Proposal: Hydrogen powered furnace for use melting metal without generating pollution

Contest: Industry

Thank you for your contest entry. We appreciate your willingness to share your ideas and also the time and effort you put into developing a proposal and submitting it to the contest.

We, the Judges, have strongly considered your proposal and found that it contained intriguing elements; however, we have chosen to not advance it to the next round of competition.

We encourage you to keep developing your idea. Transfer your proposal to the Proposal Workspace to re-open it, make edits, add collaborators, and even submit it into a future contest. You can do so by logging into your account, opening your proposal, selecting the Admin tab, and clicking “Move proposal”.

We welcome you to stay involved in the Climate CoLab community: support and comment on proposals that have been named Semi-Finalists and finalists, and even volunteer to join one those teams if you have relevant expertise. During the voting period, you can help select the contest’s Popular Choice Winner. The Climate CoLab will be opening more contests in the coming months, and you are welcome to submit your proposals to those contests as well.

Keep up the great work. We hope that by working together, we all can create solutions that wouldn’t otherwise be possible.

Definitely new foundry technologies would be helpful. This idea needs further development.

This proposal would be strengthen by at least including a description of the hydrogen supply (and the embodied energy and emissions of the H2).

The use of H2 as a fuel resource is not new and significant amounts of R&D have been spent on this topic over the last few decades. And yet it is still hard to see a cost-effective and low-carbon pathway for generating and supplying H2. If this problem is overcome, then industry would certainly adopt a "clean fuel" that would lower their emissions. So we see the issue being more about H2 supply, than the technologies for using H2 (such as this proposal).

We are giving this proposal a lower "impact" rating because of the limited steel raw capacity remaining in the U.S. China, for example, has an order of magnitude greater steel production capacity. And we are sure that China would also use low-cost/low-carbon intensive H2 if it was available.

To get clean Hydrogen fuel you still need to consume tremendous amount of energy. 61% of steel today is melted from scrap using electricity. The steel produced using electric arc furnaces is called secondary steel. Primary steel is produced using blast furnaces. Coke is needed in blast furnace operation. Energy intensity of EAFs (MMBtu/metric tons of steel produced) is much less compared blast furnaces.

The concept seems innovative but it's not clearly presented.
