Techno-Economic Planning of Spatially-Resolved Battery Storage Systems in Renewable-Dominant Grids Under Weather Variability
The ongoing energy transition is significantly increasing the share of renewable energy sources (RES) in power systems; however, their intermittency and variability pose substantial challenges, including load shedding and system congestion. This study examines the role of the battery storage system (BSS) in mitigating these challenges by balancing power supply and demand. We optimize the location, size, and type of batteries using a two-stage stochastic program, with the second stage involving …

From fields to fuel: analyzing the global economic and emissions potential of agricultural pellets, informed by a case study
Agricultural residues represent a vast, underutilized resource for renewable energy. This study combines empirical analysis from 179 countries with a case study of a pelletization facility to evaluate the global potential of agricultural pelletization for fossil fuel replacement. The findings estimate a technical availability of 1.44 billion tons of crop residues suitable for pellet production, translating to a 4.5% potential displacement of global fossil fuel energy use, equating to 22 million…

Clean energy and renewables are not "left" or "woke", they are the best economic choice for the future. While the US denies that, EU is struggling, China charges ahead.

Scaling green hydrogen and CCUS via cement-methanol co-production in China
High costs of green hydrogen and of carbon capture, utilization, and sequestration (CCUS) have hindered policy ambition and slowed real-world deployment, despite their importance for decarbonizing hard-to-abate sectors, including cement and methanol. Given the economic challenges of adopting CCUS in cement and green hydrogen in methanol production separately, we propose a renewable-powered co-production system that couples electrolytic hydrogen and CCUS through molecule exchange. We optimize sy…

Renewables, carbon and the energy crisis
The road towards a viable net-zero world is long and full of obstacles, but all economies need to reduce their carbon footprint.

Coming Wednesday: "Live from @SustainableBrands! It's ‘Living Between Worlds’!”
Join us for this conversation for possibility. https://www.bit.ly/LivingBetweenWorlds

Welcome! You are invited to join a meeting: Living Between Worlds—with Courage, Dignity, and Power. . After registering, you will receive a confirmation email about joining the meeting.
"New worlds don't just happen. We speak them into being…" Please join us for our sixth year of monthly conversations exploring how we might live, with both impact and serenity, in these strange times. If if was in doubt before, it's clear now: We live between old worlds and new—as we move from the fossil age to renewables, from linear take-make-waste economies to circular, from the post-war geo-political-economic order to a world of climate crisis and geopolitical instability—something t…

Grid-informed Sharing Coefficients in Renewable Energy Communities
The role of energy communities in grid operations is highly dependent on the spatial distribution of their participants. In particular, when local energy producers and consumers are concentrated in different feeders, economic incentives from energy communities have the potential to affect local grid congestion. To address this challenge, we propose a feeder-aware allocation strategy that reflects grid topology in energy sharing. This strategy prioritizes energy sharing within the same feeder, t…
