Applied Energy at a glance
Key metrics to place the journal before deciding whether it fits your manuscript and career goals.
What makes this journal worth targeting
- Applied Energy's scope and readership determine whether the journal is a useful target.
- Scope specificity matters more than headline metrics for most manuscript decisions.
- Acceptance rate of ~35-45% means fit determines most outcomes.
When to look elsewhere
- When your paper sits at the edge of the journal's stated scope, borderline fit rarely improves after submission.
- If timeline matters: Applied Energy takes ~1 day to first decision. A faster-turnaround journal may suit a grant or job deadline better.
- If OA is required: gold OA costs $4,210 USD. Check institutional agreements before submitting.
How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: An Applied Energy cover letter should show that the manuscript solves a defined energy-technology problem and that its performance evidence supports a credible deployment path. Lead with the engineering decision the study changes, quantify the result that earns attention, and explain why Applied Energy is the right audience rather than using generic novelty or sustainability language.
Evidence basis: We reviewed the current official Elsevier journal and author guidance on 2026-08-21. Official publisher sources establish the submission requirements below. Manusights judgment translates them into the evidence and positioning decisions an editor can test in a cover letter.

What Applied Energy Editors Screen For
Criterion | What They Want | Common Mistake |
|---|---|---|
Energy technology problem | A specific energy technology and the problem it addresses, named explicitly | Vague references to "energy" or "sustainability" without naming the technology |
Deployment path | Evidence the work can scale, be manufactured, or integrate into a real system | Reporting lab-scale results without acknowledging practical deployment |
Engineering detail | Quantitative performance data (efficiency, cost per kWh, energy density, etc.) | Claiming a "novel approach" without performance numbers |
Journal distinction | Clear reason for Applied Energy vs. Energy (system-level/policy) | Submitting system-level or policy analysis better suited for Energy |
Applied relevance | Technology and engineering focus, not fundamental science with an energy label | Pure science paper that adds energy keywords without applied substance |
What the official sources do and do not tell you
The author guidelines describe scope (energy conversion, storage, distribution, and management) and Elsevier submission procedures. They do not spell out how aggressively editors desk-reject for insufficient applied relevance.
What the editorial model implies:
- the journal wants engineering and technology work, not fundamental science with an energy keyword
- editors screen for a deployment path: can this work scale, be manufactured, or be integrated into a real system?
- performance data is expected alongside mechanistic or modeling results
Turn the scope into a cover-letter test
Applied Energy is a prominent energy journal, but its metric and an unofficial acceptance estimate do not establish fit. The current scope makes these manuscript-level checks more useful:
- A real energy technology problem. The paper must address a specific energy technology: solar cells, batteries, fuel cells, heat pumps, building energy systems, smart grids, hydrogen production, bioenergy, or similar. The cover letter should name the technology and the problem it addresses. Vague references to "energy" or "sustainability" are not enough.
- A path from lab to deployment. This is what distinguishes Applied Energy from fundamental science journals. Editors want to see that the work has practical relevance: can the technology be scaled up? What are the cost implications? How does it compare to existing deployed solutions? Even early-stage research should acknowledge the deployment path.
- Engineering-level detail. Editors expect quantitative performance data: system efficiency, energy density, cost per kWh, levelized cost of energy, coefficient of performance, or whatever metrics apply. A paper that reports a "novel approach" without performance numbers will not survive desk screening.
- Distinction from Energy (Elsevier). Applied Energy wants technology and engineering detail for specific applications. Energy wants system-level analysis with policy or economic context. If your paper is primarily about how a technology fits into the broader energy system (grid planning, policy scenarios, macro-economic impact), Energy may be the better choice. If it is about the technology itself, Applied Energy is correct.
Cover letter template for Applied Energy
Dear Editor,
We submit "the manuscript title" for consideration in Applied Energy.
This paper addresses [ENERGY TECHNOLOGY PROBLEM, e.g., the
rapid capacity fade of lithium-sulfur batteries during cycling,
which limits their practical deployment in electric vehicle
applications].
Using [METHOD, e.g., a carbon-coated separator with controlled
porosity fabricated via electrospinning], we achieve [KEY RESULT
WITH NUMBERS, e.g., a capacity retention of 85% after 500 cycles
at 1C rate, compared to 45% for the unmodified separator, with
a specific energy of 420 Wh/kg at the cell level].
