This will need a bit of regulation and industry standards, but would be worth it, small changes to home power management systems and EVs, some of which can be implemented with firmware changes and updates, the rest is up to the smart new grid.


Vehicle To Grid: Is the Future of Energy in Your Garage?

Vehicle to grid V2G allows you to get paid to send charge from your car battery to supply the grid. I’ve been keen on V2G ever since I first heard of it. It feels like a two for one deal: you buy a car and you effectively get a home battery as a bonus. And on the society-wide level, we roll out electric cars to clean up transport, and we end up with a solution for some of the biggest challenges of an all-renewable electricity grid.

The fact is that cars spend most of their time parked. A fully charged EV battery can power a house for several days. And even though a car battery sounds small compared to a whole electricity grid, together the potential is huge. If all of Australia’s vehicles were electric, the total storage would be vastly more than any grid scale battery like the Hornsdale Power Reserve’s 'Tesla Big Battery.' In fact it would be over three days worth of the current electricity consumption of the National Energy Market and five times as large as Snowy Hydro 2.0 and with far fewer delays and cost blowouts.

I’ve covered V2G before, when I visited the Australian National University to talk about their research project Realising Electric Vehicle-to-grid Services and in that video I asked the question: if V2G is so great, why aren’t we already doing it? Well, today we’re going to take a look at a few home and small business projects that show that V2G is moving beyond trials—it’s now a real-world option for households and small businesses.

Today, in South Australia, we're visiting real-world installations to see how it works and to hear the experiences of the owners. South Australia is the perfect place for this video for two reasons. First, their electricity grid has the highest proportion of variable renewables in the world, at 70%. And they plan to be at 100% and even beyond within a few years. This is great for electric vehicles because not only are there no tailpipe emissions but there are no emissions from power generation either. And it raises challenges that V2G is well placed to solve. The second reason that South Australia is the perfect place to film a video about V2G is that it’s the only state in Australia whose grid allows it. And in fact there aren’t many other places in the world.

Thanks to MG Australia for loaning me an MG ZS EV to drive around and film this video.

They had better be cheap because China and other Asian countries will be making cheap ones that are already being sold in Europe and South America as well as Asia. Xi is on a diplomatic and economic offensive and part of it is breaking into the global car making market with the transition to EVs. The future is hard to predict though with the increasing use of automation labor becomes less of a cost factor and better cheaper new batteries could change everything in the EV market, so could solar recharged compact cars.

One can see why many people are reluctant to convert to EVs when you look at the costs, choices and weight of current battery packs. However, this is due to change over the next 5 to ten years with better batteries. LFP batteries are not as energy dense as Li-ion cells, and they have problems in cold weather, but are not as much of a fire hazard.

Good reasonable article. Washington complains they've not heard "reasonable arguments". Apparently reasonable is in the eye of the beholder nowadays but I'm interested to see what Buttigieg has to say about this. We don't need another budget airliner to join the race to the bottom. There's too many areas where noise levels exceed the amount allowed by law, making large swats of land in the otherwise most expensive and best area of NL unavailable for much needed housing projects. That, and nearly 4% of total carbon emission and 10% of total nitrogen emission (of industry), which makes it a primary target in regards to emission goals. There was once a big plan to build an airport on sea, just before the coast, hyper speed connections to Amsterdam. Not reclaimed but claimed land sort of speak. Pricey option, but would have solved a lot of problems. After years of procrastinating and reluctantly letting Schiphol grow, it's no longer a viable option, the sea is full too now, with wind parks, nature, fishing and gas mining areas and busy shipping routes.

I figure and so does the EU, that high speed rail is the best option for a lot of shorter trips inside Europe and the faster they go the better. China is leading here with maglev technology to really compete with airlines for a lot of routes under 2000km and going to the city center instead of kilometers outside of it.

It is, and it’s nothing new either, oldest hsl in NL is from 2009 already. But this isn’t sim city and we didn’t just recently colonize the place so there is billions worth of infrastructure and structures in largely urbanized areas in the way. Curves, tunnels, bridges, kill HSL travel times. In many cases they never reach the promised speeds cause it literally tears up the infrastructure. Aside from all the obstacles that need to be overcome to implement such an alternative physically, flying is much cheaper and much faster. ( Also why we don’t need another budget airliner. ) Many railway and train companies are (still) partly owned by governments and there’s always some level of protectionism and a lot of politics involved. The EU is in this context more a thinktank than a political force that can actually achieve their utopian ideas. In the end it’s still dozens of different nations each with their own ‘ways’ and own economic interests and varying politics that need to work together.

