The shift to a low-carbon EU economy raises the challenge of integrating renewable energy (RES) and cutting the CO2 emissions of energy intensive industries (EII). In this context, hydrogen produced from RES will contribute to decarbonize those industries, as feedstock/fuel/energy storage. MULTIPLHY thus aims to install, integrate and operate the world’s first high-temperature electrolyser (HTE) system in multi-megawatt-scale (~2.4 MW), at a chemical refinery in Salzbergen (DE) to produce hydrogen (≥ 60 kg/h) for the refinery’s processes. MULTIPLHY offers the unique opportunity to demonstrate the technological and industrial leadership of the EU in Solid Oxide Electrolyser Cell (SOEC) technology. With its rated electrical connection of ~3.5 MWel,AC,BOL, electrical rated nominal power of ~2.6 MWel,AC and a hydrogen production rate ≥ 670 Nm³/h, this HTE will cover ~40 % of the current average hydrogen demand of the chemical refinery. This leads to GHG emission reductions of ~8,000 tonnes during the planned minimum HTE operation time (16,000 h). MULTIPLHY’s electrical efficiency (85 %el,LHV) will be at least 20 % higher than efficiencies of low temperature electrolysers, enabling the cutting of operational costs and the reduction of the connected load at the refinery and hence the impact on the local power grid. A multidisciplinary consortium gathers NESTE (a Green Refiner as end-user), ENGIE (a global energy system integrator & operator), PaulWurth (Engineering Procurement Construction company for hydrogen processing units), Sunfire (HTE technology provider) and the world-class RTO CEA. They focus on operation under realistic conditions and market frameworks to enable the commercialisation of the HTE technology. By demonstrating reliable system operation with a proven availability of ≥ 98 %, complemented by a benchmark study for stacks in the 10 kW range, critical questions regarding durability, robustness, degradation as well as service and maintenance are addressed

HyCoFlex is aiming at the development of a retrofitable decarbonisation package for cogeneration of power and industrial heat with 100%-fired gas turbines. The solution will be integrated and fully demonstrated at an industrial site in Saillat-sur-Vienne in France. HyCoFlex will leverage on and further advance the infrastructure of a power-to-hydrogen-to-power industrial scale plant which was developed and demonstrated within the HYFLEXPOWER project. The project will develop operational flexibility capabilities and protocols to satisfy the typical operating profiles experienced by industrial cogeneration plants. By doing so, HyCoFlex will elaborate credible pathways for upscaling and replicating the retrofit package, ultimately accelerating the achievement of industrial and energy sector decarbonisation. In order to meet the global objective, within the HyCoFlex project, the HYFLEXPOWER plant concept and infrastructure will be implemented for 100% H2-fuelled cogeneration. In the framework of the project a Siemens Energy SGT-400 gas turbine will be upgraded with an advanced dry low-emission (DLE) H2 combustion system to operate with different natural gas / H2 fuel mixtures. The retrofitted demonstrator plant will be validated for flexible operation under various natural gas/hydrogen mixtures and loads, while aiming at overcoming state-of-the-art efficiencies with decreased NOx emissions. Finally, HyCoFlex will explore pathways for upscaling and commercialization of decarbonised power generation from gas turbines within a circular-economy framework.

Clean, reliable and secure energy supply is a key requirement for the further development of the European economy. At the same time, the Paris Agreement and its aim to limit the global warming to well below 2°C call for a quick and significant reduction of CO2 emissions, including the energy sector. In the energy sector this can only be achieved by a significant increase of the share of renewable energy sources (RES). As the most abundant RES, wind and solar, are intermittent by nature, there is a need for energy storage technologies, to provide back-up power when wind and solar output are low and more generally for load levelling and grid stabilisation. Chemical storage appears to be the most promising long-term energy storage technology. Among chemical storage technologies, hydrogen is expected to dominate as it can be produced by electrolysis of water using excess energy from RES, easily compressed and stored, and finally re-electrified using gas turbines. The goal of HYFLEXPOWER is the first-ever demons

There is a strong demand from EU to decarbonise freight transport. RHeaDHy will contribute to this by developing high-performance hydrogen (H2) refuelling stations. RHeaDHy aims at fully implement and validate new refuelling protocols that will allow to refuel 100kg H2 trucks in 1Omin. Partners will design and assembly a new very high flow refuelling line for 700bar H2 truck. To do so, they will develop missing key components needed to reach the mean flow target of 170g/s (300g/s at peak). The unique RHeaDHy comprehensive approach will guaranty an optimal design of components and refuelling line by gathering in the consortium best-in-class partners manufacturing all the components downstream high-pressure refuelling station storage to vehicle storage. This approach will allow to choose the optimal trade-off on constrains repartition among components and to fully consider vision of real vehicle constrains. New implemented refuelling protocols are based on previous work (PRHYDE) and standardization committee work, and involve calculation of refuelling coefficients specific to vehicle storage that need to be derived from hundreds of simulations. This extensive simulation work will be performed on refuelling model validated in previous European projects. To dedicate at least 1.5 years to an extensive test campaign, components and refuelling line design, manufacturing and assembly will be achieved within 2 years. 2 refuelling stations will be installed in France and Germany within the first 2.5 years. 2 truck storage test systems will be used to test and validate refuelling protocols on full scale storage. This work will allow to provide feedback from the field to significantly contribute to the establishment of standards on refuelling interface components and protocols. RHeaDHy will then represent a significant step forward to unlock H2 truck market by allowing wide and performant refuelling station network based on European alternative fuel infrastructures ambition.

GREENH2ATLANTIC will help Europe to reach green and affordable electrolysis at GW-scale in 2030 by developing and demonstrating a first-of-a-kind 100 MW alkaline electrolyser at TRL8, leveraging scale-up, standardization and manufacturing automation. This 100 MW electrolyser will be composed of innovative, scalable and fast-cycling 8 MW modules which overcome bottlenecks related to CAPEX (480EUR/kW, -31%), efficiency (49 kWh/kg at nominal power), size (-40%), lifetime (70 000 operating hours @ degradation rate of 0.12%/1000h), current-density (>0.5 A/cm2) and flexibility (ramp-up and down between 20-100% in less than 30 sec and 5 sec, respectively). GREENH2ATLANTIC will supply multiple local off-takers and help reduce the LCOH to 2.87EUR/kg of green H2. An innovative interface system composed of advanced power electronics will allow for the direct coupling of the electrolyser with local, dedicated hybrid (solar and wind) renewable energy. Moreover, an innovative, AI-enhanced Advanced Hydrogen Management System will allow for the optimization of OPEX, load factor, real-time H2 production management, system behaviour analysis, etc. The consortium includes the full value chain including European electrolyser manufacturing, green hydrogen production, off-takers from the chemical industry and natural gas grids, power electronics developers, AI energy management system developers, renewable energy providers and electrical grid balancing. The demonstrator will reduce greenhouse gas emissions by 82.16 ktCO2-eq/year. Clear exploitation and replication plans based on rigorous analyses are presented to reach 1 GW by 2030 in Sines and beyond, creating an estimated 1147 direct and 2744 indirect jobs. Green H2 market readiness will be enhanced in promising H2 valleys across Europe, targeting at least 5 systemic H2+RE investment plans facilitated across Europe by the end of the project. Finally, the project will provide actionable input for EU harmonisation and regulations.
