Utilisation of waste heat from PEM electrolysers – Unlocking local optimisation

International Journal of Hydrogen Energy, Год журнала: 2023, Номер 48(72), С. 27872 - 27891

Recovery of heat from electrolysers is potentially interesting to increase the total system efficiency, reduce CO2 emissions, and economic feasibility both hydrogen production. This study examines different designs for utilisation (waste) a 2.5 MWel polymer electrolyte membrane (PEM) electrolyser. Redundancy important in design, ensure safe operation regardless demand consumer. We analysed cases with local consumption (with/without pump) coupling district heating network (DHN). Overall, 14–15% electricity input stack can be utilised by consumer, increasing efficiency 90% (HHV) CO2-savings 0.08 (DHN)-0.28 (direct use) tonne CO2/MWhheat, used. performed first-order techno-economic analysis showing that levelized costs electrolyser (8.4–36.9 €/MWh) fall within range other industrial sources below lower-temperature sources.

Levelized cost of hydrogen production in Northern Africa and Europe in 2050: A Monte Carlo simulation for Germany, Norway, Spain, Algeria, Morocco, and Egypt

International Journal of Hydrogen Energy, Год журнала: 2024, Номер 69, С. 184 - 194

The production of green hydrogen through electrolysis, utilizing renewable energies, is recognized as a pivotal element in the pursuit decarbonization. In order to attain cost competitiveness for hydrogen, reasonable generation costs are imperative. To identify cost-effective import partners Germany, given its limited capabilities, this study undertakes an exhaustive techno-economic analysis determine potential Levelized Cost Hydrogen Norway, Spain, Algeria, Morocco, and Egypt year 2050, which represents critical milestone European decarbonization efforts. Employing stochastic approach with Monte Carlo simulations, paper marks significant contribution projecting future ranges, acknowledging multitude uncertainties inherent related parameters emphasizing importance randomness these assessments. Country-specific Weighted Average Capital calculated create refined understanding political economic influences on formation, rather than using uniform value across all investigated nations. Key findings reveal that among evaluated nations, PV-based emerges most cost-efficient alternative countries except Spain presenting lowest at 1.66 €/kg 3.12 €/kg, followed by Algeria (1.72 3.23 €/kg) Morocco (1.73 3.28 €/kg). Consequently, economically favorable options, Germany advised prioritize imports from countries. Additionally, derived onshore wind Norway (2.24 3.73 offers feasible alternative. ensure supply chain diversity reduce dependency single source, mixed strategy advisable. Despite having electricity cost, shows highest Hydrogen, primarily due Capital.

White knight or partner of choice? The Ukraine war and the role of the Middle East in the energy security of Europe

Energy Strategy Reviews, Год журнала: 2023, Номер 49, С. 101116 - 101116

Опубликована: Июль 13, 2023

The Ukraine war has forced Europe to redefine its energy security policies towards more diversification and less reliance on Russian energy. As an energy-rich relatively close region, the Middle East can play a potentially important role in Europe's future security. However, short-term static view East's readiness as partner conceals dynamic nature of external policy this region. Closer cooperation with requires holistic approach informed strategies that consider realities perspectives energy-exporting countries. This paper provides analysis by considering political economic factors such capacity, domestic reforms, long-term supply reliability. Using perspective based international economy, for between are highlighted. Integration North Africa's markets infrastructure deliver supplies foster transition East. Oil diplomacy Gulf countries is necessary price stability compensation oil Europe. Finally, there opportunities European strengthen trade partnerships (particularly Qatar) thus become involved interstate competition abundant gas rapprochement solicits re-examination EU order achieve mutually beneficial cooperation.

Опубликована: Дек. 7, 2021

Renewable energy has a crucial role in facing climate change. One promising strategy is the creation of communities that require active involvement from bottom-up perspective. Their implementation difficult, as they currently rely on local policies, community readiness, and technological availability. The objective this paper to provide qualitative overview concepts strategies at European level. aim identify common approaches are framing development communities, understand most successful steps leading their growth. To achieve objective, threefold methodology provided: (1) an updated review policies dealing with Italian level; (2) European-funded projects under Horizon 2020 work program; (3) some existing Europe. results outline series considerations lessons learned useful for implementing transition pathway real case, which also presented paper. conclusions will future directions research, particularly relation coming actions case.

Urban climate resilience through hybrid infrastructure

Current Opinion in Environmental Sustainability, Год журнала: 2022, Номер 55, С. 101158 - 101158

Urban infrastructure will require transformative changes to adapt changing disturbance patterns. We ask what new opportunities hybrid infrastructure—built environments coupled with landscape-scale biophysical structures and processes—offer for building different layers of resilience critical dealing increased variation in the frequency, magnitude phases climate-related disturbances. With its more diverse components internal logics, opens up alternative additive ways through infrastructure, by providing a wider range functions responses. Second, points toward greater ongoing (re)design at landscape level, where structure function can be constantly renegotiated recombined.

Challenges in increasing Women's participation in the energy transition in ASEAN and G7 countries: A qualitative approach based on the three tenets of justice

Energy Policy, Год журнала: 2024, Номер 191, С. 114163 - 114163

Опубликована: Май 18, 2024

Ensuring an inclusive and just transition towards a low-carbon economy has become increasingly important. This paper emphasises the challenges in increasing extent of women's participation energy ASEAN G7 countries. In this paper, two research questions are addressed: First, what barriers women face countries participating transition? Second, policies that can be implemented to ensure is both inclusive? Using VOSviewer, we found gap literature, particularly terms perspectives context To bridge gap, collected data by conducting interviews with working sector Moreover, employed scientific literature strengthen analysis. These were qualitatively analysed applying Jenkins' three tenets justice transition.
