GDY report - an interesting litany for sure.
What worries me is the 'easy solution to the world's CO2' crowd think this is going to be cheap and achievable.
Bland assumptions - put cold water down , get the nice hot rocks to heat it up, take steam up other drill hole and, there you go, cheap clean energy.
Glossing over the physics (steam, temperature gradients), engineering (what are they going to drill with - ceramic pipes?), the chemistry (oh, you mean ground water isn't always pH neutral and host rocks inert? Hydrogen embrittlement, gases embedded in reservoir fluids ) and the economics (nice to have insurance; sure does blow out a non-income producing start-up's balance sheet), but all of that can be solved and, at vast taxpayer subsidy/ injection, Innamincka can then have endless power. Some time.
