Green Transition Business

RENOVA has been decarbonizing “power generation” through the development and operation of FIT (feed-in-tariff) based renewable power plants.

In order to further penetrate renewable energy and make green electricity readily available to everyone, it is essential to decarbonize the “power system”, including transmission and a robust power purchase mechanism. RENOVA provides “off-site PPAs” (Power Purchase Agreements) for non-FIT renewables and “ESS” (Energy Storage System) to stabilize the grid and variable renewable electricity.

Furthermore, to decarbonize processes which cannot be electrified, decarbonizing “industries” by using other forms of energy and feedstock is inevitable. RENOVA takes up the challenge to produce and supply “green hydrogen and ammonia”, “biomass-derived fuel”, SAF (sustainable aviation fuel), e-fuels and other renewable fuels to decarbonize transportation and industrial processes.

The decarbonization of the “power system” and “industry” is an extremely arduous and complex challenge. As what we can achieve alone is very limited, RENOVA is seeking various partners.

Non-FIT Renewables “Off-Site PPAs”

Many companies and their suppliers, including those committed to RE100, a global corporate renewable energy initiative for ambitious businesses committed to 100% renewable energy, are increasingly demanding renewable electricity. RENOVA responds to these needs by providing non-FIT renewable electricity through off-site PPAs.

• (1) Extensive capacity

  Leveraging our track record of developing and operating more than 1GW of FIT renewable energy projects, we rapidly develop and construct non-FIT renewable power plants for off-site PPAs, working closely with our partners.

• (2) Diverse sources

  Leveraging our experience in developing a wide range of renewable projects including solar PV, onshore and offshore wind, biomass, geothermal and hydro, we develop diverse renewable power plants to accommodate energy demand 24 hours a day, throughout the year.

• (3) Reliable supply

  Through extensive local community engagement and minimizing the environmental impacts at all stages of the project, we supply reliable and resilient renewable electricity by leveraging our in-house engineering and O&M (operation and maintenance) capabilities.

• (4) Added value

  We develop renewable power plants with ESS to stabilize the intermittent power output, offer co-development of renewable projects with our customers, and provide further “value added” such as on-site PPAs and the visualization of power generation and GHG (greenhouse gas) emission reductions.

RENOVA, working closely with our partners, continues to develop renewable projects throughout Japan for non-FIT off-site PPAs, delivering renewable power to the electricity retailers and large end-users.
We are actively seeking new partnerships with the electricity retailers and renewable project developers.

Balancing the supply and demand of unpredictable and intermittent renewable energy sources such as wind and solar becomes increasingly important to for the penetration of more renewable energy. RENOVA contributes to this effort by installing and operating ESSs at various locations that help balance the grid.

• (1) Stand-alone ESS for power grids

  To contribute to a constant and reliable supply of energy to the grid, we install and operate utility-scale ESSs with capacities of tens of MW in areas with large daily and/or seasonal gaps between supply and demand.

• (2) ESS integrated with renewable power plants

  To stabilize the fluctuating power output of unpredictable and intermittent renewable energy sources, we install and operate ESSs of appropriate capacity co-located with new and existing renewable power plants.

• (3) Other ESS (demand-side, etc.)

  To alleviate the imbalance between electricity supply and demand, we install and operate on-site and/or off-site ESSs of appropriate capacities for electricity retailers and end-users who extensively use renewable electricity.

RENOVA is developing utility-scale ESS projects throughout Japan and in Australia, the U.S. and Asia, as well as Himeji Energy Storage Facility in Japan and a hybrid wind and ESS project in American Samoa.
We are actively seeking new partnerships with landowners, aggregators, EPC companies and battery manufacturers.

“Green Hydrogen and Ammonia” to Decarbonize Difficult-to-Electrify Industries

While electrification and transition to renewable energy is one of the most effective means of decarbonization, many industries and processes are difficult to electrify. RENOVA will produce and supply green hydrogen and ammonia, sometimes considered the “ultimate clean energy”, at competitive costs to help decarbonize such industries.

Various companies and developers from the power, oil, gas, and other sectors have already announced many green hydrogen and ammonia projects worldwide.
While hydrogen storage and transportation still require innovation and time, such infrastructure is already in place for ammonia, which is traded globally at 20 million tons each year. The Japanese government has also announced a target to import 3 million tons of ammonia fuel annually by 2030 and 30 million tons by 2050.

• (1) Small-scale projects to meet local demand

  We are developing green hydrogen and ammonia projects ranging in size from several to hundreds of MW to meet local demand in neighboring and nearby regions, contributing to the decarbonization of local communities and industries.

• (2) Large-scale projects for export

  We are developing GW-scale projects in countries with competitive renewable energy cost and favorable business environment to export green ammonia, and hydrogen in the future, to large demand countries such as Japan in addition to meet local demand, contributing to global decarbonization.

RENOVA, in cooperation with local partners, is rapidly developing projects to produce “green” hydrogen and ammonia that can compete cost effectively with “gray” counterparts, by fully utilizing the project development, engineering, and finance and other capabilities fostered through the development of renewable energy projects.
RENOVA is developing such projects in Australia, Americas, and Europe, and is jointly developing a green ammonia project using surplus hydropower in Laos with Hitachi Zosen, following a pre-feasibility study supported by NEDO. We are actively seeking new partnerships with project developers, EPC companies, logistics companies, and hydrogen and ammonia users.

“Biomass-Derived Fuel” for the Effective Utilization of Unused Biomass Resources

Biomass-derived fuels are starting to be used in co-firing at coal-fired power plants and other difficult-to-electrify industries, in addition to the traditional use in dedicated biomass-fired power plants. While the use and demand have expanded, as there are still untapped biomass resources worldwide, RENOVA is developing projects to produce various biomass-derived fuels that add value to these resources and contribute to decarbonization.

• (1) Biomass pellets

  In addition to widely used wood resources, we develop projects to produce new pellet fuels with enhanced transportability and combustibility, from unexploited biomass sources such as rubber trees, agricultural residues, and by-products from the palm industry, and propose optimized combustion recipes for each fuel type.

• (2) Black pellets

  For biomass with limited use or difficult handling properties, we develop projects to produce cost effective pellets with minimal processing such as torrefaction to improve water resistance and grindability, optimized for each feedstock source.

• (3) Other renewable fuels

  For industries and processes which cannot use pellet fuels, we develop projects to produce renewable and bio diesel, sustainable aviation fuel (SAF), e-fuels and other fuels from various biomass sources to contribute to the decarbonization of wider industries.

RENOVA is developing projects to produce biomass pellets, black pellets, and other renewable fuels in North America and Asia Pacific, and is testing and evaluating new biomass-derived fuels and their combustion recipes.
We are actively seeking new partnerships with foresters, fuel traders, renewable fuel technology companies, and biomass-derived fuel users.
