Closing the $18 trillion gap to fund the green energy transition through to 2030 is being slowed by negative investment conditions according to a report from the consulting group BCG. Challenges include inflation, supply chain constraints and pressures, and higher costs of capital. However, the energy sector has responded proactively. Total energy sector transactions exceeding $320 billion so far in 2023 show that the industry is fine-tuning capital frameworks for the energy transition. The assessment comes from a publication released on 20 November by the Boston Consulting Group Centre for Energy Impact. Titled ‘Bridging the $18 Trillion Gap in Net Zero Capital’, the report is based on an analysis of 260 of the world's largest energy companies across power and utilities, oil and gas, and private equity.
The publication builds on the recent BCG Centre for Energy Impact report The Energy Transition Blueprint, which showed that an investment of $37 trillion is needed by 2030 to finance the energy transition. Of this, $19 trillion is already committed over the next seven years, with 20% forecast to come from government spending, and 80% from private capital. A broad mix of investors is expected to contribute to the latter, including a $2 trillion share from private equity, $3 trillion from the oil and gas industry, $4 trillion from national oil companies, and $6 trillion from utilities companies.
Committed investment includes nearly $2 trillion in new government spending, while company targets suggest a 15% increase in energy expenditures between 2023 and 2027, with an increasing share allocated to low-carbon investments. Approximately 70% of the capital flows expected through 2030 are forecast to originate in the US (30%), China (19%), and Europe (18%).
"The green energy transition requires a true partnership between the private sector, policymakers and regulators, and end users," said Rebecca Fitz, a BCG Centre for Energy Impact partner and associate director, and co-author of the report. "This critically important process will happen only if all stakeholders commit to overcoming the growing headwinds and finding strong incentives for green investments."
The most challenging areas
The vast majority of the $18 trillion shortfall, almost 90%, is traceable to two areas: electricity, including renewable power investments, and end use, such as consumer and industrial spending to bring down energy demand and emissions. The investment environment for renewables has been adversely impacted by the higher cost of capital, especially in the wind sector and, geographically, in North America. However, early signs point toward consolidation in renewables to support continued investment, and power and utility companies are divesting assets to reduce debt and meet financing requirements in the face of these challenges. For end users, a huge $9 trillion investment shortfall is expected through 2030. Challenges include bureaucratic hurdles, insufficient infrastructure, and weak business cases. In addition, most prospective investments, including 93% of proposed carbon capture projects, remain in the early planning stages.
"The energy sector accounts for almost a third of the world's annual capex, and its capital intensity rate is more than double that of others," said Maurice Berns, a BCG managing director and senior partner who chairs the Centre for Energy Impact and co-authored the report. "'The massive challenge we are seeing in green energy investment today is that upfront capex investment is much higher as a share of total energy production cost than in traditional hydrocarbons. The high cost of financing we are seeing now matters more than ever."
