U.S. solar companies added a record-setting 32.4 gigawatts (GW) of new electric generating capacity in 2023, accounting for over half of new capacity additions to the grid in a first for the sector.
This is according to a solar market insight report released this week by the Solar Energy Industries Association (SEIA) and Wood Mackenzie. The growth, a 51% increase compared to 2022, is expected to continue as the nation turns to cleaner forms of energy to help lower greenhouse gas emissions, further incentivized by tax credits.
The report showed that every solar market segment—including residential, commercial, utility-scale and solar module manufacturing capacity—reported year-over-year growth to push total installed solar capacity in the U.S. to 177 GW. That number is expected to swell to 673 GW by 2034, providing enough electricity to power over 100 million homes, based on SEIA and Wood Mac estimates.
“A high case for U.S. solar with increased supply chain stability, more tax credit financing and lower interest rates would increase our outlook 17%,” said Michelle Davis, head of global solar at Wood Mackenzie and the report’s lead author. “A low case with supply chain constraints, less tax credit financing and static interest rates would decrease our outlook 24%. Various policy and economic outcomes will have big implications for the U.S. solar industry.”
Texas, the nation’s top producer of oil and wind energy, solidified its position as the leader for new solar installations at 6.5 GW. More than half of U.S. states now have at least 1 GW of total installed solar capacity, according to the report.

Toyota to Turn JV Firm with Panasonic into Wholly-owned Subsidiary
Toyota Motor Corp. and partner Panasonic Holdings Corp. agreed to make their joint venture (JV) firm, Primearth EV Energy Co., the automaker’s wholly-owned subsidiary, Toyota said on March 5.
The acquisition, which is expected in late March, will come as Toyota steps up mass production of batteries for hybrid electric vehicles (HEV). In addition to producing HEV batteries, Primearth will also start producing batteries for battery electric and plug-in hybrid EVs, Toyota said in its news release.
“More competitive batteries will enhance the appeal of Toyota’s electric vehicle offerings and contribute to achieving carbon neutrality through a multi-pathway approach,” the company said.
Aurora: UK, Italy Among Europe’s Hottest Battery Power Storage Markets
Britain, Ireland and Italy are the most attractive markets for investors in battery power storage, energy consultancy Aurora said March 6, citing the lucrative revenue models offered by their governments.
Spain, Germany and Greece are also showing promising signs, according to abstracts from Aurora Energy Research’s Market Attractiveness Report, which covered 24 European countries.
Aurora says it has enabled 1.5 billion euros ($1.6 billion) in battery investment and presented the report in a webinar.
“This market is literally exploding,” said Ryan Alexander, research lead of European power markets at Aurora, adding Europe was catching up with early movers such as Australia and the U.S. “It is moving from being a niche part in the energy system to actually one of the fundamental elements of it.”
Forecasting a seven-fold increase in European battery power storage capacity by 2030, Aurora said this translates into an investment opportunity of over 30 billion euros, rising to almost 80 billion euros by 2050.
Rising from 7.1 GW of installed grid-scale battery capacity in 2023, Aurora sees capacity increasing to 51 GW by 2030 and 98 GW by 2050. Italy alone is aiming for 9 GW by 2030.
Leading countries are offering secure revenue streams for the new capacity and wide wholesale price spreads, allowing battery operators to buy low and sell high. Britain, unlike mainland Europe, lacks strong inter-connectors with neighbors that could help cap prices.

Gold Hydrogen Begins Well Testing for Ramsay Hydrogen, Helium Project
Australia-based Gold Hydrogen has started exploration well testing focused on naturally-occurring hydrogen and helium in a non-petroleum system in South Australia.
The company on March 5 said its Ramsay 1 and Ramsey 2 wells drilled in late 2023 found natural hydrogen with up to 86% purity and helium at up to 6.8% of raw gas.
“The objectives of the exploration well tests are to obtain more samples of both natural hydrogen and helium for further specialist analysis in world-leading laboratories, and to extract both natural hydrogen and helium to surface,” the company said in a news release.
Preliminary technical results from testing are expected by April and will help inform future drilling and well completion designs, a future pilot program and longer-term commercialization planning, Gold Hydrogen said.
The company believes the area, which stretches across Yorke Peninsula and Kangaroo Island on petroleum exploration license 687, could hold an estimated 1.3 MMmt of natural hydrogen.

Hexicon JV Freja Explore Fish Farms at Offshore Wind Sites
Freja Offshore, a JV between Norwegian Mainstream Renewable Power and Swedish Hexicon AB, teamed up with Subfarm to examine how electricity production and fisheries can coexist.
As part of the collaboration, Freja plans to build a wind farm called Mareld offshore Sweden, where it wants to develop a sustainable fish farm.
“The region Västra Götaland needs to triple its electricity production in the coming years to meet the energy needs and offshore wind will play a key role. At the same time, wind power must be able to coexist with other important interests, not least the fishing industry and sea-based food production,” Hexicon said in a news release. “Therefore, Freja Offshore now wants to develop the possibility of running sustainable fish farms in connection with the Mareld wind farm.”
Working with Subfarm, a Norwegian sustainable fishery, plans are to place fish farms—anchored with their own systems—between wind turbine platforms. The fish boxes will be lowered to 50 m–70 m depth and hoisted up to the surface for checks and harvesting, the release states, and then taken by ship to land.
“The technology has been developed to cope with tough weather conditions in the North Sea and is based on methods previously used in the oil and gas industry for decades,” Hexicon said in a news release. “The entire system is controlled from a control station on land.”
Also participating in the project are the Lysekil Municipality, the research institute DHI and the Norwegian industrial cluster Blue Maritime Cluster, the release states.
