Malaysia reinvigorating curiosity in geothermal with 1st Geothermal Convention

Contributors on the 1st Malaysia Worldwide Geothermal Convention in Selangor, Malaysia (supply: Dr. Mohd Hariri Arifin)

The Southeast Asia area has earned a superb popularity within the area of geothermal energy technology. As of the tip of 2023, the Philippines and Indonesia have a mixed put in geothermal energy capability of 4370 MW, or about 27% of the worldwide put in capability. Taiwan additionally has working geothermal energy crops in Qingshui and Sihuangziping, and Thailand has had a 300-kW geothermal set up working for the reason that Nineteen Eighties.

Virtually surrounded by these powerhouses, it’s completely cheap that Malaysia has proven curiosity in creating its personal geothermal sector. As a part of these renewed efforts, Malaysia not too long ago held the primary Malaysia Worldwide Geothermal Convention (MIGC) within the premises of Universiti Kebangsaan Malaysia in Selangor.

Organized by Dr. Mohd Hariri Arifin from the Division of Earth Sciences and Setting at UKM, the occasion highlighted the analysis and exploration work being achieved on the geothermal websites in Malaysia, in addition to technical insights introduced by worldwide audio system. Contributors additionally took half in a workshop and a area journey to among the potential geothermal websites in Peninsular Malaysia.

Reinvigorating curiosity for geothermal in Malaysia

Malaysia had already ventured into geothermal growth greater than a decade in the past, initially figuring out the Apas Kiri website in Tawau in Sabah Malaysia as having good geothermal potential. Over the next years, the challenge acquired investments and authorities funding, constructing in direction of a industrial operations date by 2017.

Issues didn’t prove as anticipated for the Apas Kiri challenge, with the positioning seemingly deserted by late 2018 and the license revoked by Malaysia’s Sustainable Vitality Growth Authority (SEDA). On the time, authorities officers said that there had been no progress within the challenge since 2016 and that the corporate had already ceased its operations.

Regardless of the setback, curiosity for geothermal growth is coming alive once more in Malaysia. Earlier this 12 months, a tripartite settlement was signed between UK-based consultancy Primeval Vitality, the Institute of Geology Malaysia (IGM), and Digital Geoscience International Sdn Bhd (DGeG) to conduct thorough assessments of geothermal power potential in Malaysia.

There’s nonetheless some curiosity within the Apas Kiri website, however there has additionally been a shift in focus to creating non-volcanic scorching spring websites in Peninsular Malaysia simply north of Kuala Lumpur. Though preliminary targets are small in scale, the aspiration is to construct a primary “proof of idea” geothermal facility to assist spur extra assist from the federal government, the monetary sector, and personal builders.

“Our objective is to develop any of the promising websites in Malaysia for our first geothermal energy plant. It may be small, even simply 100 kW. We are able to begin with that, and perhaps it will possibly assist open the eyes of potential stakeholders,” stated Dr. Hariri. “After which we are able to go for MW scale, and even GW.”

“It is crucial for us to attempt. If we don’t attempt, then we are going to by no means know.”

Learnings from neighboring nations

One of many aims for holding the primary MIGC is to ask geothermal consultants from different nations to share their information and assist empower the native sector. As such, the occasion’s keynote audio system had been Dr. Yunus Daud from the College of Indonesia and Dr. Wipada Ngansom from Ramkhamhaeng College of Thailand.

Throughout his presentation, Dr. Daud mentioned the worth of geothermal exploration applied sciences specifically utilized to the characterization of low to medium-temperature geothermal sources. Floor manifestations in such techniques might not be so obvious, so distant sensing techniques and geophysical measurements are notably essential.

Dr. Ngansom additionally shared some perception on how geothermal websites in Thailand are evaluated and ranked based mostly on a system of constructive perspective components. Except for technical components together with reservoir dimension and temperature, constructive perspective components consider market and infrastructure concerns similar to terrain, proximity to market, and distance to energy distribution strains. This method offers easy-to-follow steerage on deciding on the recent spring websites with the very best potential. It’s also a great tool for speaking with native and nationwide choice makers, in addition to potential traders.

