H2Pro

H2Pro is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand H2Pro rather than just read about it. In short: H2Pro is an Israeli company that develops electrolyzer systems for the production of green hydrogen. The company was co-founded in 2019 by Technion professors Gideon Grader and Avner Rothschild, researcher Hen Dotan, and entrepreneur Talmon Marco, based on research conducted at the Technion.

Key takeaways

H2Pro belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect H2Pro to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of H2Pro from memory before moving on to harder problems.

Reference excerpt

H2Pro is an Israeli company that develops electrolyzer systems for the production of green hydrogen. The company was co-founded in 2019 by Technion professors Gideon Grader and Avner Rothschild, researcher Hen Dotan, and entrepreneur Talmon Marco, based on research conducted at the Technion. It is headquartered in Caesarea, Israel.

History H2Pro was founded in 2019 to commercialize a two-step water-splitting process developed at the Technion. In October 2019, Hyundai invested in the company as part of a series of investments in hydrogen technology firms. The company has received backing from Breakthrough Energy, the climate fund founded by Bill Gates, from Hong Kong entrepreneur Li Ka-shing's Horizons Ventures, and from Singapore's Temasek Holdings. In March 2021, H2Pro raised US$22 million in a round joined by Gates, Li Ka-shing, Sumitomo Corporation and Hyundai, intended to move its electrolyzer technology from laboratory prototypes toward commercial-scale manufacturing. In January 2022, ArcelorMittal invested US$5 million in H2Pro through its XCarb innovation fund. As of 2021, the company had raised over US$100 million from investors including Sumitomo Corporation and Yara. In March 2023, H2Pro signed a memorandum of understanding with Sumitomo Corporation, under which Sumitomo would integrate H2Pro electrolyzers at a scale of hundreds of megawatts, primarily for green ammonia production. The agreement was estimated at US$250 million through the end of the decade. In 2025, Talmon Marco, who had served as chairman and CEO since the company's founding, remained chairman, and Tzahi Rodrig was appointed CEO. A 50-kilowatt system operates at the company's Caesarea facility, and a 500-kilowatt system was scheduled to begin operating in early 2026 in Tziporit in northern Israel, expected to be the first green hydrogen production in the country, with a larger system of up to 50 megawatts planned in Spain or Portugal.

Technology H2Pro's electrolysis technology is based on a method known as decoupled water electrolysis (DWE), which separates the hydrogen and oxygen evolution reactions in time rather than space. Unlike conventional electrolysis, which produces hydrogen and oxygen simultaneously at different electrodes separated by a membrane, DWE operates in two distinct phases, eliminating the need for a membrane. In the first phase, hydrogen is generated at one electrode while a "battery-like" nickel hydroxide electrode charges, converting to nickel oxyhydroxide; no oxygen is released. In the second phase, the current is reversed: oxygen is produced while the battery electrode discharges back to nickel hydroxide, with no hydrogen released. Because the two gases are never produced at the same time, the risk of gas mixing is eliminated without a membrane. This membrane-less, temporally separated process is designed to allow operation under the intermittent power conditions of solar and wind energy; although individual cells alternate between hydrogen and oxygen generation, multiple cells are operated in parallel to ensure continuous overall gas production. The 2019 scientific paper describing the process reported an average 98.7% voltage efficiency, with electrical energy consumption of 39.9 kWh per kilogram of hydrogen.

Worked examples

Example 1 — a first encounter with H2Pro

Start with the simplest possible case. Write down what H2Pro claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to H2Pro before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about H2Pro ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of H2Pro

In research: H2Pro appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses H2Pro in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: H2Pro is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2019 establishments in Israel, Hydrogen, Sustainable energy, so understanding it makes those chapters shorter.
In everyday life: Look for H2Pro outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is H2Pro in simple terms?

Why does H2Pro matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study H2Pro?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
