The cost is estimated at $10–50/tCO 2 with a mid-point price of $30/tCO 2. After 30 years of operation, such a Wood Vault facility would have sequestered 30 MtCO 2, stored in 300 WVUs, occupying a land surface of 300 ha. A 1 MtCO 2 y −1 sequestration rate can be achieved by collecting currently unused wood residuals (WR) on an area of 25,000 km 2, the size of 10 typical counties in the eastern US, corresponding to an average transportation distance of less than 100 km. A prototype Wood Vault Unit (WVU) occupies 1 hectare (ha, 100 m by 100 m) of surface land, 20 m tall, stores up to 100,000 m 3 of wood, sequestering 0.1 MtCO 2. Smaller sizes are also possible, named Baby Vault. Storing wood in many environments is possible, leading to seven versions of Wood Vault: (1) Burial Mound (Tumulus or Barrow), (2) Underground (Pit, Quarry, or Mine), (3) Super Vault, (4) Shelter, (5) AquaOpen or AquaVault with wood submerged under water, (6) DesertOpen or DesertVault in dry regions, (7) FreezeVault in cold regions such as Antarctica. The buried wood enters a quasi-geological reservoir that is expected to stay intact semi-permanently. We describe a method of constructing a wood storage facility, named Wood Vault, that can bury woody biomass on a mega-tonne scale in specially engineered enclosures to ensure anaerobic environments, thus preventing wood decay. This study aims to develop a concrete way to carry out WHS at large-scale. To date, the technology has only been purposefully tested in small-scale demonstration projects. Governments, industries, and individuals must collaborate to create a supportive policy environment that encourages the adoption of carbon sequestration practices on a larger scale.ĭon’t miss out on ET Prime stories! Get your daily dose of business updates on WhatsApp.Wood harvesting and storage (WHS) is a hybrid Nature-Engineering combination method to combat climate change by harvesting wood sustainably and storing it semi-permanently for carbon sequestration. Looking ahead, further research and innovation are needed to refine existing techniques and develop new ones. Ensuring the long-term stability of stored carbon, developing cost-effective technologies, and managing potential ecological impacts are among the hurdles that need to be addressed. While carbon sequestration shows immense promise, it's not without its challenges. Techniques like direct air capture, where CO2 is extracted directly from the air using special technology, and carbon capture and storage (CCS), where CO2 emissions from industrial processes are captured before they are released into the atmosphere, are examples of artificial sequestration. Forests, wetlands, and oceans are natural carbon sinks, where CO2 is absorbed and stored over time.Īrtificial Sequ estration: Artificial carbon sequestration involves human-driven methods to capture and store CO2. Natural Sequestration: Natural carbon sequestration occurs through various ecosystems and processes, such as photosynthesis in plants, which captures CO2 and converts it into organic matter. Artificial Sequestration: There are two primary types of carbon sequestration: natural and artificial. Businesses that set the bar high for sustainability frequently gain a competitive edge, luring more clients and securing enduring loyalty. By adopting carbon sequestration, businesses can better meet the needs of consumers, who are shifting their buying habits to favor eco-friendly brands. The companies and business can successfully link their financial interests with environmental stewardship and promote a more sustainable future by incorporating these techniques into their operations.Īlthough it is said that putting carbon sequestration strategies into action has large expenses, but the advantages surpass the initial investments by a wide margin. ![]() They can actively contribute to carbon sequestration in a variety of ways like - the use of renewable energy sources, increased energy efficiency, reforestation programs, and investment in carbon capture systems. ![]() The crucial part that corporations can play in carbon sequestration efforts and can adopt sustainable practices and engage as change agents in the climate issue rather than being apathetic spectators.
