Th co2 emissions from steel used by the turbine are tiny compared to the co2 avoided by building the turbine. So it is still a big net win in terms of CO2. Also, recycling steel releases less co2 than making it from scratch so there is a benefit after construction. Low energy efficient hydrogen will work if electricity is sufficiently cheap at purchase and hydrogen is sufficiently expensive at sale. Those factors will probably come to dominate more than conversion efficiency. Steel production just adds another potential customer to the mix.
