In hospitals, continuous power supply is not just a technical requirement, but an essential condition for patient safety and the operation of critical medical equipment.
Traditionally, diesel generators have been the go-to emergency solution for power outages. However, the adoption of fuel cells as energy support systems is gaining attention due to their ability to provide clean, reliable and low-emission energy.
Service continuity and reliability compared to traditional generator sets
Service continuity is a fundamental parameter in hospitals. In fact, equipment such as ventilators, infusion pumps and imaging systems require an uninterrupted power supply, especially during blackouts. Diesel generator sets, currently the most widely used, have certain limitations in terms of backup power performance. In fact, they can have starting problems, as well as sub-optimal performance over the long term.
Fuel cells, used as auxiliary generation systems together with battery systems, can offer a valid alternative to diesel generators. Batteries can cover the short interval when a blackout occurs, while fuel cells guarantee energy availability for a long period, up to several hours.
Furthermore, thanks to the absence of moving parts, fuel cells are less subject to mechanical wear and possible breakage than internal combustion engines.
For a hospital, therefore, the use of fuel cells combined with battery systems is an effective and reliable system that can offer effective protection against power outages that could compromise critical clinical processes, reducing the risk of medical equipment failure or danger to patients’ lives.
Clean energy in healthcare: emissions, noise and air quality
Today, blackouts are on the rise compared to the past due to changes in the electricity grid linked to the introduction of renewables. This means that emergency systems capable of ensuring continuity of power supply are being used more and more frequently. In this context, the environmental impact of the solutions adopted is an increasingly important aspect of hospital energy design.
Diesel generators produce direct emissions of nitrogen oxides, sulphur dioxide, fine particulate matter and carbon dioxide, all substances recognised for their negative effects on public health and the environment.
Fuel cells, on the other hand, convert hydrogen directly into electricity through an electrochemical process, with water as the only waste product and no harmful emissions. This significantly reduces the impact on air quality inside and outside healthcare facilities, contributing to a healthier environment for patients and staff. Furthermore, from an acoustic point of view, fuel cells operate at lower noise levels than diesel generators, promoting more comfortable conditions within the hospital facility.
System maintenance and scalability
Operating and maintenance costs are a key factor in evaluating energy backup technologies. Diesel generators require regular maintenance of mechanical components, such as filters, pumps and injection systems, as well as periodic testing to ensure they will start in an emergency. These operations involve recurring costs and require specific skills.
Although fuel cells are not exempt from maintenance requirements such as periodic replacement of certain components and performance monitoring, they benefit from the absence of moving parts and a simpler electrochemical process from an operational point of view. This results in less complex maintenance, leading to lower costs.
In addition, the modularity of fuel cells allows energy capacity to be easily adapted to the growing needs of the hospital.
Installation and operational management requirements
The integration of fuel cell systems into a hospital application requires specific technical and infrastructural assessments. Fuel cells can be implemented either as part of an internal microgrid or as a stand-alone backup unit. In many cases, the modular flexibility of the systems allows the energy capacity to be adapted to the specific needs of the facility, from small clinics to large hospitals.
As already mentioned, the installation of hydrogen fuel cells in healthcare facilities offers significant advantages over diesel generators:
- zero harmful emissions
- reliable power supply
- silent operation
- low maintenance and operating costs
- modular flexibility and scalability.
In addition to its obvious advantages, however, this technology also has some critical issues. The first limitation is the availability of hydrogen generation or supply infrastructure, which is currently under development, as well as the initial cost of hydrogen fuel cell systems, which is currently higher than that of traditional diesel generators. Furthermore, this technology requires storage systems. Hydrides offer a space-saving, safe and suitable solution for this type of application.
However, advances in hydrogen production and storage technologies are constantly improving access to hydrogen, making its widespread adoption in the healthcare sector more feasible.
