Germany Finances Major Push Into Home Battery Storage For Solar

mdsolar writes with this bit of news from Green Tech Media "The German government has responded to the next big challenge in its energy transition – storing the output from the solar boom it has created — by doing exactly what it has successfully done to date: greasing the wheels of finance to bring down the cost of new technology. ... Now it is looking at bringing down the cost of the next piece in the puzzle of its energy transition — battery storage. ... KfW’s aim, according to Axel Nawrath, a member of the KfW Bankengruppe executive board, is to ensure that the output of wind and solar must be 'more decoupled' from the grid. ... This is seen as critical as the level of renewable penetration rises to around 40 per cent — a level expected in Germany within the next 10 years. ... According to Papenfuss, households participating in the scheme will spend between €20,000 and €28,000 on solar and storage, depending on the size of the system (the average size is expected to be around 7kW for the solar array and around 4kWh for the battery)."

      No it isn't. The grid is many power stations tied together. There have been incidents where that interconnection itself has been a problem due to ripple effects of one power line failure (e.g. the Northeastern blackout of 2003), but that's technically solvable. As for local transmission line failures, the problem is poor practices (overhead lines instead of underground) and poor maintenance (e.g. lack of tree trimming near overhead lines). Most countries spend more on power line maintenance than the US, and it shows in the reliability. In other words, to the extent our central power station system is unreliable, it's because of penny pinching and politics, not technical barriers.

      "Off the grid" is a pipe dream for most people. While household solar and batteries move towards that goal, the solar won't be enough to cover all power needs. That's especially true in, for example, apartment buildings. On the whole, greater use of renewables will require greater interconnection than what we have now. I applaud the German household solar approach, but Germany doesn't have anything like America's Southwest. A lot of solar can be generated there, but it takes long distance transmission lines to get it to people in less sunny climes. Similarly, the Midwest is an ideal place for wind power, but again you need transmission lines to get it elsewhere. These transmission lines are also important because of the unreliability of many forms of renewable power. It may not be windy in one place on a given day (or number of days), but it's rare for the wind to not be blowing everywhere. Hence you transmit the power to even things out. Hydro is another, and definitely the oldest case, of renewables requiring long distance transmission lines. The Pacific DC Intertie ships 3.1GW from Northwest hydro plants to SoCal. Much of the Northeast gets power from Hydro-Québec, which has 60 hydro plants generating an astounding 35.8GW.

For wind and solar power, the power is available when it's available, and you can either consume it, store it, or waste it. Ideally you'd have a proper smart grid (not the kind that's being marketed, which is just a power meter with WiFi) so that you could have things like fridges and freezers run their compressors during supply spikes and leave washing machines and so on programmed to run whenever there is surplus power. In the absence of being able to trigger demand when you have supply, storing it inefficiently is probably better than wasting it.

      That said, the majority of my electricity consumption when there is no solar power available is lighting. It would be great to have a DC main with a relatively small battery that could power LED lights overnight. It would probably also let me charge electronic devices more efficiently than going via DC.

    (Batteries for -local- storage of electrical energy might be good, eg, as anything that disconnects one's home or office from mains power is a problem almost anywhere.)

    In a post-Fukishima world, the EC - if not [also] Germany - should be investing in Energy from Thorium (eg, developing improvements of its proven technology from the 1950's, which even Germany has successfully trialed in the 1960's or the 1980's, I understand).

    For many of the reasons (ie, features), cf Prof Dr Eduardo Greaves' [36-min.] talk "Thorium as Nuclear Fuel in Molten Salt Reactors" (on YouTube.com). (The impatient can search TED.com for Sorensen's 10-min talk & view at least its last 5 min's.)

    R&D should run in parallel with Education & Debate, in the hopes that the Public will soon "get" that there are several types of reactor, some (eg, Liquid Fluoride Thorium Reactors = LFTRs) being much -safer- than Fukushima's reactors proved to be.

    We should all understand the differences between even Canada's (long ago) improved CanDo reactors (still in the same "safety class" as Fukushima's, I understand) -and- LFTRs, which are expected to be not only "walk-away safe" but also cheaper to build & run.

    After people come to understand the significant differences & inherent advantages in the design of LFTRs (and their safety levels are verified in ways that give all peoples confidence to embrace them, even near their back yards), we'll be able to make another great stride in our energy technology that can enable us to:

    1. reduce CO2 emissions, & also turn back Climate Change that appears to be caused by it

    2. enable any & all nations to build & use LFTR-technology - instead of current Plutonium-producing reactors, that we limit today

    3. reduce the amount & cost of spent-fuel storage, eg, by consuming that fuel & getting energy from what was once waste

    4. reduce or even eliminate "oil wars"

    5. enabling us to -stop- "fracking" for Shale Oil &/or Coal-Seam Gas (CSG), which destroys water & land resources

    6. reduce internal conflicts within nations (eg, legal battles & protests over "fracking")

    7. redirect our minds to innovative & exploratory projects, in Science, Medicine, Space, Community Development, etc.

    I see only win-win's from Energy from Thorium... are there any risks or disadvantages?

    Let the debate continue, eg, in you comments & replies.

    I disagree with solar panels, and Bill Clinton's subsidizing mortgages for single family homes. The average person can't tell between good house construction, and poor house construction. So, homebuilders build big, shoddy houses, that impress the average person, which he can afford, thanks to federally subsidized mortgages.

    Instead, smaller, well insulated condos in the city, would have been a more energy efficient way to go. Maybe throw in some light rail. No more damn lawns to worry about.

    if they had decided to support the electric car. But German car makers are behind the competition in that field, so they made sure the government they elected keeps pushing the combustion engine. Why should anyone install stationary batteries in their homes? It's not like we have blackouts all the time. They should work on keeping it that way by investing in infrastructure, instead of relying on home owners.

    Fracking was invented in about 1900

    Radio was invented around then too, but the technology and its applications have changed a lot since then. The modern fracking techniques were developed by government funded research in the 80s and given for free to industry. Just look it up; it's easy to learn about.
