Ovo Energy has launched a suite of domestic energy products, including a V2G charger that gives EV drivers the flexibility to draw electricity from the grid when it's cheap and sell it back during peak demand hours. And if users get the balance right, they could effectively drive their EVs for free.

Waste heat generated by electronics can damage components, and represents a large amount of energy going to waste. Now scientists at the UCB have developed a thin film that could be built into computers, cars or factories to capture and recycle the energy from waste heat.

Rather than using hydrogen in its normal gaseous state, a liquid hydrogen carrier called formic acid has been floated, and now a team from EPFL has built a promising prototype of a formic acid-based fuel cell.

Just a few months after Tesla built the world's biggest battery, another contender is looking to swoop in. Simec Zen Energy and British billionaire Sanjeev Gupta are planning to build an even larger storage battery in the same Australian state.

As useful as solar energy is, it still has one major Kryptonite: gloomy weather. Now, a team of Chinese engineers has developed a hybrid solar cell that can produce electricity come rain or shine, using the triboelectric effect to harvest energy from the movement of raindrops on its surface.

We’re so used to having devices powered by lithium-ion batteries that it’s hard to imagine using anything else, but there are plenty of alternatives. The latest, an aqueous hybrid capacitor, is stable, safe and boasts high energy and power densities, recharging in as little as 20 seconds.

Energy is all around us – we just need to work out how to tap into it. Now a team from MIT has developed a device called a thermal resonator, which could essentially pull electricity out of thin air by taking advantage of gradual ambient temperature changes over the course of the day.

Over the last few years, perovskite has proven itself to be a promising material for photovoltaic solar cells, but it’s not without its problems. Now, a team has found a way to helps solve at least one of those issues, removing toxic lead from the device by substituting in titanium.

Tesla is again partnering with the South Australian government, this time on the world’s largest “virtual power plant.” By installing solar panels and Tesla Powerwall batteries on thousands of houses, the system would allow homes to generate their own electricity and feed excess power to the grid.

What do you do when you have too much garbage but not enough energy? Convert one into the other. That’s the thinking behind the waste-to-energy plants that are beginning to pop up around the globe, and now the Government of Dubai has announced plans to build the world’s largest.
