Applied Energy Response to Reviewers: Rebuttal That Wins (2026)

Applied Energy's reviewer pool is the white space here, and it is worth being precise about. The associate editor who handles your paper draws reviewers from energy-systems modeling, techno-economic analysis, and applied energy engineering. Two practical consequences follow for your response to reviewers.

First, sensitivity and uncertainty analysis is treated as a publication requirement for any modeling paper, not a nicety. Reviewers from the energy-economics side of the pool routinely flag papers that project hydrogen cost, solar LCOE, or storage economics from a single price trajectory. If your headline conclusion changes when one input moves by 20 percent, the reviewer reads the paper as unvalidated, and the rebuttal has to show the sensitivity sweep rather than argue the point assumption was reasonable.

Second, novelty at Applied Energy is system-level novelty. A reviewer who survived the 3-day desk filter and still questions novelty is usually telling you the contribution reads as incremental modeling or a component result, not a systems insight. The associate editor weighs reviewer consensus, and on this point you cannot win with assertion.

You answer it by reframing the contribution around what changes at system scale: a capacity factor, a round-trip efficiency, an LCOE under realistic operating conditions. This is methodological rigor applied to the contribution claim itself, and it is the most common reason an otherwise sound Applied Energy paper goes a second round.

Use a self-contained document so the editor and reviewers never have to dig back through the original manuscript. Open with one short paragraph that thanks the editor and reviewers, summarizes the major changes, and states your page/line convention. Then handle each reviewer in order, quoting every comment in full before your reply.

Here is a copyable template. Replace the bracketed fields with your own content.

Dear Editor,

Thank you for the opportunity to revise our manuscript [MS ID] for
Applied Energy. We are grateful to both reviewers for their detailed
and constructive comments. We have revised the manuscript accordingly,
and all page and line numbers below refer to the CLEAN REVISED version.

Summary of major changes:
1. We added a system-integration section (page 9, lines 210 to 248)
   and a global sensitivity analysis (Figure 6, page 14).
2. We sourced every cost assumption to a 2025 commercial database
   with access dates (Table 2, page 7).

------------------------------------------------------------
Reviewer 1

Comment 1.1: "The cost-competitiveness conclusion is not robust to the
input price assumptions."

Author response: We agree. We revised the analysis to include a global
sensitivity sweep across the plausible range of each cost input. The
conclusion holds across the full range; the result is shown in Figure 6
(page 14) and described on page 14, lines 305 to 322.

Comment 1.2: "Novelty over prior system models is unclear."

Author response: Thank you for raising this. We clarified that the
contribution is the system-level coupling, not the component model. We
revised the abstract (page 1, lines 18 to 27) and added a contribution
paragraph (page 3, lines 58 to 71) reporting the change in round-trip
efficiency at system scale.

------------------------------------------------------------
Reviewer 2

Comment 2.1: "The validation against measured data is thin."

Author response: We expanded the validation in Section 3.2 (page 11,
lines 255 to 280) and added a comparison table (Table 4, page 12).

Notice the structure: a salutation, a numbered change summary, each comment quoted, and every response ending in a page and line reference. That is the shape Applied Energy reviewers expect, and it maps directly onto Elsevier Editorial Manager's response-to-reviewers upload field.

Make it impossible to confuse a reviewer comment with your reply. Set every reviewer comment in bold (or a distinct color) and label your reply with a plain "Author response:" lead-in. This is rule six of the PLOS Ten Simple Rules, and Nature Computational Science makes the same point in its 2025 editorial on responding to reviewers: a navigable, self-contained response document is what keeps editors and reviewers efficient.

It matters more at Applied Energy than at many journals because the reviewers are reading several technical rebuttals at once and will not hunt for your answer. A reviewer who has to differentiate your response from their own comment line by line is a reviewer who is already irritated before they evaluate the science.

