US Environmental Lead Says Advanced Nuclear Technology Critical to Decarbonize US and Japan (apnews.com) 265

A surprise from the Associated Press. The head of America's Environment Protection Agency "said Friday that advanced nuclear technology will be 'critical' for both the United States and Japan as they step up cooperation to meet decarbonization goals." Michael Regan, after holding talks with his Japanese counterpart Akihiro Nishimura in Tokyo, told a joint news conference that nuclear energy in their countries plays a role... "I think the science tells us that we have to respond to the climate crisis with a sense of urgency and nuclear energy and nuclear technology has and can have a role in continuing with a zero emissions contribution to the climate," he said, showing support for Japan's recent shift toward returning to nuclear energy.

Japanese Prime Minister Fumio Kishida said last week he instructed his government to consider developing safer, smaller nuclear reactors, in a renewed emphasis on nuclear energy years after many of the country's plants were shut down. Kishida said Japan needs to consider all options of energy mix, including nuclear, to bolster its "green transformation" effort to curb emissions of greenhouse gases and to secure stable energy supply. Japan has pledged to reach carbon neutrality by 2050.... While maintaining a 20%-22% target for nuclear energy as part of its energy mix for 2030, Japan's government had previously insisted it was not considering building new plants or replacing aged reactors, apparently to avoid stoking criticism from a wary public. Kishida's recent comment represents a sharp change from that stance.

Kishida asked a government panel to decide by the end of the year on its proposal for the development and construction of "new innovative reactors," such as small modular reactors, while also considering extending operational lifespan of aging reactors.

President Joe Biden also believes that it is an "all hands on deck approach," Regan said, adding that investments in nuclear technology and carbon capture will complement the big potential for renewable energy.

      We don't have storage systems to match the gigawatts of green power needed and the only projects I've heard of getting serious backing are in the megawatts of power range anyway (e.g. Biden's offshore wind) and without storage.

      Without storage we don't have base load power.

      Nuclear plants can provide base load power.

      By all means solve the storage problem but at present none of the means look that great. Un-recyclable batteries full of toxic metals ainn't the way. And no, Tesla has subcontracted the recycling problem out, they aren't doing it. The subcontractors are trying to come up with a way to do it while taking investor money. It's absolutely an unsolved problem.

              In the same time frame, you can steadily build thousands of new wind turbines at a cost of 0.5 to 1 billion USD per GW of capacity.

              You also neglect the billions of dollars in transmission line upgrades needed to get from where the renewables are generated to where people actually live. That capacity factor of 20% still needs transmission capability for the entire 100%, because you never know where that 20% is coming from.

              It doesn't matter if you need backup power for three days of the year when there is a large scale Dunkelflaute event as it will still be a much better situation than the status quo.

              It does matter because nobody is going to build (or maintain an existing) base load plant to run 3 days a year.

          • Why? Do they turn the wind off at night?

            • Yes, they do. Wind drops off around midnight and starts up again, maybe, around 10 am.

                Germany has no place where wind would stop at mid night.

                And I really doubt you have one :D

                Looking at your green line, the wind "stoped" - once. And was a bit low end of August.

                And that is not the wind curve anyway: that is the curve of power provided by wind, facepalm.

                Strange that the wind power fed in was pretty high two times at midnight. Odd behaviour for stopped wind, if you asked me.

            • Wind is also intermittent. Do you really think the wind blows every second the sun is not shining?
          • You must be living at an odd place.
            Germany does not need storage at night, nor does UK, or Denmark.

          Wind turbines out where it's extremely windy have capacity factor of 0.52, that means half the time the wind isn't blowing there. Here around Chicago area, the 'windy city', it's only 0.30

              Let's assume there are wind turbines distributed over most of the USA. Let's also assume that from wether data we know that the worst case factor between predicted energy production and momentary production is 30%, i.e. only 30% of what would normally be produced by wind turbines is actually produced.

              There are very much systemic effects in space and time including time of day, seasonality, storms and high pressure systems with massive implications for grids dominated by wind in terms of over provisioning and energy storage schemes.

              The easiest approach is (1). Natural gas engines are fast to start and low maintenance. Given the environment models we have, we could cut the fossil fuel emissions by at least 95% using this option alone.

              Not even close. Even if you were able to build out 100% wind capacity (~10x present day total wind install base) and magically snap your fingers upgrading transmission systems to handle huge long haul energy flows then only 30% of annually averaged electrical power would be provided by wind. The rest would have to come from somewhere else. There is no universe in which this translates to a 95% cut of fossil fuel emissions.

              Ultimately, we will end up with a mix of all three factors short term.

              More like forever. The most credible solution to support energy mixes dominated by intermittent renewables requires long haul transmission, storage, over provision and something like nuclear. These issues are full of non-obvious non-linear relationships.

              The right balance between (2) and (3) will depend on questions of intelligent load management and raw price.

