New Recycling Facility to Produce Critical Minerals for Batteries

Cirba Solutions affiliate Heritage Battery Recycling is planning to build a lithium-ion battery recycling facility in Eloy, Arizona, aiming to help close a critical mineral supply gap.

The facility will process lithium-ion end-of-life batteries and battery manufacturing scrap, and serve as a raw material feedstock to provide battery-grade salts for new cathode and battery manufacturing, such as nickel, cobalt, manganese and lithium, Cirba said in a news release Sept. 28.

“The lithium-ion battery market is expected to grow exponentially over the next several years, with a projected market size approaching $25 billion by 2028,” Cirba Solutions President and CEO David Klanecky said. “Federal incentives for the purchase of EVs (electric vehicles), requirements for domestic EV battery manufacturing included in the Inflation Reduction Act, and state requirements like California’s recent move to require all new vehicles sold in the state to be zero-emission by 2035, ensure that lithium-ion battery recycling will be critical for auto-manufacturers to meet demand and have a sustainable future.

Expected to begin operations in mid-2023, the facility will process enough battery material to support 50,000 EVs annually, the company said.

HENT’s role will include construction, technical installations and related infrastructure, according to a news release.

“With HENT now at the helm of constructing Giga Arctic, we expect to be well-positioned to meet our targets for clean battery production,” said Einar Kilde, executive vice president of project execution for FREYR. “We selected HENT as our partner on this journey due to their great track record in building and developing large and complex facilities, as well as their work with us so far on Giga Arctic.”

The two companies signed in December 2021 an initial collaboration agreement covering the first stage of development for the factory. The latest agreement kicks off the second phase, which includes construction of the plant.

Argentine State-run Miners Launch First-time Lithium Project

Units of Argentina’s state oil firm YPF will next month begin lithium exploration in a first-ever entry into the sector by state-run miners as the government aims to benefit from surging demand for the battery metal, according to a statement on Sept. 26.

Lithium prices have soared past $70,000 per tonne this year as the major automakers scramble to secure more supply of the ultra-light metal to shift production from fossil fuel-burning engines to electric-powered vehicles.

YPF lithium units, YPF Litio and Y-TEC, announced in a statement on Sept 26 the start of work on a 20,000-hectare area lithium prospecting project in Fiambala in western Catamarca province, a partnership with local mining firm Catamarca Minera y Energetica. The project seeks to identify the highest lithium concentrations in Fiambala salt flats.

The statement did not disclose how much they would invest in the project or the expected duration of the exploration phase.


HPCL-Mittal Energy to Start Up Bio-ethanol Plant in 2023

India’s HPCL-Mittal Energy Ltd. will start up a bio-ethanol plant at its Bathinda refinery in northern India in 2023 as part of measures to reduce its carbon emissions, a company official said Sept. 28.

“Our company is in the process of constructing 100,000 tonnes per annum ethanol plant based on agricultural inputs like waste food,” Pravin Shirke, assistant general manager at HPCL-Mittal Energy Ltd. (HMEL), said during a forum at the Asia Pacific Petroleum Conference.

The plant will be operational next year, he added.

HMEL is a joint venture between state-run Hindustan Petroleum Corp. Ltd. and Mittal Energy Investments.

India, the world’s third-biggest oil importer and consumer, has expanded the excise duty exemption for biofuels to encourage the blending of higher proportions of ethanol and components of vegetable oil with gasoline and diesel.

India plans to introduce 20% ethanol blending with gasoline in some parts of the country from April next year, followed by a nationwide rollout from 2025-26.


Chevron to Collaborate on Advanced Geothermal Technology Project in Japan

Chevron New Energies International signed a joint collaboration agreement on Sept. 25 with Japan’s Mitsui Oil Exploration Co. Ltd. (MOECO), according to a joint press release.

Through the agreement, the two companies will explore the technical and commercial feasibility of Japan’s advanced geothermal power capabilities through studying resource potential and evaluating the advanced closed loop (ACL) technology’s effectiveness for a future pilot program.

“Chevron and MOECO share a goal of delivering lower carbon energy solutions, while meeting the need for reliable, affordable energy,” Barbara Harrison, Chevron New Energies vice president of offsets and emerging, said in the release.

The companies could also assess the implementation of ACL-based advanced geothermal technology opportunities on a global scale.

