New solutions in the industry
The company Caterpillar, popularly known as Cat, recently announced that it has successfully tested a large-scale hydrogen fuel cell, which was tasked with providing backup power to a multi-megawatt data center. 
Details of the project
The demonstration took place in cooperation with the IT giant Microsoft and Ballard Power Systems in the USA. The project was designed to test how the hydrogen fuel cell provided by Cat would perform as a backup power supply in adverse terrain and temperature conditions - above 1800 m.a.s.l. and temperatures below zero.
The simulation maintained emergency power for 48 hours in a Microsoft-owned digital data storage center, where the technology provided by Caterpillar was integrated into the power system - the package consisted of two Cat Power Grid Stabilization (PGS) energy storage systems with a 1.5 MW hydrogen fuel cell.
Comments after the demonstration
The project was commented on by representatives of all the companies involved in the project, as a great success and an opportunity for large corporations to implement innovations in the field of energy acquisition.
The project was also supported and supervised by the United States government through a specially organized initiative, which aimed to develop hydrogen technologies in various sectors of the economy. During the entire test, factors such as safety, technical-economic issues and greenhouse gas emissions were analyzed. 
What future in the construction industry?
Many popular construction machinery manufacturers are conducting similar research on innovative ways of energy acquisition - there is even an extensive article about it on our website.
This is undoubtedly due to the ongoing reduction of combustion and construction machinery is no exception, and now you can find excavators or loaders powered by electric batteries in a full or hybrid way. How Cat's technology will be used in this manufacturer's equipment, we will find out in the future.
