    Air Liquide & TotalEnergies to Produce Hydrogen at Grandpuits

    Strategic Research Institute
    Published on :
    1 Dec, 2022, 4:30 am

    Air Liquide and TotalEnergies are innovating, in the context of the conversion to a biorefinery of the TotalEnergies’ Grandpuits site, to produce and valorize renewable and low-carbon hydrogen. Under a long-term contract, committing TotalEnergies to purchase the hydrogen produced for the needs of its platform, Air Liquide will invest over 130 million euros in the construction and operation of a new unit producing hydrogen. This unit will partly use biogas from the biorefinery built by TotalEnergies, and will be delivered with Air Liquide’s carbon capture technology, CryocapTM. These innovations will prevent emissions amounting to 150,000 tonnes of CO2 a year compared to current processes. TotalEnergies’ biorefinery will use the unit’s hydrogen to produce sustainable aviation fuel.

    Air Liquide will build and operate at the Grandpuits site a new hydrogen production unit with an annual capacity of more than 20,000 tonnes. By recycling, in part, residual biogases from Grandpuits’ biorefinery as a substitute for the natural gas traditionally used, the hydrogen produced by this unit will be partly renewable.

    In addition, this unit will include, from its start-up, an Air Liquide Cryocap H2 carbon capture unit. This will enable to capture, for reuse in agri-food and industrial applications, over 110,000 tonnes of CO2 per year contributing to reducing the site’s carbon footprint.

    Most of the renewable and low-carbon hydrogen produced will be used by the biorefinery to produce sustainable aviation fuel. This hydrogen could also be used to support sustainable mobility in the Ile-de-France region.

    Commissioned in 1966, Total's Grandpuits-Bailly-Carrois refinery was for a long time the only refinery in the Paris region. In September 2020, TotalEnergies launched a project to convert the site, in line with its strategy to become carbon neutral by 2050. This zero-crude project, with a total investment of more than 500 million euros, is based on the development of several future-oriented activities in the field of biomass, renewable energies, and circular economy: chemical recycling of plastic waste, production of biosourced and biodegradable bioplastics, production of sustainable aviation fuels, construction of a solar farm and electricity storage by batteries. The start-up of these new units will begin in 2022, and they should all be operational by 2025.

    H3 Dynamics Tests Flight with Hydrogen Electric Nacelle

    Strategic Research Institute
    Published on :
    1 Dec, 2022, 4:30 am

    The future of hydrogen aviation powered by H3 Dynamics’ distributed hydrogen propulsion nacelles has taken flight for the very first time in France. H3 Dynamics’ 25kg test aircraft is already a breakthrough, with an electric flight range of up to 900km on liquid hydrogen, or 350km with pressurized hydrogen. Its externalized nacelle design also frees up 30L of fuselage volume with no hydrogen nor any powertrain elements inside. H3 Dynamics’ hydrogen propulsion nacelles could potentially become a “snap-on” retrofit for battery-powered unmanned eVTOL or fixed wing cargo drones.

    Preparing for the arrival of much longer duration unmanned hydrogen flights - H3 Dynamics started to work on airspace safety with world-leading air traffic control companies. It has been building experience with high-volume enterprise data services being deployed in smart cities such as Singapore, and gradually coupling these with drone-agnostic charging stations.

    By starting at the lower-end boundary of regulatory and certification efforts, H3 Dynamics doesn’t need to wait until 2035 to begin its commercial journey.

    Now H3 Dynamics is already preparing its next steps.

    It is exploring liquid hydrogen integration as part of a joint-development with ISAE-SUPAERO in Toulouse launched in 2019. The objective is a historical and symbolic Atlantic crossing on hydrogen electric propulsion in the coming two years.

    And with airfield experiments feeding its digital twin capability for hydrogen aircraft design, H3 Dynamics is now working on a next generation platform powered by 6 independent hydrogen-electric nacelle systems. The aircraft will feature fast-refueling and will be used as a test bed for H3 Dynamics hydrogen-electric propulsion technology moving forward.

    Other, higher-visibility hydrogen aircraft proponents will fly larger size aircraft much sooner – but they will do so by converting existing aircraft using fuel cells sourced from the automotive world – and storing large amounts of gas or liquid hydrogen inside the main fuselage.

