Centralised offshore hydrogen production: Techno-economic optimisation and assessment of the benefit of aggregated power supply

Green hydrogen is expected to play a crucial role in the energy transition as it can be utilised for both storage purposes and as fuel for hard-to-abate sectors. One of the possible configurations for producing green hydrogen is by means of a central offshore hydrogen production platform powered by offshore wind energy. Producing hydrogen...

The impact of power management strategies and module sizing for offshore wind turbine integrated electrolysis

Solar and wind will displace fossil fuels as the main source of energy in a net-zero world. However, renewable energy sources provide intermittent power, hence an energy carrier that enables the balancing of demand and supply is needed. Here green hydrogen comes in place. <br/>In addition, the demand for green hydrogen is expected to rise in the...

The Optimal European Hydrogen Refueling Station Network for Heavy Duty Trucks

This study researched the optimal network of hydrogen refueling stations. The network is designed on a European scale and with a focus on heavy duty trucks. The design is created by means of a two-step optimization. The first step clusters truck representing datapoints into a predetermined number of stations by means of k-means clustering. The...

Challenges of integrating hydrogen in an operational port environment: Safety, Terminal Planning and Decision making aspects

Hydrogen is expected to be a significant force in this transition. Hydrogen can be produced using technologies that do not emit CO2 or other greenhouse gasses (“green H2”). Hydrogen can be transported in big quantities and long distances unlike electricity and can play the role of a clean fuel. The emerging hydrogen economy, which will be...

Quantifying risks to security of supply for 100% hydrogen in built-environment using Structured Expert Judgement

In this thesis, we explore a proposal from Stedin that advocates heating the city of Stad aan `t Haringvliet with hydrogen rather than natural gas. Switching from natural gas to hydrogen presents plenty of unknown factors which must be properly evaluated for an accurate and realistic risk picture, including the danger of running out of hydrogen....

Policy analysis for the supply chain business case of hydrogen refueling stations

On the 12th of December, 2015, the United Nations with 196 parties came to an agreement to limit global warming by reducing the greenhouse gas (GHG) emissions globally called ’the Paris Agreement’. In line with this agreement the European Union created the Green deal stating that by 2030 at least 55% of the greenhouse gas emissions need to be...

Techno-economic analysis of offshore platforms for green hydrogen production: Dive into system design and costs

The idea behind Power-to-Gas (P2G) is to help provide flexibility to renewable energy sources such as wind farms with intermittent nature. Additionally, hydrogen shows a great potential to help decarbonize several industries and its demand is expected to rise massively. Several studies for the technical and economic feasibility of P2G show...

Hydrogen Import Supply Chains: A study on the influence of various supply chain configurations on the cost price of hydrogen for different hydrogen carriers, considering the entire supply chain from export terminal to end-user

Hydrogen produced by electrolysis of water, powered by renewable energy, is seen as the key to enabling the energy transition and creating a new green economy. The result will be a trade market for low-carbon hydrogen where the trade routes will be determined by natural, technical, cost and geopolitical factors. However, to transport or store...

Hydrogen gas production from offshore wind: A cost-benefit analysis of optionality through grid connection

The decarbonisation of the Dutch power system cannot be accomplished by electrification alone. Although offshore wind power is to play a leading part in the future Dutch power system, long-term energy storage and hard-to-electrify energy consumers are in need of other energy carriers as well. Hydrogen gas is able to provide this system essential...

Exploring P2H futures in the North Sea using spatially explicit, techno-economic modelling

Hydrogen, as a fuel, will soon play a key role in helping economies transition to more sustainable practices. Having always garnered attention due to its non-polluting nature, the costs associated with its production have stood in the way of it being more widely used in society. Since the cost of clean energy to produce hydrogen is one of the...

Decarbonising the Residential Space Heating Sector of the Netherlands in 2050 through Three Decarbonisation Pathways: Hydrogen Boilers, Hybrid Heat Pumps and Electric Heat Pumps

Residential space heating demand in the Netherlands is met by natural gas boilers in 93% of Dutch households. In order to combat global climate change and limit the increase in global average temperatures to below 1.5°C by the year 2050, the Netherlands will have to cut down its emissions across all sectors of human activity to nearly zero. The...

Simulating smart charging optimization for electric vehicles: A quantification and statistical analysis of the cost reduction and emission reduction potential of an aggregated Dutch EV fleet
