About the Journal
The American Journal of Energy Engineering (AJEE) is a peer-reviewed, open-access journal dedicated to advancing science and practice across renewable and conventional energy systems. Our mission is to publish rigorous research that enables reliable, affordable, and sustainable energy transitions for communities and industries worldwide.
AJEE welcomes original research articles, reviews, short communications, case studies, techno-economic analyses, policy analyses, and replication studies. Interdisciplinary submissions that connect engineering with economics, policy, environmental science, and data analytics are encouraged. Core areas include:
- Solar PV, CSP, and Balance-of-System Design
- Wind, Marine, and Hydro Power Systems
- Geothermal and Thermal Energy Systems
- Bioenergy, Waste-to-Energy, and Biorefinery Integration
- Energy Storage: Batteries, BESS, Hydrogen, and Long-Duration Storage
- Hydrogen Production, Fuel Cells, and Power-to-X
- Carbon Capture, Utilization, and Storage (CCUS)
- Power Electronics, Microgrids, and Grid Integration
- Smart Grids, Demand Response, and Energy Management
- Building Energy Systems, HVAC, and Heat Pumps
- Industrial Energy Efficiency and Electrification
- Combustion, Gas Turbines, and Thermal Cycles
- Energy Systems Modeling, LCA, and Sustainability Metrics
- Energy Economics, Markets, Regulation, and Policy
All manuscripts undergo rigorous double-blind peer review managed by an international editorial board. We support open science practices, including sharing data, models, and code where feasible.
As an open-access journal, AJEE provides immediate, free access to all published content, promoting equitable knowledge sharing and faster innovation.
The journal is published quarterly and is working toward inclusion in leading indexing services to maximise the visibility and impact of authors’ work.
