The flame-made nanostructured agglomerates achieved <italic>ca.</italic> 200% higher syngas production rates and the highest redox capacity so far reported for ceria.
Deployment of wind and solar electricity technologies is crucial for the energy transition, yet anticipated deployment rates differ widely often underestimating actual deployments. This issue significant countries like Aotearoa New Zealand, leading way in major transitions. study addresses two main issues: historical underestimation need to synthesise various future scenarios assess their potential impacts on system. To address these problems, an empirical modelling approach based logistic...
Photovoltaic (PV) technologies have evolved over time for higher efficiency, with the adoption of larger wafers, passivated emitter and rear cells (PERC), bifacial panels. The advancements in production PV components call updated life cycle assessments (LCAs) systems. We undertook a LCA utility-scale solar plant Aotearoa New Zealand using monocrystalline silicon PERC panels, establishing carbon, materials energy footprint associated stages farm its components. By comparing different...
ABSTRACT The technologies for offshore wind projects have evolved to larger turbines, which provide enhanced efficiency and power generation. Permanent magnet synchronous generators with a direct drive design enabled these advancements. In recognition of deeper insights into their implications, this paper addresses the need updated life cycle assessments (LCAs) systems adopting large turbines. An LCA an project in Aotearoa New Zealand employing 15‐MW total capacity 1 GW, was undertaken....
Reforming of methane is practiced on a vast scale globally for the production syngas as precursor many commodities, including hydrogen, ammonia and synthetic liquid fuels. Solar reforming can reduce greenhouse gas intensity by up to about 40% using solar thermal energy provide endothermic heat reaction, traditionally supplied combustion some feed. This has potential enable derived fuels drop in replacements conventional with significantly lower CO2 than liquids (GTL) processes. However,...
In recognition of deeper insights into the implications wind farm deployments, this paper addresses need for an updated Life Cycle Assessment (LCA) onshore generation systems, using 4.3 MW turbines and direct drive permanent magnet synchronous generators. The environmental energy performances were estimated through LCA plant under construction in Aotearoa New Zealand with a total nameplate capacity 176 MW. This study used real data showing literature overestimates civil works underestimates...
The reaction pathway of sulfur dioxide electro-oxidation on platinum and gold substrates is investigated here using a combination static rotating electrode voltammetric methods. A electrocatalyst does not need to be modified in order display high activity, meaning the substrate inherently more active than platinum. Analysis diffusion behavior these suggests that both kinetic limitations control oxidation each electrode. However, it proposed similar pathway, involving adsorption subsequent...
Annual performance simulations provide a valuable tool for analysing the viability and overall impact of different concentrating solar power (CSP) component system designs. However, existing tools work best with conventional systems are difficult or impossible to adapt when novel components, configurations operating strategies interest. SolarTherm is new open source simulation that fulfils this need community. It includes framework library flexible CSP components control can be adapted...
This study examined the feasibility of green hydrogen as a transport fuel for very heavy vehicle (VHV) fleet in New Zealand. Green is assumed to be produced through water electrolysis using purely renewable energy (RE) an electricity source. chose vehicles potential market hydrogen, because it considered “low-hanging fruit” sector where battery electrification less feasible. The large-scale, decentralized, embedded (dedicated) grid-connected system production polymer electrolytic membrane...
The efficient and effective use of land that agriPV, or agrivoltaic, systems offer is especially appealing for Aotearoa-New Zealand, since more than a third its area serves agricultural purposes. However, several factors might constrain the implementation agriPV systems, different values preferences need consideration from community acceptance perspective. As first step, high-level investigation into potential suitability in Aotearoa–New Zealand was undertaken. influence performance were...
A critical step of sulfur based thermochemical cycles for hydrogen production from water is the endothermic decomposition sulfuric acid. The necessary heat can be provided by concentrated solar radiation. receiver-reactor has been developed and built to investigate this process. Experiments with test reactor were carried out in DLR furnace Cologne confirmed technical feasibility a containing porous ceramics strategy operation iteratively optimized respect chemical conversion efficiency....
