Abstract The European ammonia industry emits 36 million tons of carbon dioxide annually, primarily from steam methane reforming (SMR) hydrogen production. These emissions can be mitigated by producing via water electrolysis using dedicated renewables with grid backup. This study investigates the impact decarbonization targets for synthesis on economic viability and technical feasibility retrofitting existing plants on-site, semi-islanded electrolytic Results show that cuts emissions,...
Urban planners face challenges in water infrastructure development decisions due to short-term variation availability and demand, long-term uncertainty climate population growth, differing perspectives on the value of water. This paper classifies these multiple uncertainties develops a decision framework that combines simulation for probabilistic uncertainty, scenario analysis deep multistage reduced over time with additional information. is applied case from Melbourne, Australia, where...
Allocating cloud computing greenhouse gas (GHG) emissions is essential for distributing responsibility climate damages and informing strategies to reduce data center energy consumption Scope 2 emissions. However, few studies investigated the practical usability of common GHG accounting frameworks estimating at national level. This study characterizes four sources inaccuracies in cloud-related proposes three targeted interventions address risks. work identifies estimation risks Scopes 3 when...
Evaluating technology options to mitigate the climate impacts of road transportation can be challenging, particularly when they involve a tradeoff between long-lived emissions (e.g., carbon dioxide) and short-lived methane or black carbon). Here we present trends in short- for light- heavy-duty transport globally U.S., EU, China over period 2000-2030, discuss past future changes vehicle technologies reduce these emissions. We model tradeoffs emission reductions across range options, life...
Abstract Reducing carbon dioxide (CO 2 ) emissions through a reliance on natural gas can create hidden commitment to methane (CH 4 leakage mitigation. While the quantity of CH from has been studied extensively, magnitude and timing mitigation required meet climate policy goals is less well understood. Here we address this topic by examining case US electricity under range baseline rate estimates equivalency metrics for converting CO -equivalent emissions. We find that power sector would need...
Abstract Growing momentum for decentralized climate policy and the falling costs of low‐carbon technologies are creating new change mitigation opportunities subnational actors. Here we discuss how research can best support these efforts to allow limited resources stretch further. To stimulate this discussion, identify four priorities. (1) Innovation mechanisms examines local technology improvement achieve high returns on investments. (2) Co‐benefits analyzes non‐climate benefits emissions...
Linkages between the Sustainable Development Goals (SDGs) have sparked research interest because a better understanding of SDG co-benefits may enable faster progress on multiple sustainability fronts. However, linkages are typically analyzed without considering technologies used to implement primary SDG, which secondary effects other SDGs. Here, we outline an approach study this problem by connecting industries and services required produce technology United Nations indicator framework,...
Technology and infrastructure investments targeting a primary sustainable development goal (SDG) can impact other SDGs. Understanding how linkages are shaped by technology characteristics is vital to design efforts that deliberately leverage co-benefits mitigate SDG trade-offs. Here, we present protocol conceptualize identify technology-induced linkages. We describe steps for selecting disaggregating technologies into SDG-relevant categories, conceptualizing linkages, defining scope...
Ammonia production contributes 1% of global carbon emissions due to energy-intensive hydrogen synthesis.To mitigate this, renewable-powered water electrolysis is a promising solution.While numerous studies have explored the use storage and grid backup align renewable energy sources with continuous operation HB process, recent industry efforts focused on increasing plant flexibility, adjusting intermittent power inputs.In this study, we model optimize two configurationscontinuous flexible.The...
Innovations improve technology costs through a diversity of engineering advancements, including changes to materials choices and device or process designs. Understanding how these innovations relate cost change can reveal aspects the evolution, yet developing such understanding is often not possible with strictly quantitative approach due data limitations. In this paper we develop hybrid quantitative-qualitative framework for relating specific by using variables in model as an organizing...
