the intention was not to criticise any individual company or legal regime.
