In the realm of photoconversion of CO2 into high-value chemicals, the importance of near-infrared (NIR) light is gradually gaining recognition. Relative to ultraviolet (UV) and visible light, NIR light (700-2500 nm), accounting for ca. 50% of solar energy, ...

Here, we describe the testing of geophysical techniques to monitor and evaluate a pilot site for in-situ CO2 mineral storage in Helguvik, Iceland. In addition to hydraulic spinner tests and borehole logging data, the stratigraphic sequence of the reservoir ...

Atmospheric deposition delivers carbon to glacier surfaces, including from fossil fuel and biomass combustion. Nonetheless, spatial variation in the sources of organic and black carbon deposited on glaciers is poorly understood, along with their role in dr ...

In recent years, an increasing number of studies have reported on forest declines and shifts in species composition in response to changing climatic conditions (Rigling et al. 2012). The intensification of droughts through rising evaporative demand (i.e., ...

Seasonal storage of thermal energy has the potential to both significantly reduce the total energy requirements for heating and cooling of buildings, and also allow for the flexibility to store thermal energy from intermittent sources. With approximately h ...

The global energy sector stands at a critical juncture, with the imperative shift towards renewable energy sources posing challenges and opportunities for existing infrastructure and societal norms. This thesis explores the multifaceted dynamics of transit ...

Arctic fjords are experiencing rapid environmental shifts due to climate change, which may have significant impacts on marine biodiversity and ecosystem functioning. However, the impact of climate change on fjord biodiversity is difficult to quantify given ...

Shallow ground-source heat pumps (GSHPs) are a promising technology for contributing to the decarbonisation of the energy sector. In heating-dominated climates, the combined use of GSHPs for both heating and cooling increases their technical potential, def ...

Herein, we describe the status of bio-derived plastics as well as the existing and emerging technologies that are available for their post-consumer end-of-life valorization. We first present how bio-derived plastics can be produced from renewable materials ...

Electricity production and consumption must be balanced for the electrical grid. However, the rapidly growing intermittent power sources are now challenging the supply-demand balance, leading to large flexibility needs for grid management. The plant integr ...
