Three guys and a revolutionary idea

In 1985, three young men developed one of the first electronic automation calculators. One of the most innovative applications involved the world of hydrogen. When no one was talking about sustainability, these three boys understood the importance of renewable energy and the great prospects of this business. Another boy joined them-and together they designed a new technology to produce energy with hydrogen.

There are numerous benefits for the environment that result from the use of the technologies produced by ErreDue: working for the efficiency and optimization of the production cycle generates important benefits not only for the customer but also for the environmental context in which the customer operates.

  • SOME
  • On-site gas production eliminates greenhouse gas emissions from cylinder transportation.

  • On-site production of gas directly at the required pressure provides significant energy savings and can eliminate the need for a compressor.

  • Hydrogen used as an energy carrier makes the best use of existing renewable sources and facilitates their development and deployment.

  • Increased safety in work environments: the risk of accident is reduced because the gas produced at the pressure averts the danger of bursting and eliminates critical issues related to transport and handling of compressed gases.
