Bioleaching: case studies and examples?
Bioleaching uses bacteria to metabolize insoluble sulfides and iron complexes. It produces 20% of the world’s copper; with 50% lower capex, at least 50% less CO2 and up to 80-90% recoveries; but it is currently limited to specific mineralogies. A prospect for the 2020s is that new technologies may unlock more minerals.

Methane slip: how much gas evades combustion?
Methane slip occurs when a small portion of natural gas fails to combust, and instead escapes into the atmosphere. This data-file reviews different technical papers. Methane slip is effectively nil at gas turbines and gas heating (less than 0.1%). It rises to 0.5-3% in cookstoves and some dual-fuel marine engines. However, the highest rate of…

Solar surface: silver thrifting?
Ramping new energies is creating bottlenecks in materials. But how much can material use be thrifted away? This is a case study of silver intensity in the solar industry, which halved in the past decade, and could halve again. Conclusions matter for solar companies, silver markets, other bottlenecks.

Liquefied CO2 carriers: CO2 shipping costs?
This model captures the economics of a CO2 carrier, i.e., a large marine vessel, carrying liquefied CO2, at -50ºC temperature and 6-10 bar pressure, for CCS. A good rule of thumb is seaborne CO2 shipping costs are $8/ton/1,000-miles. Shipping rates of $100k/day yield a 10% IRR on a c$150M tanker.

Energy transition: the very hungry caterpillar?
The universe of energy transition stocks seems small at first. 50 clean tech companies have $1trn in combined value, less than 1% of all global equities. But decarbonizing the world is insatiable. Consuming ever more sectors. We are now following over $15trn of market cap across new energies, (clean) conventional energy, utilities, capital goods, mining,…

Tree seedlings: costs and economics?
The US plants over 1.3bn tree seedlings per year. Especially pine. These seedlings are typically 8-10 months old, with heights of 25-30mm, root collars of 5mm, and total mass of 5-10 grams, having been grown by dedicated producers. This data-file captures the costs of tree seedlings, to support afforestation, reforestation or broader forestry.

Verbio: bio-energy technology review?
Verbio is a bio-energy company, founded in 2006, listed in Germany, producing bio-diesel, bioethanol, biogas, glycerin and fertilizers. The company has stated “we want to be in a position to convert anything that agriculture can deliver to energy”. Our Verbio technology review is based on its patents. We find some fascinating innovations in cold mash…

CO2 compression: stranger things?
CO2 is a strange gas. This matters as energy transition will require over 120 GW of compressors for 6GTpa of CCUS. This 13-page notes explains CO2’s strange properties, which helps to fine-tune appropriate risking factors for vanilla CCS, blue hydrogen, CO2-EOR, CO2 shipping, super-critical CO2 power cycles. There is also a wide moat around leading…

Renewables: how much time to connect to the grid?
Is the power grid becoming a bottleneck for the continued acceleration of renewables? The median approval time to tie a new US power project into the grid has climbed by 30-days/year since 2001, and doubled since 2015, to over 1,000 days (almost 3-years) in 2021. Wind and solar projects are now taking longest. This data-file…
