The tech developments come as Honda gears up to produce a new hydrogen fuel cell electric vehicle (FCEV) based on its Honda CR-V in the U.S.

Here’s a look at some of this week’s renewable energy news.


Battery Maker SK On, Hyundai Seals EV Battery Pact

South Korea’s SK On has signed an agreement with Hyundai Motor Group to supply electric vehicle (EV) batteries to factories in North America, the battery manufacturer said Nov. 28.

As part of the agreement, SK On will provide its batteries to Hyundai’s EV plants in the U.S. after 2025 as the automaker works to produce various EV models, the company said in a news release.

“We expect the cooperation between SK On and Hyundai Motor Group to create a big synergy,” SK On Chief Administrative Officer Choi said. “With the latest MOU (memorandum of understanding), both sides can hold a solid position in the process of electrification in the North American auto market.”

To meet requirements of the Inflation Reduction Act in securing lithium, SK On said it recently signed purchase contracts with resource development companies in countries that have signed Free Trade Agreements with the U.S. These, according to the news release, include Australia and Chile.

SK On currently has an EV battery factory in Georgia. The company’s batteries are used on Hyundai’s Hyundai IONIQ 5, IONIQ 6, and Kia EV6.

Natron Energy Lands Investment from United Airlines

Battery manufacturer Natron Energy has secured an investment from United Airlines as it aims to electrify its airport ground equipment such as pushback tractors and gate operations. The strategic equity investment was announced Nov. 30.

“Natron’s cutting-edge sodium-ion batteries presented an ideal opportunity to both potentially expand our sustainability investment portfolio to our ground operations, and to help make our airport operations more resilient,” said Michael Leskinen, president of United Airline Ventures.

About a third of the United’s more than 12,000 pieces of motorized equipment is electric, Natron said, noting its batteries could be used for charging.

“Our batteries provide the high power over short distances that ground service equipment needs,” said Natron Energy CEO Colin Wessells, “and unlike lithium-ion, Natron’s batteries are completely nonflammable and can be safely deployed into ground service operations.”

The company said it plans to use the funds to accelerate production at its Holland, Michigan, manufacturing facility. Mass production at the facility is expected to start in 2023.

Renault-Airbus Partnership to Develop New Generation of Electric Batteries

Startup Battolyser Systems Eyes Its First Large-scale Factory

Battolyser Systems, the Dutch manufacturer of an integrated battery and electrolyzer hybrid system, plans to build its first large-scale factory in The Netherlands to help meet demand for green hydrogen and electric storage, the company said Nov. 28.

Located at the port of Rotterdam, the 1-GW per annum Battolyser factory will span 14,000 sq m and cost about €100 million (US$104.6 million) to build, the company said in a news release. The facility would also be home to Systems’ headquarters and R&D center.

“This partnership with port of Rotterdam to develop our first large scale manufacturing facility together is a big step forward in our commercialization,” said Battolyser Systems CEO Mattijs Slee. “The factory allows us to deliver Battolysers at industrial scale and affordable prices. We are in constructive conversation with the Dutch government and EU institutions, and we are confident that together we can secure the required funding.”

A final investment decision on the facility is anticipated by late 2023. If given the green light, the facility would open during second-half 2024.

Called a world first, Battolyser’s integrated battery and electrolyzer system—called the Battolyser—can produce hydrogen from solar and wind when power prices are low and provide electricity to the grid when prices are high, the company said.

“A net zero world will require between 5,000 and 10,000 GW of installed electrolyzer capacity,” Slee said. “The electrolyzer supply chain is a huge opportunity for The Netherlands to develop new sustainable industries that can support our energy transition needs and offer export products to world.”
