原文摘要

This paper describes a technology (biochar sequestration) that can meet the challenges of global climate change by reducing greenhouse gas emission from fossil fuels. When combined with bionergy production, this biochar sequestration is a clean energy technology that reduces emissions as well as sequesters carbon. It also locks up rapidly decomposing carbon in plant biomass in a much more durable form. The various advantages of this technology in terms of storage capacity, emission reduction, pollution control, and ease of monitoring are discussed. In addition, biochar sequestration does not require a fundamental scientific advance and the underlying technology is robust and simple. It does, however, require studies to optimize biochar properties and to evaluate the economic costs and benefits of large-scale deployment.

原文摘要簡述

本文介紹了一種技術(生物炭固存),它可以通過減少化石燃料產生的溫室氣體排放來應對全球氣候變遷的挑戰。當與仿生能源生產結合使用時,這種生物炭固存是一種乾淨的能源技術,可以減少排放並固存碳。它還以更持久的形式鎖住植物生物質中快速分解的碳。此技術中的各種好處就存儲容量、減排、污染控制和易於監控方面予以討論。另外,生物炭固存不需要基本科學的進步,其基礎技術既堅固又簡單。但是,它確實需要進行研究以優化生物炭的性能,並評估大規模部署的經濟成本和收益。
