As the European Union intensifies its response to climate emergency, increased focus has been placed on hard-to-abate energy-intensive industries. Primary among these is steel industry, a cornerstone of economy and industry. With emergence new hydrogen-based steelmaking options, particularly through hydrogen direct reduction, structure global production supply chains will transition from being based low-cost coal resources that electricity therefore production. This study examines techno-economic options for three countries Germany, Spain, Finland under five different chain configurations compared local Results suggest high costs transportation make cost competitive produced with imported hydrogen, ranging 465 545 €/t crude (CS) 380–494 €/tCS 2030 2040, respectively. Conversely, imports hot briquetted iron Morocco become economically chains. Given capital energy intensive nature critical investment decisions are required in this decade, research serves provide deeper understanding Europe.

Abstract Global progress in energy transitions to support climate mitigation goals has been slower than anticipated; this prompted shifts away from traditional paradigms of regulated ownership towards a model democratization by local communities and individuals. For example, the United States, over 250 cities, counties, states have made pledges reach 100% renewable electrification target dates ranging 2020 2050. However, availability infrastructure competition for resources, as well lack awareness these limitations, present significant barriers overcome. In study, we explored subset 31 cities assess their current electricity generation how much further they go meet goals. Through an energyshed framework, estimated powerplant allocation each city assuming power various non-renewable resource types, look at ‘best case scenario’ renewable-sourced handful order understand existing planned mixes 2021 following 20 years. It is likely most will 10% demand with energy, best cases scenarios reaching between 35% 65% penetration, within next 20–30 This highlights need infrastructural development sector, intentional planning efforts make reality.

Highly renewable energy systems for island regions provide opportunities to investigate fully self-sufficient energy-industry systems. New perspectives into the nature of 100% suggest that a Power-to-X Economy may emerge, as electricity will become fundamental carrier. In with high shares, availability low-cost storage options is essential balance shares variable electricity, especially solar PV and wind power. While direct electrification most cost-effective efficient solution, indirect through power-to-X processes required those demands cannot be directly electrified. Using LUT Energy System Transition Model, system transition pathways role technologies were investigated case Hawaiʻi comparing cost-optimal routes reaching net-zero emissions by 2040 2050 current government projections. Additionally, e-fuel import scenarios are compared self-supply scenarios. By installing 39 GW PV, responsible 96% total generation 32 TWh, levelised cost in can reduced 27.5 €/MWh. Total capacities, including stationary batteries, pumped hydro storage, vehicle-to-grid reach 46 GWhcap 2050, throughput at 7.7% demand. Due low projected costs these options, they only 38% LCOE 2050. These results highlight importance economies such achieve levels independence.
