Insulation materials: leading companies?
This data-file profiles a dozen companies that make thermal insulation materials, as 50-75% of all buildings standing today will likely need insulation upgrades on the road to ‘net zero’, while the pace of progress should be amplified in times of energy shortages.

Insulation: deliver us from gas shortages?
Insulating materials slow the flow of heat from a warm house by 30-100x. But 60-90% of today’s housing stock is 30-70% under-insulated. We think renovation rates could treble as gas shortages re-prioritize energy savings. This 12-page note screens who might benefit.

Aspen Aerogels: insulation breakthrough?
Aerogels have thermal conductivities that are 50-80% below conventional insulators. Target markets include preventing thermal runaway in electric vehicle batteries and cryogenic industrial processes (e.g., LNG). This data-file notes some challenges, using our usual patent review framework.

Construction materials: a screen of costs and CO2 intensities?
This data-file calculates the costs, the embedded energy and the embedded CO2 of different construction materials, both during their production and for ongoing heating and cooling. Insulated wood and cross-laminated timber have the lowest CO2 intensities and can be extremely cost competitive.

Air conditioning: energy consumption?
The average US home uses 2,000 kWh of electricity for air conditioners each year. Air conditioning energy consumption is broken down from first principles in this data-file, as a function of temperatures, humidity, heating days, household size, insulation and coefficient of performance (COP). What routes to lower the air conditioning energy demand and CO2 emissions?

Polyurethane: leading companies?
This data-file is a screen of leading companies in polyurethane production, capturing 80% of the world’s 25MTpa market, across 20 listed companies and 3 private companies. We see growing demand for polyurethanes — especially for insulation, electric vehicles and consumer products — while there is also an exciting prospect that EVs displace reformates from the…

NEL: green hydrogen technology review?
NEL is a green hydrogen technology company, headquartered in Oslo, listed on the Oslo Børs since 2014, and employing 575 people. It has manufactured 3,500 electrolyser units, going back to 1927, historically weighted to alkaline electrolysers, and increasingly focused on PEMs and hydrogen fuelling stations. This NEL technology review explores its patents.

Poly Vinyl Chloride: the economics?
This data-file estimates the cost of PVC production and the cost of VCM production, from first principles, based on capex, input materials, heat, electricity, labor and other opex. As a rule of thumb, 10% IRRs require c$900/ton PVC and c$750/ton VCM, and PVC will embed around 2 tons of CO2 per ton of PVC. Numbers…

Bill of materials: electronic devices and data-centers?
Electronic devices are changing the world, from portable electronics to AI data centers. Hence what materials are used in electronic devices, as percentage of mass, and in kg/kW terms? This data-file tabualates the bill of materials, for different devices, across different studies.

Thermal energy storage: cost model?
This data-file captures the costs of thermal energy storage, buying renewable electricity, heating up a storage media, then releasing the heat for industrial, commercial or residential use. Our base case requires 13.5 c/kWh-th for a 10% IRR, however 5-10 c/kWh-th heat could be achieved with lower capex costs.
