Image:The Ring of Fire awakens: Rugged terrain at Gunung Hamiding, North Maluku, where exploration wrapped up confirming up to 60 MW of untapped geothermal might

Welcome back to Alphaxioms Geothermal News, your go-to source for the latest in renewable energy innovations from around the globe. As we dive into 2026, the world is buzzing with the urgent need for sustainable power sources, and Indonesia is leading the charge with its vast geothermal treasures. Today, we're spotlighting a game-changing development from PT Barito Renewables Energy Tbk (BREN) that's not just about megawatts—it's about reshaping our planet's energy future. Imagine tapping into the raw power simmering beneath volcanic peaks, turning steam into electricity that powers homes, industries, and dreams. That's exactly what's unfolding at Gunung Hamiding in North Halmahera, where Star Energy has just wrapped up an exploration phase revealing a whopping 55-60 MW of geothermal potential. Buckle up as we unpack this electrifying story in detail.

The Dawn of a New Era in Halmahera

Picture this: a remote, rugged landscape in Indonesia's eastern archipelago, where ancient volcanoes hold secrets of untapped energy. PT Star Energy Geothermal Indonesia, a key subsidiary of BREN, has been on a mission here since receiving the green light from the government back in 2013 via Ministerial Decree No. 0459K/30/MEM/2013. Their target? Gunung Hamiding, a geothermal prospect in North Halmahera Regency that's now confirmed to pack a punch of up to 60 MW—enough to light up thousands of households and fuel local economies.

The exploration wrapped up on January 14, 2026, marking a pivotal milestone in BREN's phased approach to development. This isn't some hasty dig; it's a meticulous process aligned with the Ministry of Energy and Mineral Resources (ESDM) guidelines. Teams conducted comprehensive surveys,geological, geochemical, geophysical, and geotechnical,followed by civil engineering feats and exploratory drilling. It's like piecing together a giant underground puzzle, where every data point reveals more about the hot reservoirs lurking below.

Hendra Soetjipto Tan, President Director of Barito Renewables, couldn't hide his enthusiasm. In a statement released on January 13, he called it a "significant milestone" in their stepwise journey toward an initial 50 MW geothermal power plant in Halmahera. "This achievement reflects our commitment to providing clean, reliable energy while supporting Indonesia's transition to a sustainable energy future," Tan said. His words echo the broader vision: turning volcanic heat into a lifeline for a nation hungry for green power.

But let's get into the nuts and bolts. To make this happen, Star Energy didn't just poke around—they built an infrastructure backbone. They extended existing access roads by 7.7 kilometers, carved out 13.8 kilometers of brand-new paths through challenging terrain, constructed three sturdy bridges, and set up a dedicated well pad. These aren't mere conveniences; they're essential for safe, efficient operations in a region where Mother Nature doesn't always play nice. Imagine crews navigating misty mountains, drilling into the earth while ensuring minimal disruption to the ecosystem. It's engineering heroism at its finest.

Beyond Power: Environmental and Social Ripples

Geothermal energy isn't just about flipping switches,it's a holistic revolution. At Hamiding, the project promises to slash reliance on fossil fuels, curbing greenhouse gas emissions that choke our atmosphere. In a world grappling with climate chaos, this is a breath of fresh air (literally). Indonesia, with its Ring of Fire location, sits on a goldmine of geothermal resources, and developments like this are key to unlocking it without the carbon footprint of coal or oil.

On the social front, Star Energy is walking the talk. They're collaborating with local communities and stakeholders in North Halmahera to create jobs, upgrade infrastructure, and roll out social programs. Think about it: new roads mean better access to markets and healthcare; employment opportunities empower families; and community initiatives foster long-term harmony. This isn't corporate lip service—it's real impact. As Tan's team pushes forward, they're ensuring that the benefits flow beyond the power grid, nurturing a symbiotic relationship between industry and locals.

