State power companies get cybersecurity orders

2015_02_cybersecurityThe Ministry of Trade, Industry and Energy (MOTIE) says state-run power companies will spend a total of 79 billion won ($71 million) on cybersecurity this year, an increase of 18 billion won. Minister Yoon Sang-jick on Thursday afternoon met with CEOs of 17 state-run energy companies, including the Korea Electric Power Corporation (Kepco), Korea Hydro and Nuclear Power Corporation (KHNP) and Korea Power Exchange.

Kepco, the nation’s sole power distributor, will get 28.4 billion won and KHNP 11.5 billion won. Each of the other companies will receive up to 4 billion won. The budget will be mostly spent on hiring security experts, maintaining internal network infrastructure and expanding maintenance teams. All 17 power companies will have to structure their internal network in five systems, from the current three.

The current system is broken down into a regular network that can access the Internet, an intranet that mainly deals with document processing, and an exclusive network to control the power plant. From now on, the intranet will have an additional system for confidential technical documents like power plant blueprints. The power plant control system will also be split into two networks to beef up security.

A group of researchers have developed a next-generation, more economical perovskite-based solar battery, thereby creating the world’s most efficient solar cell. Led by Professor Seok Sang-il of Sungkyunkwan University (SKKU), the team announced on January 9 that they have successfully developed a new perovskite solar cell technology. The newly developed solar cells are priced at one third the price of existing silicon solar cells and show an efficiency performance rate of 20.1 percent, equivalent to existing silicon solar cells.

This is now the most efficient solar cell officially recognized by the U.S.-based National Renewable Energy Laboratory (NREL).

Currently, silicon solar cells account for about 90 percent of the solar cell market. Silicon solar cells are made from high-purity silicon. They are highly efficient at transforming solar energy into electric energy. Their weaknesses, however, is their complicated production process and expensive price.

Busan facility can recycle just about anything

2013_04_busan_recyclingAt the Saenggok eco-recycling plant in Gangseo District, Busan, combustible waste is turning into another source of fuel energy.  When the JoongAng Ilbo visited Busan E&E April 9, trash was moving on a long conveyor belt to dry, which would then be used as fuel for a power plant located next to the plant. The eco-recycling plant burns 900 tons of trash for a period of 16 hours a day, generating 25 megawatts of electricity per hour.

The garbage that usually is buried in a landfill generates nearly 25 billion won ($22 million) worth of energy a year through the recycling process. Saenggok eco-recycling center is the largest in the country at 1.16 million square meters (287 acres).

The Busan Metropolitan Government invested 20.24 billion won to further upgrade the facility, which was built in 1994. At the complex are seven recycling facilities, some of which are in full operation while some are partly operational.  Each facility sorts out what could be recycled to be used as fuel with conveyor belts.

Government plans 18 thermal plants

Korea will build as many as 18 thermal power plants by 2027 while also significantly expanding the generation capacity of clean, renewable power sources, such as solar and wind farms, the government said yesterday. The move comes as the country’s electricity consumption is expected to grow by an annual average of 2.2 percent, from 482.5 billion kilowatt-hours this year to 655.3 billion kilowatt-hours by 2027.

The country’s peak power demand is expected to grow at a faster rate of 2.4 percent per year from 79.7 million kilowatts in 2013 to over 110 million kilowatts in 2027, according to the Ministry of Knowledge Economy.

The government sets a 15-year power supply plan in place every two years. The latest is the sixth of its kind. Under the new plan, the government seeks to increase the total generation capacity of clean, renewable sources to 12 percent of total consumption in 2027, compared with only 7 percent in 2025 under the fifth power supply plan announced two years earlier.

Steel industry bets on business diversification

The nation’s major steelmakers are diversifying into non-core businesses such as energy, construction and agriculture to shore up falling profits.

POSCO, the world’s fourth-largest steelmaker by output, has cut its number of subsidiaries to 46 from 70 as of Jan., 1 mainly by merging those with overlapping businesses, the company said in a press release. The number of POSCO’s affiliates surged after takeover deals for the past few years, including Daewoo International, a trading company specializing in oil and gas exploration overseas, in 2011.

“On the group level, POSCO has driven in-house reorganization since March last year under the three principles of strengthening core businesses, trimming overlapped businesses and closing non-core businesses without cutting personnel,” a company official said. The steel giant will wrap up the reorganization by the end of this year and the number of its subsidiaries is expected to be cut to 30. “The POSCO streamlining came amid diversification of its business portfolio into non-steel sectors,” Byun Jong-man, an analyst from Woori Investment and Securities, said.

South Korea and U.S. halt talks on nuclear energy cooperation

South Korea and the United States have called a halt to their sensitive negotiation on future nuclear energy cooperation, an informed source here said Thursday. “Actual talks are deemed difficult this year,” said the source well versed in the issue, requesting anonymity.

South Korea’s Lee Myung-bak government “has decided to pass negotiations to the next administration,” added the source. Lee is to retire in February. Seoul instead plans to focus on efforts to publicize its position on the matter for the time being, the source said.

South Korean officials argue that the current pact with the U.S. is obsolete. The existing pact, signed in 1974 and set to expire in 2014, bans South Korea from enriching uranium even for commercial purposes and reprocessing nuclear waste from about two dozen reactors using U.S.-supplied nuclear materials.

Scientists develop fast recharging material for lithium-ion batteries

A group of South Korean scientists has developed a new material for a secondary or rechargeable battery that can be fully recharged in just a matter of minutes, the science ministry said Monday. The development of such a battery could significantly raise the popularity of electric vehicles whose lithium-ion batteries currently take hours to recharge, according to the Ministry of Education, Science and Technology.

Conventional batteries use only powdered nanoparticle materials to form a dense, multi-layered structure that can store and give off energy. The new battery, on the other hand, uses the same type of nanoparticle materials that are first resolved in a solution that contains graphite, which later is carbonized to form a dense network of conductors all throughout the electrodes of the battery, the ministry said.

As a result, all energy-holding particles of the new battery start recharging simultaneously while the same particles in conventional batteries begin recharging in order from the outermost particles to the innermost.
