Two boundary value control algorithms: For the heat equation on the finite domain using the unified transform method

In this work we investigate two boundary-value control algorithms for the heat equation on the finite interval. The algorithms we discuss here are based on the unified transform method (UTM), a method invented by A. S. Fokas to solve boundary value problems of partial differential equations. We first inspect the boundary-value control algorithm...

Utilisation of waste heat from PEM electrolysers: Unlocking local optimisation

Recovery of heat from electrolysers is potentially interesting to increase the total system efficiency, reduce CO₂ emissions, and increase the economic feasibility of both hydrogen and heat production. This study examines different designs for the utilisation of (waste) heat from a 2.5 MW_el polymer electrolyte membrane ...

Waterstof voor gebouwverwarming: Naar 500.000 woningen op waterstof in 2030

For the transition of the built environment towards carbon neutrality, heating with green hydrogen can obtain a key role, especially in countries with a well developed natural gas infrastructure, like the Netherlands. Leading studies show that the existing transport and distribution gas network can be transformed for hydrogen transport at...

Fuel cell electric vehicle to grid & H2: Balancing national electricity, heating & transport systems a scenario analysis for Germany in the year 2050

In a 2050 fully renewable national electricity, heating and road transport system primary energy supply comes from non-dispatchable power generation such as solar and wind energy. Both negative and positive dispatchable balancing power plants need to balance the system. This work investigates whether parked and grid connected (Vehicle-to-Grid...
