Innovative Propulsion for Expanding Satellite Markets

Giner is at the forefront of revolutionizing satellite propulsion with our proprietary static water vapor feed PEM electrolyzer, designed to meet the growing demands for safer and more efficient satellite operations. As the satellite industry continues to expand, with over 8600 small satellites scheduled for launch in the next decade and a projected market value of $234 billion for medium to large satellites by 2028, the need for innovative solutions in satellite maintenance and propulsion is critical. Key drivers for this surge include advancements in earth imaging, observation, telecommunications, and internet connectivity.

Traditionally, satellites have relied on hydrazine-based thrusters for maintaining orbital position—an essential function for operational continuity. Despite its effectiveness as a propellant, hydrazine (nominally priced at $100/pound) poses significant safety risks and logistical challenges. It requires specialized handling and protective measures during loading, which can only be performed at the launch pad, significantly increasing overall mission costs and complexity.

Giner's Cutting-Edge Electrolyzer Technology

In response to these challenges, Giner has developed a cutting-edge technology that simplifies satellite propulsion systems. Our high-pressure static water vapor feed PEM electrolyzer eliminates the need for additional bulky components such as water tanks and pumps required by traditional electrolyzer technology, which add unwanted weight and occupy valuable space within the satellite. This innovation not only reduces the overall system size and weight but also enhances the feasibility of hydrogen as a green propellant. By enabling on-demand hydrogen production directly in orbit, our technology facilitates a more integrated and streamlined satellite configuration process, allowing satellites to be fully fueled and ready for launch during assembly.


Impact and Future Direction

This system has been successfully tested by leading satellite thruster and propulsion system manufacturers, marking a significant milestone in satellite propulsion technology. As we continue to refine and implement our technology, Giner is committed to providing sustainable, efficient, and safer propulsion options that align with the evolving needs of the global satellite industry.
