About ITM Power

ITM is at the forefront of the green hydrogen industry, designing and manufacturing cutting-edge PEM electrolysers that are instrumental in global decarbonisation efforts. With over two decades of scientific expertise, we’ve established ourselves as industry leaders in clean energy technology.

Our Journey and Growth

As pioneers in green hydrogen technology, ITM is offering the most advanced PEM electrolyser technology in the world. Founded in 2000, ITM Power PLC was one of the first companies of its kind to be listed on the AIM market of the London Stock Exchange. Headquartered in the UK, our state-of-the-art manufacturing facility is the world’s first largest PEM Gigafactory in commercial operation, and home to our R&D and manufacturing. ITM Power Germany is our hub in the heart of the EU. This facility not only houses regional functions including business development and engineering, but also our Aftersales services with the ability to quickly deploy stacks.

Innovation and Impact

Our PEM electrolysers are deployed in some of the world's largest green hydrogen projects. We continue to push the boundaries of technology, enhancing cost-effectiveness and sustainability.

Join Our Mission

ITM is in the midst of a transformative phase, focusing on streamlined delivery and operational excellence. We're seeking talented individuals who share our passion for clean energy and our drive to make a tangible impact on the world's transition to net-zero.

You will be working with an inspiring bunch of people, encouraging each other to be the best we can. We’ve come a long way, join us in the next step of our incredible journey!
