How Can We Store Excess Renewable Energy? | Engineering The Future

[@bartz0rt928]

What's missing here in my opinion is discussion on how to adapt the demand side, like building houses in such a way that they don't need as much cooling and can stay cool for longer (so you could run the AC during the day while the sun is out, and then not need to during the night because your house "stores the cold"). I notice that a lot of modern houses (especially in the US) don't even have retractable awnings! Storing energy always incurs losses, so you want to organize everything to minimize the amount you need. You can do that with demand response (basically, telling things that use a lot of energy to wait for a bit), better interconnects to make sure the electricity can be sent to where it's needed, and ensuring the optimal mix of different energy sources (there's more sun during the day and in summer, and more wind at night and in winter).

[@forgotten6411]

there is no good solution to store "cool", since if you want to have storage of this, you will have to cool even more, than you need, for the "future demand". But, all the technologies are already existing. Just check european solutions. If I mention all the technologies, applied there in order to build energy efficient house, I will not have enough space for it in this reply. But the first thing - insulation. In Ukraine, for example, good houses have 1 meter wall thickness. And after that + 10 cm insulation material. This will significantly reduce the demand for cooling in summer and heating in winter.

Pumped storage is the way to go. They last for generations with lower replacement and maintenance than other storage methods. To combat the problem of needing to source them along a possibly drought stricken river, we should incorporate sea water desal & pipelines, so that these can be placed more easily without disrupting natural waterways. This is how you can fill and compensate for evaporation even in drought.

My solution is to have a balanced grid to start with. Use the excess power generated to power desalination plants and brine processing plants. From the sodium extracted you manufacture sodium ion batteries on a large scale. With enough batteries made you can build industrial scale power storage and transition to 90% green energy in time.

[@deepmodak7682]

Why these not constructed fully!

[@rdasarihyd]

What would be the cost of such systems vs traditional?

[@francoisbadoux625]

The cost of Pumped-Hydro Storage (PHS) is $50/kWh of storage capacity for a relatively easy to build project, to $110/kWh for the most expensive projects in the Swiss Alps (the Nant-de-Drance project, commissioned in 2022 in the Swiss Alps, has cost a total of $2.1B for a storage capacity of a bit over 20 GWh and a generating power of 900 MW)! In comparison, the installed price of battery storage is presently $350-500/kWh. Furthermore, the PHS system has a lifetime of over a century... and the battery one of 20-25 years!!! So, a PHS system is nearly an order of magnitude cheaper by unit of energy storage, than batteries.

[@alberthartl8885]

The winner in long duration storage is not yet known. Two promising technologies that are not site specific are iron air (Form Energy) and nickel-hydrogen (EnerVenue). These batteries need to be paired with fast reaction lithium ion to maintain grid synchronization.

[@donmcgimpsey1706]

I think tidal/wave power is the best battery charger in this scenario. Tides go up and down, and lift entire fleets of battleships, so why not lift large sand-filled concrete bins. Make everything container sized so you can leverage some existing gantry cranes (Increase the lift capacity to 100T+). I know there are a lot of negative arguments, such as "Only good in coastal scenarios", or "Tides only go up 5-6 feet" - you just need difference in height, you can leverage gears and pulleys to convert to height (same). Think of the potential energy of a supertanker lifted 10 feet in the air.

[@st-ex8506]

My point... unfortunately rather negative... but I wish it was not as your idea has some merits... is that to equate the storage power of the Linth-Limmern power station featured in this video, you would need over 300'000 battleship-sized sand-filled barges being lifted by tides 5-6 feet ! You'll need SOME anchorage site! I also think of the potential energy of a (full) 500k ton supertanker being lifted 10 feet in the air: it is precisely 0.01% of the storage capacity of this Swiss pumped-hydro site! A gnat's ass! OK... I agree that the supertanker will be lifted by the tide twice a day, while the pumped-hydro site goes through only a single daily cycle... so... 0.02% the daily storage capacity!

Thank you for this presentation. You address the issue well, but you only briefly mention "behind the meter". The issue is that the power grid is becoming decentralized and bidirectional. NREL predicts that one third of electrical generation and storage will be on the consumer side. My interest is in grid forming battery/inverters. Substations will become independent nodes and will be responsible for power conditioning.

Are you sure that iron flow batteries are cheaper than lithium ones (per kW)? My information goes clear against this statement. However, you are right to say that they can economically provide longer storage, as all you need for that are additional tanks.

