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?
11:27 | How do we get ourselves off our dependence on fossil fuels? And if the alternative is intermittent renewables then how are we going to keep our homes constantly warm during the colder months? Perhaps our friends in Scandinavia can provide some answers…
9:53 | The lithium-ion battery has powered us for decades. But for a renewable future, we need a new solution—and fast. So what are our options?
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.
11:17 | Graphene is about to become a reality in electric vehicle batteries, increasing energy density by 40% or more, and reducing charge times to just a few minutes.
11:59 | The market for energy storage is still dominated by lithium-ion technology. But cheaper, greener and safer alternatives are being developed all the time.
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.
11:41 | Sodium-ion batteries have been overshadowed by lithium-ion for decades, but there’s a thousand times more sodium in the earth’s crust than there is lithium.
13:24 | Balancing renewable power sources on modern electricity grids is becoming one of the greatest logistical challenges of our time.
12:07 | Some say it’s the fuel of the future that will soon power large parts of our economies. Others say it’s just a hoax propagated by the oil and gas industry.
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.
11:36 | Ammonia has great potential as a fuel source, if only a way could be found to produce it without the huge carbon dioxide emissions it currently creates.
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.
11:35 | Lithium Sulphur (or Sulfur) batteries have been on the ‘hopeful technology’ list for over a decade now. Now, after ten years of waiting, suddenly two different solutions have been announced within a week of each other.
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.

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.
9:16 | Billions of unassuming rocks on the seafloor could help humanity save itself from the ravages of climate change.
