加速吸附劑碳捕獲的整體平臺 ▲ 作者：Charithea Charalambous, Elias Moubarak, Johannes Schilling, Eva Sanchez Fernandez, Jin-Yu Wang, Laura Herraiz, Fergus Mcilwaine, Shing Bo Peh, Matthew Garvin, Kevin Maik Jablonka, Seyed Mohamad Moosavi, Joren Van Herck, Aysu Yurdusen Ozturk, Alireza Pourghaderi, Ah-Young Song, Georges Mouchaham, Christian Serre, Jeffrey A. Reimer, André Bardow, Berend Smit & Susana Garcia ▲鏈接： https://www.nature.com/articles/s41586-024-07683-8 ▲摘要： 減少二氧化碳(CO2)排放迫切需要大規(guī)模部署碳捕獲技術(shù)。這些技術(shù)必須從不同的來源分離二氧化碳，并將其輸送到不同的匯。尋求特定源匯對的最佳解決方案是一項(xiàng)復(fù)雜的、涉及多個利益攸關(guān)方的多目標(biāo)挑戰(zhàn)，并取決于社會、經(jīng)濟(jì)和區(qū)域背景。 目前，研究遵循一個順序的方法:化學(xué)家專注于材料設(shè)計(jì)，工程師專注于優(yōu)化工藝，然后在影響經(jīng)濟(jì)和環(huán)境的規(guī)模上進(jìn)行操作。評估這些影響，比如電廠生命周期內(nèi)的溫室氣體排放，通常是最后的步驟之一。 研究者介紹了定制吸收材料的工藝信息設(shè)計(jì)（PrISMa）平臺，集成了材料、工藝設(shè)計(jì)、技術(shù)經(jīng)濟(jì)和生命周期評估。他們比較了全球5個地區(qū)使用不同技術(shù)從不同來源捕獲二氧化碳的60多個案例研究。 該平臺同時向各利益相關(guān)者通報技術(shù)的成本效益、工藝配置和位置，揭示高性能吸附劑的分子特征，并提供有關(guān)環(huán)境影響、協(xié)同效益和權(quán)衡的見解。通過在早期研究階段聯(lián)合利益相關(guān)者，PrISMa有助于加速碳捕集技術(shù)的發(fā)展，推動實(shí)現(xiàn)凈零排放的世界。 ▲ Abstract： Reducing carbon dioxide (CO2) emissions urgently requires the large-scale deployment of carbon-capture technologies. These technologies must separate CO2 from various sources and deliver it to different sinks. The quest for optimal solutions for specific source–sink pairs is a complex, multi-objective challenge involving multiple stakeholders and depends on social, economic and regional contexts. Currently, research follows a sequential approach: chemists focus on materials design and engineers on optimizing processes, which are then operated at a scale that impacts the economy and the environment. Assessing these impacts, such as the greenhouse gas emissions over the plant’s lifetime, is typically one of the final steps. Here we introduce the PrISMa (Process-Informed design of tailor-made Sorbent Materials) platform, which integrates materials, process design, techno-economics and life-cycle assessment. We compare more than 60 case studies capturing CO2 from various sources in 5 global regions using different technologies. The platform simultaneously informs various stakeholders about the cost-effectiveness of technologies, process configurations and locations, reveals the molecular characteristics of the top-performing sorbents, and provides insights on environmental impacts, co-benefits and trade-offs. By uniting stakeholders at an early research stage, PrISMa accelerates carbon-capture technology development during this critical period as we aim for a net-zero world. |
