Bi Chart, a charcoal material derived from plant biomass, has long been welcomed as a promising tool for removing carbon dioxide. However, new research by researchers at Stanford University emphasizes serious problems. The current method for evaluating the potential of carbon storage of bi -charcoal may significantly underestimate its true environmental advantages.

This paper, published in the environmental survey letter, indicates a way to evaluate bio -charcoal more accurately and to enhance the reliability as a climate change solution.

This study has challenged traditional durability metrics and proposes a more subtle framework to evaluate the violin project. It has grown from an early project that is considering the soil ability to capture carbon dioxide.

“Biacha is a very important factor in the carbon removal market, but I have noticed that there is almost no useful data about how it actually behaves,” said Stanford Doller School Professor of Earth System Science. One Kate Maher said. Sustainability of Stanford Woods Institute for the ENVIRONMENT and advanced fellow. “It is important for policy proppons and buyers to recognize this.”

Review the durability of the bias

Biacha is a charcoal -like result of burning organic matter slowly with little oxygen. Its charm is the ability to store carbon in the soil for a long time, hindering that the atmosphere will not enter as a greenhouse gas again. The durability of bio -charcoal (resistance to decomposition) is an important factor in determining its effectiveness.

However, most bioacer durability ratio depends on a single metric, the ratio of hydrogen and carbon. This simple scale is considered to be correlated with the stability of the biacha in the soil, but Stanford’s research has revealed that this approach could be too reduced.

By re -analyzing the existing largest bioacer durability dataset, researchers only depend on the ratio of hydrogen and carbon, and important factors such as soil type, environmental conditions, and fluctuations in bi -charcoal raw materials. I revealed that I would ignore it. Without these factors, the model often cannot predict the real world of carbon storage, soil health and the interests of crops.

“Biacha is a major possibility of carbon dioxide removal, but it is considered low in the market until the long -term durability can be established with confidence and predicted.” “To reach a place to compete with very durable solutions such as direct air capture, it moves beyond one size metrics and develops more useful datasets. I need to do.

The survey also found that the current standard could underestimate the possibility of carbon storage in many biacher projects. In many cases, laboratory experiments, which are the basis of durability evaluation, are easier to handle, but in many cases, actual conditions cannot be accurately duplicated. For example, outdoor research indicates that factors such as soil composition and regional climate may dramatically affect how biocharcoal, which has once developed, operates.

Underestimating the durability of Biochar may not be a considerable amount of carbon storage. This can lead to economic and policy issues as the demand for carbon offset increases.

Toward a wiser future

In order to deal with these drawbacks, researchers propose a two -step evaluation process. Preliminary estimation of the potential of biocher that removes carbon dioxide before deployment, and then the field measurement that improves these estimated values ​​for a long time. They argue that this approach can unlock additional project value, improve predictive modeling data, and enhance the reliability of biacros in the carbon market.

In addition, this study emphasizes the need for a adjusted global field trial to better understand how environment variables affect the performance of biochart. These examinations will notify you of new durability standards explaining the actual fluctuation and open the path to more accurate carbon credits.

“Unlike most of the market technology, the biocher is directed to the shovel and offers today’s carbon removal,” said Ringsby. “In order to maximize the possibilities, you need better data and stronger standards, and you need to cooperate as a community to design appropriate experiments.”
