Hydrogean: Energean’s model that combines Eco-hydrogen production with carbon dioxide sequestration into the adjacent Prinos Carbon Capture & Storage plant.


Established in 2007, Energean is a London Premium Listed FTSE 250 (LSE: ENOG) and Tel Aviv  (TASE:אנאג) Listed E&P company with operations in eight countries across the Mediterranean and UK North Sea. Since IPO, Energean has grown to become the leading independent, gas-focused E&P company in the Eastern Mediterranean, with a strong production and development growth profile. The Company explores and invests in new ideas, concepts and solutions to produce and develop energy efficiently, at low cost and with a low carbon footprint. Energean's production comes mainly from the Abu Qir field in Egypt and fields in Southern Europe. The company's flagship project is the 3.5 Tcf Karish, Karish North and Tanin development, offshore Israel, where it intends to use the newbuild fully-owned FPSO Energean Power, which will be the only FPSO in the Eastern Mediterranean, to produce first gas, commencing mid-2022.With a strong track record of growing reserves and resources, Energean is focused on maximising production from its large-scale gas-focused portfolio to deliver material free cash flow and maximise total shareholder return in a sustainable way. ESG and health and safety are paramount to Energean; it aims to run safe and reliable operations, whilst targeting carbon-neutrality across its operations by 2050.

Objective Action

  • Contribution to the mitigation of the Climate Change phenomenon and cleaner air on Earth.
  • Protection of Earth’s atmosphere and ecosystem.
  • Taking decisive steps towards green and clean energy.
  • Alarming the oil and gas industry, as well as every industry, and setting a positive example to be followed on environmental issues.
  • Development and rise of environmental awareness on Climate Change and its consequences.
  • Initiatives and synergies with third parties developed by Energean for the protection of our atmosphere and the   environment in general (Partnerships for the Goals).
  • Be the first CCS plant and Eco-hydrogen hub in South East Europe.

Target Audience

  • Industries and electricity producers may take advantage of our CCS site while additional to that transportation, shipping, and domestic users may use our Eco-hydrogen production.
  • Current and future generations will benefit of Hydrogean. 


From 2021 until 2050+


Energean’s green technology approach is a combination of “Eco-H2” production - from mixtures of its own regionally sourced gas reserves, bio-gas and other non-recyclable wastes – with CO2 sequestration into adjacent underground gas storage facilities (Prinos CCS).  This process is designed to achieve negative CO2 emissions whilst stimulating the development of H2-based industries and transportation infrastructure and hence accelerating a move to local Green H2 production.

Eco-H2 is a novel combination of technically proven chemical processes that converts natural gas and untreated biogas into pure H2 and CO2. It has also the ability to incinerate non-recyclable wastes and organic compounds with energy recovery via oxy-combustion, leading to pressurized CO2 capture 99%+ efficiency simply by water condensation. No external power is needed and the requirements of potable water and land use are minimal. Production would be min. 40 tonnes/day of Eco-H2, equivalent to approx. 0,55 TWh H2/y or 14’000 ton H2/y.

Prinos CCS project refers to a Northern Greece CCS site which has been approved within the Greek RRF (Recovery and Resilience Fund) last Q2-2021, and is under Pre-FEED. It is anticipated the capture and storage to be 1 mln tonnes CO2/y for local Kavala area in operations within 2025 and after its expansion to be up to 2 million tonnes CO2/y with CO2 shipped by liquid CO2 carriers from remote “Hard-to-Abate” industrial sites.


Impact on Society

The clear, self-explanatory and apparent impact on society is the clean air and the mitigation of the Climate Change phenomenon.  It is one of our top priorities at Energean to protect the environment and minimize our impact on the planet. Our business model is based on contributing to meet the world’s growing energy needs in ways that are economically, environmentally and socially responsible. Our company embraces the values of sustainable development and has integrated energy and emissions efficient practices within all its activities, in order to deliver on our commitments in this regard. Our goal towards a net-zero emissions future aims towards a clean atmosphere for ourselves and the generations to come.
