Researchers in Hong Kong have designed an agrivoltaic system that uses blockchain tech and smart contracts to reduce uncertainties between PV system operators and grape farmers. The proposed system uses rainwater to clean solar panels and provide irrigation.

Australia needs to inspire a $421 billion (USD 282 billion) investment, accelerate coal closures and significantly speed up our renewable rollout to realise 1.5°C Paris agreement climate targets, according to modelling from an investor group.

Finance consultancy explains in a new report that the levelised cost of green hydrogen (LCOH) is well below USD 2/kg with subsidies. Using either PEM and alkaline electrolysers, green hydrogen normally has a lower levelised cost than pink hydrogen. Meanwhile, Australian authorities are trying to increase the competitiveness of the local hydrogen sector, and car companies are updating their fuel cell plans.

Over the Easter weekend there were a number of different tasks to work through – including sorting out what to do about electricity supply at home. Understandably I drew the short straw on that task.

Stanford University researchers have created a model to assess how much compressed air storage capacity might be needed for the deep decarbonisation of power systems, while compensating for the variability of wind and solar-based power systems. They applied the model to California’s energy system and found that compressed air could be very competitive on a dollars-per-kilowatt-hour basis.

Virtual Power Plants, or VPPs, are relatively mature in Australia due to the country’s high penetration of, and familiarity with, distributed energy resources. But claims of VPP success and participation may be overblown, with a considerable gaps between the numbers some platforms are claiming and the realms of possibility.

A consortium led by the Fraunhofer Institute for Solar Energy Systems (ISE) will test grid-forming inverters at a large-scale PV facility in southern Germany. The aim of the first tests is to examine the performance of the devices under real operating conditions, stress factors, and typical stress profiles.

Australian battery technology innovator Sparc Technologies is reporting “exceptional” results in its campaign to develop sustainably sourced hard carbon material for the production of anodes for the nascent sodium-ion battery market.

Rather than using solar or wind to power electrolysis, researchers are testing the competitiveness of photoelectrochemical cells to produce emissions-free hydrogen fuels.

Swiss researchers have looked at whether storage could be cheaper than curtailment in medium-voltage distribution networks with significant amounts of PV capacity. They considered storage costs, operational costs, grid constraints, electricity costs, PV generation models, and loads.
