From hydrogen physics to business decisions: a unique tool for anyone who must present solid numbers to clients, partners, and investors.

You need to present an offer, a quote, or a feasibility study on hydrogen — but the numbers must be credible.

Anyone working in the energy transition knows it well: in front of a client or an investor you need solid data. How much hydrogen is needed? How much does it cost to produce? How much storage is required to guarantee the requested autonomy? Getting these numbers wrong means losing credibility — or, worse, losing the contract.

The problem is that calculating them correctly requires specific technical skills. Hydrogen density at high pressures (such as 350 or 700 bar) does not follow the ideal gas laws, and a mistake here undermines the entire cost estimate and the sizing of the tanks.

That’s why Costruzioni Energetiche developed H2-Optimizer Pro: a tool that gives you reliable figures and a professional ready-to-use report, in seconds. Not a simple calculator, but an ecosystem that turns physical data into business decisions

H2 Global Advisor AI: your technical-economic feasibility report

Optimize storage and analyze operating costs.

The core of H2-Optimizer Pro is the H2 Global Advisor AI module, which integrates the power of GPT-4o to turn a few parameters into a true Technical-Economic Feasibility Report, ready to present.

By simply entering the location and energy parameters, the artificial intelligence generates in seconds:

• Needs analysis — automatic calculation of the required hydrogen production
• Energy balance — verification of coverage via renewable sources
• Safety standards — identification of applicable ISO and ATEX regulations
• Bilingual report (IT/EN) — documentation ready to attach to commercial offers or to present to partners and investors

It is the ideal tool for those who must make fast, accurate decisions in the energy transition sector, without having to build every analysis from scratch.

The calculation engine: scientific precision, not approximations

Technical-Economic Feasibility Report

Behind every report there is a physics engine that uses the thermophysical database NIST-CoolProp, the same reference used in scientific and industrial fields. This ensures that the numbers you build your offer on are solid.

The H2 Calculator module lets you obtain:

• Density and real mass calculation — accurate data based on pressure (bar) and temperature (°C), removing the approximations typical of generic calculators
• Economic analysis (partial LCOH) — the cost of the energy needed for production, based on electrolyzer efficiency and the cost per kWh
• Charging time estimate — tank filling time based on the system flow rate
• Professional bilingual reporting — a technical PDF in Italian and English, ready for technical reports and commercial offers

H2 Business Case: from real solar data to return on investment

The new H2 Business Case module is the tool that turns a project idea into concrete, presentable numbers. By simply entering the location and energy demand, the system builds a complete economic analysis based on real solar data, not generic estimates.

Here’s what it does in a few seconds:

• Real solar data from the location — the system connects to the official European database PVGIS (Joint Research Centre, European Commission) and downloads the actual solar yield for the exact project site, with optimal tilt and real specific yield. It’s the data you would otherwise have to find and rework manually.
• Hybrid system sizing — it automatically calculates component sizes (PV plant, electrolyzer, fuel cell, hydrogen storage) according to a realistic model where PV covers direct consumption and hydrogen acts as a reserve for the required autonomy.
• Detailed investment (CAPEX) — cost estimate for each component, with the option to enter your real supplier prices for a tailored result.
• Multi-year ROI and payback — projection of return on investment over 15 years, with three energy price scenarios (low, base, high) and calculation of the payback year, all shown in a clear chart.

It’s the analysis that enables consultants, designers, and companies to present clients and investors with a solid, credible economic feasibility assessment, without having to build every calculation from scratch.

Why choose a professional tool?

Today, accuracy is a competitive asset. H2-Optimizer Pro is not a simple script: it is based on NIST-CoolProp thermophysical data and refers to industry standards such as ISO 14687. Working with reliable data means ensuring end customers safety, efficiency, and a realistic estimate of investment payback time (ROI).

In practice: you present stronger offers, with less risk of errors, and you look professional even when hydrogen is not your technical specialty.
