6. Nanoplasmonic Alloy Hydrogen Sensors
Sammanfattning : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. LÄS MER
7. Electrification of the basic materials industry – Implications for the electricity system
Sammanfattning : The European energy-intensive basic materials industry must achieve deep reductions in CO2 emissions to meet the targets set out in the Paris Agreement. The rapid decline in the cost of renewable electricity makes expanded electrification an attractive option for eliminating the dependence of the industry on fossil fuels. LÄS MER
8. Electrocatalysts for sustainable hydrogen energy : disordered and heterogeneous nanomaterials
Sammanfattning : With the current global greenhouse gas emissions, our remaining carbon budget is depleted in only 7 years. After that, several biophysical systems are predicted to collapse such as the arctic ice, coral reefs and the permafrost, leading to potentially irreversible consequences. LÄS MER
9. Appraisal of strategies to improve thermophilic hydrogen production exploiting Caldicellulosiruptor species
Sammanfattning : The transition from a fossil to a bio-based economy is of vital importance to stem the effects of ongoing climate change.This bio-based economy will necessitate the production of both biofuels and chemical compounds from biologicalsources. LÄS MER
10. The role of methane and hydrogen in a fossil-free Swedish transport sector
Sammanfattning : Drastic reductions of greenhouse gas emissions are required to limit the severe risks associated with a changing climate. One measure is to disrupt the fossil-fuel dependency in the transport sector, but it appears difficult and costly in comparison to other measures. LÄS MER
