Yes, it could be used to provide low grade heat. Particularly in remote areas. Whether it is cheap enough is not clear to me.

Not sure that their are not lower cost ways to generate low temperature heat. By the way something not mentioned much is nuclear fusion. Once nuclear fusion (mimicking solar reactions of the sun on the earth ) is proven commercially removing enfvironmental and other issues that plaqued fission reactions alot of the issues of the 24x7 dispatchable renewable energy grid go away by using some mixture of nuclear power and solar/wind . I beleive in the long term fusion will be a major source of our energy.

A number of DAC processes need heat either at or below 1000C. A small nuclear reactor should be able to supply this. If the requirement to raise steam and generate electricity are removed, the cost of the plant and the cost per KWH of heat should be significantly lower. Such an operation would not make sense in the early years of DAC but later when scale up becomes much larger and the world gets serious about DAC, then this could make sense. Look forward to comments and discussion. Swimming pool reactors had a good safety record (as far as I am aware), were not that expensive to build and were not terrible to decommission.
