An hourly energy balance analysis is presented of the Australian National Electricity Market in a 100% renewable energy scenario, in which wind and photovoltaics (PV) provides about 90% of the annual electricity demand and existing hydroelectricity and biomass provides the balance. Heroic assumptions about future technology development are avoided by only including technology that is being depl...

There is wide public debate about which electricity generating technologies will best be suited to reduce greenhouse gas emissions (GHG). Sometimes this debate ignores real-world practicalities and leads to over-optimistic conclusions. Here we define and apply a set of fit-for-service criteria to identify technologies capable of supplying baseload electricity and reducing GHGs by amounts and wi...

The developing region of SAARC (South Asian Association for Regional Cooperation) is home to a large number of people living below the poverty line. In future, providing affordable, universally accessible, reliable, low to zero carbon electricity in this region will be the main aim. A cost optimal 100% renewable energy system is simulated for SAARC for the year 2030 on an hourly resolved basis....

Presented is a methodology to analyze the expected Levelised Cost Of Electricity (LCOE) in the face of technology uncertainty for AcceleratorDriven Subcritical Reactors (ADSRs). It shows that flexibility in the design and deployment strategy of an ADSR park demonstrator significantly reduces its expected LCOE. The methodology recognizes in the conceptual design a range of possible technological...

These products and services need to target a reduction in the levelised cost of energy (LCoE), optimise energy yield or reduce the need for unnecessary access to larger turbines in deeper water, further from shore. In addition, there are major opportunities for the UK to build on its existing strengths and experience to deliver exportable products and services into the global offshore wind O&M ...

To quantify the potential value of technological advances to the photovoltaics (PV) sector, this paper examines the impact of changes to key PV module and system parameters on the levelized cost of energy (LCOE). The parameters selected include module manufacturing cost, efficiency, degradation rate, and service lifetime. NREL’s System Advisor Model (SAM) is used to calculate the lifecycle cost...

This research introduces a ‘Hydrogen Interconnector System’ (HIS) as novel method for transporting electrical energy over long distances. The system takes electricity from stranded renewable assets, converts it to hydrogen in an electrolyser plant, transports the demand centre via pipeline, where is reconverted either gas turbine or fuel cell plant. paper evaluates competitiveness of technology...
