More than 40 per cent of the biogas generated in the country is used to run vehicles. A business delegation from Sweden was also in the city for the project.It is learnt that the Keshopur sewage treatment plant has been selected for the project because it is located close to a CNG-filling station and a CNG-fuelled power grid A senior officer said that the Delhi government was also exploring possibility to use biogas to run DTC buses in the national capital. The compressed biogas is almost similar to CNG, the main constituent of which is methane. Swedish ambassador Harald Sandberg, who recently met Delhi chief minister Arvind Kejriwal, has reportedly offered a technology to convert biogas into CNG through sewage treatment plants. Sweden is considered a pioneer in biogas technology for heating, power generation and fuelling vehicles.The official said the plant will receive raw gas emitted by the sewage treatment plant and upgrade it so that it can be used to propel vehicles. The Delhi Jal Board is currently renovating it to make it fully functional as part of the Yamuna Action Plan.
Thus it can be directly injected into CNG cylinders for vehicular use or fed into CNG-fuelled power grid. At full capacity, the plant will emit enough raw gas for the biogas plant to generate around 25,000 cubic metres of compressed biogas per day. This is enough to fuel 120 buses. The sewage treatment plant, functioning partially at present, can treat 72 million litres of waste water per day. It can be mixed with CNG and used. The project, once completed, will earn the capital city the distinction of having the country’s first public transport fleet that will run on two types of clean fuel — biogas and CNG. The project, a first for the city, will see biogas generated at sewage treatment China Heating Mat plants being converted into CNG.Sweden has developed the technology that converts biogas into CNG to run public transport system.The AAP government is exploring the possibility with the Swedish government to convert biogas into CNG.City transport minister Gopal Rai and PWD minister Satyendra Jain had recently visited Sweden to study its transportation system.
About four billion years ago Earth, Venus and Mars may have all been habitable. The research was published in the journal Astrobiology. "Most early planetary environments are unstable," he said. "The Universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens," said Dr Aditya Chopra from the Australian National University Research Sch-ool of Earth Sciences. "One intriguing prediction of the Gaian Bottleneck model is that the vast majority of fossils in the universe will be from extinct microbial life, not from multicellular species such as dinosaurs or humanoids that take billions of years to evolve," said Lineweaver.
In research aiming to understand how life might develop, the scientists realised new life would commonly die out due to runaway heating or cooling on their fledgling planets. A plausible solution to Fermi’s paradox, say the researchers, is near universal early extinction, which they have named the Gaian Bottleneck. "Early life is fragile, so we believe it rarely evolves quickly enough to survive," said Chopra. "The mystery of why we haven’t yet found signs of aliens may have less to heating film Manufacturers do with the likelihood of the origin of life and have more to do with the rarity of the rapid emergence of biological regulation of feedback cycles on planetary surfaces," said associate Professor Charley Lineweaver.The mystery of why we have not found signs of aliens yet may have been solved by scientists, including one of Ind-ian-origin, who suggest life on other planets wou-ld likely be brief and become extinct very quickly.
