ITEG will develop and validate an integrated tidal energy and hydrogen production solution for clean energy generation to be demonstrated in Orkney. The project addresses energy related carbon emissions in North West Europe and will tackle grid export limitations faced in remote communities.
Led by the European Marine Energy Centre (EMEC) in Orkney, the ITEG project brings together partners from across the UK, France, Belgium and the Netherlands and will adopt three low carbon technologies (tidal turbine, electrolyser and Energy Management System)
The cost of pre-commercial demonstration for ocean energy is high and investors are reluctant to invest until the technology has been proven in the sea at scale. ITEG sets out to drive down these costs through the development of an integrated hydrogen production solution.
The integrated solution combines Orbital's next generation 2 MW floating tidal energy converter, the Orbital O2, with EMEC's 670 kW electrolyser and an onshore energy management system (EMS) at EMEC's onshore hydrogen production site on the Orkney island of Eday.
Initially due to complete in December 2022, ITEG received an approved project modification which will see the project run until September 2023.
In a context of global supply chain issues, the 0.5 MW hydrogen electrolyser initially scoped for ITEG could not be delivered by partner Elogen within the timeframe of the project. Elogen remains an active partner within the consortium and, as such, will support the production of valuable documentation on topics including lessons learned during manufacture, technological advances and scalability of electrolysers.
The updated combined tidal and hydrogen solution will use power generated by the Orbital O2, which was deployed at the Fall of Warness in 2021, to demonstrate hydrogen production from tidal energy using EMEC’s 670kW electrolyser with a smart onshore energy management system (EMS).
A recent vanadium flow battery installation on EMEC’s site will also be incorporated into the demonstration ‘to smooth’ the tidal power output and optimise hydrogen production.
The EMS system will enable EMEC to control whether the tidal power generated is fed into the national grid, directly into the electrolyser to produce hydrogen or into the battery to be stored and used at a later date.
The following graphic shows how the three low carbon technologies will form an integrated hydrogen production solution;

With a view to 2050, the European Commission is also putting forward renewable hydrogen as a sustainable energy source. This thematic seminar will guide you through the latest market and technology trends. We’re specifically focusing on the marriage of offshore energy, such as offshore wind energy in combination with the production of green hydrogen.
Hydrogen is an important part of the European Green Deal. The development of renewable hydrogen based on wind and solar energy is a priority for the European Commission. The aim is to decarbonise the production of hydrogen.
The increasing production of offshore wind energy in Europe, in addition to other forms of energy production at sea that are still in full development, offer numerous opportunities to combine and integrate electrolysis. The use of hydrogen will gradually be introduced in various industrial sectors, including the offshore sector.

Hydrogen is now a fundamental pillar of energy policy of the EU as it transitions to a net zero future. It is a key component of the EU Strategy for Energy System Integration and has been included in the TEN-E framework. To unlock hydrogen’s benefits the EU hydrogen strategy5 targets 6 GW of electrolyser by 2024 and 40 GW by 2040, with heavy-duty transport identified as a key sector.
Globally, Governments are recognising the hydrogen opportunity and need for government support and have implemented hydrogen strategies whilst others are developing ambitious hydrogen plans.
Hydrogen is the catalyst driving Europe’s energy transition. Optimising this journey delivering SMARTH2 through valorisation of the hydrogen supply chain, production, storage and use to meet future need is key to creating a successful hydrogen Europe.
Webinar #4 in the GenComm SMARTH2 series on May 18, 2021 will examine how countries are scaling up and optimising production from additional green energy resources to meet current demand and opening new avenues of generation for utilisation.
The series of webinars will run from 10th March through to 27th May and will cover such topics as hydrogen optimisation, supply, infrastructure & storage, demand & use and stakeholder engagement.

