Dr David Finn - Australian Tritium EV chargers exporting to the world

Dr David Finn is co-founder, Managing Director and CEO at Tritium, developer of the award-winning Australian-designed electric vehicle fast charger which made its European debut at the prestigious Intersolar 2014. Tritium has signed commercial deals for the technology, spanning across three European countries, and also industry compliance in Canada and the USA. 

The Veefil charging system – developed over 10 years and backed by a $1.15 million Early Stage Commercialisation grant – boasts the ability to charge an EV 20 times faster than plugging it into the wall at home, and to add 50km range to an EV battery in just 10 minutes.

Tim Forcey- NSW gas demand could halve in 10 years

Tim Forcey is the Energy Advisor at the Melbourne Energy Institute (MEI) at The University of Melbourne, and is a regular guest on Beyond Zero (speaking previously on pumped hydro energy storage). In this podcast, Tim Forcey speaks about a new MEI paper which found that gas demand in NSW could fall to as much as half within ten years. 

MEI made a submission to the New South Wales Parliament's Upper House Inquiry into 'The supply and cost of gas and liquid fuels in NSW'. Tim was recently invited to testify at this Inquiry and present his work. The NSW goverment, AGL, Santos and many other organisation also testified, focusing on the supply side and warning of gas shortages. However Tim's research was really the only one that was focusing on the demand side. 

Network costs often make up the largest part of a consumer’s gas or electricity supply bill. Investments in network infrastructure are based on estimates of future demand. If demand is overestimated, unnecessary infrastructure is built. Such poor investment decisions drive up the costs that small and large gas consumers must pay.

Recent unprecedented electricity price increases across eastern Australia were partly due to overinvestment in network infrastructure that, in turn, was partly a result of year-after-year overestimation of electricity demand by the responsible planning bodies.

A present danger is that future gas demand in eastern Australia now likewise being overestimated.

Carol Ride - Psychology for a Safe Climate

Carol Ride is a psychologist and couple psychotherapist, who is well known in the climate movement in Melbourne for the last several years. Carol Ride is President of Psychology for a Safe Climate (PSC) a group of  psychologists and helping professionals working together to contribute psychological understanding within the community to support and facilitate strong and urgent action on climate change. We know the climate science and the solutions, now Carol joins Beyond Zero to urge everyone to take action - and not to leave it to someone else.

Psychology for a Safe Climate's booklet Let's Speak about Climate Change provides an opportunity for readers to reflect on how they and those around them have responded to news of climate change. The booklet provides insight into how we can better encourage conversations and community engagement.

PSC provides psychological education and support to climate activist groups, including the upcoming Conference - Climate Change: turn-on or turn off? featuring Dr Susan Murphy is a writer, radio producer, film director and Zen Roshi.

George Marshall - Why Our Brains Are Wired To Ignore Climate Change

George Marshall is a communicator, campaigner and author of Don’t Even Think About It: Why Our Brains Are Wired To Ignore Climate Change (2014) about the psychology of climate change, and described by the climate scientist Dr. James Hansen, as “illuminating and important”. George Marshall co-founded Climate Outreach and Information Network (COIN) in 2004 and is currently Director of Projects.

Beyond Zero's Niels and Michael caught up with George while he was in Australia for a series of events for the Sustainable Living Festival hosted by Psychology for a Safe Climate.

Why, despite overwhelming scientific evidence, do we still ignore climate change? And what does it need for us to become fully convinced of what we already know? “We need to start recognising that we need each other, that we all face a common threat to the things we all hold dear, and that debate is welcome and necessary”

Dr Scott Watkins - Pollinate Energy

Dr Scott Watkins is a Technology developer, science communicator and formerly Research Leader for Thin Film Photovoltaics in CSIRO’s Future Manufacturing Flagship. He has appeared previously on the Beyond Zero show talking about his CSIRO research into developing organic Photovoltaic cells. This time Scott joins to talk about his new venture, that is with Pollinate Energy, a social enterprise whose mission is to:
Improve the lives of India’s urban poor by giving them access to sustainable products that make their lives better.

Dr Ashraf Uddin UNSW

Dr Ashraf Uddin is an Associate Professor in the world renowned School of Photovoltaic and Renewable Energy Engineering at UNSW. The Beyond Zero team is also joined by expert guest interviewer Dr Scott Watkins who also specialises in organic PV.

Dr Cameron Stanley RMIT

Dr Cameron Stanley is a Research Fellow in the School of Aerospace, Mechanical and Manufacturing Engineering at RMIT University.

Photovoltaic (PV) cells typically convert between 15-20% of the incident sunlight into electrical energy and dissipate the remaining energy as heat. Hybrid photovoltaic/thermal (PVT) collectors use a fluid flowing adjacent to the PV cells to collect some of this dissipated heat and transfer it as useful energy e.g. for domestic hot water. As well as collecting heat energy, which would be otherwise wasted, the fluid serves to cool the PV cells and enhance their electrical performance.

RMIT is currently developing a hybrid PVT receiver suitable for linear concentrators, which aims to produce a thermal output of 150ºC and an electrical yield of around 9%. To achieve these temperatures a technique known as spectral beam splitting is used. The high grade thermal output from these receivers is intended to be used for industrial heat processes as well as absorption chillers.

Philip Sutton: Making a Safe Climate Restoration Actually Happen

Philip Sutton

Philip Sutton is the Manager and Chief Strategist of RSTI (Research and Strategy for Transition Initiation), a non-profit organisation that engages in strategy development and engagement to catalyse the urgent initiation of a full scale transition to a sustainable economy – focusing especially on the very rapid emergence of the necessary social and political commitment to make this transition possible.

Philip speaks to Beyond Zero's Niels and Michael about a new research and engagement project series which aims at making a safe climate restoration actually happen.

Listen here to the podcast

The Safe Climate Science project sets out to apply best practice safety standards, and broad-based ethics, to generate and win support for a new paradigm for climate goals. Under 3 years in development, these projects build on the climate work that Philip has been doing since 2006 and the project is now ready for your involvement kicking off in early 2015.
Philip is co-founder of Safe Climate Australia and past-President of the Sustainable Living Foundation and the Australia New Zealand Society for Ecological Economics. Philip co-authored Climate Code Red, which puts forward a case for emergency action on climate change.

Time to write down the value of NSW networks

Carbon + Energy Markets (CME) Director Bruce Mountain, and Consultant Paul Szuster, join Beyond Zero radio's Niels and Michael to talk about the NSW Government's plan to partially privatise, two of its three distribution network service providers. One of the key issues is that the assets are over-valued.
Considering the conflicting interests and the high price NSW household consumers are currently paying for network services, the Public Interest Advocacy Centre (PIAC) commissioned CME to examine the regulatory valuation at privatisation, and identify relevant issues.

Alan Pears AM

Alan Pears AM is Sustainable Energy & Climate Researcher at RMIT University and one of Australia's leading energy efficiency experts. He has worked in the sustainable energy and environment fields since the late 1970s, and been an expert adviser to federal, state and local governments across Australia, as well as community groups and the private sector. Alan Pears AM is a Member of the Order of Australia for contribution to climate and environmental policy, 2009.

Beyond Zero's Niels and Michael speak to Alan about how successful energy efficiency policies have been harmed by recent government decisions. Alan describes the 'crazy' descision by the current federal government to close the Energy Efficiency Opportunities scheme implementation with all funding cut from July 2014. As of 2011, it was saving $800 million a year at an average carbon cost of around minus $95/tonne of CO2e avoided and a benefit-cost ratio of 3.67. Similar energy efficiency programs have been cut by the Queensland state government, as well as other policies being senstitive to the government of the day.
