In this work, we performed a techno-economic analysis for a one-pot, green mechanochemical synthesis of the archetypal metal−organic framework (MOF) UiO-66-NH 2 . The analysis demonstrated that labor costs play a substantial role in the cost of manufacturing. We identified the importance of scaling production from a batch method toward a more continuous synthesis mechanism. Through our work, we were able to mechanochemically produce UiO-66-NH 2 at a rate of 4.52 g per 90 min with a 43% yield for a levelized cost of approximately US $6,498 per kilogram, which is comparable in cost to other archetypal MOFs offered in retail markets.

Conventional adsorbents for CO2 capture typically utilize swings in temperature and/or pressure to adsorb and desorb CO2. These mechanisms can be energy-intensive, which has inspired further research on alternative capture mechanisms such as electro-swing CO2 capture. For this, metal–organic frameworks (MOFs) have been suggested as a potential adsorbent owing to their stability, ultrahigh surface areas, and ability to facilitate redox reactions. However, MOFs have not yet been utilized for the electrochemical capture of CO2. In this work, we demonstrate the facile synthesis of a redox-active MOF-based adsorbent for the electrochemical capture of CO2, and we employ spectroelectrochemistry to understand the adsorbent’s interaction with CO2. This represents an advancement toward the scalable production of electro-swing adsorbents and signals that MOFs can be successfully employed for this process.

Recently, a consortium of companies including Stripe, Alphabet, Shopify, Meta, and McKinsey allocated US$925 million for advanced market commitments to kickstart the early-stage Carbon Dioxide Removal (CDR) market. We argue that it is now more important than ever to consider a Global Cooling Potential (GCP) perspective in corporate CDR procurements. Currently, CDR projects are evaluated and priced on a simple cost-per-tonne basis, which fails to monetize storage duration and can ultimately incentivize the large-scale procurement of short-duration CDR. However, the relative duration of carbon storage is a critical aspect of any CDR project given the implications for climate warming from growing atmospheric concentrations of carbon dioxide. In this perspective article, we apply tonne-year carbon pricing to Microsoft and Stripe's initial CDR procurements to demonstrate that a combination of tonne-year pricing and conventional pricing could produce a CDR portfolio that simultaneously prioritizes storage duration, volume, and temporal urgency, which are all important considerations for maximizing GCP.