    Supported by their converging visions of the future, Nantes Saint Nazaire Port and Lhyfe have naturally chosen to combine their efforts and areas of expertise in order to identify, to understand and to assess the condition’s for the establishment of a supply chain associated with offshore hydrogen production.

    This collaboration is intended to identify the port areas and facilities capable of accommodating R&D prototypes and being utilized to try out innovative solutions. The partnership also focusses on the identification of the industrial requirements involved in the construction of the equipment to be used to produce offshore hydrogen on a mass scale, and on the port infrastructures necessary for the production, launching and integration of those future items of equipment. Lastly, the two parties will deliberate together on how best to bring ashore the renewable hydrogen mass-produced at sea, so as to define the requisite industrial and logistical requirements for the reception and injection of the gas into the land-based network.

    At the end of September in the Saint Nazaire dock basins, Lhyfe launched its Sealhyfe project to deliver the world’s first offshore renewable hydrogen production prototype, which will have a capacity of 1 MW and will be connected to a floating wind turbine.

    Lhyfe already operates a renewable hydrogen production facility employing water electrolysis, and is planning to set up similar onshore facilities throughout Europe. The Company is considering the idea of developing and operating offshore renewable hydrogen production platforms on existing fixed structures or on fixed-position or floating foundations, and is ramping up its research and development investments for the development of offshore renewable hydrogen production as close as possible to offshore energy sources. By 2030-2035, the offshore sector could represent additional installed capacity of the order of 3 GW for Lhyfe.

    Lochem heeft primeur van eerste met waterstof verwarmde huizen
    Artikel van ANP Producties • Gisteren om 14:47
    © ANP

    LOCHEM (ANP) - In de Gelderse plaats Lochem worden voor het eerst bewoonde woningen verwarmd met behulp van waterstof, meldt netwerkbeheerder Alliander. Samen met de bewoners en andere partijen werkte het netwerkbedrijf aan aanpassingen die het mogelijk maakten waterstof door bestaande aardgasleidingen te pompen.

    Het gaat om het eerste Nederlandse experiment met waterstof in de bebouwde omgeving, dat pas van start kon gaan na toestemming van het Staatstoezicht op de Mijnen. Doel van het proefproject is ervaring opdoen met het hergebruik van bestaande gasnetten voor het leveren van waterstof. Daarvoor bouwden betrokken partijen onder andere een installatie in Lochem die de waterstof in het aardgasnetwerk zal voeden.

    Uiterlijk in 2050 moeten alle Nederlandse woningen en bedrijfspanden van het aardgas af. Volgens Daan Schut, bij Alliander leidinggevende voor de energietransitie, zijn alternatieve gassen als waterstof belangrijk voor het verduurzamen van de energievoorziening. Bij de verbranding van waterstof komt geen CO2 vrij en het gas is in theorie met duurzaam opgewekte elektriciteit te produceren. "Met elektriciteit alleen, redden we het niet", aldus Schut. Voor moeilijk te isoleren woningen waar een elektrische warmtepomp weinig uithaalt zou waterstof bijvoorbeeld uitkomst kunnen bieden.

    Grijze waterstof

    Echt duurzaam is de waterstof die nu door de Lochemse gasleidingen stroom overigens niet. Het gaat om zogeheten grijze waterstof, waarvoor bij de productie aardgas is gebruikt en dus alsnog CO2 vrijkomt. Leverancier Westfalen Gassen Nederland is wel van plan in de toekomst 'groene' waterstof te leveren, die uitsluitend met duurzame elektriciteit is gemaakt. Maar op dit moment wordt er nog te weinig groene waterstof geproduceerd om er huizen mee te verwarmen.

    Een andere kanttekening die milieuorganisaties, waaronder Milieudefensie, maken heeft te maken met het verlies van energie bij het produceren van waterstof. Er gaat bij het omzetten van elektriciteit in waterstof heel wat energie verloren.

    Shell doet onderzoek naar productie waterstof met kernenergie
    Shell gaat samen met het Amerikaanse NuScale Power en andere industriële bedrijven werken aan een kleine kernreactor die waterstof maakt. De bedrijven hebben daarover een samenwerkingsovereenkomst ondertekend.

