Hydrogen has been ‘just around the corner’ for decades, but now offers serious alternatives decarbonising global heat, power and transport.
The need for energy storage to balance intermittent and inflexible electricity supply with demand is driving interest in conversion of renewable via electrolysis into a storable gas. But, high capital cost uncertainty regarding future performance improvements are barriers investment water electrolysis. Expert elicitations can support decision-making when data sparse their development uncertain. Therefore, this study presents expert views on cost, lifetime efficiency three technologies:...
Solar PV is rapidly growing globally, creating difficult questions around how to efficiently integrate it into national electricity grids. Its time-varying power output model credibly because depends on complex and variable weather systems, leading difficulty in understanding its potential limitations. We demonstrate the MERRA MERRA-2 global meteorological reanalyses as well Meteosat-based CM-SAF SARAH satellite dataset can be used produce hourly simulations across Europe. To validate these...
Reanalysis models are rapidly gaining popularity for simulating wind power output due to their convenience and global coverage. However, they should only be relied upon once thoroughly proven. This paper reports the first international validation of reanalysis energy, testing NASA's MERRA MERRA-2 in 23 European countries. Both reanalyses suffer significant spatial bias, overestimating by 50% northwest Europe underestimating 30% Mediterranean. We derive national correction factors, show that...
Ageing is a fact of life. Just as with conventional forms power generation, the energy produced by wind farm gradually decreases over its lifetime, perhaps due to falling availability, aerodynamic performance or conversion efficiency. Understanding these factors however complicated highly variable availability wind. This paper reveals rate ageing national fleet turbines using free public data for actual and theoretical ideal load from UK's 282 farms. Actual are recorded monthly period...
Automotive proton-exchange membrane fuel cells (PEMFCs) have finally reached a state of technological readiness where several major automotive companies are commercially leasing and selling cell electric vehicles, including Toyota, Honda, Hyundai. These now claim vehicle speed acceleration, refueling time, driving range, durability that rival conventional internal combustion engines in most cases outperform battery vehicles. The residual challenges areas improvement which remain for PEMFCs...
Energy policy often builds on insights gained from quantitative energy models and their underlying data. As climate change mitigation economic concerns drive a sustained transformation of the sector, transparent well-founded analyses are more important than ever. We assert that associated data must be openly available to facilitate higher quality science, greater productivity through less duplicated effort, effective science-policy boundary. There also valid reasons why code not open:...
Wind and solar power have experienced rapid cost declines are being deployed at scale. However, their output variability remains a key problem for managing electricity systems, the implications of multi-day to multi-year still poorly understood. As other energy-using sectors electrified, shape demand will also change. We develop an open framework quantifying impacts weather on supply using Renewables.ninja DESSTINEE models. demonstrate this case study Britain National Grid's Two Degrees...
Britain and Germany saw unprecedented growth of variable renewable energy (VRE) in the last decade. Many studies suggest this will significantly raise short-term power system operation costs for balancing congestion management. We review actual development these costs, their allocation policy implications both countries. Since 2010, have increased by 62% (with a five-fold increase VRE capacity) remained comparable capacity doubling). Within this, stayed level (–4%) decreased substantially...
This paper presents the optimal design and operation of integrated wind-hydrogen-electricity networks using general mixed integer linear programming energy network model, STeMES (Samsatli Samsatli, 2015). The comprises: wind turbines; electrolysers, fuel cells, compressors expanders; pressurised vessels underground storage for hydrogen storage; pipelines electricity overhead/underground transmission lines; fuelling stations distribution pipelines. spatial temporal variability demands...
