The largest tidal power plant in the world

Indonesia will build the largest tidal power plant in the world in the straits of Larantuka at the Island of Flores. The power plant is designed to provide electricity to more than 100,000 residents in that area.

This Larantuka power plant project aligns with Indonesia’s commitment to increase the share of renewable energy in the total energy supply to 25% by 2025. It also commits to reduce the emission of CO2 by 300 million tonnes by 2030.

The tapping of ocean energy, consisting of wave and tidal energy to produce clean and cheaper power will grow significantly.  According to Market Research Future, the annual growth rate of the global wave and tidal market is expected to be more than 17% till 2023.

Please read this great article on “Larantuka Straits, Indonesia will be home to the largest tidal power plant in the world” written by Novrida Masli.

Lava Laze of Kilauea


Watch this spectacular USGS video showing lava laze formed by the lava of Kilauea volcano flowing into ocean at Kapoho bay on June 4, 2018.

The lava is from Kilauea Volcano’s lower east Rift Zone entering the ocean. The ocean entry is about a half-mile wide. The flow sends a large laze plume into the air along the coast.


What is lava laze?

When the lava flow goes into the ocean water, it boils the water and creates a white acidic plume. That’s laze.

“It’s a complex chemical reaction that occurs between the lava flow and seawater,” said Wendy Stovall, a volcanologist with the U.S. Geological Survey. “It creates a mixture of condensed acidic steam, hydrochloric acid gas and tiny shards of volcanic glass.”

From the air, the plume looks like exhaust from a factory or the white smoke released during a forest fire.

If you’re underneath the plume, a light sprinkle of rain as corrosive as battery acid can fall on you. The acid can burn your skin, irritate your eyes and make it difficult to breathe. In rare cases, the damage can be permanent.

Geothermal Plants near a Volcano

Geothermal plants can be safely situated near a volcano, says Dr. Roland Horne, Thomas Davies Barrow Professor in the School of Earth Sciences and Senior Fellow at the Precourt Institute for Energy at Standord University.

You can read the outstanding article from Stanford University titled Geothermal at the foot of Kilauea on this and on the recent volcano eruption of Mt. Kilauea in Hawaii at

In this article, Dr. Roland Horne discusses geothermal energy in the face of natural hazards and a way to tap the earth’s heat far from volcanoes in the future.

I highly recommend you read the article that I mention above. In this article you can also watch the awesome lava flow from a fissure of Mt. Kilauea on May 19, 2018 and learn about Stanford University’s School of Earth, Energy & Environmental Sciences.

Digital Rock Physics – Core Analysis Using Digital Technology

In the last decade, there has been an important breakthrough on how petroleum engineers and geoscientists obtained oil and gas reservoir rock properties.

Traditionally, reservoir rock properties or petro-physical properties such as porosity, pore size distribution, effective and relative permeability, capillary pressure, water saturation and other reservoir parameters are determined from Special Core Analysis (SCAL), electric logs and well pressure transient tests. In the recent years, a new method in determining rock properties using Digital Rock Physics (DRP) has gained serious attention from petroleum engineers, petro-physicists and geoscientists.

What is digital rock physics? Digital rock physics is also referred to as digital core analysis. In this measurement method, high-resolution digital images of the rock pores and mineral grains of selected reservoir core samples are made and analysed. These images are usually 3D digital X-ray micro-tomographic images. The rock properties are then determined using numerical simulation at the pore scale.

The significant benefit of this new DRP technology is now large quantity of complex reservoir parameters can be determined faster and more accurately than the traditional laboratory measurements or well testing methods.

Using the DRP technology to determine the rock properties, oil and gas companies can now analyse their reservoir capacity and performance more accurately and sooner during the field evaluation and development phase. This in turn allows them to develop and manage their reservoirs more efficiently and economically.

Green Hydrogen

Hydrogen is a clean and efficient energy source. It is being used to power hydrogen cars and buses in several environmentally conscious countries. Hydrogen cars are very clean. They have zero emission and they emit only water vapor. As an example, the city of Aberdeen in Scotland is using hydrogen buses to reduce emission and boost air quality at the city centre.

As energy carrier, hydrogen stores and delivers energy efficiently. Hydrogen cars uses fuel cells to convert the chemical energy stored in the hydrogen into electricity, whereas electric cars use the electricity stored in the car batteries to power the electric motors.

Although many compounds, especially hydrocarbons and water, contain lots of hydrogen atoms, free hydrogen is very scarce in nature. Our air has only .00005% of free hydrogen. Currently most hydrogen is produced from fossil fuel by stripping off the hydrogen atoms from the hydrocarbons. Therefore, hydrogen cars are not considered as totally green.

To make hydrogen cars truly green, people are considering using green hydrogen. Green hydrogen is hydrogen which is produced using electricity generated from renewable energy resources such as wind, solar and geothermal.

New Zealand is currently experimenting powering hydrogen cars using hydrogen produced using geothermal resources.

Toyota expects 30% of vehicles to be hydrogen powered by 2050.

Why People Need Oil Price Forecasts


People, companies and even countries want to know future price of oil because oil price influences what they do.
Individuals use the information for his or her investing such as whether to buy oil related shares.
Banks need it for giving out oil related loans.
Transportation companies use it to manage its fuel expenditures such as whether to buy or sell oil futures.
Oil companies need it to manage their operating and capital expenditures such as whether to drill or not to drill.
Oil exporting countries use it to determine its GDP.
Oil importing countries need it for planning its annual budget.
Perhaps the greatest role of oil price forecast is in IPOs and M&A.
