Cellulosic Ethanol for Indonesian Farmers

Cellulosic Ethanol for Indonesian Farmers

Cellulosic Ethanol vs Bio-diesel

Like many other countries worldwide, Indonesia has ambitious goals for reducing reliance on fossil fuels. With a population just shy of 300 million people, the results of reducing petroleum consumption would be substantial.

Leaders within the country have expressed interest and intent to reduce reliance on fossil fuels; last year, the country’s president Joko Widodo announced that they are dedicating 700,000 hectares of land to cultivating renewable-based sugar ethanol.

However, small farmers have not seen the benefit of this transition toward bio-diesel production. Large palm oil firms dominate the industry, leaving small farmers without much hope in a transition that will benefit them as much as the environment.

According to Tenny Kristiana of the International Council on Clean Transportation, cellulosic ethanol could be the key ingredient to facilitate a boon in the lives of small farmers and Indonesia as a whole in the long run.

What could be done?

Cellulosic bio-ethanol is a bio-fuel that could be incredibly useful for Indonesian farmers due to its nature in the supply chain. The ethanol is created using traditionally considered waste products, like palm husks, trunks, and empty fruit bunches. These leftovers are either left to rot in the fields or sold overseas to countries like Japan, using the byproducts to fuel their own bio-ethanol industry.

Small farmers would benefit from selling these raw materials to bio-ethanol companies in Indonesia under long-term contracts guaranteeing the benefits for a long time. Expanding this domestic industry would also create jobs in transportation, manufacturing, and plantation work.

Indonesia specifically has large potential in developing its cellulosic ethanol industry, with estimates ranging up to 2 million kiloliters from palm residues alone. This could be the major push that Indonesia needs to support its domestic supply chain and create long-term stability in the job market that they need.

Being Done Elsewhere Too

This push towards sustainable development in cellulosic ethanol production is not without precedent. Brazil has one of the most successful bio-ethanol programs in the world, making up 50% of all fuel consumption in the gasoline market by April 2008.

This push would also reduce reliance on trade with foreign countries, as the fuel supply would be provided domestically, leaving Indonesia less vulnerable to changes outside its borders.

As the industry expands, they could also expand the inputs in ethanol production. Sugar cane bagasse, corn stalks, rice stems, and others could be used to create bioethanol.

While the long-term goal for many countries is to decarbonize and get off of ICEs entirely, in other countries, the costs outweigh the benefits. In the short to medium term, domestic bioethanol production could be necessary to help small farmers and the Indonesian society at large to buy into the green transition.

European Investment Bank supports thermal, gravity energy storage projects

European Investment Bank supports thermal, gravity energy storage projects

The EU’s European Investment Bank has pledged support for a long-duration thermal energy storage project and a gravity-based energy storage demonstration project.

They have been selected among 15 projects defined as large-scale — each requiring capital costs of more than €7.5 million (US$8.5 million) — through EU Innovation Fund grants for Project Development Assistance (PDA), administered by the bank.

A total of 311 applications were received for clean energy or decarbonisation projects after the call for submissions opened last summer.

Of these, seven were selected to receive direct funding from a €1.1 billion budget and include hydrogen, carbon capture and storage, advanced solar cell manufacturing and other technologies.

The 15 among which the two energy storage projects were selected will receive PDA, technical assistance for various stages of their development.

The other 13 projects cover technologies including wind propulsion for cruise ships, hydrogen fuel cells for marine vessels, green methanol production, greenhouse gas (GHG) and carbon capture and storage, bioethanol, power-to-liquid for aviation fuels and other areas.

There is also an electric vehicle (EV) battery project, which will use ultra-pure electrolyte salt to improve lithium-ion batteries and a project to develop and upscale the synthesis of curved graphene and electrode production technologies.

 

Thermal energy storage project Sun2Store

Sun2Store, a 100MW/1,000MWh thermal energy storage project in Spain was selected for a PDA agreement. Using technology developed by US startup Malta Inc, the project will enable 10-hour duration storage of energy.

Malta Inc has developed a technology it calls ‘pumped heat’ electricity storage, which could provide up to 200 hours of storage, although the company is largely targeting 10 – 12 hour applications. It converts electricity to heat, which is then stored in molten salt. Simultaneously, the system produces cold energy stored in special vats of an anti-freeze-like cooling liquid.

The hot and cold energy are then converted back into electricity as required, using a temperature difference-driven heat engine. The company has raised funds from investors including Bill Gates’ Breakthrough Energy Ventures and is one of the founding members of the international Long Duration Energy Storage Council.

It has deals in place with equipment manufacturers Bechtel and Siemens Energy for co-development and supply of key components.

Funds have been granted to Malta Inc’s European affiliate company, Malta Iberia Pumped Heat Electricity Storage (Malta Iberia). The EIB will provide technical assistance to Malta Iberia, including an independent technology assessment, which will verify the storage facility’s key technical parameters.

Malta Inc recently announced plans for a similar-sized project in Canada.

 

Gravity storage project GraviSTORE

Scotland-headquartered startup Gravitricity was the other energy storage system industry recipient of a PDA agreement through the Innovation Fund.

The EIB will support Gravitricity’s plans to build a full scale 4-8MW project in a former mine shaft.

Located in mainland Europe, the project follows a 250kW demonstrator which operated in Scotland’s capital city Edinburgh throughout the summer and for which specialists appointed by the EIB have begun evaluating test results.

The results of the Edinburgh demonstrator are to be combined with a review of local revenue streams to produce a commercial risk assessment that will inform detailed design and development activities.

“We already have a high level of confidence in our technology and its ability to store energy effectively. What these studies will bring is increased understanding and confidence in how a full-scale project will play into a specific energy market,” said Chris Yendell, project development manager at Gravitricity.

Gravitricity’s energy storage solution works by raising weights in a deep shaft, with disused mine shafts currently being targeted by the firm, and releasing them when energy is required. Its proposed single weight full scale system could deliver up to 2MWh of energy storage, with future multi-weight systems having the potential for a capacity of 25MWh or more.

Alongside the test evaluations, the EIB has now also committed 120 days of consultancy time to advance the full scale project.

In October, Gravitricity engineers visited the recently mothballed Staříč mine in the Moravian Silesian Region of Czechia to investigate its potential for the project. The Gravitricity team is to head to mainland Europe later in January to further evaluate their shortlist, with a final selection decision expected within the next few months.

The firm is also exploring opportunities for a purpose-built prototype shaft at a brownfield location in the UK, where gravity storage could be combined with hydrogen and inter-seasonal heat storage.