Zooming out, this fits into Indonesia's grand geothermal narrative. According to ESDM data, the country's installed geothermal capacity stands at 2,744 MW, making it the world's second-largest after the United States' 3,937 MW. Yet, that's just scratching the surface—only about 10% of the nation's immense potential has been tapped. Minister Bahlil Lahadalia recently highlighted this disparity: "Geothermal is one of our renewable energy sources, and Indonesia has the largest reserves in the world. But we've only managed around 10% so far, meaning 90% is still out there." His words are a rallying cry for acceleration.

Indonesia's Geothermal Giant Awakens

Indonesia's geothermal story is one of epic proportions. Straddling tectonic plates, the archipelago boasts over 400 volcanoes, many harboring geothermal hotspots. With reserves estimated at a staggering 24,000 MW or more, it's no wonder experts call it the "sleeping giant" of renewables. But awakening this giant requires vision, investment, and policy muscle.

Enter the government's Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) for 2025-2034, a blueprint that's supercharging the sector. Plans include building 48,000 kilometers of transmission lines to connect remote geothermal sites like Hamiding to the national grid. This infrastructure push isn't just wires and poles,it's the veins that will pump clean energy across islands, from Sumatra to Papua. By integrating renewables, Indonesia aims to hit its net-zero emissions targets while bolstering energy security amid global volatility.

Compare this to global peers: The U.S. leads, but Indonesia's potential dwarfs it. Countries like Iceland and New Zealand have long harnessed geothermal for heating and power, proving its reliability,it's baseload energy, running 24/7 unlike intermittent solar or wind. For Indonesia, scaling up could mean energy independence, reduced imports, and a starring role in the global green transition. Projects like Hamiding are the building blocks, demonstrating that with the right expertise (shoutout to Star Energy's track record), barriers like remote locations and high upfront costs can be overcome.

Challenges remain, of course. Geothermal development demands hefty initial investments for exploration and drilling, and regulatory hurdles can slow progress. Environmental concerns, such as land use and water impacts, must be managed meticulously. But successes like this one show the path forward: transparent, community-driven, and tech-savvy approaches that minimize risks and maximize gains.

Looking Ahead: A Steamy Future

As we wrap up this deep dive, it's clear that Star Energy's Hamiding breakthrough is more than a corporate win,it's a beacon for sustainable development. With 55-60 MW on the horizon and plans for a 50 MW plant, BREN is positioning Indonesia as a geothermal powerhouse. This aligns perfectly with national goals, where Minister Lahadalia's 90% untapped potential beckons like buried treasure.

For investors and eco-enthusiasts alike, keep an eye on BREN. Their commitment to clean energy isn't just talk; it's action, from Halmahera's hills to the boardrooms of Jakarta. As global demands for renewables soar—think electric vehicles, data centers, and climate accords,Indonesia's geothermal surge could power a brighter tomorrow.

Ijen vs Zanskar: Blind Geothermal Energy Discovery and Development

Ijen’s Blind Geothermal System vs. Zanskar’s AI-Discovered Resources: Two Models for Finding Hidden Heat The geothermal industry is entering a new phase in which the most valuable resources may no longer be the fields marked by obvious hot springs, geysers, fumaroles, or steaming ground. Increasingly, developers are targeting “blind” or hidden geothermal systems,reservoirs that lack clear surface expressions but can still contain the temperature, permeability, and fluid needed for commercial power generation. Two examples illustrate how different parts of the industry are approaching this challenge. In Indonesia, the Blawan-Ijen geothermal field in East Java was developed through geological interpretation, magnetotelluric imaging, conceptual modelling, and drilling. The project is now operating commercially, with its first phase delivering approximately 35 MW to the Java grid under a 30-year power purchase agreement.  In the United States, Zanskar Geothermal & Minerals is using...

