9:27 | Rooftop wind power has been a goal for micro power generators around the world for many years now. There’s a new kid on the block that has no visible moving parts, makes no noise, and generates 50% more power than standard solar PV panels.
12:48 | More and more mainstream organisations now say our politicians have already failed, and that average global temperature increases higher than 1.5 degrees Celsius above pre-industrial levels are now inevitable. So, who are we to believe?
11:27 | A new research paper has found some very strange temperature differences in the Eastern Pacific Ocean between climate models and observed ‘real world’ measurements. So, what’s going on?
12:42 | Solar cooling sounds like a contradiction in terms, but it could become a household phrase in a sustainable future.
13:04 | 35 years ago scientists discovered we were badly damaging the ozone layer, so a major global initiative was created to repair it. At the same time scientists also discovered that greenhouse gas emissions were causing dangerous levels of warming in our atmosphere…
12:48 | Concrete accounts for 8% of global CO2 emissions and it’s usage is set to skyrocket in the coming decades as the world’s population grows and moves towards more urban environments.
11:42 | Hydrogen is not easy to store. Now two separate and completely unconnected teams claim to have worked out how to store hydrogen in powder form. So is this a genuine breakthrough or yet more wishful thinking?
12:56 | The arctic region is a key driver of global climate patterns. This video assesses four peer reviewed research papers, published in the summer of 2022.
12:45 | Modern technology has enabled timber to be engineered in such a way that it can be used as an apparently “carbon negative” replacement for steel in very tall buildings. But can we afford the land required to create vast new timber plantations?
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?
12:03 | Once all the carbon costs of extracting, processing and manufacturing are taken into account, how much lower is the overall lifetime carbon footprint of an EV compared to and ICE car?
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…
10:40 | Algae is one of the most successful organisms on earth, and we humans are only just starting to understand its potential in our climate mitigation challenge.
13:02 | A UK based company called Brilliant Planet has perfected a method that, at full scale, can drawdown 2 billion tonnes of carbon dioxide from our atmosphere every year while also restoring alkalinity levels to our ocean ecosystems.
11:21 | Solar PV panels are multiplying at almost virus-like speed all over the planet. That’s a great thing for the transition to sustainable energy, but a massive potential problem for a catastrophically ill-prepared recycling industry.
11:36 | Research shows that the unwanted by-product of the mining industry, rock dust, could be a transformational supplement to agricultural soils all over the world.
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.
11:30 | Perovskite structures have the potential to revolutionise the solar PV industry, but they are notorious for breaking down very rapidly in real-world use. Now a research team from Princeton University has developed a process for overcoming that problem.
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.
12:17 | How do lifetime emissions from manufacture, transport and disposal of renewables stack up against fossil fuels?
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.
12:06 | A new report shows how much more economically smart it would be to simply jump straight from coal to renewables and cut out the ‘natural gas middle-man’ completely.
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.
12:30 | A new study proposes copying the way nature creates seashells, so that we can durably store billions of tonnes of carbon in solid rocks on the seabed.
13:53 | The latest IPCC report suggests we can survive the 21st century by making unprecedented and totally radical changes in the next eight years. But are they deluding themselves and giving us a false sense of security?
15:59 | Solar photovoltaic panels provide electricity for homes, businesses and utility scale grid providers. Ironically though, the hotter they get in direct sunshine, the less effective they are at producing power.
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.
15:49 | Can we survive the coming decades? The IPCC has just published their answer, at least from a climate point of view. And they pull no punches.
13:24 | Balancing renewable power sources on modern electricity grids is becoming one of the greatest logistical challenges of our time.
15:59 | Algae has been used by humans for thousands of years, but the idea of using algae as a secret weapon to combat climate change is definitely a modern day concept.
12:16 | Solar, wind and wave power from a single offshore platform?
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.
