Selected asset investments

MR Vessels

Hartree is building a portfolio of medium range product tankers. These vessels, which will be among the most fuel efficient MRs in operation, are designed with technology that allows the burning of methanol as fuel, in order to best comply with future environmental regulation. These vessels provide transportation of both hydrocarbon and non-hydrocarbon cargoes such as vegetable oil or biofuels.

Channelview Splitter

In 2020, Hartree purchased a condensate splitter located in the Houston Ship Channel. The facility includes storage, truck and dock infrastructure, as well as the ability to process up to 50,000 barrels per day of crude oil and condensate into marketable and intermediate products.

Cushing Storage

In 2020, Hartree acquired 3 million barrels of crude oil storage in Cushing, Oklahoma. This storage facility is located within the world’s largest crude oil storage complex, with significant pipeline interconnectivity, allowing for the ability to source and deliver crude oil throughout the US.

UK Power Peaking Assets

Since 2016, Hartree built and operates small-scale power generation in the UK. These assets are strategically located to capitalize on locational mismatches between supply and demand in the regional UK power markets and fill the void created by the growth of renewable power.


In 2021, Hartree acquired a controlling interest in Sprague Resources LP (NYSE: SRLP). Founded in 1870, Sprague is one of the largest independent suppliers of energy products and related services in the Northeast US, where its strategically located refined products and materials handling terminals are located. Their location and natural gas pipeline capacity provides Sprague with access to energy products and services to supply their 20,000 retail, commercial, industrial, utility and wholesale customers. Sprague continues to transition its business to provide clean fuels to Northeast markets. In addition to assisting its customers, Sprague has developed a program to install flexible, thin-film solar panels on its bulk storage tanks to reduce its own carbon footprint and energy costs.