Vercana Electric Rig Advances Geothermal Brine Lithium Extraction Economics

Electric-Rig Direct Lithium Extraction From Geothermal Brine: The Economics of Vercana Versus Ormat Vulcan Energy Resources is pursuing an integrated model that combines geothermal drilling, direct lithium extraction, renewable electricity and industrial heat. Through its Vercana subsidiary, the company is also using electric drilling equipment designed to support the development of its Lionheart project in Germany’s Upper Rhine Valley. The approach differs from the conventional geothermal model represented by Ormat Technologies, whose core business remains geothermal power generation, equipment, project development and energy storage rather than commercial lithium recovery from geothermal brine.  The economic question is broader than whether an electric drilling rig costs less to operate than a diesel rig. The more important issue is whether electric drilling, geothermal energy and direct lithium extraction can create a more valuable integrated project than a conventional geotherm...

California Court Orders New Environmental Review for Imperial County Geothermal Lithium Project

California Appeals Court Orders New Environmental Review for Imperial County Geothermal–Lithium Project Image: California Salton Lake Sea Hell’s Kitchen geothermal and lithium extraction plan sent back for deeper water, air-quality and mitigation analysis under CEQA A California appeals court has ordered Imperial County to conduct a more rigorous environmental review of the proposed Hell’s Kitchen geothermal power plant and lithium extraction project near the Salton Sea. The Fourth District Court of Appeal found that the county’s original environmental impact report (EIR) did not adequately address long-term water availability, enforceable mitigation measures for water shortages, or potential air-quality impacts tied to the receding Salton Sea. The ruling partially reverses a lower court decision and remands the case to Imperial County Superior Court, requiring the county and project developer Controlled Thermal Resources to address the identified deficiencies before the project can m...

Maryland Geothermal Rebate Program 2026: Residential Heating and Cooling Incentives Drive Strong Demand

Maryland’s Geothermal Rebate Program  FY26 Geothermal Rebate Program is entering its final stretch with funding already oversubscribed, which is a strong sign that homeowner interest in geothermal heating and cooling is rising quickly in the state.  The program offers a $3,000 rebate for eligible new geothermal heating and cooling systems for Maryland residents in single-family detached homes and townhomes, but the application portal is now closed while the state works through the existing queue. That update matters because it shows how incentive programs can move from a policy idea into real household demand very quickly. A program with a $150,000 budget does not usually run out of room unless homeowners, contractors, and installers all see geothermal as a practical investment. In Maryland’s case, the fact that requests exceeded the full FY26 budget suggests the market is responding to both energy-cost concerns and long-term efficiency goals. What the program offers The Maryl...

"US Geothermal Tax Credits 2026: What the IRA/45Q Changes Mean for Developers"

US Geothermal Tax Credits in 2026: What Is Actually Still Alive After OBBBA For an industry that spent more than a decade building financial models around a stable federal incentive structure, 2026 has been a year of whiplash. The 30% federal geothermal tax credit that developers and homeowners built forecasts around is gone in one form and still alive in another, and even the IRS’s own public guidance has been confusing enough to trigger uncertainty across the market. That confusion is not a minor clerical issue. It is shaping investment decisions, contractor sales pitches, homeowner timelines, and project finance assumptions right now. If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...

Endurance Energy Tests World's First Subsea Geothermal Well at Axial Seamount

Endurance Energy Tests the World's First Subsea Geothermal Well: What the Axial Seamount Demonstration Really Proved What if geothermal energy did not need a power plant on land? What if electricity could be produced directly from the Earth's heat beneath the ocean, with generators sitting on the seafloor and sending power to coastal grids? On October 19, 2026, Seattle-based startup Endurance Energy announced a major step toward that idea. The company said it had drilled and completed the world's first subsea geothermal well and placed a 3-ton test power plant nearly a mile beneath the Pacific. It also reported net-positive electricity from heat at an active underwater volcano, according to its announcement on PR Newswire. The headline numbers are modest. The Adélie prototype produced more electricity than it used for about 8.7 seconds. During that time it delivered a median net output of about 2 kilowatts and a peak of 16.5 kilowatts. One detail matters more than any other...