    NuScale heeft een kleine kernreactor ontwikkeld, een zogenoemde small-modular-reactor. Het is tot nu toe het enige bedrijf in de VS dat goedkeuring heeft van de Amerikaanse overheid voor zijn ontwerp. Shell is geïnteresseerd in de technologie omdat die het mogelijk kan maken goedkoop waterstof te produceren zonder dat daarbij CO2 vrijkomt. Shell is grootverbruiker van waterstof in onder andere zijn raffinaderijen. Die waterstof wordt nu nog gemaakt met aardgas. Daar komt CO2 bij vrij.


    Naast de productie van waterstof onderzoekt NuScale ook de mogelijkheid om met kleine kerncentrales een bijdrage te leveren aan het stabiel houden van het elektriciteitsnet.

    Als in de toekomst een hoog percentage van alle stroom uit weerafhankelijke energiebronnen komt, moet er een oplossing worden gevonden voor de periodes zonder wind of zon. Waterstof zou een rol kunnen spelen als opslagbron van energie, die weer kan worden omgezet in elektriciteit als de vraag op windluwe donkere dagen hoog is.

    Een rare proef: kerncentrales maken geen waterstof, maar stroom en met stroom kun je waterstof maken.
    Deze proef is dus volkomen overbodig.

    BMW Starts Production of Hydrogen-Powered Model

    Strategic Research Institute
    Published on :
    5 Dec, 2022, 4:42 am

    The BMW Group is commencing production of its BMW iX5 Hydrogen model. Manufacture of the small-series hydrogen-powered vehicle is taking place in the pilot plant at its Munich Research and Innovation Centre FIZ. The first ever Sports Activity Vehicle featuring hydrogen fuel cell technology has already completed an intensive programme of testing under demanding conditions during the development phase and will now be used as a technology demonstrator for locally carbon-free mobility in selected regions from spring 2023.

    The BMW iX5 Hydrogen is being built in the BMW Group’s pilot plant at its Research and Innovation Centre in Munich. This is the interface between development and production where every new model from one of the company’s brands is made for the first time. Around 900 people work there in the body shop, assembly, model engineering, concept vehicle construction and additive manufacturing. They each work on up to six vehicle projects simultaneously and are tasked with ensuring that both the product and the manufacturing process are ready for series production. In the case of the BMW iX5 Hydrogen, specialists in hydrogen technology, vehicle development and initial assembly of new models have been working closely together to integrate the cutting-edge drive and energy storage technology.

    BMW Group Plant Spartanburg in the USA supplies the base vehicles for the hydrogen model, which has been developed on the platform of the BMW X5. They are fitted with a new floor assembly in the pilot plant’s body shop that makes it possible to accommodate the two hydrogen tanks in the centre tunnel and under the rear seat unit. The model-specific 12V and 400V electrical systems, high-performance battery, electric motor and fuel cell are all integrated during the assembly stage, alongside standard production parts. Positioned in the rear axle area together with the high-performance battery, the electric motor is a product of the current, fifth-generation BMW eDrive technology also employed in battery electric and plug-in hybrid models from BMW. The fuel cell systems located under the bonnet of the BMW iX5 Hydrogen have been manufactured at BMW’s in-house competence centre for hydrogen in Garching to the north of Munich since August this year.

    The BMW iX5 Hydrogen combines all the benefits of a locally emission-free drive system with outstanding everyday usability and long-distance capabilities. This makes its hydrogen fuel cell technology an attractive complementary alternative to the battery electric drive system. This is especially true for customers for whom short refuelling stops and long ranges are a must, as well as for regions still lacking an adequate charging infrastructure.

    Rolls-Royce & easyJet Set Milestone for Hydrogen Aircraft

    Strategic Research Institute
    Published on :
    5 Dec, 2022, 4:44 am

    Rolls-Royce and easyJet have set a new aviation milestone with the world’s first run of a modern aero engine on hydrogen. The ground test was conducted on an early concept demonstrator using green hydrogen created by wind and tidal power. It marks a major step towards proving that hydrogen could be a zero carbon aviation fuel of the future and is a key proof point in the decarbonisation strategies of both Rolls-Royce and easyJet.

    Both companies have set out to prove that hydrogen can safely and efficiently deliver power for civil aero engines and are already planning a second set of tests, with a longer-term ambition to carry out flight tests.

