A four-legged robot dog designed to detect toxic substances could soon become the first responder sent into dangerous areas and help firefighting crews assess the damage without risking their own safety.

The remote-controlled detection robot was developed by researchers at the Graz University of Technology (TU Graz) in Austria. It is a compact, quadruped system that also incorporates measurement devices already used by fire services.

According to the research team, the detection robot has already been extensively tested by emergency services as part of large-scale pollutant drills. It has proved its ability to provide real-time data from danger zones.

Gerald Steinbauer-Wagner, PhD, an associate professor and robotics researcher at TU Graz, revealed that the dog can be deployed on missions ahead of firefighting crews. “It measures pollutant concentrations and delivers the data together with a camera image in real time from the danger zone,” Steinbauer-Wagner explained.

First into danger

In chemical accidents, emergency crews need to identify hazardous substances quickly while operating under dangerous conditions. Firefighters must typically don bulky protective suits, such as a Level A or B Hazmat suit, prior to entering contaminated areas to take measurements.

Although necessary to ensure total isolation from hazardous environments, the process can consume valuable time during an emergency. To address this issue, the team turned to robotics.

As per the researchers, the robotic dog can be sent in before firefighters to collect critical information from the scene. “This allows the emergency services to assess the situation without having to enter the danger zone themselves,” Steinbauer-Wagner continued.

The technology reduces firefighting teams’ direct exposure to toxic substances. It could significantly improve their safety during industrial accidents and hazardous materials incidents.

“Based on a comprehensive requirements analysis, we developed an appropriate robotic strategy and integrated it into existing standard operational procedures,” Steinbauer-Wagner added. “This should ensure seamless collaboration between man and machine during the operation.”

A safer perspective

Instead of creating a new system, the team made it compatible with existing fire-service procedures. The researchers conducted an extensive requirements analysis before integrating it into established hazardous materials response protocols. The robot relies on commercially available parts for mobility, sensing, data processing, communication, and visualization.

“The results of the field tests were extremely promising in terms of mobility, user-friendliness and effectiveness,” Steinbauer-Wagner reported. Meanwhile, a recent potential analysis supported by the Austrian Research Promotion Agency (FFG) highlighted several advantages of the technology.

Gerald Czech of the Austrian Federal Fire Service Association emphasized that, in the event of a real incident, he would send the robot dog into the contaminated area before the firefighters go in. “For the fire service, every minute counts during a hazardous materials operation,” he said in a statement.

Czech further said receiving measurement data and images from the danger zone while crews are still putting on protective gear could save valuable time during an emergency. “This increases the safety of the crew and improves operational command,” he concluded.

Experts from the Styrian and Upper Austrian fire service associations, TU Graz, the University of Applied Sciences Upper Austria, as well as the Disaster Competence Network Austria, support the use of detection robots. They propose making them a permanent part of fire departments’ hazardous materials response teams.

US energy storage startup Peak Energy has recently joined forces with leading car manufacturer General Motors (GM) to develop sodium-ion batteries designed for grid storage.

The Colorado-based energy storage company announced the new partnership on June 9. The project will bring together its proprietary passively cooled battery and GM’s sodium-ion cells.

Under the novel agreement, General Motors will design and develop the sodium-ion cells at its battery laboratories in the state of Michigan. It will moreover retain exclusive manufacturing rights. Peak Energy will integrate the cells into its energy storage systems.

“In grid-scale stationary storage systems, if we can make the cell safer and more robust, we can remove complexity elsewhere in the system,” GM reported. “That can translate into a quieter, simpler, lower-maintenance ESS for the customer.”

Sodium-ion storage push

According to both companies, the technology could provide a cheap alternative to today’s dominant lithium-iron phosphate (LFP) battery systems. It could also improve reliability and reduce energy waste.

“Lowering the cost of energy is one of the most important issues facing America today,” Landon Mossburg, Peak Energy CEO and co-founder, said. He added that the firm aims to deliver a safer, lower-cost, and faster-to-deploy energy storage system that can meet the growing US power demand without raising consumer costs.

Peak Energy has developed a proprietary passively cooled battery energy storage system. In essence, this means that it does not rely on active cooling to maintain safe operating temperatures. The firm argued that eliminating cooling equipment reduces both upfront costs and operational complexity.

The sodium-ion system can reportedly reduce energy storage costs by around 20 percent compared with conventional solutions. It can furthermore deliver over 99 percent uptime.

Mossburg stressed the significance of the project. “The future of grid storage will be defined by affordability, reliability and American innovation,” he noted. “We’re thrilled to partner with GM to bring a better solution to the American energy economy.”

A strategic partnership

Replacing conventional LFP-based storage systems with Peak Energy’s passively cooled technology could potentially cut annual battery storage energy waste in the US by up to two terawatt-hours (TWh). That amount of electricity would be enough to power a mid-sized city for an entire year.

“At GM, we know that the application should determine the battery, and for grid-scale stationary storage, sodium-ion is the right solution,” Kurt Kelty, GM’s VP of battery and sustainability, said in a press statement.

According to GM, eliminating active cooling can significantly improve energy storage systems. Active cooling relies on additional equipment, leads to higher energy losses, requires more maintenance, and increases the risk of component failures. All of this can drive costs higher over time. The firm is certain that Peak Energy’s platform will deliver lower costs, greater reliability, and less maintenance.

“Peak is already demonstrating the value of sodium-ion through their innovative energy storage platform, and together we’re working to push those benefits even further with our next-generation cell – helping deliver more reliable, lower-cost energy storage at scale for the US grid,” Kelty concluded.