Abstract:
“This paper presents the modeling and the simulation of a hybrid marine current-hydrogen power generation system. The marine current power generation system consists of a fixed pitch marine current turbine directly coupled to a permanent magnet synchronous generator (PMSG). The generator is connected to a DC link capacitor via a controlled rectifier, which has two modes of operation. The first mode is the maximum power point tracking (MPPT) by using torque control when the generator runs below the rated speed. The second mode is the power limitation (at the rated value) when the generator runs above the nominal speed. The generated power is transferred from the DC-link to the load via an inverter to run the system in a stand-alone operation mode. An energy storage system must cover the difference between the generation and the consumption for this scheme. The hydrogen, compared with the different energy storage systems, exhibits characteristics more applicable for marine current power generation systems. When the generated power is higher than the load requirements, a Megawatt-scale proton exchange membrane (PEM) electrolyzer consumes the surplus energy for hydrogen generation. The generated hydrogen is stored in tanks to feed a PEM fuel cell system to generate power in case of shortage. Based on this topology and operation procedure, the overall system is called an active power generation system. The MW scale PEM electrolyzer model is presented based on state of the art and the literature of different scales PEM electrolyzer system modeling”.

Abstract:
“This paper presents the decentralized JADE (Java Agent Development Environment) based Multi-Agent System (MAS) oriented to the energy management and balance of the hybrid marine-hydrogen power generation system. The proposed hybrid marine-hydrogen system consists of a fixed pitch direct drive tidal turbine, a MegaWatt (MW) scale proton exchange membrane electrolyzer, and fuel cell and a Li-ion battery stack. The different components are coupled together on a DC-link via different topologies of power electronics converters for feeding a residential load as isolated system architecture. The MW scale electrolyzer and fuel cell systems represent the main elements of the hydrogen energy storage system. An isolated mode of operation is programmed to evaluate the MAS capability of energy management and balance considering the marine current intermittency and the demand-side variations. The proposed energy management system considers the safe operations of the electrolyzers, fuel cell and battery by considering their constraints and dynamics.”

Abstract:
“The study deals with the techno-enviro-economic aspects of hydrogen production using polymer electrolyte membrane electrolysers powered by a hybrid grid-connected tidal-wind energy system. System modelling is presented initially. The energy management strategies for hydrogen production are then analysed as rule-based approach and as optimised approach. An objective function to maximise the operating profit under optimal system operation is formulated considering the variable energy costs, capital and maintenance expenditure, and real system constraints. A comprehensive cost analysis of the system is obtained by comparing two different optimisation approaches based on fixed cost and levelised cost factors, respectively. Towards reaching this goal, the use of mixed integer genetic algorithm optimisation is investigated. The operation of electrolyser in terms of its different operating modes, namely stop, running, and stand-by is presented. The dynamic optimisation of an electrolyser capable of working at up to twice its nominal rating for a limited duration is also analysed in the study. The results of the optimisation approach are 41.5% and 47% higher than the rule-based approach in terms of the annualised profit and carbon emission savings, respectively. In addition, the recurrent switching of electrolyser unit operating modes is avoided with the optimisation approach, reducing the associated energy consumption of about 27.2 MWh annually. The proposed model can be used as a generic tool for hydrogen production analysis under different contexts and it is especially applicable in high green energy potential sites with constrained grid facilities.”

Abstract:
The main challenges for renewable energy integration in electrical grid system are their variability and prediction. Tidal renewable energy is considered low variability in comparison to wind energy generation and due to tides regular periodicity, it is often quoted as predictable. This paper presents the modeling of Orkney's distribution network with the integration of tidal energy. This multi-physics model is based on the graphical formalism tool, Energetic Macroscopic Representation (EMR). This tool has been used to analyze the Tidal energy conversion (TEC) system based on the behavior of permanent magnet synchronous machine (PMSM). The daily, monthly and yearly variations of marine water speed in Orkney were observed. The EMR has been efficiently used in the representation of Orkney energy system integration of Orbital O2 tidal systems, and showing its effectiveness to adopt the control strategy. More precisely, the data of current water profile for 2009 has been chosen from 10 years big data to test the adopted deduced control technique. The methodology of this tool is described in details and the simulation results obtained in MATLAB environment are presented.
