# Low-Carbon Investments and Spending on Hydrogen and CCUS Expected To Surge as Inflation Weakens

## Spending on low-carbon projects will increase by $60 billion this year, 10% higher than 2022, led by wind developments but helped by a significant rise in funding for hydrogen and carbon capture, utilization and storage infrastructure, Rystad Energy research shows. Spending on low-carbon projects will increase by$60 billion this year, 10% higher than 2022, led by wind developments but helped by a significant rise in funding for hydrogen and carbon capture, utilization and storage (CCUS) infrastructure, Rystad Energy research shows. The growth in total spending is a slowdown from recent years—which averaged 20% annual increases—as cost-conscious developers tighten their purse strings after two years of soaring prices.

Investments in green sectors surged 21% in 2022 to overtake related oil and gas spending for the first time, but inflation-spooked developers seem set to rein in spending growth this year. However, as inflationary pressure weakens, Rystad expects spending to rebound.

Investments in the geothermal, CCUS, hydrogen, hydropower, offshore and onshore wind, nuclear, and solar industries are set to hit $620 billion in 2023, up from about$560 billion last year. Service segments included in Rystad's calculations include project equipment and materials, engineering and construction, wells, operations and maintenance, and logistics and vessels.

Solar and onshore wind will contribute the most by a sizable margin. Spending on solar investments will total $250 billion this year, rising only 6% over 2022. However, thanks to the falling cost of polysilicon, the primary cost driver of solar photovoltaic cells, capacity growth will be more substantial than dollar investments suggest. Despite a relatively insignificant rise in investment value, installed capacity is expected to swell by roughly 25% to 1,250 GW. Spending growth will vary widely across industries. Hydrogen and CCUS are expected to see the most significant annual increase, growing 149% and 136%, respectively. Total hydrogen spending will approach$7.8 billion in 2023, while CCUS investments will total about $7.4 billion. In contrast, the hydropower market is expected to shrink over 2022, while nuclear investments are forecast to stay relatively flat. Onshore wind investments are projected to increase by 12% to about$230 billion, while offshore wind spending is expected to jump 20% to \$48 billion. Expenditure in geothermal is expected to jump significantly—about 45%—albeit from a relatively low starting position.
