Most recently, Donaldson served as CFO of ACME Cryogenics, and played a pivotal role in its sale to Dover Corporation in 2021.

Fluitron is a portfolio company of Ara Partners, a private equity firm that specialises in decarbonisation investments.

Tuan Tran, a Partner at Ara Partners, said, “John is a highly experienced finance executive with a very strong background in high-growth situations and is well-versed in Fluitron’s end-markets. He will be a critical member of the senior management team as we establish a hydrogen platform to service the global energy transition market.”

Donaldson said Fluitron is positioned to become a major worldwide contributor to hydrogen infrastructure.

He said, “Fluitron is a technology leader in hydrogen systems and has over 40 years of experience developing clean energy solutions and infrastructure globally. I look forward to working with the Fluitron team to take the company to the next level.”

Previous roles include CFO and Chief Operating Officer of League Collegiate Outfitters, CFO (interim) of New Hudson Facades, CFO of Bluestem Brands, CFO of Tray-Pak Corporation, and CFO of 3SI Security Systems.

In November 2021 Fluitron bought Bethlehem Hydrogen, which marked the first step in building a global platform of hydrogen infrastructure and refuelling solutions.
