The latest round-up of energy-efficiency projects and innovations from Australia and around the world.

Solar battery storage systems for Adelaide government buildings

A local company will install lithium-ion batteries at three Adelaide sites: the State Library of South Australia, the Art Gallery of South Australia and Adelaide High School. ‘Battery storage has transformed the renewable energy sector and opened up a whole new range of possibilities,’ said Adelaide Lord Mayor, Martine Hesse.

Australian Energy Efficiency Policy Handbook launched

The Energy Efficiency Council has released the Australian Energy Efficiency Policy Handbook, a comprehensive guide to the policies that underpin energy-efficiency improvements in Australia. It provides state and federal governments with a detailed plan and evidence-based recommendations for improvement in energy efficiency across all sectors of the Australian economy.

E3 program contributes to over a billion in savings

Over the past year, the Equipment Energy Efficiency (E3) Program has contributed to savings of more than $1 billion in abated energy costs in the Australian and New Zealand economies. A report on the program’s achievements for 2015-16 highlights the activities that have contributed to these benefits.

Wind powers South Australia’s mid-winter electricity

Wind turbines provided 83% of South Australia’s power needs in the 24 hours to 4 pm on July 11. ‘The state now has 683 turbines, which have generated more than $6 billion of investment and hundreds of jobs in regional communities – as well as lots of renewable energy,’ said Clean Energy Council policy manager, Alicia Webb.

Liquid nitrogen truck engine refrigeration trial

A UK supermarket chain is trialling a delivery truck cooled by a liquid nitrogen powered engine, which should eliminate all emissions associated with its refrigeration. The vehicle is expected to abate up to 1.6 tonnes of carbon dioxide in its first three months of using the technology.

Hi-tech living, breathing wall is more than meets the eye

A ‘breathing’ wall at Lendlease’s Barangaroo South headquarters is set to cut the building’s HVAC needs by a third, as well as significantly reducing reflected noise levels. It also absorbs and processes a substantial 24 litres of CO2 per hour, one of the highest CO2 removal levels ever recorded.

Australia’s first ‘energy autonomous’ medical centre

The Cork Trust Memorial Medical Centre in Dorrigo, NSW, is powered by its own 36kW grid-connected solar and battery storage system. It’s expected that the system, when completed, will generate up to 20% more power than the building’s average annual requirement.

Solar and wind combine for greater reliability

Australia’s first large-scale solar farm to be co-located with wind turbines will be built near Canberra. A 10 MW solar PV plant will be built adjacent to the existing Gullen Range Wind Farm. ‘Co-location provides more continuous energy generation, as wind farms tend to generate more energy overnight whilst solar only generates during the day. Gullen Wind Farm generates more power in winter and the new solar farm will generate more in summer,’ said ARENA CEO, Ivor Frischknecht.

The impact of renewable energy on system security

The Australian Energy Market Commission is investigating the ability of wholesale energy market frameworks to complement increasing levels of renewable energy as the industry transforms. Challenges in maintaining power system security are emerging because of the physics of maintaining technical generation parameters like voltage and grid frequency.

Additional benefits of energy-efficient buildings

Improving the energy efficiency of buildings brings additional advantages to a community, such as environmental benefits, and improvements in public health and employment. New research by the World Resources Institute examines the central role building efficiency can play in shaping sustainable cities.

Geothermal: HVAC at our feet

Using the earth itself for our heating and cooling is an idea that has not yet reached its full potential. The main drawbacks are high installation costs and low awareness from those who could benefit. An estimated 90% of buildings can be heated by ground-source heat pumps, according to Bill Nowak of NY-GEO.

Smart tech takes over

Smart, clean technologies have taken the market by storm, promising to change the built environment and grid infrastructure forever. According to a report by US-based Marcom Capital Group, smart grid and battery/storage investments both doubled in the second quarter of 2016. The uptake of efficient lighting is also accelerating.
