Key Takeaways
- • Blackstone's energy transition fund raised $8.7 billion from investors in 2026 year-to-date, according to the company's mid-October announcement, and turned away an additional $3 billion to stay under its maximum investment cap.
- • Private equity 'transition' funds raised $178 billion between 2021 and the beginning of 2026, triple the amount raised by comparable fossil fuel and general energy funds, according to BloombergNEF analyst Ryan Loughead's research.
- • Blackstone's fund, which stopped investing in oil and gas production in 2017, still invests in natural gas plants and data center-related companies, with fund director David Foley arguing renewables alone cannot replace existing coal and gas power.
- • Three government-managed investors with explicit climate goals, the Oregon Treasury, Minnesota State Board of Investment, and San Francisco Employees' Retirement System, have committed a combined $525 million to the fund, per Private Equity International.
- • Climate and environmental groups strongly reject gas as a transition fuel, and Cohn of IEEFA argues the case for gas is 'increasingly contested' as solar, wind, and batteries mature.
Summary
Blackstone is one of several energy transition funds at private equity firms that have grown steadily over the past decade, even as general climate-oriented investment has declined in recent years. According to research by Ryan Loughead, a former climate solutions analyst for BloombergNEF, transition funds raised $178 billion between 2021 and the beginning of 2026, triple the amount raised by comparable fossil fuel and general energy funds. On Wall Street, the term can differ from its everyday meaning of a shift away from fossil fuels. Blackstone's fund sees profit opportunities in natural gas, data centers, and rising electricity costs. Loughead said many investors consider gas a transition fuel, and that funds including gas have tended to show slightly higher returns.
Fund director David Foley defended continued investment in gas plants, arguing that adding renewables does not by itself allow existing coal and gas capacity to be retired. This year the fund announced investments in six companies, including a natural gas plant operator, a data center cooling technology company, a renewable energy developer, and transmission and grid technology firms. Blackstone did not respond to a request for comment. Dan Cohn of the Institute for Energy Economics and Financial Analysis said investors are anticipating electricity scarcity driven by data center demand, and that the energy transition has matured into an established investment sector.
Other managers take different approaches. Brookfield says it will invest in gas only where it replaces dirtier fossil fuels, though it has faced criticism for describing gas expansion as part of the transition. Copenhagen Infrastructure Partners' Energy Transition Fund focuses on clean sources such as green hydrogen. BlackRock distinguishes 'transition' from 'sustainable' investing, stating that not all transition strategies are sustainable. Oregon, Minnesota, and San Francisco, which collectively committed $525 million to Blackstone's fund, have climate goals that may sit uneasily with gas exposure. An Oregon state representative has asked the treasury to more clearly define its 'climate-positive' category. None of these investors responded to requests for comment.
Climate groups counter that gas still generates significant emissions through combustion and leakage, and that data centers are increasing fossil fuel use. The Natural Resources Defense Council's Shruti Shukla wrote in a 2025 article that gas 'no longer functions as a credible bridge in the energy transition.' Cohn suggested that falling costs for solar, wind, and batteries may eventually make fossil fuel investments less attractive on Wall Street.
