Ukraine's Robotic Army: 30% of Forces Automated by 2026

Ukraine to Replace 30% of Troops with Military Robots by 2026

Drone warfare is front and center in Russia's war against Ukraine and US President Donald Trump's war against Iran. Much of the attention goes to unmanned aerial vehicles, but robotic applications on the ground are rapidly emerging as well. That brings up the question of how best to power these devices, and green hydrogen stakeholders are among those making the case for fuel cells.

The Robotic Army Of The Future Is Already Here

Ukraine's years-long fight to hold its territory against a much larger, far more populous foe has stretched the ranks of its active duty military to the bone. However, Ukraine continues to muster up an effective fighting force, and drones are part of the reason why.

"Ukraine is no longer just supplementing its infantry with tech - it is replacing infantry in many cases with drones, ground robots, sensor networks, minefields and artillery cued by unmanned systems," observes Defense News reporter Katie Livingstone.

The idea of robotic ground forces has been percolating in the US, too. Back in 2014, Scripps News summarized robotics-centered discussions under way at the US Army, which was casting an envious eye over at the Navy's ability to run its ships with fewer personnel. The goal of replacing 25% of Soldiers with robots was under discussion at the time.

Out of necessity, Ukraine has leapfrogged ahead. In an interview posted on YouTube, the commander of Ukraine's 3rd Army Corps, Andrei Biletsky, cited 30% as the replacement goal for 2026 - that's right, this year - with the figure reaching as high as 80% in the future.

The Green Hydrogen Solution

The fuel cell angle is of interest to the extent that military applications can support early-stage industries with broader civic benefits. The US Air Force, for example, was instrumental in pushing the solar power market during the Obama administration, when PV costs were high and civilian uptake was low. Concurrently, the Department of Defense has been tinkering around the edges of green hydrogen, produced from water in electrolysis systems with a jolt of clean electricity from solar arrays. That includes mobile units for use in remote locations where water and sunlight are more accessible than trucked-in fuels.

With that in mind, let's take a quick look back at the Michigan startup Sesame Solar. The company surfaced on the radar last fall, when it partnered with the drone manufacturer Heven AeroTech on a mobile green hydrogen solution for Heven's fuel cell UAVs, deploying solar power

"By generating its own power through solar energy, hydrogen generation, and low-pressure solid-state storage, Sesame's Mobile DRNs function as the first closed-loop, mobile refueling stations for Heven's Z-1 platform," Sesame explained.

The Sesame "Mobile Nanogrid" is optimized for field assembly by a skeleton crew. One person can set up the system in about 15 minutes, including battery energy storage as well as hydrogen storage.

The setup supports Heven's focus on rapid assembly in the field. "Upon arrival, drones can be assembled and deployed in just five minutes - no tools required - and refueled instantly from Sesame's solid-state hydrogen tanks, eliminating wait times for hydrogen generation," Sesame explained.

More Robots On The Ground

If you're wondering why not just bottle up the solar energy for battery-powered drones, that's a good question. Fuel cell advocates draw attention to longer flight times, larger payloads, and longer lifecycle, though batteries can also cover a wide range of applications.

A combination of batteries and fuel cells is also emerging. Last month, for example, the Canadian firms First Hydrogen and Exodus Actuation Solutions Inc. (aka RoboticsCo) announced their intention to produce an unmanned ground vehicle for various applications beyond military purposes, deploying solar, batteries, and fuel cells.

Green Hydrogen And The Nuclear Connection

As the fuel supplier in the new partnership, First Hydrogen is focused on producing green hydrogen from water, deploying renewable energy to run the electrolysis systems. The company has also established a First Nuclear branch to enlist the new generation of SMRs (small modular nuclear reactors) to run electrolysis systems.

"These compact and efficient reactors offer a consistent and scalable energy supply, enabling continuous large-scale hydrogen generation while maintaining sustainability goals," the company enthuses, though nuclear energy strains the meaning of "sustainability goals."

Compared to solar and other renewables, SMRs are costly and largely unproven. The first SMRs in the US are not expected to produce electricity until 2030, barring the usual delays and cost over-runs typical of nuclear power plants. Meanwhile, new utility-scale solar power plants were already springing up by the handful last year despite President Trump's anti-solar energy policy. More of the same is expected in the coming years.

Climate change is also putting a crimp in the nuclear plan. Back in 202, S&P Global was among those anticipating that "climate change-exacerbated water shortage issues pose a near-term and longer-term performance risk to power plants, such as hydropower and nuclear, around the world."

More Green Hydrogen For The USA, Some Day

Nuclear energy aside, prospects for the green hydrogen industry here in the US dimmed after Trump took office last year and trashed the new Regional Clean Hydrogen Hubs program. The damage is done, though a glimmer of life remains in the ammonia fertilizer area.

Trump's war in Iran has sent the cost of ammonia fertilizer through the roof in global markets, due to the industry's dependence on natural gas to produce the hydrogen needed for ammonia (chemical formula NH3). Local electrolyzer facilities powered by wind or solar energy can provide a more economical alternative.

Farmers in the US have been impacted by the price spike as well. Although the US produces a significant amount of ammonia fertilizer domestically, farmers also import a significant quantity of fertilizer.

Keep an eye on Minnesota, where a US ag tech startup has launched an effort to establish a network of green ammonia fertilizer facilities powered by wind and solar. In addition to reducing and stabilizing fertilizer costs, the new facilities will also help wind turbine owners avoid curtailment-related revenue losses.
