Orca (carbon Capture Plant)
The Orca carbon capture plant is a facility that uses direct air capture to remove carbon dioxide from the atmosphere. It was constructed by Climeworks and is joint work with Carbfix, an academic-industrial partnership that has developed a novel approach to capture . The plant uses dozens of large fans to pull in air and pass it through a filter. The filter is then released of the it contains through heat. The extracted is later mixed with water and pushed into the ground, using a technology from Carbfix. The plant started sequestering carbon dioxide in 2021. It is said to have cost between $10–15 million to build. It is located in Iceland and is the largest facility of its kind on earth. It is located about 50 kilometers outside Reykjavík next to the Hellisheiði Power Station, which is run by Reykjavík Energy. It was inaugurated on 8 September 2021 in presence of Katrín Jakobsdóttir, the Prime Minister of Iceland. Carbon offsetting potential Climeworks claims that ...

Direct Air Capture
Direct air capture (DAC) is a process of capturing carbon dioxide () directly from the ambient air (as opposed to capturing from point sources, such as a cement factory or biomass power plant) and generating a concentrated stream of for sequestration or utilization or production of carbon-neutral fuel and windgas. Carbon dioxide removal is achieved when ambient air makes contact with chemical media, typically an aqueous alkaline solvent or sorbents. These chemical media are subsequently stripped of CO2 through the application of energy (namely heat), resulting in a CO2 stream that can undergo dehydration and compression, while simultaneously regenerating the chemical media for reuse. DAC was suggested in 1999 by Klaus S. Lackner and is still in development. Several commercial plants are planned or in operation in Europe and the US. Large-scale DAC deployment may be accelerated when connected with economical applications or policy incentives. In contrast to carbon capture a ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Atmosphere
An atmosphere () is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation to produce ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, the solar wind, and cosmic rays to protect organisms from genetic damage. The ...

Climeworks
Climeworks AG is a Swiss company specializing in carbon dioxide air capture technology. The company filters directly from the ambient air through an adsorption-desorption process. Climeworks refers to the filtering of from the ambient air for underground storage as carbon dioxide removal. History Christoph Gebald and Jan Wurzbacher founded Climeworks in November 2009 as a spin-off from ETH Zurich. The two German founders were fellow students in mechanical engineering and had worked with technologies for chemical and physical in the context of their studies and subsequent doctorates. In 2011, Climeworks received capital from investors for the first time to develop a prototype with a modular structure. Since then, rapid scaling has led to their present module technology, which has been available since 2014. In the course of the enterprise's development, a partnership with the automaker Audi succeeded. Further support was provided by the Swiss Federal Office of Energy, which e ...

Sequestering Carbon
Carbon sequestration is the process of storing carbon in a carbon pool. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop land into land for non-crop fast growing plants. Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, enhanced weathering, direct air capture and water capture when combined with storage. Forests, kelp beds, and other forms of plant life absorb carbon dioxide from the air as they grow, and bind it into biomass. However, these biological stores are considered volatile carbon sinks as the long-term sequestration cannot be guaranteed. ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first ...

Reykjavík
Reykjavík ( ; ) is the capital and largest city of Iceland. It is located in southwestern Iceland, on the southern shore of Faxaflói bay. Its latitude is 64°08' N, making it the world's northernmost capital of a sovereign state. With a population of around 131,136 (and 233,034 in the Capital Region), it is the centre of Iceland's cultural, economic, and governmental activity, and is a popular tourist destination. Reykjavík is believed to be the location of the first permanent settlement in Iceland, which, according to Landnámabók, was established by Ingólfr Arnarson in 874 CE. Until the 18th century, there was no urban development in the city location. The city was officially founded in 1786 as a trading town and grew steadily over the following decades, as it transformed into a regional and later national centre of commerce, population, and governmental activities. It is among the cleanest, greenest, and safest cities in the world. History According to legend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