[@douglasengle2704]

Solar voltaic and wind turbine generated electricity causes the most expensive and unreliable electricity in recent history. It produces wild AC which is not power grid quality. Making solar voltaic power grid quality means using high availably other sources of electricity which is typically natural gas turbine generators running at high service idle consuming 70% of the fuel it would at full throttle when making all the electricity needed, but no electricity at high service idle. This is what is required in order to make up when a cloud passes over a solar farm. The sorry story is California saves surprisingly little natural gas with all the solar voltaic panels it has, but it does have to buy the nearly worthless wild AC at many times the cost of generating grid quality electricity internally passing those cost on to consumers, but not enough to keep the power grids out of bankruptcy. California has to buy all the wild AC. That is why it has to pay to make it grid quality to sell it for whatever it can get for it just to get rid of it when it has an over supply to other power grids. Non peak load power goes for wholesale prices of about $0.03 per kWh. The SoCa power gird has to buy home solar power whenever its available at retain prices of $0.35 - $0.50 kWh. It then has to spend a lot of fuel to make it power grid quality. Cumberland Indiana had residential electric rates of $0.10 kWh in 2020 a suburb of Indianapolis.

[@krslavin]

Huh? The quality of power at any one time is the same from any source - the voltage is the same in all cases (only cheap gasoline generators produce non-sinusoidal output), but the amount of current and power it can generate may vary. California is rapidly building its storage using Tesla Megapacks, which actually provide a much cleaner and more stable grid, as they can respond rapidly to varying loads.

[@st-ex8506]

Quite at the contrary! Wind and solar PV power are now the two CHEAPEST means of electric production... even if you add the necessary storage! Solar + Wind + Storage can cover 100+% of the needs of all countries and regions up to the polar circles! Source: RethinkX Energy Report.

[@JohnKite-v3p]

The problem with the storage of energy points to the problem of congestion caused by curtailment that occurs with intermittent variables. The solution for a constant and variable energy source is using a solar hydrogen energy recovery gas turbine as a constant variable. The process uses the suns nuclear fusion that has a 5-billion-year supply of solar energy to produce hydrogen which is the most universally inexhaustible abundant of elements. This hydrogen is than used to generate a higher, more stable energy output up to 1300Mw but governed between 86-330Mw to manage grid stability and avoid renewable energy zones. The process is similar to a nuclear fusion reactor. However, instead of achieving nuclear fusion at extremely high temperature (150 million degrees Celsius) this system achieves and maintains Ignition at much lower temperatures. It doing so it uses an energy output that exceeds the energy input required to start and sustain the reaction. The operating complex requires an area the size of a football field. The hydrogen power generating turbine has three operational parts, 3.0m in diameter 5.5m long weighs 6 ton has a 14-year continuous life cycle and incorporates direct air capture of CO2 at 1,400 Kg/sec. The cost is $36.5 to 49.5 million being significantly less than an equivalent 330Mw nuclear reactor, solar or wind farm.

[@Vitan89]

Where did you find this fantasy invention? Gas turbines are at most 60% energy efficient and electrolisers for solar are around 50% efficient. So for 1kWh of "hydrogen turbine" electricity you would need to input almost 4 kWh of solar. So that cheap 40$/MWh solar energy suddenly turns to 200+$/MWh. This is why practically no one wants to buy green hydrogen...

Now that we are experiencing extreme droughts and heavy rains, pumped storage power generation will likely reach its limits. I'm an electrical engineer and have an idea for a gravity power generation system that takes into account cases where solar and wind power generation is low. Because Japan has many earthquakes, this idea envisages sending electricity to a minimum number of institutions such as hospitals and government offices even if there is a power outage after a disaster. I think California would be suitable as well, as there is a risk of earthquakes in the country. I previously approached Mitsubishi Electric about collaborating through the Ministry of the Environment, but have not heard back. I now think it would be OK to disclose this idea to people in other countries as long as they are in a trustworthy position. Icon's device is a self-funded and patented passive cooling device.

In 1976 Britain we had the biggest heatwave for 3 months. I was 6 years old and remember it well. Imagine if that was today. The media would be having a fit. This year in Britain it has only been nice for the last 2 weeks and other than that it has been a real cool spring and summer.

