Sustainability, climate change, and green energy.

Thomas Praisner – Freelance Writer

Professional content and technical writing in sustainability, science, and technology



Complex topics, clear writing

Technical content is hard to get right. No matter how important or groundbreaking your message, it’s no use to your readers if they can’t understand it.

As a former researcher and professional writer, I’m uniquely positioned to help. I create polished, well-researched, and engaging content, bringing your message to your audience in a clear, comprehensible package—no matter how complex the topic. 

I write and edit articles, white papers, blog posts, explainers, and technical documents in sustainability, science, and technology. If you’re interested in a scientist-turned-writer who can highlight what really matters about your content, I’d love to hear from you.

How I can help

Whether your goal is to share knowledge, build trust, or demonstrate a product, you need content that’s clear, accurate, and engaging. 

I might be the right fit for you if you need:

  • Complex topics synthesized into clear, engaging content.
  • A writer who can adapt to a specific style and tone for your audience.
  • A writer with a degree in hard science and real-world research experience.
  • The curiosity and attention to detail of a researcher.
  • Professional, polished pieces that showcase your expertise and build trust.
  • A writer who isn’t afraid to ask questions and truly dig into your content.
  • Well-researched, facts-based content with supporting data.
  • An editor for highly technical content.

My services

I offer several types of content and technical writing and editing, including articles, white papers, blog posts, explainers, and technical documents.

I write primarily in the areas of sustainability, science, and technology, working with topics such as: advances in clean/nuclear power and industry, climate change and climate science, chemistry and chemical engineering, catalysis, and other sustainable technologies. 

If you have a job you think is right for me in a different niche or another field of science, don’t hesitate to reach out—I’m always curious to learn about something new.

Here’s a quick overview of the services I’ll provide while we work together:

  • An introduction through call or email (whichever you prefer) to find out if we’re the right fit—free of charge.
  • Understanding your project brief, audience, and key goals.
  • Extensive online research and review, including any sources you provide, to support accurate, in-depth writing.
  • Writing and citing according to your requirements.
  • Two free reasonable revisions to the final piece to ensure it meets your needs.
  • Updates by email at whatever pace you prefer, to keep you informed on progress and show I’ll meet your deadline.
  • Professional, friendly, flexible, and timely cooperation.

I use transparent, fixed-fee pricing based on word count and complexity, so you always know how much you’ll pay.
