Alcatraz Gets a Solar Power Makeover

Alcatraz prison, home to a history of infamous residents like Al Capone and “Machine Gun Kelly,” now boasts 1,3000 solar panels, powering lights and appliances previously powered by diesel fuel ferried across the San Francisco Bay.

The $3.6 million project comes as a part of the efforts from the National Park Service (NPS) and the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) to bring clean energy to national parks and landmarks. Most importantly, it's saving money today by eliminating the transportation costs of diesel fuel to the island in addition to the associated maintenance costs and the price of the fuel itself.

A 307-kilowatt photovoltaic (PV) array sits on the main Cellhouse building, producing close to 400,000 kilowatt-hours of electricity per year. The NPS added other energy changes, including better lightbulbs and changes in operation, to reduce energy consumption.

When the sun isn't shining, a massive solar battery systems will keep power running—hidden from the view of the 1.4 million visitors to the island and prison each year.

Since 1995, the NREL's struggle to bring solar power to the island was halted by a historic landmark group protesting that the solar panels would be too visible, which they feared would hurt tourism. The NREL envisioned solar panels on both the New Industries Building and the Cellhouse, but problems with nesting birds and visibility held the project back.

Funds from the American Reinvestment and Recovery Act, coupled with progress made by the PV industry over the years, have finally made the project possible. With today's more efficient panels, an entire PV system now rests on the roof of the Cellhouse, where it is less visible.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
