Many sub-Saharan countries currently lack reliable electricity infrastructure, particularly in rural areas. Solar mini-grids can help remedy this situation. However, they require effective storage solutions, for which green hydrogen (GH₂) offers a possibility. Establishing green hydrogen as a storage …

"In the first quarter of 2025, 42.5% of net electricity generated in the EU came from renewable energy sources. In June 2025, solar was the largest source of EU electricity for the first time, with multiple countries producing record amounts of solar power. At least 13 member states set new monthly solar …

The generation of electrical power from renewable sources such as wind and solar power is on the rise. However, the nature of this power generation is characterized by a relatively high level of unpredictability, whereas the demand for electrical power continues to grow steadily. These factors – among …

This paper evaluates the potential impacts of introducing low-carbon intensity hydrogen technologies in two oil refineries with different complexity levels, emphasizing the role of hydrogen production in reducing CO2 emissions. The novelty of this work lies in three key aspects: Comprehensive system …

In het Kenniscafé praat men elke maand met Groningse wetenschappers en onderzoekers over actuele thema's. Marten van der Laan, vertelt over zijn betrokkenheid bij het project Groningen Stroomt Door dat is opgericht om overbelasting van het elektriciteitsnet tegen te gaan. Moeten we wel ruimte maken …

This report aims to provide clarity on the legal framework surrounding the regulation of flexibility in the Dutch electricity grid that solves or reduces the congestion issues in the Netherlands. Congestion in the Dutch electricity grids1 has rapidly increased over the past two years. Local grid operators …

The energy community movement has grown considerably over the past ten years. Energy communities are also expanding their activities. However, room for new energy projects is limited because of grid congestion. Therefore, citizen energy communities (CECs) are looking for ways to reduce the pressure on …

Dynamic energy contracts, offering hourly varying day-ahead prices for electricity, create opportunities for a residential Battery Energy Storage System (BESS) to not just optimize the self-consumption of solar energy but also capitalize on price differences. This work examines the financial potential …

The intermittency of renewable energy technologies requires adequate storage technologies. Hydrogen systems consisting of electrolysers, storage tanks, and fuel cells can be implemented as well as batteries. The requirements of the hydrogen purification unit is missing from literature. We measured the …
