Denmark Plans To Be Coal-Free In 10 Years

merbs writes "Earlier this year, Denmark's leadership announced that the nation would run entirely on renewable power by 2050. Wind, solar, and biomass would be ramped up while coal and gas are phased out. Now Denmark has gone even further, and plans to end coal by 2025.

    Russia has demonstrated that it is unwilling to engage in above-board transactions for their fuel exports. It is in every country's national interest to reduce dependency on imports when they can neither control the supply nor rely on the supplier to operate as a business rather than as a belligerent nation. If anything, Russia's recent behavior has reinforced this for Europe, and given the Europeans incentive to get off of Russia's exports.

    It's a shame that Denmark can't get off of natural gas sooner than coal.

      Thanks to the North Sea, Denmark is a net exporter of oil and natural gas. It's actually the coal they need to import. And compared to natural gas, it's actually the coal that is considerably dirtier. I personally don't see anything wrong with their plan. Few countries are in the position they're in, they will even benefit from what's going on with Russia right now.

      Or, you could use grid-scale energy storage, combined with low-loss HVDC long-distance transmission. HDVC lines can be over 2000km long, bigger than an individual weather system, so a network of them can redistribute intermittent wind and solar output effectively.

      Where are they going to get enough biomass? Farms aren't going to grow low value biomass instead of high value food.

      Food is biomass, and according to Wikipedia, half of all food - 100 kg per person per year - is wasted. Dunno if it would be enough to cover the need, but a low-cost, low-maintenance, high-reliability gas generator could potentially have markets, at least in apartment buildings, assuming it's actually possible to build one.

      "Renewable" energy requires natural gas in order to compensate for fluctuating output.

      That is true but not necessarily the way you think. In the long term the idea is to create substitute natural gas (SNG) from excess energy that would otherwise go to waste using hydrogen and CO2 for example with the Sabatier reaction. This is the same process Nasa is planning to use to produce rocket propellant on Mars. It's not a super efficient process but if you can harvest the CO2 from the atmosphere, you can still store energy that would otherwise be wasted and unlike drilling and fracking it's a closed cycle as opposed to a release of sequestered carbon. SNG it has the advantage of enabling you to recycle the existing natural gas distribution infrastructure.

      So do the alternatives. Coal causes billions of dollars of damage to the environment and people's health. Nuclear costs billions of dollars to build, and in the UK we have to guarantee double the normal rate for the electricity produced during the plant's lifetime. There is a third option, which is spending billions on efficiency improvements.

      No matter what we do we will end up spending that money, so the question is what do we want to spend it on.

      Having grown up next to a Danish first oil then coal powerplant, I can testify that some of the plants are actually dismantled while other have been converted to running on gas. One side effect of this was that many workers lost their jobs as a modern gas driven plant can be run by way fewer people.

      I believe the housewives of the town are happy though. When I was a kid they were always complaining that their laundry hanging outside for drying was getting dirty by the smoke from the powerplant and the dust from the trucks driving the slag away.

    Citing a study funded by a biased source is not very convincing. When Microsoft or a political party does it, they get chewed out by the crowd here, and rightfully so.

    That said, I'm fully willing to believe that wind power is cheaper than nuclear on a per-megawatt basis. What I don't believe is that wind power can reliably provide baseload power. All the studies in the world don't change one simple and indisputable fact: present-day production of wind power is miniscule compared to present-day electricity usage. Wind power has not yet proved that it can supply large quantities of power. Nobody except the most blind zealot would deny this plain fact.

    Nuclear power supplies one sixth of present-day electricity usage worldwide. This is a very large amount of power compared to any other carbon-free technology. Nuclear power is not directly subject to vagaries of the weather. Even including Fukishima and Chernobyl, nuclear power is by far the safest energy source (wind power comes in a very respectable second). Available supplies of nuclear fuel will outlast the lifetime of the sun. Nuclear power is proven and it works. Wind may work, and I'm happy to give it the benefit of the doubt, but it is without question an unproven technology at large scale.

    If you build something good in Australia it has a really really really long way to go before it can be consumed in the US.

    There is a reason why we produce large quantities or iron ore, copper, bauxite, coal, uranium, lead, zinc, and gold. It is because the primary consumers of those are close by (China and India).