    The test took place at an outdoor test facility at MoD Boscombe Down, UK, using a converted Rolls-Royce AE 2100-A regional aircraft engine. Green hydrogen for the tests was supplied by EMEC (European Marine Energy Centre), generated using renewable energy at their hydrogen production and tidal test facility on Eday in the Orkney Islands, UK.

    Following analysis of this early concept ground test, the partnership plans a series of further rig tests leading up to a full-scale ground test of a Rolls-Royce Pearl 15 jet engine.

    The partnership is inspired by the global, UN-backed Race to Zero campaign that both companies have signed up to, committing to achieve net zero carbon emissions by 2050.

    Airbus Reveals Hydrogen-Powered Zero-Emission Engine

    Strategic Research Institute
    Published on :
    5 Dec, 2022, 4:45 am

    Airbus has revealed that it is developing a hydrogen-powered fuel cell engine. The propulsion system is being considered as one of the potential solutions to equip its zero-emission aircraft that will enter service by 2035.

    Airbus will start ground and flight testing this fuel cell engine architecture onboard its ZEROe demonstrator aircraft towards the middle of the decade. The A380 MSN1 flight test aircraft for new hydrogen technologies is currently being modified to carry liquid hydrogen tanks and their associated distribution systems.

    Airbus identified hydrogen as one of the most promising alternatives to power a zero-emission aircraft, because it emits no carbon dioxide when generated from renewable energy, with water being its most significant by-products. There are two ways hydrogen can be used as a power source for aircraft propulsion. First via hydrogen combustion in a gas turbine, second, by using fuel cells to convert hydrogen into electricity in order to power a propeller engine. A hydrogen gas turbine can also be coupled with fuel cells instead of batteries in a hybrid-electric architecture.

    Hydrogen fuel cells, especially when stacked together, increase their power output allowing scalability. In addition, an engine powered by hydrogen fuel cells produces zero NOx emissions or contrails thereby offering additional decarbonisation benefits.

    Airbus has been exploring the possibilities of fuel cell propulsion systems for aviation for some time. In October 2020, Airbus created Aerostack, a joint venture with ElringKlinger, a company with over 20 years of experience as both a fuel cell systems and component supplier. In December 2020, Airbus presented its pod-concept which included six removable fuel cell propeller propulsion systems.

    Nikola Corporation announced that the Department of Energy Loan Program Office has invited its Phoenix Hydrogen Hub project loan application into Part II of its application process. The project loan application was submitted on May 26, 2022, and has now progressed through the Part I review.

    The application for a loan guarantee under the Innovative Clean Energy projects solicitation could amount to up to $1.3 billion for a renewable electrolytic hydrogen production facility that could produce up to 150 metric-tons of hydrogen per day. The application process is wholly dependent on the results of the Department of Energy review and evaluation of a Part II Application, and DOE’s determination whether to proceed.

    The Phoenix Hydrogen Hub LLC owns 920-acres of undeveloped land in Maricopa County, Ariz. where the facility is planned to be sited to support the deployment of Nikola’s heavy duty, zero-emission fuel cell electric vehicles and hydrogen refueling stations in California and the US Southwest.

    The hub is expected to be built in phases to scale with the demand created from Nikola’s zero-emission trucks, starting with 30 metric-tons, and expanding up to 150 metric-tons of hydrogen per day, with expansion potential as the demand for clean hydrogen in the region expands. Construction of the first phase is anticipated to be completed in 2024, once final investment decisions and customary regulatory approvals are finalized.

    Global energy consultancy Xodus is architecting a new green hydrogen project based in the Mid-West region of Western Australia which will scale up to 1000 MW of electrolyser capacity. MercurHy is an export scale project which aims to supply green hydrogen whilst leveraging economies of scale, particularly regarding the supply and purchase of renewable energy. Investor engagement is underway as the company targets equity funding for the project from experienced capital and infrastructure partners interested in commercial green hydrogen progressing.

    The project provides for a total electrolyser capacity of 1000 MW being installed over three phases: 150 MW in Phase 1; 500 MW in Phase 2; and 1000 MW by the end of Phase 3. The intent behind scaling the project in this way is two-fold, initially to allow the market for green hydrogen sufficient time to develop and then to capitalise on future electrolyser price reductions.

