Why the mega plan to send Australian solar to Asia (almost) flopped
12:20 | The idea was simple: why not use solar energy from Australia’s sunny and spacious north to power Singapore, which has no space for renewables of its own?

12:33 | China is often held up as leading the way in renewable energy, but it’s actually the USA that has most enthusiastically embraced battery energy storage to help stabilize the electricity grid.
12:53 | Electrifying everything with renewable technologies like solar PV, wind turbines and battery energy storage is a ‘holy grail’ that energy transition naysayers tell us is an impossible dream.
9:49 | Fossil fuels still supply 80% of our energy. And people point to this number to say it’s impossible to switch to renewables. But their argument overlooks just how much energy we waste – and how we could do it better.
17:30 | 100% electrification from renewables, backed up with interconnections and energy storage is now just around the corner. But there are still bumps in the road. Can we overcome them in time?
13:05 | What if you could build your electricity grid out at sea and just bring cables to shore where they’re needed?
11:58 | The cost savings, energy efficiency improvements, and speed of installation that new materials are facilitating may just make the difference in the race for decarbonisation.
11:33 | Heating our homes with cold water! Sounds absurd? It’s not. Heat pumps are revolutionizing the way we heat and cool our homes and cities. We went to the German city of Mannheim to find out how.
42:25 | To stop climate change, the energy system must be transformed worldwide. Very little time remains to accomplish this. But there are places where this renewable future has already arrived.
13:06 | We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann.
12:44 | How about a well insulated shipping container that can handle 1300 degrees Celsius and be delivered to small operators who need low grade heat, or to district heating systems to keep you toasty warm in the winter?
10:23 | Donnel Baird’s ambitious plan to rip the fossil fuel infrastructure out of aging buildings and upgrade it with smarter, cleaner, healthier technology.
12:06 | Welcome to South Australia, a place where the winds of change are quite literal and the sun doesn’t just warm our homes but also powers them.
11:12 | A US company called FORM Energy is on the cusp of installing its first 10MW / 1 gigawatt hour iron-air energy storage facility.
12:43 | Pumped Storage Hydro could literally be the lynch pin to get us to 100% renewable global electricity grids without having to pillage the earth (and deep seabed) of critical minerals.
13:05 | Will batteries for hundreds of millions of future electric vehicles rob the planet of all its precious minerals? And what about all the minerals and materials for billions of wind turbines and solar panels?
9:06 | Around 4% of global electricity is used for providing tap water. That number is only going to increase and its carbon emissions rival that of aviation. But a surprisingly simple idea can make our water supply more sustainable: In-pipe energy.
11:57 | Building solar farms and wind parks is one thing. Plugging them into the grid is another. How does our power system need to change to cope with more renewables?
13:55 | The energy transition solutions of the 21st Century will take many forms, with a complex mix of different power producers. Moving energy across ever greater distances will overcome much of the intermittency of renewables like wind and solar.
15:22 | Ramez Naam outlines the changes we need to make to get out of our own way and create a stronger, more reliable renewable energy grid.
7:45 | Why aren’t more people investing in Africa’s green energy?
8:00 | In Indonesia, where the majority of nickel for lithium-ion batteries is produced, the production process emits large amounts of carbon and pollution. It doesn’t have to be this way. Indonesia sits along the Ring of Fire, one of the most geologically active regions in the world.
10:28 | Liquid metal battery technology has the potential to revolutionise utility scale energy storage, but it’s been a long and difficult road for the creator, Donald Sadoway, and his company, Ambri Inc.
13:31 | Gas suppliers and boiler makers are lobbying hard for the use of hydrogen in domestic heating systems. But is that the right road to take?
11:10 | Gravity energy storage has real potential to provide cheap reliable grid balancing electricity to compliment the ever growing volume of intermittent renewables on our power grids, but only if it’s done in the right way.
11:42 | A video about capturing and utilising the enormous quantities of heat currently going to waste from more than seven million data centres and tens of millions of industrial facilities around the world.
14:20 | A team at MIT has combined and improved several existing technologies into a flexible modular solution that could be as much as 30x cheaper than existing lithium-ion technology.
16:19 | 15 million jobs are set to be lost from the fossil fuel industry in the coming years, but more than three times that will be created in the renewable sector.
50:07 | In the season opener, David Letterman travels to India. Back in the U.S., Cecily Strong travels to Florida and Nevada.
13:24 | Balancing renewable power sources on modern electricity grids is becoming one of the greatest logistical challenges of our time.
7:25 | Sitting in a row outside of the factory, these giant batteries are the size of freight containers. Powered by vats of iron and saltwater, they’re called iron flow batteries.
12:19 | Manganese dioxide flow batteries may offer a very cost effective way of bridging the gap between short duration lithium-ion batteries and longer duration technologies like hydrogen.
9:50 | Fossil fuel replacement isn’t enough, Solomon Goldstein-Rose explains in this compelling talk: we need to rapidly develop a new global system capable of producing 12 times the amount of clean electricity we generate today.
12:47 | The launch of the world’s first fully electric wirelessly chargeable car.
28:25 | Green hydrogen produces zero emissions and many believe it holds the key to limiting global warming. So is it the big hope for the future or a multi-billion euro mistake?
14:50 | One UK company have just announced a £16 billion project that will be generating 3.6GW of solar, wind and battery capacity in South Morocco.
11:16 | Now, one company plans to replace the burners in disused coal fired power plants with an energy storage system that can not only provide useful grid balancing power, but also bring gainful employment back to hard working people.
6:50 | Making clean energy isn’t enough: We also have to move it.
7:54 | The business model featuring a one way street of electricity supply will soon be consigned to the history books, replaced by a smart distributed grid with multi-directional imports and exports, often driven by local community schemes. Here’s a great example.
15:42 | Blue hydrogen is being promoted by natural gas producers as the simplest and cheapest answer to decarbonising our economies. But recent studies have shown that it’s overall greenhouse gas emissions footprint is worse than natural gas.
18:55 | The climate emergency requires climate solutions. And fast! A new analysis suggests that 90% of the job could be achieved by just a handful of disruptive technologies that are very real indeed.
11:19 | Energy consumption for heating and cooling is expected to triple in the next thirty years, as populations grow, and more people move into cities. A lot of that energy demand is used in compressing and pumping fluids.
13:58 | A new smart domestic hot water storage tank has been developed that not only heats water 20% more efficiently, but can also use electrical energy when it’s free or even negatively priced.
46:11 | All over the world, storage technologists and battery pioneers are looking for ways to store renewable energy. From developing fast batteries to storing heat in basalt and salt.
14:12 | A UK company has developed a heat pump system based on the principles of the Stirling Engine, using no HFC refrigeration gases and with a 30% saving in energy costs compared to existing systems.
11:18 | The energy storage sector is becoming a pretty crowded field as more and more companies come up with solutions that will be crucial to dealing with the intermittency of renewable technologies.
9:52 | About windmills, coal, natural gas, and the disconnected power grid in Texas.
