Gasification of excavated landfill waste is one of the promising options to improve the added-value chain during remediation of problematic old landfill sites. Steam gasification is considered as a favorable route to convert landfill waste into H₂-rich syngas. Co-gasification of such a poor quality landfill waste with biochar or biomass would be beneficial to enhance the H₂ concentration in the syngas as well as to improve the gasification performance. In this work steam co-gasification of landfill waste with biochar or biomass was carried out in a lab-scale reactor. The effect of the fuel blending ratio was investigated by varying the auxiliary fuel content in the range of 15e35 wt%. Moreover co-gasification tests were carried out at temperatures between 800 and 1000°C. The results indicate that adding either biomass or biochar enhances the H₂ yield where the latter accounts for the syngas with the highest H₂ concentration. At 800°C the addition of 35 wt% biochar can enhance the H₂ concentration from 38 to 54 vol% and lowering the tar yield from 0.050 to 0.014 g/g-fuel-daf. No apparent synergetic effect was observed in the case of biomass co-gasification which might cause by the high Si content of landfill waste. In contrast the H₂ production increases non-linearly with the biochar share in the fuel which indicates that a significant synergetic effect occurs during co-gasification due to the reforming of tar over biochar. Increasing the temperature of biochar co-gasification from 800 to 1000°C elevates the H₂ concentration but decreases the H₂/CO ratio and increases the tar yield. Furthermore the addition of biochar also enhances the gasification efficiency as indicated by increased values of the energy yield ratio.

As of 2003 15 hydrogen refuelling stations (HRSs) have been deployed in the Netherlands. To become established the HRS has to go through a permitting procedure. An important document of the permitting dossier is the quantitative risk assessment (QRA) as it assesses the risks of the HRS associated to people and buildings in the vicinity of the HRS. In the Netherlands a generic prescribed approach exists on how to perform a QRA however specific guidelines for HRSs do not exist. An intercomparison among the QRAs of permitted HRSs has revealed significant inconsistencies on various aspects of the QRA: namely the inclusion of HRS sub-systems and components the HRS sub-system and component considerations as predefined components the application of failure scenarios the determination of failure frequencies the application of input parameters the consideration of preventive and mitigation measures as well as information provided regarding the HRS surroundings and the societal risk. It is therefore recommended to develop specific QRA guidelines for HRSs.

Maritime shipping is a key factor that enables the global economy however the pressure it exerts on the environment is increasing rapidly. In order to reduce the emissions of harmful greenhouse gasses the search is on for alternative fuels for the maritime shipping industry. In this work the usefulness of hydrogen and hydrogen carriers is being investigated as a fuel for sea going ships. Due to the low volumetric energy density of hydrogen under standard conditions the need for efficient storage of this fuel is high. Key processes in the use of hydrogen are discussed starting with the production of hydrogen from fossil and renewable sources. The focus of this review is different storage methods and in this work we discuss the storage of hydrogen at high pressure in liquefied form at cryogenic temperatures and bound to liquid or solid-state carriers. In this work a theoretical introduction to different hydrogen storage methods precedes an analysis of the energy-efficiency and practical storage density of the carriers. In the final section the major challenges and hurdles for the development of hydrogen storage for the maritime industry are discussed. The most likely challenges will be the development of a new bunkering infrastructure and suitable monitoring of the safety to ensure safe operation of these hydrogen carriers on board the ship.

This brochure offers an overview of the main applications of fuel cell and hydrogen technologies and how they work and provides insights into our programme and our accomplishments.

Only emissions-free vehicles which include battery electric (BEVs) and hydrogen fuel cell trucks (FCEVs) can provide for a credible long-term pathway towards the full decarbonisation of the road freight sector. This document lays out the methodology and assumptions which were used to calculate the total cost of ownership (TCO) of the two vehicle technologies for regional delivery and long-haul truck applications. It also discusses other criteria such as refuelling and recharging times as well as potential payload losses.

The document provides information on safety planning monitoring and reporting for the concerned hydrogen and fuel cell projects and programmes in Europe. It does not replace or contradict existing regulations which prevails under all circumstances. Neither is it meant to conflict with relevant international or national standards or to replace existing company safety policies codes and procedures. Instead this guidance document aims to assist in identifying minimum safety requirements hazards and associated risks and in generating a quality safety plan that will serve as an assisting guide for the inherently safer conduct of all work related to the development and operation of hydrogen and fuel cell systems and infrastructure. A safety plan should be revisited periodically as part of an overall effort to pay continuous and priority attention to the associated safety aspects and to account for all modifications of the considered system and its operations. Potential hazards failure mechanisms and related incidents associated with any work process or system should always be identified analysed reported (recorded in relevant knowledge databases e.g. HIAD 2.0 or HELLEN handbooks papers etc.) and eliminated or mitigated as part of sound safety planning and comprehensive hydrogen safety engineering which extends beyond the recommendations of this document. All relevant objects or aspects that may be adversely affected by a failure should be considered including low frequency high consequences events. So the general protection objective is to exclude or at least minimise potential hazards and associated risks to prevent impacts on the following:

• People. Hazards that pose a risk of injury or loss of life to people must be identified and eliminated or mitigated. A complete safety assessment considers not only those personnel who are directly involved in the work but also others who are at risk due to these hazards.
• Property. Damage to or loss of equipment or facilities must be prevented or minimised. Damage to equipment can be both the cause of incidents and the result of incidents. An equipment failure can result in collateral damage to nearby equipment and property which can then trigger additional equipment failures or even lead to additional hazards and risks e.g. through the domino effect. Effective safety planning monitoring and reporting considers and minimises serious risk of equipment and property damage.
• Environment. Damage to the environment must be prevented. Any aspect of a natural or the built environment which can be harmed due to a hydrogen system or infrastructure failure should be identified and analysed. A qualification of the failure modes resulting in environmental damage must be considered.

The simultaneous photocatalytic H2 evolution with environmental remediation over semiconducting metal oxides is a fascinating process for sustainable fuel production. However most of the previously reported photocatalytic reforming showed nonstoichiometric amounts of the evolved H2 when organic substrates were used. To explain the reasons for this phenomenon a careful analysis of the products and intermediates in gas and aqueous phases upon the photocatalytic hydrogen evolution from oxalic acid using Pt/TiO2 was performed. A quadrupole mass spectrometer (QMS) was used for the continuous flow monitoring of the evolved gases while high performance ion chromatography (HPIC) isotopic labeling and electron paramagnetic resonance (EPR) were employed to understand the reactions in the solution. The entire consumption of oxalic acid led to a ~30% lower H2 amount than theoretically expected. Due to the contribution of the photoKolbe reaction mechanism a tiny amount of formic acid was produced then disappeared shortly after the complete consumption of oxalic acid. Nevertheless a much lower concentration of formic acid was generated compared to the nonstoichiometric difference between the formed H2 and the consumed oxalic acid. Isotopic labeling measurements showed that the evolved H2 HD and/or D2 matched those of the solvent; however using D2O decreased the reaction rate. Interestingly the presence of KI as an additional hole scavenger with oxalic acid had a considerable impact on the reaction mechanism and thus the hydrogen yield as indicated by the QMS and the EPR measurements. The added KI promoted H2 evolution to reach the theoretically predictable amount and inhibited the formation of intermediates without affecting the oxalic acid degradation rate. The proposed mechanism by which KI boosts the photocatalytic performance is of great importance in enhancing the overall energy efficiency for hydrogen production via photocatalytic organic reforming.