« More energy storage in the grid » etc …..is WHERE the mental blockage of electricians starts…: energy means power generated at a given place and time to the power charges, all kinds, stationnary, domestic, commercial, industrial and mobiles for transport. The link, the grid, the network, the distribution of power between energy supply and energy loads AND the load charges as well…Diesel, Ev or H2 vehicles for instances have to be BOTH adapted to new powers generated and the new powers supplies, NOT THE REVERSE…adapting the power supply and network to this huge new heat pumps and BEV additional loads for instance…this require way too much polluting grey energy: if all this supplemental power MUST anyway BE renewable for the salute of the planet, then a specific power distribution and adapted loads population must be optimised for low economical cost and low grey energy, good sociability and biospheric compatibility…For instance, when railways were electrified due lack of coal and inefficiencies, our wise predecessors did no put a resistance in the boiler and a pantograph on the cab of steam locos to find out there was three time not enough hydroelectric energy to power such poor steam cycle…No!!! They produced efficient electric locomotives converting directly E-Power into displacement….and NOW it would be ABSOLUTELY insane if surface renewable solar and wind power is present all over and abundant (solar radiation amounts to 1500 times all the humans power consumed and wind almost as well), to transport this energy elsewhere with powerlines joules losses or pipelines friction losses to another place where it could also be produced!!! This clean energy must be stored and distributed (not transmitted) where it is produced AND the mobility loads, huge and with long range storage capability must be loaded at specific locations to balance the system with a competitive offer and demand fair market and a single real time android apps…..this is where fuel cells and combustion of renewable synthetic zero CO2 gases, H2, CH4 and NH3 easely stored, compressed , liquified locally where needed can replace an ugly power network and cumbersome electrochemical reversible chemistry of batteries, which is dirty, hard to recycle and not endurant nor durable enough. Synthetic gases energy is used with with much LESS grey energy than massive copper aluminium network and lithium storage mining nonsense plus lake evaporation wastes…for instance storing a full season one kWh of H2 in a COPV bottle with zero energy loss cost hundreds times less than storing a similar kWh in a most durable LFP battery only a few day with joule losses: one is adapted variable seasonal unpredictable renewables, the other not !!! Then, the selected renewable system efficiency is not the major issue (essentially a foot print issue only) because sun and wind are free of charge so the major cost is therefore the grey poluting energy of a still dirty civilisation . The real issue per MJ or kWh provided at the right place and right time is the COST and planet impact of that power provided,,while anyway system losses such as high enthalpy heat and pure oxygen have also good commercial values all year long for heating cooling hot water medical,welding etc.. At the same time, without ONE unique electrical and ONE gas nerwork and the same fuel at all gas stations etc, this marks the end of a monopolistic stronghold of the very few biggest fortunes of this word on energy ressources and energy supply at retail level, monopoles finger printed by the huge gap from production cost to retail selling price. THIS is what the current power network and fossil lobby is NOT giving up and willing to kill the planet instead, with all sort of abusive arguments for naïves politicians : nuts aren’t green but our green are nuts! 😂

[@sandorski56]

No.

[@beyondfossil]

No. We're more ready now than ever for renewables. Firstly, some context. The huge cosmic power of the sun can power the world some 10,000 times over at least. The sun provides the Earth a massive cosmic 173,000-terawatts of non-stop clean fusion power continuously for billions of years and at least a billion more. For reference, 173,000-terawatts is enough to provide all 620-exajoules of energy we use in 1-year in just 1-hour. Or just averaging just 1/10000th of that power spread over a year across the world would provide all we use now. The sun is 99.9% the mass of the solar system and the Earth is like a small breadcrumb next to a large watermelon as the remaining 0.1% of mass is mostly Jupiter and Saturn. There is no source of power even remotely close to our sun within over 4-light years from here. All the combined fossil fuels past, present and future would amount to *a bucket* of water in an ocean of water in comparison -- a bucket! Secondly, the global fossil fuel industry has convinced you that there is an energy shortage but there isn't. It's a classic abusive relationship where the abuser has convinced the abusee that he/she cannot live without the abuser, but no. Some combination of sunshine and wind is available everywhere on Earth and these raw inputs cannot be blockaded, taxed, sanctioned. Less than 1% of the world's land surface covered in just current generation photovoltaics can power all the world's grids. There is enough offshore wind to power the world several times over. Thirdly, renewables have reached historic low cost per watt hour of generation and continue to drive ever further lower in cost, especially photovoltaics. In 2022, over 80% of all new energy additions were renewables, mostly photovoltaics and wind. Finally, the next 10- to 20-years will be critical to avoid the worst of climate change. There is no time to lose. For this and many other reasons, we need to stop drilling as quickly as possible. Renewable green energy is not just a solution, it is the only solution that will get us out of the energy crisis and onto new levels of civilization only dreamed of. The renewable energy systems of our successor will make the current energy systems we have now look like a child's bedroom toy set.

Hydrogen.batteries are dirty not green

[@DobleWhiteAndStanley]

... by storing the excess energy in homes... Seriously. Its not that difficult to add a battery bank in a home to store power in off times like at night when solar doesn't work, or in the doldrums when wind isn't blowing... Its decentralized, meaning you don't waste money with having to over regulate it and hiring government middlemen to be trained and train others, and handle the ridiculous and superfluous paperwork that could have all been circumvented by just... Doing it privately. Decentralize it.

We can’t store meaningful amounts of energy for meaningful amounts of time which is why alternative energy is the most inefficient and expensive way to attempt to power a nation. All alternative energy requires fossil fuel or nuclear back up these systems must be running so you get expensive duplication of energy systems. It’s pretty nuts and isn’t going to make a dent in changing any climate patterns real or imaginary!!