The fastest way to turn a major revision into a rejection on revision is tone. Applied Energy reviewers are domain experts who will read a defensive reply as a refusal to do the work. Calibrate every response toward evidence, not argument.

Read your finished letter once as if you were the reviewer. If a reply would make you, the reviewer, feel dismissed or unconvinced, rewrite it before you submit. If you want a second read on tone and completeness, run a manuscript and rebuttal readiness check before you upload.

This guide was last reviewed on June 6, 2026. The table below is about the rebuttal work you control, not the journal's review pipeline. For the journal-side decision timeline, see the Applied Energy review time guide; here the focus is how much author effort each part of the response demands.

In our pre-submission review work with Applied Energy submissions, the rebuttals that fail are rarely impolite and rarely lazy. They fail because they answer the reviewer with words where the reviewer asked for evidence. Three named patterns account for most of the rejection-on-revision outcomes we see, and each maps to a specific manuscript component you can fix before you resubmit your response.

Prose where a sensitivity analysis was requested. This is the single most common Applied Energy rebuttal failure we review. A reviewer flags that the cost or efficiency conclusion is not robust to input assumptions, and the response defends the original point estimate as "standard" or "widely used" instead of running the sweep.

Across our Applied Energy pre-submission reviews, manuscripts whose conclusion flips when a single cost input moves by 20 percent are treated as unvalidated by the energy-economics reviewers no matter how the rebuttal is worded. The fix is concrete: add a global sensitivity analysis figure, report the bounds for each input, and rewrite the response to point at the new figure and its page and line, not at the reasonableness of the assumption.

A novelty rebuttal that re-asserts instead of reframing. When an Applied Energy reviewer questions novelty after the desk filter, they are usually saying the contribution reads as incremental modeling or a component result. The losing response repeats the original novelty sentence in stronger language. The winning response reframes the contribution at system scale and edits the abstract and a contribution paragraph to show it.

In our Applied Energy reviews, the manuscripts that clear this comment are the ones where the response letter points to a revised abstract reporting a system-level metric (round-trip efficiency, capacity factor, or system LCOE), not to an unchanged claim defended more loudly.

Page and line numbers that do not match the file the reviewer is reading. A surprising share of the failed Applied Energy rebuttals we see do everything right except locate the changes. The author cites original-version line numbers while the reviewer opens the clean revised version, every reference is off by a page, and the reviewer cannot confirm a single change.

We treat this as a manuscript-and-letter integrity check: state the convention once, regenerate every page and line reference against the final clean file, and verify each one before submission. It is the cheapest possible fix and it prevents an entire avoidable round.

Check whether your Applied Energy rebuttal answers every comment with evidence before you upload it to Editorial Manager.

A major revision is not a soft acceptance. Applied Energy reviewers can and do recommend rejection at the second round, and the journal's editorial process gives the associate editor latitude to follow reviewer consensus. Most of the rejection-on-revision outcomes we review trace to the same root: the rebuttal argued with the reviewer rather than running the requested validation or sensitivity work. A defensive letter on a paper whose core robustness was never demonstrated almost always reproduces the original criticism in stronger terms.

Be honest with yourself before you resubmit. If the underlying issue is that the conclusion is not robust, or that the contribution is genuinely component-level rather than system-level, a polished rebuttal will not save it, and you may be better served by a scope redirect. The rejected from Applied Energy guide covers where conversion-engineering and component work tends to land next.

The rebuttal is the right tool only when the science can actually clear the bar; when it cannot, the most expensive mistake is spending a 6-to-12-week round to find that out.

• Every reviewer comment is quoted in full and answered, with no point skipped.
• Each claimed change cites an exact page and line in the clean revised manuscript, and the convention is stated once at the top.
• Every "more validation" or "robustness" comment is answered with a new figure, table, or sensitivity sweep, not prose.
• The tone is evidence-led throughout, defensive only where you have data to defend with.
• A co-author has independently confirmed that every page and line reference resolves correctly.
