Direct Coupling Feasibility Evaluation: Predicting the Price of Hydrogen Produced by Solar Energy

This report aims to evaluate the feasibility of a small pilot plant placed near Broome, Australia to produce 3 tons of hydrogen per day using photovoltaic (PV) energy. Using PVsyst, a PV modelling software, the maximum power operating points were determined for a test layout. This was then transformed to other layouts which allowed the optimum...

Feasibility Study on the Operation of an Iron Heat Treatment Furnace with Hydrogen Fuel

The work presented in this report investigates the effect of replacing natural gas fuel in a radiant tube burner in an industrial furnace with hydrogen fuel. The flue gas is fully contained inside the radiant tube burner and does not come into contact with the iron products inside the furnace. The burner interacts with the process side of the...

The gas quality in a hydrogen distribution grid: Computation of the influences of distribution through the existing grid on the hydrogen quality

Although the Dutch energy supply is gradually progressing from fossil fuels to renewable energy sources, the consequences for the grid are becoming increasingly evident. Meanwhile, the gas extraction from the Groningen natural gas reserve is de- clining as the induced earthquakes in the northern Netherlands persist. Hydrogen, as a flexible...

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...

Optimisation of a Hybrid Wind, Solar, Electrolysis plant serving the Dutch Electricity and Hydrogen Market

This research evaluates and optimises the competitiveness of a combined wind, solar, and electrolyser plant in the Dutch electricity and hydrogen market. For the electricity market, this study used the EPEX spot market, where most electricity is traded. The hydrogen market is far less transparent than the electricity market; hence, a market had...

Conditions for Profitability & Grid Effects of PV-Electrolysis

In this graduation research conditions affecting the profitability as well as the grid effects of a PV-Electrolysis system have been studied using the site of PV park Oosterwolde as a case study. During the study a wide variety scenarios have been created from a set of influential parameters on the PV-Electrolysis business case, which have...

Evaluation of hydrogen sensors and location inside a metering cabinet

The Hydrogen Heating Studies project in the Green Village at the TU Delft researches the safe application of hydrogen to heat buildings. This study aims to evaluate hydrogen sensor technologies for residential safety, including the determination of the sensor location inside a standard (Dutch) metering cabinet that achieves the fastest response...

Development of a roadmap to a net-zero fleet: A technical and financial evaluation

The maritime sector plays an important role in energy transition because offshore vessels are used for building offshore renewables but also have high emissions. The European Union (EU) has determined that from 2025 the maritime sector must pay per ton of CO2 emission. Heerema Marine Contractors (HMC) is an essential player in the maritime...

Sodium Borohydride As a Circular Hydrogen Carrier: An Energy Efficient Link Between Hydrogen Release and Sodium Borohydride Synthesis

This thesis presents a novel method for using sodium borohydride (NaBH₄) as a circular hydrogen carrier, addressing the current lack of commercially viable approaches for hydrogen storage in NaBH₄. The traditional approach of using NaBH₄ for circular hydrogen storage through hydrolysis was reevaluated, leading to the development of a novel...

Optimization study of a hybrid powertrain: Optimization of the system components and energy management of a zero-emission hydrogen powered boat

The company H2 Marine Solutions has designed a zero-emission hydrogen powered boat. This boat is compared to its fossil fuel counterpart more than twice as heavy. The reason for this is that the system components that are used in the hybrid powertrain of the hydrogen powered boat are heavier. The main question of this research is: How can we...
