Energy and Water system integration in the urban environment

The transition from a fossil to a renewable energy system presents challenges in ensuring reliable and affordable energy supply. This dissertation addresses these challenges by proposing an integrated system approach to designing a renewable energy and water system on the neighborhood level. The concept, known as Power-to-H3, involves converting...

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 ...

The Impact of System Integration on System Costs of a Neighborhood Energy and Water System

The fossil-based energy system is transitioning towards a renewable energy system. One important aspect is the spatial and temporal mismatch between intermitted supply and continuous demand. To ensure a reliable and affordable energy system, we propose an integrated system approach that integrates electricity production, mobility, heating of...

Introducing Power-to-H3: Combining renewable electricity with heat, water and hydrogen production and storage in a neighbourhood

In the transition from fossil to renewable energy, the energy system should become clean, while remaining reliable and affordable. Because of the intermittent nature of both renewable energy production and energy demand, an integrated system approach is required that includes energy conversion and storage. We propose a concept for a...
