Inleiding en samenvatting

Het project ‘herinrichting Willemspolder fase 1 van Dekker Groep beoogt delfstoffenwinning mogelijk te maken in de Willemspolder. De Willemspolder vormt een uiterwaard rond de Waal: samen met de Gouverneurspolder maakt de Willemspolder deel uit van de Midden-Waal. Voor fase 1 loopt het plangebied vanaf de Nieuweweg in IJzendoorn tot circa 500 m voor de Prins Willem-Alexanderbrug in Echteld. Met het herinrichting Willemspolder fase 1 wordt het gebied ingericht voor hoogwaterveiligheid, natuurontwikkeling, recreatie, landschapsinrichting, duurzaamheid en mobiliteit. In het kader van hun duurzaamheidsambities onderzoekt Dekker de mogelijkheid tot waterstofproductie dan wel de op- en overslag van waterstof in een vloeibaar medium als brandstof van de binnenvaartschepen. De opslag en het transport van waterstof onder druk brengt risico’s met zich mee: bij lekkage van waterstof ontstaat het gevaar van brand en explosie. We hebben voor de productie van waterstof deze gevaren inzichtelijk gemaakt door middel van een berekening met het wettelijk voorgeschreven Safeti versie 8.2. In deze notitie zijn deze risico’s indicatief beschouwd voor een beoordeling van het aspect externe veiligheid ten gevolge van het gebruik van waterstof. Het is een indicatieve beoordeling omdat de exacte uitvoering van de installatie is nog niet bekend is.

Deze notitie dient als onderdeel van de milieueffectrapportage voor de herinrichting van Willemspolder fase 1. In hoofdstuk 2 is een situatieschets (proces) en het wettelijk kader kort beschreven. Hoofdstuk bevat de uitgangspunten voor het rekenmodel. Hoofdstuk 4 geeft de resultaten. De interne afstanden binnen het tankstation volgens een concept-richtlijn zijn opgenomen in hoofdstuk 5. Hoofdstuk 6 bevat de conclusies. 0,00

Het bepalende plaatsgebonden risico (rode contour) omvat geen objecten en voldoet aan het beleid. Het groepsrisico is verwaarloosbaar Uit de indicatieve beoordeling blijkt dat waterstofproductie dan wel de op- en overslag van waterstof in een vloeibaar medium als brandstof van de binnenvaartschepen door de Dekker Groep relatief laag is en toelaatbaar is volgens het beleid en wet- en regelgeving. Vanuit de regelgeving voor externe veiligheid zijn er vooralsnog geen juridische belemmeringen. In een vervolgstadium (bij uitwerking van de plannen) zal getoetst moeten worden aan de drempelwaarde voor Brzo-inrichting en de BBT-conclusies en PGS-35-richtlijn.

Situatieschets

2.1

Het plan: productie van waterstof

Als uitgangssituatie zijn we uitgegaan van het voorlopige plan voor waterstofproductie “inpassing LOHC” van Dekker groep (bijlage I). In het kort is het plan: Waterstofgas wordt in een electrolyzer geproduceerd door water te splitsen: hierbij ontstaat waterstof en zuurstof. Het waterstof wordt in tijdelijke vorm opgeslagen in twee buffer vatten. Deze buffer vaten zijn stalen tanks van 40 nm 3 met een druk van 30 bar. In totaal kan er 200 tot 400 kg waterstofgas worden opgeslagen in deze tanks. Het waterstof wordt vervolgens gebonden aan een vloeistof, de zogenaamde LOHC (Liquid Organic Hydrogen Carrier). Dit is een waterstofarme organische vloeistof die nauwelijks ontvlambaar is (nadere specificaties niet bij ons bekend). De binding gebeurt bij een temperatuur van 150 – 300 graden Celcius en een druk van 70 – 80 bar. Na binding van de LOHC met het waterstof kan het waterstofrijke medium op atmosferische druk en temperatuur worden opgeslagen in bufferinstallaties. Vanuit die bufferinstallaties kunnen binnenvaartschepen het LOHC-waterstof mengsel tanken. Op het waterstofschip zit een installatie die de waterstof uit de LOHC onttrekt, waardoor elektriciteit vrijkomt. Het waterstof-arme LOHC kan worden teruggepomt naar de bufferinstallatie op de kade, waar het hergebruikt kan worden als medium voor waterbinding. In Figuur 1 is het proces weergegeven.

