The CEO of Siemens Energy has spoken of the challenges facing the green hydrogen sector, telling CNBC that there was “no commercial case” for it at this moment in time.
In comments made during a discussion at CNBC’s Sustainable Future Forum on Tuesday, Christian Bruch outlined several areas that would need attention in order for green hydrogen to gain momentum.
“We need to define boundary conditions which make this technology and these cases commercially viable,” Bruch, who was speaking to CNBC’s Steve Sedgwick, said.
“And we need an environment, obviously, of cheap electricity and in this regard, abundant renewable energy available to do this.” This was not there yet, he argued.
Hydrogen can be produced in a number of ways. One method includes using electrolysis, with an electric current splitting water into oxygen and hydrogen.
If the electricity used in this process comes from a renewable source such as wind or solar then some call it green or renewable hydrogen.
While there is excitement about the potential of green hydrogen in some quarters, it’s currently expensive to produce. Indeed, National Grid describes grey hydrogen as being the “most common form of hydrogen production” today.
This grey hydrogen, it says, “is created from natural gas, or methane, using steam methane reformation but without capturing the greenhouse gases made in the process.”
In his remarks, Bruch also stressed the importance of building up an industry to support the commercialization of green hydrogen.
Technical systems and an operational knowledge built up over 10 to 15 years were crucial, he explained, noting that this was what one normally saw in the power industry.
“This is all still to come to make it … a commercial system,” Bruch said. “So the biggest problem is [that] under the current boundary conditions there is not yet a commercial case for green hydrogen.”
Another participant in Tuesday’s discussion was Marco Alverà, the CEO of Italian energy infrastructure giant Snam.
Among other things, he talked about the importance of establishing a framework to encourage the development of more sustainable industry.

“You need the fine print and the policies to incentivize or make it mandatory: to switch from grey to green, to switch from gas to hydrogen, to switch from coal to hydrogen,” he said. “And then it will happen very fast.”
Described by the International Energy Agency as a “versatile energy carrier,” hydrogen has a diverse range of applications and can be deployed in sectors such as industry and transport.
One area that has generated a significant amount of debate in recent years is the use of hydrogen fuel cells in cars.
“On private cars, or passenger cars, it’s a very, very difficult use case,” Siemens Energy’s Bruch said. “It’s not the use case I would go to first.”
“I think it’s much more reasonable to talk about hydrogen use either in … heavy duty mobility or in certain industrial applications,” he went on to add.
“We talk about green steel or green refining processes, which are much more reasonable, much more CO2 effective, and offer a much more beneficial cost environment to make green hydrogen possible.”
Enphase Energy just launched a new off-grid system that lets homeowners power their homes without a utility connection – even for extended periods. The California-based Enphase says the off-grid setup delivers a seamless way to live independently from the grid while still using solar, batteries, and a standby AC generator.
A full off-grid setup
The new system combines Enphase’s IQ Battery 5P with embedded grid-forming microinverters, IQ8 Series Microinverters with Sunlight JumpStart, and a third-party standby AC generator. The components work together to supply power to a home and automatically manage energy sources to maximize efficiency and reliability.
If the batteries are drained and the generator runs out of fuel, the Sunlight JumpStart feature can automatically recharge the batteries the next morning once the sun comes up.
The IQ Battery 5P delivers 3.84 kVA of power per 5 kWh of capacity, and systems can be scaled up to 40 kWh and 15.4 kVA. That’s enough power to start big household appliances like HVAC systems or water pumps. The IQ System Controller 3G provides the backbone, managing solar, batteries, and generator inputs to deliver up to 46 kVA of off-grid power.

Smarter control and connectivity
Each system connects to the cloud through Enphase’s IQ Combiner 5C HDK, which bundles solar interconnection, communications, and metering into one box. For homes without reliable broadband, the built-in 4G LTE Cat 4 modem keeps the system online for monitoring, firmware updates, and remote support.
Homeowners can manage everything from the Enphase App – from solar generation and battery status to generator integration and load control.
Why it matters
As grid outages become more common and homeowners look for ways to gain energy independence, off-grid systems like this are becoming more appealing.
“With the launch of our off-grid solution, we are giving homeowners a reliable path to complete energy independence,” said Nitish Mathur, Enphase’s SVP of customer experience. Enphase says over 100 homes are already operating entirely off-grid using its technology. The company plans to expand availability beyond the US in 2026.

Global offshore wind targets are still strong enough to triple global capacity by 2030, despite the US’s offshore wind stagnation under Trump. A new analysis from energy think tank Ember and the Global Offshore Wind Alliance (GOWA) shows that the rest of the world is charging forward, underscoring confidence in offshore wind as a cornerstone of future clean energy systems.
Based on the latest NHTSA report, Tesla’s ‘Robotaxis’ keep crashing in Austin, Texas, despite ‘safety monitors’ preventing an unknown number of crashes.
Under an NHTSA Standing General Order SGO, automakers are required to report crashes involving their autonomous driving (ADS) and advanced driver assistance systems (ADAS) within five days of being notified of them.
For years, Tesla was only reporting ADAS crashes, since, despite the names of its Autopilot and Full Self-Driving systems, they are only considered level 2 driver assistance systems.
Since the launch of the Robotaxi service in Austin, Texas, where Tesla moved the supervisor from the driver’s seat to the passenger seat, it has now reported its first few crashes under the ADS reporting.
This week, NHTSA has updated its crash report and revealed a 4th crash that happened in September:

As we previously highlighted, when it comes to both ADS and ADAS crash reporting, Tesla abuses the redacting capacity and hides most information about its crashes, unlike most of its competitors.
Therefore, we don’t have much information about this new crash, but it reportedly occurred in a parking lot and involved a Tesla Robotaxi crashing into a “fixed object,” resulting in property damage.
What’s most interesting about this crash is that it comes as Tesla released the first bit of data about its Robotaxi program in Austin.
During its earnings call last week, Tesla confirmed that the Robotaxi fleet has traveled 250,000 miles since its launch in late June.
Therefore, Tesla Robotaxi currently crashes at a rate of about once every 62,500 miles. That’s with a safety monitor with a finger on a kill switch, ready to stop the vehicle at all times.
We have no data on how often Tesla’s safety monitors prevent crashes in its robotaxis.
For comparison, the NHTSA report lists 1,267 crashes involving Waymo vehicles. However, Waymo’s robotaxis have covered over 125 million fully driverless miles since inception. That’s a crash every 98,600 miles and without any onboard safety monitor.
Electrek’s Take
That’s the problem with comparing Tesla and Waymo.
At least we can now clearly see that Waymo’s incident rate is much lower than Tesla’s, but that’s with a safety monitor in Tesla robotaxis that prevents an untold number of crashes.
The actual difference could be 10x higher. We simply don’t know. Tesla has always refused to share any data regarding disengagement or intervention rates.
One thing is clear: Tesla is way behind Waymo in autonomous driving safety.
