Hydrogen

The hydrogen icon represents the chemical element hydrogen, which is a highly flammable and highly reactive gas. It is a key component in various industrial processes and is being explored as a clean energy source.

In software applications, this icon may appear in chemistry or science-related software, educational platforms, or websites focused on renewable energy and sustainability.

From a UX perspective, this icon communicates the idea of a fundamental element in chemistry and a potential clean energy source. It helps users understand the significance of hydrogen in various contexts.

Hydrogen is one of 1,999 icons in Ultimate free icons, made by Streamline and released under CC BY 4.0. It is drawn on a 24 × 24 grid with a 1.5 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds HydrogenIcon to components/icons/streamline-ultimate-hydrogen.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed HydrogenIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Hydrogen icon, or any of 1,999 Ultimate free icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Hydrogen is a line icon drawn with a stroke width of 1.5. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Hydrogen", so screen readers say what it does.

Yes. HydrogenIcon passes every SVG prop to the svg element, so <HydrogenIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with credit: CC BY 4.0 asks you to credit the author (Streamline) where you use the icons. The full terms are in the license, linked on this page.

Yes. CC BY 4.0 asks you to credit the author where you use the icons, for example "Icons by Streamline, CC BY 4.0" on an about or credits page.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are energy, science, environment, chemistry, sustainable and fuel. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Hydrogen in another set.

Ultimate free icons draws many icons in several styles: Bold next to the default. Open the library and pick a style above the grid to see Hydrogen's siblings in it.