2.2

Wettelijk kader

De opslag en productie van waterstof valt onder het Activiteitenbesluit Milieubeheer en Besluit externe veiligheid inrichtingen. Daarbij is de PGS35 richtlijn van toepassing: Waterstofinstallaties voor het afleveren van waterstof aan voertuigen en werktuigen. Bij de opslag en productie van meer dan 5 ton waterstof per jaar valt de inrichting ook onder het Besluit risico’s zware ongevallen. Volgens de Seveso III-richtlijn, bijlage I, deel 2, geldt voor een inrichting vanaf 5 ton waterstof dat het een lagedrempelinrichting behelst. In dat geval zal de

inrichting een preventief veiligheidsbeleid dienen op te stellen. Voor een hogedrempelinrichting is de eis dat er een veiligheidsrapportage wordt opgesteld.

2.3

Veiligheidssituatie en beleid gemeente Neder-Betuwe

Uit de Beleidsvisie externe veiligheid Gemeente Neder-Betuwe (vastgesteld in 2015) Uit het externe veiligheidsbeleid van Neder-Betuwe volgt de volgende conclusie: Er zijn geen knelpunten met betrekking tot het plaatsgebonden risico vanwege Bevi-bedrijven. Mogelijk is wel sprake van potentiele knelpunten, omdat niet alle relevante risicocontouren als veiligheidszones in vigerende bestemmingsplannen zijn vastgelegd. Binnen de gemeente Neder-Betuwe is er één situatie waar in de huidige situatie bij een Beviinrichting de oriëntatiewaarde wordt overschreden. In de relevante vergunning zullen zodanige maatregelen worden vastgelegd dat de oriëntatiewaarde niet meer overschreden zal worden.

3 Ingevoerde gegevens 3.1 Risicobronnen Voor de risicoberekening is gebruik gemaakt van de memo Risico- en effectafstanden waterstoftankstations (2016)1 en de Handleiding Risicoberekeningen Bevi 4.1 (2019)2. De gebruikte scenario’s wijken enigszins af van het model van de RIVM memo, omdat in de situatie bij Dekker namelijk gebruik gemaakt van een waterstofrijke vloeistof, dat dient ter opslag van de waterstof / energie. Over deze vloeistof is nog weinig bekend, behalve dat het de gevaar aanduidingen H302 (harmful if swallowed) en H312 (harmful if in contact with skin) heeft. Verder is het een licht ontvlambare vloeistof, die minder licht ontvlambaar is als benzeen (LF1 stofcategorie). Om het worst-case scenario te beschouwen zijn we uitgegaan van ‘pentaan’ (LF2 stofcategorie) bij de insluitsystemen waar alleen ‘waterstofarme LOHC’ aanwezig is. In de andere gevallen (bij waterstof en ‘waterstofrijke LOHC’) is waterstof aangehouden. In werkelijkheid zal het risico kleiner zijn bij de opslag en transport van de ‘waterstofrijke LOHC’, omdat waterstof reactiever is dan de LOHC vloeistof. De volgende insluitsystemen worden gebruikt zoals genoemd in tabel 1. Naast deze systemen zullen er nog andere onderdelen zijn, zoals bijv.

reduceerventielen, midden- en lagedrukleidingen e.d., maar naar verwachting leveren deze geen wezenlijke bijdrage aan de risico’s (dit kan in een officiële vergunningsaanvraag nog worden nagegaan). Tabel 1 Insluitsystemen waterstof Lengte (meter)

Binnen de hoogste maximale afstand (3 kW/m3 wat overeenkomt met 1% letaliteit) telt de aanwezige populatie mee voor het groepsrisico.

4.3 Groepsrisico Het groepsrisico is verwaarloosbaar en dermate klein dat het niet zichtbaar is in de FN-grafiek. Voor 3 personen ligt het groepsrisico op een niveau van 9,5.10-13. Dit is ver beneden de oriëntatiewaarde (ter illustratie: de oriëntatiewaarde is voor 10 personen gelijk aan 1.10-5).

6 Conclusie Uit bovenstaande indicatieve beoordeling blijkt dat waterstofproductie dan wel de op- en overslag van waterstof in een vloeibaar medium als brandstof van de binnenvaartschepen door de Dekker Groep een geringe risicocontour (10-6/jaar) oplevert. Deze contour treedt net buiten de eigen inrichtingsgrens, maar raakt geen bebouwing omdat de contour op openbaar water is gelegen. Het groepsrisico blijft ruim onder de oriëntatiewaarde. Het voldoet hiermee aan het gemeentelijk beleid waarbij geen overschrijding van het plaatsgebonden risico en de oriëntatiewaarde plaatsvindt. Vanuit de regelgeving voor externe veiligheid zijn er vooralsnog geen juridische belemmeringen. In een vervolgstadium (bij uitwerking van de plannen) zal getoetst moeten worden aan de drempelwaarde voor Brzo-inrichting en de BBT-conclusies en PGS-35-richtlijn.
