Australia Activates First Renewable Power Station on
Decommissioned Coal Plant Site

Phil Mercer
June 16, 2023

SYDNEY —

The first large-scale battery to be built at an Australian coal
site has been switched on in Victoria's Latrobe Valley, east of
Melbourne.

The 150-megawatt battery is at the site of the former Hazelwood
power station in the southern Australian state of Victoria. The
station was built in the 1960s and closed in 2017.

The new battery was officially opened Wednesday and has the
ability to power about 75,000 homes for an hour during the
evening peak. The decommissioned coal plant produced 10 times
more electricity, but the battery's operators aim to increase its
generating capacity over time.

The Latrobe Valley has been the center of Victoria's coal-fired
power industry for decades, but the region is changing.

The new battery will store power generated by offshore wind farms
and is run by the French energy giant Engie, and its partners Eku
Energy and Fluence.

Engie chief executive Rik De Buyserie told reporters it is an
important part of Australia's green energy future.

"The commissioning of this battery represents a key milestone in
this journey and marks an important step in the transition of the
La Trobe Valley from a thermal energy power to a clean energy
power provider," he said.

The state of Victoria aims to have at least 2.6 gigawatts of
battery storage connected to the electricity grid by 2030 and 6.3
gigawatts by 2035.

Lily D'Ambrosio, Victoria's minister for climate action, energy
and resources, told reporters that the state government is
committed to boosting its renewable energy sector.

"It is important that we just do not sit around waiting for old
technology to disappear, close down, but we actually get in front
of it and make sure that we have more than sufficient supply to
meet our needs," she said. "That is what keeps downward pressure
on prices."

Australia has legislated a target to cut carbon emissions by 43%
from 2005 levels by 2030 and to achieve net zero emissions by
2050.

Electricity generation in Australia is still dominated by coal
and gas but there is a distinct shift to renewable sources of
power.

In April the Clean Energy Council, an industry association, said
that clean energy accounted for 35.9% of Australia's total
electricity generation in 2022, up from 32.5% in 2021.

Figuring out how to make the healthiest potato chips on the
planet

by SINTEF (Norway)
June 19, 2023

Researchers have now found out how to stop the formation of
harmful acrylamides when deep-frying potatoes to make potato
chips.

Frying potatoes causes the formation of harmful chemicals called
acrylamides. The acrylamide content in potato potato chips is
influenced by factors such as the potatoes themselves, storage
conditions and the heat treatment process. Researchers have been
looking into acrylamides together with the food packing company
Produsentpakkeriet in Frosta, north-east of Trondheim, Norway.

"Here we face an additional challenge because colder growth
conditions often mean that less mature potatoes are used to make
potato chips," says researcher Solveig Uglem at SINTEF, who has
been heading the research team. "Less mature potatoes contain
more sugar, and this can lead to a higher acrylamide content in
the potato chips that we make from them," she says.

Reducing food waste and boosting quality

According to the research team, this project has provided us with
new knowledge about the best ways of storing potatoes in order to
reduce food waste. It has shown us how to achieve optimum crisp
quality and minimize the risk of acrylamide formation.

The results demonstrate that three key factors are involved:

● Use of the right kind of potato

● Achieving the correct maturity before harvesting

● Achieving a correct and tailored storage temperature

As part of a three-year study, the researchers have also been
looking into the use of simple methods of measuring the sugar
content of potatoes. Such measurements, taken both before and
after harvesting and while the potatoes are in storage, are
important for ensuring that sugar levels are sufficiently low to
enable the potatoes to be made into potato chips.

The team discovered that measurements of sucrose and aspartic
acid contents in potatoes offered the best indicators of the
acrylamide levels that potato chips will obtain after deep
frying.

"However, this method is slow and requires the use of expensive
instruments," says Erlend Indergård, who has been participating
in the project. "We've found that measuring glucose
concentrations using a blood sugar meter that anyone can purchase
at a local pharmacy offers a quicker and more accessible means of
getting an indication of whether a potato's sugar content is too
high," he says.

So far, the method has been well received by potato growers. By
measuring the glucose content, they can get an indication as to
whether or not their potatoes are right for harvesting. It is
both unsustainable, and can result in major financial loss, if a
batch of potatoes has to be rejected because sugar levels are too
high. Potato growers should thus be encouraged to keep track of
the glucose content in their crop both immediately after
harvesting and during storage. This will enable them to take
action if they observe any changes in quality.