The discussions in the course of the keynote displays had been notably related for Malaysia within the context of the Ulu Slim scorching spring website. Situated simply north of Kuala Lumpur, Ulu Slim has been one of many focus areas of geothermal research achieved by UKM. Research point out that Ulu Slim is a fault-controlled geothermal useful resource with a radiogenic warmth supply.

A number of different worldwide audio system introduced in the course of the MIGC. From scaling mitigation in Dieng in Indonesia to slimhole drilling for geothermal exploration in Singapore, the worldwide expertise represented in the course of the occasion mirrored the extent of assist for Malaysia’s geothermal progress. As Malaysia works for its aspiration of getting its first geothermal energy plant, collaboration with worldwide consultants will undoubtedly be a part of its growth technique.

To this finish, UKM has been collaborating with Indonesia-based NewQuest Geotechnology to conduct geophysical research on their areas of curiosity. Dr. Hariri stresses that there are not any native contractors or service suppliers for magnetotelluric (MT) surveys, making this collaboration instrumental within the progress of geothermal analysis within the nation.

Excessive-potential websites for geothermal in Malaysia

A part of the convention was a area journey to among the high-potential geothermal websites in Peninsular Malaysia. Situated only a few hours north of Kuala Lumpur, the recent spring websites are getting used for geothermal analysis and are eyed for additional geothermal growth.

The Lojing scorching spring website positioned within the Lojing Highlands is being focused for the primary mini geothermal energy plant. A shallow effectively had already been drilled on the website to a depth of 138 meters, which is now producing scorching water at a temperature of round 78 °C. There are plans to drill a deeper effectively, however a driller with extra expertise might be wanted.

“We drilled to 140 meters, after which the native driller surrendered,” admitted Dr. Hariri. “We can’t go deeper as a result of the stress is kind of excessive and temperature is rising. Hopefully, we might be linked with an organization with the tools to assist our exploration work and assist us show the presence of this scorching reservoir.”

Offering steady electrical energy to the local people is without doubt one of the motivating components for geothermal growth in Lojing. Below present situations, the locals are depending on diesel mills for energy. “When the diesel runs out, then they’re at the hours of darkness,” says Dr. Hariri. Introducing geothermal energy also can create extra alternatives for the realm as a tourism and academic hub.

The Ulu Slim scorching springs, positioned round 85 kilometers south of Lojing, is one other website of curiosity. Ought to the positioning be developed for geothermal energy, it will possibly provide electrical energy to Malaysia’s nationwide automobile manufacturing unit, the so-called “Proton Metropolis.” UKM can also be working to determine a geothermal studying and analysis centre on the Ulu Slim website.

Detailed exploration of the Ulu Slim website had already been undertaken by NewQuest Geotechnology with suggestions for additional growth.

An optimistic view, however assist is required

Teams advocating for geothermal growth in Malaysia are extremely motivated and passionate, however there’s admittedly a scarcity of in-country abilities and expertise to totally notice their geothermal aspirations. “Geothermal continues to be fairly new for us and we do not need clear tips but for its growth. For this reason we preserve proposing geothermal initiatives and educating others in regards to the potential for geothermal,” stated Dr. Hariri.

“We’re in search of collaborations with those that need to be pioneers for geothermal in Malaysia. We’re not good in every part, so we’re very open to others with the experience.”

Dr. Hariri’s group can also be working with UKM Pakarunding to determine requirements for Environmental and Social Influence Research associated to geothermal growth. These are the preliminary phases in making a regulatory framework that can make geothermal growth in Malaysia safer and predictable, thus additionally attracting extra funding. Via the assistance of SEDA and different associated events, the objective is to create a extra enticing regulatory setting for geothermal growth in Malaysia.

As stated in one of many displays in the course of the convention, addressing the limitations to geothermal electrical energy and warmth growth in Malaysia would require concerted efforts amongst academia, business, and authorities businesses. The highway forward stays lengthy for Malaysia, however holding the MIGC has been an vital first step.
