How energy and chemistry converge for a fossil-free future Open
The chemical industry must undergo a dual transformation: electrifying energy use and defossilizing carbon feedstocks. This paper, developed by ENGIEs Scientific Council, examines how energy and chemistry can converge to enable this shift.…

Estimating the climate impacts of hydrogen emissions in a net-zero US economy Open
Hydrogen is not a greenhouse gas, but its interactions with other species in the atmosphere indirectly induce radiative forcing. This study evaluates the relative impacts of hydrogen emissions across 23 different net-zero scenarios from fi…

Modeling Climate Impacts of Hydrogen Transition Pathways Open
Hydrogen has emerged as a key contender for decarbonizing hard-to-abate sectors, as it has the advantage of emitting no direct carbon dioxide emissions during combustion. However, modeled indirect climate warming impacts from additional hy…

Effect of hydrogen leakage on the life cycle climate impacts of hydrogen supply chains Open
Hydrogen is of interest for decarbonizing hard-to-abate sectors because it does not produce carbon dioxide when combusted. However, hydrogen has indirect warming effects. Here we conducted a life cycle assessment of electrolysis and steam …

Evaluating carbon removal: Integrating technical potential with environmental, social, governance criteria, and sequestration permanence Open
Climate modeling suggests that achieving international climate goals requires a reduction in current CO2 emissions by over 90%, with any remaining emissions to be addressed through carbon dioxide removal (CDR) solutions. Sixteen CDR strate…

Effect of Hydrogen Leakage on the Life Cycle Climate Impacts of Hydrogen Supply Chains Open
Hydrogen is of interest for decarbonizing hard-to-abate sectors because it does not produce carbon dioxide when combusted. However, hydrogen has indirect warming effects. In this work, we conducted a life cycle assessment of electrolysis a…

Circularity: Understanding the Environmental Tradeoffs of Additive Manufacturing with Waste Plastics Open
This paper examines the emissions tradeoffs of additive manufacturing (i.e., 3D printing) using plastic waste in fused granular fabrication (FGF) versus traditional fused filament fabrication (FFF) and injection molding (IM). A ‘cradle-to-…

A Review of Resilience and Long-Term Planning in Power and Water Systems in the United States Open
There is recognition among power and water utilities that the frequency and magnitude of high consequence and low probability events could increase as a result of climate change. The interconnected nature of energy-water systems raises the…

Assessing the Potential for Building Sector Retrofits to Mitigate ERCOT Electricity Shortfalls During Winter Storm Uri Open
This analysis investigates energy performance of the residential and commercial building sectors in the Electric Reliability Council of Texas (ERCOT) during Winter Storm Uri. ERCOT electricity demand was modeled for the ERCOT baseline buil…

Texas Can Go Big to Reach Net Zero Open
While Texas political leaders openly dismiss and mock the risks of climate change and suspiciously eye policymakers in other states or countries who seek to reduce emissions, Texas industry, consumers, and cities are decarbonizing and doin…

Model to inform the expansion of hydrogen distribution infrastructure Open
A growing hydrogen economy requires new hydrogen distribution infrastructure to link geographically distributed hubs of supply and demand. The Hydrogen Optimization with Deployment of Infrastructure (HOwDI) Model helps meet this requiremen…

Observations of peak electric load growth in ERCOT with the rise of electrified heating and its implications for future resource planning Open
This analysis quantitatively compares the evolution in summer and winter peak demands in the Electric Reliability Council of Texas (ERCOT) service area from 1997 through 2021. Weather data for the days in which peak demand occurred were al…
