A new converter topology for hybrid wind-solar

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

The third-quarter results for the inverter maker are in and look promising. All performance indicators are up for the steadily growing company.

New tool to assess costs and benefits of switching to green hydrogen

A result of a collaboration between global accounting and financial services firm KPMG, Canadian gas giant ATCO, Australia’s national science agency CSIRO and Australian Renewable Energy Agency (ARENA), H2City can be used to assess the costs and benefits of regional town or municipality switching to hydrogen.

Australia could fall apart under climate change. But there’s a way to avoid it

Four years ago in December 2015, every member of the United Nations met in Paris and agreed to hold global temperature increases to 2°C, and as close as possible to 1.5°C. The bad news is that four years on the best that we can hope for is holding global increases to around 1.75°C. We can only do that if the world moves decisively towards zero net emissions by the middle of the century.

LCOE on some Australian PV projects as low as $27-36/MWh as renewables close in on global grid parity

The latest figures released by BloombergNEF show new solar and onshore wind power plants have reached parity with average wholesale prices in California, China and parts of Europe. The technologies are winning the race to be the cheapest sources of new generation for two-thirds of the world’s population.

Tesla unveils a bigger, better, simpler Solar Roof – at a 40% discount

Elon Musk has officially launched the third phase of his crusade to make a successful solar roof tile, with promises that this time it is going to be a success.

PV against cancer

Research from the United States has demonstrated how PV technology can be used to kill cancer cells. Although still at an embryonic stage, the findings of the study and initial test results suggest solar power could be an effective tool in relation to light-activated fluorescent dyes for disease diagnosis, image-guided surgery and site-specific tumor treatment.
