Storing energy in large pumped hydro schemes sounds simple. But engineering and terrain challenges have put Snowy 2.0 well off track – while grid-scale batteries get better and better
The demand for the minerals needed to build clean energy technology currently exceeds the available supply. If this issue continues, governments may find it hard to reach their clean energy targets.
20 years ago, solar and wind were expensive enough to make nuclear seem like an option for Australia. With cheap renewables a reality, there’s simply no point to domestic nuclear.
China is a major investor in Latin America’s renewable energy and critical minerals like lithium, but countries like Chile are also taking steps to secure their own clean energy future.
In the late 1980s, well diggers in Mali struck a rich source of naturally-created hydrogen. Now prospectors are scouring South Australia, looking for natural hydrogen.
In the fact of economic uncertainty, one question remains: Is it worth investing in a more sustainable Canada, or will it become just another economic burden?
It’s 2023 and residents in remote First Nations communities still suffer from regular power disconnections. The fix is simple: put solar on every roof. But there are challenges to overcome first.
The enhanced partnership could accelerate Australia’s transition from fossil fuel exporter to clean energy powerhouse. But success is far from assured.
To address the climate crisis, governments need to limit new fossil fuel developments. But foreign investors are often protected under trade and investment agreements.
Hydrogen is getting a lot of attention as the EPA prepares to propose new emissions rules for power plants. But it has a problem: almost all of it used today is made from fossil fuels.