This result is relevant to practical deployment because [DEPLOYMENT
PATH, e.g., the electrospinning process is scalable to roll-to-roll
manufacturing, and the separator material cost adds less than
$2/kWh to the cell cost based on our preliminary techno-economic
analysis].
This manuscript is original and not under consideration elsewhere.
All authors have approved the submission.
Sincerely,
[Corresponding Author Name]

[Email]The deployment relevance paragraph is what sets an Applied Energy cover letter apart from a submission to a fundamental chemistry or materials journal. Don't skip it.
Common mistakes
- Reporting lab-scale results without discussing scalability. If the paper presents a new electrode material tested in coin cells without any discussion of manufacturability, cost, or scaling, the editor will question whether the work is "applied" enough. You don't need a full techno-economic analysis, but acknowledging the scale-up path is expected.
- Writing a cover letter for a fundamental journal. If you can replace "Applied Energy" with "Journal of Physical Chemistry" or "ACS Nano" and the letter still works, the applied dimension isn't clear enough. The letter must reference the energy application, not just the science.
- Not specifying the energy application. "We developed a new catalyst for electrochemical reactions" does not tell the editor whether this is about fuel cells, electrolyzers, CO2 reduction, or batteries. Name the specific application.
- Confusing Applied Energy with Energy. Both are published by Elsevier and have similar citation profiles. The distinction matters: Applied Energy focuses on technology and engineering for specific applications. Energy focuses on system-level analysis with broader policy or economic context. Submitting a system-level modeling paper to Applied Energy (or a device-engineering paper to Energy) increases your desk-rejection risk.
After submission
Applied Energy uses the current Elsevier submission workflow. The sequence is predictable; the timing is not:
- Editorial assessment: Editors evaluate scope, article type, evidence, and fit before deciding whether to invite external review. Timing varies by manuscript.
- Peer review: If invited, external review timing depends on editor and reviewer availability.
- Reviewer expectations: Applied Energy reviewers typically ask for more engineering data, cost analysis, or comparison with existing technologies. Papers that include techno-economic perspectives from the start have smoother review cycles.
- Revision window: Follow the deadline in the decision letter and request an extension when the evidence work genuinely requires it.
- Publication: Follow the production status supplied after acceptance rather than planning around an outside range.
If your paper is desk-rejected, check whether the rejection cites scope mismatch. If so, consider whether Energy, Energy Conversion and Management, or a technology-specific journal would be a better fit.
Five cover-letter risks to remove
Use these five editorial checks before upload. They are Manusights judgment applied to the journal's public scope, not a measured Applied Energy rejection dataset.
Lab-scale results without any discussion of the deployment path. Applied Energy is not a fundamental energy science journal. Its editorial model expects that the work has practical relevance: can the technology scale up? What are the manufacturing or cost implications? How does it compare to currently deployed solutions?
A cover letter that reports coin-cell battery performance, a lab-bench photovoltaic module, or a bench-top heat pump without acknowledging scale-up constraints, cost range, or system integration is missing the journal's central requirement. The deployment path does not need to be fully validated, but it must be explicitly addressed.
Missing engineering performance numbers. Applied Energy reviewers expect quantitative performance data: system efficiency, energy density, specific power, cost per kWh, levelized cost of energy, coefficient of performance, or whichever metrics apply to the specific technology. A cover letter that describes "a novel electrode architecture with improved performance" without the performance numbers is not making a claim the editor can evaluate. The numbers must be in the cover letter, not only in the abstract.
Fundamental science framed as applied energy work. If the cover letter describes a new material, a catalytic mechanism, or a chemical synthesis that has potential energy applications, but the paper itself is a fundamental science study, Applied Energy is not the right venue. The journal covers technology and engineering for specific energy applications. Cover letters that use energy keywords (solar, battery, hydrogen) to frame work that is primarily about physical chemistry, surface science, or chemical kinetics are misrouting the manuscript.
Confusing Applied Energy with Energy (Elsevier). Both journals are published by Elsevier and have similar citation profiles, which creates persistent scope confusion. Applied Energy focuses on technology and engineering for specific energy applications (solar cells, batteries, fuel cells, heat pumps, building energy systems). Energy focuses on system-level analysis with broader policy or economic context (grid planning, macro-economic energy scenarios, policy modeling).
