Supporting the stationary power sector with heating and cooling innovation

As the world continues the important push to a net-zero tomorrow, today’s engineers are tasked with redesigning the world’s power infrastructure, with a focus on zero-emission alternatives.

Stationary power applications are playing an important role in transforming the way renewable energy is generated, stored and distributed, supporting grids around the world and providing off-grid power to homes, businesses, telecommunications networks, utilities, and others.

However, whether it is battery energy storage systems for solar farms or hydrogen fuel-cell power systems to power off-grid mines and construction sites in some of the harshest environments, effective thermal management of these applications is one of the most important challenges for engineers to overcome.

Case study: Cooling hydrogen fuel-cell stationary power

In 2023, Grayson was approached to develop a thermal management solution for a new hydrogen fuel-cell power generation application capable of delivering over 1000kW of clean, off-grid power.

To help meet the demanding cooling and flow requirements, we developed our 400V AC hydrogen fuel-cell cooling module. Mountable to the roof of a standard 20ft portable system, the 2-fan cooling module delivers a maximum cooling output of 190kW at 40°C and a flow rate of 290 l/min.

Why stationary BESS thermal management matters

In battery energy storage systems (BESS), the frequent charge and discharge of high-capacity lithium-ion battery stacks results in increased heat dissipation due to internal resistance and electrochemical reactions. Effective thermal management ensures these batteries maintain their optimum operating temperature, preventing accelerated capacity loss and premature battery degradation.

Why stationary hydrogen fuel-cell power thermal management matters

Hydrogen fuel cells provide instant clean power generated on demand by combining hydrogen and oxygen in an electrochemical reaction to produce electricity and water. The other notable by-product of this exothermic process, however, is heat. Additionally, internal inefficiencies, such as resistance to electron flow within the cell, contribute to heat production. Effective cooling is essential to maintain optimal performance and power output as excessive heat can lead to component degradation, reduced efficiency, and potential safety hazards.