The current hsr lines are concentrated in the west, and while those are nice in theory in practice contain so many gaps and bottlenecks it’s more for people who hate flying or busy airports. Given the growing population and younger generations feeling more european and more often wanting to work and study across the border, HSR is a needed addition. It not a solution to the problems now, will take 2-3 decades to complete.

They might make an exemption for short haul electric aviation, because other than EVs and trains I don't see a way of getting people where they want to go. We are likely to see electric aviation before highspeed maglev in Europe, we aren't there with the batteries, but from the work I'm seeing it shouldn't be too long before they start arriving. The current generation of Li-ion batteries won't cut it for EVs or aviation and we need much more power density and lower costs. For most of the planet solar appears to be the solution, we just need the storage to make it happen.

Normally I wouldn't post something like this, too good to be true, however...

It would help if they explained the process more, or at least the theory, other than it's been validated by a third party there isn't much to go on. Big players in the energy industry and countries should be keenly interested in this development. That's if there is anything to this, I would expect much more interest and patents in the coming days and weeks. There is just too much on the line here and too many financial futures at stake for something like this to go unnoticed for very long.


Nuclear fusion capable of 500% energy return using water - game over!

This where the however part comes in, if this is real, then we will be hearing more about it quickly I would think!

If it is producing neutrons, they should all be dead after the test! This video was released on Oct 25th, you would think we would hear more about it in those 10 days, if it is as these people are "advertising".

Cold Fusion is Back (there's just one problem)

In the past couple of years cold fusion has received renewed attention, though it's now been renamed to "low energy nuclear reactions" or LENR for short. In this video I look at what we know and don't know, and how promising it is.

A bit more on fusion research, one of these outfits has a contract to supply power to Microsoft by 2028


Despite this technical hurdle and others, Helion lined up its first customer for a power plant that it says will go on line in 2028. The company recently finalized an agreement with Microsoft to provide at least 50 megawatts of electricity—enough for a factory or data center—after a one-year ramp-up period.

Many in the fusion-energy community dismissed it as a publicity stunt, or at best an overoptimistic reach for a company that has yet to demonstrate a net energy gain from its reactions. But these days, optimism is growing in an industry that is racing to solve the climate crisis—with or without neutrons.

More information on the fusion claims of ENG8 about 5 times energy out than in, if so, it would not be hard for them to demonstrate infinity by the thing self-powering itself and producing excess energy too. Perhaps if they did that people would take them more seriously? If this is anywhere close to real, it is of course Nobel prize territory and scientific interest should be keen over the coming days and weeks. The last fusion claim from South Korea was debunked by the global scientific community in a week or two and this thing does not look hard to duplicate from the information contained in this blog post. Things can happen fast in science these days and verifying this is one of them.

Meanwhile if fusion doesn't work out solar is getting cheaper and we haven't even entered the age of really cheap solar with the recent introduction of perovskite solar cells. Currently prices are in the 60 to 70 cent per watt range for all the major types of PV panels, that is the cheapest watt of electric power by any means and IMO it is about to get far cheaper, so cheap that a lot of silicon panel makers might go out of business.

Probably a long way from the lab to the fab, however it shows what is possible and that we might not necessarily face bottlenecks in materials. Any home battery would need to be fireproof for insurance purposes IMO and if it can't burn it should be ok for use inside the home. We are likely to see sodium batteries for home power storage before Aluminum Sulfur batteries.

I'd like to see more validation than UL labs! Though they did put their reputation on the line I suppose. This would clearly be Nobel prize territory folks so expect some serious scrutiny of their claims and attempts at duplication over the next week or two. Such claims don't last long in today's global scientific environment before being disproven or not. As yet it does not appear to be taken seriously by the scientific community, but if it is, then it will soon be put to rigorous tests.

A lot of that money was from gasoline sales that won't be there in a decade and a rapid decline after that, where the market for gasoline goes a lot of diesel fuel is bound to follow. Governments give these guys billions in subsidies every year.

Green technologies are disruptive technologies and will cut into the profits of utility and oil companies, putting some out of business, like coal mines.

I would look for more of this as "energy independence" movements arise with the increasing number of prosumers generating and storing their own power, along with a smarter distributed grid. Solar generation now costs less than 70 cents a kilowatt and prices are expected to drop much further, soon storing it will be economical too. It doesn't make any sense to pay 15 to 20 cents a kilowatt for it from the grid when you run your home and transportation on it and can sell back excess to the grid. It makes sense if you heat your home with electricity and are charging up an EV overnight, then the kilowatts used go up quite a bit and so will the power bill. If the grid doesn't operate the way you want, organize and vote to make it a coop or nonprofit utility using the power of the state and your vote.
