TTP and PlusZero pledge green hydrogen revolution

Scottish ‘green hydrogen’ startup PlusZero has joined forces with Cambridge technology consultancy TTP to develop a highly efficient electrolyser capable of producing limitless supplies of the ultra-clean energy. 

PlusZero creates portable, zero-carbon generators powered by green hydrogen produced from its own electrolyser asset in Scotland’s Western Isles – utilising surplus onshore renewable electricity generated there. 

PlusZero is supported in the Step Change Project with TTP by Edinburgh company Logan Energy.

In 2024, PlusZero plans to significantly expand its electrolyser facility in the Western Isles, cementing its place as a leader in UK green hydrogen production. 

The Step Change Memorandum of Understanding, signed by PlusZero and TTP at the All-Energy Conference in Glasgow, signals the start of a research and development phase between the companies to deliver a new generation demonstrator electrolyser that addresses current scalability challenges in the sector. 

TTP, one of Europe’s leading technology and product development companies, has used its DeepTech expertise, the results of which will now be demonstrated as part of its broader offering in sustainable technologies.

Not only will TTP’s electrolyser excel at efficient hydrogen generation, but also it has been designed to be low cost and suitable for mass production to address the worldwide bottleneck in electrolyser availability.

David Amos, managing director at PlusZero said: “At PlusZero, our mission is to supply near limitless green hydrogen – displacing traditional fuel sources that emit harmful greenhouse gases. 

“We believe it is not unrealistic to suggest that the UK Hydrogen Strategy target of 10GW low carbon hydrogen production capacity by 2030 could be met by Scottish green hydrogen alone. However, limited green hydrogen production capacity has created a massive scalability challenge.

“We want to change that, and through this exciting partnership with TTP, we believe that we can. Step Change is a ground-breaking project that will aim to strip inefficiencies and costs out of green hydrogen production and provide a genuine solution to what is currently an industry problem. 

“PlusZero is working with some of the most experienced and creative people in the sector to make hydrogen happen. Together with TTP we hope to demonstrate that a rapid transition to a clean energy future is within grasp.”

Charles Cooke, TTP’s Sustainable Energy Technology lead, is equally excited about the potential of the tie-up. He said: “In line with climate change targets, the production of green hydrogen needs to ramp up rapidly. 

“TTP has taken a core technology that can be low in cost and work efficiently when coupled to fluctuating renewable power and applied innovative design approaches to create a new electrolyser that will be suitable for mass production.”

“The Step Change partnership with PlusZero provides an ideal testbed as our technology emerges from the lab. Testing in the context of PlusZero’s ongoing operations in the Western Isles will ensure that the electrolyser integrates seamlessly with existing infrastructure to enable efficient and reliable hydrogen generation and support the adoption of green hydrogen.

“Eventually this will mean widely distributed green hydrogen generation wherever there are surpluses in renewable electricity from the wind or the sun.”
