The blocks can be used to run steam turbines at power stations as a clean alternative to burning coal, and at a fraction of the price of storing energy in batteries.

Black turbine blades seem to reduce bird collisions, but it’s important to know why.
Building renewable energy infrastructure involves mining for materials such as lithium, graphite and cobalt. If not done responsibly, that could cause huge environmental damage.
Tesla founder Elon Musk has described hydrogen-powered cars as “mind-bogglingly stupid”. So is he right?
The Japanese government will retire its fleet of old, inefficient coal-fired generation by 2030. If Japan’s commitment to coal weakens, our exports can expect a big hit.
A clean energy transition is vital in Australia, but big projects like Forest Wind must take local communities with them.
Geothermal reservoirs supply more than 15% of New Zealand’s electricity. The heat energy stored in geothermal fields is vast but not infinite.
Yes, transitioning Australia to a zero-carbon economy is essential, but the federal government must remedy this imbalance.
We discovered wind farms in Spain that had carved up peat bogs, causing them to release carbon to the atmosphere.
We are now at the start of the sixth great wave in economic disruption, driven by renewables, electomobilty and smart-city technologies.
New Zealand’s electricity generation is already more than 80% renewable, but experts warn a 100% target would require significant over-building of renewable generation that would rarely be used.
Grid-scale batteries could be at least double the cost of those in electric vehicles.
A mix of wind, solar photovoltaics, and some natural gas would be more cost-effective than Inga 3 for South Africa and the DRC.
Households shouldn’t have to do all the heavy lifting in the renewables transition. A new solar farm shows organisations and businesses how it’s done.
Electricity is only one part of the green energy puzzle we need to solve.
More than 80% of the world’s offshore wind blows further from land than conventional wind farms can reach.
There are many possible outcomes from the closure of the smelter – just don’t expect lower electricity prices to be one of them.
Energy companies are marketing a new fuel: ‘renewable’ natural gas. But it’s not the same from a climate change perspective as wind or solar energy.
Land acquisition remains a major challenge for Indonesia’s increasing renewable energy installations.
Some coal workers have the right skills and work in the right location to get a job in renewables. But many, such as semi-skilled machine operators, cannot.
