What are the alternative fuels
Global warming is increasing day by day. Global warming can significantly damage the Earth’s atmosphere. Snow is melting rapidly in the polar regions, and sea levels are rising. The oceans are becoming acidic. Climate change is nothing new. Has happened many times in the past. It all happened slowly for natural reasons. But current Climate change is not like that. Goes very fast. All of these are man-made greenhouse gases It happens with emissions.
Are important in greenhouse gas emissions
The most important greenhouse gas emissions are carbon dioxide and methane. Most of these emissions are fossil Are generated by the burning of fuels. So scientists are moving toward clean fuels, and Engineers are focused. Are creating many innovative innovations.
Carbon extraction from air(alternative fuels)
The extraction of carbon from the air is an innovative invention. For the last two centuries, we have We are releasing carbon dioxide into the atmosphere. So much so that it stopped the use of fossil fuels Not a rapid decline. Hence the need to remove carbon dioxide from the air Is.
Therefore, some technologies can beat carbon dioxide directly from the air. But not all Costly. That’s why Columbia University researchers say carbon dioxide is emitted from the air By reusing the technology of capturing -supply to generate electricity and store carbon Focused on cost reduction.
Example of carbon extraction from air
Install wind turbines on mountains that are submerged in the ocean and make wind power with them In addition, doing so is an attempt to drive away carbon. Extracts carbon from the air The largest center was established in Iceland last year. It works with the help of geothermal electricity. Connected to volcanoes underground. It is hardened by chemical reactions to carbonate Will change. Wind power plants generate more electricity compared to geothermal power plants Produce.
So with this technology wind power plants that are set up in the ocean near the coast Are expected to connect. This will cheaply absorb carbon from the air Is possible. Good for the environment. IIT Guwahati, and NTPC jointly power plants in India Decided to set up a factory to extract carbon dioxide from.
Home electricity with electric vehicles(alternative fuels)
Do electric vehicles (EVs) run on batteries? Also, these are electric vehicles that come with the technology of charging our home electricity needs from vehicle to home. Electric vehicles with large batteries are not only charged but also from charged batteries
They also supply electricity to the house. That is, they are useful in two ways. On the one hand Charging on the other hand provides electricity. Similar technology is currently available in some vehicles. But this situation is changing rapidly.
Example
Ford Company New F-150 Lightning Track Example. It averages three per house with a single charge Can supply enough electricity for days. Sedan types like Tesla Model S, and Nissan Leaf Electric vehicles can store 80-100 kilowatt-hours of electricity. One kilowatt-hour of electricity is enough to keep a typical refrigerator running for five hours. This means that an electric vehicle battery will last for two to three days in a home and Can supply electricity.
That’s why some people in America now use EVs for peak shaving. That is Home electricity is used for battery charging without relying on daytime grids. Taking power from EV batteries only when power demand is high Saving money.
Lithium production with geothermal electricity(alternative fuels)
It would be a good idea to look at greenhouse gas emissions as renewable energy. But it’s only if we use renewable energy in everything from vehicles to buildings Is possible. The role of batteries is crucial. But the shortage of batteries is hampering it. Like electric vehicles, Most of them use lithium-ion batteries. Hence to meet the lithium shortage American geologists and engineers are focusing on geothermal power plants.
The hot salt water remains in the earth’s interior to generate electricity based on heat. Due to the high percentage of salt, it is sent back underground. In which salt Not only that but also lithium. The Salton Sea undertook to recover it. If these are successful getting large amounts of lithium Extraction is expected to be permanent.
Recently, MIT researchers developed a new type of thermophotovoltaic (TPV) cell. They generate electricity from heat and operate at 40 percent higher efficiency. Currently, available TPV cells emit a temperature of 1900-2400 degrees Celsius Make electricity from materials. These can be mounted to grids such as thermal batteries.
Dissolve salt and electricity
It is well known that coal is used to make electricity. But even with salt, you get electricity that Can be made. It’s going to be amazing to hear. Centralized solar power Makes this possible. The key is to concentrate the sunlight through the mirrors.
The heat generated when sunlight is concentrated is applied to the salt. At high temperatures, The salt melts. The steam generated from this is used to generate electricity back to the power generators. Do it Can be used anywhere if stored in batteries. It is a pure fuel that is quite expensive Scientists hope that it will be very useful.
Scientists are focused on further improving this. Currently, centralized solar power The salts used are not as stable at high temperatures. So with hot sand Experiments are being conducted. When the hot materials are stored and cloudy, electricity at night
Attempts were made to make.
Solar canals(alternative fuels)
Power generation on the one hand and water-saving on the other. Solar panels in two ways How will it be if utilized? The idea is to install solar panels over time Led to the design. Now gaining momentum around the world. But it was launched in India in 2012. As part of the Canal Solar Power Project in Gujarat, 331 km of solar panels were installed on the Narmada river canals. By which one
The goal is to generate megawatts of electricity.
Apart from that, it sees 90 lakh liters of water evaporating annually. Solar panels on canals Another benefit of setting up is the increase in power generation. The presence of cold water underneath This causes the plate temperature to drop to about 5.5 degrees Celsius.
This increases the power generation capacity. These are being implemented in another 8 states. It is noteworthy that the solar canal system is currently being developed in California, USA. Total To save 6,500 crore gallons of water by installing these over 4000 miles of canals Is expected. This is to meet the water needs of 50,000 acres of crop fields or 20 lakh people Can meet.