              Nonsense.

              But it is also way more important to accept that just building renewable capacity at this point is much more important than worrying about storage capacity as we are nowhere near 100% realistic production capacity yet.

              Even with relatively small overall contribution wind and solar are already triggering stability problems in the real world. This will only grow as proportion of intermittent contributions increase without storage.

              So any discussion of "we need storage" is a distraction from the necessary way.

              It cannot be ignored.

              Nuclear also has the very same problems from the other direction: because nuclear plants do not like reducing the load, mechanisms for smoothing out the peak energy use apply just as well to them.

              Without ~20% nuclear people are still likely to keep burning boatloads of hydrocarbons so everyone should make up their mind what they care about more.

              The reason for this are the concurrent effects of diminishing value of over production and *exponentially* diminishing effect of storage. Here normal present day price tags measured in terms of LCOE are worthless.

              Perhaps it can be avoided thru technology who knows fusion, economies of scale, unexpected advancements, increased capacity factor thru increased hub height, airborne wind systems, magical flow batteries or some shit. Who knows but right now nuclear is required and wind is a fairly mature technology.

        • Storage isn't critical path, but for continental-scale wind to have 99.99% availability you would be looking at capacity factors around 10% best-case. That makes the $50/MWh electricity suddenly $500/MWh just in terms of turbines, and then you need to significantly expand trans-continental transmission to harness the energy.

          Nuclear is likely cost-competitive at anything over $120/MWh, maybe even as low as $100/MWh.

If there is one thing that would take more time and is more expensive then new Nuclear Plants, thousands of miles of new high-power transmission lines would be it.
          • by jsonn ( 792303 )
            For the price of one new nuclear power plant, you can build two high voltage lines connecting the East and West coast. Don't get me wrong, redesigning a grid like that is not an easy or cheap process, but the alternatives are no better. There are already enough reasons for why extending the grid is necessary. Let's just look at Texas for one of them. More nuclear power plants won't fix the problem either since you still need the transport capacity to deal with local events like a drought or frozen rivers in

          Impractical. How many do you need operating at capacity to achieve 1TW? What do you do when they're not at capacity? What do you do when it's not even windy? What's a "solid base capacity?" Does it meet our needs or not? How many birds are you chopping up, and how much waste are all of those going to cause?

          Nuclear is a known quantity, practical and reliable. Large wind farms are fantasyland.

          • by jsonn ( 792303 )
            On-shore wind turbines are currently typically around 3MW, so for 1TW it could 350,000 turbines. If you build them in a straight line from the East coast to the West coast, that would be one wind turbine every 20 yard. That's nothing at all.
        • You don't need storage systems for a long time. Seriously, it's a red herring.
          Wind and solar cost a fraction of what new nuclear power plants cost and can be constructed in a fraction of the time as well. Get to 80% of energy production using renewables first before worrying about storage requirements to get to 100%.

          It doesn't matter if it is 30% capacity factor or just 20% - even at 20% it will be more cost-efficient than going with new nuclear plants. There is no need to aim for perfect right now, building out the grid and covering the good spots is good enough to solve a huge part of the problem and reducing the actual cost of energy at the same time.

          These are quite extraordinary claims. Did you do the analysis yourself or are you relying on existing studies? If so care to cite any?

    If you have been paying any attention to the way energy is produced, to the materials needed to make new solar panels and windmills, to the supply of all forms of energy now and going forward... the only conclusion you can reach is we need a lot more nuclear plants, as quickly as possible.

    We should be basically outlawing the shutdown of any nuclear reactors, for a start, as the replacement of them is a massive amount of extra CO2.

    But more importantly we should be fast-tracking new nuclear technology, and the production of other well-known designs immediately, in every country. It means cutting through regulation that would slow construction, and immediately saying anywhere that is a coal power plant now should be turned into a new site for a nuclear plant ASAP. That way you are eliminating pollution, while providing for the people who have kept power going for decades now by bringing them new jobs in construction and plant management.

    If you are not in support of that you really are not supporting any movement forward on CO2 reduction. There is no other path possible, so the only other position is outright failure.

      Makes no sense. The EU is still in the early stages of ramping up renewables. The end result will be a couple of orders of magnitude more renewable energy than it has now.

      And in any case, the issue in the EU is the scarcity of gas, not electricity. Electricity prices on rose because some of it is generated by gas, which is just more incentive to move away from fossil fuels. Also most heating is gas, which again creates an incentive to move to electric heat pumps instead.

  • Something to consider when this was looked at years ago is it was found that wind in the USA needed to be backed by natural gas fired power plants to compensate for the rapid shifts in generation versus demand. This backing ended up being 89% of the power generation came from natural gas and 11% came from wind. It was estimated that if a full battery setup was added, the share of wind power could be raised to 22% with the other 78% coming from fossil fuels. For solar I went through a study done by Sandia
