EIH2 is an Irish company led by environmental advocate and entrepreneur Pearse Flynn. 

We’re playing a lead role in the development of Ireland’s green hydrogen production and distribution capabilities.


We’re taking action with organisations like yours to deliver our zero-emissions future.


Ireland has committed to net zero emissions by 2050 but to achieve that we must transform our energy system.

Ireland’s current system is based on fossil fuels. If we’re to make real change we need to transition to renewable electricity supported by green hydrogen.

This is the same around the world but Ireland is at an enormous advantage thanks to its most impressive natural resource – offshore wind.

This resource will play an integral role in shaping Ireland’s green future, however, work is required to develop green hydrogen and distribution capabilities. 

Our offshore wind will generate electricity to fill our national grid and much more. We can use the extra electricity to power a process called electrolysis. This process separates the hydrogen found in ordinary water to produce a clean, green fuel – a key component of our future energy system.



As Ireland’s first green hydrogen company we are working hard to kick-start and grow Ireland’s hydrogen economy.

Our highly experienced, industry-leading team are collaborating with our technology and energy partners to move quickly and decisively towards helping Ireland achieve its climate action targets.



“Ireland is starting to take leadership in tackling climate change.

The production of hydrogen from excess wind capacity will play a significant role in Ireland’s decarbonisation, given that Ireland could be generating 8 GW of offshore wind by 2030.

There inevitably will be ‘curtailed’ energy that will go to waste unless we find ways of using it. EIH2 is planning the production of safe and environmentally-sound green hydrogen that will allow industry to decarbonise.

This initiative will create and sustain local jobs, and go a long way towards helping Ireland meet its international obligations on climate change.”



Passionate about climate action in green hydrogen


Hailing from a fishing family in Ballycotton in County Cork, Pearse knows the potential of Ireland’s abundant natural resource firsthand. 

It’s no secret he is highly motivated, with huge success in both corporate and personal business ventures.

Career highlights include becoming the youngest ever vice president to lead a corporate company and becoming president of Newbridge Network.  On joining, the company had a market cap of €2.4 billion and Pearse later sold it to Alcatel for nearly €12 billion.

Pearse decided he was experienced enough and could do his own thing and the story really begins there. He has had numerous successes in financial services, property, football, hospitality and now energy.

As well as EIH2, Pearse has also founded Green Rebel, which was established to service the future needs of offshore wind farms. The company acquired Crosshaven Boatyard in County Cork, which will serve as a base for the new operation to survey, equip and service a network of planned wind farms.

Pearse has invested €10 million of his own money into the project, including the purchase of two specially equipped, high tech ships and a survey plane, to service this emerging industry. 


Denis has more than 30 years of experience in a variety of senior and executive roles. He’s worked on numerous high-profile major projects including engineering and construction contracting in Europe, Middle East and Australia.

His experience also includes 20 years in the Energy sector including oil and gas, power and petrochemicals industries. In addition, Denis has gained experience working in commercial, utilities and infrastructure industries.

He has also held leadership positions within various business units covering project / site management, commercial, planning, estimating and proposals mainly within the Kentz Group and senior executive positions held in SNC Lavalin and Actavo.

Denis is equally comfortable leading company operations, managing complex engineering-led EPC projects, or major construction projects.

He is a committed, driven and passionate person, very respectful of clients, partners and colleagues, ethically valued, always puts safety first and will do the utmost to ensure positive leadership for the company and team.

Denis’ values always place employee’s welfare, the company’s reputation and performance as a priority.

Catherine Sheridan Hydrogen


Catherine’s focus is on energy system integration and the role for green hydrogen in supporting Ireland and Europe achieve Net Zero 2050. She sees green hydrogen as the missing link in addressing what the World Energy Council calls the energy trilemma. 

A chartered engineer and fellow of Engineers Ireland, she believes that collaboration and ambition are the secret sauce for Ireland’s energy transition.

She is on the board of Cork Chamber and a council member of Wind Energy Ireland and was recently recognised by the Hydrogen Economist as one of world’s top women in hydrogen.
