Highview to pair solar with cryogenic energy storage in Chile’s Atacama

Highview Enlasa, the 50/50 joint venture between Highview Power and Energía Latina SA-Enlasa, has announced the development of the first liquid air long duration energy storage project in Chile.

This 50 MW/500 MWh (10 hours) CRYOBattery™, which represents an estimated investment of $150 million, will be in Diego de Almagro in the Atacama Region.

With one of the highest solar irradiations in the world, the Atacama Region has the potential to generate all the country’s electricity. By pairing solar with cryogenic energy storage, Chile can benefit from 24/7, 100% renewable energy, according to Highview Power.

Engineering, procurement, and construction (EPC) on the project will be carried out by SK Ingeniería y Construcción, a leading Chile-based EPC contractor and a subsidiary of the Sigdo Koppers group. The project is currently in the pre-feasibility engineering phase and is scheduled to enter environmental permitting in August. Construction is estimated to start in the second half of 2023.

Javier Cavada, CEO and President of Highview Power, said: “This is a big step forward to enabling decarbonisation goals for the country of Chile. Our liquid air energy storage technology is the optimal solution for the large scale, long duration energy storage that is needed to balance the grid, without the geographic constraints associated with other energy storage technologies.”

The Highview Enlasa joint venture is opening Latin American energy markets to baseload renewable energy potential, the companies say. When paired with renewable energy sources such as solar, Highview Power’s long duration energy storage system is equivalent in performance to thermal and nuclear power, it claims. CRYOBatteries are developed using proven components from mature industries and can deliver pumped-hydro capabilities without geographical constraints.

Fernando del Sol, President of Highview Enlasa, added: “The objective of our company is to make this innovative technology available to the market and to all actors in the electrical and mining sectors. These plants can replace traditional coal plants, which will help us contribute to accelerating the decarbonisation process in Chile and to combat climate change.”

Highview Power’s proprietary cryogenic energy storage technology uses air liquefaction, in which ambient air is cooled and turned to liquid at -196°C. The liquid air is stored at low pressure and later heated and expanded to drive a turbine and generate power. It is the only long duration energy storage solution available today that is locatable and can offer multiple gigawatt-hours (weeks) of storage, according to the company.

“The CRYOBattery has a small footprint and is scalable with no size limitations or geographic constraints, allowing for the deployment of massive amounts of renewables,” the company said.

Highview Power’s cryogenic energy storage plants offer valuable capabilities including voltage control, grid balancing and synchronous inertia that give grid operators the flexibility to manage power and energy services independently.”

Capstone Mining eyes Santo Domingo IOCG project capex cuts with PASA MoU

Capstone Mining’s 70%-owned subsidiary Minera Santo Domingo (MSD) has entered into an agreement that could see it slash some $400 million off the capital cost for building its Santo Domingo copper-iron-gold project, in Chile’s Region III, by offloading the port and concentrate transport infrastructure development to another company.

The Memorandum of Understanding (MoU) with Puerto Abierto SA (PASA), a wholly owned subsidiary of Puerto Ventanas SA (also a subsidiary of Sigdo Koppers SA) will see both MSD and PASA, over a 90-day period, explore mutual synergies and regional benefits for the proposed port component of the Santo Domingo project, Puerto Santo Domingo.

The port, which is fully permitted and located 100 km from the Santo Domingo project site, will be one of only two capesize vessel ports in the region, making it an attractive site for bulk shipments and a key asset allowing for broad resource development in Region III, Capstone says.

Santo Domingo is owned 70% by Capstone and 30% by Korea Resources Corp. A February 2020 technical report outlined an 18-year operation with a life of mine average throughput of 60,500 t/d for annual output of 137 Mlb (62,142 t) of copper, 4.2 Mt of iron ore and 17,000 oz of gold at the project. Development capital for this study came in at $1.51 billion (excluding cobalt processing).

As part of the MoU, MSD will allow PASA to study, at its own cost, the project engineering and conduct a market study over the 90-day period.

PASA is looking to potentially acquire, construct, operate and maintain the deep-water port, including financing its development, Capstone said. Once in operation, Santo Domingo will receive preferred service as its volumes will represent  a baseload of business for the port.

The MOU also gives PASA 90 days to evaluate the replacement of the 110 km magnetite concentrate pipeline with a railway as part of its rail business, Ferrocarril del Pacifico SA.

The project infrastructure under consideration in this MoU represents some $400 million of the capital expenditure identified in the most recent technical report, Capstone says, and includes:

  • Marine works including pier;
  • Iron concentrate pipeline from Santo Domingo mine to port;
  • Magnetite filter plant and stockpile building;
  • Copper storage building; and
  • Ship loading and support facilities.

“Over the past three months we have seen a surge in interest in our fully permitted Santo Domingo project,” Darren Pylot, President and CEO of Capstone, said. “I believe this relationship with Puerto Ventanas will serve as a major catalyst for our Santo Domingo project. Our path forward includes successful culmination of the strategic sales process, executing a gold stream agreement and arranging project debt financing.”

Dr Albert Garcia, VP, Projects at Capstone, said the partnership with PASA, coupled with the fixed cost, turnkey proposal from POSCO E&C, significantly “de-risks” the overall project.

ENAEX and Sasol sign explosives and rock fragmentation JV to service southern Africa

ENAEX, a subsidiary of the Sigdo Koppers Group, says it has reached an agreement with integrated energy and chemical company, Sasol, to become a strategic partner of its explosives and rock fragmentation division.

The agreement, signed this week after a negotiation process initiated last July, considers ENAEX to take part in the business as the controlling partner of this firm, it said. This would be formed by spinning off certain assets and associated activities within the current explosives value chain of the Base Chemicals business of Sasol South Africa.

The new joint venture company will include the associated business activities in both South Africa and the rest of the countries in Southern Africa, with the explosives division having over 1,000 employees, producing more than 350,000 t/y of explosives and generating around $250 million of revenue annually, ENAEX says.

Sasol was founded in 1950 and is today a participant in the explosives industry in South Africa, with a presence also in Namibia and Lesotho.

Juan Andrés Errázuriz, ENAEX CEO, said: “Having successfully completed the process to become a strategic partner of Sasol is a very relevant milestone for Enaex. By this, we have taken a big step in consolidating our company in international markets and expanding the value offer for our customers.”

Errázuriz said, because of its size, Africa was currently the third largest explosive market in the world, with significant growth potential.

“Towards its progress, we can contribute with the extensive knowledge, technology and innovation that we have been developing in the rock fragmentation industry for mining,” he said.

This joint venture is part of the strategic plan of ENAEX to continue strengthening its international presence in the most important mining regions of the world and is subject to any necessary approvals from public authorities, it said.