Cover letters that describe a specific device or technology study submitted to Energy, or a system-level modeling paper submitted to Applied Energy, are frequently redirected at triage.
No comparison to currently deployed solutions or competing technologies. Applied Energy reviewers expect the paper to situate its contribution against existing deployed technologies, not just laboratory benchmarks from the recent literature. A cover letter claiming "our lithium-sulfur battery outperforms state-of-the-art lithium-ion" without specifying the comparison metric, the testing conditions, or the comparison to commercial baseline performance is incomplete. The journal's engineering orientation means readers want to know how close the work is to practical parity with deployed solutions.
A Applied Energy cover letter framing check is the fastest way to verify that your framing meets the editorial bar before submission.
Submit Now If / Think Twice If
Submit to Applied Energy if:
- the paper addresses a specific energy technology (solar, batteries, fuel cells, building energy systems, hydrogen, bioenergy, smart grids) with engineering-level detail
- the cover letter includes quantitative performance data and compares to currently deployed or leading alternative technologies
- there is an explicit discussion of the deployment path: scale-up potential, cost range, or system integration context
- the work is engineering and technology-focused, not fundamental science with energy keywords
- the result is distinct from system-level or policy analysis, which belongs in Energy (Elsevier)
Think twice if:
- the paper is primarily fundamental materials science, chemical kinetics, or surface science with energy applications projected but not demonstrated
- performance is reported only from lab-scale coin cells, bench-top modules, or idealized conditions without deployment context
- the paper is about energy system modeling, grid planning, or policy scenarios rather than specific energy technology
- Joule, Nature Energy, or Advanced Energy Materials would be a better fit because the significance is broader or the materials advance is more fundamental
- the comparison baseline is not the current state of commercial or near-commercial deployment

How Applied Energy Compares for Cover Letter Strategy
Feature | Applied Energy | Energy (Elsevier) | Energy Conversion and Management | Joule |
|---|---|---|---|---|
Cover letter emphasis | Engineering performance + deployment path | System-level energy analysis and policy | Energy conversion efficiency and system performance | Fundamental energy science with broad societal relevance |
Best for | Specific energy technology with deployment context | Energy system modeling and policy | Energy conversion and storage devices | High-impact energy science |
Build the deployment-evidence paragraph
Applied Energy's current scope reaches from conversion and conservation to integrated systems, optimization, emissions, and the transition to net zero. That breadth does not mean every energy-adjacent result belongs. The letter should show how the evidence changes a system-level decision.
Sentence job | What to name | What to leave out |
|---|---|---|
System boundary | Technology, operating context, comparator, and scale | A generic promise to “advance sustainability” |
Decisive result | The measured gain and the condition under which it holds | A best-case percentage without its baseline |
Deployment constraint | Cost, reliability, emissions, resource, or integration tradeoff | “Commercial potential” without evidence |
Journal fit | The Applied Energy audience that can use the finding | Prestige, citation rank, or guessed acceptance odds |
For example, “Our controller reduced peak grid imports by 18% in a year-long multi-building simulation while preserving comfort constraints” gives an editor a system, comparator, result, and boundary. “Our innovative AI method improves energy efficiency” does not. If the manuscript cannot support the more specific sentence, narrow the cover-letter claim before polishing it.
The editorial policy states the practical boundary clearly: the energy contribution must be visible in the system context, not inferred from a generic sustainability label.
Evidence basis: This cover-letter screen was checked against Applied Energy's current author guidance and scope page. The deployment-evidence map is Manusights editorial synthesis and cannot predict an editorial outcome.
Final letter audit
Use one sentence for each of these six jobs: the energy-system problem, the intervention or model, the fair comparator, the result under realistic conditions, the deployment consequence, and the most important boundary. Then verify that the manuscript contains the evidence each sentence points to. Mandatory statements about originality, exclusive submission, author approval, conflicts, funding, data, and related work must agree with the portal and manuscript rather than appearing as boilerplate.
A useful opener is: “We show that [intervention] changes [system outcome] relative to [benchmark] under [operating condition], with [validation] supporting the result and [boundary] limiting its present use.” If the bracketed claims cannot be filled without adjectives such as novel, significant, or transformative, the evidence chain needs work before the letter does.
