Logan Energy’s innovative mobile hydrogen refuelling system, MobileHRS, is returning to the Port of Leith in Edinburgh as part of a £1.1 million initiative to reduce emissions in the maritime sector.

Following the success of Innovate UK’s Clean Maritime Demonstration Competition 4 (CMDC4) – where Logan Energy, Waterwhelm, PlusZero Power, and Targe Towing Limited collaborated to produce, store, and utilise green hydrogen for shore power – the new CMDC6 project will take the next step: enabling the refuelling of hydrogen-powered vessels directly at the Port.

In a circular approach to sustainability, Waterwhelm will harness the heat generated by the hydrogen internal combustion engine to treat wastewater from a nearby facility, producing freshwater for green hydrogen production at the Port.

The advancing Green Hydrogen Production for Shore Power and Vessel Refuelling at the Port of Leith project is funded by UK Government through the UK Shipping Office for Reducing Emissions (UK SHORE) programme in the Department for Transport. UK SHORE has allocated over £230m since 2022 to develop the technologies necessary to decarbonise the UK maritime sector and capture the economic growth opportunity of the transition. Innovate UK, part of UK Research and Innovation, is the main delivery partner for UK SHORE interventions.

Leith isn’t the only location where MobileHRS is making an impact. Logan Energy is also working with Latent Drive, the University of Exeter, and Portland Port to demonstrate Latent Drive’s SeaStack electrolyser at Portland Port.

MobileHRS delivers hydrogen at 300bar, 350bar, or 450bar, from inlet pressures as low as 10bar. Several units are already operational, with more in development. For hiring or purchasing enquiries, please email info@loganenergy.com.

Logan Energy is proud to announce that it has been officially awarded the Alcumus SafeContractor accreditation, recognising the company’s unwavering commitment to health and safety excellence across all areas of its operations.

The accreditation follows a comprehensive assessment of Logan Energy’s health and safety management standards. It marks another milestone in the company’s mission to deliver safe, sustainable, and innovative hydrogen solutions.

Logan Energy, a leading provider of integrated hydrogen technologies, has expanded its footprint in Scotland with the opening of a new office at Energy Transition Zone’s flagship W-ZERO 1 building in Aberdeen.

The move strengthens Logan Energy’s presence in the North East, enabling the company to work more closely with existing clients and support the region’s growing demand for low-carbon energy solutions.

“Establishing a base within W-ZERO 1 places us at the heart of Aberdeen’s energy transition,” said Craig Stewart, Business Development Director, Logan Energy. “This move brings us closer to our customers and partners in the North East. With a local presence, we are better positioned to service and maintain existing hydrogen infrastructure while helping to deliver the next generation of projects across the region.”

W-ZERO 1, located at the entrance to the Energy Transition Zone (ETZ), is home to a range of innovative organisations, as well as the National Floating Wind Innovation Centre (FLOWIC). The building provides a collaborative environment designed to accelerate the energy transition by bringing together businesses across the hydrogen, offshore wind, and renewables sectors.

Logan Energy is a designer, supplier, and integrator of complete hydrogen production, refuelling, compression, storage, dispensing, and fuel cell solutions. The company has recently developed an innovative way of integrating systems to deliver flexibility, optimisation, and cost savings – while enhancing performance, reliability, and ease of use. Hydrogen refuelling stations in Scotland and the Czech Republic will be the first to benefit from these innovations when they are commissioned later this year.

Recognising that reliability, efficiency, and cost-effectiveness are vital to the hydrogen economy, Logan Energy also applies its extensive expertise to provide training, servicing, and lifecycle maintenance support.

“ETZ Ltd is delighted to welcome Logan Energy to W-ZERO 1. Their experience in hydrogen adds real strength to the low carbon and green energy ecosystem we are building here, and it’s fantastic to see another company commit to serving the North East directly from Aberdeen and the Energy Transition Zone.” – Neil Young, Director, Investment and Development ETZ Ltd

Scottish green hydrogen specialist Logan Energy Ltd is set to accelerate the deployment of hydrogen infrastructure in Sarawak, following the signing of a landmark Memorandum of Understanding (MoU) with Malaysian company H2 Energy Sdn Bhd last week.

After identifying the crucial role hydrogen will play in Sarawak’s Post COVID-19 Development Strategy 2030 (PCDS 2030), the Malaysian state looked to Scotland to find technology partners to help deliver its vision. In June 2025, Sarawak Deputy Energy and Environmental Sustainability Minister Datuk Dr Hazland Abang Hipni told the Energy Exports Conference (EEC) 2025 in Aberdeen that the state was ready to become a leader in ASEAN’s energy transition. During his visit, Datuk Dr Hazland met with a number of Scottish companies already playing key roles in global decarbonisation, including Edinburgh-based Logan Energy.

The MoU between Logan Energy and H2 Energy was signed during International Energy Week (IEW) 2025 in Kuching, Sarawak, in the presence of Sarawak Premier Datuk Patinggi Tan Sri Abang Johari Tun Openg, Deputy Prime Minister Datuk Seri Fadillah Yusof, Deputy Premier Datuk Amar Dr Sim Kui Hian, and Datuk Dr Hazland.

This strategic partnership marks a significant step towards accelerating the development and deployment of hydrogen solutions in Sarawak. By combining Logan Energy’s extensive hydrogen experience and expertise with H2 Energy’s local knowledge and operational capabilities, the two organisations are uniquely positioned to deliver hydrogen infrastructure projects in the region.

One such project is the Kuching Urban Transport System (KUTS), which will provide the 700,000 residents of Greater Kuching with a hydrogen-powered public transportation network.

H2 Energy has already delivered a hydrogen energy system at Long Loyang Clinic, which is powering critical services for over 2,000 residents in the rural, off-grid village. Logan Energy will support scaling the technology, potentially impacting tens of thousands of people living in rural communities across Sarawak.

About the partnership’s potential, Ms Sandra Liz Hon, Executive Director of H2 Energy Sdn Bhd, said: “This collaboration supports Sarawak’s ambition to lead ASEAN’s hydrogen economy while creating skilled jobs and delivering sustainable growth for local communities.”

“The success of a hydrogen infrastructure project isn’t measured the day it’s switched on,” said Craig Stewart, Business Development Director at Logan Energy. “It’s measured by its long-term reliability, efficiency, and low maintenance costs. Achieving that requires local skills, and building that capability will be a key focus of our collaboration with H2 Energy.”