ACL has the ability to enable access to geothermal resources at a wider range of temperatures and geologies with the use of alternative technology above and below the surface, differentiating it from conventional geothermal projects that use traditional steam turbines.

GEL Lands Funding for Penhallow Geothermal Project

U.K.-based Thrive Renewables said Sept. 29 it has provided initial funding for Geothermal Engineering Ltd.’s (GEL) planned geothermal production expansion in the U.K.’s Cornwall.

When complete, the two-well project is expected to deliver about 42,000 megawatt-hour (MWh) of baseload renewable electricity per year, enough to power around 11,000 UK homes, according to GEL.

The latest news comes after GEL secured planning permission for its second deep geothermal site at Penhallow, estimated to generate about 5 megawatt (MW) of baseload electricity and 20 MW of thermal heat to meet local demand, according to a news release.

The 4,500-m deep first well will bring naturally heated water to the surface, while the 3,000-m deep second well will be used to return the cooled fluid back underground after it has been used to produce electricity and heat, Thrive said in the release.

Plans are for construction to begin in 2023 with generation expected in 2026.

Thrive also provided funding for GEL’s United Downs geothermal project.

Transitional, ElectraTherm Form Partnership

Colorado-based geothermal company Transitional Energy and ElectraTherm have agreed to team up to convert waste heat to power in the oil and gas industry.

The letter of intent to partner announced Sept. 28 comes after the two worked together on a successful pilot project of Transitional’s Sedna Sled Geothermal System using ElectraTherm's Organic Rankine Cycle (ORC) equipment. The project took place earlier this year at an oil field in Nevada.

Transitional is using a proprietary system utilizing ElectraTherm’s equipment to generate power. The power come from thermal energy from operations at oil fields.

“We value collaboration at Transitional Energy and working more strategically with ElectraTherm will allow us to bring greater value to our customers,” Transitional Energy CEO Salina Derichsweiler said. “We believe integration of ideas will be the solution to energy insecurity and emission reductions.”

They aim to capture at least 95% of the CO₂ for permanent sequestration coupled with ammonia for efficient transportation and storage, the release stated.

Multiple regional energy centers in the U.S. will be evaluated.

“The magnitude of annual emissions reductions from our potential regional energy centers equates to eliminating the CO₂ emissions of over one-third of the total automobiles on the road in states as populous as Colorado, Arizona, and Massachusetts,” Tallgrass Segment President Dustin Bashford said in the release. “It is this type of meaningful decarbonization that we are committed to rapidly advancing.”


Shell Snaps Up African Solar Provider Daystar Power

Oil giant Shell will purchase African solar provider Daystar Power as it expands its global renewables portfolio, the companies said on Sept. 28.

Shell is one of the most influential oil producers in Africa, but the Daystar purchase is its first power acquisition on the continent, underscoring its mandate to cut its greenhouse-gas emissions in half by 2030.

“As we do this, we’re helping to address a critical energy gap for many who currently rely on diesel generators for backup power,” Thomas Brostrøm, Shell’s vice president for renewable generation, said in a statement.

Neither Shell nor Daystar commented on the sale price. Shell earmarked $2 billion-$3 billion in capital expenditure for renewables and energy solutions in 2022.

Daystar, headquartered in Lagos, provides off-grid power to commercial and industrial clients in Nigeria, Ghana, Togo and Senegal, offering solar and hybrid power solutions with battery storage. It has 300 power installations with installed solar capacity of 32 MW but aims to boost capacity to 400 MW by 2025.


Vattenfall Secures Rights to Build Major German Offshore Wind Farm

Swedish utility Vattenfall has obtained the rights to develop a large offshore wind farm project in the German part of the North Sea, which could start operations in 2027, it said Sept. 29.

Vattenfall had purchased the project previously known as “Global Tech II” in 2016, although a new offshore wind tendering system in Germany required it to confirm its intention to retain the rights, the company said.

“This is an important milestone for us in Germany as the government aims to increase generation of electricity from offshore wind to 30 gigawatt by 2030,” Catrin Jung, head of offshore wind at Vattenfall, said in a statement.

The wind farm off the coast of the North Sea island of Borkum would have a capacity of 980 MW, corresponding to the consumption of more than one million German households, the company said.

Vattenfall still has to make a final investment decision.

The Swedish energy firm already operates two offshore wind farms in the German part of the North Sea.