    Xodus continues to progress the commercial strategy for the project, having entered into a memorandum of understanding for hydrogen supply with ASX-listed VRX Silica, a company with long-life, high-quality silica sand projects in Western Australia and plans for the manufacture of solar panels locally to supply national and international demand. Xodus has also advanced discussions with other potential offtakers and has the support of local landowners and the Western Australian government.

    Led-lampen winnen waterstof uit ammoniak
    Artikel van admin • 2 uur geleden

    Waterstof is een veelbelovende, emmissieloze brandstof. Maar waterstof transporteren is ingewikkeld en duur. Waterstofmoleculen verpakt in ammoniak van A naar B verplaatsen is daarentegen een stuk eenvoudiger. Een nieuwe techniek die led-licht gebruikt voor het omzetten van ammoniak in waterstof, kan daarom belangrijk zijn voor de uitrol van de waterstofeconomie.

    Met felle led-lampen wordt ammoniak omgezet in waterstof | Credit: Brandon Martin / Rice University

    Onderzoekers van de Amerikaanse Rice University hebben een techniek ontwikkeld die led-licht gebruikt om ammoniak om te zetten in waterstof. Met betaalbare en makkelijk verkrijgbare grondstoffen is een systeem gebouwd dat goedkoper, efficiënter, en op meer plekken toepasbaar belooft te zijn dan bestaande technieken om van ammoniak waterstof te maken.

    In een paper dat deze week in het vooraanstaande wetenschappelijke tijdschrift Science is gepubliceerd, schrijven de wetenschappers dat ze een katalysator – een versneller van chemische reacties – hebben ontworpen die in plaats van op hitte, op licht werkt.

    Geen hitte, maar licht
    Waar bestaande thermochemische installaties ammoniak (NH3) op temperaturen van vele honderden graden laten uiteenvallen in drie waterstofmoleculen (H) en één stikstofmolecuul (N), is het de wetenschappers gelukt dit te doen zonder die extreme hitte, maar met gigantisch felle led-lampen. In theorie is dit een stuk duurzamer, aangezien de huidige installaties met aardgas of olie tot hoge temperaturen worden opgestookt.

    Lennart van der Burg, waterstofexpert bij onderzoeksinstituut TNO, legt uit dat het principe dat de wetenschappers gebruiken, photokatalyse wordt genoemd, licht-katalyse dus. Hij vindt het een interessante ontwikkeling. “Je hebt veel minder schaarse materialen nodig, het is energie-efficiënt omdat het op lage temperaturen werkt en de techniek kan op kleine schaal worden toegepast in modulaire reactoren”, zegt hij.

    De techniek kan op licht in plaats van hitte werken door slim gebruik te maken van koper en ijzer. Op nano-schaal hebben de onderzoekers met ijzer- en kopermoleculen zogenaamde ‘antenne-reactoren’ in elkaar gezet die sterk op licht reageren en zo de omzetting van ammoniak in waterstof versnellen. Normale reactoren werken met veel duurdere en zeldzamere materialen zoals ruthenium, een metaal dat tot de platinagroep behoort.

    Toepassingen op kleine schaal
    Het nieuwe type reactor belooft op kleine schaal te kunnen worden toegepast. Van der Burg denkt dat het mogelijk is om de reactoren bijvoorbeeld op lange-afstandsschepen te installeren. Die zouden ammoniak ter plekke kunnen omzetten in waterstof om hun motor of brandstofcel op te laten draaien. Aan de andere kant wordt er ook gewerkt aan brandstofcellen die direct op ammonia werken, waarmee de extra stap terug naar waterstof overbodig wordt. “Voor elke toepassing van waterstof moet je naar de hele keten kijken, en bedenken welke manier van transport en gebruik het meest geschikt is.”

    Maar, benadrukt Van der Burg, het kan zomaar nog tien tot vijftien jaar duren voordat we deze technologie in de praktijk terug gaan zien. “De onderzoekers werken nu nog op de vierkante centimeterschaal. Ze produceren enkele grammen waterstof”, vertelt hij. “Er zijn tientallen jaren lang miljarden geïnvesteerd in huidige thermochemische technieken. Het is niet gek dat het ontwikkelen van een heel nieuw principe veel tijd kost. Maar dat is geen reden om op je handen te gaan zitten. De uitdaging is juist om dergelijke ontwikkelingen te versnellen.”
