Zapata Arango, Mateo (author), Hoppe, T. (author), Itten, A.V. (author), Blok, K. (author)Background<br/>At the COP21, cities were recognised as key actors in combatting climate change. In supporting cities, climate city networks such as transnational climate networks (TCNs) and national climate networks (NCNs) have emerged to enable cities in building capacities and formulating climate policy whilst also encouraging citizen...journal article 2024

Langer, J.K.A. (author), Blok, K. (author)Ocean Thermal Energy Conversion (OTEC) is an emerging renewable energy technology using the ocean’s heat to produce electricity. Given its early development stage, OTEC’s economics are still uncertain and there is no global assessment of its economic potential, yet. Here, we present the model pyOTEC that designs OTEC plants for best economic...journal article 2023

Ruiz Manuel, I. (author), Blok, K. (author)Corporate climate initiatives such as the Science-Based Targets initiative and RE100 have gained significant prominence in recent years, with considerable increases in membership and several ex-ante studies stating how they could bring substantive emissions reductions beyond national goals. However, studies evaluating their progress are scarce,...journal article 2023

(author)Geospatial analysis is useful for mapping the potential of renewables like solar PV. However, recent studies do not address PV’s bankable potential for which project financing can be secured. This paper proposes a framework that incorporates project finance into geospatial analyses to obtain the bankable potential of renewables. We demonstrate...journal article 2023

Popa, O.E. (author), Blok, Vincent (author), Katsoukis, Georgios (author), Schubert, Cornelius (author)We propose and illustrate a model for evaluating the moral impact of technologies from a pluralist perspective. We conceptualize technological artefacts as having moral profiles that consist of the values served and disserved along five levels of decision-making: (1) problem, (2) strategy, (3) resources, (4) product and (5) design. The notion of...journal article 2023

van Oorschot, Janneke (author), Sprecher, Benjamin (author), Rijken, Bart (author), Witteveen, Pieter (author), Blok, Merlijn (author), Schouten, Nico (author), van der Voet, Ester (author)Buildings are an important part of society's environmental impacts, both in the construction and in the use phase. As the energy performance of buildings improve, construction materials become more important as a cause of environmental impact. Less attention has been given to those materials. We explore, as an alternative for conventional...journal article 2023

Blok, K. (author), Ramirez, Andrea (author), Tanzer, Samantha Eleanor (author)Negative emission technologies such as biomass with carbon capture and storage (bioCCS) may become an important instrument to limit global warming. Currently, estimates of CO2 avoidance cost for bioCCS vary widely. Using a case study of a cement plant, this paper illustrates how this variance is partially attributable to the system boundary...journal article 2023

(author)The first two objectives were to establish which stimulation parameters of kilohertz frequency alternating current (KHFAC) neuromodulation influence the effectiveness of pudendal nerve block and its safety. The third aim was to determine whether KHFAC neuromodulation of the pudendal nerve can relax the pelvic musculature, including the anal...journal article 2022

Langer, J.K.A. (author), Zaaijer, M B (author), Quist, J.N. (author), Blok, K. (author)Onshore wind potentials are commonly mapped with site selection criteria that either fully include or exclude land for wind farms. However, current research rarely addresses the variability of these criteria, possibly resulting in overly conservative or optimistic potentials. This paper proposes a method to account for the variability of site...journal article 2022

Langer, J.K.A. (author), Quist, J.N. (author), Blok, K. (author)Ocean Thermal Energy Conversion (OTEC) is a promising renewable energy technology that is the most economical at large scale. But contemporary literature does not address how OTEC could reach such scale with current technology, and what the techno-economic impact of location-dependent factors and technological learning are. This paper tackles...journal article 2022

(author), Rahayu, Harkunti Pertiwi (author), Blok, K. (author)The current focus of offshore wind industry and academia lies on regions with strong winds, neglecting areas with mild resources. Photovoltaics' cost reductions have shown that even mild resources can be harnessed economically, especially where electricity prices are high. Here, we study the technical and economic potential of offshore wind...journal article 2022
