Fuel cells: performance, efficiency and decline rates?
This data-file captures the performance of c160 fuel cell power plants, installed to-date in the US, generating over 2TWH of electricity, looking facility-by-facility, year-by-year. How has the performance, efficiency and longevity of US fuel cell power plants been trending over time?

Floating offshore wind: what challenges?
A dozen challenges for floating offshore wind projects are ranked in this 4-page note, by reviewing 50 recent patents across the industry. We model these challenges are likely to double capex and levelized costs, compared with traditional offshore wind. The potential for floating offshore wind is also location dependent.

Solid oxide fuel cells: what challenges?
This data-file reviews fifty patents into solid oxide fuel cells, filed by leading companies in 2020. The key focus areas are improving the longevity and efficiency of SOFCs. But unfortunately, we find many of the proposed solutions are likely to increase end costs. Potential is interesting, but deflation may take longer.

Nickel, manganese, cobalt: sufficient reserves for the rise of EVs?
This data-file models whether there will be enough nickel, manganese and cobalt, to build the batteries behind the vast rise of electric vehicles embedded in our oil demand forecasts. Strong reserve replacement makes nickel and manganese unconcerning. But cobalt may be a challenge.

CO2 electrolysis: the economics?
Carbon monoxide is an important chemical input for metals, materials and fuels. Could it be produced by capturing CO2 from the atmosphere or using the amine process, then electrolysing the CO2 into CO and oxygen? We find 10% IRRs could be achievable at $800/ton, competitive with conventional syngas.

CO2-EOR: the economics?
This data-file is captures the costs of CO2-enhanced oil recovery, which can lower the total CO2 intensity across the oil industry by 50-100%, while economically storing CO2. We calculate 10% IRRs are attainable under our base case assumptions at $50/bbl oil prices and $20/ton CO2 prices. The work includes a full cost breakdown.

Metal organic frameworks: challenges and opportunities?
Metal organic frameworks (MOFs) are an exciting class of materials, which could reduce the energy penalties of CO2-separation by c80%, and reduce the cost of carbon capture to $20-40. This data-file screens companies developing metal organic frameworks, where activity has been accelerating rapidly, especially for CCS applications.

Hydro electric power: the economics?
A typical hydro project requires a 10c/kWh power price and a $50/ton CO2 price to generate an unlevered IRR of 10%. 80% of the cost is capex. Hence at a 6% hurdle rate, the incentive price falls to 6c/kWh. Cash opex is 2c/kWh. CO2 intensity is effectively nil, even after reflecting the construction energy.

Wind and solar capacity additions?
Global wind and solar capacity additions reached 600GW pa (AC-basis) in 2024, which is 2x higher than in 2021 and 10x higher than in 2011. The pace of gross wind and solar capacity additions can rise by a further 5x by 2050, bringing wind and solar to 60% of a greatly expanded global power grid…

Cryogenic air separation: costs and energy economics?
This data-file calculates the costs of cryogenic air separation units, which are important in the production of industrial gases, ammonia, metals, materials, medical applications and new energy technologies such as blue hydrogen. Good base cases are $100/ton oxygen, $20/ton nitrogen, $200/Tpa capex and 60kWh/ton of electricity (on an input air basis).
