It’s one of the biggest international events of the year for solar thermal experts and for the first time it was held in Australia!
The SolarPACES (Solar Power and Chemical Energy Systems) executive committee meeting and conference enticed experts from countries including USA, Spain, Germany, France and China. During the event they discussed important solar thermal issues and all the latest developments in the technology, markets and the future of the technology.
CSIRO’s Wes Stein told us, ‘We’re hearing from the experts about their experiences in their different countries, not only around research and technology programs, but also around the measures that have made advancements possible in their country.’
This is important stuff for the future of solar thermal research and technology – to help get this technology operating efficiently and make it more affordable.
CSIRO’s two solar towers were operating for the visitors during the event as working examples of the technology.
We’ve been working with two scientists at the top of the photovoltaics (PV) field – Professor Anders Hagfeldt and Professor Sten-Eric Lindquist.
Both scientists are from Sweden and have travelled to the CSIRO Energy Centre in Newcastle to check out our facilities and work with our photovoltaics team…whilst also enjoying summer in the southern hemisphere.
Not only does he play some mean drums in a band called ‘Fat Cotton‘ but Professor Hegfeldt really knows his dye-sensitised solar cells. He’s one of the top 50 scientists in his field! (Watch our short video on the production of dye-sensitised solar cells).
Professor Sten-Eric Lindquist, from Uppsala University, is working with us in our labs, giving us the benefit of his considerable experience in photovoltaics. Professor Lindquist has been examining the properties of semi-conducting photovoltaic materials.
In a neat twist Professor Lindquist was Professor Hagfeldt’s university supervisor (*cough* some 20 years ago).
Greeting the sun and a lovely rosy dawn, our heliostats in formation for Earth Hour (8.30pm, Saturday 23 March).
Want some practical energy saving tips? Our energy efficiency expert, Glenn Platt, blogged with The Newcastle Herald recently and answered all your ‘hot’ questions including saving money on your power bills and electric cars for the future.
And the final post in our series of hot new projects! ‘Plug and Play solar’ is not a new PlayStation game (we wish); it is a project to develop energy management software to manage the various renewable and traditional energy sources a building or site might have.
For example, remote mining operations or towns – like Marble Bar or Hermannsburg – have traditionally been powered by fossil fuels like gas and diesel, but more and more are turning to renewable sources such as solar. Traditionally, it has been up to the system operator to decide when to use which sources. This is often not as easy as it sounds, mostly because of the variable nature of renewable energy sources. Often this means that fossil fuel backup systems are left running just in case a cloud might pass or wind might drop – not the most fuel-efficient solution. What would really help would be an automated system able to intelligently handle multiple fossil and renewable sources.
CSIRO is working on the answer.
Plug and Play is a system where a user can ‘plug’ in the various sources and the system automatically and intelligently ‘plays’, or works out what source to use, when to use and how it should be used. You tell the system what your top priorities are – minimising diesel usage, lowering maintenance costs, or maximising power availability, for example – and it will make the best decisions about when to schedule the diesel generator, when to make the most of the solar panels and when to charge the batteries.
The tool will also be invaluable when designing new remote area power supplies. It’ll help to choose the best mixture of energy technologies for the site’s needs and decide how to size them. And then, instead of needing to have custom hardware and software designed to manage that unique mix, the Plug and Play system will help do it for you.
Senior project scientist Dr John Ward says it’s in the commissioning phase of these power systems that some of the most significant benefits will be seen. “Reducing the need for ‘on the ground’ engineers will be an important outcome,” he told the solar blog. “Currently each is different and unique and needs considerable specialised and costly engineering.”
This project is also expected to have flow-on effects that’ll benefit more than just remote towns. “Next stop would be rural areas, specifically with SWER (single-wire earth return) power lines,” Dr Ward says. “Such areas only have a very ‘weak’ connection to the grid, so they face similar issues to the islanded systems being targeted for this project.
“Our team believes that as the electricity grid evolves to have more interplay between consumer demand and resource availability, there’ll be a role for Plug and Play type systems to become mainstream in every part of the electricity grid.”
It’s no easy feat however. The project is worth over $2.9 million and will take several years to complete. We’re working with ABB Australia, the United States’ National Renewable Energy Laboratory (NREL).
The first phase of the project will involve the development of the technology and the second phase will see pilot systems set up in both the United States and Australia. The final product will be a cost effective, retrofit system that can be easily installed, without the need for expert labour. We think it will ultimately be of benefit to thousands of remotely based residents.
The project is one of four projects announced in December 2013 as part of the Australian Renewable Energy Agency and United States-Australia Solar Energy (USAEC) Collaboration. It builds on our existing expertise in areas including solar intermittency, customer load management, the virtual power station, mini grid planning, and the work we’ve done on Australian standards for inverter energy systems and load control.

Our scientists are pretty passionate about their work. So much so that they don’t just take their work home with them – they take it on holiday.
Scientist Scott Watkins recently took this holiday snap of an organic printed solar cell floating in Callala Bay on the NSW south coast. He thought the cell deserved a treat after helping secure funding for a new, $87 million Australia-US partnership in solar cell research. The funding will be used to establish the US-Australia Institute for Advanced Photovoltaics (IAP). This centre will work on solar cells – those that convert sunlight directly into electricity.
The solar cell partnership is a parallel program to the solar thermal research partnership that we reported on back in December.
For CSIRO, our involvement in the IAP represents a great chance to continue our work on manufacturing thin-film solar cells while working alongside new colleagues with deep expertise in existing, silicon-based solar cells. Who knows where this research will take us next.
Today we celebrate the career of Dr Lan Lam – the primary inventor of CSIRO’s UltraBattery – an invention putting two technologies together into one awesome storage unit! Bringing down the cost of hybrid electric vehicles and making it easier to integrate more renewable energy into the grid are just some of the achievements of the UltraBattery.
“It was always my dream to create a better battery. I knew the success of hybrid electric and electric vehicles were dependent on it,” said Dr Lam.
This year the first UltraBattery will be released in the automotive market, powering hybrid electric vehicles (HEV) in Japan, United States, South America, Europe and Asia. The use of HEVs decreases our reliance on fossil fuels and thereby…
