Techno-economic analysis of underground hydrogen storage in Europe.

Hydrogen storage is crucial to developing secure renewable energy systems to meet the European Union's 2050 carbon neutrality objectives. However, a knowledge gap exists concerning the site-specific performance and economic viability of utilizing underground gas storage (UGS) sites for hydrogen storage in Europe. We compile information on European UGS sites to assess potential hydrogen storage capacity and evaluate the associated current and future costs.

Effect of Using Different Chemical Dispersing Agents in Grain Size Analyses of Fluvial Sediments via Laser Diffraction Spectrometry.

Laser diffraction spectrometry allows for efficiently obtaining high-resolution grain size data. However, pretreatment and dispersion of aggregates in sediment samples are essential pre-requisites for acquiring accurate results using this method. This study evaluates the effectiveness of five dispersing agents in deflocculating the investigated fluvial sediments and the resulting grain size distribution obtained by laser diffraction spectrometry.

Skin diseases in hospitalized geriatrics: a 9-year analysis from a University Dermatology Center in Germany.

The demographic trend of an ageing society is mirrored in the rising number of hospitalized geriatric patients in Germany. However, there is still a wide gap of knowledge regarding the dermatological diseases, comorbidities and performed procedures within this growingly important group of patients. The study was conducted as a retrospective monocentric data analysis of all patients 65 years or older from the Department of Dermatology, Medical Center-University of Freiburg, Germany.

Resources spent on dermatological emergency patients: A twelve-month prospective data collection from Germany.

Background And Objectives: Rising numbers of patients consulting emergency units are associated with an increased demand for material and personnel. In order to better quantify these resources, we performed an analysis of diagnostic procedures, treatment types, and the quantity and educational level of staff involved in emergency consultations.

Patients And Methods: The study was conducted as a prospective single-center survey over twelve months in the dermatology unit of a Germany university hospital.

420,000 year assessment of fault leakage rates shows geological carbon storage is secure.

Carbon capture and storage (CCS) technology is routinely cited as a cost effective tool for climate change mitigation. CCS can directly reduce industrial CO emissions and is essential for the retention of CO extracted from the atmosphere. To be effective as a climate change mitigation tool, CO must be securely retained for 10,000 years (10 ka) with a leakage rate of below 0.

Dermatological conditions presenting to the emergency dermatological unit of a university hospital in Germany.

Background And Objectives: Recently, there have been increasing numbers of patients consulting emergency units in all medical disciplines. Our aim was to analyze the demographics, referral mode, symptoms, localization of lesions, prior treatment, diagnoses and hospitalization rate of dermatological patients.

Patient And Methods: The study was conducted as a prospective single center survey over six months in the dermatology unit of a university hospital in Germany.
